Oil Pollution Prevention and Response; Non-Transportation-Related 
Onshore and Offshore Facilities

AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA or the Agency or we) 
is amending the Oil Pollution Prevention regulation promulgated under 
the authority of the Clean Water Act. This rule includes requirements 
for Spill Prevention, Control, and Countermeasure (SPCC) Plans, and for 
Facility Response Plans (FRPs). The final rule includes new subparts 
outlining the requirements for various classes of oil; revises the 
applicability of the regulation; amends the requirements for completing 
SPCC Plans; and makes other modifications. The final rule also contains 
a number of provisions designed to decrease regulatory burden on 
facility owners or operators subject to the rule, while preserving 
environmental protection. We expect that today's rule will reduce the 
paperwork burden associated with SPCC requirements by approximately 
40%. We have also made the regulation easier to understand and use.

DATES: This rule is effective August 16, 2002.

ADDRESSES: The official record for this rulemaking is located in the 
Superfund Docket at 1235 Jefferson Davis Highway, Crystal Gateway 1, 
Arlington, Virginia 22202, Suite 105. The docket numbers for the final 
rule are SPCC-1P, SPCC-2P, and SPCC-7. The record supporting this 
rulemaking is contained in the Superfund Docket and is available for 
inspection by appointment only, between the hours of 9 a.m. and 4 p.m., 
Monday through Friday, excluding legal holidays. You may make an 
appointment to review the docket by calling 703-603-9232. You may copy 
a maximum of 100 pages from any regulatory docket at no cost. If the 
number of pages exceeds 100, however, we will charge you $0.15 for each 
page after 100. The docket will mail copies of materials to you if you 
are outside of the Washington, DC metropolitan area.

    ``NAICS'' refers to the North American Industry Classification 
System, a method of classifying various facilities. The NAICS was 
adopted by the United States, Canada, and Mexico on January 1, 1997 to 
replace the Standard Industrial Classification (SIC) code. This table 
is not intended to be exhaustive, but rather provides a guide for 
readers regarding entities likely to be regulated by this action. It 
lists the types of entities of which we are now aware that could 
potentially be regulated by this action. Other types of entities not 
listed in the table could also be regulated. To determine whether your 
facility could be regulated by this action, you should carefully 
examine the criteria in Secs. 112.1 and 112.20 of title 40 of the Code 
of Federal Regulations and of today's rule, which explain the 
applicability of the rule. If you have questions regarding the 
applicability of this action to a particular entity, consult the person 
listed in the FOR FURTHER INFORMATION CONTACT section.

II. Introduction

A. Statutory Authority

    Section 311(j)(1)(C) of the Clean Water Act (CWA or Act), 33 U.S.C. 
1251, requires the President to issue regulations establishing 
procedures, methods, equipment, and other requirements to prevent 
discharges of oil from vessels and facilities and to contain such 
discharges. The President has delegated the authority to regulate non-
transportation-related onshore facilities under section 311(j)(1)(C) of 
the Act to the U.S. Environmental Protection Agency. Executive Order 
12777, section 2(b)(1), (56 FR 54757, October 22, 1991), superseding 
Executive Order 11735, 38 FR 21243. By this same Executive Order, the 
President has delegated similar authority over transportation-related 
onshore facilities, deepwater ports, and vessels to the U.S. Department 
of Transportation (DOT), and authority over other offshore facilities, 
including associated pipelines, to the U.S. Department of the Interior 
(DOI). A Memorandum of Understanding (MOU) among EPA, DOI, and DOT 
effective February 3, 1994, has redelegated the responsibility to 
regulate certain offshore facilities located in and along the Great 
Lakes, rivers, coastal wetlands, and the Gulf Coast barrier islands 
from DOI to EPA. See Executive Order 12777, section 2(i) regarding 
authority to redelegate. The MOU is included as Appendix B to 40 CFR 
part 112. An MOU between the Secretary of Transportation and the EPA 
Administrator, dated November 24, 1971 (36 FR 24080), established the 
definitions of non-transportation-related and transportation-related 
facilities. The definitions from the 1971 MOU are included as Appendix 
A to 40 CFR part 112.

B. Background of This Rulemaking

    Part 112 of 40 CFR outlines the requirements for both the 
prevention of and the response to oil spills. The prevention aspect of 
the rule requires preparation and implementation of Spill Prevention, 
Control, and Countermeasure (SPCC) Plans. This rulemaking affects SPCC 
and FRP requirements. The SPCC requirements were originally promulgated 
on December 11, 1973 (38 FR 34164), under the authority of section 
311(j)(1)(C) of the Act. The regulation established spill prevention 
procedures, methods, and equipment requirements for non-transportation-
related onshore and offshore facilities with aboveground storage 
capacity greater than 1,320 gallons (or greater than 660 gallons in a 
single container), or completely buried oil storage capacity greater 
than 42,000 gallons. Regulated facilities were also limited to those 
that, because of their location could reasonably be expected to 
discharge oil in harmful quantities into the navigable waters of the 
United States or adjoining shorelines.
    We have amended the SPCC requirements a number of times, and those 
amendments are described in an October 22, 1991 Federal Register 
proposed rule. 56 FR 54612. In the October 1991 document, in addition 
to the description of past amendments, EPA proposed new revisions that 
involved changes in the applicability of the regulation and the 
required procedures for the completion of SPCC Plans, as well as the 
addition of a facility notification provision. The proposed rule also 
reflected changes in the jurisdiction of section 311 of the Act made by 
amendments to the Act in 1977 and 1978. We have finalized some of those 
proposed revisions, with modifications, in this rule.
    On February 17, 1993, we again proposed clarifications of and 
technical changes to the SPCC rule. We also proposed facility response 
planning requirements to implement the Oil Pollution Act of 1990 (OPA). 
58 FR 8824. The proposed changes to the SPCC rule included 
clarifications of certain requirements, response plans for facilities 
without secondary containment, prevention training, and methods of 
determining whether a tank would be subject to brittle fracture. We 
promulgated the facility response planning requirements of the 1993 
proposal on July 1, 1994, (59 FR 34070), and they are codified at 40 
CFR 112.20-112.21. We have finalized the proposed 1993 prevention 
requirements, with modifications, in this rule.
    In 1996, EPA completed a survey and analysis of SPCC facilities. 
The survey was designed to ensure that data on the sampled facilities 
could be statistically extrapolated to the nation as a whole for all 
facilities regulated by EPA's SPCC regulation. We used the results of 
that survey and analysis to develop a proposed rule affecting SPCC 
facilities on December 2, 1997. 62 FR 63812. The survey and analytical 
results are part of the administrative record for this rulemaking.
    The purpose of the 1997 proposal was to reduce the information 
collection burden imposed by the prevention requirements in the SPCC 
rule and the FRP rule without creating an adverse impact on public 
health or the environment. We also proposed changes in information 
collection requirements for facility response plans, but have withdrawn 
them in this rulemaking. Those changes would have affected the 
calculation of storage capacity at certain facilities for response plan 
purposes. 62 FR 63816. However, see new Sec. 112.1(d)(6). The 1997 SPCC 
proposals, as modified, are finalized in this rule.
    On April 8, 1999, we proposed revision to facility response plan 
requirements. 64 FR 17227. The main purpose of the proposal was to 
provide a more specific methodology for planning response resources 
that can be used by an owner or operator of a facility that handles, 
stores, or transports animal fats and vegetable oils. We finalized that 
proposal on June 30, 2000. 65 FR 40776. The final rule included four 
new definitions that are applicable to all of part 112.

III. Summary of Major Rule Provisions

    For your convenience, we have developed a table showing a summary 
of the major revisions in this rule. The table does not always use 
exact rule text, but summarizes rule provisions. For exact rule text, 
see 40 CFR part 112 (2000) for text of the current rule; for exact text 
of the revised rule, see the rule text following this preamble.

IV. Discussion of Issues

    Below is a discussion of the major issues for which we solicited 
comments in the 1991, 1993, and 1997 proposals. We also discuss the use 
of industry standards to comply with the rule. Following these issues, 
we discuss the revisions to each section and the major comments 
received, as well as responses to those comments. A detailed Response 
to Comments document addressing all comments is also part of this 
rulemaking and may be found in the administrative record for this rule.

A. Reorganization of the Rule

Background
    In 1991, EPA proposed to reorganize the SPCC rule based on facility 
type. The purpose of that proposed reorganization was to clarify SPCC 
Plan requirements for different types of facilities. In this 
rulemaking, we are dividing the rule into subparts. Subpart A consists 
of an applicability section, definitions, and general requirements for 
all facilities. Subparts B and C outline the requirements for different 
types of facilities storing and using different types of oils. Subpart 
B is for facilities storing or using petroleum oils or other non-
petroleum oils, except those oils covered by subpart C. Subpart C is 
for facilities storing or using animal fats and oils and greases, or 
fish and marine mammal oils; and, oils of vegetable origin, including 
oils from seeds, nuts, fruits, and kernels. Subpart D is for response 
requirements.
    If you have already prepared an SPCC Plan, you were required to 
follow the sequence of Sec. 112.7 of the current rule, prior to today's 
revisions. Today, we are reorganizing that portion of the rule into 
Secs. 112.7 through 112.15, based on facility type and type of oil. 
Under the introduction to Sec. 112.7 of today's rule, if your Plan does 
not follow the revised sequence, you must supplement it with a section 
cross-referencing the location of requirements listed in the revised 
rule and the equivalent requirements in your Plan. To assist you in 
preparing this cross-reference, the following table lists each 
requirement in the revised rule, provides the corresponding paragraph 
of the current rule, and leaves a space where you can show the location 
of the provision in your Plan. We have put this rule, including the 
table below, on our website for your convenience. You may download it 
for your use. See our Web site at www.epa.gov/oilspill.
    Under the revised rule, Sec. 112.7 sets out the general 
requirements for SPCC Plans for all facilities and all types of oil. 
Sections 112.8 to 112.11 set out the SPCC Plan requirements for 
petroleum oil and for non-petroleum oils other than animal fats and 
vegetable oils. Sections 112.12 to 112.15 set out the SPCC Plan 
requirements for animal fats and oils and greases, and fish and marine 
mammal oils; and for oils of vegetable origin, including oils from 
seeds, nuts, fruits, and kernels.

    In 1995, Congress enacted the Edible Oil Regulatory Reform Act 
(EORRA), 33 U.S.C. 2720. That statute mandates that most Federal 
agencies differentiate between and establish separate classes for 
various types of oils, specifically: animal fats and oils and greases, 
and fish and marine mammal oils; oils of vegetable origin; petroleum 
oils, and other non-petroleum oils and greases. In differentiating 
between these classes of oils, Federal agencies are directed to 
consider differences in the physical, chemical, biological, and other 
properties, and in the environmental effects, of the classes. In 
response to EORRA, as noted above, we have divided the requirements of 
the rule by subparts for facilities storing or using the various 
classes of oils listed in that act.
    Because at the present time EPA has not proposed differentiated 
SPCC requirements for public notice and comment, the requirements for 
facilities storing or using all classes of oil will remain the same. 
However, we have published an advance notice of proposed rulemaking 
seeking comments on how we might differentiate among the requirements 
for the facilities storing or using various classes of oil. 64 FR 
17227, April 8, 1999. If after considering these comments, there is 
adequate justification for differentiation among the requirements for 
those facilities, we will propose rule changes.

B. Plain Language Format

    We have rewritten the SPCC rule in a plain language format to make 
it clearer and easier to use. A plain language format includes maximum 
use of the active voice; short, clear sentences; and, in this rule, a 
summary table of the major regulatory changes. This format is part of 
the Agency's ongoing efforts in regulatory reinvention. While we have 
made substantive changes in some provisions, the plain language changes 
are only editorial. The plain language format used in today's rule may 
appear different from other rules, but it establishes binding, 
enforceable legal requirements.
    In this preamble, as in the rule text, we often use the pronoun 
``he'' as a generic term. ``He'' does not necessarily mean a man; it 
may be a woman, or in some cases, a business organization when 
referring to an owner or operator.

C. ``Should to Shall to Must'' Clarification

Background
    EPA has always considered that Sec. 112.3 of the SPCC rule requires 
that SPCC Plans be prepared in accordance with Sec. 112.7, which in 
turn requires that Plans be prepared in accordance with good 
engineering practice. However, clarification of the current rule is 
necessary because of confusion on the part of some facility owners or 
operators who have interpreted the current rule's use of the words 
``should'' and ``guidelines'' in Sec. 112.7 as an indication that 
compliance with the applicable provisions of the rule is optional. The 
rule used the words ``should'' and ``guidelines'' to provide 
flexibility for facilities with unique circumstances. Those 
circumstances might be such that mandated regulatory provisions would 
not be in accord with good engineering practice. Therefore, the rule 
gave facilities the opportunity to provide alternative methods that 
achieve equivalent environmental protection, or to show that the 
provisions were inapplicable based on specific circumstances.

[[Page 47052]]

    In 1991, we proposed to clarify that misunderstanding by generally 
substituting ``shall'' in place of ``should'' throughout the 
reorganized rule. In today's final rule, we have editorially changed 
``shall'' to ``must'' in furtherance of the Agency's ``plain language'' 
objectives. The ``shall'' to ``must'' is not a substantive change, but 
merely an editorial change. Nor will the change add to the information 
collection burden. We have always included requirements prefaced by 
``should'' in the information collection burden for the rule. We will 
continue to provide flexibility for an owner or operator who can 
explain his reasons for nonconformance with rule requirements, and can 
provide alternate measures from those specified in the rule, which 
achieve equivalent environmental protection. Section 112.7(a)(2) will 
provide such flexibility. In the exercise of our authority to inspect 
facilities and SPCC Plans, we reserve the right to find that such 
alternate methods do not provide equivalent environmental protection. 
In such cases, we would require the owner or operator of the facility 
to amend the SPCC Plan to provide equivalent environmental protection.
    Comments. Guidance. Several commenters supported the proposed 
change. One asked that discretionary provisions might be better placed 
in a separate guidance document. Several commenters were concerned that 
there are no guidance documents outlining equivalency as provided in 
proposed Sec. 112.7(a)(2) and that it may be impossible to prove 
equivalency to EPA.
    PE certification. Other commenters suggested that if the 
Professional Engineer (PE) certified the Plan as adequate for the 
facility, then the mandated requirements were unnecessary, as he would 
have determined that all appropriate equipment and planning is in 
place.
    Substantive change. Some commenters argued that the proposal was a 
substantive change, contrary to legislative intent, and that we failed 
to give opportunity for proper notice and comment, as required by the 
Administrative Procedure Act.
    Small production facilities. One commenter suggested that the 
clarification should not apply to small production facilities, defined 
as those with less than 3000 barrels of storage capacity, because those 
facilities would suffer severe hardship as a result.
    Response to comments. Guidance. EPA agrees with the comment that 
recommendations have no place in this rule because we do not wish to 
confuse the regulated public as to what is mandatory and what is 
discretionary. Instead, some recommendations are discussed in the 
preamble to this document, while others can be found in separate 
guidance documents or policy statements. When the rule or preamble is 
silent, or no published guidance or policy documents exist, we will 
generally use industry standards as guidance for rule compliance.
    PE certification. While we generally agree that certification by a 
PE should show that all necessary equipment and planning are in place, 
we reserve the right to make a determination that additional measures 
may be necessary to comply with the rule. EPA made it clear in proposed 
Sec. 112.3(d), which is finalized today, that a PE certification does 
not relieve the owner or operator of the duty to prepare and fully 
implement an SPCC Plan in accordance with the rule's requirements.
    Substantive change. We disagree that the change is either 
substantive or contrary to legislative intent. Section 311(j)(1)(C) of 
the Act authorizes the President and, through delegation, EPA, to 
establish ``procedures, methods, and equipment and other requirements 
for equipment to prevent discharges of oil and hazardous substances 
from vessels and from onshore facilities and offshore facilities, and 
to contain such discharges.'' That authority is ample to provide the 
basis for a mandatory SPCC rule, that is, a rule that establishes 
``requirements * * * to prevent discharges.''
    We also disagree that the proposed rule failed to provide proper 
notice and comment. The preamble to the 1991 proposed rule fully 
explained the rationale for the proposed change (56 FR 54620, October 
22, 1991), and numerous commenters responded. Furthermore, we have 
always interpreted and enforced our rules as mandatory requirements.
    EPA recognizes, however, that this clarification may result in 
certain owners or operators of regulated facilities recognizing for the 
first time that they have been and are subject to various provisions of 
part 112. Such owners and operators should, of course, take all 
necessary steps to come into compliance with this part as soon as 
possible. In exercising its prosecutorial discretion, the Agency always 
takes into account the good faith and efforts to comply of an owner or 
operator who has been in noncompliance with applicable laws and 
regulations when deciding whether or not to take an enforcement action.
    Small production facilities. We disagree that the ``should'' to 
``must'' change will generally pose a severe hardship for small 
production facilities. As noted above, EPA has always interpreted the 
``shoulds'' as ``musts.'' Further, when a particular requirement is not 
feasible for a particular facility, under Sec. 112.7(a)(2) that 
facility may explain the reasons for nonconformance with the 
requirement, and provide alternate measures that achieve equivalent 
environmental protection.

D. Professional Engineers (PEs)

    Background. In the preamble to the 1991 proposal (56 FR 54618), EPA 
posed several questions to commenters regarding how PEs could help to 
implement the SPCC Plan. An owner or operator of a facility is required 
to secure the certification of a PE on an SPCC Plan, and on technical 
amendments to the Plan. By means of this certification, the PE attests 
that the Plan or the amendment has been prepared in accordance with 
good engineering practice.
1. State Registration
    Background. We solicited comments on the advantages and 
disadvantages associated with the PE being registered in the State in 
which the facility is located. EPA noted that ``a requirement that a PE 
be licensed in the State in which the facility is located would allow 
the State licensing board to more easily address the actions of the PE 
under its jurisdiction, and that the PE may have greater familiarity 
with the State and local requirements related to the facility under 
review.'' 56 FR 54619.
    Comments. Favorable comments. Several commenters supported a 
requirement that the PE be registered in the State in which the 
facility is located. The rationales often expressed were that: (1) 
Letting any PE certify any SPCC Plan effectively removed the PE from 
the supervision of the State board; and, (2) familiarity with the State 
and local requirements related to the facility as well as the State 
itself are essential for viable SPCC Plans. One commenter suggested 
that when an out-of-State PE prepares the Plan, the Plan should bear 
the seal of the PE who prepared the Plan along with the seal of a PE 
registered in the State in which the facility is located, assuring that 
the proposed Plan conforms to any additional State requirements.
    Opposing comments. Opposing commenters argued that: (1) A State 
licensing board will address the actions of an engineer regardless of 
the engineer's location when he applies his seal; (2) suggestions that 
the potential liability of the engineer might be limited if the 
engineer holds an out-of-State license are specious; (3) SPCC Plan

[[Page 47053]]

preparation is a Federal activity, therefore, it is unnecessary to have 
State registration; and, (4) such a requirement would reduce the 
available pool of qualified PEs. One commenter volunteered that the 
proposal was ``superfluous'' because the practice of engineering in a 
State without being professionally registered in that State is unlawful 
in most States.
    Response to comments. We agree with commenters that it is 
unnecessary that the PE be registered or licensed in the State in which 
the facility is located because any abuses will be corrected by the 
licensing jurisdiction. We also agree that such a requirement might 
unnecessarily reduce the availability of PEs and increase the cost of 
certification without any tangible benefits. The professional liability 
of a PE would likely be unaffected by the place of his registration. 
When State law precludes a PE from applying his seal if he is not 
licensed in that State, the question of State registration becomes 
moot. However, that is not the case in every State.
    We also disagree that if a PE is not licensed in the State, he will 
be unfamiliar with State and local requirements for the facility. Any 
PE may become familiar with both Federal and State and local 
requirements for a facility. Therefore, to require that the PE be 
registered in the State in which the facility is located would impose 
unnecessary financial burdens on the facility and would challenge the 
integrity of the PE. Such a requirement would also reduce the pool of 
PEs available for facilities.
2. PEs Employed by the Facility
    Background. EPA asked whether the rule should specify that the PE 
not be an employee of the facility or have any other direct financial 
interest in the facility. This request for comment had its origin in a 
U.S. General Accounting Office (GAO) report issued on February 22, 
1989, ``Inland Oil Spills: Stronger Regulation and Enforcement Needed 
to Avoid Future Incidents'' (GAO/RCED-89-65).'' The GAO report 
recommended that EPA evaluate the advantages and disadvantages of 
requiring facilities to obtain certifications from independent 
engineers. EPA noted that ``not having the PE otherwise associated with 
the facility may avoid any potential conflicts of interest or 
appearance of conflicts of interest that could arise from allowing an 
employee of a regulated party to certify a SPCC Plan.'' 56 FR 54619. On 
the other hand, for both the issues of whether to require State 
registration and whether to allow PEs employed by the facility to 
certify SPCC Plans, EPA noted that some organizations objected to the 
proposals as ``challenging the integrity of professional engineers.'' 
56 FR 54619. We also pointed out that some professional organizations 
believe that such requirements ``would impose substantial costs without 
enhancing the integrity of the certification process.'' 56 FR 54619.
    Comments. Favorable comments. Several commenters supported a 
requirement that the PE not be an employee of the facility or not have 
a direct financial interest in it. The rationales most often asserted 
were: (1) A Plan would better satisfy regulatory objectives and better 
serve the public; (2) the Plan would be less subject to compromise by 
other factors; (3) Plan certification is less likely to be a coerced or 
superficial effort, and undue economic and moral pressures would be 
avoided; (4) more cooperative efforts among regulatory bodies, 
engineers, and the facility would be possible; (5) more economic and 
effective Plan development is assured; and, (6) more competent and more 
professional Plan development is guaranteed.
    Opposing comments. Opposing commenters asserted that: (1) Such a 
proposal would limit the availability of PEs, leading to delays in Plan 
certification; (2) administrative action to correct abuses would be a 
better approach; and, (3) such an approach insults the ethical 
integrity of PE. One commenter suggested that ``to suppose a facility 
employee would break the law and jeopardize his license to practice his 
profession and do it more willingly than an ``independent'' engineer 
has no basis in fact'; (4) an in-house PE may be the person most 
familiar with the facility; (5) the proposal would place an undue and 
unnecessary financial burden on the owner or operator of a facility by 
forcing him to hire an outside engineer; and, (6) it is uncertain 
whether an independent PE can afford the insurance necessary to certify 
his work given that the liability incurred might run into the millions 
of dollars.
    Compromise position. One commenter suggested that a compromise 
position might be that the PE who certifies the Plan would be required 
to disclose in the Plan certification his relationship to the facility 
owner, the facility improvements owner, and the facility landowner.
    Response to comments. We agree that a proposal to restrict 
certification by a PE employed by a facility or having a financial 
interest in it would limit the availability of PEs, possibly leading to 
delays in Plan certification. Therefore, we will not adopt it. Nor do 
we favor the proposal to require the PE to disclose his relationship to 
the facility owner, the facility improvements owner, or the facility 
landowner. Such disclosure would add no environmental protection to the 
SPCC certification process. Administrative action to correct abuses 
would be a better approach. We believe that most PEs, whether 
independent or employees of a facility, being professionals, will 
uphold the integrity of their profession and only certify Plans that 
meet regulatory requirements. We also agree that an in-house PE may be 
the person most familiar with the facility. EPA believes that a 
restriction of in-house PE certification might place an undue and 
unnecessary financial burden on owners or operators of facilities by 
forcing them to hire an outside engineer.
3. Completion of Testing
    Background. The Agency proposed that the PE must attest that 
required testing has been completed and the Plan meets the requirements 
of the regulation for the facility. This proposal was advanced to 
``promote the Agency's intent in the original promulgation of 
Sec. 112.3(d) that SPCC Plans be certified by a Registered Professional 
Engineer exercising independent judgment.'' 56 FR 54619. These new 
requirements were to be met when a new Plan is prepared after 
promulgation of the rule, or when an existing Plan is amended, under 
Sec. 112.5.
    Comments. Favorable comments. One commenter supported a requirement 
that the PE attest to the completion of testing and that the Plan meets 
regulatory requirements.
    Opposing comments. Some opposing commenters believed that the PE 
should ``enumerate all the inspections and tests that have been 
completed, plus those that should be completed before the facility 
commences operations and those that should be undertaken periodically 
after it commences operations.'' Others believed that completion of 
required testing is the responsibility of the operator and not the PE. 
Another commenter believed such a requirement would be impossible, 
because ``required testing may take up to a year to complete.''
    Response to comments. EPA agrees that the PE is not responsible for 
certifying that all required testing has been completed. Rather, such 
responsibility belongs to the owner or operator of the facility. 
Testing may be ongoing long after the Plan is certified. The PE is 
responsible for certifying that the Plan is adequate and meets all 
regulatory requirements, including enumeration of all tests that have 
been

[[Page 47054]]

completed, plus those that should be completed before the facility 
commences operations and those that should be undertaken periodically 
after it commences operations. Therefore, we are changing the proposed 
requirement to a requirement in which the PE attests that the 
procedures for required inspections and testing have been established, 
and the Plan is adequate for the facility. See the discussion of 
Sec. 112.3(d), below.
4. Site Visits
    Background. We stated that EPA ``believes the current regulatory 
language (e.g., requiring the engineer to examine the facility) clearly 
requires the certifying Engineer to visit the facility prior to 
certifying the SPCC Plan.'' We added that the proposed change 
``clarifies this requirement by specifying that the Professional 
Engineer must be physically present to examine the facility.'' 56 FR 
54619.
    Comments. Favorable comments. Many commenters favored the 
requirement that the PE make a site visit prior to certifying a Plan. 
Those commenters called such a visit ``absolutely necessary.'' Some 
argued that a generic plan prepared by an engineer who has never seen 
the facility is unacceptable.
    Opposing comments. Opposing commenters asserted that such visits 
only involve additional costs and duplication of efforts without any 
tangible benefits. Many opposing commenters argued that customary 
engineering practice includes the use of engineering technicians, 
technologists, graduate engineers, and others to prepare preliminary 
reports, studies, and evaluations. After preparation of these 
documents, the PE would then perform a careful review of all pertinent 
material and then sign and seal the appropriate plans and drawings. 
Other commenters argued that such a requirement would be impractical, 
particularly at electrical substations, due to their large number.
    Particular cases. One commenter urged that small facilities be 
exempted from the site visit requirement where ``a determination is 
made that sufficient documentation of site characteristics is available 
for plan certification.'' That commenter noted that in many instances 
sufficient information is available from topographic maps, aerial 
photographs, soil surveys, hydrologic studies, engineering and 
construction reports, and local operating personnel to eliminate the 
need for site visits prior to certification. Another commenter urged an 
exemption for temporary storage facilities because given their 
emergency nature, certification is impractical. One commenter asked for 
clarification that the certification of an existing Plan is sufficient 
until the Plan update is required. Another suggested that the rule 
should only require that the PE be familiar with the operation and 
design of the type of facility, and that he would have visited and 
examined one or more facilities of this type.
    Response to comments. In general. EPA agrees that the rule should 
not necessarily require a site visit by a certifying PE, but we believe 
that a site visit should occur before the PE certifies the Plan. We 
have modified proposed Sec. 112.3(d)(ii) to reflect this position. The 
PE's agent may perform the visit. We agree that customary engineering 
practice allows someone under the PE's employ such as an engineering 
technician, technologist, graduate engineer, or other qualified person 
to prepare preliminary reports, studies, and evaluations after visiting 
the site. Then the PE could legitimately certify the Plan. 
Nevertheless, in all cases the PE must ensure that his certification 
represents an exercise of good engineering judgment. If that requires a 
personal site visit, the PE must visit the facility himself before 
certifying the Plan.
    Particular cases. EPA agrees that a PE site visit requirement might 
be impractical at electrical substations, due to their large number. 
However, the PE need not go. One of his agents may go, and he may 
review the agent's work. We disagree with commenters who believe that a 
site visit is unnecessary at small facilities and temporary storage 
facilities. Site visits are necessary for those facilities to ensure 
Plan adequacy and to prevent discharges.
    EPA has interpreted the current rule language to contain a 
requirement that the PE examine the facility. Because of the 
uncertainty concerning the nature of this requirement, however, we will 
not require documentation of a site visit by a PE or his agent until 
after the effective date of this rule. We disagree that the rule should 
only require that the PE be familiar with the operation and design of 
the type of facility. We also disagree that merely because the PE has 
visited and examined one or more facilities of a particular type that 
no site visit is necessary. A facility may have individual 
characteristics that differ from those of its type in general, and a 
site visit by a PE or agent may be necessary to detect those 
characteristics and accommodate them in the Plan. Such individual 
characteristics include geographic conditions, possible flow paths, 
facility design and construction, type of containers, product stored, 
particular equipment, and the integrity of containment at the facility. 
Therefore, even if a PE has inspected many facilities of a particular 
type, that fact does not eliminate the need for a site visit at each 
facility. After the site visit, the PE will have to devise appropriate 
inspection and testing standards based on the facility's unique 
characteristics.

E. Electrical Facilities and Other Operational Users of Oil

    Background. In 1991, we proposed that certain facilities having 
equipment containing oil that is used for operational purposes, such as 
electrical transformers, would not have to comply with secondary 
containment requirements and certain other provisions proposed in 
Secs. 112.8(c) and 112.9(d) because such facilities are not bulk 
storage facilities. EPA asked for comment on this and also asked 
commenters to identify other possible operational uses of oil, other 
than electrical transformers, that may not currently use secondary 
containment as a common industry practice and that should not be 
subject to bulk storage provisions. 56 FR 54623.
    Comments. Use of oil. Numerous commenters, especially in the 
electric utility industry, asserted that EPA has no jurisdiction to 
regulate the operational use of oil generally, or specifically in 
electrical transformers, substations, and other equipment. Some 
manufacturers of other products agreed. They argued that the 
legislative history of the Act showed no Congressional intent for such 
regulation. However, many commenters asked EPA specifically to clarify 
this jurisdictional issue.
    Response to comments. Use of oil. We disagree that operational 
equipment is not subject to the SPCC rule. We have amended 
Sec. 112.1(b) to clarify that using oil, for example operationally, may 
subject a facility to SPCC jurisdiction as long as the other 
applicability criteria apply, for example, oil storage capacity, or 
location. Such a facility might reasonably be expected to discharge oil 
as described in Sec. 112.1(b). Therefore, the prevention of discharges 
from such facility falls within the scope of the statute.
    However, we have distinguished the bulk storage of oil from the 
operational use of oil. We define ``bulk storage container'' in the 
final rule to mean any container used to store oil. The storage of oil 
may be prior to use, while being used, or prior to further distribution 
in commerce. For clarity, we have specifically excluded oil-filled 
electrical, operating, or manufacturing equipment from the definition.

[[Page 47055]]

    Facilities that use oil operationally include electrical 
substations, facilities containing electrical transformers, and certain 
hydraulic or manufacturing equipment. The requirements for bulk storage 
containers may not always apply to these facilities since the primary 
purpose of this equipment is not the storage of oil in bulk. Facilities 
with equipment containing oil for ancillary purposes are not required 
to provide the secondary containment required for bulk storage 
facilities (Sec. 112.8(c)) and onshore production facilities 
(Sec. 112.9(c)), nor implement the other provisions of Sec. 112.8(c) or 
Sec. 112.9(c). Oil-filled equipment must meet other SPCC requirements, 
for example, the general requirements of this part, including 
Sec. 112.7(c), to provide appropriate containment and/or diversionary 
structures to prevent discharged oil from reaching a navigable 
watercourse. The general requirement for secondary containment, which 
can be provided by various means including drainage systems, spill 
diversion ponds, etc., will provide for safety and also meet the needs 
of section 311(j)(1)(C) of the CWA. EPA will continue to evaluate 
whether the general secondary containment requirements found in 
Sec. 112.7(c) should be modified for small electrical and other types 
of equipment which use oil for operating purposes. We intend to publish 
a notice asking for additional data and comment on this issue.
    In addition, a facility may deviate from most SPCC requirements, if 
the owner or operator explains his reasons for nonconformance and 
provides equivalent environmental protection by some other means. See 
Sec. 112.7(a)(2). See also Sec. 112.7(d).

F. Discretionary Provisions

    Background. In the preamble to the 1991 proposal (at 56 FR 54616), 
we asked for comments as to whether the provisions proposed as 
recommendations in rule text should be made requirements. We then noted 
that we were ``particularly interested in receiving comments and 
information on the advisability of establishing'' certain provisions as 
``requirements for large facilities, but as recommendations for small 
facilities.'' These provisions were: (1) Proposed Sec. 112.8(d)(4)--
``that facilities have all buried piping tested for integrity and leaks 
annually or have buried piping monitored monthly in accordance with the 
provisions of 40 CFR part 280.'' We also recommended that records of 
testing or monitoring be kept for five years.; and, (2) proposed 
Sec. 112.8(d)(5)--``that facilities post vehicle weight restrictions to 
prevent damage to underground piping.'' Individual proposals will be 
discussed under their relevant sections in this preamble. Large 
facilities were defined for this purpose as facilities with more than 
42,000 gallons of SPCC-regulated storage capacity. Conversely, we asked 
whether such provisions should be discretionary for smaller facilities. 
The rationale expressed in the question was EPA believes that ``larger 
volumes of oil stored at a facility increase the chances of a spill 
occurring, and that spills from large-capacity facilities may be 
greater in magnitude than those from smaller facilities, thus posing a 
greater potential threat to the waters of the United States.''
    EPA also requested comments on two other practices it proposed as 
recommendations, but did not include in rule text. Those practices 
were: (1) ``That owners and operators of facilities affix a signed and 
dated statement to the SPCC Plan indicating that the revision has taken 
place and whether or not amendment of the Plan is required;'' and, (2) 
``That owners and operators of onshore facilities other than production 
facilities state the design capabilities of their drainage system in 
the SPCC Plan if the system is relied upon to control spills or 
leaks.'' Concerning the first practice, see also the discussion under 
Sec. 112.5(b) of today's rule. The rationale for these recommendations 
was that ``these provisions may not for all facilities achieve the 
standard of provisions based on good engineering practice, which is the 
basic standard of the regulation. EPA, however believes that 
implementation of these provisions at most facilities would contribute 
to the facilities' overall effort to prevent oil discharge and to 
mitigate those spills that may occur.'' The Agency also asked whether 
some of these provisions should be mandatory.
    Comments. Large or small facility regulation, in general. EPA 
received a number of comments on this issue, some directed towards 
regulation of larger and smaller facilities in general, and others 
toward specific provisions proposed. Some commenters believed that 
larger facilities could better bear the costs of regulation than 
smaller facilities, some of which were financially marginal and might 
go out of business as a result of environmental regulation.
    Storage capacity level. Commenters suggested different storage 
capacity levels at which to differentiate large from small facilities. 
Those suggestions ranged from 10,000 to 100,000 gallons in storage 
capacity. Many, however, supported the 42,000-gallon level.
    Other factors. One commenter suggested that other factors such as 
proximity to navigable waters or environmentally sensitive areas, as 
well as the use of good engineering practices should be considered in 
the regulation of facilities. The commenter argues that these factors 
might avoid overburdening a large facility with a low potential for 
impact on a navigable water or exempting a small facility with a high 
potential for impact on a navigable water.
    Discretionary provisions. Favorable commenters. Numerous commenters 
favored discretionary provisions in the interest of maintaining 
flexibility in the program, noting that what may be appropriate for one 
facility may not be appropriate for another. Some commenters favored 
applying discretionary provisions to small facilities only, leaving the 
provisions as requirements for larger facilities.
    Discretionary provisions. Opposing commenters. Some commenters 
argued that discretionary provisions are inappropriate in a rule as a 
matter of principle because they complicate mandatory rule documents 
and enforcement, and they confuse the regulated community. Yet others 
urged that such provisions were unnecessary in any case because they 
believe that no risks exist for which the discretionary provisions were 
proposed.
    Response to comments. We will discuss specific comments under the 
discussion of specific sections. See section IV.G of today's preamble 
for a discussion of the ``Design Capabilities of Drainage Systems, 
other than Production Facilities.'' Our general discussion follows.
    Large or small facility regulation, in general. We have decided not 
to regulate facilities differently based merely on storage capacity, 
provided that the capacity is above the regulatory threshold of over 
1,320 gallons. This decision is based on environmental reasons. Small 
discharges of oil that reach the environment can cause significant 
harm. Sensitive environments, such as areas with diverse and/or 
protected flora and fauna, are vulnerable to small spills. EPA noted in 
a recent denial of a petition for rulemaking: ``Small spills of 
petroleum and vegetable oils and animal fats can cause significant 
environmental damage. Real-world examples of oil spills demonstrate 
that spills of petroleum oils and vegetable oils and animal fats do 
occur and produce deleterious environmental effects. In some cases, 
small spills of vegetable oils can produce more environmental harm than 
numerous large spills of petroleum

[[Page 47056]]

oils.'' 62 FR 54508, 54530, October 20, 1997. Describing the outcome of 
one small spill of 400 gallons of rapeseed oil into Vancouver Harbor, 
we noted that `` * * * 88 oiled birds of 14 species were recovered 
after the spill, and half of them were dead. Oiled birds usually are 
not recovered for 3 days after a spill, when they become weakened 
enough to be captured. Of the survivors, half died during treatment. 
The number of casualties from the rapeseed oil spills was probably 
higher than the number of birds recovered, because heavily oiled birds 
sink and dying or dead birds are captured quickly by raptors and 
scavengers.'' 62 FR 54525.
    A small discharge may also cause harm to human health or life 
through threat of fire or explosion, or short-or long-term exposure to 
toxic components.
    Other factors. Finally, EPA notes that the rule affords flexibility 
to an owner or operator of a facility to design a Plan based on his 
specific circumstances. It allows him to choose methods that best 
protect the environment. It permits deviations from most of the 
mandatory substantive requirements of the rule when the facility owner 
or operator can demonstrate a reason for nonconformance, and can 
provide equivalent environmental protection by other means. 
Consequently, both small and large facilities have the opportunity to 
reduce costs by alternative methods if they can maintain environmental 
protection. Because smaller facilities may require less complex plans 
than larger ones, their costs may be less.
    Discretionary provisions. We agree that discretionary provisions 
have no place in this rule because we do not wish to confuse the 
regulated community and complicate enforcement by blurring what is 
mandatory and what is discretionary. We will provide guidance or policy 
statements on various issues, as necessary, that will incorporate some 
or all of these recommendations. In the absence of such guidance or 
policy statements, you should look to current industry standards for 
guidance on technical issues. See also our discussion of industry 
standards and good engineering practice under section IV.K of today's 
preamble and under Sec. 112.3(d) in section V of today's preamble.

G. Design Capabilities of Drainage Systems, Other than Production 
Facilities

    Background. In the 1991 preamble, we asked for comments on, but did 
not propose, a provision that owners or operators of onshore facilities 
other than production facilities describe the design capabilities of 
their drainage systems in the SPCC Plan if the system is relied upon to 
control spills or leaks. 56 FR 54616, October 22, 1991. See also 
section IV.F of today's preamble for a discussion of other 
``Discretionary Provisions.''
    Comments. Favorable comments. Commenters favoring such a 
requirement asserted that such a description would help identify all 
paths of escape for discharges at a facility, assess the spill 
retention capacity of the facility's containment system, and identify 
the risks to the public of a discharge. Those commenters generally 
believed that the Professional Engineer should develop the description 
for the Plan.
    Opposing comments. Commenters opposing making the recommendation a 
requirement argued that it was unnecessary because the rules already 
require certain descriptions of design capabilities of drainage 
systems. They asserted that such a requirement would be redundant in 
that if a drainage system is relied upon to control spills or leaks, 
then it must have design capabilities to control such spills or leaks.
    Response to comments. The question of description of the design 
capabilities of drainage systems for onshore facilities other than 
production facilities is adequately covered by rules pertaining to 
drainage. See, for example, Secs. 112.7(a)(3) and (4), 112.7(b), 
112.8(b), and 112.10(c). Therefore, we will not promulgate any 
additional requirements on this subject. These provisions generally 
require that a facility owner or operator design the facility drainage 
system to prevent discharges, or if prevention fails, to contain the 
discharge within the facility.

H. Compliance Costs

    Background. We provided an extensive discussion of the costs and 
benefits of the proposed 1991 rule. 56 FR 54628-54629, October 22, 
1991. We requested comments in the 1991 preamble concerning the new 
compliance costs associated with the proposed rule.
    Comments. EPA received numerous comments on this issue. The 
overwhelming majority of commenters asserted that the proposed rule 
would impose costs that few could bear. Many argued that such costs 
were unnecessary or should be applied to large facilities only.
    Response to comments. EPA considered cost factors in finalizing the 
requirements in this rule. We believe that facilities in compliance 
with the current rule will incur minimal additional cost due to the 
revisions in this rule. Many of the provisions we proposed in 1991 that 
commenters believed were too costly were not finalized in this rule. In 
addition, in today's rule, we have provided flexibility in several 
ways. Many of the provisions we proposed in 1991 that commenters 
believed were too costly were not finalized in this rule. In addition, 
in the deviation provision, Sec. 112.7(a)(2), we permit you to 
substitute alternate measures that provide equivalent environmental 
protection if you can explain a reason for nonconformance with the 
prescribed requirement. We also rely on the use of industry standards 
in many provisions, rather than mandating any particular procedure, or 
any particular monitoring or inspection schedule. We assume that most 
facilities follow industry standards, and therefore will not incur 
additional costs for many provisions where they do. We recognize, 
however, that to the extent any facility does not follow current 
industry standards, it might incur additional costs. Furthermore, we 
are finalizing other provisions in this rule which will reduce burden 
in other ways and will exempt certain facilities from having to prepare 
an SPCC or FRP Plan. EPA has also prepared an assessment of the costs 
of rule compliance, which is discussed in part VI.F (Regulatory 
Flexibility Act) of this preamble, and we have included the specific 
comments related to costs and our responses in relevant sections of 
this preamble.

I. Contingency Planning and Notification

    Background. We requested comments in the 1991 preamble on spill 
contingency planning needs (at 56 FR 54615) and on proposed facility 
notification requirements (at 56 FR 54614). You will find a detailed 
discussion of contingency requirements and facility notification 
requirements (Sec. 112.7(d) and proposed Sec. 112.1(e)) in Section V of 
today's preamble. On those subjects, we briefly summarize the comments 
and our responses below.
    Comments. Contingency planning. Many commenters supported the 1991 
proposal. Opposing commenters suggested that such planning should be 
discretionary because not all facilities need such planning, or that 
facilities be allowed to use contingency plans prepared for other 
purposes. Others thought the proposal was premature as we had not at 
the time finalized response planning requirements in Sec. 112.20. Some 
said that contingency planning was not practicable because

[[Page 47057]]

the costs are too high, but these commenters did not provide specific 
cost estimates.
    Notification. A number of commenters favored the proposal, 
including some industry commenters. Most industry commenters opposed 
the proposal either in part or in its entirety. Commenters who opposed 
the proposal in its entirety asserted that it was unnecessary, largely 
because they believed the information sought might be better obtained 
from other sources, such as State sources or SARA Title III reports.
    Response to comments. Contingency planning. Contingency planning is 
necessary whenever you determine that a secondary containment system 
for any part of the facility that might be the cause of a discharge as 
described in Sec. 112.1(b) is not practicable. This requirement applies 
whether the facility is manned or unmanned, urban or rural, and for 
large and small facilities. Because we have not finalized either the 
1991 or 1993 contingency plan proposals, there are no new costs. We 
note that we finalized response planning requirements in 1994. 
Contingency plans prepared for other purposes are acceptable for SPCC 
purposes if they satisfy all SPCC requirements.
    Notification. Withdrawal of proposal. We have decided to withdraw 
the proposed facility notification requirement because we are still 
considering issues associated with establishing a paper versus 
electronic notification system, including issues related to providing 
electronic signatures on the notification. Should the Agency in the 
future decide to move forward with a facility notification requirement, 
we will repropose such requirement.

J. Reproposal

    Background: In the 1997 proposal, we stated that we would finalize 
the 1991 and 1993 proposals without seeking additional comments on 
those proposals.
    Comments: Some commenters suggested that we repropose the 1991 
proposal ``so that the public can view the proposed changes in a 
comprehensive manner.'' Other commenters suggested that the time that 
has elapsed, the changes in operational procedures of the oil and gas 
industry which have improved the degree of environmental protection, 
and the new information EPA obtained from its tank survey, justified 
reproposal. Others cited changes in oil industry personnel as a reason 
to repropose the rule. Some commenters believed that the implementation 
of the Facility Response Plan (FRP) rule alone requires us to solicit 
additional comments concerning the SPCC proposals.
    Response: Additional comments or reproposal. We believe it is 
unnecessary to repropose the 1991 and 1993 proposals because of mere 
passage of time. We received numerous comments on every side of most 
issues. In developing this final rule, we have considered changes that 
have taken place in the oil industry, industry standards, and 
regulations that may affect the SPCC rule. We have also considered 
changes in the various industries which comprise the universe of SPCC 
facilities which have occurred since our original proposals. We 
encourage the use of industry standards to implement the rule, without 
incorporating any particular standard into the rule, thereby averting 
possible obsolescence of those standards. We used the results of our 
1995 SPCC facility survey to develop our 1997 proposed rule. These 
results are also part of the administrative record for this rulemaking. 
We considered all the comments we received in 1997, even if they dealt 
with issues proposed in 1991 or 1993. We have also considered and 
responded to all of the comments received in 1991 and 1993 in their 
respective Comment Response Documents or in the preamble to today's 
final rule.
    Personnel changes. In developing this final rule, as noted above, 
we have considered changes that have taken place in the oil industry, 
industry standards, and regulations that may affect the SPCC rule. For 
the past 26 years, owners and operators of regulated facilities have 
been responsible for training their personnel in applicable 
regulations, such as 40 CFR part 112. Such responsibility is in effect 
now, and will continue under the revised rule. New companies and new 
personnel of those companies are on notice as to applicable rules and 
proposals. They have also had the opportunity to comment on the 1997 
proposal. Furthermore, we have considered cost implications for all 
three proposals which we are finalizing today.
    Response plan requirements. We have no plans to require SPCC 
facilities for which secondary containment is not practicable to 
develop response plans. However, we have withdrawn Sec. 112.7(d) as 
proposed in 1993. Only a contingency plan following the provisions of 
40 CFR part 109 and compliance with other provisions of Sec. 112.7(d) 
is necessary when secondary containment is impracticable. Only onshore 
facilities that meet the criteria of substantial harm and/or 
significant and substantial harm facilities need to comply with the FRP 
requirements in 40 CFR 112.20-21.

K. Industry Standards

    Throughout the rule we generally allow for the application of 
industry standards where the standards are both specific and objective, 
and their application may reduce the risk of discharges to and impacts 
to the environment. We recognize that as technology advances, specific 
standards change. By referencing industry standards throughout the 
preamble, we anticipate that the underlying requirements of the rule 
itself will change as new technology comes into use without the need 
for further amendments. We believe that industry standards today 
represent good engineering practice and generally are environmentally 
protective. However, as under the current rule, if an industry standard 
changes in a way that would increase the risk of a discharge as 
described in Sec. 112.1(b), EPA will apply and enforce standards and 
practices that protect the environment, rather than the less protective 
industry standard.
    Under the terms of this rule, when there is no specific and 
objective industry standard that applies to your facility (for example, 
whether there is no standard or a standard that uses the terms ``as 
appropriate,'' ``often,'' ``periodically,'' and so forth), you should 
instead follow any specific and objective manufacturer's instructions 
for the use and maintenance or installation of the equipment, 
appurtenance, or container. If there is neither a specific and 
objective industry standard nor a specific and objective manufacturer's 
instruction that applies, then it is the duty of the PE under 
Sec. 112.3(d) to establish such specific and objective standards for 
the facility and, under Sec. 112.3(d), he must document these standards 
in the Plan. If the PE requires the use of a specific standard for 
implementation of the Plan, the owner or operator must also reference 
that standard in the Plan.
    Throughout this preamble, we list industry standards that may 
assist an owner or operator to comply with particular rules. The list 
of those standards is merely for your information. They may or may not 
apply to your facility, but we believe that their inclusion is helpful 
because they generally are applicable to the topic referenced. The 
decision in every case as to the applicability of any industry standard 
will be one for the PE.
    For your convenience, we are including a list of organizations 
below

that may be helpful in the identification and explanation of industry 
standards.

V. Section by Section Analysis (Includes: Background, Comments, and 
Response to Comments)

Subpart A--Applicability, definitions, and general requirements for all 
facilities

    Background. In the reformatted rule, subpart A defines the 
applicability of part 112, provides definitions applicable to all 
subparts, and prescribes general requirements that are applicable to 
all facilities subject to part 112.

Section 112.1(a)(1)--General Applicability of the Rule

    Background. We have redesignated Sec. 112.1(a) as Sec. 112.1(a)(1) 
due to the addition of a new paragraph (a)(2). In 1991, we proposed 
changes in Sec. 112.1(a) to conform to the 1977 CWA amendments. Those 
amendments extended the geographic scope of EPA's authority under CWA 
section 311. Formerly the geographic scope of the rule extended only to 
navigable waters of the United States and adjoining shorelines. The 
final rule extends the geographic scope of EPA's authority beyond 
discharges to navigable waters and adjoining shorelines to include a 
discharge into or upon the waters of the contiguous zone, or in 
connection with activities under the Outer Continental Shelf Lands Act 
or the Deepwater Port Act of 1974, or that may affect natural resources 
belonging to, appertaining to, or under the exclusive management 
authority of the United States (including resources under the Magnuson 
Fishery

[[Page 47059]]

Conservation and Management Act). Hereinafter, a discharge as described 
above in quantities that may be harmful is also referred to as ``a 
discharge as described in Sec. 112.1(b).''
    Comments. Geographic scope of rule. One commenter wrote to support 
the geographic extension of the rule, noting that the extended 
definition ``will allow for more clarity in determining which 
facilities are subject to SPCC requirements.''
    Natural resources. Another commenter was concerned that the 
extension of the rule to facilities with the potential to affect 
natural resources ``would bring under the scope of 40 CFR 112 a 
significant number of operating facilities which did not previously 
require SPCC plans.'' Still another commenter proposed limiting the 
scope of natural resource jurisdiction under the rule to resources 
under the Magnuson Fishery and Conservation Act to avoid ``another 
unnecessary workload on the judicial system over the years.''
    Response to comments. Geographic scope of rule. EPA believes that 
the geographic extension of the rule to agree with statutory amendments 
is the proper course, and has finalized the rule as proposed.
    Natural resources. Limiting the scope of natural resource 
jurisdiction under the rule to natural resources under the Magnuson 
Fishery Conservation and Management Act would be inconsistent with this 
statutory language. We also believe that few, if any new facilities, 
will be subject to the rule because of its extension to facilities with 
the potential to affect certain natural resources. We believe that most 
affected facilities are either already subject to the rule, or not 
subject to our jurisdiction due to a Memorandum of Understanding 
between EPA, the U.S. Department of Transportation (DOT), and the U.S. 
Department of the Interior (DOI), which assigns jurisdiction over most 
of those facilities to DOT or DOI. See 40 CFR part 112, Appendix B.
    Editorial changes and clarifications. While revisions to the rule 
published today are not retroactive, any violation of the current rule 
which occurs before the effective date of today's rule is subject to 
enforcement and penalties.

Section 112.1(a)(2)--Number and Gender

    Background. We added a new Sec. 112.1(a)(2) to make clear that 
words in the singular include the plural, and words in the masculine 
include the feminine, and vice versa. This amendment is for 
clarification purposes only.

Section 112.1(b)--Facilities Covered by the Rule--Non-Transportation-
Related Facilities

    Background. We have redesignated this section to add four new 
paragraphs. This section describes generally the type of facilities 
which are subject to the SPCC rule.
    In 1991, EPA proposed changes in Sec. 112.1(b) to reflect changes 
in the geographic scope of EPA's authority under CWA section 311, as 
described in the discussion under Sec. 112.1(a)(1). EPA also proposed 
to change the phrase ``harmful quantities'' to ``quantities that may be 
harmful, as described in part 110.'' Amendments to the CWA also 
reflected the broadening of quantities that may be harmful to include 
those not only harmful to the ``public health or welfare,'' but also to 
the environment.
    Comments. Facilities. Several commenters argued that EPA 
jurisdiction, under statutory authority, does not extend to facilities, 
merely to requirements for oil spill prevention and containment 
equipment. The commenters' argument noted that the statute doesn't 
mention jurisdictional criteria relating to proximity to water or oil 
storage capacity, only EPA rules do. Therefore, the commenters argued, 
if EPA is successful in its assertion of facility regulation, then 
every pipe, valve, meter, and flange on the wellsite along with tubing 
and casing in the hole, stock tanks, drainage ditches, and roads are 
all subject to EPA jurisdiction and specifications. More importantly, 
they argued, every facility, in every industry, which at some time or 
other handles oil or hazardous substances could be subject to EPA rules 
concerning its spill prevention and containment procedures, methods, or 
equipment.
    Use of oil. Numerous commenters, especially in the electric utility 
industry, asserted that EPA has no jurisdiction to regulate the 
operational use of oil generally, or specifically in electrical 
transformers, substations, and other equipment. Some manufacturers of 
other products agreed. They argued that the legislative history of the 
Act showed no Congressional intent for such regulation. However, many 
commenters asked EPA specifically to clarify this jurisdictional issue.
    Distance to navigable waters. Two commenters proposed that we 
exempt from the rule facilities more than one mile from surface waters 
or those located outside the coastal zone.
    Response to Comments: Facilities. We disagree that our authority 
does not extend to facilities. Section 311(j)(1)(C) of the statute 
authorizes and requires the President (and EPA, through delegation in 
Executive Order 12777, 56 FR 54757, October 22, 1991) to issue 
regulations consistent with the National Oil and Hazardous Substances 
Pollution Contingency Plan, and consistent with maritime safety and 
with marine and navigation laws, which establish ``procedures, methods, 
and equipment and other requirements for equipment to prevent 
discharges of oil and hazardous substances from vessels and from 
onshore and offshore facilities, and to contain such discharges.'' This 
language authorizes the President to issue oil spill prevention rules 
which pertain to onshore facilities and offshore facilities and not 
just ``equipment.''
    In order to fulfill the statutory mandate, it is necessary to 
regulate the facilities from which discharges emanate. Moreover, 
although the term ``facility'' is not defined in the statute, both 
``onshore facility'' and ``offshore facility'' are defined terms in CWA 
section 311. They have also been defined terms in the SPCC rule since 
its inception in 1974. In the 1991 proposal, EPA proposed a definition 
of ``facility'' to implement the CWA. That definition was based on a 
Memorandum of Understanding (MOU) between the Secretary of 
Transportation and the EPA Administrator dated November 24, 1971 (36 FR 
24080). The MOU, which has been published as Appendix A to part 112 
since December 11, 1973 (38 FR 34164, 34170), defines in detail what 
constitutes a facility. Thus, there has long been a common 
understanding of the term. That understanding has been reinforced by 
frequent use of the term in context within the SPCC rule since it 
became effective in 1974. To promote clarity and to maintain all 
definitions in one place, the proposed definition has been finalized in 
this rulemaking.
    While section 311(j)(1)(C) of the Act may not explicitly mention 
jurisdictional criteria, section 311(b) of the Act does. Section 311(b) 
establishes as the policy of the United States that there shall be ``no 
discharges of oil or hazardous substances into or upon the navigable 
waters of the United States, adjoining shorelines, or into or upon the 
waters of the contiguous zone, or in connection with activities under 
the Outer Continental Shelf Lands Act or the Deepwater Port Act of 
1974, or which may affect natural resources belonging to, appertaining 
to, or under the exclusive management authority of the United States 
(including resources under the Magnuson Fishery Conservation and 
Management Act).'' Thus, the location or ``jurisdictional'' criteria 
contained in Sec. 112.1(b) are appropriate for inclusion in the rule.

[[Page 47060]]

    Use of oil. We disagree that operational equipment is not subject 
to the SPCC rule. We have amended Sec. 112.1(b) to clarify that using 
oil, for example operationally, may subject a facility to SPCC 
jurisdiction as long as the other applicability criteria apply, for 
example, oil storage capacity, or location. Such a facility might 
reasonably be expected to discharge oil as described in Sec. 112.1(b). 
Therefore, the prevention of discharges from such facility falls within 
the scope of the statute.
    However, we have distinguished the bulk storage of oil from the 
operational use of oil. We define ``bulk storage container'' in the 
final rule to mean any container used to store oil. The storage of oil 
may be prior to use, while being used, or prior to further distribution 
in commerce. For clarity, we have specifically excluded oil-filled 
electrical, operating, or manufacturing equipment from the definition.
    Facilities that use oil operationally include electrical 
substations, facilities containing electrical transformers, and certain 
hydraulic or manufacturing equipment. The requirements for bulk storage 
containers may not always apply to these facilities since the primary 
purpose of this equipment is not the storage of oil in bulk. Facilities 
with equipment containing oil for ancillary purposes are not required 
to provide the secondary containment required for bulk storage 
facilities (Sec. 112.8(c)) and onshore production facilities 
(Sec. 112.9(c)), nor implement the other provisions of Sec. 112.8(c) or 
Sec. 112.9(c). Oil-filled equipment must meet other SPCC requirements, 
for example, the general requirements of this part, including 
Sec. 112.7(c), to provide appropriate containment and/or diversionary 
structures to prevent discharged oil from reaching a navigable 
watercourse. The general requirement for secondary containment, which 
can be provided by various means including drainage systems, spill 
diversion ponds, etc., will provide for safety and also the needs of 
section 311(j)(1)(C) of the CWA.
    In addition, a facility may deviate from any inappropriate SPCC 
requirements, if the owner or operator explains his reasons for 
nonconformance and provides equivalent environmental protection by some 
other means. See Sec. 112.7(a)(2). See also Sec. 112.7(d).
    Distance to navigable waters. We do not believe that any rule which 
exempts facilities beyond any particular distance meets the intent of 
the statute. The locational standard in the rule is whether there is a 
reasonable possibility of discharge in quantities that may be harmful 
from the facility. A facility that is more than one mile from navigable 
waters might well fit within that standard. For example, piping or 
drainage from that facility might lead directly to navigable water. If 
discharged oil may reach or does reach navigable waters, adjoining 
shorelines, or protected resources, the distance which the discharged 
oil travels is irrelevant.
    Editorial changes and clarifications. In the proposed rule, this 
paragraph was designated as Secs. 112.1(b) and 112.1(b)(1). We have 
combined the paragraphs and added two new paragraphs. The new 
paragraphs describe the types of containers subject to the rule, which 
in addition to the two paragraphs we already proposed, better describe 
those containers. We also changed plural references in the proposal to 
singular throughout the section.

Section 112.1(b)(1)--Aboveground Storage Containers

    Background. We added this paragraph to clarify that aboveground 
storage containers are a subset of the containers subject to the rule. 
In 1991, we noted that containers used for standby storage, temporary 
storage, or containers that are not permanently closed, are subject to 
the rule. We also noted that bunkered tanks and partially buried tanks 
are subject to the rule. The inclusion of this paragraph and paragraph 
(b)(2), which refers to completely buried tanks, completes the universe 
of containers subject to the rule.

Section 112.1(b)(2)--Completely Buried Tanks

    Background. We added this paragraph to clarify that completely 
buried tanks are a subset of the containers subject to the rule. See 
also the discussion under Sec. 112.1(b)(1).

Section 112.1(b)(3)--Standby, Temporary, or Seasonal Storage Facilities

    Background. We proposed in 1991 to clarify that tanks used for 
standby, temporary, or seasonal storage, or that are not otherwise 
permanently closed, are subject to the SPCC rule. The Agency noted that 
such tanks are not permanently closed and can reasonably be expected to 
experience a discharge as described in Sec. 112.1(b). 56 FR 54617. The 
facilities described in Sec. 112.1(b)(3) are a subset of the facilities 
described in Sec. 112.1(b)(1) and (b)(2).
    Comments. One commenter asserted that temporarily closed tanks 
should be exempted from the rules because they are required to be 
drained and, while awaiting temporary closure, are no threat to the 
environment through oil spills. Another commenter urged that temporary 
storage facilities should be exempted from the SPCC rule, and handled 
under the Facility Response Plan (FRP) rules, found at 40 CFR 112.20-
21. A third commenter argued that frac tanks, used to store oil for the 
short periods of time while maintenance or workover operations are 
underway, should be exempted from the rule because their use is of 
short duration and does not necessarily increase the potential for 
discharge. Another commenter stated that it would be impractical to 
maintain an up-to-date SPCC Plan for temporary storage at remote parts 
of a large mining operation.
    Response to comments. If a tank is not permanently closed, it is 
still available for storage and the possibility of a discharge as 
described in Sec. 112.1(b), remains. Nor does a short time period of 
storage eliminate the possibility of such a discharge. Therefore, a 
prevention plan is necessary. A tank closed for a temporary period of 
time may contain oil mixed with sludge or residues of product which 
could be discharged. Discharges from these facilities could cause 
severe environmental damage during such temporary storage and are 
therefore subject to the rule. As to the argument that it is 
impractical to maintain an up-to-date Plan for temporary facilities at 
remote parts of mining sites, we disagree. Plans for such storage are 
analogous to or may be Plans for mobile facilities, which may be 
general Plans, but still provide environmental protection against a 
discharge as described in Sec. 112.1(b).
    Editorial changes and clarifications. In the proposed rule, this 
paragraph was designated as Sec. 112.1(b)(2). We have redesignated it 
as Sec. 112.1(b)(3).

Section 112.1(b)(4)--Bunkered, Partially Buried, and Vaulted Tanks

    Background. In 1991, we proposed to clarify that bunkered tanks, 
partially buried tanks, and tanks in subterranean vaults are considered 
aboveground tanks for purposes of the SPCC rule. The tanks or 
containers in these facilities are a subset of the facilities described 
in Sec. 112.1(b)(1). The Agency explained that compared to completely 
buried tanks, discharges from these tanks are more likely to enter 
surface waters regulated under the CWA. 56 FR 54626.
    Comments. Partially buried and bunkered tanks. A commenter 
suggested that partially buried and bunkered tanks should be considered 
underground storage tanks (USTs) and regulated under that program 
because ten percent

[[Page 47061]]

or more of the product is below grade either in the tank or in the 
pipeline. The commenter argued that tanks in compliance with the UST 
program, found at 40 CFR part 280, would not pose a significant threat 
to the environment. In fact, the commenter argued, they might be less 
likely to cause a spill than one in compliance with the SPCC rule. The 
commenter further argued that dual regulation would be unnecessarily 
burdensome without providing any additional environmental protection.
    Vaulted tanks. Several commenters asserted that since vaulted tanks 
are already regulated by fire and safety authorities, they should not 
be regulated under the SPCC program. Others argued that vaulted tanks 
meeting the technical requirements of 40 CFR part 280, or which have 
engineering controls designed to contain product released from failure 
or overfill, should likewise be exempted from the SPCC rule. These 
commenters asserted that a discharge from such tanks would not reach 
water.
    Response to comments. Partially buried and bunkered tanks. We 
disagree that partially buried tanks and bunkered tanks should be 
considered completely buried tanks, and therefore excluded from SPCC 
provisions. The rules differ in important aspects. Tanks which are 
partially underground pose a risk of a discharge as described in 
Sec. 112.1(b), which could have an adverse impact on navigable water, 
adjoining shorelines, or affected resources. Some tanks that are not 
completely buried contain engineering controls designed to prevent 
discharges. However, such controls may fail due to human or mechanical 
error and cause severe environmental damage. Such tanks may suffer 
damage caused by differential corrosion of buried and non-buried 
surfaces greater than completely buried tanks, which could cause a 
discharge as described in Sec. 112.1(b).
    Such tanks are also not subject to secondary containment 
requirements under part 280 or a State program approved under 40 CFR 
part 281. There may also be accidents during loading or unloading 
operations, or overfills resulting in a discharge to navigable waters 
and adjoining shorelines. Furthermore, a failure of such a tank (caused 
by accident or vandalism) would be more likely to cause a discharge as 
described in Sec. 112.1(b). We will, however, accept UST program forms, 
e.g., the Notification for Underground Storage Tanks, EPA Form 7530-1, 
or approved State program equivalents, insofar as such forms contains 
information relevant to the SPCC program. For example, the UST form 
(item 12) contains information regarding corrosion protection for steel 
tanks and steel piping which would be relevant for SPCC purposes. Other 
items on the form may also be relevant for SPCC purposes. We are, 
however, excluding from the rule completely buried storage tanks 
(including connected underground piping, underground ancillary 
equipment, and containment systems) that are currently subject to all 
of the technical requirements of 40 CFR part 280 or 281. See 
Sec. 112.1(d)(4).
    Vaulted tanks. Vaulted tanks are generally excluded from the scope 
of 40 CFR part 280. The definition of ``underground storage tank'' at 
40 CFR 280.12(i) excludes from its scope a ``storage tank situated in 
an underground area (such as a basement, cellar, mineworking, drift, 
shaft, or tunnel) if the storage tank is situated upon or above the 
surface of the floor.'' These tanks might reasonably experience a 
discharge as described in Sec. 112.1(b). Therefore, it is reasonable 
that they be within the scope of part 112. Merely because these tanks 
are the subject of local fire and safety regulations does not guarantee 
that there will be adequate environmental protection to prevent a 
discharge as described in Sec. 112.1(b), because that is not the 
purpose of those regulations. Such codes may provide lesser protection 
than part 112. For example, NFPA 30:2-3.4.3(b) specifically indicates 
that a dike need only provide containment for the largest tank, while 
part 112 requires freeboard for precipitation.
    Editorial changes and clarifications. In the proposed rule, this 
paragraph was designated as Sec. 112.1(b)(3). We have redesignated it 
as Sec. 112.1(b)(4). Section 112.1(b)(3) of the proposed rule uses the 
term ``aboveground storage containers,'' in place of ``aboveground 
storage tanks.'' See 56 FR 54630. We continue to use ``containers'' in 
the final rule. We deleted the word ``subterranean,'' which modified 
vaulted tanks in the proposed rule, because vaulted tanks are 
considered aboveground tanks under this rule whether they are 
subterranean or not.

Section 112.1(c)--Federal Agencies--Applicability of Rule

    Background. In 1991, we republished the already existing provisions 
of Sec. 112.1(c), which provide that agencies, departments, and 
instrumentalities of the Federal government are subject to the rule to 
the same extent as any person, except for the provisions relating to 
civil penalties. The provision relating to civil penalties was 
rescinded on March 11, 1996, because it no longer accurately reflected 
the penalties provided for under section 311(b) of the Act, as amended 
by OPA. 61 FR 9646. Therefore, we have reserved Sec. 112.6 for future 
use.
    Comments. One commenter suggested that Federal agencies are subject 
to civil penalties which are imposed under the CWA--including fines.
    Response to comments. EPA disagrees that Federal agencies are 
subject to penalties or fines under the CWA because the Federal 
government is not a ``person'' under sections 311(a)(7) or 502 of the 
CWA. Only ``persons'' (including owners or operators and persons in 
charge) are subject to such penalties. Therefore, although Federal 
agencies must comply with requirements of a CWA section 311 rule in 
accordance with CWA section 313, they are not subject to civil or 
criminal penalties or fines. See U.S. Department of Energy v. Ohio, 503 
U.S. 607, 618 (1992) (because the CWA does not define ``person'' to 
include the United States, the civil penalty provisions are not 
applicable).

Section 112.1(d)--Exemptions From Applicability

Section 112.1(d)(1)--Exemptions Based on Jurisdiction

Section 112.1(d)(1)(i)--Exemptions Based on Location

    Background. In 1991, we described the facilities, equipment, and 
operations that are exempt from the SPCC rule because they are not 
subject to the jurisdiction of EPA under section 311(j)(1)(C) of the 
Act. These facilities include those which, due to their location, could 
not be reasonably expected to have a discharge as described in 
Sec. 112.1(b).
    In making the determination of whether there is a reasonable 
possibility of a discharge as described in Sec. 112.1(b), we proposed 
that you may consider only the geographical and locational aspects of 
the facility (such as proximity to navigable waters or adjoining 
shorelines, land contour, drainage, etc.). We proposed that you could 
not consider manmade structures such as dikes, equipment, or other 
structures which may serve to restrain, hinder, or otherwise contain a 
discharge as described in Sec. 112.1(b), in making that same 
determination.
    Comments. Geographic scope of rule. One commenter agreed that the 
extension of the geographic scope of the rule will allow for more 
clarity in determining which facilities are subject to SPCC 
requirements. The commenter added that the inclusion of natural

[[Page 47062]]

resources sets the stage for the implementation of Natural Resource 
Damage Assessments, as required by the Oil Pollution Act of 1990.
    Manmade structures. Other commenters argued that EPA should modify 
its rules to provide that a facility with no reasonable possibility of 
discharge because of some combination of natural and manmade features, 
which are present for operational rather than pollution prevention 
purposes, should be excluded from the scope of the rule. Another 
commenter urged that the rule allow consideration of manmade structures 
where the structures are inherent in the design of the facility and 
serve functional and operational purposes distinct from the containment 
of oil spills.
    Groundwater. Another commenter argued that Congress intended for 
EPA to develop SPCC requirements that prevent releases to groundwater, 
in addition to requirements that prevent releases to navigable water. 
At a minimum, that commenter argued, Sec. 112.1(d)(1)(i) should contain 
language stating that clear hydrologic connections between groundwater 
underlying a facility and navigable waters require a facility to 
develop and implement an SPCC Plan. Yet another commenter, in opposing 
exemption of USTs from the SPCC program noted that groundwater 
eventually becomes surface water. The commenter added that, 
hydrologically, oil released into underground waters may migrate to 
surface water within minutes or months. The commenter argued that in 
the absence of emergency response provisions, some USTs could damage 
the nation's ground and surface water resources.
    Response to comments. Geographic scope of rule. We also believe 
that few, if any, new facilities will be subject to the rule because of 
its extension to facilities with the potential to affect certain 
natural resources. We believe that most affected facilities are either 
already subject to the rule, or not subject to our jurisdiction due to 
a Memorandum of Understanding between EPA, the U.S. Department of 
Transportation (DOT), and the U.S. Department of the Interior (DOI), 
which assigns jurisdiction over most of those facilities to DOT or DOI. 
See 40 CFR part 112, Appendix B.
    We have amended this provision to be consistent with the revised 
statutory language found in sections 311(b)(1) and (c)(1)(A) of the 
CWA. This rule focuses on preventing discharges to navigable waters, 
adjoining shorelines, the exclusive economic zone, and natural 
resources belonging to, appertaining to, or under the exclusive 
jurisdiction of the United States. Once a prohibited discharge of oil 
occurs and affects such natural resources, the NRDA provisions of OPA 
sections 1002(b)(2)(A) and 1006 apply. The National Oceanographic and 
Atmospheric Administration has promulgated a set of regulations which 
govern the process for conducting NRDAs under the OPA. 15 CFR part 990.
    Manmade structures. To allow consideration of manmade structures 
(such as dikes, equipment, or other structures) to relieve a facility 
from being subject to the rule would defeat its preventive purpose. 
Because manmade structures may fail, thus putting the environment at 
risk in the event of a discharge, there is an unacceptable risk in 
using such structures to justify relieving a facility from the burden 
of preparing a prevention plan. Secondary containment structures should 
be part of the prevention plan.
    Groundwater. EPA agrees with the commenter that groundwater 
underlying a facility that is directly connected hydrologically to 
navigable waters could trigger the requirement to produce an SPCC Plan 
based on geographic or locational aspects of the facility. See the 
discussion below for tanks regulated under 40 CFR part 280 or under a 
State program approved under 40 CFR part 281.
    EPA does not agree with the commenter that 40 CFR part 280 and a 
State program approved under 40 CFR part 281 (the rules governing most 
completely buried tanks) lack adequate emergency response provisions 
for regulated tanks and piping. 40 CFR part 280 and State programs 
approved under 40 CFR part 281 require corrective action, reporting, 
and recordkeeping requirements for any release from regulated tanks and 
piping. Also, 40 CFR parts 280 and 281 require various measures 
intended to prevent contamination that could result from releases from 
regulated tanks and piping. Although groundwater underlying a facility 
may eventually connect hydrologically to navigable waters, the 
requirements of 40 CFR part 280 and State programs approved under 40 
CFR part 281 are intended to address the prevention of releases from 
underground storage tanks that might have an impact on groundwater and 
to require rapid response and corrective action at such sites if they 
compromise groundwater quality.
    Editorial changes and clarifications. The proposed phrase in the 
first sentence which read, ``* * * could not reasonably be expected to 
discharge oil as described in Sec. 112.1(b)(1) of this part,'' becomes 
``* * * could not reasonably be expected to have a discharge as 
described in Sec. 112.1(b).'' The proposed phrase in the last sentence 
of the paragraph which read, ``* * * which may serve to restrain, 
hinder, contain, or otherwise prevent a discharge of oil from reaching 
navigable waters of the United States or adjoining shorelines. * * *'' 
becomes ``* * * which may serve to restrain, hinder, contain, or 
otherwise prevent a discharge as described in Sec. 112.1(b).''

Section 112.1(d)(1)(ii)--Exemptions Based on Function--DOT

    Background. In 1991, we republished, without substantive change, 
the current exemption for equipment or operations of vessels or 
transportation-related onshore and offshore facilities that are subject 
to the authority and control of the U.S. Department of Transportation 
(DOT). While we received no comments on the proposal, we believe that 
this provision merits a few words to clarify the understanding of the 
regulated community. The Executive Order (EO) implementing the Act 
assigns regulatory jurisdiction to three Federal agencies based on the 
function of facilities. Section 2(b)(1) of EO 12777 (56 FR 54757, 
October 22, 1991) delegates to the Administrator of EPA authority in 
section 311(j)(1)(C) relating to the establishment of procedures, 
methods, and equipment, and other requirements for equipment to prevent 
and to contain discharges of oil and hazardous substances from non-
transportation-related onshore facilities. Section 2(b)(2) of the EO 
delegates similar authority to contain discharges of oil and hazardous 
substances from vessels and transportation-related onshore facilities 
and deepwater ports to the Secretary of Transportation. Section 2(b)(3) 
of the EO delegates similar authority for offshore facilities, 
including associated pipelines, other than deepwater ports, to the 
Secretary of the Interior. A Memorandum of Understanding (MOU) among 
EPA, DOT, and the U.S. Department of the Interior (DOI), found at 
Appendix B to part 112, redelegated from DOI to EPA the responsibility 
for non-transportation-related offshore facilities located landward of 
the coastline. Similarly the MOU redelegated from DOI to DOT the 
responsibility for transportation-related offshore facilities, 
including pipelines, landward of the coastline.
    In 1993, we proposed a definition for the term ``complex,'' which 
is a facility possessing a combination of transportation-related and 
non-transportation-related components that is subject to the 
jurisdiction of more than one Federal agency under section

[[Page 47063]]

311(j) of the Clean Water Act. We published that definition on July 1, 
1994. 59 FR 34097. A commenter on the definition of ``breakout tank'' 
(see also discussion below on ``breakout tank'') asked for guidance as 
to which agency, DOT or EPA, regulates such tanks. Because of confusion 
in the regulated community over which Federal agencies have 
jurisdiction in complexes, we discuss the issue below.
    Complexes. ``Complex'' is defined at Sec. 112.2 as a ``facility 
possessing a combination of transportation-related and non-
transportation-related components that is subject to the jurisdiction 
of more than one Federal agency under section 311(j) of the Clean Water 
Act.'' The jurisdiction over a component of a complex is determined by 
the activity occurring at that component. An activity might at one time 
subject a facility to one agency's jurisdiction, and a different 
activity at the same facility using the same structure or equipment 
might subject the facility to the jurisdiction of another agency.
    Equipment, operations, and facilities are subject to DOT 
jurisdiction when they are engaged in activities subject to DOT 
jurisdiction. If those facilities are also engaged in activities 
subject to EPA jurisdiction, such activities would subject the 
equipment, operation, or facility to EPA jurisdiction. An example of an 
activity subject to EPA jurisdiction would be the loading or unloading 
of oil into a tank truck or railcar. Under an MOU between EPA and DOT 
(See Appendix A of part 112), transportation-related activities 
regulated by DOT and non-transportation-related activities regulated by 
EPA are defined. The MOU provides that highway vehicles and railroad 
cars which are used for the transport of oil in interstate or 
intrastate commerce and the equipment and appurtenances related 
thereto, and equipment used for the fueling of locomotive units, as 
well as the rights-of-way on which they operate, are considered 
transportation-related activities, subject to DOT jurisdiction.
    Another example of activities that might be considered a complex 
and therefore subject to both sets of rules is that of a breakout tank 
which is used for both transportation and non-transportation purposes. 
It is the activity to which the tank is put that determines 
jurisdiction. If you are an owner or operator of a complex, while you 
may not choose which agency will regulate your facility, you may choose 
not to engage in activities which would subject your facility to the 
jurisdiction of a particular agency if you do not wish to comply with 
that agency's rules. Otherwise, if you engage in activities subjecting 
your facility to the jurisdiction of two agencies, your facility would 
be subject to the more stringent of rules if there were to be a 
conflict or an inconsistency in those rules. For example, a facility 
with breakout tanks used solely to relieve surges in a pipeline, and 
not having another non-transportation-related activity or component, 
would not be required to have an SPCC Plan.
    Which activity would be subject to DOT jurisdiction and which 
activity which would be subject to EPA jurisdiction is defined by the 
MOU in Appendix A to part 112. The definitions in the MOU are keyed to 
the delegations of authority in EO 12777.
    Because regulatory jurisdiction is predicated upon the owner's or 
operator's activities at the facility, an owner or operator might have 
questions concerning that jurisdiction at his facility. To clarify 
regulatory jurisdiction, in February 2000, EPA and DOT signed a policy 
memorandum that described how the two agencies would work together to 
bring their respective regulations into alignment and, ultimately, to 
eliminate overlapping jurisdiction over tanks when possible.
    Recently, DOT informed EPA of a voluntary initiative to collect 
information from industry on breakout tanks, beginning in December 
2001. In anticipation of receiving the new tank information, DOT is 
considering updating the National Pipeline Mapping System (NPMS) data 
standards to reflect the guidelines for tank data submissions. 
Operators' data submissions will include the location of each tank farm 
with breakout tanks, information about each tank, and information about 
the accuracy of the data. The data will be depicted as a geospatial 
location in a digital file or a point located on a USGS 1:24,000 
topographic quad map.
    In addition to upgrading the NPMS, DOT is training its inspectors 
in tank inspection. In the President's Fiscal Year 2002 budget request, 
DOT expressed its intent to make tanks a priority in its compliance 
program, particularly where the tanks are in sensitive areas. DOT and 
EPA have agreed to provide cross-training of their respective 
personnel. As the two agencies proceed with tank oversight plans, the 
goal is to ensure that every tank is regulated and no tank is subject 
to overlapping regulations from two agencies.
    Editorial changes and clarifications. ``EPA Administrator'' becomes 
``Administrator of EPA.'' Another revision corrects an incorrect 
citation to the 1971 MOU between EPA and DOT.

Section 112.1(d)(1)(iii)--Exemptions Based on Function--DOT and DOI

    Background. We have added a new paragraph to the applicability 
section of the rule to note the jurisdictional changes resulting from 
an MOU between DOT, DOI, and EPA redelegating certain functions. The 
MOU was published on July 1, 1994 (at 59 FR 34102). The addition of 
this paragraph is not a substantive change in the rules, but merely an 
editorial revision to mark the jurisdiction of the respective agencies 
in this rule. It complements the other paragraphs in Sec. 112.1(d)(1) 
that describe facilities which are not subject to EPA jurisdiction. Due 
to the MOU, the referenced facilities, equipment, and operations of DOT 
and DOI in Sec. 112.1(d)(1)(iii), like the facilities, equipment, and 
operations described in Sec. 112.1(d)(1)(i) and (ii), are not subject 
to EPA jurisdiction under section 311(j)(1)(C) of the Act. They are not 
subject to EPA jurisdiction either because of their location, in the 
case of DOI facilities, or because of their activities, which are 
strictly transportation-related, in the case of DOT facilities.
    EO 12777 (56 FR 54757, October 22, 1991) delegates to DOI, DOT, and 
EPA various responsibilities identified in section 311(j) of the CWA. 
Sections 2(b)(3), 2(d)(3), and 2(e)(3) of EO 12777 assigned to DOI 
spill prevention and control, contingency planning, and equipment 
inspection activities associated with offshore facilities. Section 
311(a)(11) of the CWA defines the term ``offshore facility'' to include 
facilities of any kind located in, on, or under navigable waters of the 
United States. By using this definition, the traditional DOI role of 
regulating facilities on the Outer Continental Shelf was expanded by EO 
12777 to include inland lakes, rivers, streams, and any other inland 
waters.
    Under section 2(i) of EO 12777, DOI redelegated, and EPA and DOT 
accepted, the functions vested in DOI by sections 2(b)(3), 2(d)(3), and 
2(e)(3) of the EO. DOI redelegated to EPA the responsibility for non-
transportation-related offshore facilities located landward of the 
coastline. To DOT, DOI redelegated responsibility for transportation-
related facilities, including pipelines, located landward of the 
coastline. DOT retained jurisdiction for deepwater ports and the 
associated seaward pipelines. DOI retained jurisdiction over 
facilities, including pipelines, located seaward of

[[Page 47064]]

the coastline, except for deepwater ports and associated seaward 
pipelines. For purposes of the MOU, the term ``coastline'' means ``the 
line of ordinary low water along that portion of the coast which is in 
direct contact with the open sea and the line marking the seaward limit 
of inland waters.''

Section 112.1(d)(2)--Other Exemptions

Section 112.1(d)(2)(i)--Completely Buried Storage Tanks Currently 
Subject to all of the Technical Requirements of 40 CFR PART 280 or 
State Programs Approved under 40 CFR PART 281

    Background. Part 280 and approved State programs. In 1991, we 
proposed to exempt from the underground storage capacity of facilities 
in the SPCC rule the storage capacity of buried underground storage 
tanks (USTs) currently subject to all of the technical requirements of 
40 CFR part 280. We proposed this change as Sec. 112.1(d)(2)(i) in 
1991. We did not at the time include approved State programs in the 
proposal because in 1991 few if any States had such programs. In 40 CFR 
part 281 (published on September 23, 1988 at 53 FR 37212), EPA 
established regulations whereby a State could receive EPA approval for 
its State program to operate in lieu of the Federal program. In order 
to obtain EPA program approval under part 281, a State program must 
demonstrate that its requirements are no less stringent than the 
corresponding Federal regulations set forth in part 280, and that it 
provides adequate enforcement of these requirements. Thus, we have 
decided to exempt also the storage capacity of USTs subject to all of 
the technical requirements of State UST programs which EPA has 
approved. By January 2000, EPA had approved 27 State programs, plus 
programs in the District of Columbia and Puerto Rico. The rationale for 
exempting the storage capacity of these facilities from the SPCC regime 
is because 40 CFR part 280 and the approved State programs under 40 CFR 
part 281 provide comparable environmental protection for the purpose of 
preventing discharges as described in Sec. 112.1(b).
    Facilities with storage capacity not subject to part 280 or 
deferred from its provisions.
    Storage capacity not subject to part 280. Some UST facilities have 
storage capacity that is not subject to part 280, for example: any UST 
system holding hazardous wastes listed or identified under Subtitle C 
of the Solid Waste Disposal Act, or a mixture of such hazardous wastes 
and other regulated substances; wastewater treatment tank systems that 
are part of a wastewater treatment facility regulated under section 
307(b) or 402 of the Clean Water Act; equipment or machinery that 
contains regulated substances for operational purposes such as 
hydraulic lift tanks and electrical equipment tanks; and, UST systems 
whose capacity is 110 gallons or less. Also, part 280 does not provide 
for regulation of USTs storing animal fats and vegetable oils. All of 
these facilities remain potentially subject to the SPCC program.
    Tanks deferred from compliance with part 280 rules. Other 
facilities with storage capacity subject to part 280 are deferred from 
current compliance with most of the technical requirements of that 
part, including: wastewater treatment tank systems; any UST systems 
containing radioactive material that are regulated under the Atomic 
Energy Act of 1954 (42 U.S.C. 2011 et seq.); any UST system that is 
part of an emergency generator system at a nuclear power generation 
facility regulated by the Nuclear Regulatory Commission under 10 CFR 
part 50, Appendix A; airport hydrant fuel distribution systems; UST 
systems with field-constructed tanks; and, any UST system that stores 
fuel solely for use by an emergency power generator. All of these 
facilities remain potentially subject to the SPCC program.
    Tanks excluded from part 280 UST definition. Excluded from the 
definition of ``underground storage tank'' or ``UST'' in part 280 are 
a: (1) Farm or residential tank of 1,100 gallons or less capacity used 
for storing motor fuel for noncommercial purposes; (2) tank used for 
storing heating oil for consumptive use on the premises where stored; 
(3) septic tank; (4) pipeline facility (including gathering lines) 
regulated under: (a) the Natural Gas Pipeline Safety Act of 1968 (49 
U.S.C. App. 1671, et seq.), (b) the Hazardous Liquid Pipeline Safety 
Act of 1979 (49 U.S.C. App. 2001, et seq.), or (c) which is an 
intrastate pipeline facility regulated under State law comparable to 
the provisions of the Natural Gas Pipeline Safety Act of 1968 or the 
Hazardous Liquid Pipeline Safety Act of 1979; (5) surface impoundment, 
pit, pond, or lagoon; (6) storm-water or wastewater collection system; 
(7) flow-through process tank; (8) liquid trap or associated gathering 
lines directly related to oil or gas production and gathering 
operations; or, (9) storage tank situated in an underground area (such 
as a basement, cellar, mineworking, drift, shaft, or tunnel) if the 
storage tank is situated upon or above the surface of the floor. An UST 
system includes the tank itself, connected underground piping, 
underground ancillary equipment, and containment system. Therefore, any 
of these tank systems may be potentially subject to the SPCC program.
    Definitions. EPA proposed to define an UST as any tank which is 
completely covered with earth. Part 280 includes a broader definition 
of underground storage tanks, and includes partially buried and 
bunkered tanks. Partially buried tanks and bunkered tanks are excluded 
from the definition of ``completely buried tank'' in part 112, and are 
considered aboveground storage tanks (ASTs) for purposes of the rule, 
as are tanks in vaults. These tanks are not included in today's 
exemption because compared to completely buried tanks, partially buried 
and bunkered tanks are more likely to cause a discharge as described in 
Sec. 112.1(b).
    Although most USTs will be exempt from the SPCC rule (see the above 
discussion on Sec. 112.1(d)(4)), a facility might have non-exempt USTs 
for which it must prepare a facility SPCC Plan. If part of your 
facility is subject to the rule, you must mark the location and 
contents of all containers, including exempt and non-exempt USTs, on 
the facility diagram. 40 CFR 112.1(d)(4). The rationale for this 
requirement is to help response personnel to easily identify dangers 
from either fire or explosion, or physical impediments during spill 
response activities. In addition, facility diagrams may be referred to 
in the event of design modifications. 56 FR 54626.
    Capacity calculations. To calculate the 42,000-gallon threshold 
which subjects a facility operating a completely buried tank to the 
SPCC rule, you may exclude the storage capacity of any completely 
buried tank currently subject to all of the technical requirements of 
40 CFR part 280 or of an approved State program under 40 CFR part 281. 
Thus we expect you will count few completely buried tanks containing 
petroleum products in that calculation. You must count the capacity of 
completely buried tanks containing products which are not regulated 
under part 280 or an approved State program under part 281, or which 
are not currently subject to all of its technical requirements.
    Permanently closed tanks. In 1991, EPA proposed that the 
underground storage capacity of a facility does not include the 
capacity of underground tanks that are ``permanently closed'' as 
defined in Sec. 112.2. Under today's rule, you may exclude the capacity 
of tanks that are permanently closed, as defined in Sec. 112.2, in 
completely buried tank capacity calculations.

[[Page 47065]]

    Comments. Completely buried storage tanks. Favorable comments. 
Commenters overwhelmingly favored eliminating dual regulation of ASTs 
and USTs. Most agreed that the UST program provides protection 
comparable to the SPCC program. Several argued that all USTs as defined 
in part 280, which includes partially buried and bunkered tanks, should 
be exempted. Others argued that tanks deferred under the UST program 
should be exempted from the SPCC program. Another commenter suggested 
that piping connecting exempted USTs to regulated ASTs should be 
exempted from the SPCC rules. The commenter added that if such piping 
is subject to leak detection requirements for USTs under 40 CFR part 
280, then it should remain exclusively under UST rules and be exempted 
from SPCC rules.
    Opposing comments. Several commenters, however, opposed the 
proposed exemption of USTs from the SPCC program. Those commenters 
argued that the SPCC rules are not duplicative. They asserted that UST 
rules lack provisions concerning contingency planning; emergency 
response; periodic training of personnel to deal with emergencies; 
maintenance of records regarding inspections and tests; maintenance of 
records regarding discharges to navigable waters or adjoining 
shorelines; diking of fuel transfer areas; fuel transfer area 
operational procedures; illumination of fuel transfer areas; stormwater 
drainage system design; posting of vehicle weight restrictions in areas 
where there is underground piping and/or design of underground piping 
to withstand vehicular loadings; a requirement for an application of 
``good engineering practice,'' in other words, no requirements that the 
design and construction of a UST system be overseen by a Professional 
Engineer; a requirement that management sign the Plan; and, ``other 
topics enumerated in 40 CFR 112.7.'' One commenter noted that since 
groundwater becomes surface water eventually, whether within minutes or 
months, the absence of emergency provisions in the UST program might 
cause environmental problems. Another commenter argued that the new 
regulatory scheme would be confusing because a facility might have some 
containers subject to SPCC and some that are not, as well as containers 
that may be subject to State regulation.
    Response to comments. Completely buried storage tanks. As we noted 
above, in the discussion of Sec. 112.1(d)(1)(i), the UST program 
provides comparable environmental protection to the SPCC program. While 
not all aspects of the programs are identical, the UST program ensures 
protection against discharges as described in Sec. 112.1(b), and 
protection of the environment. Therefore, dual regulation is 
unnecessary. In response to commenters asserting that UST rules lack 
provisions concerning contingency planning; emergency response; certain 
recordkeeping requirements; and other alleged deficiencies, we 
disagree. The UST rules have numerous safeguards addressing the 
commenter's issues.
    Partially buried tanks and bunkered tanks. We disagree that 
partially buried tanks and bunkered tanks should be considered 
completely buried tanks, and therefore excluded from SPCC provisions. 
Such tanks may suffer damage caused by differential corrosion of buried 
and non-buried surfaces greater than completely buried tanks, which 
could cause a discharge as described in Sec. 112.1(b). Such tanks are 
also not subject to secondary containment requirements under part 280 
or a State program approved under 40 CFR part 281. There may also be 
accidents during loading or unloading operations, or overfills 
resulting in a discharge to navigable waters and adjoining shorelines. 
Furthermore, a failure of such a tank (caused by accident or vandalism) 
would be more likely to cause a discharge as described in 
Sec. 112.1(b).
    Contingency planning. While it is true that UST rules do not 
require contingency planning, spills and overfills of USTs resulting in 
a discharge to the environment are much less likely as a result of 
those rules. An owner or operator of an underground storage tank 
subject to 40 CFR part 280 or a State program approved under 40 CFR 
part 281 was required to install spill and overfill prevention 
equipment no later than December 22, 1998. 40 CFR 280.20 and 280.21. 
The use of this equipment will greatly reduce the likelihood of both 
small and large releases or discharges of petroleum to the environment 
through surface spills or overfilling underground storage tanks. In 
addition, the UST rules place a general responsibility on the owner or 
operator to ensure that discharges due to spilling and overfilling do 
not occur. See 40 CFR 280.30.
    Emergency response and release reporting. The UST rules also have 
several requirements related to emergency response and release or 
discharge reporting. The UST rules generally require that releases of 
regulated substances be reported to the implementing agency within 24 
hours. As part of the initial response requirements (found at 40 CFR 
280.61), an owner or operator must take immediate action to prevent 
further release of the regulated substance and must identify and 
mitigate fire, explosion, and vapor hazards.
    Reporting and recordkeeping. In addition to the reporting 
requirements mentioned above, there are numerous reporting and 
recordkeeping requirements in the rules governing underground storage 
tanks. Among these are: corrective action plans; documentation of 
corrosion protection equipment; documentation of UST system repairs; 
and, information concerning recent compliance with release detection 
requirements. Thus, the UST rules have significant reporting and 
recordkeeping requirements, including specific requirements related to 
spills and overfills.
    Transportation rules. In addition to the EPA UST rules, the U.S. 
Department of Transportation has hazardous material regulations related 
to driver training, emergency preparation, and incident reporting and 
emergency response. Training regulations, for example, can be found at 
49 CFR part 172, and loading and unloading regulations can be found at 
49 CFR 177.834 and 49 CFR 177.837. These regulations apply, for 
example, to truck drivers delivering gasoline or diesel fuel to gas 
stations with underground storage tanks.
    Section 112.1(f). Finally, as a safeguard, today's rule (see 
Sec. 112.1(f) in today's preamble) provides the Regional Administrator 
with the authority to require any facility subject to EPA jurisdiction 
under section 311 of the CWA, regardless of threshold or other 
regulatory exemption, to prepare and implement an SPCC Plan when 
necessary to further the purposes of the Act.
    Regulatory jurisdiction. To eliminate any possible confusion over 
regulatory jurisdiction, we explain in this preamble (see the above 
background discussion) which containers in a facility are subject to 40 
CFR part 280 or a State program approved under 40 CFR part 281 and 
which are subject to part 112.
    Piping, ancillary equipment, and containment systems. EPA has 
modified the scope of the proposed exemption for completely buried 
tanks (which are excluded from the scope of the SPCC rule if they are 
subject to all of the technical requirements of 40 CFR part 280 or a 
State program approved under 40 CFR part 281) by clarifying that the 
exemption includes the connected underground piping, underground 
ancillary equipment, and containment

[[Page 47066]]

systems, in addition to the tank itself. This modification is 
consistent with the definition of underground storage tank system found 
at 40 CFR 280.12. In addition, this clarification is responsive to the 
comment which asked that the piping be included in the exemption.
    Deferred tanks. We disagree that we should not regulate tanks which 
are deferred from compliance with any of the technical requirements of 
40 CFR part 280 or a State program approved under 40 CFR part 281. 
These are containers from which a discharge as described in 
Sec. 112.1(b) may occur, and thus are properly subject to the SPCC 
rule. Furthermore, if they were not regulated by SPCC rules, they may, 
in some instances, not be regulated at all.
    Effect on Facility Response Plan facilities. The exemption for 
completely buried tanks subject to all the technical requirements of 40 
CFR part 280 or a State program approved under 40 CFR part 281 applies 
to the calculation of storage capacity both for SPCC purposes and for 
Facility Response Plan (FRP) purposes because the exemption applies to 
all of part 112. Therefore, a few FRP facilities with large capacity 
completely buried tanks subject to 40 CFR part 280 or a State program 
approved under 40 CFR part 281 might no longer be required to have 
FRPs. Calculations for planning levels for worst case discharges will 
also be affected. However, the Regional Administrator retains authority 
to require the owner or operator of any non-transportation-related 
onshore facility to prepare and submit a FRP after considering the 
factors listed in Sec. 112.20(f)(2). See Sec. 112.20(b)(1).
    Editorial changes and clarifications. ``Underground storage tanks'' 
becomes ``completely buried storage tanks.'' The phrase ``does not 
include'' becomes ``excludes.'' We have amended the rule to clarify 
that facilities must be subject to ``all of'' the technical 
requirements of 40 CFR part 280 or of a State program approved under 40 
CFR part 281 to qualify for the SPCC exemption. If a facility is 
subject to some, but not all of the UST requirements, it may be subject 
to the SPCC rule. Facilities in this category include those which are 
excluded from UST requirements, or deferred from compliance with some 
or all of those requirements.

Section 112.1(d)(2)(ii)--AST Threshold, Minimum Container Size, 
Permanently Closed Tanks

    Background. Regulatory thresholds. In the 1997 preamble, we asked 
for comment as to whether any change in the level of storage capacity 
which subjects a facility to this rule is justified. 62 FR 63813. We 
noted that we were considering eliminating the provision in the current 
rule that requires a facility having an aboveground container in excess 
of 660 gallons to prepare an SPCC Plan, as long as the total 
aboveground capacity of the facility remained at 1,320 gallons or less. 
The effect of such a change would be to raise the threshold for 
regulation to an aboveground storage capacity greater than 1,320 
gallons.
    In 1991, EPA also proposed that the aboveground storage capacity of 
a facility does not include the capacity of aboveground storage 
containers that are ``permanently closed'' as defined in Sec. 112.2.
    Comments. Minimum size container. Numerous commenters suggested a 
de minimis size for containers to be used for AST capacity 
calculations. Most of the suggestions came in the context of the 
discussion of the proposed definition of ``bulk storage tank.'' 
Suggestions for a minimum size ranged from over 55 gallons to 25,000 
gallons. The bulk of the commenters favored either a greater than 55-
gallon number, or a greater than 660-gallon figure.
    Regulatory thresholds. Higher threshold. Commenters offered 
numerous threshold levels in both 1991 and 1997. Suggestions for the 
regulatory threshold in 1991 ranged from greater than 1,320 gallons to 
120,000 gallons. Many commenters, particularly utilities, favored 
thresholds in the 10,000-42,000-gallon range. In 1997, when EPA 
suggested it might consider a greater than 1,320-gallon threshold, many 
commenters favored that suggestion. Others urged thresholds ranging up 
to 15,000 gallons.
    Lower threshold. A few commenters suggested lowering the threshold. 
Commenters suggested threshold levels of 110 and 250 gallons. The 
general rationale for these suggestions was that oil spills causing 
even a sheen can be devastating. Therefore, these commenters reasoned 
that sheens from home heating oil tanks of 110 gallons, i.e., two 55-
gallon drums, are every bit as important as sheens from crude oil 
tanks. An advocate for a lower threshold noted that manufacturers now 
sell, market, and produce fuel containers of 650 gallons designed to 
avoid compliance with the rule, whether the site is adjacent to 
navigable waterways or not. The commenter added that most manufacturers 
market or sell a ``listed'' tank of 250 gallons, and that under current 
rules, five of these tanks would not subject a facility to the SPCC 
rule, yet the risk would be nearly identical to one larger tank of 
1,250 gallons depending upon the design of the tank.
    Response to comments. Minimum container size. In response to 
comments, we are introducing a minimum container size. The 55 gallon 
container is the most widely used commercial bulk container, and these 
containers are easily counted. Containers below 55 gallons in capacity 
are typically end-use consumer containers. Fifty-five gallon containers 
are also the lowest size bulk container that can be handled by a human. 
Containers above that size typically require equipment for movement and 
handling. We considered a minimum container size of one barrel. 
However, a barrel or 42 gallons is a common volumetric measurement size 
for oil, but is not a common container size. Therefore, it would not be 
appropriate to institute a 42 gallon minimum container size.
    You need only count containers of 55 gallons or greater in the 
calculation of the regulatory threshold. You need not count containers, 
like pints, quarts, and small pails, which have a storage capacity of 
less than 55 gallons. Some SPCC facilities might therefore drop out of 
the regulated universe of facilities. You should note, however, that 
EPA retains authority to require any facility subject to its 
jurisdiction under section 311(j) of the CWA to prepare and implement 
an SPCC Plan, or applicable part, to carry out the purposes of the Act.
    While some commenters had suggested a higher threshold level, we 
believe that inclusion of containers of 55 gallons or greater within 
the calculation for the regulatory threshold is necessary to ensure 
environmental protection. If we finalized a higher minimum size, the 
result in some cases would be large amounts of aggregate capacity that 
would not be counted for SPCC purposes, and would therefore be 
unregulated, posing a threat to the environment. We believe that it is 
not necessary to apply SPCC or FRP rules requiring measures like 
secondary containment, inspections, or integrity testing, to containers 
smaller than 55 gallons storing oil because a discharge from these 
containers generally poses a smaller risk to the environment. 
Furthermore, compliance with the rules for these containers could be 
extremely burdensome for an owner or operator and could upset 
manufacturing operations, while providing little or no significant 
increase in protection of human health or the environment. Many of 
these smaller containers are constantly being emptied, replaced, and 
relocated so that serious corrosion will likely soon be detected and 
undetected leaks become highly unlikely. While we realize that small 
discharges may harm

[[Page 47067]]

the environment, depending on where and when the discharge occurs, we 
believe that this measure will allow facilities to concentrate on the 
prevention and containment of discharges of oil from those sources most 
likely to present a more significant risk to human health and the 
environment.
    Effect on Facility Response Plan facilities. The exemption for 
containers of less than 55 gallons applies to the calculations of 
storage capacity both for SPCC purposes and for FRP purposes because 
the exemption applies to all of part 112. Therefore, a few FRP 
facilities might no longer be required to have FRPs. The calculations 
for planning levels for worst case discharges would also be affected.
    Regulatory thresholds. We have decided to raise the current 
regulatory threshold, as discussed in the 1997 preamble, to an 
aggregate threshold of over 1,320 gallons. We believe that raising the 
regulatory threshold is justified because our Survey of Oil Storage 
Facilities (published in July 1996, and available on our Web site at 
www.epa.gov/oilspill) points to the conclusion that several facility 
characteristics can affect the chances of a discharge. First, the 
Survey showed that as the total storage capacity increases, so does the 
propensity to discharge, the severity of the discharge, and the costs 
of cleanup. Likewise, the Survey also pointed out that as the number of 
tanks increases, so does the propensity to discharge, the severity of 
the discharge, and the costs of cleanup. Finally, the Survey showed 
that as annual throughput increases, so does the propensity to 
discharge, the severity of the discharge, and, to a lesser extent, the 
costs of the cleanup.
    The threshold change will have several benefits. The threshold 
increase will result in a substantial reduction in information 
collection associated with the rule overall. Some smaller facilities 
will no longer have to bear the costs of an SPCC Plan. EPA will be 
better able to focus its regulatory oversight on facilities that pose a 
greater likelihood of a discharge as described in Sec. 112.1(b), and a 
greater potential for injury to the environment if a discharge as 
described in Sec. 112.1(b) results.
    We raise the regulatory threshold realizing that discharges as 
described in Sec. 112.1(b) from small facilities may be harmful, 
depending on the surrounding environment. Among the factors remaining 
to mitigate any potential disasters are that small facilities no longer 
required to have SPCC Plans are still liable for cleanup costs and 
damages from discharges as described in Sec. 112.1(b). We encourage 
those facilities exempted from today's rule to maintain SPCC Plans. 
Likewise, we encourage facilities becoming operable in the future with 
storage or use capacity below the regulatory threshold to develop 
Plans. We believe that SPCC Plans have utility and benefit for both the 
facility and the environment. But, we will no longer by regulation 
require Plans from exempted facilities.
    While we believe that the Federal oil program is best focused on 
larger risks, State, local, or tribal governments may still decide that 
smaller facilities warrant regulation under their own authorities. In 
accord with this philosophy, we note that this Federal exemption may 
not relieve all exempted facilities from Plan requirements because some 
States, local, or tribal governments may still require such facilities 
to have Plans. While we are aware that some States, local, or tribal 
governments have laws or policies allowing them to set requirements no 
more stringent than Federal requirements, we encourage States, local, 
or tribal governments to maintain or lower regulatory thresholds to 
include facilities no longer covered by Federal rules where their own 
laws or policies allow. We believe that CWA section 311(o) authorizes 
States to establish their own oil spill prevention programs which can 
be more stringent than EPA's program.
    Regulatory safeguard. When a particular facility that is below 
today's threshold becomes a hazard to the environment because of its 
practices, or when needed for other reasons to carry out the Clean 
Water Act, the Regional Administrator may, under a new rule provision, 
require that facility to prepare and implement an SPCC Plan. See 
Sec. 112.1(f). This provision acts as a safeguard to an environmental 
threat from any exempted facility.
    Editorial changes and clarifications. The reference to 
``underground storage tanks'' was deleted because it is unnecessary. A 
reference to the exemption of certain ``completely buried'' storage 
tanks from the rules is contained in Sec. 112.1(d)(4).

Section 112.1(d)(3)--Minerals Management Service Facilities

    Background. In 1991, EPA proposed to exempt from the SPCC rule 
facilities subject to Minerals Management Service (MMS) Operating 
Orders, notices, and regulations. The rationale for the 1991 proposal 
was to avoid redundancy in regulation, based on EPA's analysis that MMS 
Operating Orders require adequate spill prevention, control, and 
countermeasures that are directed more specifically to the facilities 
subject to MMS requirements. Until October 22, 1991, the date of the 
1991 proposed rule, responsibility for the establishment of procedures, 
methods, and equipment and other requirements for equipment to prevent 
and to contain discharges of oil from offshore facilities, including 
associated pipelines, other than deepwater ports subject to the 
Deepwater Ports Act, was delegated to EPA. Under EO 12777 (56 FR 54747, 
October 22, 1991), responsibility for the establishment of procedures, 
methods, and equipment and other requirements for equipment to prevent 
and to contain discharges of oil from offshore facilities, including 
associated pipelines, other than deepwater ports subject to the 
Deepwater Ports Act, was redelegated to the U.S. Department of the 
Interior (DOI). These facilities are generally offshore oil production 
or exploration facilities.
    In 1994, in another Memorandum of Understanding (MOU) found in 
Appendix B of part 112, EPA, DOI, and DOT redelegated the 
responsibility to regulate non-transportation-related offshore 
facilities located in and along the Great Lakes, rivers, coastal 
wetlands, and the Gulf Coast barrier islands from DOI to EPA.
    Because of the redelegation of responsibility, some DOI facilities 
again became subject to the jurisdiction of EPA under section 
311(j)(1)(C) of the Act. We added a reference to the MOU in the rule.
    Comments. Most commenters favored the proposed exemption because 
they believed that MMS orders, notices, and regulations require oil 
spill prevention and contingency planning equivalent to the 
environmental protection envisioned by EPA's rules. Two commenters, 
both States, opposed the proposal. One was concerned with MMS' 
``historic treatment of identified violations.'' The other suggested 
that the more stringent of EPA or MMS regulations apply.
    Response to comments. We have retained our original proposal, 
except for the editorial revision, because we believe that MMS will 
provide equivalent environmental protection for the facilities under 
its jurisdiction. MMS regulations require adequate spill prevention, 
control, and countermeasures that are directed more specifically to the 
facilities subject to MMS requirements.
    Editorial changes and clarifications. The term ``Operating Orders'' 
becomes ``regulations.''

[[Page 47068]]

Section 112.1(d)(4)--Completely Buried Storage Tanks

    Background. This paragraph is a companion paragraph to 
Sec. 112.1(d)(2)(i) for purposes of SPCC exemption. As in 
Sec. 112.1(d)(2)(i), we have also exempted connected underground 
piping, underground ancillary equipment, and containment systems 
subject to all of the technical requirements of part 280 or a State 
program approved under 40 CFR part 281. We also added a clause noting 
that these exempted tanks must be marked on the facility diagram as 
provided in Sec. 112.7(a)(3), if the facility is otherwise subject to 
this part. See the discussion above concerning Sec. 112.1(d)(2)(i).
    Editorial changes and clarifications. ``Underground storage tanks'' 
becomes ``completely buried storage tanks.'' We also reference 40 CFR 
part 281.

Section 112.1(d)(5)--Minimum Size Exemption

    Background. This is a new section we added in response to comments 
pertaining to the regulatory threshold/minimum container size issue 
discussed above. This section clarifies that any aboveground or 
completely buried container with capacity of less than 55 gallons is 
not subject to the rule. It is a companion rule to Sec. 112.1(d)(2)(ii) 
for purposes of SPCC exemption. See the discussion above concerning 
Sec. 112.1(d)(2)(ii).

Section 112.1(d)(6)--Wastewater Treatment Facility Exemption

    Background. In 1991, EPA proposed various changes to Sec. 112.1(d) 
concerning exemptions to part 112, and received comments on its 
proposals. Among those comments was one suggesting an exemption for 
certain treatment systems.
    Comments. One commenter suggested that the ``Sec. 112.1 exceptions 
should be expanded to include facility storage and treatment tanks 
associated with `non-contact cooling water systems' and/or `storm water 
retention and treatment systems.' Although these tanks are designed to 
remove spilled oil from manufacturing operations and parking lot 
runoff, the concentration of oil in the water at any given time would 
be insignificant. These tanks are typically very large, i.e., in excess 
of 100,000 gallons, and are typically not contained by diked walls or 
impervious surfaces. GM believes the cost to contain these structures 
could be better spent on other SPCC regulatory requirements.''
    Response to comments. We agree with the commenter that certain 
wastewater treatment facilities or parts thereof should be exempted 
from the rule, if used exclusively for wastewater treatment and not 
used to meet any other requirement of part 112. We have therefore 
amended the rule to reflect that agreement. No longer subject to the 
rule would be wastewater treatment facilities or parts thereof such as 
treatment systems at POTWs and industrial facilities treating oily 
wastewater.
    Many of these wastewater treatment facilities or parts thereof are 
subject to NPDES or state-equivalent permitting requirements that 
involve operating and maintaining the facility to prevent discharges. 
40 CFR 122.41(e). The NPDES or state-equivalent process ensures review 
and approval of the facility's: plans and specifications; operation/
maintenance manuals and procedures; and, Stormwater Pollution 
Prevention Plans, which may include Best Management Practice Plans 
(BMP).
    Many affected facilities are subject to a BMP prepared under an 
NPDES permit. Some of those plans provide protections equivalent to 
SPCC Plans. BMPs are additional conditions which may supplement 
effluent limitations in NPDES permits. Under section 402(a)(1) of the 
CWA, BMPs may be imposed when the Administrator determines that such 
conditions are necessary to carry out the provisions of the Act. See 40 
CFR 122.44(k). CWA section 304(e) authorizes EPA to promulgate BMPs as 
effluent limitations guidelines. NPDES rules provide for BMPs when: 
authorized under section 304(e) of the CWA for the control of toxic 
pollutants and hazardous substances; numeric limitations are 
infeasible; or, the practices are reasonably necessary to achieve 
effluent limitations and standards to carry out the purposes of the 
CWA. In addition, each NPDES or state equivalent permit for a 
wastewater treatment system must contain operation and maintenance 
requirements to reduce the risk of discharges. 40 CFR 122.41(e).
    Additionally, some wastewater is pretreated prior to discharge to a 
permitted wastewater treatment facility. The CWA authorizes EPA to 
establish pretreatment standards for pollutants that pass through or 
interfere with the operation of POTWs. The General Pretreatment 
Regulations (GPR), which set for the framework for the implementation 
of categorical pretreatment standards, are found at 40 CFR part 403. 
The GPR prohibit a user from introducing a pollutant into a POTW which 
causes pass through or interference. 40 CFR 403.5(a)(1). More 
specifically, the GPR also prohibit the introduction into of POTW of 
``petroleum, oil, nonbiodegradable cutting oil, or products of mineral 
oil origin in amounts that will cause interference or pass through. 40 
CFR 403.5(b)(6). EPA believes that the GPR and the more specific 
categorical pretreatment standards, some of which allow indirect 
dischargers to adopt a BMP as an alternative way to meet pretreatment 
standards, will work to prevent the discharge of oil from wastewater 
treatment systems into navigable waters or adjoining shorelines by way 
of a POTW.
    However, if a wastewater facility or part thereof is used for the 
purpose of storing oil, then there is no exemption, and its capacity 
must be counted as part of the storage capacity of the facility. Any 
oil storage capacity associated with or incidental to these wastewater 
treatment facilities or parts thereof continues to be subject to part 
112. At permitted wastewater treatment facilities, storage capacity 
includes bulk storage containers, hydraulic equipment associated with 
the treatment process, containers used to store oil which feed an 
emergency generator associated with wastewater treatment, and slop 
tanks or other containers used to store oil resulting from treatment. 
Some flow through treatment such as oil/water separators have a storage 
capacity within the treatment unit itself. This storage capacity is 
subject to the rule. An example of a wastewater treatment unit that 
functions as storage is a treatment unit that accumulates oil and 
performs no further treatment, such as a bulk storage container used to 
separate oil and water mixtures, in which oil is stored in the 
container after removal of the water in the separation/treatment 
process.
    We do not consider wastewater treatment facilities or parts thereof 
at an oil production, oil recovery, or oil recycling facility to be 
wastewater treatment for purposes of this paragraph. These facilities 
generally lack NPDES or state-equivalent permits and thus lack the 
protections that such permits provide. Production facilities are 
normally unmanned and therefore lack constant human oversight and 
inspection. Produced water generated by the production process normally 
contains saline water as a contaminant in the oil, which might 
aggravate environmental conditions in addition to the toxicity of the 
oil in the case of a discharge.
    Additionally, the goal of an oil production, oil recovery, or oil 
recycling facility is to maximize the production or recovery of oil, 
while eliminating impurities in the oil, including water, whereas the 
goal of a wastewater

[[Page 47069]]

treatment facility is to purify water. Neither an oil production 
facility, nor an oil recovery or oil recycling facility treats water, 
instead they treat oil. For purposes of this exemption, produced water 
is not considered wastewater and treatment of produced water is not 
considered wastewater treatment. Therefore, a facility which stores, 
treats, or otherwise uses produced water remains subject to the rule. 
At oil drilling, oil production, oil recycling, or oil recovery 
facilities, treatment units subject to the rule include open oil pits 
or ponds associated with oil production operations, oil/water 
separators (gun barrels), and heater/treater units. Open oil pits or 
ponds function as another form of bulk storage container and are not 
used for wastewater treatment. Open oil pits or ponds also pose 
numerous environmental risks to birds and other wildlife.
    Examples of wastewater treatment facilities or parts thereof used 
to meet a part 112 requirement include an oil/water separator used to 
meet any SPCC requirement. Oil/water separators used to meet SPCC 
requirements include oil/water separators used as general facility 
secondary containment (i.e., Sec. 112.7(c), secondary containment 
requirements for loading and unloading (i.e., Sec. 112.7(h)), and for 
facility drainage (i.e., Sec. 112.8(b) or Sec. 112.9(b)).
    Whether a wastewater treatment facility or part thereof is used 
exclusively for wastewater treatment (i.e., not storage or other use of 
oil) or used to satisfy a requirement of part 112 will often be a 
facility specific determination based on the activity associated with 
the facility or part thereof. Only the portion of the facility (except 
at an oil production, oil recovery, or oil recycling facility) used 
exclusively for wastewater treatment and not used to meet any part 112 
requirement is exempt from part 112. Storage or use of oil at such a 
facility will continue to be subject to part 112.
    Although we exempt wastewater treatment facilities or parts thereof 
from the rule under certain circumstances, a mixture of wastewater and 
oil still is ``oil'' under the statutory and regulatory definition of 
the term (33 U.S.C. 1321(a)(1) and 40 CFR 110.2 and 112.2). Thus, while 
we are excluding from the scope of the rule certain wastewater 
treatment facilities or parts thereof, a discharge of wastewater 
containing oil to navigable waters or adjoining shorelines in a 
``harmful quantity'' (40 CFR part 110) is prohibited. Thus, to avoid 
such discharges, we would expect owners or operators to comply with the 
applicable permitting requirements, including best management practices 
and operation and maintenance provisions.

Proposed Sec. 112.1(e)--Facility Notification

    Background. In 1991, EPA proposed to require that any facility 
subject to its jurisdiction under the Clean Water Act which also meets 
the regulatory storage capacity threshold notify the Agency on a one-
time basis of its existence. CWA section 311(m) provides EPA with the 
authority to require the owner or operator of a facility subject to 
section 311 to make reports and provide information to carry out the 
objectives of section 311. Any owner or operator who failed to notify 
or knowingly submitted false information in a notification would be 
subject to a civil penalty. This type of notice is separate from the 
notice required at 40 CFR 110.3 of discharges which may be harmful to 
the public health or welfare or the environment. We did not propose any 
changes to the notice requirements in Sec. 110.3.
    We proposed that facility notification include, among other items, 
information concerning the number, size, storage capacity, and 
locations of ASTs. The proposal would have exempted information 
regarding the number and size of completely buried tanks, as defined in 
Sec. 112.2, from the notification requirement. The rationale for 
notification was that submission of this information would be needed to 
help us identify our universe of facilities and to help us administer 
the Oil Pollution Prevention Program by creating a data base of 
facility-specific information. We also asked for comments regarding the 
form on which notification would be submitted, and on various possible 
items of information that could be included besides the ones proposed. 
Lastly, we asked for comments on alternate forms of facility 
notification. 56 FR 54614-15.
    Comments. Favorable comments. A number of commenters favored the 
proposal, including some industry commenters. These commenters stated 
that there was generally no current procedure whereby EPA can identify 
the universe of sites subject to the SPCC rule, and that an inventory 
of these facilities is necessary.
    Opposing comments. Most industry commenters opposed the proposal 
either in part or in its entirety.
    Sources of information. Commenters who opposed the proposal in its 
entirety asserted that it was unnecessary, largely because they 
believed the information sought might be better obtained from other 
sources, such as State sources or SARA Title III reports. Some States 
wanted copies of the notifications EPA would receive, and at least one 
suggested requiring updates. One commenter suggested that we gather the 
information through representative sampling at on-site surveys. Another 
commenter suggested that we use spill reports already submitted because 
it makes more sense to regulate those facilities whose practices have 
led to a spill.
    Applicability. Other commenters criticized the fact that the 
proposal would have been applicable to facilities which were not 
subject to the SPCC rule. Their solution was to limit applicability to 
facilities currently regulated under part 112.
    Terrorism. One commenter suggested that the aggregation of such 
strategic information in an easily accessed data base like a facility 
notification data base could provide an intelligence windfall to 
terrorists and other enemies of our nation.
    Small facilities. Commenters for small facilities argued that 
facility notification would cause a deluge of notifications to be sent 
to EPA with little or no environmental benefit. Some of these 
commenters suggested exempting small facilities at various levels of 
storage capacity, for example, 42,000 gallons or 100,000 gallons.
    Notification time line. In particular, commenters questioned 
various aspects of the proposal. Many questioned the necessity of 
providing the information within the proposed two months time frame. 
Some commenters suggested other time periods ranging from ``more than 
two months'' to 18 months. However, the bulk of the commenters favored 
a six month period for facility notification if notification were to be 
required. Others favored a ``phase-in'' of the requirements.
    Who must notify. Some commenters asked who must notify, the owner 
or operator. They noted that these might be different persons. One 
commenter suggested that the operator of the facility, the owner of any 
improvements at the facility, and the owner of the land at the facility 
should be required to submit facility notification. The commenter 
argued that the United States government is the landowner most 
prejudiced by the absence of a requirement of landowner involvement in 
the preparation of an SPCC plan because an owner or operator can 
prepare a minimal SPCC Plan and not even inform the landowner of it.
    Location issues. Others questioned the proposed requirement for the 
name, address, and zip code of the facility, arguing that provision of 
such information was not always possible,

[[Page 47070]]

especially in remote rural areas. Some noted that drilling rigs move 
from location to location as often as every few months. Commenters 
suggested alternatives such as use of longitude and latitude, or the 
Universal Transverse Mercator system, or a mailing address.
    Storage capacity. A number of commenters had concerns about the 
requirement for the total number and size of ASTs, and the total AST 
capacity of the facility. Commenters noted that there was no space on 
the form for containers less than 250 gallons. Other commenters asked 
if additions to storage capacity would trigger a new notification. Some 
commenters believed that storage capacity could be measured by SARA 
Title III information.
    Distance to navigable waters. The proposed requirement to detail 
the distance to the nearest navigable water elicited many comments. 
Some commenters noted that there was no definition of navigable waters 
on the form, making it difficult for some responders to answer the 
question. Others asserted that making the determination on distance to 
navigable waters was a difficult one due to litigation concerning the 
definition of the term. Yet other commenters thought that we should 
specify a minimum distance to navigable waters, on the theory that only 
facilities within a certain distance would have a reasonable 
possibility of discharge to such waters.
    Classification of facilities. One commenter noted that exploration 
and production facilities rarely have Dun & Bradstreet numbers, and 
that the information received from Dun & Bradstreet might be irrelevant 
for our purposes. Regarding the reporting of Standard Industrial 
Classification codes (SIC) (now replaced by North American Industry 
Classification System (NAICS) codes), commenters asserted that EPA used 
inaccurate codes, that no codes were listed for edible oil facilities, 
and that the codes listed were misleading in that they did not cover 
all possible industries regulated.
    Use of oil. Permanently closed containers. Facilities using 
primarily oil-filled equipment, not bulk storage containers, asked 
whether they too were covered by the notification proposal. Other 
commenters asked for clarification as to whether permanently closed 
tanks were covered by the proposal.
    Possible additional items. There were numerous comments on various 
additional items for which EPA had requested comment, but which were 
not included in the proposal. Possible additional items included: 
latitude and longitude of the facility; location of environmentally 
sensitive areas and potable water supplies; presence of secondary 
containment; spill history; leak detection equipment and alarms; age of 
the tanks; potential for adverse weather; and, for field verification 
purposes, a requirement to have storage facilities placarded or 
similarly identified. Most commenters opposed the inclusion of 
additional items. Several supported these additions as well as the 
addition of other information, particularly information concerning tank 
materials, methods of construction (for example, field-or shop-erected) 
and substance stored.
    Response to comments. Withdrawal of proposal. We have decided to 
withdraw the proposed facility notification requirement because we are 
still considering issues associated with establishing a paper versus 
electronic notification system, including issues related to providing 
electronic signatures on the notification. Should the Agency in the 
future decide to move forward with a facility notification requirement, 
we will repropose such requirement.

Section 112.1(e)--Proposed as Sec. 112.1(f)--Compliance With Other Laws

    Background. While today's rule is substantially similar to the 
current one, EPA suggested in the 1991 preamble that facility owners 
consider industry standards in preparing SPCC Plans. 56 FR 54617.
    Comments. State rules. Several States wrote to ask EPA to be as 
consistent with current State rules as possible. One industry commenter 
complained that EPA rules were more stringent than some State rules. 
Other industry commenters opposed either State or Federal regulation, 
or both.
    Industry standards. Several commenters wrote to urge that EPA 
incorporate industry standards into the rule, on the theory that if EPA 
wants to require these standards, they must be incorporated into the 
rule. Others wrote to urge the inclusion of specific standards, such as 
fire codes or steel tank codes.
    Response to comments. State rules. Section 311(o)(2) of the CWA 
specifically provides that nothing in section 311 ``shall be construed 
as preempting any State or political subdivision thereof from imposing 
any requirements or liability with respect to the discharge of oil * * 
*.'' We are aware that Federal rules often set the standard for State 
rules, and at least set a floor for State rules. Under CWA section 
311(o)(2), States are free to impose more stringent standards relating 
to prevention of oil discharges, or none at all. EPA encourages States 
to set up their own oil pollution prevention programs because we 
believe that oil pollution prevention efforts should be a joint 
Federal-State effort.
    Industry standards. Under this rule, a facility is required to at 
least consider the use of all relevant measures, including the use of 
industry standards, as a way to implement those measures. The 
requirement comes in the language of revised Sec. 112.3(d)(1)(iii) 
requiring the PE to attest that ``the Plan has been prepared in 
accordance with good engineering practice, including consideration of 
applicable industry standards, and with the requirements of this 
part.'' A facility should use industry standards whenever possible in 
preparing and implementing its SPCC Plan, and should discuss their use 
in Plans. While facility owners or operators should look to specific 
industry standards as a guide for preparing SPCC Plans, we do not 
believe that incorporating specific standards into this rule is 
appropriate. Such incorporation freezes standards into rules, which may 
swiftly become outdated or obsolete.
    Editorial changes and clarifications. The new introductory language 
is, ``This part establishes requirements for the preparation and 
implementation of Spill Prevention, Control, and Countermeasure (SPCC) 
Plans.'' The new language covers all SPCC requirements, both general 
and specific. That language replaces ``This part provides for * * *.'' 
The phrase ``Plans prepared in accordance with Secs. 112.7, 112.8, 
112.9, 112.10, and 112.11'' was eliminated because new introductory 
language makes it unnecessary.

Section 112.1(f)--Proposed as Sec. 112.1(g)--Plans for Exempted 
Facilities

    Background. This is a new section, proposed in 1993, that allows 
the Regional Administrators (RAs) to require preparation of entire an 
SPCC Plan, or applicable part, by the owner or operator of an otherwise 
exempted facility, that is subject to the jurisdiction of EPA under 
section 311(j) of the CWA. The proposal stems from the 1988 Interagency 
SPCC Task Force and subsequent GAO report, ``Inland Oil Spills'' (GAO/
RCED-89-65).
    Comments. Authority. One commenter called the proposal ``arbitrary 
and capricious'' and feared political use of the authority. Some 
commenters questioned EPA authority for the proposal.

[[Page 47071]]

    Standard to use authority. One commenter favored the proposal and 
suggested that we look at additional physical characteristics of the 
facility in order to make a determination to require the owner or 
operator to prepare an SPCC Plan. Other commenters asserted that the 
standards for requiring Plans need to be specified, or that ``good 
cause'' be the standard.
    Response Plans. One commenter urged a ``vastly abbreviated'' 
version of this section in the event that the Regional Administrator 
requires a small Appalachian facility to prepare a facility response 
plan in addition to an SPCC Plan, because the ``extensive requirements 
outlined in the appendices and attachments have little applicability'' 
to a small Appalachian oil field storage facility. The commenter added 
that the availability of secondary containment at most Appalachian 
facilities mitigates many of the requirements of the complete response 
plan which is directed towards large oil storage tanks.
    Appeals process. Other commenters called for an appeals process, 
and specification of time frames within which the RA must act.
    Response to comments. Authority. EPA believes that it has adequate 
authority under section 311 of the CWA to require any facility within 
its jurisdiction to prepare a Plan that could because of its location, 
cause a discharge as described in Sec. 112.1(b). This authority is 
broad enough to encompass the storage or use capacity of any exempted 
facility within EPA's jurisdiction, regardless of size.
    Standard to use authority. RAs may invoke this section to carry out 
the purposes of the Act on a case-specific basis when it is needed to 
prevent a discharge as described in Sec. 112.1(b), and thus protect the 
environment. While we expect to use this section sparingly, it is 
necessary to address gaps in other regulatory regimes that might best 
be remedied by requiring a facility to have an SPCC Plan. Factors the 
RAs may consider in making a determination that a facility needs an 
SPCC Plan include, but are not limited to, the physical characteristics 
of the facility, the presence of secondary containment, the discharge 
history of the facility, and the proximity of the facility to sensitive 
environmental areas such as wetlands, parks, or wildlife refuges. An 
example of the use of this section might be when a facility is exempted 
from SPCC rules because its storage capacity is below the regulatory 
threshold, but the facility has been the cause of repeated discharges 
as described in Sec. 112.1(b). The RA might require an entire Plan, or 
might only require a partial Plan addressing secondary containment, for 
example, to prevent future discharges as described in Sec. 112.1(b).
    Partial Plans. We clarify that the RA may require partial Plans to 
cover situations where the preparation of only a partial Plan may be 
necessary, such as to supplement an existing document other than a Plan 
or to address a particular environmental threat. The decision to 
require a Plan (or partial Plan) could be based on the presence of 
environmental concerns not adequately addressed under UST or NPDES 
regulations, or due to other relevant environmental factors. The 
section may be invoked when the RA determines it is necessary to 
``carry out the purposes of the Act.''
    The decision to require a partial Plan is separate from a decision 
to require an amendment to a Plan. In one case, the assumption is that 
a Plan doesn't exist; in the other, that an existing Plan needs 
amendment.
    Response Plans. Section 112.1(f) applies only to the total or 
partial preparation of an SPCC Plan. It does not authorize the Regional 
Administrator to require you to prepare a facility response plan. We 
have withdrawn a proposal (see 1993 proposed Sec. 112.7(d)(1)) which 
would have required you to prepare a response plan when your SPCC 
facility lacked secondary containment. Therefore, most facilities will 
incur no response planning costs. Instead, if your facility lacks 
secondary containment, you must prepare a contingency plan following 
the provisions of 40 CFR part 109, and otherwise comply with 
Sec. 112.7(d). As a result, requirements to prepare a facility response 
plan are contained solely in Sec. 112.20, and not Sec. 112.1(f).
    Appeals process. We agree that an appeals process is appropriate 
for this section. Therefore we have added a new paragraph (f)(5) to 
include such a process, and have provided time frames for the process. 
The appeals process is modeled upon current Sec. 112.4(f), which we 
reproposed in 1991 and have finalized today.
    Editorial changes and clarifications. We deleted the proposed 
requirement to ``submit'' a Plan in paragraph (f)(2), because we only 
require submission of Plans in certain circumstances, such as when 
there has been a discharge(s) as described in Sec. 112.1(b) over the 
threshold amount provided for in Sec. 112.4(a), and the RA believes 
that submission of the Plan is necessary. We do not require Plan 
submission as a general rule.

Section 112.2--Definitions

    Background. Definitions proposed in 1993 and 1999, and promulgated 
in the Facility Response Plan rule of 1994 and 2000 are reprinted in 
the rule for the convenience of the reader. No substantive changes were 
made to those definitions and they are not discussed further in this 
preamble, except where we made editorial changes in today's rule. The 
discussion for those editorial changes, and for proposed definitions 
that were not already finalized in the 1994 and 2000 FRP rule, follows.
Adverse Weather
    Editorial changes and clarifications. We have made slight editorial 
changes to this definition, none of which are substantive. In the first 
sentence, the phrase ``will be considered'' becomes ``must be 
considered.'' In the second sentence, the phrase ``as appropriate'' is 
placed in parentheses.
Alteration
    Background. In 1993, we proposed a definition of ``alteration'' in 
conjunction with the proposed rule for ensuring against brittle 
fracture. We proposed the definition of ``alteration'' to mean ``any 
work on a tank or related equipment involving cutting, burning, 
welding, or heating operations that changes the physical dimensions or 
configuration of a tank.''
    Comments. One commenter suggested that we conform the proposed 
definition of ``alteration'' with the API 653 definition, specifically 
deleting the phase ``or related equipment.''
    Response to comments. Related equipment. We agree with the 
commenter and will not include the term ``or related equipment'' in the 
definition to conform with API Standard 653, which does not include 
alterations of related equipment as a criterion for brittle fracture 
evaluation. In the preamble to the 1993 proposal, we gave examples of 
alteration that included the addition of manways and nozzles greater 
than 12-inch nominal pipe size and an increase or decrease in tank 
shell height. 58 FR 8843.
    Industry Standards. An industry standard that may be helpful in 
understanding the definition of ``alteration'' is API Standard 653, 
``Tank Inspection, Repair, Alteration, and Reconstruction.''
    Editorial changes and clarifications. ``Tank'' becomes 
``container.''
Breakout tank
    Background. We proposed this definition and the definition of 
``bulk storage tank'' in 1991 to clarify the distinction between 
facilities regulated

[[Page 47072]]

by DOT and EPA. Breakout tanks are used mainly to compensate for 
pressure surges or to control and maintain pressure through pipelines. 
They are also sometimes used for bulk storage. These tanks are 
frequently in-line, and may be regulated by EPA, DOT, or both. When a 
breakout tank is used for both storage and for pipeline control, it 
becomes in itself a ``complex,'' and is regulated as such. See the 
discussion on ``complexes'' in today's preamble at 
Sec. 112.1(d)(1)(ii).
    Comments. A number of commenters suggested that EPA adopt the DOT 
definition of breakout tank. Another commenter asked for guidance as to 
which agency, DOT or EPA, regulates such tanks.
    Response to comments. On the suggestion of commenters, EPA has 
adopted a modified version of the DOT definition in 49 CFR 195.2. This 
revision promotes consistency in the DOT and EPA definitions to aid the 
regulators and regulated community. We modified the DOT definition by 
substituting the word ``oil'' for ``hazardous liquid,'' because our 
rules apply only to oil. We also use in the definition the term 
``container'' rather than just ``tank'' to cover any type of container. 
This terminology is consistent with other terminology used in this 
rule.
    A breakout tank that is used only to relieve surges in an oil 
pipeline system or to receive and store oil transported by a pipeline 
for reinjection and continued transportation by pipeline is subject 
only to DOT jurisdiction. When that same breakout tank is used for 
other purposes, such as a process tank or as a bulk storage container, 
it is no longer solely within the definition of breakout tank, and may 
be subject to EPA or other jurisdiction with the new use.
    EPA and DOT also signed a joint memorandum dated February 4, 2000, 
clarifying regulatory jurisdiction on breakout tanks. That memorandum 
is available to the public upon request. It is also available on our 
Web site at http://www.epa.gov/oilspill under the ``What's New'' 
section.
Bulk Storage Container--Formerly Bulk Storage Tank
    Background. Along with ``breakout tank,'' we proposed this 
definition in 1991 to help clarify the distinctions between facilities 
regulated by EPA and those regulated by DOT. The proposed definition 
was originally for ``bulk storage tank.'' As explained below, we 
changed the definition to ``bulk storage container.''
    Comments. Many electric utility commenters urged that EPA 
explicitly exclude electrical equipment from the definition because 
such equipment is not bulk storage. Other commenters asked for a 
minimum size to which the definition should apply.
    Response to comments. We agree that electrical equipment is not 
bulk storage. See the above discussion on the applicability of the rule 
to electrical and other operating equipment under Sec. 112.1(b). See 
also the definition of ``bulk storage container'' in Sec. 112.2. For a 
discussion of minimum size containers to which the rule applies, see 
the discussion under Sec. 112.1(d)(2)(ii).
    Editorial changes and clarifications. ``Tank'' becomes 
``container'' because ``container'' is more accurate. Many containers 
storing oil are not tanks, but provide bulk storage. A bulk storage 
container may be either aboveground, partially buried, bunkered, or 
completely buried.
    The definition of ``bulk storage container'' adopted in today's 
rule should not be confused with the definitions of ``container'' used 
in several fire codes. Sometimes those codes limit a container to one 
below a certain size. See for example, the BOCA National Fire 
Prevention Code, section F-2302.1 (1999) and NFPA 30 section 1-6 
(1996). The definition adopted in today's rule is broader than the 
definitions in the codes in that it is not limited to a particular 
amount of storage capacity.
    We also clarify in today's rule that oil-filled electrical, 
operating, or manufacturing equipment is not a bulk storage container.
Bunkered Tank
    Background. We proposed this definition in 1991 to clarify that 
bunkered tanks are a subset of partially buried tanks, and as such, 
subject to part 112 as aboveground tanks.
    Comments. One commenter wrote that the definition is 
``undecipherable and should be rewritten.'' The commenter wrote that 
the definition should be, ``Bunkered tank means a partially buried 
tank, the portion of which lies above grade is covered with earth, 
sand, gravel, asphalt, or other material.''
    Response to comments. EPA agrees that the commenter's proposed 
definition is clearer, and we have used it with slight editorial 
changes.
    Editorial changes and clarifications. We added a sentence to the 
definition noting that bunkered tanks are a subset of aboveground 
storage containers for purposes of this part.
Completely Buried Tank--Proposed as ``Underground Storage Tank''
    Background. In 1991, we proposed adding a definition for 
``underground storage tank.'' It differed from the Underground Storage 
Tank (UST) program definition in 40 CFR part 280 because it excluded 
tanks which are partially buried or bunkered, as well as some other 
tanks or containers included within the part 280 definition, such as 
containers storing certain hazardous substances. Partially buried and 
bunkered tanks still have a potential to discharge oil into navigable 
waters, adjoining shorelines, or affecting natural resources. 
Therefore, we proposed to retain those tanks within our regulatory 
jurisdiction, while we proposed to exclude all completely buried tanks 
storing petroleum that are subject to all of the technical requirements 
of the UST program (40 CFR part 280 or a State program approved under 
40 CFR part 281).
    Comments. Consistency with the definition of underground tanks in 
40 CFR part 280. One commenter supported the proposal. A number of 
commenters thought that the definitions of underground tanks in parts 
112 and 280 should be consistent.
    Vaulted tanks. Commenters divided on whether subterranean vaulted 
tanks should be considered ASTs or USTs. The commenter opposing the 
treatment of subterranean vaulted tanks as ASTs in the UST definition 
argued that discharges from those tanks pose no threat to the 
environment or public health.
    Response to comments. Consistency with the definition of 
underground tanks in 40 CFR part 280. We disagree that the scope of the 
part 112 exclusion for underground tanks should be consistent with the 
scope of the definition of ``underground storage tank'' in part 280. 
The programs are designed for different purposes, therefore, the 
definitions used will necessarily differ. To eliminate confusion with 
the part 280 definition, we have changed the proposed part 112 
definition of ``underground storage tank'' to ``completely buried 
tank'' in this final rule.
    Part 280 includes within its UST definition tanks which have a 
volume up to ninety percent above the surface of the ground, which are 
considered aboveground tanks for part 112 purposes. Part 280 also 
regulates underground storage tanks containing hazardous substances, 
while the SPCC program regulates only facilities storing or using oil 
as defined in CWA section 311. The SPCC program regulates

[[Page 47073]]

facilities with relatively large completely buried storage capacity, 
while the bulk of facilities regulated under part 280 are small 
capacity facilities such as gasoline filling stations. The SPCC program 
also regulates other types of containers and facilities which part 280 
excludes, such as: tanks used for storing heating oil for consumptive 
use on the premises where stored; certain pipeline complexes where oil 
is stored; and, oil-water separators.
    Vaulted tanks. Aboveground vaulted tanks are clearly ASTs. While 
subterranean vaulted tanks may be completely below grade, they may not 
be completely covered with earth. Because of their design, they pose a 
threat of discharge into the environment, and are thus excluded from 
our definition of completely buried tank. Subterranean vaulted tanks 
are also excluded from the part 280 UST definition of underground tank 
if the storage tank is situated upon or above the surface of the floor 
in an underground are providing enough space for physical inspection of 
the exterior of the tank. Therefore, if subterranean tanks were 
excluded from our definition of completely buried tank, they would 
likely not be regulated at all, and thereby be likely to pose a greater 
threat to the environment.
    Other completely buried tanks excluded from the part 280 UST 
definition. Tanks in underground rooms or above the floor surface, or 
in other underground areas such as basements, cellars, mine workings, 
drifts, shafts, or tunnels are also not considered USTs for purposes of 
the part 280 definition. The purpose of the part 112 definition is to 
clarify that these are tanks that are technically underground but that, 
in a practical sense, are no different from aboveground tanks. They are 
situated so that, to the same extent as tanks aboveground, physical 
inspection for leaks is possible. Also, some of these tanks are 
designed such that in case of a discharge, oil would escape to 
navigable waters or adjoining shorelines, a result which our program 
seeks to prevent.
    Editorial changes and clarifications. The words ``completely below 
grade and * * *'' were added to the first sentence of the definition. 
The purpose of that revision was to distinguish completely buried tanks 
from partially buried and bunkered tanks, which break the grade of the 
land, but are not completely below grade. We further clarify that such 
tanks may be covered not only with earth, but with sand, gravel, 
asphalt, or other material. The clarification brings the definition 
into accord with the coverings noted in the definition of ``bunkered 
tank.'' In the second sentence, the word ``subterranean'' was deleted 
from ``subterranean vaults'' because all vaulted tanks, whether 
subterranean or aboveground, are counted as aboveground tanks for 
purposes of this rule.
Contiguous Zone
    Background. The definition of ``contiguous zone'' was proposed in 
1991 to conform with 1978 amendments to the CWA, and the 1990 
amendments to the National Oil and Hazardous Substances Pollution 
Contingency Plan (NCP) dealing with the scope of discharges. EPA 
received no substantive comments. Thus, we have finalized the proposed 
definition.
    The contiguous zone is the area that extends nine miles seaward 
from the outer limit of the territorial sea. A presidential 
proclamation of December 17, 1988 (No. 5928, 54 FR 777, January 9, 
1989) extended the territorial seas of the United States to 12 nautical 
miles from the baselines of the United States as determined in 
accordance with international law. However, the proclamation provided 
that nothing therein ``extends or otherwise alters existing federal or 
state law or any jurisdiction, rights, legal interests, or obligations 
derived therefrom * * *.''
Contract or Other Approved Means
    Editorial changes and clarifications. We corrected the title of the 
definition to read ``contract or other approved means,'' in place of 
``contract or other approved.'' We also changed some plural references 
to singular ones.
Discharge
    Background. The 1991 proposed changes to the definition of 
``discharge'' reflected changes to the statutory definition in the 1978 
amendments to the CWA. For clarity, the words ``of oil'' were added in 
the first sentence because the definition applies only to discharges of 
oil.
    Comments. One commenter asked for a clarification of the term 
``discharge.'' The commenter asked whether a drop of diesel fuel that 
fell onto the outside casing of a tank during refilling would be 
considered a ``discharge,'' even if the oil did not reach the ground. 
Other commenters recommended that the definition include at least an 
imminent danger that the spilled material would reach a navigable 
waterway. Another commenter asked EPA to exempt from the definition 
those discharges regulated under the CWA, such as National Pollutant 
Discharge Elimination System (NPDES) discharges. The rationale was that 
any potential environmental impacts of these discharges have been 
considered in the issuance of a facility's NPDES permit and there is no 
reason to subject such facilities to dual regulation.
    Response to comments. A discharge includes, but is not limited to, 
any ``spilling, leaking, pumping, pouring, emitting, emptying, or 
dumping,'' of oil. A discharge as described in Sec. 112.1(b) need not 
reach the level of an imminent danger to affected lands, waters, or 
resources to be a discharge. It includes any spilling, leaking, 
pumping, pouring, emitting, emptying, or dumping of any amount of oil 
no matter where it occurs. It may not be a reportable discharge under 
40 CFR part 110 if oil never escapes the secondary containment at the 
facility and is promptly cleaned up. If the discharge escapes secondary 
containment, it may become a discharge as described in Sec. 112.1(b), 
and if that happens, the discharge must then be reported to the 
National Response Center.
    Foreseeable or chronic point source discharges that are permitted 
under section 402 of the CWA, and that are either due to causes 
associated with the manufacturing or other commercial activities in 
which the discharger is engaged or due to the operation of the 
treatment facilities required by the NPDES permit, are to be regulated 
under the NPDES program. Other oil discharges in reportable quantities 
are subject to the requirements of section 311 of the CWA. Such spills 
or discharges are governed by section 311 even where the discharger 
holds a valid and effective NPDES permit under CWA section 402. 
Therefore, a discharge of oil to a publicly owned treatment work (POTW) 
would not be a discharge under the Sec. 112.2 definition if the 
discharge is in compliance with the provisions of the permit; or 
resulted from a circumstance identified and reviewed and made a part of 
the public record with respect to a permit issued or modified under 
section 402; or if it were a continuous or anticipated intermittent 
discharge from a point source, identified in a permit or permit 
application under section 402, which is caused by events occurring 
within the scope of relevant operating or treatment systems. 33 U.S.C. 
1321(a)(2); 40 CFR 117.12. Otherwise, the discharge is subject to the 
provisions of section 311 of the CWA as well as the unpermitted 
discharge prohibition of section 301(a) of the CWA. 33 U.S.C. 1311(a).
    Editorial changes and clarifications. We have revised the citation 
for the River and Harbor Act of 1899 so that it refers only to the U.S. 
Code, and have

[[Page 47074]]

deleted the reference to the Statutes at Large.
Facility
    Background. Because we regulate facilities in the SPCC rule, we 
proposed a definition of ``facility'' in 1991. It is based on the 
Memorandum of Understanding (MOU) between the Secretary of DOT and the 
EPA Administrator, dated November 24, 1971 (36 FR 24080). A discussion 
of the types of facilities covered is found in Appendix A to this rule.
    Comments. Facility boundaries. One commenter asked for 
clarification as to whether the facility is the petroleum storage site 
or a single tank at the site.
    Electrical or operational equipment. Utility commenters argued that 
electrical equipment is not a facility because no oil is being stored 
in the equipment.
    Buried pipelines, gathering lines, flowlines, waste treatment 
equipment. One commenter urged that buried pipelines at mining sites 
should be excluded from the definition because such pipelines are often 
put in place without recording their location. The commenter added that 
typically the lines are emptied and abandoned as part of final 
reclamation. Other commenters urged the exclusion of gathering lines 
and flowlines from the definition because of the cost of providing 
secondary containment and contingency planning for such lines. Another 
commenter protested the inclusion of waste treatment as a possible 
activity covered under the definition, and therefore the rule.
    Mobile or fixed facilities. One commenter urged that mobile 
equipment be excluded from the definition because the commenter 
believed that the SPCC Plan would otherwise have to be amended each 
time the mobile equipment is moved.
    Response to Comments. Facility boundaries. A facility includes any 
building, structure, installation, equipment, pipe or pipeline in oil 
well drilling operations, oil production, oil refining, oil storage, 
and waste treatment, or in which oil is used at a site, whether it is 
mobile or fixed. It may also include power rights of way connected to 
the facility. The extent of the facility will vary according to the 
circumstances of the site. It may be as small as a single container or 
as large as all of the structures and buildings on a site. Some 
specific factors to use in determining the extent of a facility may be 
the ownership or operation of those buildings, structures, equipment, 
installations, pipes or pipelines, or the types of activities being 
carried on at the facility.
    Electrical or operational equipment. We disagree with commenters 
who maintained that electrical equipment ``using'' oil as opposed to 
``storing'' it should not fall within the definition of ``facility'' in 
part 112. Section 311(j)(1)(C) of the CWA, which authorizes EPA to 
promulgate the SPCC rule, does not distinguish between the storage and 
the usage of oil. The section simply authorizes EPA, as delegated by 
the President, to establish ``requirements to prevent discharges of oil 
* * * from onshore and offshore facilities, and to contain such 
discharges * * *.'' 33 U.S.C. 1321(j)(1)(C). Nor do the definitions of 
``onshore facility'' or ``offshore facility'' in sections 311(a)(10) of 
the CWA distinguish between the use or storage of oil. Although the 
definition of ``facility'' in section 1001(9) of the OPA is limited by 
the ``purpose'' of the facility, no such limitation appears in CWA 
section 311. Moreover, EPA believes that although much of the 
electrical equipment may arguably ``use'' oil, in effect the oil is 
``stored'' in the equipment because it remains in the equipment for 
such long time frames. We added language to the definition to clarify 
that such types of equipment are facilities subject to the SPCC rule 
whether they are storing or using oil. Therefore, we revised the 
definition to include the words ``or in which oil is used.'' However, 
we note that a facility which contains only electrical equipment is not 
a bulk storage facility.
    Buried pipelines, gathering lines, flowlines, waste treatment 
equipment. Buried pipelines that carry oil at mining sites are part of 
a facility unless they are permanently closed as defined in Sec. 112.2. 
Such pipelines may otherwise be the source of a discharge as described 
in Sec. 112.1(b). Likewise, the same rationale applies to gathering 
lines and flowlines, and waste treatment equipment. Note that any 
facility or part thereof used exclusively for wastewater treatment and 
not to satisfy any part 112 requirement is exempted from the rule. The 
production, recovery, or recycling of oil is not considered wastewater 
treatment for purposes of the rule. See Sec. 112.1(d)(6).
    While such gathering lines, flowlines, and waste treatment 
equipment are subject to secondary containment requirements, the 
appropriate method of secondary containment is an engineering question. 
Double-walled piping may be an option, but is not required by these 
rules. The owner or operator and Professional Engineer certifying the 
Plan should consider whether pursuant to good engineering practice, 
double-walled piping is the appropriate method of secondary containment 
according to good engineering practice. In determining whether to 
install double-walled piping versus an alternative method of secondary 
containment, you could consider such factors as the additional 
effectiveness of double-walled piping in preventing discharges, the 
technical aspects of cathodically protecting any buried double-walled 
piping system, the cost of installing double-walled pipe, and the 
potential fire and safety hazards of double-walled pipes. Earthen or 
natural structures may be acceptable if they contain and prevent 
discharges as described in Sec. 112.1(b), including containment that 
prevents discharge of oil through groundwater that might cause a 
discharge as described in Sec. 112.1(b). What is practical for one 
facility, however, might not work for another.
    Mobile or fixed facilities. Either mobile or fixed equipment might 
be the source of a discharge as described in Sec. 112.1(b), and 
therefore both are included within the definition of ``facility.'' 
Section 112.3(c) of this rule already provides that it is not necessary 
to amend your Plan each time a mobile facility moves to a new site.
    Editorial changes and clarifications. In the first sentence we 
added the words ``oil gathering, oil processing, oil transfer, oil 
distribution'' to the list of activities listed. The added activities 
track the activities listed in Sec. 112.1(b). We also clarify that a 
vessel or a public vessel is not a facility or part of a facility. We 
deleted the word ``may'' in the second sentence of the definition 
regarding site-specific factors of facility boundaries, because it is 
redundant with the inclusion of the words, ``including, but not limited 
to.''
Fish and Wildlife and Sensitive Environments
    Editorial changes and clarifications. We made four editorial 
changes. We deleted the word ``either'' in the first sentence because 
it is unnecessary. ``Endangered/threatened species'' becomes 
``endangered or threatened species.'' We also deleted the colon in the 
last sentence because it is unnecessary. ``Discharges of oil'' becomes 
``discharges.''
Maximum Extent Practicable
    Editorial changes and clarifications. In the first sentence the 
phrase ``the limitations used to determine'' becomes ``within the 
limitations used to determine.'' In the beginning of second sentence, 
``It considers * * *.'' becomes ``It includes* * *.''

Navigable Waters
    Background. We proposed a revision of the definition of ``navigable 
waters'' in 1991. The rationale was to have the part 112 definition 
track the definition of ``navigable waters'' in 40 CFR part 110, which 
deals with the discharge of oil.
    Comments. Clarification of the meaning of navigable waters, maps. A 
number of commenters asked for a clarification of the definition of 
navigable waters because of the difficulty of determining which waters 
fall within the definition. Some asked for EPA maps to aid in this 
determination.
    Navigability, legal authority. Other commenters believed that the 
definition related to navigability. Some thought the definition was 
legally unsupportable because it is so broad. One commenter suggested 
that the term be limited to unobstructed streams that free flow at 
least fourteen consecutive days per year.
    Wetlands. Another commenter believed that the definition should not 
apply to wetlands because SPCC protections are not needed when wetlands 
are regulated under a permit program.
    Response to comments. Clarification of the meaning of navigable 
waters, maps. In this definition, we clarify what we mean by navigable 
waters by describing the characteristics of navigable waters and by 
listing examples of navigable waters. We also note in the definition 
that certain waste treatment systems are not navigable waters.
    We are unable to provide a map to identify all navigable waters 
because not all such waters have been identified on a map. However, the 
rule provides guidelines as to where such waters may be found.
    Navigability, legal authority. Navigable waters are not only waters 
on which a craft may be sailed. Navigable waters include all waters 
with a past, present, or possible future use in interstate or foreign 
commerce, including all waters subject to the ebb and flow of the tide. 
Navigable waters also include intrastate waters which could affect 
interstate or foreign commerce. The case law supports a broad 
definition of navigable waters, such as the one published today, and 
that definition does not necessarily depend on navigability in fact.
    Wetlands. We disagree that SPCC regulation of wetlands is 
redundant. The definition includes wetlands, as defined in Sec. 112.2 
and discussed below, because wetlands are waters of the United States. 
Different programs serve different purposes, and merely because an 
activity or function is regulated for one purpose (for example, NPDES) 
does not mean that regulation for another purpose is redundant. The 
purpose of a permit discharge system is waste treatment and management. 
The purpose of the SPCC rule is oil pollution prevention.
Offshore Facility
    Background. EPA proposed in 1991 to revise the definition of 
``offshore facility'' to conform with the CWA and NCP definitions.
    Comments. EPA or DOI jurisdiction. One commenter noted that if the 
definition of offshore facility is taken in context with the definition 
of navigable waters, then many facilities traditionally subject to EPA 
jurisdiction would become subject to DOI authority.
    CWA definition. Another commenter suggested that the EPA definition 
should instead be that contained in CWA section 311(a)(11).
    Response to comments. EPA or DOI jurisdiction. The 1994 Memorandum 
of Understanding between DOI, DOT, and EPA addresses the jurisdictional 
issue to which the commenter refers, transferring to EPA those non-
transportation-related offshore facilities landward of the coastline.
    CWA definition. EPA agrees with the commenter urging that the EPA 
definition track the statutory definition. The part 112 definition, 
except for minor editorial changes, is identical to the CWA definition. 
There is no difference between the substance of the part 112 definition 
and the CWA definition.
    Editorial changes and clarifications. Permanently moored vessels 
and other former transportation equipment. We also note that barges 
which store oil, and have been determined by the Coast Guard to be 
permanently moored, are no longer vessels, but storage containers that 
are part of an offshore facility. Likewise, a container, whether 
onshore or offshore, which was formerly used for transportation, such 
as a truck or railroad car, which now is used to store oil, is no 
longer used for a transportation purpose, and is a bulk storage 
container.
Oil
    Background. In 1991, EPA reprinted the definition of oil without 
suggesting any changes. In response to Edible Oil Regulatory Reform Act 
(EORRA) of 1995 (33 U.S.C. 2720) requirements, we have reworded the 
definition to include the categories of oil included in EORRA. Those 
categories are: (1) Petroleum oils, (2) animal fats and vegetable oils; 
and, (3) other non-petroleum oils and greases. Animal fats include 
fats, oils, and greases of animal origin (for example, lard and 
tallow), fish (for example, cod liver oil), or marine mammal origin 
(for example, whale oil). Vegetable oils include oils of vegetable 
origin, including oils from seeds, nuts, fruits, and kernels. Examples 
of vegetable oils include: corn oil, rapeseed oil, coconut oil, palm 
oil, soy bean oil, sunflower seed oil, cottonseed oil, and peanut oil. 
Other non-petroleum oils and greases include coal tar, creosote, 
silicon fluids, pine oil, turpentine, and tall oils. Petroleum oils 
include crude and refined petroleum products, asphalt, gasoline, fuel 
oils, mineral oils, naphtha, sludge, oil refuse, and oil mixed with 
wastes other than dredged spoil.
    EORRA requires that Federal agencies establish separate classes for 
at least these three types of oils. It further requires agencies to 
differentiate between those classes of oil in relation to their 
environmental effects, and their physical, chemical, biological, and 
other characteristics. EPA has provided new subparts within part 112 to 
facilitate differentiation between the categories of oil listed in 
EORRA. In an advance notice of proposed rulemaking, published on April 
8, 1999 (64 FR 17227), we requested ideas on how to differentiate among 
the SPCC requirements for facilities storing or using the various 
categories of oil. These ideas for further differentiation will be 
considered in a future rulemaking.
    Today's amendments to the definition and the creation of subparts 
have no effect on information collection, because we already include 
all types of oil in our information collection burden calculations. 
Similarly, the definition imposes no new requirements, because all oils 
have always been subject to the substantive requirements of the rule.
    Comments. What is oil. Several commenters favored the proposed 1991 
definition, which is identical to the current definition. Some asked 
for clarification as to its scope, particularly in reference to animal 
and vegetable oils, synthetic oils, mineral oils, and petroleum 
derivatives.
    Specific substances. Others asked about specific substances like 
aromatic hydrocarbons and asphaltic cement. One commenter asked if 
bilge water is oil.
    Authority. Some commenters suggested that EPA's authority did not 
extend beyond petroleum-based oils.
    Exclusions. Some commenters sought exclusions from the definition, 
generally based on contentions that certain oils (such as vegetable 
oils) are not harmful

[[Page 47076]]

to the environment if discharged. One commenter suggested a definition 
based on the liquidity of oil, founded on a rationale that solid or 
gaseous oils do not pose a threat to waters of the United States when 
discharged at a fixed facility. Another commenter urged that we exempt 
refined petroleum products from the definition because releases from 
many of these products are regulated by other statutes, such as the 
Solid Waste Disposal Act. One State commenter noted that animal and 
vegetable oils are not subject to regulation under that State's 
statutes regulating oil.
    Oil mixed with wastes or hazardous substances. Others asked for 
clarification as to whether mixed substances, used oil, and waste oils 
were oil.
    Part 280 definition. One commenter noted the difference in 
definitions between the part 112 definition and the definition in 40 
CFR part 280.
    Response to comments. What is oil. EPA interprets the definition of 
oil to include all types of oil, in whatever form, solid or liquid. 
That includes synthetic oils, mineral oils, vegetable oils, animal 
fats, petroleum derivatives, etc.
    Specific substances. As to certain specific substances, asphaltic 
cement is oil because it is a petroleum-based product and exhibits oil-
like characteristics. A discharge of asphaltic cement may violate 
applicable water quality standards, or cause a film or sheen or 
discoloration of the water or adjoining shorelines or cause a sludge or 
emulsion to be deposited beneath the surface of the water or upon 
adjoining shorelines. Aromatic hydrocarbons may or may not be oil, 
depending on their physical characteristics and environmental effects. 
Some aromatic hydrocarbons are hazardous substances. Bilge water that 
contains sufficient oil such that its discharge would violate the 
standards set out in 40 CFR 110.3 is considered oil. The percentage of 
oil concentration in the water is not determinative for the purpose of 
the definition or the discharge standards.
    Authority. We disagree that our authority only extends to 
petroleum-based oils. Our interpretation is consistent with 
Congressional intent as expressed in section 311(a)(1) of the CWA, 
which extends to all types of oils in any form. EPA's definition tracks 
that statutory definition. Our revised definition also reflects EORRA 
requirements for differentiation. EORRA did not expand or contract the 
universe of substances that are oils, it only required differentiation, 
when necessary, between the requirements for facilities storing or 
using different types of oil.
    Exclusions. While States may choose to regulate all oils or some 
oils, the CWA definition is designed to prevent the discharge of all 
oils.
    A definition based on liquidity would exclude solid oils, such as 
certain animal fats, a result that would be inconsistent with 
Congressional intent. Concerning gaseous oils, see our discussion on 
Highly volatile liquids below.
    While releases or discharges of some refined petroleum products may 
be regulated under the Solid Waste Disposal Act as waste products, that 
program is dedicated more to waste management, and does not regulate 
storage of non-waste oil.
    All oils, including animal fats and vegetable oils, can harm the 
environment in many ways. Oil can coat the feathers of birds, the fur 
of mammals and cause drowning and hypothermia and increased 
vulnerability to starvation and predators from lack of mobility.
    Oils can act on the epithelial tissue of fish, accumulate on gills, 
and prevent respiration. The oil coating of surface waters can 
interfere with natural processes, oxygen diffusion/reaeration and 
photosynthesis. Organisms and algae coated with oil may settle to the 
bottom with suspended solids along with other oily substances that can 
destroy benthic organisms and interfere with spawning areas.
    Oils can increase biological or chemical oxygen demand and deplete 
the water of oxygen sufficiently to kill fish and other aquatic 
organisms.
    Oils can cause starvation of fish and wildlife by coating food and 
depleting the food supply. Animals that ingest large amounts of oil 
through contaminated food or preening themselves may die as a result of 
the ingested oil. Animals can also starve because of increased energy 
demands needed to maintain body temperature when they are coated with 
oil.
    Oils can exert a direct toxic action on fish, wildlife, or their 
food supply. Oils can taint the flavor of fish for human consumption 
and cause intestinal lesions in fish from laxative properties. Tainted 
flavor of fish used for human consumption and the causation of rancid 
odors are public health or welfare concerns within the scope of our 
rules. Tainted flavor of fish used for human consumption may indicate a 
disease in the fish which could render them inedible and thus have a 
substantial impact on the fishermen who harvest them and communities 
who may rely on them for a food supply.
    Oils can foul shorelines and beaches. Oil discharges can create 
rancid odors. Rancid odors may cause both health impacts and 
environmental impacts. For example, the 1991 Wisconsin Butter Fire and 
Spill resulted in a discharge of melted butter and lard. After the 
cleanup was largely completed, the Wisconsin Department of Natural 
Resources declared as hazardous substances the thousands of gallons of 
melted butter that ran offsite and the mountain of damaged and charred 
meat products spoiling in the hot sun and creating objectionable odors. 
The Wisconsin DNR stated that these products posed an imminent threat 
to human health and the environment. 62 FR 54526.
    Highly volatile liquids. We do not consider highly volatile liquids 
that volatilize on contact with air or water, such as liquid natural 
gas, or liquid petroleum gas, to be oil. Such substances do not violate 
applicable water quality standards, do not cause a reportable film or 
sheen or discoloration upon the surface of water or adjoining 
shorelines, do not cause a sludge or emulsion to be deposited beneath 
the surface of the water or upon adjoining shorelines, and are not 
removable. Therefore, there would be no reportable discharge as 
described in 40 CFR 110.3.
    Oil mixed with wastes or hazardous substances. Oil means oil of any 
kind or in any form, including, but not limited to: fats, oils, or 
greases of animal, fish, or marine mammal origin; vegetable oils, 
including oils from seeds, nuts, fruits, or kernels; and, other oils 
and greases, including petroleum, fuel oil, sludge, synthetic oils, 
mineral oils, oil refuse, or oil mixed with wastes other than dredged 
spoil.
    Part 280 definition. The definition of petroleum in 40 CFR part 280 
is a subset of the part 112 definition of ``oil.'' The part 112 
definition of oil is broader than the part 280 definition of petroleum 
because part 112 regulates all types of oils, whereas part 280 
regulates only petroleum.
Oil drilling, production, or workover facilities (offshore)
    Background. See the definition of ``production facility,'' into 
which this definition has been merged.
Oil Production Facilities (Onshore)
    Background. See the definition of ``production facility,'' into 
which this definition has been merged.
Onshore Facility
    Background. As proposed, we deleted as unnecessary surplus the 
reference to the facility not being transportation-

[[Page 47077]]

related. There were no substantive comments.
Partially Buried Tank
    Background. In 1991, EPA proposed the definition of ``partially 
buried tank'' to clarify the distinction between partially buried tanks 
and underground storage tanks. We have renamed underground tanks in 
this rule as ``completely buried tanks,'' i.e., those tanks completely 
covered with earth. Partially buried tanks are subject to the SPCC rule 
the same as aboveground containers.
    Comments. One commenter wrote that the definition as proposed was 
``undecipherable'' and should be rewritten. That commenter suggested 
another definition for clarity. Two other commenters suggested that we 
adopt the part 280 UST definition for partially buried tank, which 
includes any tank system such as tank and piping which has a volume of 
10 percent or more beneath the surface of the ground.
    Response to comments. We agree that the definition could be clearer 
and have clarified it. We decline to adopt the part 280 UST definition 
(at 40 CFR 280.12) and to classify partially buried tanks as completely 
buried tanks, because they are not. The UST definition might also 
exclude some tanks or containers which would be covered by the SPCC 
definition. The UST definition includes tanks whose volume (including 
the volume of underground pipes connected thereto) are 10 percent or 
more beneath the surface of the ground. The SPCC definition of 
``partially buried tank'' contains no volume percentage and applies to 
any tank that is partially inserted or constructed in the ground, but 
not entirely below grade, and not completely covered with earth.
    Editorial changes and clarifications. We clarify that partially 
buried tanks may be covered not only with earth, but with sand, gravel, 
asphalt, or other material. The clarification brings the definition 
into accord with the coverings noted in the definition of ``bunkered 
tank.'' We added a sentence to the definition noting that partially 
buried tanks are considered aboveground storage containers for purposes 
of this part.
Permanently Closed
    Background. EPA proposed a definition of ``permanently closed'' in 
1991 to clarify the scope of facilities and tanks or containers 
excluded from coverage under the SPCC rule. Permanently closed 
containers are those containers which are no longer capable of storing 
or using oil. Permanently closed facilities are those facilities which 
are no longer capable of storing or using oil.
    In permanently closed containers and facilities, physical changes 
have been made so that storage capacity or use is rendered impossible. 
Therefore, the definition describes those changes which must have 
occurred before a container or facility is ``permanently closed.''
    Comments. In general. Several commenters favored the proposed 
definition. Others opposed it as unnecessary, believing that ``if a 
tank is not used for the storage of oil, it simply is not subject to 
the provisions of the SPCC regulations.'' Finally, several commenters 
suggested that the definition specifically exclude temporarily closed 
tanks.
    Waste disposal. Several commenters urged that the part of the 
proposal that dealt with waste disposal be deleted because waste 
disposal is already covered under other programs and should not be a 
concern of spill prevention unless flowable oil is part of the waste.
    Non-oil products. One commenter asked for clarification that a 
container which is no longer used for oil but is used for some non-oil 
product be considered permanently closed.
    Connecting lines. Another commenter asked for clarification as to 
the meaning of connecting lines. The commenter assumed that connecting 
lines means the sections of pipe that run between the tank and the 
nearest block valve.
    Explosive vapors. Numerous commenters urged that EPA delete any 
rules dealing with explosive vapors on the theory that such vapors are 
regulated by the Occupational Health and Safety Administration (OSHA) 
program and other programs. Many of these same commenters suggested 
that placing a sign on a tank indicating that it has been freed of gas 
is not a good safety practice because gas might subsequently build up 
within the tank with catastrophic results.
    Retroactivity. Several commenters suggested that the requirements 
for a tank to be permanently closed should not be applied retroactively 
to tanks previously removed from service. The rationale was that the 
cost would be prohibitive, although commenters did not provide specific 
cost estimates, and that it might cause confusion as to which tanks 
would have to be included in facility capacity calculations. These 
commenters also asserted that such tanks have been abandoned and empty, 
sometimes for many years, and pose no threat of discharge.
    Response to comments. In general. A definition is necessary to 
clarify when a container is permanently closed and no longer used for 
the storage of oil. Containers that are only closed temporarily may be 
returned to storage purposes and thus may present a threat of 
discharge. Therefore, they will continue to be subject to the rule.
    Waste disposal. Reference to waste disposal in accordance with 
Federal and State rules in proposed Sec. 112.2(o)(1) was deleted as 
unnecessary surplus. EPA agrees that other programs adequately handle 
waste disposal.
    Non-oil products. Containers that store products other than oil and 
never store oil, are not subject to the SPCC rule whether they are 
``permanently closed'' as defined or not. If the containers sometimes 
store oil and sometimes store non-oil products, they are subject to the 
rule.
    Connecting lines. We agree with the commenter's assumed definition 
of connecting lines. Connecting lines that have been emptied of oil, 
and have been disconnected and blanked off, are considered permanently 
closed.
    Explosive vapors. We deleted proposed Sec. 112.2(o)(2) on the 
suggestion of commenters that references to explosive vapors are an 
OSHA matter and inappropriate for EPA rules. We modified proposed 
Sec. 112.2(o)(3) to eliminate the reference to signs warning that 
``vapors above the LEL are not present,'' because the operator cannot 
guarantee that warning remains correct. To help prevent a buildup of 
explosive vapors, we have revised the definition to provide that 
ventilation valves need not be closed. We agree with commenters that a 
sign might be misleading and dangerous.
    Retroactivity. We believe that containers that have been 
permanently closed according to the standards prescribed in the rule 
qualify for the designation of ``permanently closed,'' whether they 
have been closed before or after the effective date of the rule. 
Containers that cannot meet the standards prescribed in the rule will 
not qualify as permanently closed. We disagree that the cost of such 
closure is prohibitive. We have simplified the proposal and deleted the 
proposed requirement to render the tank free of explosive vapor. 
Therefore, costs are lower. To clarify when a container has been 
closed, we have amended the rule to require that the sign noting 
closure show the date of such closure. The date of such closure must be 
noted whether it occurred before or after the effective date of this 
provision. Some States and localities require a permit for tank 
closure. A document noting a State closure inspection may serve as

[[Page 47078]]

evidence of container closure if it is dated.
    Industry standards. Industry standards that may be useful to effect 
the permanent closure of containers or facilities include: (1) National 
Fire Protection Association (NFPA) 30, ``Flammable and Combustible 
Liquids Code''; (2) Building Officials and Code Administrators 
International (BOCA), ``National Fire Prevention Code''; (3) American 
Petroleum Institute (API) Standard 2015, ``Safe Entry and Cleaning of 
Petroleum Storage Tanks''; and, (4) API Recommended Practice 1604, 
``Removal and Disposal of Used Underground Petroleum Storage Tanks.''
    Editorial changes and clarifications. ``Tank'' becomes 
``container.'' We revised the introduction to the definition to remove 
the phrase ``that has been closed'' because the definition would have 
been circular with that language. Instead the introduction references 
the events which must have occurred in order for a container to meet 
the definition.
Person
    Background. The definition of ``person'' proposed in 1991 was 
substantively unchanged from the current rule.
    Comments. We received one comment which urged that we should make 
clear that the United States is bound by every provision of these 
rules.
    Response to comments. See the discussion above (at Sec. 112.1(c)) 
for the applicability of the rule to Federal agencies and facilities.
Production Facility
    Background. The definition of ``production facility'' replaces two 
definitions in the proposed rule, i.e., Oil drilling, production, or 
workover facilities (offshore), proposed Sec. 112.2(j), and Oil 
production facilities (onshore), proposed Sec. 112.2(k). We replaced 
the two proposed definitions with the revised definition for editorial 
brevity as the proposed definitions contained many identical elements. 
This editorial effort effects no substantive changes in the 
requirements for the particular types of production facilities. Each 
facility must follow the requirements applicable to that facility, 
which is generally based on its operations, for example, a workover 
facility.
    Comments. Flowlines and gathering lines. Several commenters 
suggested that flowlines and gathering lines should be deleted from the 
definition because they believed that the installation of structures 
and equipment to prevent discharged oil from reaching navigable waters 
is not practicable for flowlines and gathering lines.
    Wells and separators. Other commenters also argued for the 
exemption of wells and separators.
    DOT definition. Another commenter urged consistency between the 
proposed EPA definition and the DOT definition found at 49 CFR 195.2.
    Single oil or gas field, single operator. One commenter asserted 
that the inclusion of the phrases ``in a single oil or gas field'' and 
``operated by a single operator'' in the definition is confounding. The 
commenter urged that the producing segment of the industry needs to be 
able to combine facilities into one SPCC Plan with an identification of 
the wells to which that Plan applies. The commenter questioned whether 
the inclusion of the word ``single'' would preclude an operator's 
ability to do so.
    Natural gas. Another commenter asked for clarification that natural 
gas processing facilities are not subject to rules for oil facilities.
    Response to comments. Flowlines and gathering lines. Wells and 
separators. EPA disagrees that flowlines and gathering lines, as well 
as wells and separators, should be excluded from the definition. These 
structures or equipment are integral parts of production facilities and 
should therefore be included in the definition. We also disagree with 
the argument that because the installation of structures and equipment 
to prevent discharges around gathering lines and flowlines may not be 
practicable, EPA will be flooded with contingency plans. First of all, 
secondary containment may be practicable. In Sec. 112.7(c), we list 
sorbent materials, drainage systems, and other equipment as possible 
forms of secondary containment systems. We realize that in many cases, 
secondary containment may not be practicable. If secondary containment 
is not practicable, you must provide in your SPCC Plan a contingency 
plan following the provisions of part 109, and otherwise comply with 
Sec. 112.7(d). We have deleted the proposed 1993 provision that would 
have required you to provide contingency plans as a matter of course to 
the Regional Administrator. Therefore, you will rarely have to submit a 
contingency plan to EPA. The contingency plan you do provide in your 
SPCC Plan when secondary containment is not practicable for flowlines 
and gathering lines should rely on strong maintenance, corrosion 
protection, testing, recordkeeping, and inspection procedures to 
prevent and quickly detect discharges from such lines. It should also 
provide for the quick availability of response equipment.
    DOT definition. We changed the proposed definition to be more 
consistent with the DOT definition, found at 49 CFR 195.2, in response 
to a commenter who urged consistency in EPA and DOT definitions. We 
added the uses of the piping and equipment detailed in DOT rule to our 
proposal, for example, ``production, extraction, recovery, lifting, 
stabilization, separation, or treating'' of oil. The terms ``separation 
equipment,'' used in the proposed definition of ``oil production 
facilities (onshore)'', and ``workover equipment,'' used in the 
proposed definition of ``oil drilling, production, or workover 
facilities (offshore)'', were combined into a generic ``equipment.'' 
However, we also modified the proposed definition to reflect EPA 
jurisdiction. We added the word ``structure,'' which was not in the DOT 
definition, to cover necessary parts of a production facility. We also 
added examples of types of piping, structures, and equipment. These 
examples are not an exclusive list of the possible piping, structures, 
or equipment covered under the definition. The new definition 
encompasses all those facilities that would have been covered under 
both former proposed definitions. As we proposed in 1991, and as in the 
current rule, we have retained geographic and ownership limitations.
    Single oil or gas field, single operator. ``A single geographical 
oil or gas field'' may consist of one or more natural formations 
containing oil. The determination of its boundaries is area-specific. 
Such formation may underlie one or many facilities, regardless of 
whether any natural or man-made physical geographical barriers on the 
surface intervene such as a mountain range, river, or road. We disagree 
that the term ``a single operator'' is confusing. An ``owner'' or 
``operator'' is defined in Sec. 112.2 as any ``person owning or 
operating an onshore facility or an offshore facility, and in the case 
of any abandoned offshore facility, the person who owned or operated or 
maintained such facility immediately prior to abandonment.'' A 
``person'' is not restricted to a single natural person. ``Person'' is 
a defined term in the rule (at Sec. 112.2) which includes an 
individual, firm, corporation, association, or partnership.
    Nothing in the definition would preclude an owner or operator from 
combining elements of a production facility into one SPCC Plan with an 
identification of the wells to which that Plan applies.

    Natural gas. Because natural gas is not oil, natural gas facilities 
that do not store or use oil are not covered by this rule. However, you 
should note, that drip or condensate from natural gas production is an 
oil. The storage of such drip or condensate must be included in the 
calculation of oil stored or used at the facility.
    Editorial changes and clarifications. One commenter suggested that 
the definitions proposed were ambiguous because of the use of the words 
``may include.'' We have eliminated the potential ambiguity caused by 
the words ``may include'' by revising the definition with the words 
``Production facility means.''
Regional Administrator
    Background. In 1991, we proposed a definition of ``Regional 
Administrator'' that was substantively unchanged from the current rule. 
In the final rule, we have deleted language concerning the ``designee'' 
of the EPA Regional Administrator because the language is unnecessary. 
Since the Regional Administrator has authority to delegate most 
functions, the term ``designee'' is almost always implied. When he does 
not have authority to delegate a function, the term ``designee'' is 
likewise unnecessary. We received no substantive comments.
Repair
    Background. In 1993, we proposed a definition of ``repair'' in 
conjunction with the proposed rule for brittle fracture evaluation.
    Comments. Ordinary maintenance. Two commenters asked for 
clarification of the term ``repair,'' so that it would exclude ordinary 
day-to-day maintenance activities which are conducted to maintain the 
functional integrity of the tank. Another asked that the infinitive 
``to maintain'' be deleted from the definition of repair so that 
evaluation for brittle fracture would not be required after ordinary, 
day-to-day maintenance.
    Related equipment. Another commenter suggested that we conform the 
proposed definition of ``repair'' with the API 653 definition, 
specifically deleting the phase ``or related equipment.''
    Response to comments. Ordinary maintenance. Some repairs in the 
nature of ordinary maintenance that do not weaken the integrity of the 
container might not necessitate brittle fracture evaluation. ``Repair'' 
means any work necessary to maintain or restore a container or related 
equipment to a condition suitable for safe operation. Typical examples 
of a repair that would trigger a brittle fracture evaluation include 
the removal and replacement of material (such as roof, shell, or bottom 
material, including weld metal) to maintain tank integrity; the re-
leveling or jacking of a tank shell, bottom, or roof; the addition of 
reinforcing plates to existing shell penetrations; and the repair of 
flaws, such as tears or gouges, by grinding or gouging followed by 
welding. The definition of ``repair'' also includes reconstruction. 
Reconstruction means the work necessary to reassemble a container that 
has been dismantled and relocated to a new site. We have amended the 
definition to reflect that ordinary, day-to-day maintenance that does 
not weaken the integrity of the container will not trigger the brittle 
fracture evaluation requirement.
    Related equipment. We agree with the commenter and will not include 
the term ``or related equipment'' in the definition to conform with API 
Standard 653, which does not include repairs of related equipment as a 
criterion for a brittle fracture evaluation.
    Industry standards. Industry standards that may be helpful in 
understanding the definition of repair (and reconstruction) include API 
Standard 653, ``Tank Inspection, Repair, Alteration, and 
Reconstruction.''
    Editorial changes and clarifications. ``Tank'' becomes 
``container.''
Spill Event
    Background. In 1991, we proposed to modify the definition of 
``spill event'' to correspond to the changes described in the 
applicability section of this rule (i.e., Sec. 112.1(b)) relating to 
the expanded scope of CWA jurisdiction.
    Comments. One commenter opposed the definition without explaining 
why. Several commenters argued that the definition should apply only to 
discharges to navigable waters.
    Response to comments. We have withdrawn the proposed definition of 
``spill event,'' and have also deleted the term from the rule. We take 
this action because the term is not mentioned in the CWA and is 
unnecessary. The term is unnecessary because the word ``discharge'' is 
adequate. ``Discharge'' is the term used in the CWA. A discharge as 
described in Sec. 112.1(b) is the same as a spill event. As to the 
comment on EPA jurisdiction, we disagree that our jurisdiction should 
apply only to discharges to navigable waters because the CWA 
establishes our jurisdiction beyond navigable waters (see the 
discussion under Sec. 112.1(b)), and we have the responsibility to 
protect the environment within the scope of our statutory jurisdiction.
Spill Prevention, Control, and Countermeasure Plan, SPCC Plan or Plan
    Background. In 1997, we reproposed the definition of ``SPCC Plan'' 
and withdrew the 1991 proposal. The 1997 proposal would broaden the 
acceptable formats of SPCC Plans, eliminating the requirement that the 
Plan meet the format or sequence formerly specified in the rule.
    Comments. Editorial changes and clarifications. One commenter 
suggested that the last two sentences in the proposed definition should 
be deleted because they contain substantive requirements, and relocated 
to Sec. 112.7. Another commenter thought that the SPCC definition 
should be revised to say that the Plan documents spill prevention 
measures and not compliance with the rule, because compliance is 
determined by comparing the contents of the Plan with the rules.
    Response Plan. A few commenters opposed the definition on the 
theory that it constitutes a type of response plan. Those commenters 
argued that the thrust of the definition should be on spill 
containment, not paperwork.
    Acceptable formats. Many commenters favored the proposal. Several 
suggested various formats that might qualify such as Integrated 
Contingency Plans, State Plans, Electrical Equipment Area Response 
Plans, Stormwater Pollution Prevention Plans, and others. One commenter 
thought that EPA should specify acceptable formats. Several commenters 
suggested that various formats such as Integrated Contingency Plans and 
State Plans are presumptively acceptable.
    Response to comments. Response Plan. We disagree that the proposed 
definition constitutes a ``response plan.'' The definition results in 
no substantive changes in response planning requirements.
    Acceptable formats. We agree that any equivalent prevention plan 
acceptable to the Regional Administrator qualifies as an SPCC Plan as 
long as it meets all Federal requirements (including certification by a 
Professional Engineer), and is cross-referenced from the requirement in 
part 112 to the page of the equivalent plan. We do not agree that we 
should specify acceptable formats. We will give examples of those 
acceptable formats, but those examples are not meant to be exhaustive.
    Examples of an ``equivalent prevention plan'' might be, for 
instance, an Integrated Contingency Plan (ICP), a State plan, a Best 
Management Practice Plan (which is a component of the Stormwater 
Pollution Prevention Plan),

[[Page 47080]]

or other plan that meets all the requirements of part 112 and is 
supplemented by a cross-reference section identifying the location of 
elements in part 112 to the equivalent requirement in the other plan. 
We repeat EPA's commitment to the ICP format, and encourage owners or 
operators to use it. If the equivalent prevention plan has no 
requirement that a Professional Engineer certify it, it will be 
necessary to secure proper certification from the Professional Engineer 
to comply with the SPCC rule.
    An equivalent Plan might be a Plan following the SPCC sequence in 
effect before this final rule became effective. If you choose to use 
the sequence of the rule currently in effect, you may do so, but you 
must cross-reference the requirements in the revised rule to the 
sequence used in your Plan. We have provided a table in section IV.A of 
today's preamble to help you cross-reference the requirements more 
easily. If the only change you make is the addition of cross-
referencing, you need not have a Professional Engineer certify that 
change.
    Another example of an equivalent plan might include a multi-
facility plan for operating equipment. This type of plan is intended 
for electrical utility transmission systems, electrical cable systems, 
and similar facilities which might aggregate equipment located in 
diverse areas into one plan. Examples of operating equipment containing 
oil include electrical equipment such as substations, transformers, 
capacitors, buried cable equipment, and oil circuit breakers.
    A general, multi-facility plan for operational equipment used in 
various manufacturing processes containing over the threshold amount of 
oil might also be acceptable as an SPCC Plan. Examples of operating 
equipment used in manufacturing that contains oil include small lube 
oil systems, fat traps, hydraulic power presses, hydraulic pumps, 
injection molding machines, auto boosters, certain metalworking 
machinery and associated fluid transfer systems, and oil based heaters. 
Whenever you add or remove operating equipment in your Plan that 
materially affects the potential for a discharge as described in 
Sec. 112.1(b), you must amend your Plan. 40 CFR 112.5(a).
    Multi-facility plans would include all elements required for 
individual plans. Site-specific information would be required for all 
equipment included in each plan. However, the site-specific information 
might be maintained in a separate location, such as a central office, 
or an electronic data base, as long as such information was immediately 
accessible to responders and inspectors. If you keep the information in 
an electronic data base, you must also keep a paper or other backup 
that is immediately accessible for emergency response purposes, or for 
EPA inspectors, in case the computer is not functioning. Where you 
place that site-specific information would be a question of allowable 
formatting, as is the question of what is an ``equivalent'' plan; an 
issue subject to RA discretion.
    Still another example of an equivalent plan might be a Best 
Management Practice Plan (BMP) plan prepared under an NPDES permit, if 
the plan provides protections equivalent to SPCC Plans. Not all BMP 
plans will qualify, as some BMP plans might not provide equivalent 
protection. NPDES permits without BMP plans would not qualify.
    BMP plans are additional conditions which may supplement effluent 
limitations in NPDES permits. Under section 402(a)(1) of the CWA, BMP 
plans may be imposed when the Administrator determines that such 
conditions are necessary to carry out the provisions of the Act. See 40 
CFR 122.44(k). CWA section 304(e) authorizes EPA to promulgate BMP 
plans as effluent limitations guidelines. NPDES rules provide for BMP 
plans when: authorized under section 304(e) of the CWA for the control 
of toxic pollutants and hazardous substances; numeric limitations are 
infeasible; or, the practices are reasonably necessary to achieve 
effluent limitations and standards to carry out the purposes of the 
CWA.
    Any format that contains all the required elements of an SPCC Plan 
and provides equivalent environmental protection would be presumptively 
acceptable. The final decision on what is an ``equivalent'' plan, 
however, would be at the discretion of the Regional Administrator. 
``Equivalence'' would not mean that an alternate format would be the 
mirror image of an SPCC Plan, but it would have to contain all the 
required elements of an SPCC Plan. Required elements include, but are 
not limited to, provisions for a written plan, secondary containment or 
a contingency plan following 40 CFR part 109, equivalent inspections 
and tests, security, personnel training, and certification of the plan 
by a Professional Engineer. Acceptance of an equivalent plan does not, 
however, imply any type of approval or submission process. As before, 
SPCC Plans are generally not submitted to the Regional Administrator. 
The Regional Administrator could accept an equivalent prevention plan 
if it: (1) meets all regulatory requirements in the SPCC rule; and (2) 
is supplemented by a cross-reference section identifying requirements 
listed in part 112 to the equivalent requirements in the other 
prevention plan. Partial use of other equivalent prevention plans is 
also acceptable, if the plan is supplemented by elements that meet the 
remainder of the EPA requirements contained in part 112.
    Written Plans. We agree that a ``written'' Plan might also include 
texts, graphs, charts, maps, photos, and tables, on whatever media, 
including floppy disk, CD, hard drive, and tape storage, that allows 
the document to be easily accessed, comprehended, distributed, viewed, 
updated, and printed. Whatever medium you use, however, must be readily 
accessible to response personnel in an emergency. If it is produced in 
a medium that is not readily accessible in an emergency, it must be 
also available in a medium that is. For example, a Plan might be 
electronically produced, but computers fail and may not be operable in 
an emergency. For an electronic Plan or Plan produced in some other 
medium, therefore, a backup copy must be readily available on paper. At 
least one version of the Plan should be written in English so that it 
will be readily understood by an EPA inspector.
    Editorial changes and clarifications. The word ``guidelines'' was 
replaced with ``requirements,'' as proposed in 1991. EPA agrees with 
the relocation of the last two sentences of the definition. Therefore, 
we have transferred those sentences to the introduction of Sec. 112.7, 
in order to maintain the principle that definitions should not contain 
substantive requirements. We have also changed the last sentence which 
was proposed as ``* * * provide adequate countermeasures to an oil 
spill'' to read ``* * * provide adequate countermeasures to a 
discharge.'' We agree that the Plan does not document compliance, but 
merely spill prevention measures and have deleted the sentence noting 
that the Plan documents compliance with the rules. Compliance is 
determined by comparing the contents of the Plan with the regulations.
Storage capacity
    Background. In 1991, we proposed a definition of ``storage 
capacity'' to clarify that it includes the total capacity of a 
container capable of storing oil or oil mixtures. We explained that 
because the percentage of oil in a mixture is determined by the 
operator and can be changed at will, the total capacity of a container 
is considered in determining applicability under this part, regardless 
of whether the container is filled with

[[Page 47081]]

oil or a mixture of oil and another substance, as long as a discharge 
from such container could violate the harmful quantity standards in 40 
CFR part 110.
    Comments. In general. One commenter strongly favored the proposal.
    Standard of measurement. One commenter asserted that volume was the 
proper measure of storage capacity, not total capacity. Another 
commenter suggested a ``working capacity'' standard. Other commenters 
argued that the definition should apply only to containers meeting the 
definition of a bulk storage tank, and that only the oil storage 
capacity of the container be considered. Similarly, a commenter 
asserted that the ``design capacity'' of a container is what should 
count as storage capacity because electrical equipment or other 
interior components might reduce the volume of oil capable of being 
stored.
    Exclusions--small containers; waste treatment facilities, secondary 
containment containers. Small containers. Most commenters were opposed 
to the proposed definition because they either wanted an exclusion for 
small containers or because they wanted an exclusion for containers 
containing de minimis amounts of oil. These commenters argued that 
small containers would not present a significant threat of discharge.
    Waste treatment facilities. The rationale of commenters supporting 
an exemption for waste treatment containers was that some containers 
had non-usable space at the top of the container; also some containers 
contain only trace amounts of oil. Therefore, for example, storage 
tanks used to store or treat wastewaters are likely to have to be 
considered when determining storage capacity since many wastewaters 
have incidental oil content prior to treatment. They also argued that 
the definition would subject publicly owned treatment works (POTWs) to 
the rule because tanks used to control stormwater surges might contain 
small amounts of oil from runoff from parking lots and city streets.
    Secondary containment containers. Some commenters argued that the 
definition would apply to tanks used to provide secondary containment 
when determining the storage capacity of a facility.
    Response to comments. Standard of measurement. In most instances 
the shell capacity of a container will define its storage capacity. The 
shell capacity (or nominal or gross capacity) is the amount of oil that 
a container is designed to hold. If a certain portion of a container is 
incapable of storing oil because of its integral design, for example 
electrical equipment or other interior component might take up space, 
then the shell capacity of the container is reduced to the volume the 
container might hold. When the integral design of a container has been 
altered by actions such as drilling a hole in the side of the container 
so that it cannot hold oil above that point, shell capacity remains the 
measure of storage capacity because such alteration can be altered 
again at will to restore the former storage capacity. When the 
alteration is an action such as the installation of a double bottom or 
new floor to the container, the integral design of the container has 
changed, and may result in a reduction in shell capacity. We disagree 
that operating volume should be the measurement, because the operating 
volume of a tank can be changed at will to below its shell capacity.
    The keys to the definition are the availability of the container 
for drilling, producing, gathering, storing, processing, refining, 
transferring, distributing, using, or consuming oil, and whether it is 
available for one of those uses or whether it is permanently closed. 
Containers available for one of the above described uses count towards 
storage capacity, those not used for these activities do not. Types of 
containers counted as storage capacity would include some flow-through 
separators, tanks used for ``emergency'' storage, transformers, and 
other oil-filled equipment.
    Exclusions--small containers; waste treatment facilities. Small 
containers. This definition is applicable to both large and small 
storage and use capacity. Owners or operators of small facilities above 
the regulatory threshold are subject to the rule, and need to know how 
to calculate their storage or use capacity.
    However, in the applicability section of the rule, we have excluded 
containers of less than 55 gallons from the scope of the SPCC rule, 
addressing the comments of those commenters who argued for a minimum 
container size. See Sec. 112.1(d)(5). A container above that size that 
is available for use or storage containing even small volumes of oil 
must be counted in storage capacity.
    Waste treatment facilities. We agree with the commenter that a 
facility or part thereof (except at an oil production, oil recovery, or 
oil recycling facility) used exclusively for wastewater treatment 
system and not to meet any part 112 requirement should not be 
considered storage capacity because wastewater treatment is neither use 
nor storage of oil. Therefore, we have exempted such facilities or 
parts thereof from the rule. However, note that certain parts of such 
facilities may continue to be subject to the rule. See the discussion 
under Sec. 112.1(d)(6).
    Secondary containment containers. Containers which are used for 
secondary containment and not storage or use, are not counted as 
storage capacity.
    Editorial changes and clarifications. We use the word ``container'' 
instead of ``tank or container,'' because a tank is a type of 
container. We have clarified the definition to provide that the storage 
capacity of a container is the volume of oil that the container could 
hold, and have therefore substituted the words ``shell capacity'' of 
the container for ``total capacity.'' This is merely a clarification, 
and not a substantive change. We also deleted the words ``for purposes 
of determining applicability of this part,'' because the words were 
unnecessary. We also deleted the last phrase of the proposed 
definition, ``whether the tank or container is filled with oil or a 
mixture of oil and other substances,'' because the contents of the 
container do not affect the definition of its shell capacity.
Transportation-related and non-transportation-related
    Background. In 1991, we reproposed the current definition of 
``transportation-related and non-transportation-related.'' We received 
no comments on the proposal. Therefore, we have promulgated the 
definition as proposed.
United States
    Background. In 1991, we proposed to revise the definition of 
``United States'' to conform to the definition enacted in the 1978 
amendments to the CWA. We received no comments on this proposal. 
Therefore, we have promulgated the definition as proposed.
Vessel
    Background. In 1991, we reproposed the current definition of 
vessel. We received no comments on this proposal. Therefore, we have 
promulgated the definition as proposed. We note that a barge or other 
watercraft that has been determined by the Coast Guard to be 
permanently moored to the shore, and used for storage, is no longer 
being used as a vessel, and does not fit within the definition of 
vessel. Rather, it becomes a bulk storage container counted as storage 
capacity. The same concept is found in the rules for mobile facilities 
at Sec. 112.3(c), which provides that SPCC Plans apply to mobile 
facilities only

[[Page 47082]]

``while the facility is in a fixed (non-transportation) operating 
mode.''
Wetlands
    Background. In 1991, we proposed a definition of ``wetlands'' to 
define the term as used in the definition of ``navigable waters.'' The 
definition of wetlands conforms to the definition in 40 CFR part 110 
relating to the discharge of oil.
    Comments. Several commenters opposed the definition because they 
believe that it includes a series of examples which may or may not be 
correct. They also alleged that the definition fails to implement the 
1987 U.S. Army Corps of Engineers Wetlands Manual or the documents 
implementing that Manual. Another commenter asked for EPA clarification 
of what is a wetland, given the ``vague and arguable notion of a 
wetland.''
    Response to comments. The examples listed in the definition are 
intended to help the reader with guidelines to identify wetlands. While 
the examples generally represent types of wetlands, they are not 
intended to be a categorical listing of such wetlands. There may be 
examples listed that under some circumstances do not constitute 
wetlands. We believe that the 1987 Wetlands Manual is a useful source 
material for wetlands guidance. It would be impossible to specify in a 
rule every type of situation where wetlands occur. The examples listed 
in the definition are not exclusive, but provide help in clarifying 
what may be a wetland.

Section 112.3 Introduction

    Background. We have added an introduction to Sec. 112.3 as an 
editorial device to simplify the language in the paragraphs of this 
section.

Section 112.3(a)--Time Line for Preparation and Implementation of Plans 
for Existing Facilities

    Background. In 1991, we proposed to require owners or operators of 
onshore and offshore facilities in operation 60 days after the 
effective date of this final rule to ``maintain a prepared and fully 
implemented facility SPCC Plan. . . . '' We proposed giving these 
owners or operators 60 days from the date the final rule was published 
to revise their existing Plans and implement the revisions. The 
proposed rule also reflected the expanded geographic scope of the rule 
provided by CWA amendments.
    Comments. Time period to prepare and implement a Plan. A number of 
commenters favored the proposal. Many more favored a ``phase-in'' 
period, or a longer period within which to comply. Commenters suggested 
compliance periods ranging from 60 days to 7 years. Many commenters 
clustered around the suggestion that a 6 month phase-in period be 
allowed. Many others suggested compliance by the next three-year 
review, as required by Sec. 112.5(b) at that time.
    Extensions. Several commenters asked that extensions of time to 
prepare and implement Plans be automatic if Plans must be in effect 
prior to the commencement of operations. Another suggested that 
extension requests be considered ``routine.''
    Acquired facilities. One commenter asked how we would treat 
acquired facilities, whether as new or continuing operation facilities.
    Start of operations. One commenter asked when operations start, 
stating that is not always a clearly defined time. The commenter 
suggested that instead of requiring a prepared and implemented Plan, we 
should allow that a response team be in place.
    Small facilities. One commenter asserted that the time line for 
Plan preparation and implementation was unreasonable for small 
facilities, and asked that facilities with under 10,000-gallon capacity 
be allowed to operate while developing and implementing a Plan.
    Response to comments. Time period to prepare and implement a Plan. 
We have been persuaded by commenters that a longer phase-in period than 
60 days is required for facilities currently in operation or about to 
become operational within one year after the effective date of this 
rule.
    Facilities currently in operation. For a facility in operation on 
the effective date of this rule, we changed the dates in the proposed 
rule for preparation and implementation of plans from 60 days to a 
maximum of one year to accord with the time frames in the current rule. 
The owner or operator of a facility in operation on the effective date 
of this rule will have 6 months to amend his Plan and must fully 
implement any amendment as soon as possible, but within one year of the 
effective date of the rule at the latest. The owner or operator of a 
facility which has had a discharge as described in Sec. 112.1(b), or 
reasonably could be expected to have one, already has an obligation to 
prepare and implement a Plan.
    For example, an owner or operator whose facility became operational 
four years before the effective date of this rule is the owner or 
operator of a facility currently in operation on the effective date of 
this rule. He is therefore subject to current Sec. 112.3(b), and should 
have prepared his Plan no later than three and one half years before 
the effective date of this rule, and fully implemented it no later than 
three years before the effective date of this rule. Assuming that he 
still has not prepared a Plan on the effective date of the rule, he 
must prepare and fully implement a Plan immediately that meets the 
requirements of the revised rule. He is subject to penalties for 
violation of current Sec. 112.3(b) until he does so, and the penalties 
would accrue from the time the original deadlines passed before the 
effective date of this rule. The owner or operator of a facility which 
became operational four years before the effective date of the rule, 
and who prepared and fully implemented his Plan in compliance with 
current Sec. 112.3(b), must amend his Plan within 6 months of the 
effective date of this rule to meet the requirements of the revised 
rule, and fully implement the amended Plan as soon as possible, but no 
later than one year after the effective date of the rule.
    An owner or operator whose facility became operational 7 months 
before the effective date of the rule is an owner or operator of a 
facility currently in operation and is therefore subject to current 
Sec. 112.3(b). He should have prepared his Plan one month before the 
effective date of this rule. If he did, he will have 6 months from the 
effective date of this rule to amend that Plan to meet the requirements 
of the revised rule, and must fully implement the amended Plan as soon 
as possible, but within one year of the effective date of this rule. If 
he has not prepared a Plan by the effective date of the current rule as 
required, then he must prepare and fully implement a Plan immediately 
that meets the requirements of the revised rule. He is subject to 
penalties for violation of current Sec. 112.3(b) until he does so.
    An owner or operator whose facility became operational 4 months 
before the effective date of this rule is also an owner or operator of 
a facility currently in operation on the effective date of this rule 
and therefore subject to the current rule. However, in this case, the 
6-month deadline to prepare a Plan under the current Sec. 112.3(b) has 
not yet passed. Therefore, the owner or operator is subject to the Plan 
preparation and implementation deadlines in Sec. 112.3(a) of the 
revised rule. He now has 6 months from the effective date of this rule 
to prepare a Plan that meets the requirements of this rule. If he had 
already prepared a Plan under current Sec. 112.3(b), he has 6 months 
from the effective date of this rule to amend that Plan. In either 
case, he must fully implement the Plan (or amended Plan)

[[Page 47083]]

as soon as possible after the 6-month Plan preparation deadline of this 
rule, but no later than one year after the effective date of this rule.
    The owner or operator of a facility in operation on the effective 
date of this rule who is required to have prepared or implemented an 
SPCC Plan, but has not, remains subject to penalties for violation of 
current SPCC regulations. Such owner or operator is consequently 
subject to civil penalties for a violation of current Sec. 112.3 if the 
time has expired for preparation or implementation of his Plan.
    Facilities becoming operational within one year after the effective 
date of the rule August 13, 2003. If you begin operations after the 
effective date of the rule through one year after the effective date of 
this rule August 16, 2002, you will have until one year from the 
effective date of this rule to prepare and implement your Plan. In 
other words, if the rule becomes effective on January 1, and you begin 
operations on January 2, you must prepare and implement your Plan by 
January 1 of the following year. If you begin operations on June 30, 
you still have until January 1 of the following year to prepare and 
implement your plan. If you begin operations on December 31, you still 
have until January 1 (the next day) of the following year to prepare 
and implement your Plan. The rationale for the time frame in the rule 
is that you will have had notice of the Plan preparation and 
implementation requirements from the publication date of the rule, a 
period of 30 days plus one year. In addition, you would already have 
had notice of the general requirement for preparation of an SPCC Plan 
from the current part 112 regulations. Therefore, the owner or operator 
of a facility planning to become operational within one year after the 
effective date of this rule should start working on his Plan in time to 
have it fully implemented within the year.
    New facilities. The owner or operator of a facility that becomes 
operational more than one year after the effective date of this rule 
must prepare and implement a Plan before beginning operations.
    A year phase-in period is in line with legitimate business and 
investment expectations. It allows a reasonable period of time for 
facilities to undertake necessary constructions, purchases of 
equipment, or to effect changes of procedures. And again, the general 
requirement for preparation of a Plan already exists in part 112, so 
new facilities should already have been aware of the need for a Plan.
    Extensions. While we have extended the time period for compliance, 
we understand that some facilities may still need extensions of time to 
comply. Extensions may be necessary to secure necessary manpower or 
equipment, or to construct necessary structures. If you are an owner or 
operator and an extension is necessary, you may seek one under 
Sec. 112.3(f). If no Plan amendments are necessary after you review 
today's rule, you must maintain your current Plan and cross-reference 
its elements to the redesignated requirements.
    Acquired facilities. For SPCC purposes, we consider acquired 
facilities as facilities that are already operating rather than new 
facilities because these facilities must already have SPCC Plans if 
they exceed applicable thresholds.
    Start of operations. Start of operations is when you begin to store 
or use oil at a facility. Often this may be a testing or calibration 
period prior to start up of normal operations. With the extended time 
line we have provided, no response team is required, but such a team 
may be a good engineering practice. At a minimum, you must prepare and 
implement a Plan as required by this rule.
    Small facilities. With the extended time line we have provided, all 
facilities, large or small, have adequate notice and time in which to 
prepare and implement a Plan.
    Editorial changes and clarifications. We deleted the first sentence 
of the proposed rule from the final rule because it is unnecessary. It 
is unnecessary because the obligation to have prepared a Plan is 
incurred under current section Sec. 112.3(b) for the owner or operator 
of a facility in operation before the effective date of this rule. For 
the owner or operator of a facility that becomes operational on or 
after the effective date of this rule, revised Sec. 112.3 provides the 
time period within which he must prepare and implement a Plan. The 
deleted sentence read, ``Owners or operators of onshore facilities that 
become operational after September 16, 2002, and could be reasonably be 
expected to discharge oil as described in Sec. 112.1(b)(1) of this 
part, shall prepare a facility SPCC Plan in accordance with Sec. 112.7, 
and in accordance with any of the following sections that apply to the 
facility: Secs. 112.8, 112.9, 112.10, and 112.11.''

Section 112.3(b)--Time Line for Preparation and Implementation of Plans 
for New Facilities

    Background. In 1991, we proposed that new facilities contemplating 
the start of operations be required to prepare and fully implement 
Plans before beginning operations. Our rationale was that our 
experience showed that many types of failures occur during or shortly 
following facility startup and virtually all prevention, containment, 
and countermeasure practices are a part of the facility design or 
construction.
    Comments. Many commenters suggested various phase-in periods, as 
discussed above.
    Response to comments. We believe that our original rationale is 
still correct. Experience with the implementation of this regulation 
shows that many types of failures occur during or shortly following 
startup and that virtually all prevention, containment, and 
countermeasure practices are part of the facility design or 
construction. Therefore, it can be beneficial to the environment and 
carries out the intent of the statute if a facility Plan is prepared 
and implemented before startup. However, to provide sufficient notice 
to new facilities that a Plan must be prepared and implemented before 
beginning operations, we have delayed implementation of this section 
until one year after the effective date this rule. If you begin 
operations within one year of the effective date of this rule, you must 
comply with the requirements in Sec. 112.3(a). However, if you begin 
operations more than one year after the effective date of this rule, 
your facility would be ``new'' and you would have to prepare and 
implement an SPCC Plan before you begin operations. If you need an 
extension to comply, you may seek one under Sec. 112.3(f).
    Editorial changes and clarifications. The phrase ``* * * could 
reasonably be expected to discharge oil, as described in Sec. 112.1(b) 
of this part* * *'' becomes ``could reasonably be expected to have a 
discharge as described in Sec. 112.1(b).''

Section 112.3(c)--Time Line for Preparation and Implementation of Plans 
for Mobile Facilities

    Background. In 1991, we proposed that owners or operators of 
onshore and offshore mobile facilities be required to have a prepared 
and implemented Plan before beginning operations. Since existing mobile 
facilities are a subset of existing facilities, we generally assume 
that these facilities already have a Plan in place, as the rule now 
requires. 40 CFR 112.3(c). Both new and existing mobile facilities 
would therefore have to comply with the rule requiring a fully prepared 
and implemented Plan before beginning operations.
    Comments. In general. One commenter believed that requiring Plans

[[Page 47084]]

for mobile facilities is unworkable because their physical surroundings 
are subject to change. Another commenter supported our proposal to 
allow general Plans for mobile facilities.
    Multi-well drilling programs. One commenter asked if Plan updates 
would be required in a field where a multi-well drilling program is 
underway. The commenter suggested that updates should be required only 
after the drilling program is complete.
    Response to comments. In general. We agree that the physical 
surroundings of mobile facilities are subject to change. However, we 
disagree that changing physical surroundings should exempt mobile 
facilities from the rule. Mobile facilities may have ``general'' Plans 
and need not prepare a new Plan each time the facility is moved to a 
new site. When a mobile facility is moved, it must be located and 
installed using the spill prevention practices outlined in the Plan for 
the facility.
    Mobile facilities currently in operation are assumed to have 
implemented Plans already, because they are currently legally required 
to do so. Both new and existing mobile facilities must have Plans 
prepared and fully implemented before operations may begin. If after 
your review of today's rule, you decide that no amendment to your Plan 
is necessary, except for cross-referencing, you may continue to operate 
under your existing Plan, but you must promptly cross-reference the 
provisions in the Plan to the new format. Extension requests under 
Sec. 112.3(f) are also available for mobile facilities under the proper 
conditions.
    Multi-well drilling programs. It is not necessary to amend the Plan 
every time you drill a well in a field containing multiple wells. A 
general Plan will suffice.
    Editorial changes and clarifications. We deleted the phrase ``using 
good engineering practice,'' in the third sentence of the paragraph 
because good engineering practice is required of all Plans. See the 
introduction to Sec. 112.7. Therefore, the phrase was unnecessary.

Section 112.3(d)--Certification by Professional Engineers

    Background. The current rule only requires that the Professional 
Engineer (PE), having examined the facility and being familiar with the 
provisions of part 112, attest by means of his certification that the 
Plan has been prepared in accordance with good engineering practices. 
In 1991, we proposed to add specificity to the meaning of the 
certification requirements for a PE. We proposed that the PE attest 
that he is familiar with the requirements of part 112, that he has 
visited the facility, that the Plan has been prepared in accordance 
with good engineering practice and the requirements of part 112, that 
required testing has been completed, and that the Plan is adequate for 
the facility.
    Comments. Certification requirement. Most commenters supported a 
certification requirement for PEs. Some opposed it on grounds that if 
all the components of the Plan were specified by rule, then 
certification is unnecessary. One U.S. territory, U.S. Samoa, noted 
that it doesn't register PEs, arguably making compliance with the rule 
difficult for owners or operators of facilities in Samoa.
    Other commenters thought a PE certification requirement was 
unnecessarily burdensome and costly for small facilities, but did not 
provide cost estimates. One commenter asserted that PE certification 
should not be required for small facilities, due mainly to the 
prohibitive cost. The commenter also maintained that most small 
facilities have tanks that are required by State or local law to have 
the Underwriters Laboratory Seal of Approval and to have submitted a 
detailed plan for review and approval to the fire marshal prior to 
installation.
    Certification by other environmental professionals. Several 
commenters suggested that certification could be effected by another 
environmental professional, rather than a PE, or by another 
environmental professional with PE oversight.
    Good engineering practice. One commenter noted that EPA specified 
in the 1991 preamble that the application of good engineering practice 
will require that appropriate provisions of applicable codes, 
standards, and regulations be incorporated into the SPCC Plan for a 
particular facility. 56 FR 54617-18. The commenter added, however, that 
we do not define ``good engineering practice'' for this program, and 
urged EPA to specify in more detail as to its understanding of the 
term.
    Testing. Some commenters wrote that it would be better for the PE 
to enumerate all the inspections and tests that have been completed, 
plus those that should be completed before the facility commences 
operations and those that should be undertaken periodically after it 
commences operations. A few commenters objected to the proposed 
requirement that the PE attest that required testing has been 
completed, suggesting instead that the operator is responsible for 
completion of testing. Another commenter suggested that the PE be 
allowed to attest to the presence of those written procedures which 
require testing.
    Non-technical changes. Most supported the idea that non-technical 
changes to a Plan (for example, the emergency contact list, phone 
numbers, or names) need not have PE certification.
    Time limit for PE certification. One commenter suggested a time 
limit of three years or less on PE certification, suggesting that the 
PE should be required to reinspect the premises periodically, 
preferably annually, to ascertain that the Plan continues to be 
implemented.
    PE costs. Some commenters argued that requiring an independent or 
outside PE for Plan certification would be extremely expensive for 
facilities located in remote areas. These commenters were principally 
concerned that we did not fully account for the cost to a facility 
owner or operator for a PE to visit each facility before certifying a 
Plan. Requiring the use of an independent or outside PE could be 
burdensome to facility owners or operators.
    Response to Comments. Certification requirement. PE certification 
of all facilities, both large and small, is necessary because a 
discharge as described in Sec. 112.1(b) from any size facility may be 
harmful, and PE review and certification of a Plan may help prevent 
that discharge. We disagree that PE certification is prohibitively 
costly for small facilities. A Plan certified by a PE may well save the 
owner or operator money due to improved facility operations and 
decreased likelihood of discharge, thus averting potentially costly 
cleanups. Because a Plan for a smaller facility is likely to be less 
complicated than a Plan for a larger facility, PE certification costs 
should likewise be lower for a smaller facility. In our Information 
Collection Request, estimated total costs for a new facility to prepare 
and begin implementation of a Plan, including PE certification costs, 
are $2,201 for a small facility, $2,164 for a medium facility, and 
$2,540 for a large facility. This cost is incurred only in the year 
that the facility first becomes subject to the rule. This one-time cost 
incurred by a small facility is less than 1.5 percent of the average 
annual revenue for small facilities in all industry categories. The 
cost for the PE certification alone would represent even less than 
that. As shown in Chapter 5 of the Economic Analysis for this 
rulemaking, the average annual revenue for the smallest regulated 
facilities (under the current rule) ranges from $150,000 to $6,833,000, 
depending on the industry category. For example,

[[Page 47085]]

farms with annual revenue between $100,000 and $249,999 have an average 
annual revenue per farm of $161,430, and $2,201 (the one-time cost to 
prepare and implement a Plan) represents only 1.36 percent of that 
annual revenue. Of course, under the revised rule many of these small 
facilities will not be regulated by the SPCC program at all.
    A PE's certification of a Plan means that the PE is certifying that 
the facility's equipment, design, construction, and maintenance 
procedures used to implement the Plan are in accordance with good 
engineering practices. And this is important because good engineering 
practices are likely to prevent discharges. PE certification, to be 
effective for SPCC purposes, must be completed in accordance with the 
law of the State in which the PE is working. For example, some States 
require a PE to apply his seal to effectuate a certification. Others do 
not.
    We also disagree that small facilities need not have PE 
certification for SPCC Plans when the tanks are certified by the 
Underwriters Laboratory. A Plan consists of more than a certified tank. 
It contains provisions for secondary containment, integrity testing, 
and other measures to prevent discharges. Those provisions require PE 
certification to ensure that they meet the requirements of the rule and 
that the Plan is effective to prevent discharges.
    Finally, by modifying the applicability provision in 
Sec. 112.1(d)(2), we are today exempting many small facilities from the 
requirement to prepare and implement a Plan at all, thus saving all 
prospective PE costs.
    In response to the commenter from Samoa, who noted that territory 
does not register PEs, the rule would allow an SPCC facility there to 
hire a PE licensed in some other State or U.S. territory.
    Certification by other environmental professionals. Certification 
by a PE, rather than by another environmental professional is necessary 
to ensure the application of good engineering judgment. A PE must 
obtain a Bachelor of Engineering degree from an accredited engineering 
program, pass two comprehensive national examinations, and demonstrate 
an acceptable level (usually four additional years) of engineering 
experience. A licensed engineer is also required to practice 
engineering solely within his areas of competence and to protect the 
public health, safety, and welfare. All licensed PEs, no matter who 
their employer, are required by State laws and codes of ethics to 
discharge their engineering responsibilities accurately and honestly. 
Furthermore, State governments have and do exercise the authority to 
discipline licensed PEs who fail to comply with State laws and 
requirements. Other environmental professionals may not have similar 
expertise nor be held to similar standards as the licensed PE.
    It is not always necessary for a PE to visit the facility. 
Therefore, we have revised Sec. 112.3(d) to a allow site visit by 
either the PE or his agent. Often it will be sufficient if the PE 
reviews the work of other engineering professionals who have visited 
the facility. Someone would have to visit the facility, but not 
necessarily the PE. Nevertheless, in all cases the PE must ensure that 
his certification represents an exercise of good engineering judgment. 
If that requires a personal site visit, the PE must visit the facility 
himself before certifying the Plan.
    Good engineering practice. As we noted in the 1991 preamble (at 56 
FR 54617-18), good engineering practice ``will require that appropriate 
provisions of applicable codes, standards, and regulations be 
incorporated into the SPCC Plan for a particular facility.'' We agree 
with the commenter that the rule needs more specificity in this regard. 
Therefore, we have amended Sec. 112.3(d)(1)(iii) to specifically 
include consideration of applicable industry standards as an element of 
the PE's attestation that the Plan has been prepared in accordance with 
good engineering practice. We reiterate today, as we did in 1991, that 
consideration of applicable industry standards is an essential element 
of good engineering practice. Industry standards include industry 
regulations, standards, codes, specifications, recommendations, 
recommended practices, publications, bulletins, and other materials. 
(See Sec. 112.7(a)(1) and (j).) The owner or operator must specifically 
document any industry standard used in a Plan to comply with this 
section. The documentation should include the name of the industry 
standard, and the year or edition of that standard. However, as 
discussed above, we have chosen not to incorporate specific industry 
standards into the rule.
    Testing. The proposed rule would have required the PE to certify 
that required testing was completed. We have been persuaded by comments 
that the requirement should be that procedures for inspections and 
tests have been established, not necessarily completed, because the PE 
is not normally present at time of completion. Nor do we believe it is 
necessary to impose a requirement that the PE oversee all testing 
because the PE only shares responsibility with the owner or operator 
for establishing procedures, not for their implementation, which is the 
sole responsibility of the owner or operator. However, the PE may 
include in the Plan a schedule for testing, with specific time frames 
for the completion of that testing. See also the discussion in today's 
preamble (at section IV.D.3) on ``Completion of Testing.''
    Non-technical changes. PE certification is not required for items 
that do not require engineering judgment, such as telephone numbers; 
names on lists; some, but not all, product changes (see the response to 
comments of Sec. 112.5(a)); ownership changes; or, any other changes 
not requiring engineering judgment.
    Time limit for PE certification. We disagree that there should be a 
time limit on PE certification because the rule ensures that the PE 
reviews the Plan at appropriate times. Thus, current PE certifications 
remain valid. But new certifications after the effective date of this 
rule must include the required attestations. If you are an owner or 
operator you must review your Plan at least every five years (under 
revisions made in today's rule), and amend it if new technology is 
warranted. Also, you must amend your Plan to conform with any 
applicable rule requirements, or at any time you make any change in 
facility design, construction, operation, or maintenance that 
materially affects its potential for a discharge as described in 
Sec. 112.1(b). All material amendments require PE certification. 
Therefore, because a Plan will likely require one or more amendments 
requiring PE review and certification, a time limit on PE 
certifications is unnecessary. See Sec. 112.5(c).
    Other PE issues. As to other PE issues, as noted above (see section 
IV.D.2 of this preamble), the PE need not be independent of the 
facility. Nor is there a requirement that he not have a financial 
interest in it. We believe the professional integrity of a PE and the 
professional oversight of boards licensing PEs are sufficient to 
prevent any abuses.
    It is not necessary that the PE be licensed in the same State as 
the facility because the SPCC program is national in scope and 
therefore State expertise is unnecessary. While States may prescribe 
more stringent requirements than EPA, a PE may familiarize himself with 
any particular requirements a State may impose and address them in the 
Plan. See Sec. 112.7(j). Furthermore, violations of PE ethics may be 
handled by the licensing board of the PE's state no matter where the 
work is done.
    EPA maintains that a site visit is necessary, but the visit may be 
by either the PE or his agent, so long as a visit by

[[Page 47086]]

an agent is consistent with good engineering practice. A visit by the 
PE's agent can generally be sufficient given that the PE will oversee 
and be responsible for his agent's work.
    PE costs. We note that we did not propose a requirement for an 
independent PE, but requested comments on it. In the final rule, we 
require either the PE or the PE's agent to visit and examine the 
facility before the PE certifies the Plan. An agent might include an 
engineering technician, technologist, graduate engineer, or other 
qualified person to prepare preliminary reports, studies, and 
evaluations after visiting the site. The PE, after reviewing the 
agent's work, could then legitimately certify the Plan. Also, in the 
final rule, we allow the PE to be an employee of the facility as well 
as registered in a different State than the facility is located, in 
order to approve a Plan. The rationale is that SPCC work is national in 
scope and therefore State expertise is unnecessary.
    Editorial changes and clarifications. ``Registered Professional 
Engineer'' becomes ``licensed Professional Engineer.'' The first 
sentence of the paragraph was proposed as, ``No SPCC Plan shall be 
effective to satisfy the requirements of this part unless it has been 
reviewed by a Registered Professional Engineer.'' We revised it to 
read, ``A licensed Professional Engineer must review and certify a Plan 
for it to be effective to satisfy the requirements of this part.'' This 
revision is due to the fact that PEs are licensed by States.

Section 112.3(e)--Location and Availability of Plan

    Background. In 1991, we proposed that the Plan be available at the 
facility if the facility is normally manned at least four hours a day, 
in lieu of the current requirement that the Plan be available if the 
facility is manned eight hours a day. If the facility is not attended 
at least four hours a day, the Plan would have to be available at the 
nearest field office.
    The rationale for the change is that some facilities interpreted 
the eight hour requirement not to apply to a facility that is only 
operating seven and one-half hours per day, with a half an hour 
deducted for lunch. The availability of a Plan can be extremely useful 
in preventing and mitigating discharges, therefore it must be available 
most of the time at attended facilities.
    Comments. Editorial changes and clarifications. Several commenters 
questioned the meaning of ``normal working hours,'' asking whose hours 
that meant, those of EPA or those of the facility. Several commenters 
questioned the meaning of ``nearest field office.''
    Plan availability. Several commenters favored the proposal. One 
commenter suggested that we amend the rule to provide that the Plan be 
available ``without advance notice,'' so that it would be fully 
implemented at all times, not just when an inspection is impending. One 
commenter thought that the Plan should always be located at the 
facility, whether manned or not, perhaps protected by a laminated 
cover, and at ``appropriate control centers.''
    State and local agencies. Another commenter suggested that the Plan 
be filed with the local fire department and LEPC (Local Emergency 
Planning Committee) to facilitate public review. One State suggested 
there be a Federal requirement that the Plan also be filed with the 
State.
    Response to comments. Nearest field office, normal working hours. 
The term ``nearest field office'' in paragraph (e)(1) means the office 
with operational responsibility for the facility, or the emergency 
response center for the facility, because those locations ensure 
accessibility for personnel who need to respond in case of a discharge. 
The term ``normal working hours'' in paragraph (e)(2) refers to the 
working hours of the facility or the field office, not EPA.
    Plan availability. Today we have finalized the 1991 proposal that 
the Plan must be available at the facility if it is normally attended 
at least four hours per day, or at the nearest field office if it is 
not so attended. A Plan must always be available without advance 
notice, because an inspection might not be scheduled. You are not 
required to locate a Plan at an unattended facility because of the 
difficulty that might ensue when emergency personnel try to find the 
Plan. However, you may keep a Plan at an unattended facility. If you do 
not locate the Plan at the facility, you must locate it at the nearest 
field office.
    State and local agencies. You are not required to file or locate a 
Plan with a State Emergency Response Commission or Local Emergency 
Planning Committee or other State or local agency because the 
distribution would unjustifiably increase the information collection 
burden of the rule, and not all committees or agencies may want copies 
of SPCC Plans. Should a State wish to require filing of a Federal SPCC 
Plan with a State or local committee or agency, it may do so. No 
Federal requirement is necessary.
    Editorial changes and clarifications. In paragraph (e)(2), we 
deleted the term ``or authorized representative'' after ``Regional 
Administrator,'' because the Regional Administrator may delegate his 
duties. Therefore, the term is unnecessary.

Section 112.3(f)--Extension of Time

    Background. In 1991, we proposed to allow only new facilities to 
apply for extensions of time to comply with the requirements of part 
112. The current rule allows any facility to apply for an extension, 
including existing fixed and mobile facilities. The rationale for 
limiting extension requests to new facilities was that existing fixed 
and mobile facilities have had since 1974 to comply with the rule.
    Comments. Automatic extensions. Several commenters suggested that 
we automatically grant extension requests if we are to require a Plan 
to be in effect prior to commencement of operations.
    Existing Plan requirements. Another commenter criticized the 
proposed requirement to submit the existing Plan with each extension 
request, because EPA's review of the Plan cannot practically be an 
element of the extension granting process. Another commenter suggested 
that the language in paragraph (f)(3) would be better if it said that 
the existing Plan's provisions remain in effect until they are 
superseded by changes proposed by the facility, because these words 
better reflect the intention of the rule.
    Amendments. Several commenters urged EPA to allow extensions for 
preparation and implementation of Plan amendments.
    Response to comments. Automatic extensions. Automatic extension 
requests are not justifiable because we have extended the time within 
which most facilities have to prepare and implement Plans. See 
Sec. 112.3(a), (b), and (c). Also, under the revised rule, you may 
request an extension for the preparation and implementation of any 
Plan, or amendment to any Plan. See Sec. 112.3(f).
    Existing Plan requirements. We have broadened the scope of 
extension requests to any facility that can justify the request, 
because for every type of facility there may be cases in which an 
extension can be justified. Existing fixed and mobile facilities may 
experience delays in construction or equipment delivery or may lack 
qualified personnel, and these circumstances may be beyond the control 
of, and without the fault of, the owner or operator. We also agree with 
the commenter that the submission of the entire Plan as a matter of 
course is unnecessary to evaluate each extension request. Therefore, we 
have amended the rule to provide that the Regional Administrator may 
request your Plan if he deems it appropriate. But we do not believe 
that he will

[[Page 47087]]

always do so. It may be necessary under some circumstances. The 
Regional Administrator also retains discretion to request the Plan 
after on-site review, or after certain discharges. See Sec. 112.4(a)(9) 
and (d). We disagree with the commenter's proposed rewrite of the owner 
or operator's obligations while the request is pending because the 
better policy is to require compliance with the rest of the rule that 
is not affected by the extension request, rather than saying that the 
existing Plan continues in effect.
    Amendments. We have also added a provision for an extension of time 
to prepare and implement an amendment to the Plan, as well as an entire 
Plan. We believe that there may be cases in which an extension can be 
justified for a Plan amendment because the same extenuating 
circumstances may apply.
    Editorial changes and clarifications. In paragraph (f)(3), ``letter 
of request'' becomes ``written extension request.'' In the last 
sentence of that paragraph, ``with respect to'' becomes ``related to.''

Section 112.4(a)--Reporting Certain Discharges to EPA

    Background. In 1991, we proposed to require more information than 
is currently required in the rule for reporting certain discharges. If 
your facility discharged more than 1,000 gallons in a discharge as 
described in Sec. 112.1(b), or discharged oil in quantities that may be 
harmful in more than two discharges as described in Sec. 112.1(b) 
within any consecutive twelve month period, you would have been 
required to submit certain information to the Regional Administrator.
    In 1993, we proposed a modification to Sec. 112.4(d)(1) which would 
allow the Regional Administrator to require the submission of the 
listed information in Sec. 112.4(a)(1) at any time, whether or not 
there had been a discharge as described in Sec. 112.1(b).
    In 1997, we proposed a reduction of the amount of information 
currently required by Sec. 112.4(a). We proposed to eliminate the 
following information, unless the Regional Administrator specifically 
requested it: (1) The date and year of initial facility operation; (2) 
maximum storage or handling capacity of the facility and normal daily 
throughput; and, (3) a complete copy of the SPCC Plan with any 
amendments.
    Comments. In general. Most commenters favored the 1997 proposal. 
Several commenters opposed the proposal.
    Information submission at any time. One commenter argued that the 
1993 proposal allowing EPA to require submission of the information 
required in Sec. 112.4(a)(1) and to require Plan amendments at any time 
is vague and does not provide adequate notice to the regulated 
community.
    Submission of entire Plan. One commenter thought that meaningful 
review of the information submitted was impossible without the entire 
Plan. Two commenters believed that EPA would always request the 
information it proposed to eliminate.
    Discharge threshold. Other commenters proposed a higher threshold 
for having to report a discharge than is currently required by 
Sec. 112.4(a). Those thresholds ranged from 25-55 gallons. One 
commenter suggested that we relax the reporting requirement for very 
minor releases of petroleum products. Another suggested that if the 
discharge causes a sheen that dissipates within 24 hours, there should 
be no obligation to report.
    Maps, flow diagrams, and charts. Several commenters suggested that 
we eliminate the requirement to submit maps, flow diagrams, and charts 
because those documents ``add nothing useful to the inquiry.''
    Off-site category. Another commenter suggested that we create an 
``off-site'' category of spill reports for discharges reported by a 
facility that are in a water body adjacent to the reporter's facility, 
or for discharges that originate off-site, but migrate to the facility.
    Calculation of time for discharge reports required by 
Sec. 112.4(a). Several commenters suggested that we calculate the time 
for the submission of discharge reports required by Sec. 112.4(a) on a 
``block'' basis, rather than a ``rolling'' basis.

Response to Comments

    Information submission at any time. We agree with the commenter 
that the 1993 proposal to give the Regional Administrator authority to 
require submission of the requested information in this section at any 
time is vague, and have therefore withdrawn that part of the proposal. 
We will only require such information after the discharges specified in 
this section.
    Submission of entire Plan. CWA section 311(m) provides EPA with the 
authority to require an owner or operator of a facility subject to 
section 311 to make reports and provide information to carry out the 
objectives of section 311; and CWA section 308(a) provides us with 
authority to require the owner or operator of any ``point source'' to 
make such reports as the Administrator may reasonably require. 
Therefore, we disagree that submission of the entire Plan is always 
necessary when reporting discharges under Sec. 112.4(a). We believe the 
information now required to be submitted is adequate to assess the 
cause of discharge and the ability of the facility to prevent future 
discharges. If the RA believes that the entire Plan has utility, he can 
request it. However, we disagree that RAs will always require 
submission of the Plan, or other information not required, as a matter 
of course. RAs may use their administrative discretion not to require 
the submission of Plan information or other additional information.
    Discharge threshold. 42 gallons. We agree that a higher threshold 
of reporting discharges is justifiable because we believe that only 
larger discharges should trigger an EPA obligation to review a 
facility's prevention efforts. We also agree that a higher threshold 
should trigger a facility's obligation to submit information and 
possibly have to take further prevention measures. Therefore, we have 
changed the threshold for reporting after two discharges as described 
in Sec. 112.1(b). Under the revised rule, if you are the owner or 
operator of a facility subject to this part, you must only submit the 
required information when in any twelve month period there have been 
two discharges as described in Sec. 112.1(b), in each of which more 
than 42 U.S. gallons, or one barrel, has been discharged. We adopted 
the 42 gallon threshold on a commenter's suggestion. We believe that a 
42 gallon threshold is the appropriate one to trigger a facility's 
information and possibly to have to take further prevention measures. 
When multiple discharges occur at a facility subject to the SPCC 
program, such as a generating station, they often involve the discharge 
of very small amounts of oil, and these discharges tend to come 
randomly from a lube pipe, an oil level sight glass crack, or some 
other apparatus, and do not normally indicate a recurring problem with 
the container. Having two or more of these small discharges does not 
indicate that the facility's SPCC Plan requires revision. The other 
reporting threshold of 1,000 gallons in any a single discharge as 
described in Sec. 112.1(b) remains the same.
    We disagree that a sheen caused by a discharge as described in 
Sec. 112.1(b) over the threshold amount that disappears within 24 hours 
should not require submission of information. The discharge itself may 
indicate a serious problem at the facility which needs to be corrected. 
The discharge report may give us the information necessary to require 
specific correction measures.

[[Page 47088]]

    ``Sheen'' rule. The duty imposed by the CWA to report to the 
National Response Center all discharges that may be harmful, further 
described by 40 CFR 110.3, is unchanged. Those discharges include 
discharges that violate applicable water quality standards; or, cause a 
film or sheen upon or discoloration of the surface of the water or 
adjoining shorelines or cause a sludge or emulsion to be deposited 
beneath the surface of the water or upon adjoining shorelines.
    Maps, flow diagrams, and charts. In response to comments which 
questioned the usefulness of such information, we have modified the 
provision regarding maps, flow diagrams, topographical maps (now 
required by paragraph (a)(6) of the current rule) to clarify that only 
the information necessary to adequately describe the facility and 
discharge, such as maps, flow diagrams, or topographical maps is 
necessary--not necessarily all of the information listed in the 
paragraph. To effect this change, we added the words ``as necessary'' 
after ``topographical maps.'' ``As necessary'' means as determined by 
the owner or operator, subject to the obligations of this rule, unless 
the RA requests more information. There might be circumstances in which 
the owner or operator would submit only a brief description of the 
facility or a map, for example, because flow diagrams and topographical 
maps were unnecessary to describe the discharge, and would not help the 
RA to determine whether any amendment to the Plan was necessary to 
prevent future discharges as described in Sec. 112.1(b).
    Off-site category. There is no necessity for an ``off-site'' 
category of discharges as described in Sec. 112.1(b) because only a 
discharge as described in Sec. 112.1(b) that originates in a facility 
subject to this part counts for purposes of Sec. 112.4(a).
    Calculation of time for discharge reports required by 
Sec. 112.4(a). We believe a ``rolling'' basis is the appropriate method 
to calculate a discharge as described in Sec. 112.1(b) for purposes of 
the rule because discharges as described in Sec. 112.1(b) that are 
closer in time are more likely to be related in cause. Discharges that 
are more proximate in time may indicate a problem that needs to be 
remedied. A ``rolling basis'' means that each discharge as described in 
Sec. 112.1(b) triggers the start of a new twelve month period. For 
example, if discharge #1 occurred on January 1, and if 
discharge #2 occurred on June 2, discharge #2 would 
trigger the regulatory submission and would start a new twelve month 
period. If discharge #3 occurred on the following February 3, 
it would again trigger a submission, because discharge #3 would 
be within 12 months of discharge #2. While the ``rolling 
basis'' would trigger more regulatory submissions than the ``block 
basis,'' we believe that it would enhance environmental protection 
because it would call potential problems to the attention of the 
Regional Administrator sooner, and allow them to be remedied sooner by 
a Plan amendment where necessary.
    ``Block'' basis. The other approach would be to use a ``block'' 
period. Under this type of calculation, each third discharge as 
described in Sec. 112.1(b) would not trigger a submission if it 
occurred within 12 months of discharge #2, but it would start 
the beginning of a new 12 month period. For example, if discharge 
#1 occurred on January 1, and discharge #2 on June 2, 
discharge #2 would trigger a submission. Discharge #3 
on the following February 3 would not trigger a submission, but would 
start a new 12 month period. The principal justification for block 
reporting is also that discharges more closely related in time are more 
likely to be related. Our concern with this method is that if the 
February 3 discharge (i.e., discharge #3) is within twelve 
months of discharge #2, this situation could indicate that 
there is a problem that has not been remedied, so the February 3 
discharge should trigger a reporting submission.
    Maximum storage or handling capacity. In 1997, we proposed deletion 
of current paragraph (5) (renumbered as paragraph (4) in today's final 
rule), concerning the maximum storage or handling capacity of the 
facility and normal daily throughput. We have reconsidered this 
proposal and decided to withdraw it because the referenced information 
is necessary information. We have therefore retained the language in 
the rule. Storage capacity and normal daily throughput are important 
indicators of the impact of a potential discharge as described in 
Sec. 112.1(b).
    Additional information. If the Regional Administrator requires 
other information, for example, concerning the spill pathway, or any 
response measures taken, this request is authorized under renumbered 
Sec. 112.4(a)(9), current Sec. 112.4(a)(11).
    Adjoining shorelines, natural resources, affected natural 
resources. Discharges into navigable waters are not the only discharges 
reportable for purposes of this section. We note that any discharge as 
described in Sec. 112.1(b) is also within the scope of this section's 
reportable discharges.
    Editorial changes and clarifications. If a particular information 
request is inapplicable, you may omit it, but must explain why it is 
inapplicable. Several plural nouns like ``names'' and ``causes'' become 
singular. Wherever the phrase ``and/or'' appears, we have revised the 
phrase to read ``and.'' In 1997's proposed Sec. 112.4(a)(6), 
redesignated as Sec. 112.4(a)(7), ``spill'' becomes ``discharge as 
described in Sec. 112.1(b).'' In 1997's proposed Sec. 112.4(a)(8), 
redesignated as Sec. 112.4(a)(9), ``spill event'' becomes 
``discharge.''

Section 112.4(b)--Applicability of Sec. 112.4

    Background. Under current Sec. 112.4(b), the Sec. 112.4 
requirements for spill reporting do not apply until the expiration of 
the time permitted for the preparation and implementation of a Plan 
pursuant to Sec. 112.3(a), (b), (c), and (f). In 1991, we proposed that 
Sec. 112.4 would not apply until the expiration of the time permitted 
for the preparation and implementation of a Plan under Sec. 112.3(f) 
only. Section 112.3(f) is the time period in which you are permitted to 
prepare and implement a Plan under an extension request.
    We proposed to delete the references to Sec. 112.3(a), (b) and (c) 
because the current time periods allowed in these paragraphs for the 
preparation and implementation of the Plan (before commencement of 
operation for new facilities or mobile facilities, or after the 
effective date of the rule for other existing facilities) were proposed 
for deletion. Because future facilities would generally have a Plan 
prepared and implemented before beginning operations, there was no 
longer a need to temporarily relieve facilities of spill reporting 
obligations under Sec. 112.4(a), unless the Regional Administrator 
granted an extension under Sec. 112.3(f) to prepare and implement a 
Plan. We received no comments on this proposal.
    In today's rule, however, we have revised Sec. 112.3 to extend the 
time lines for certain facilities to prepare and implement Plans. To 
accord with this change, we are maintaining the approach under current 
Sec. 112.4(b) to provide that the Sec. 112.4 spill reporting 
requirements will not apply until the expiration of the time permitted 
for the initial preparation and implementation of a Plan under 
Sec. 112.3(a), (b), (c), and (f). Today, we have also revised 
Sec. 112.3(a) to provide an extended time line for preparing a Plan 
amendment and Sec. 112.3(f) to provide for an extension request for an 
amendment to a Plan. Therefore, we have also revised Sec. 112.4(b) to 
provide that the obligation to submit information as required by

[[Page 47089]]

Sec. 112.4(a) does not arise until the expiration of the time permitted 
for the initial preparation and implementation of the Plan under 
Sec. 112.3, but not for any amendments to the Plan. We did not 
previously propose to relieve facilities of Sec. 112.4 reporting 
requirements during Plan amendments or extensions for Plan amendments. 
An amendment may or may not be directly related to the cause of the 
discharge as described in Sec. 112.1(b), and therefore may have little 
relevance to the duty to submit discharge reports to EPA.

Section 112.4(c)--Supplying Discharge Information to the States

    Background. In 1991, we proposed that you must provide the same 
discharge information that you submit to the Regional Administrator 
under Sec. 112.4(a) to the State agency in charge of oil pollution 
control activities. The current rules require that you provide that 
information to the State agency in charge of water pollution control 
activities.
    Comments. Legal authority. One commenter suggested that we have no 
legal authority for the proposal. Another commenter asserted that EPA 
could only implement State agency recommendations if those 
recommendations fell within the scope of the SPCC rule.
    In general. Several commenters suggested the proposal was redundant 
and unnecessary, because only EPA regulates the SPCC program, not the 
States.
    State agency review. One commenter, a State, favored the proposal 
and noted that more than one State agency has statutory jurisdiction 
over oil pollution control in that State. That State and another 
suggested that all relevant State agencies receive the information. One 
commenter suggested that EPA should identify the appropriate State 
agency to which notice is due. One commenter thought the proposed 
change was misleading. Another commenter, a State, suggested that EPA 
provide the States money to review the submitted discharge information.
    Response to comments. Legal authority. We have ample legal 
authority to finalize this rule. A similar rule has been in effect 
since 1974. Section 311(j)(1) of the CWA authorizes the Federal 
government (and EPA through delegation) to establish ``procedures, 
methods, and equipment and other requirements for equipment to prevent 
discharges of oil. * * *'' Section 112.4(c) of this rule is a procedure 
to help prevent discharges that fall within the scope of that statutory 
provision. It enables States to learn of discharges reported to EPA and 
to make recommendations as to further procedures, methods, equipment, 
and other requirements that might prevent such discharges at the 
reporting facility.
    We can only implement State agency suggestions that are within the 
scope of our authority under section 311 of the CWA.
    In general. The commenter is correct that the SPCC program is a 
Federal program, but we believe that in working with the States, we can 
improve the Federal program through coordination with State oil 
pollution prevention programs. Therefore, we believe that the 
information provided to States is neither redundant nor unnecessary. 
Nor is the section misleading; it clearly states the obligation of the 
owner or operator.
    State agency review. We modified the 1991 proposal on the 
commenters' suggestion to include notice to any appropriate State 
agency in charge of oil pollution control activities, since there may 
be more than one such agency in some States and all may have need for 
the information. We do not list such agencies in the rule, as a 
commenter suggested, because the names and jurisdiction of the State 
agencies are subject to change. It is the reporter's obligation to 
learn which State agencies receive the discharge reports. Most States 
publish documents on an ongoing basis, similar to the Federal Register, 
which publicize relevant regulatory information.
    We do not provide State agencies funds to review these discharge 
reports due to budgetary constraints. While we assume that many States 
review these reports carefully, we cannot require them to do so. Thus, 
this action is not an unfunded mandate from the Federal government to 
the States. But if States do review the reports, they do so at their 
own expense.
    Editorial changes and clarifications. In the last sentence of the 
paragraph, ``discharges of oil'' becomes ``discharges.''

Section 112.4(d)--Amendment of Plans Required by the Regional 
Administrator

    Background. In 1991, we proposed that after review of materials 
under 112.4(a), the Regional Administrator (RA) might require amendment 
of the SPCC Plan. We also proposed that the RA might require Plan 
amendment after reviewing contingency plan materials submitted for 
approval. See proposed Sec. 112.7(d), 1991.
    In 1993, we proposed that the RA would also have authority to 
require Plan amendment after on-site review of the Plan. In addition, 
we proposed a clause empowering the RA to approve the Plan or require 
amendment.
    We also proposed in 1993 allowing the RA to require submission of 
the information listed in Sec. 112.4(a) at any time. The rationale to 
get this information was to prevent discharges from happening, in 
addition to seeking to correct the conditions that may have caused the 
discharge. See the background and response to comments under 
Sec. 112.4(a) for a discussion of this proposal.
    Comments. Regional Administrator approval of Plans. Several 
commenters criticized the idea of RA approval of the Plan on the theory 
that it is an unwarranted intrusion into the manner in which operators 
do business. Another urged an appeal process if EPA approval of Plans 
is required.
    Plan information and amendments. One commenter argued that allowing 
EPA to require submission of the information required in Sec. 112.4(a) 
at any time and to require Plan amendments at any time is vague and 
does not provide adequate notice to the regulated community. Several 
commenters were concerned that EPA would inconsistently require overly 
stringent measures in some Plans or might require amendments unrelated 
to discharge potential or which were financially unreasonable. Two 
commenters urged a time limit on EPA decision making following 
submission of required information. Another commenter was concerned 
that no provision required PE certification of amendments required by 
EPA.
    Response to comments. Regional Administrator approval of Plans. We 
have deleted the provision that would have allowed RA approval of 
Plans. We have decided not to create a new class of SPCC Plans which 
require EPA approval, either Plans submitted following certain 
discharges as required by Sec. 112.4(a) or Plans with contingency 
plans, because we do not believe such approval is necessary in order to 
ensure effective Plans.
    Plan information and amendments. We agree that allowing EPA to 
require submission of the information required in Sec. 112.4(a) at any 
time, and thereafter to require Plan amendments, is vague, and 
therefore we have withdrawn that part of the proposal. Furthermore, it 
is unnecessary because sections 308 and 311(m) of the CWA already 
provides us with adequate authority to request necessary Plan 
information.
    While the RA will not have authority under this section to approve 
Plans, he has authority to require Plan amendment. We will strive to be 
as timely as possible in reviewing the

[[Page 47090]]

information when submitted, and making decisions on any required 
amendments. A time limit on the RA's decision making authority would be 
unnecessary because a facility may continue to operate under its 
existing Plan while the RA's decision is pending. While we will 
consider cost in our decision making, amendments may be required on a 
case-specific basis to help prevent discharges. Any technical amendment 
required would require PE certification. See Sec. 112.5(c) .
    Editorial changes and clarifications. We have deleted reference to 
the RA's approval of the submitted Plan in proposed paragraph (d)(2), 
because the RA will not have authority to approve a Plan. He does, 
however, have authority to require Plan amendment under today's 
revision of Sec. 112.4(d).

Section 112.4(e)--Notification and Implementation of Required 
Amendments

    Background. In 1991, we reproposed the current notification 
provision concerning required Plan amendments, and the time lines for 
implementation of those amendments.
    Comments. Who receives notice. One commenter wanted EPA to notify 
railroads directly, instead of their registered agents, because of the 
time lag that might occur between the time the agent received notice 
and the owner or operator of the facility received notice. Another 
commenter urged that we also provide notice to the facility operator, 
the facility improvement owner, and the facility landowner. His 
rationale for such expanded notice was that a major problem may be 
addressed by the operator or EPA, without the knowledge and/or consent 
of the facility improvements owner and the facility landowner.
    Appeals procedure. One commenter suggested that we include a 
reference to the appeal procedure for amendments in this section.
    Response to comments. Who receives notice. In reply to the railroad 
commenter, the rule requires notice only to the owner or operator of 
the facility, and the registered agent, if any and if known. Notice 
from EPA to the facility improvements owner and landowner is 
unnecessary because these matters can and should be handled between the 
facility owner or operator and the owner or operator of the 
improvements or the landowner.
    Appeals procedure. We have not included a reference to the appeals 
procedures for required amendments in this section because the appeals 
procedures follow immediately in the next paragraph, making such 
reference redundant.
    Editorial changes and clarifications. We have changed the proposed 
requirement to mail a copy of the notice to the registered agent of a 
corporation to a requirement that such notice be effected only if the 
registered agent is known to EPA. The notification requirement for 
registered agents now tracks the notification requirement for 
registered agents in Sec. 112.1(f). Because we have withdrawn the 
proposed requirement that a corporation submit that agent's name or 
address in the submission of information required by Sec. 112.4(a), 
such agent may not be known to EPA. In the last sentence of the final 
rule, ``amendment of the Plan'' becomes ``amended Plan.''

Section 112.4(f)--Appeals of Required Amendments

    Background. In 1991, we reproposed the current appeals procedures 
for required Plan amendments. We received no substantive comments. 
Therefore, we have promulgated the procedures as proposed.
    Editorial changes and clarifications. We deleted language 
concerning the ``designee'' of the EPA Administrator because it is 
unnecessary. Current delegations allow the Administrator to delegate 
this function.

Section 112.5(a)--Plan Amendment by an Owner or Operator

    Background. In 1991, we proposed to require that an owner or 
operator amend the Plan before making any change in facility design, 
construction, operation, or maintenance materially affecting the 
facility's potential for the discharge of oil into the waters of the 
United States unless the RA granted an extension. We also listed some 
examples of facility changes which would require Plan amendment, noting 
that these examples were not an exclusive list.
    Comments. When amendment is necessary. Several commenters favored 
the proposal. Others provided differing standards for amending Plans. A 
number of commenters suggested that no amendments should be necessary 
when a facility change results in a decrease in the volume stored or a 
decrease in the potential for an oil spill. Another suggested a 
standard that amendments should be made ``when there are indicia of 
problems.'' A commenter suggested a standard that no amendments would 
be required except for those changes which would cause the spill 
potential to exceed the Plan's capabilities because day-to-day changes 
do not affect the worst case spill and the Plan should not have to be 
amended on a day-to-day basis. One commenter suggested that small 
facilities with less than 5,000 gallon-capacity should be exempted from 
the need to amend their Plans for the listed acts. Another commenter 
asserted that instead of being required to amend their Plans before 
changes are made, operators should be encouraged to incorporate new 
procedures into their SPCC Plans to prevent and contain potential 
discharges which might result from performing needed repairs and 
replacements. The rationale for the suggestion was that operators will 
then not ``save up'' potential amendments due to the burden of 
preparing an amendment.
    Material changes. Many commenters offered opinions on the examples 
of material changes listed in the rule for which amendments would be 
required. Some suggested that the rule should read that these are only 
examples of changes that may trigger amendment. Several commenters 
suggested that decommissioning a tank should not trigger an amendment 
because ``as a tank is removed, so is the requirement for an SPCC 
Plan.'' Another commenter noted that changing a product in a tank or 
cleaning a tank should not be considered commissioning or 
decommissioning a tank. One commenter suggested that an amendment to 
the Plan should be required when there is a change of product stored 
within the tank.
    Documenting no change or certain activities. Another commenter 
suggested that a log book might be used instead of a Plan amendment to 
document ``routine activities'' and measures taken to maintain the 
spill prevention and response integrity of the facility. Several 
commenters suggested that an identical replacement of tanks or other 
equipment should not be considered a material change and therefore 
amendment should not be required. A utility commenter asked that 
facilities be allowed to accumulate minor modifications for a period of 
6 months, then update the Plan.
    EPA approval. Another commenter suggested that we clarify that EPA 
approval of an amendment made under this section is not required.
    Time line for amendment implementation. Numerous commenters opposed 
the proposed requirement that a Plan be amended before any material 
changes are made. Commenters suggested various alternative amendment 
time lines ranging from 90 days to six months following such changes, 
with a cluster of commenters around the six months alternative. Others 
suggested that the Plan be
