ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This final rule revises wastewater and drinking water
regulations to include updated versions of test procedures (i.e.,
analytical methods) for the determination of chemical, radiological,
and microbiological pollutants and contaminants in wastewater and
drinking water. The updated versions of analytical methods have been
published by one or more of the following organizations: ASTM
International (ASTM; formerly the American Society for Testing and
Materials), United States Geological Survey (USGS), United States
Department of Energy (DOE), American Public Health Association (APHA),
American Water Works Association (AWWA), and Water Environment
Federation (WEF). Previously approved versions of the methods remain
approved.
DATES: This final rule is effective on November 22, 2002. The
incorporation by reference of the publications listed in today's rule
is approved by the Director of the Federal Register as of November 22,
2002. For judicial review purposes, this final rule is promulgated as
of 1 p.m. (Eastern time) on November 6, 2002 as provided at 40 CFR 23.2
and 23.7.
ADDRESSES: The record for this rulemaking has been established under
docket number W-99-21. Copies of the public comments received, EPA
responses, and all other supporting documents (including references
included in this document) are available for review at the U.S.
Environmental Protection Agency, Water Docket, on Monday through
Friday, excluding Federal holidays, between 9 a.m. and 3:30 p.m.
Eastern Time. Please contact the Water Docket for an appointment. From

SUPPLEMENTARY INFORMATION:
Potentially Regulated Entities
A. Clean Water Act
EPA Regions, as well as States, Territories, and Tribes, are
authorized to implement the National Pollutant Discharge Elimination
System (NPDES) program, issue permits that comply with the technology-
based and water quality-based requirements of the Clean Water Act. In
doing so, the NPDES permitting authorities, including authorized
States, Territories, and Tribes, make a number of discretionary choices
associated with permit writing, including the selection of pollutants
to be measured and, in many cases, limited, in permits. If EPA has
``approved'' (i.e., promulgated through rulemaking) standardized
testing procedures for a given pollutant, the NPDES permit must specify
that analysis of that pollutant be conducted in accordance with one of
the approved testing procedures or an approved alternate test
procedure. Permitting authorities may, at their discretion, require the
use of any method approved at 40 CFR part 136 in the permits they
issue. Therefore, NPDES permits may incorporate the testing procedures
in today's rulemaking so dischargers with NPDES permits could be
affected by the standardization of testing procedures in this
rulemaking. In addition, States, Territories, or authorized Tribes
responsible for providing certification of Federal licenses under Clean
Water Act section 401, could be regulated by today's rulemaking because
these organizations are directed to use the standardized testing
procedures. Categories and entities that may ultimately be regulated
include:
------------------------------------------------------------------------
Examples of potentially regulated
Category entities
------------------------------------------------------------------------
State, Territorial, and Tribal States, Territories, and Tribes
Governments. authorized to administer the NPDES
permitting program; States,
Territories, and Tribes providing
certification under Clean Water Act
section 401.
------------------------------------------------------------------------
B. Safe Drinking Water Act
Public water systems are the regulated entities required to conduct
analyses to measure for contaminants in water samples. However, EPA
Regions, as well as States, and Tribal governments with primacy to
administer the regulatory program for public water systems under the
Safe Drinking Water Act, sometimes conduct analyses to measure for
contaminants in water samples. If EPA has established a maximum
contaminant level (``MCL'') for a given drinking water contaminant, the
Agency also approves (i.e., promulgates through rulemaking)
standardized testing procedures for analysis of the contaminant. Once
EPA standardizes such test procedures, analysis using a standard (or
approved alternate test procedures) is required. Public water systems
required to test water samples must use one of the approved
standardized test procedures. Categories and entities that may
ultimately be regulated include:
------------------------------------------------------------------------
Examples of potentially
Category regulated entities NAICS \a\
------------------------------------------------------------------------
State, Local, and Tribal State, Local, and Tribal 924110

These tables are not intended to be exhaustive, but rather provide
a guide for readers regarding entities likely to be regulated by this
action. The tables list the types of entities that EPA is now aware
could potentially be regulated by this action. Other types of entities
not listed in the tables could also be regulated. To determine whether
your facility or organization is regulated by this action, you should
carefully examine the applicability language at 40 CFR 136.1 (NPDES
permits and CWA) and 40 CFR 141.2 (definition of public water system).

I. Legal Authorities
A. Clean Water Act
This regulation is promulgated under the authority of sections 301,
304(h), 307, and 501(a) of the Clean Water Act (CWA), 33 U.S.C. 1311,
1314(h), 1317, 1361(a) (the ``Act''). Section 301 of the Act prohibits
the discharge of any pollutant into navigable waters unless the
discharge complies with a National Pollutant Discharge Elimination
System (NPDES) permit, issued under section 402 of the Act. Section
304(h) of the Act requires the EPA Administrator to ``promulgate
guidelines establishing test procedures for the analysis of pollutants
that shall include the factors which must be provided in any
certification pursuant to section 401 of this Act or permit
applications pursuant to section 402 of this Act.'' Section 501(a) of
the Act authorizes the Administrator to ``prescribe such regulations as
are necessary to carry out his functions under this Act.'' EPA
publishes CWA analytical method regulations at 40 CFR Part 136. The
Administrator also has made these test procedures applicable to
monitoring and reporting of NPDES permits (40 CFR part 122, Sec. Sec.
122.21, 122.41, 122.44, and 123.25), and to implementation of the
pretreatment standards issued under section 307 of the Act (40 CFR part
403, Sec. Sec. 403.10 and 403.12).
B. Safe Drinking Water Act
The Safe Drinking Water Act (SDWA), as amended in 1996, requires
EPA to promulgate national primary drinking water regulations (NPDWRs)
that specify maximum contaminant levels (MCLs) or treatment techniques
for drinking water contaminants (SDWA section 1412 (42 U.S.C. 300g-1)).
NPDWRs apply to public water systems pursuant to SDWA section
1401(1)(A) (42 U.S.C. 300f(1)(A)). According to SDWA section
1401(1)(D), NPDWRs include ``criteria and procedures to assure a supply
of drinking water which dependably complies with such maximum
contaminant levels; including accepted methods for quality control and
testing procedures * * *'' (42 U.S.C. 300f(1)(D)). In addition, SDWA
section 1445(a) authorizes the Administrator to establish regulations
for monitoring to assist in determining whether persons are acting in
compliance with the requirements of the SDWA (42 U.S.C. 300j-4). EPA's
promulgation of analytical methods is authorized under these sections
of the SDWA as well as the general rulemaking authority in SDWA section
1450(a), (42 U.S.C. 300j-9(a)).
II. Regulatory Background and History
EPA has promulgated analytical methods for all currently regulated
wastewater and drinking water pollutants and contaminants. For most
contaminants, EPA has promulgated regulations approving the use of more
than one standardized analytical method, and regulated entities may use
any one of these approved methods for determining compliance with an
MCL, an NPDES permit or another monitoring requirement. After any
regulation is published, EPA may amend the regulations to approve
additional methods or modifications to existing approved methods, or
withdraw approved methods that become obsolete.
On January 16, 2001, EPA published a direct final rule that was to
approve many updated methods published by non-EPA organizations for use
in wastewater and drinking water compliance monitoring (66 FR 3466-
3497). On the same day, EPA published a companion proposal that
proposed approval of all methods in the direct final rule methods (66
FR 3526-3527). The proposal was to serve as the basis for a final rule
if the direct final was withdrawn due to adverse comments. Because
adverse comments were received from one commenter, EPA withdrew the
direct final rule on May 15, 2001 (66 FR 26795) and deferred final
action in order to respond to those comments. Today's rulemaking
constitutes EPA's final action on the proposed rule.
III. Summary of Final Rule
A. This rule amends the regulations at 40 CFR part 136 to:
(1) Allow the use of 19 updated methods published by the ASTM
International (ASTM; formerly the American Society for Testing and
Materials) in the 1999 Annual Book of ASTM Standards, Vols. 11.01 and
11.02.
(2) Allow the use of 189 updated methods published by the Standard
Methods Committee in Standard Methods for the Examination of Water and
Wastewater, 19th edition, 1995, and 20th edition, 1998.
(3) Allow the use of 22 methods published by the United States
Geological Survey (USGS) in open file reports and method compendiums.
(4) Correct minor editorial errors and update method source
references.
B. This rule amends the regulations at 40 CFR Part 141 to:
(1) Allow the use of 12 updated methods published in the 1999
Annual Book of ASTM Standards, Vols. 11.01 and 11.02.
(2) Allow the use of 62 updated methods published by the Standard
[[Page 65222]]
Methods Committee in Standard Methods for the Examination of Water and
Wastewater, 20th edition, 1998.
(3) Allow the use of six updated methods published by the
Department of Energy (DOE) in the document ``EML Procedures Manual,''
28th Edition, Volume 1, 1997, for determinations of radionuclide
contaminants.
(4) Correct minor editorial errors and update method source
references.
C. This rule amends the regulations at 40 CFR Part 143 to:
(1) Recommend an updated version of a method (D 4327-97) published
in the 1999 Annual Book of ASTM Standards, Vol. 11.01.
(2) Recommend updated versions of 12 methods published by the
Standard
Methods Committee in Standard Methods for the Examination of Water
and Wastewater, 20th edition, 1998.
(3) Correct update method source references.
IV. Changes From the January 16, 2001 Rule Proposal
A. Editorial Corrections
Standard Methods 6220 B, 6230 B, and 6200 C were correctly
specified in the rule text of the January, 16, 2001, direct final rule,
but they were incorrectly referenced in Table 3 (64 FR 3470) of the
preamble to that rule. Corrections to the preamble errors are noted as
follows:
Standard Methods Number Changes (Corrected)
------------------------------------------------------------------------
18th edition 19th edition 20th edition
------------------------------------------------------------------------
6220 B 6220 B 6200 C
6230 B 6230 B 6200 C
------------------------------------------------------------------------
Edits to 40 CFR Part 136
Two errors in the rule section of the January 2001 direct final
rule at 40 CFR part 136.3 are corrected in today's rule as follows:
(1) A portion of a citation originally intended as a placeholder in
footnote 45 to Table IB was inadvertently included. This citation is
corrected to reference the correct USGS document number. ``98-xxx'' is
changed to ``00-170.''
(2) Footnote 44 to Table 1B is renumbered, and a new footnote 44 is
added to conform with a final rule that was published on December 30,
1999 (64 FR 73414). The December 1999 rule renumbered footnote 44 to
footnote 51, and amended footnote 44 to specify information about a
cyanide method that was the subject of the December 1999 rule. The
direct final rule inadvertently overlooked these 1999 amendments.
Edits to 40 CFR Part 141
A commenter noted an error and EPA noted an omission in the
references to methods at 40 CFR part 141.21 for determination of E
coli. in drinking water. The error and omission are addressed, in
today's rule, by revising 40 CFR 141.21 as follows:
(1) Footnote 1 to the table in paragraph (f)(3), paragraphs
(f)(6)(i), (f)(6)(ii) and (f)(8) are revised to clarify instructions
for the determining E coli. A commenter noted that the E coli. methods
in the 19th and 20th editions of Standard Methods describe or reference
procedures differently than the 18th edition version of these methods.
These differences are editorial, not substantive, and all three
versions of these methods provide equivalent results. Today's
correction adds clarifying language to make the equivalency of the
18th, 19th and 20th edition versions of these E coli. methods more
apparent.
(2) Sentence 6 of paragraph (f)(5) is revised to add a citation to
the 20th edition of Standard Methods that was inadvertently omitted in
the January 2001 direct final rule. The Agency's intent in the January
16, 2001 direct final rulemaking was and is to allow use of more recent
editions of Standard Methods, such as the 20th edition.
B. Additional Technical Edits to 40 CFR Part 136.3
A commenter noted several editorial errors in the current 40 CFR
part 136.3 tables. EPA is correcting these errors in today's rule.
Correction of these errors is not a substantive change to EPA
regulations. These are simple editorial corrections that improve the
clarity and accuracy of the regulations.
Edits to Table 1C
(1) A typographical error in the listing of the method for
parameter 3 (acrolein) is corrected. Method ``604'' is changed to
``624.''
(2) An incorrect reference to Method 610 for parameter 4,
acrylonitrile, is removed. Method 610 is not applicable to
determinations of acrylonitrile.
(3) An incorrect reference to Method 6410B for parameter 22, carbon
tetrachloride is removed. Method 6410B is not applicable to
determinations of carbon tetrachloride.
(4) A misspelling of the analyte listing for parameter 27 is
corrected, ``chloraform'' is changed to ``chloroform.'' Also, a missing
number in the note specified in the ``Other'' column was inadvertently
omitted, ``Note, p. 130.'' is changed to ``Note 3, p. 130.''
(5) A missing reference to footnote 5 is added to parameter 82, N-
Nitrosodimethylamine, and removed for parameters 83 and 103, N-
Nitrosodi-n-propylamine, and 2,3,7,8-tetrachlorodibenzo-p-dioxin,
respectively. Footnote 5 expands the analytical scope of Method 625 to
include additional parameters. However, the annotation of these
parameters in Table IC omitted parameter 82, and should not have
included parameters 83 and 103.
(6) A typographical error in the analyte listing for parameter 87
is corrected, 2,2'-oxybis(1-chloropropane) is changed to 2,2'-oxybis(1-
chloropropane). In addition, an alternative analyte name, bis(2-
chloroisopropyl) ether, is added for parameter 87. These changes
conform the CFR listing of parameter 87 with the dual, equivalent name
designation of this parameter in the methods (EPA Methods 611, 625 and
1625B) approved for compliance determinations of parameter 87.
(7) A typographical error in the reference to the compliance method
for parameter 105, tetrachloroethene, is corrected. Method ``6410 B
[18th, 19th]'' is changed to ``6210 B [18th, 19th].'' Method 6410 B is
not applicable to determinations of tetrachloroethene.
(8) An incorrect reference to Method ``1625\5a\'' for parameter 103
(2,3,7,8-tetrachlorodibenzo-p-dioxin) is removed along with the
superfluous footnote 5a to table 1C. Method 1625 is not applicable to
determinations of this parameter.
Edits to Table 1D
A typographical error in the analyte listing for parameter 11 is
corrected. ``[delta]-BHC'' is changed to ``[gamma]-BHC.''
Edits to Tables 1B and 1C
To correctly specify the approved revision of listed EPA methods, a
revision letter is added to the method
[[Page 65223]]
listings for EPA methods in Table 1C. References to EPA methods
``1613,'' ``1624'' and ``1625'' are changed to ``1613B,'' ``1624B'' and
``1625B,'' respectively. In Table IB, EPA Method ``1631'' is changed to
``1631C.''
V. Response to Comments
EPA proposed the method updates in today's rule on January 16, 2001
(66 FR 3526). The public comment period closed on March 19, 2001. EPA
received comments from one commenter. A discussion of the significant
comments follows. A complete copy of the comments and EPA's responses
are included in the Docket for today's final rule.
A. Approving Multiple Editions of Standard Methods
The commenter stated that approval of multiple editions of Standard
Methods is a new requirement and an added burden to the regulatory
authorities that must keep track of all approved methods. EPA disagrees
that tracking multiple editions of Standard Methods is a new
requirement or unduly burdensome. The Agency currently cites more than
one edition of the same method, e.g. footnote 4 to the table of
inorganic methods at 40 CFR 141.23 allows use of either the 18th or
19th edition versions of all the Standard Methods listed in the table.
For this reason, the Agency always cites an approved method by both
method number and date (or edition) of publication to avoid confusion
about which versions are approved, and to allow incorporation of the
method by reference in the CFR in lieu of publication of the entire
method in the CFR. This citation policy means that existing State
databases would be designed to accommodate the edition as well as the
number of an approved method so that multiple versions of an approved
method can be tracked.
EPA recognizes that there are tradeoffs between the current
approach of allowing use of several versions of a test method, and the
suggested revision (received in a comment) to allow only the most
recent version of that method. Allowing use of only the 20th edition of
Standard Methods may have more consequences than just the purchase of
the 20th edition book. A laboratory may routinely use only a few
methods that are published in Standard Methods, and these may be
methods that have been reprinted in the 20th edition with no editorial
or technical changes. Under the suggested revision to allow use of only
the 20th edition of Standard Methods, a laboratory may be required to
update method citations in existing quality assurance manuals and
laboratory standard operating procedures as well as provide analysts
with a copy of the 20th edition version of the method even when the
methods have not changed from previous editions.
Furthermore, withdrawal of previous editions of Standard Methods
was not proposed for public comment in the January 2001 rule, and the
suggestion to allow use of only the 20th edition of Standard Methods is
outside the scope of today's regulatory amendments. Public comment on
previous proposals to withdraw older versions of methods, indicated
that most laboratories prefer the flexibility to use these versions if
the methods have not changed significantly in new editions of the
manuals. Thus, EPA continues to allow use of older editions of Standard
Methods.
B. Technical Differences Between Methods
The commenter suggested that some methods in the 18th edition of
Standard Methods are obsolete because of technical and editorial
updates in newer editions. EPA disagrees that the methods in the 18th
edition of Standard Methods approved in today's rule are obsolete.
The methods approved by today's rule are technically equivalent to
previously approved versions. Only methods using time-tested
technologies are approved by today's rule. For the purposes of
compliance monitoring, however, none of these methods are obsolete and
all methods provide the necessary technical information. Therefore, EPA
believes the use of previously approved editions of Standard Methods
continues to be appropriate.
C. Withdrawing Methods That Use Older Technology
The commenter suggested colorimetric methods for trace metals
analysis, with the exception of hexavalent chromium, be dropped from
the list of approved methods at 40 CFR part 136, Table IB, arguing that
these methods are obsolete. The commenter stated that many of these
methods list interferences not encountered by atomic absorption, atomic
emission, or mass spectrometry techniques. The commenter also stated
that many of these methods also increase the amount of hazardous waste
generated in the laboratory and that the detection limits attained by
the colorimetric methods may not be low enough to meet permit
requirements. EPA disagrees for several reasons.
Colorimetric metals methods have been in use a long time, and
explain how to handle the analytical difficulties noted by the
commenter. Although many of the colorimetric methods have the potential
to generate more laboratory wastes than some newer methods, these
methods produce acceptable compliance monitoring information, and the
commenter did not provide any data to demonstrate otherwise.
Colorimetric methods often provide a low-cost alternative to high
energy analysis methods that have high labor and equipment costs.
Finally, withdrawal of these methods was not proposed for public
comment and is outside the scope of today's amendments.
D. Digestion Preceding Sample Analysis
The commenter noted that 40 CFR part 136.3, Table IB, parameter 31,
referring to total Kjeldahl nitrogen (TKN), specifies ``digestion and
distillation followed by'' one of several new techniques. The commenter
asked if ``digestion and distillation followed by'' means that
digestion and distillation are required prior to analysis of a sample
for NPDES compliance monitoring. EPA requires the use of separate
digestion and distillation procedures prior to TKN analysis by certain
methods, as specified in Table IB. ``Digestion and distillation
followed by,'' in the context of Table IB, requires the use of one of
the listed digestion and distillation procedures for the Titration,
Nesslerization and Electrode test methods. Today's rule reformats Table
IB with appropriate indentation to reflect this requirement more
clearly.
Other TKN methods explicitly require alternate sample preparation
procedures, such as the semiautomated block digestion (e.g., EPA Method
351.2). For these methods, TKN analysis does not require the use the
digestion and distillation procedures discussed in the preceding
paragraph, because the alternate sample preparation procedures will
provide the desired results.
E. Metals Methods in 20th Edition of Standard Methods
The commenter inquired about the status of the graphite furnace and
flame atomic absorption methods for metals analyses (GFAA and FLAA,
respectively) that were revised in the 20th edition of Standard
Methods, but not proposed for approval in the January 16, 2001 rule.
The commenter recommended that EPA either approve or not approve all
versions (18th, 19th and 20th edition) and not split approval of these
methods by edition number. EPA did not propose, and today's rule does
not approve, the 20th Edition versions of Methods 3111B, 3111D,
[[Page 65224]]
3112 B, 3113 B and 3114 B, which include the GFAA and FLAA methods
noted by the commenter. These versions of the five methods are not
acceptable because the method performance requirements specified in the
20th edition are not equivalent or better than in the 18th and 19th
edition versions of these methods. The 20th edition of Standard Methods
introduces less stringent quality control (QC) acceptance criteria (in
Section 3020 of each method) than in the older versions. Specifically,
the 18th and 19th edition versions specify that a recovery of a check
standard outside the range of 95% to 105% suggests a potential problem,
and a recovery outside the range of 90% to 110% indicates that the
system is out of control. The 20th edition weakened and increased these
limits to 90% to 100% and 80% to 120%, respectively. The editors of
Standard Methods did not provide a basis for weakening the QC
requirements in these methods, and they did not suggest applying these
less stringent criteria to previous editions of the methods.
VI. Administrative Requirements
A. Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866 (58 FR 51735; October 4, 1993), the
Agency must determine whether the regulatory action is ``significant''
and, therefore, subject to OMB review and the requirements of the
Executive Order. The Order defines ``significant regulatory action'' as
one that is likely to result in a rule that may:
(1) Have an annual effect on the economy of $100 million or more,
or adversely affect in a material way the economy, a sector of the
economy, productivity, competition, jobs, the environment, public
health or safety, or State, local, or Tribal governments or
communities;
(2) Create a serious inconsistency or otherwise interfere with an
action taken or planned by another agency;
(3) Materially alter the budgetary impact of entitlements, grants,
user fees, or loan programs or the rights and obligations of recipients
thereof; or
(4) Raise novel legal or policy issues arising out of legal
mandates, the President's priorities, or the principles set forth in
the Executive Order.
It has been determined that this rule is not a ``significant
regulatory action'' under the terms of Executive Order 12866 and is
therefore not subject to OMB review.
B. Regulatory Flexibility Act (RFA), as Amended by the Small Business
Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. 601 et.
seq.
The RFA generally requires an agency to prepare a regulatory
flexibility analysis of any rule subject to notice and comment
rulemaking requirements under the Administrative Procedure Act or any
other statute unless the agency certifies that the rule will not have a
significant economic impact on a substantial number of small entities.
Small entities include small businesses, small organizations, and small
governmental jurisdictions.
The RFA provides default definitions for each type of small entity.
It also authorizes an agency to use alternative definitions for each
category of small entity, ``which are appropriate to the activities of
the agency'' after proposing the alternative definition(s) in the
Federal Register and taking comment (5 U.S.C. 601(3)-(5).) In addition
to the above, to establish an alternative small business definition,
agencies must consult with the Small Business Administration's (SBA)
Chief Counsel for Advocacy.
For purposes of assessing the impacts of today's rule on small
entities under the SDWA, EPA considered small entities to be public
water systems serving fewer than 10,000 persons. This is the cut-off
level specified by Congress in the 1996 Amendments to the SDWA for
small system flexibility provisions. In accordance with the RFA
requirements, EPA proposed using this alternative definition in the
Federal Register (63 FR 7620, February 13, 1998), requested comment,
consulted with the SBA, and expressed its intention to use the
alternative definition for all future drinking water regulations in the
Consumer Confidence Reports regulation (63 FR 44511, August 19, 1998).
As stated in that final rule, the alternative definition would be
applied to this regulation as well.
For purposes of assessing the impacts of today's rule on small
entities under the CWA, we defined: (1) Small businesses according to
SBA size standards; (2) small governmental jurisdictions as governments
of a city, county, town, school district or special district with a
population of less than 50,000; and (3) small organizations as any not-
for-profit enterprise which is independently owned and operated and is
not dominant in its field.
After considering the economic impacts of today's final rule on
small entities, I certify that this action will not have a significant
economic impact on a substantial number of small entities. This final
rule will not impose any requirements on small entities. Today's rule
approves additional updated versions of ASTM Methods, Standard Methods,
United States Geological Survey (USGS) methods, and United States
Department of Energy (DOE) methods for compliance with wastewater
monitoring and drinking water standards and monitoring requirements but
does not require the use of these specific versions. Previous versions
of these ASTM, Standard Methods, USGS, and DOE methods are not being
withdrawn. State, territorial, Tribal, and local governments and public
and privately owned public water systems and laboratories performing
analyses on behalf of these systems may continue to use the previous
versions after the promulgation of today's rule. The final rule merely
provides additional options. Any of the testing procedures currently
listed at 40 CFR parts 136, 141, or 143 can be used if monitoring is
otherwise required for this pollutant under the CWA or SDWA. This rule
also makes minor technical corrections and clarifications to the
regulations.
C. Unfunded Mandates Reform Act
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public
Law 104-4, establishes requirements for Federal agencies to assess the
effects of their regulatory actions on State, local, and Tribal
governments and the private sector. Under section 202 of the UMRA, EPA
generally must prepare a written statement, including a cost-benefit
analysis, for proposed and final rules with ``Federal mandates'' that
may result in expenditures to State, local, and Tribal governments, in
the aggregate, or to the private sector, of $100 million or more in any
one year. Before promulgating an EPA rule for which a written statement
is needed, section 205 of the UMRA generally requires EPA to identify
and consider a reasonable number of regulatory alternatives and adopt
the least costly, most cost-effective or least burdensome alternative
that achieves the objectives of the rule. The provisions of section 205
do not apply when they are inconsistent with applicable law. Moreover,
section 205 allows EPA to adopt an alternative other than the least
costly, most cost-effective or least burdensome alternative if the
Administrator publishes with the final rule an explanation why that
alternative was not adopted.
Before EPA establishes any regulatory requirements that may
significantly or uniquely affect small governments, including Tribal
governments, it must
[[Page 65225]]
have developed under section 203 of the UMRA a small government agency
plan. The plan must provide for notifying potentially affected small
governments, enabling officials of affected small governments to have
meaningful and timely input in the development of EPA regulatory
proposals with significant Federal intergovernmental mandates, and
informing, educating, and advising small governments on compliance with
the regulatory requirements.
Today's rule contains no Federal mandates (under the regulatory
provisions of Title II of the UMRA) for State, local, or Tribal
governments or the private sector. This rule imposes no enforceable
duty on any State, local or Tribal governments or the private sector.
EPA has determined that this rule contains no regulatory requirements
that might significantly or uniquely affect small governments. Thus,
today's rule is not subject to the requirements of sections 202, 203,
and 205 of the UMRA.
This rule provides additional analytical methods with which to
conduct analyses for contaminants in wastewater and drinking water, and
thus provides operational flexibility to laboratory analysts. Since the
rule does not withdraw earlier versions of methods, EPA anticipates no
increase in expenditure or burden.
D. Paperwork Reduction Act
This action does not impose an information collection burden under
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq.
This action merely provides additional options on the selection of
testing procedures when monitoring is otherwise required under the CWA
or SDWA. Any of the testing procedures approved at 40 CFR parts 136,
141, or 143 can be used if such monitoring is required for a pollutant
or contaminant. Burden means the total time, effort, or financial
resources expended by persons to generate, maintain, retain or disclose
or provide information to or for a Federal agency. This includes the
time needed to review instructions; develop, acquire, install, and
utilize technology and systems for the purpose of collecting,
validating, and verifying information processing and maintaining
information, and disclosing and providing information; adjust the
existing ways to comply with any previously applicable instructions and
requirements; train personnel to be able to respond to a collection of
information; search data sources; complete and review the collection of
information; and transmit or otherwise disclose the information.
An agency may not conduct or sponsor, and a person is not required
to respond to a collection of information unless it displays a
currently valid OMB control number. The OMB control numbers for EPA's
regulations are listed in 40 CFR part 9 and 48 CFR Chapter 15.
E. National Technology Transfer and Advancement Act
As noted in the proposed rule, Section 12(d) of the National
Technology Transfer and Advancement Act of 1995, (``NTTAA''), Public
Law 104-113, section 12(d) (15 U.S.C. 272 note), directs EPA to use
voluntary consensus standards in its regulatory activities unless to do
so would be inconsistent with applicable law or otherwise impractical.
Voluntary consensus standards are technical standards (e.g., material
specifications, test methods, sampling procedures, and business
practices) that are developed or adopted by voluntary consensus
standard bodies. The NTTAA directs EPA to provide Congress, through the
Office of Management and Budget (OMB), explanations when the Agency
decides not to use available and applicable voluntary consensus
standards. In this rulemaking EPA is approving updated versions of
previously approved voluntary consensus standards published by ASTM and
Standard Methods for many wastewater and drinking water contaminants.
F. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
Executive Order 13045 (62 FR 19885, April 23, 1997) applies to any
rule that: (1) Is determined to be ``economically significant'' as
defined under Executive Order 12866, and (2) concerns an environmental
health or safety risk that EPA has reason to believe may have a
disproportionate effect on children. If the regulatory action meets
both criteria, the Agency must evaluate the environmental health or
safety effects of the planned rule on children, and explain why the
planned regulation is preferable to other potentially effective and
reasonably feasible alternatives considered by the Agency. This rule is
not subject to Executive Order 13045 because it is neither
``economically significant'' as defined under Executive Order 12866,
nor does it concern an environmental health or safety risk that EPA has
reason to believe may have a disproportionate effect on children.
G. Executive Order 13132: Federalism
Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August
10, 1999), requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive Order to include regulations that have ``substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.''
This final rule does not have federalism implications. It will not
have substantial direct effects on the States, on the relationship
between the national government and the States, or on the distribution
of power and responsibilities among the various levels of government,
as specified in Executive Order 13132. Today's rule provides
governmental and other public and private entities conducting analysis
in wastewater and drinking water the option to use additional, updated
analytical methods to monitor pollutants under the CWA or SDWA. Such
regulated entities may choose any of these additional methods or
continue to use the methods listed under 40 CFR parts 136, 141, and
143. Thus, Executive Order 13132 does not apply to this rule.
H. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
Executive Order 13175, entitled ``Consultation and Coordination
with Indian Tribal Governments'' (59 FR 22951, November 9, 2000),
requires EPA to develop an accountable process to ensure ``meaningful
and timely input by Tribal officials in the development of regulatory
policies that have tribal implications.'' ``Policies that have tribal
implications'' is defined in the Executive Order to include regulations
that have ``substantial direct effects on one or more Indian tribes, on
the relationship between the Federal government and the Indian tribes,
or on the distribution of power and responsibilities between the
Federal government and the Indian tribes.''
This final rule does not have tribal implications. It will not have
substantial direct effects on tribal governments, on the relationship
between the Federal government and Indian tribes, or on the
distribution of power and responsibilities between the Federal
government and Indian tribes, as specified in Executive Order 13175.
[[Page 65226]]
Today's rule provides Tribes conducting analysis in wastewater and
drinking water the option to use additional updated analytical methods
to monitor pollutants under the CWA or SDWA. Tribes may choose any of
these additional methods or continue to use the methods listed under 40
CFR parts 136, 141, and 143. Thus, Executive Order 13175 does not apply
to this rule.
I. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA),
generally provides that before a rule may take effect, the agency
promulgating the rule must submit a rule report, which includes a copy
of the rule, to each House of the Congress and to the Comptroller
General of the United States. EPA will submit a report containing this
rule and other required information to the U.S. Senate, the U.S. House
of Representatives, and the Comptroller General of the United States
prior to publication of the rule in the Federal Register. A major rule
cannot take effect until 60 days after it is published in the Federal
Register. This action is not a ``major rule'' as defined by 5 U.S.C.
804(2). This rule will be effective on November 22, 2002.
J. Executive Order 13211: Energy Effects
This rule is not subject to Executive Order 13211, ``Actions
Concerning Regulations That Significantly Affect Energy Supply,
Distribution, or Use'' (66 FR 28355, May 22, 2001) because it is not a
significant regulatory action under Executive Order 12866.
K. Plain Language Directive
Executive Order 12866 requires each agency to write its rules in
plain language. Readable regulations help the public find requirements
quickly and understand them easily. They increase compliance,
strengthen enforcement, and decrease mistakes, frustration, phone
calls, appeals, and distrust of government. EPA made every effort to
write this preamble to the final rule in as clear, concise, and
unambiguous manner as possible. Today's final rule is mostly in a table
format consistent with the format of the CFR sections we are amending.

For the reasons set out in the preamble, title 40, chapter I of the
Code of Federal Regulations, is amended as follows:
PART 136--GUIDELINES ESTABLISHING TEST PROCEDURES FOR THE ANALYSIS
OF POLLUTANTS
1. The authority citation for part 136 continues to read as
follows:
Authority: Secs. 301, 304(h), 307, and 501(a) Pub. L. 95-217, 91
Stat. 1566, et seq. (33 U.S.C. 1251, et seq.) (The Federal Water
Pollution Control Act Amendments of 1972 as amended by the Clean
Water Act of 1977.)
2. Section 136.3 is amended:
a. In paragraph (a) by revising the introductory text and Tables
IA, IB, IC, ID, and IE.
b. In paragraph (b) by revising references (6) and (10), and adding
references (44) through (51).
Sec. 136.3 Identification of test procedures.
(a) Parameters or pollutants, for which methods are approved, are
listed together with test procedure descriptions and references in
Tables IA, IB, IC, ID, IE, and IF. The full text of the referenced test
procedures are incorporated by reference into Tables IA, IB, IC, ID,
IE, and IF. The incorporation by reference of these documents, as
specified in paragraph (b) of this section, was approved by the
Director of the Federal Register in accordance with 5 U.S.C. 552(a) and
1 CFR part 51. Copies of the documents may be obtained from the sources
listed in paragraph (b) of this section. Information regarding
obtaining these documents can be obtained from the EPA Office of Water
Statistics and Analytical Support Branch at 202-566-1000. Documents may
be inspected at EPA's Water Docket, EPA West, 1301 Constitution Avenue,
NW., Room B135, Washington, DC (Telephone: 202-566-2426); or at the
Office of the Federal Register, 800 North Capitol Street, NW., Suite
700, Washington, DC. These test procedures are incorporated as they
exist on the day of approval and a notice of anys change in these test
procedures will be published in the Federal Register. The discharge
parameter values for which reports are required must be determined by
one of the standard analytical test procedures incorporated by
reference and described in Tables IA, IB, IC, IE, and IF, or by any
alternate test procedure which has been approved by the Administrator
under the provisions of paragraph (d) of this section and Sec. Sec.
136.4 and 136.5. Under certain circumstances (paragraph (b) or (c) of
this section or 40 CFR 401.13) other test procedures may be more
advantageous when such other test procedures have been previously
approved by the Regional Administrator of the Region in which the
discharge will occur, and providing the Director of the State in which
such discharge will occur does not object to the use of such alternate
test procedure.

\3\ ``Official Methods of Analysis of the Association of Official Analytical Chemists,'' methods manual, 15th ed. (1990).
\4\ For the determination of total metals the sample is not filtered before processing. A digestion procedure is required to solubilize suspended material and to destroy possible organic-metal
complexes. Two digestion procedures are given in ``Methods for Chemical Analysis of Water and Wastes, 1979 and 1983''. One (Section 4.1.3), is a vigorous digestion using nitric acid. A less
vigorous digestion using nitric and hydrochloric acids (Section 4.1.4) is preferred; however, the analyst should be cautioned that this mild digestion may not suffice for all samples types.
Particularly, if a colorimetric procedure is to be employed, it is necessary to ensure that all organo-metallic bonds be broken so that the metal is in a reactive state. In those situations,
the vigorous digestion is to be preferred making certain that at no time does the sample go to dryness. Samples containing large amounts of organic materials may also benefit by this
vigorous digestion, however, vigorous digestion with concentrated nitric acid will convert antimony and tin to insoluble oxides and render them unavailable for analysis. Use of ICP/AES as
well as determinations for certain elements such as antimony, arsenic, the noble metals, mercury, selenium, silver, tin, and titanium require a modified sample digestion procedure and in all
cases the method write-up should be consulted for specific instructions and/or cautions.
Note to Table 1B Note 4: If the digestion procedure for direct aspiration AA included in one of the other approved references is different than the above, the EPA procedure must be used.
Dissolved metals are defined as those constituents which will pass through a 0.45 micron membrane filter. Following filtration of the sample, the referenced procedure for total metals must
be followed. Sample digestion of the filtrate for dissolved metals (or digestion of the original sample solution for total metals) may be omitted for AA (direct aspiration or graphite
furnace) and ICP analyses, provided the sample solution to be analyzed meets the following criteria:
a. has a low COD (<20)
b. is visibly transparent with a turbidity measurement of 1 NTU or less
c. is colorless with no perceptible odor, and
d. is of one liquid phase and free of particulate or suspended matter following acidification.

\12\ Carbonaceous biochemical oxygen demand (CBOD5) must not be confused with the traditional BOD5 test method which measures ``total BOD''. The addition of the nitrification inhibitor is not
a procedural option, but must be included to report the CBOD5 parameter. A discharger whose permit requires reporting the traditional BOD5 may not use a nitrification inhibitor in the
procedure for reporting the results. Only when a discharger's permit specifically states CBOD5 is required can the permittee report data using a nitrification inhibitor.

\29\ Approved methods for the analysis of silver in industrial wastewaters at concentrations of 1 mg/L and above are inadequate where silver exists as an inorganic halide. Silver halides such
as the bromide and chloride are relatively insoluble in reagents such as nitric acid but are readily soluble in an aqueous buffer of sodium thiosulfate and sodium hydroxide to pH of 12.
Therefore, for levels of silver above 1 mg/L, 20 mL of sample should be diluted to 100 mL by adding 40 mL each of 2 M Na2S2O3 and NaOH. Standards should be prepared in the same manner. For
levels of silver below 1 mg/L the approved method is satisfactory.

Table IC notes:
\1\ All parameters are expressed in micrograms per liter ([mu]g/L) except for Method 1613B in which the parameters are expressed in picograms per liter
(pg/L).
\2\ The full text of Methods 601-613, 624, 625, 1624B, and 1625B, are given at Appendix A, ``Test Procedures for Analysis of Organic Pollutants,'' of
this Part 136. The full text of Method 1613B is incorporated by reference into this Part 136 and is available from the National Technical Information
Services as stock number PB95-104774. The standardized test procedure to be used to determine the method detection limit (MDL) for these test
procedures is given at Appendix B, ``Definition and Procedure for the Determination of the Method Detection Limit,'' of this Part 136.

Agency, September, 1978.
\4\ Method 624 may be extended to screen samples for Acrolein and Acrylonitrile. However, when they are known to be present, the preferred method for
these two compounds is Method 603 or Method 1624B.
\5\ Method 625 may be extended to include benzidine, hexachlorocyclopentadiene, N-nitrosodimethylamine, and N-nitrosodiphenylamine. However, when they
are known to be present, Methods 605, 607, and 612, orMethod 1625B, are preferred methods for these compounds.

Standard Methods for the Examination of Water and Wastewater (1981).
\7\ Each Analyst must make an initial, one-time demonstration of their ability to generate acceptable precision and accuracy with Methods 601-603, 624,
625, 1624B, and 1625B (See Appendix A of this Part 136) in accordance with procedures each in Section 8.2 of each of these Methods. Additionally, each
laboratory, on an on-going basis must spike and analyze 10% (5% for Methods 624 and 625 and 100% for methods 1624B and 1625B) of all samples to
monitor and evaluate laboratory data quality in accordance with Sections 8.3 and 8.4 of these Methods. When the recovery of any parameter falls
outside the warning limits, the analytical results for that parameter in the unspiked sample are suspect and cannot be reported to demonstrate
regulatory compliance.

Survey, Book 5, Chapter A3 (1987).
\5\ The method may be extended to include [alpha]-BHC, [gamma]-BHC, endosulfan I, endosulfan II, and endrin. However, when they are known to exist,
Method 608 is the preferred method.
\6\ ``Selected Analytical Methods Approved and Cited by the United States Environmental Protection Agency.'' Supplement to the Fifteenth Edition of
Standard Methods for the Examination of Water and Wastewater (1981).
\7\ Each analyst must make an initial, one-time, demonstration of their ability to generate acceptable precision and accuracy with Methods 608 and 625
(See Appendix A of this Part 136) in accordance with procedures given in Section 8.2 of each of these methods. Additionally, each laboratory, on an on-
going basis, must spike and analyze 10% of all samples analyzed with Method 608 or 5% of all samples analyzed with Method 625 to monitor and evaluate
laboratory data quality in accordance with Sections 8.3 and 8.4 of these methods. When the recovery of any parameter falls outside the warning limits,
the analytical results for that parameter in the unspiked sample are suspect and cannot be reported to demonstrate regulatory compliance. These
quality control requirements also apply to the Standard Methods, ASTM Methods, and other Methods cited.
Note: These warning limits are promulgated as an ``Interim final action with a request for comments.''

(i) EC medium supplemented with 50 [mu]g/mL of 4-
methylumbelliferyl-beta-D-glucuronide (MUG) (final concentration), as
described in Method 9222G in Standard Methods for the Examination of
Water and Wastewater, 19th edition (1995) and 20th edition (1998).
Either edition may be used. Alternatively, the 18th edition (1992) may
be used if at least 10 mL of EC medium, as described in paragraph
(f)(5) of this section, is supplemented with 50 [mu]g/mL of MUG before
autoclaving. The inner inverted fermentation tube may be omitted. If
the 18th edition is used, apply the procedure in paragraph (f)(5) of
this section for transferring a total coliform-positive culture to EC
medium supplemented with MUG, incubate the tube at 44.5 +/- 0.2[deg]C
for 24 +/- 2 hours, and then observe fluorescence with an ultraviolet
light (366 nm) in the dark. If fluorescence is visible, E. coli are
present.
(ii) Nutrient agar supplemented with 100 [mu]g/mL of 4-
methylumbelliferyl-beta-D-glucuronide (MUG) (final concentration), as
described in Method 9222G in Standard Methods for the Examination of
Water and Wastewater, 19th edition (1995) and 20th edition (1998).
Either edition may be used for determining if a total coliform-positive
sample, as determined by a membrane filter technique, contains E. coli.
Alternatively, the 18th edition (1992) may be used if the membrane
filter containing a total coliform-positive colony(ies) is transferred
to nutrient agar, as described in Method 9221B (paragraph 3) of
Standard Methods (18th edition), supplemented with 100 [mu]g/mL of MUG.
If the 18th edition is used, incubate the agar plate at 35[deg]C for 4
hours and then observe the colony(ies) under ultraviolet light (366 nm)
in the dark for fluorescence. If fluorescence is visible, E. coli are
present.

\12\ Unfiltered, no digestion or hydrolysis.
\13\ Because MDLs reported in EPA Methods 200.7 and 200.9 were determined using a 2X preconcentration step during sample digestion, MDLs determined when samples are analyzed by direct analysis
(i.e., no sample digestion) will be higher. For direct analysis of cadmium and arsenic by Method 200.7, and arsenic by Method 3120 B sample preconcentration using pneumatic nebulization may
be required to achieve lower detection limits. Preconcentration may also be required for direct analysis of antimony, lead, and thallium by Method 200.9; antimony and lead by Method 3113 B;
and lead by Method D3559-90D unless multiple in-furnace depositions are made.
[[Page 65250]]
\14\ If ultrasonic nebulization is used in the determination of arsenic by Methods 200.7, 200.8, or SM 3120 B, the arsenic must be in the pentavalent state to provide uniform signal response.
For methods 200.7 and 3120 B, both samples and standards must be diluted in the same mixed acid matrix concentration of nitric and hydrochloric acid with the addition of 100 [mu]L of 30%
hydrogen peroxide per 100ml of solution. For direct analysis of arsenic with method 200.8 using ultrasonic nebulization, samples and standards must contain one mg/L of sodium hypochlorite.
\15\ After January 23, 2006 analytical methods using the ICP-AES technology, may not be used because the detection limits for these methods are 0.008 mg/L or higher. This restriction means
that the two ICP-AES methods (EPA Method 200.7 and SM 3120 B) approved for use for the MCL of 0.05 mg/L may not be used for compliance determinations for the revised MCL of 0.01 mg/L.
However, prior to 2005 systems may have compliance samples analyzed with these less sensitive methods.
