Additional Flexibility Amendments to Vehicle Inspection
Maintenance Program Requirements; Proposed Amendment to the Final Rule
AGENCY: Environmental Protection Agency.
ACTION: Notice of proposed rulemaking.
-----------------------------------------------------------------------
SUMMARY: This document proposes several substantive and minor revisions
to the Motor Vehicle Inspection/Maintenance (I/M) requirements to
provide additional flexibility to state I/M programs, both in response
to the I/M provisions of the National Highway System Designation Act of
1995 (NHSDA), and in compliance with the Clean Air Act requirement that
EPA's guidance for such programs be ``from time to time revised.'' The
proposed amendments would: modify the current I/M performance standard
modeling requirements to reflect delays caused by the NHSDA, and to
provide states greater flexibility in how they meet the performance
standard; also in response to the NHSDA, remove the I/M rule provision
establishing the decentralized, test-and-repair credit discount; revise
certain test procedure, standard, and equipment requirements to better
accommodate alternative test types and program designs. This revision
also entails changing the data collection, analysis, and reporting
requirements to make them consistent with various alternative test and
program types; as well as minor revisions to the inspector training
requirements; revise the requirements for consumer protection and
improving repair effectiveness to limit the current requirement to
provide diagnostic information to those programs and test types capable
of producing such information, reliably and practically; expand the
options for complying with the on-road testing requirement to
accommodate more recent variations, such as clean screening and non-
tailpipe based, roadside tests.
DATES: Written comments on this proposal must be received no later than
September 20, 1999. No public hearing will be held unless a request is
received in writing by September 7, 1999.

II. Summary of Proposal
Under the Clean Air Act as amended in 1990 (CAA), 42 U.S.C. 7401 et
seq., the U.S. Environmental Protection Agency (EPA) published in the
Federal Register on November 5, 1992, (40 CFR part 51, subpart S) a
rule related to state air quality implementation plans for Motor
Vehicle Inspection and Maintenance (I/M) programs (hereafter referred
to as the I/M rule; see 57 FR 52950). EPA is proposing today to further
amend this rule to provide greater flexibility to states to tailor
their I/M programs to better meet local needs, both now and in the
future. With today's notice EPA proposes to: (1) Amend the enhanced I/M
performance standard requirements at 40 CFR 51.351 to change the
performance standard modeling requirement from demonstrating that the
performance standard is met on 2000 and each subsequent milestone
(through to and including the attainment deadline) to a requirement
that the performance standard be met (within +/- 0.02 grams-per-mile)
on 2002, and that the same or better level of emission reduction be
demonstrated for the attainment deadline, rounded to the nearest year;
(2) in response to the National Highway System Designation Act of 1995
(NHSDA) and to provide greater flexibility to the states with regard to
network design options: (a) Delete 40 CFR 51.353(b) which previously
established the decentralized, test-and-repair credit discount, and (b)
revise the definition of test-only at 40 CFR 51.353(a) to allow test-
only stations to sell self-serve gasoline, pre-packaged oil, and any
other items that are not directly related to automotive parts sales
and/or service; (3) to better accommodate alternative test types and
program designs: (a) Revise the test procedures and standards
requirements at 40 CFR 51.357 to clarify that tailpipe exhaust testing
is not a universal requirement for all I/M programs, that alternatives
to the IM240 drive cycle are allowed under the requirements for
transient testing, and that the standard for an acceptable alternative
test is comparability, not necessarily equivalence, (b) revise the test
equipment requirements at 40 CFR 51.358 to make the definition of
``computerized analyzer'' less prescriptive and to relax the
requirement for a real-time data link for those areas required to do I/
M, but which do not need to claim I/M emission reductions to meet their
other, non-I/M CAA requirements, and (c) revise the data collection,
analysis, and reporting requirements at 40 CFR 51.365 and 40 CFR 51.366
to clarify that the specific elements to be collected and reported are
only required where applicable to the test type employed, and to make
the requirements less prescriptive with regard to the test types
assumed; (4) revise the requirements for consumer protection at 40 CFR
51.368 and improving repair effectiveness at 40 CFR 51.369 to limit the
current requirement to provide diagnostic information to those programs
and test types capable of producing such information, reliably and
practically, and; (5) expand the options for complying with the on-road
testing requirement at 40 CFR 51.371 by: (a) Removing language
suggesting that such testing must be tailpipe-based, and (b) inserting
language making the out-of-cycle repair requirement optional where on-
road testing is used as a clean-screen approach.
The goal of these proposed amendments is to bring the rule up-to-
date with current policy decisions and statutory requirements, while
also providing states the additional flexibility they need to tailor
their I/M programs now to better meet their future needs. Among these
future needs are: (1) The need to maximize program efficiency and
customer convenience by capitalizing on newer vehicle testing options,
such as on-board diagnostic (OBD) system testing; (2) the need to
accommodate an in-use fleet turning over to newer, cleaner, and more
durable vehicle technologies over time; and (3) the need to assess the
role I/M should play in areas once they have attained the National
Ambient Air Quality Standards (NAAQS).
III. Authority
Authority for the rule change proposed in this notice is granted to
EPA by section 182 of the Clean Air Act as amended (42 U.S.C. 7401, et
seq.) and by section 348 of the National Highway System Designation Act
of 1995 (23 U.S.C. 101).
IV. Background of the Proposed Amendments
A. Performance Standard Amendments
Section 182(c)(3)(B)(i) of the Clean Air Act as amended in 1990
requires EPA to develop a performance standard for enhanced I/M areas
to meet. EPA's I/M rule currently requires I/M programs to produce the
same or better emission reductions as would be achieved by one of three
possible enhanced I/M performance standards 1--the high
enhanced, low enhanced, and OTR low enhanced I/M performance standards.
Currently, states demonstrate meeting the relevant performance standard
by modeling their desired program along side the performance standard
program, and comparing both to a no-I/M-program scenario, using the
most current version of EPA's mobile source emission factor model,
MOBILE, and assuming local conditions for fuel type, average
temperature, fleet age distribution, vehicle miles traveled (VMT)
accumulation, etc. The 1992 I/M rule required that enhanced I/M
programs show they could meet the relevant performance standard
beginning with a 2000 evaluation date (which was considered the closest
modeling equivalent to the CAA's November 15, 1999 milestone date for
Reasonable Further Progress) and for each CAA milestone thereafter
(also rounded to the nearest evaluation year) through, to and including
the relevant attainment date. EPA's policy for milestones beginning
with 2003 and later was to consider the standard met if the projected
emission reductions for the state's program came within
<plus-minus>0.02 grams-per-mile (gpm) of the performance standard's
projected reductions, due to the uncertainty of modeled benefits for
evaluation years after 2001.
---------------------------------------------------------------------------
\1\ The current I/M rule actually contains four enhanced I/M
performance standards as a result of a typographical oversight when
EPA introduced its original flexibility amendments in 1995. EPA
intended to delete the standard described in 40 CFR 51.351(a) and
replace it with the standard described in paragraph (f) of that
section. Unfortunately, both standards were retained. Along with the
other actions proposed today, EPA proposes to correct this
oversight.
---------------------------------------------------------------------------
Today's proposal would change the current enhanced I/M performance
standard requirements in three ways:
First, today's proposal would change the requirement that enhanced
I/M programs demonstrate meeting the performance standard beginning
with 2000 and on each subsequent milestone through to and including
attainment. Due to delays in program implementation arising from EPA's
own 1995 and 1996 I/M flexibility amendments and the I/M provisions of
the NHSDA, EPA proposes to push back the first required evaluation date
by two years, to 2002. This proposed revision recognizes that as a
result many programs delayed full implementation beyond a date that
would allow for
[[Page 45493]]
meeting the performance standard before 2002.
Second, EPA proposes to reduce the modeling burden on states by
limiting the number of milestones modeled to a maximum of two: 2002
and, for those areas with post-2002 attainment deadlines, the relevant
CAA attainment deadline, rounded up to the nearest year. In the latter
case--the attainment deadline milestone--the grams-per-mile (gpm) or
percent reduction target for comparison would be the same as that
modeled for the 2002 milestone; states would not be required to model
the performance standard scenario for more than one evaluation date to
establish the relevant gpm or percent reduction target. Rather, states
must show that in the attainment year the area continues to show
compliance with the performance standard as originally modeled for the
2002 compliance date. The purpose of this proposal is to streamline the
I/M rule's modeling requirements and provide additional flexibility to
the states, while still insuring that state I/M programs demonstrate
compliance with the relevant performance standard.
Third, today's proposal would apply the current 2003
<plus-minus>0.02 gpm rounding policy one year earlier--to the 2002
milestone. The original 2003 rounding policy was developed when it was
discovered that, due to uncertainties related to long-term projections,
even areas adopting EPA's recommended program appeared to be having
trouble demonstrating compliance with the performance standard for
post-2001 milestones, once local parameters such as vehicle age
distribution were taken into consideration. Under the original I/M
rule, there was no 2002 milestone. Instead, the ozone-based milestones
began with 2000, followed by 2003; in between these was the carbon
monoxide (CO) milestone of 2001, for those enhanced I/M areas in
nonattainment for CO. The original 0.02 gpm rounding policy was
actually a post-2001 policy, and was applied to what was then the first
post-2001 milestone (i.e., 2003). With the delays caused by the I/M
flexibility amendments and the NHSDA (discussed above), a new post-2001
milestone became necessary. EPA believes it is therefore appropriate to
apply the 0.02 gpm rounding policy to this new milestone, and proposes
to formalize that change as part of today's proposed amendments.
B. Network Requirement Amendments
Regarding I/M program network design requirements, the Clean Air
Act as amended in 1990 does not prescribe a network for basic I/M
programs while, at the same time, section 182(c)(3)(C)(vi) of the Act
requires that enhanced I/M programs shall be operated ``on a
centralized basis, unless the State demonstrates to the satisfaction of
the Administrator that a decentralized program will be equally
effective.'' In response to this provision, the 1992 I/M rule defined a
decentralized network design that EPA deemed presumptively equivalent
to a centralized program. The core difference between traditional
centralized versus decentralized I/M programs--EPA then maintained--was
the conflict-of-interest the latter were assumed to suffer from,
because most such programs allowed the same individuals who tested the
vehicle to also perform repairs and then retest the vehicle to
determine the effectiveness of those repairs. It was therefore
concluded that a decentralized program that separated these functions
(i.e., a so-called ``test-only'' program) would be presumptively
equivalent to a centralized program. In May 1994, EPA issued a policy
document entitled, ``EPA Policy on Decentralized, Test-Only Stations,''
which interpreted the 1992 I/M rule as further barring decentralized,
test-only stations from engaging in virtually all other for-profit
activities other than testing, prohibiting (for example) the sale of
convenience store type items. This prohibition was based upon the
further assumption that decentralized stations would otherwise use the
guarantee of a passing test as a way to attract customers to their
other sales and services.
In 1995, the substance of the Clean Air Act's enhanced I/M network
requirement was amended by implication by Section 348(b) of the
National Highway System Designation Act which specified that ``[t]he
Administrator shall not disapprove or apply an automatic discount to a
State implementation plan revision under section 182 or 187 of the
Clean Air Act (42 U.S.C. 7511a; 7512a) on the basis of a policy,
regulation, or guidance providing for a discount of emissions credits
because the inspection and maintenance program in such plan revision is
decentralized or a test-and-repair program.'' States opting for the
NHSDA's flexibility were allowed to claim prospective emission
reduction credit for their I/M SIPs based upon a ``good faith
estimate,'' and were to be granted an interim approval which would
lapse after 18 months if the credit claims were not substantiated by
way of a program effectiveness demonstration. While states were given a
limited time during which they could apply for interim approval under
the NHSDA (i.e., by March 28, 1996), the Highway Act's prohibition
against automatic, decentralized or test-and-repair discounts has no
such expiration date and therefore remains in effect permanently.
Today's proposal would amend the program network requirements at 40
CFR 51.353 in two ways:
First, the proposal would delete 40 CFR 51.353(b) which first
established the automatic credit discount for decentralized, test-and-
repair I/M programs. This amendment is proposed in recognition of and
compliance with the requirements of the National Highway System
Designation Act of 1995.
Second, the proposal would explicitly extend the definition of
decentralized test-only to allow such stations to engage in the full
range of sales not directly related to automotive parts sales or
service, including but not limited to the sale of self-serve gasoline,
pre-packaged oil, and other, non-automotive, convenience store items.
This proposal is based upon EPA's determination that a literal reading
of the 1992 I/M rule's definition does not support the broader
prohibitions set by the subsequent, 1994 policy. Such prohibitions have
been deemed irrelevant, post-NHSDA.
C. Test Procedure and Related Amendments
Section 182(c)(3)(C)(i) of the 1990 Clean Air Act established the
minimum requirements for enhanced I/M programs regarding test equipment
by stating that such programs must include ``(c)omputerized emission
analyzers, including on-road testing devices.'' The 1992 I/M rule, in
interpreting this requirement, was driven by the assumption that all
enhanced I/M programs would include IM240 tailpipe emission testing and
most (i.e., those required for ozone nonattainment or transport areas)
would also include evaporative system purge and pressure testing. As a
result, the 1992 I/M rule's requirements for test procedures and
standards at 40 CFR 51.357 and test equipment at 40 CFR 51.358 (as well
as other, related requirements throughout the 1992 I/M rule) tend to be
prescriptive to the point of excluding valid, alternative, non-IM240
test methodologies. This is especially the case since EPA promulgated
the I/M flexibility amendments in 1995 and 1996, and since passage of
the National Highway System Designation Act of 1995, which, taken
together, provided states the opportunity to explore a wide range of
alternative test type and network design combinations not
[[Page 45494]]
anticipated under the 1992 I/M rule. For example, it is currently
possible for some areas to design programs that meet the required
enhanced I/M performance standard without any tailpipe testing at all,
using, instead, a combination of alternative evaporative system
pressure testing methods, onboard diagnostic system checks, and visual
antitampering inspections. The problem is that the I/M rule, as
currently written, includes several provisions effecting test
procedures which assume tailpipe testing as a given, thus unnecessarily
discouraging areas from pursuing a design option which otherwise meets
the areas' needs and local conditions.
In response to the above dilemma, today's proposal would revise the
I/M rule in three areas:
First, the proposal would revise the test procedure and standard
requirements at 40 CFR 51.357 to clarify that tailpipe exhaust testing
is not a universal requirement for all I/M programs and that
alternatives to the IM240 drive cycle are allowed under the
requirements for transient testing. These revisions would be achieved
largely by deleting the words ``tailpipe'' and ``IM240,'' and inserting
the caveat ``where applicable,'' as needed. Similar amendments would be
made elsewhere in the regulatory text, to the extent that the existing
text creates the impression that IM240 or tailpipe testing are absolute
requirements, or that alternative test methods are otherwise barred.
The proposal would also clarify that the standard for an acceptable
alternative test is comparability, not necessarily equivalence.
Establishing ``equivalence'' as the standard for acceptability has the
effect of requiring that alternative tests individually get the same
level of reductions as the test being replaced. EPA believes that this
is an unnecessarily strict standard, and somewhat arbitrary if other
program parameters can be adjusted so the overall performance standard
is still met. That is, a slightly less effective test could still be
acceptable if performed more frequently or on a larger number of
vehicles to offset potential emission reduction losses due to the
alternative test's being comparable, but not strictly equivalent.
Second, the proposal would revise the test equipment requirements
at 40 CFR 51.358 to make the regulatory definition of ``computerized
analyzer'' less prescriptive to allow evaporative emission testing
devices and onboard diagnostic computer (OBD) scanners to qualify as
``computerized analyzers'' under the Act. The current regulatory
definition of ``computerized analyzers'' focuses on a system centered
on a traditional, personal computer, with keyboard input, etc. EPA
believes this is no longer appropriate under the Clean Air Act, given
the recent changes under the NHSDA discussed above. Under the broader
definition proposed, the focus would concentrate on the existence of a
central processing unit, and whether or not the criteria for making
pass/fail decisions are automated. EPA also proposes to relax the
requirement for a real-time data link for those areas required to do I/
M, but which do not need to claim I/M emission reductions to meet their
other, non-I/M CAA requirements. This is proposed to provide
flexibility to those areas which are not relying on I/M to meet their
CAA goals and that have opted to employ stand-alone test equipment that
is not readily connected to a centralized, real-time database. EPA
believes a real-time data link is not necessary for these types of
programs.
Third, the proposal would revise the data collection, analysis, and
reporting requirements at 40 CFR 51.365 and 40 CFR 51.366 to clarify
that the elements to be collected and reported are only required where
applicable to the program type in use in the area, and to make the
requirements less prescriptive with regard to the test types assumed.
These proposed revisions would also have the effect of streamlining
this portion of the rule and would likely reduce the paperwork burden
these reporting requirements place on states without compromising
overall program effectiveness.
D. Consumer Protection and Repair Effectiveness Amendments
Section 51.368(a) of the I/M rule currently requires that enhanced
I/M programs provide motorists that fail the inspection with
``software-generated, interpretive diagnostic information based on the
particular portions of the test that were failed.'' Section 51.369(c)
of the I/M rule requires that repair technicians receive training in
diagnostic theory related to transient and evaporative emission test
failures. In both cases, these requirements were developed based upon
the assumption that enhanced I/M programs would be built around the
IM240 test and would produce second-by-second emissions data that could
be used as an important diagnostic tool, with certain component
failures producing characteristic speed versus emission traces. Since
the 1992 rule was promulgated, however, a wide-range of non-transient,
alternative I/M tests have been approved for use in enhanced I/M
programs. These tests do not produce the detailed kind of diagnostic
information that is possible with a transient test like the IM240,
though they are certainly capable of producing generic diagnostic
information, based upon which tests and/or standards are failed.
Therefore, today's proposal would revise the diagnostic information
provisions at 40 CFR 51.368 and 40 CFR 51.369 to make the requirement
to provide diagnostic information more generic and only required where
applicable to the test type employed.
E. On-Road Testing Amendments
Section 182(c)(3)(C)(i) of the 1990 Clean Air Act requires that
enhanced I/M programs include ``on-road testing devices.'' In its 1992
I/M rule, EPA indicated that this requirement could be met by either
using remote sensing devices (RSD) or by conducting road-side pull-
over, tailpipe testing. In either case, vehicles which failed the test
were required to get out-of-cycle repairs, the presumption being that
the purpose of such testing was to identify dirty vehicles in need of
such repairs.
Today's proposal would revise the on-road testing requirements at
40 CFR 51.371 in two ways:
First, the proposal would remove language suggesting that the road-
side pull-over test must be a tailpipe test. The purpose of this change
is to open up this requirement so that it can be met using alternative
evaporative system pressure testing and/or OBD conducted at the
roadside, consistent with changes in I/M program design discussed
above.
Second, the proposal would remove the requirement for out-of-cycle
repairs where on-road testing is used as a pre-test clean screen
method. The purpose of this change is to allow states to use
alternative applications for RSD that have been developed since the
1992 I/M rule was promulgated. These alternatives include an approach
known as ``clean screening,'' where the goal is not to identify high
polluting vehicles for out-of-cycle repairs, but rather to identify
especially clean vehicles which can be exempted from the routine test.
Since such clean screening programs do not generate emission reductions
so much as run the risk of losing those reductions by falsely
identifying (and therefore exempting) vehicles needing repairs as
``clean,'' the proposal would also clarify that only on-road programs
requiring out-of-cycle repairs are eligible to claim additional
emission reduction credit for such pre-screening on-road testing.
[[Page 45495]]
V. Discussion of Major Issues
A. Emission Impact of the Proposed Amendments
Today's proposal introduces additional flexibilities which EPA
believes are needed to allow states to adopt and/or revise their I/M
programs in a way which helps them to meet local needs as smoothly as
possible. Today's proposal is also aimed at removing certain
restrictions in the 1992 I/M rule that would impede transition to the
I/M of the future, which EPA believes will focus largely on OBD-based
testing technologies available on 1996 and later model-year vehicles,
as opposed to today's traditional tailpipe tests. Although today's
proposal does have the potential for allowing some states to implement
more modest I/M programs than would otherwise be the case, nothing in
this notice should be construed as requiring or compelling states to
downsize their programs. Furthermore, nothing in this notice changes
the Clean Air Act's other requirements with regard to 15%, Reasonable
Further Progress, or Attainment plans. Instead, this proposal is aimed
at allowing states greater flexibility in deciding how to apportion the
emission reductions they need, reflecting local needs and conditions to
the best extent possible. In that regard, the intention of this
proposal is to take the focus off ``I/M for the sake of I/M'' and
return it where it belongs--on cleaning the air by whatever method
makes the most sense.
B. Impact on Existing and Future I/M Programs
Only states that choose to utilize the additional flexibilities
discussed in this notice will be affected by today's proposal to change
the I/M rule. Modifications to a state's I/M program as a result of
this rule change may require a SIP revision, if a plan has already been
submitted and approved. Each case is likely to be different, depending
upon the magnitude and direction of the change. It is important to note
that today's proposal in no way increases the existing burden on
states. States that currently comply, or are in the process of
complying, with the existing I/M rule would only be affected by today's
rule revisions if they so choose. Today's proposed amendments represent
options (not obligations or requirements) for those states that choose
to take advantage of the flexibilities proposed in today's notice.
Should a state with an approved I/M program for which credit is
being claimed as part of an approved Reasonable Further Progress (RFP)
and/or Attainment SIP choose to revise its I/M program in such a way as
to lower the emission reductions attributable to the I/M program, then
such state will need to not only revise its I/M SIP but also its
affected RFP and Attainment SIPs to address this shortfall.
Specifically, the emission reduction losses due to the state's changes
to its I/M program will have to be made up through the adoption and
implementation of additional measures which will need to be
incorporated as revisions to the affected RFP and Attainment SIPs. Such
revisions will be subject to notice-and-comment rulemaking, and must be
approved by the Administrator.
VI. Economic Costs and Benefits
Today's proposed revisions provide states additional flexibility
that lessens rather than increases the potential economic burden on
states. Furthermore, states are under no obligation, legal or
otherwise, to modify existing plans meeting the previously applicable
requirements as a result of today's proposal.
VII. Public Participation
EPA desires full public participation in arriving at final
decisions in this rulemaking action. EPA solicits comments on all
aspects of this proposal from all parties. Wherever applicable, full
supporting data and detailed analysis should also be submitted to allow
EPA to make maximum use of the comments. All comments should be
directed to the Air Docket, Docket No. A-99-19.
VIII. Administrative Requirements
A. Administrative Designation
It has been determined that these proposed amendments to the I/M
rule do not constitute a significant regulatory action under the terms
of Executive Order 12866 and this action is therefore not subject to
OMB review. Any impacts associated with these revisions do not
constitute additional burdens when compared to the existing I/M
requirements published in the Federal Register on November 5, 1992 (57
FR 52950) as amended. Nor does the proposed amendment create an annual
effect on the economy of $100 million or more or otherwise adversely
affect the economy or the environment. It is not inconsistent with nor
does it interfere with actions by other agencies. It does not alter
budgetary impacts of entitlements or other programs, and it does not
raise any new or unusual legal or policy issues.
B. Reporting and Recordkeeping Requirement
There are no additional information requirements in this
supplemental proposed rule which require the approval of the Office of
Management and Budget under the Paperwork Reduction Act 44 U.S.C. 3501
et seq.
C. Regulatory Flexibility Act
Pursuant to section 605(b) of the Regulatory Flexibility Act, 5
U.S.C. 605(b), the Administrator certifies that this proposal will not
have a significant economic impact on a substantial number of small
entities and, therefore, is not subject to the requirement of a
Regulatory Impact Analysis. A small entity may include a small
government entity or jurisdiction. This certification is based on the
fact that the I/M areas impacted by the proposed rulemaking do not meet
the definition of a small government jurisdiction, that is,
``governments of cities, counties, towns, townships, villages, school
districts, or special districts, with a population of less than
50,000.'' The basic and enhanced I/M requirements only apply to
urbanized areas with population in excess of either 100,000 or 200,000
depending on location. Furthermore, the impact created by the proposed
action does not increase the preexisting burden of the existing rules
which this proposal seeks to amend.
D. Unfunded Mandates Act
Under section 202 of the Unfunded Mandates Reform Act of 1995
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA
must prepare a budgetary impact statement to accompany any proposed or
final rule where the estimated costs to State, local, or tribal
governments, or to the private sector, will be $100 million or more.
Under Sec. 205, EPA must select the most cost-effective and least
burdensome alternative that achieves the objective of the rule and is
consistent with statutory requirements. Section 203 requires EPA to
establish a plan for informing and advising any small governments that
may be significantly impacted by the rule. To the extent that the rules
being proposed by this action would impose any mandate at all as
defined in Sec. 101 of the Unfunded Mandates Act upon the state, local,
or tribal governments, or the private sector, as explained above, this
proposed rule is not estimated to impose costs in excess of $100
million. Therefore, EPA has not prepared a statement with respect to
budgetary impacts. As noted above, this rule offers opportunities to
states that would enable them to lower economic burdens
[[Page 45496]]
from those resulting from the currently existing I/M rule.
E. Executive Order 12875: Enhancing the Intergovernmental Partnership
Under Executive Order 12875, EPA may not issue a regulation that is
not required by statute and that creates a mandate upon a State, local
or tribal government, unless the Federal government provides the funds
necessary to pay the direct compliance costs incurred by those
governments, or EPA consults with those governments. If EPA complies by
consulting, Executive Order 12875 requires EPA to provide to the Office
of Management and Budget a description of the extent of EPA's prior
consultation with representatives of affected State, local and tribal
governments, the nature of their concerns, any written communications
from the governments, and a statement supporting the need to issue the
regulation. In addition, Executive Order 12875 requires EPA to develop
an effective process permitting elected officials and other
representatives of State, local and tribal governments ``to provide
meaningful and timely input in the development of regulatory proposals
containing significant unfunded mandates. Today's rule does not create
a mandate on State, local or tribal governments. The rule does not
impose any enforceable duties on these entities. Accordingly, the
requirements of section 1(a) of Executive Order 12875 do not apply to
this rule.
F. Executive Order 13084: Consultation and Coordination With Indian
Tribal Governments
Under Executive Order 13084, EPA may not issue a regulation that is
not required by statute, that significantly or uniquely affects the
communities of Indian tribal governments, and that imposes substantial
direct compliance costs on those communities, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by the tribal governments, or EPA consults with those
governments. If EPA complies by consulting, Executive Order 13084
requires EPA to provide to the Office of Management and Budget, in a
separately identified section of the preamble to the rule, a
description of the extent of EPA's prior consultation with
representatives of affected tribal governments, a summary of the nature
of their concerns, and a statement supporting the need to issue the
regulation. In addition, Executive Order 13084 requires EPA to develop
an effective process permitting elected officials and other
representatives of Indian tribal governments ``to provide meaningful
and timely input in the development of regulatory policies on matters
that significantly or uniquely affect their communities.'' Today's rule
does not significantly or uniquely affect the communities of Indian
tribal governments. Today's rule does not create a mandate on tribal
governments or create any additional burden or requirements for tribal
government. The rule does not impose any enforceable duties on these
entities. Accordingly, the requirements of section 3(b) of Executive
Order 13084 do not apply to this rule.
G. 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 E.O. 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. EPA interprets E.O. 13045 as applying only to
those regulatory actions that are based on health or safety risks, such
that the analysis required under section 5-501 of the Order has the
potential to influence the regulation. This rule is not subject to E.O.
13045 because it is not economically significant under E.O. 12866 and
because it is based on technology performance and not on health or
safety risks.
H. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA) directs all Federal agencies to use voluntary
consensus standards instead of government-unique standards in their
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 and analytical procedures, business practices, etc.) that are
developed or adopted by one or more voluntary consensus standards
bodies. Examples of organizations generally regarded as voluntary
consensus standards bodies include the American Society for Testing and
Materials (ASTM), the National Fire Protection Association (NFPA), and
the Society of Automotive Engineers (SAE). The NTTAA requires Federal
agencies like EPA to provide Congress, through OMB, with explanations
when an agency decides not to use available and applicable voluntary
consensus standards.
These proposed amendments do not involve technical standards.
Therefore, EPA is not considering the use of any voluntary consensus
standards.

Dated: August 6, 1999.
Carol M. Browner,
Administrator.
For the reasons set out in the preamble, part 51 of title 40,
chapter I of the Code of Federal Regulations is proposed to be amended
to read as follows:
PART 51--[AMENDED]
1. The authority citation for part 51 is revised to read as
follows:
Authority: 23 U.S.C. 101; 42 U.S.C. 7401-7671q.
2. Section 51.350 is amended by revising paragraph (c) to read as
follows:
Sec. 51.350 Applicability.
* * * * *
(c) Requirements after attainment. All I/M programs shall provide
that the program will remain effective, even if the area is
redesignated to attainment status or the standard is otherwise rendered
no longer applicable, until the State submits and EPA approves a SIP
revision which convincingly demonstrates that the area can maintain the
relevant standard(s) without benefit of the emission reductions
attributable to the I/M program. The State shall commit to fully
implement and enforce the program until such a demonstration can be
made and approved by EPA. At a minimum, for the purposes of SIP
approval, legislation authorizing the program shall not sunset prior to
the attainment deadline for the applicable National Ambient Air Quality
Standards (NAAQS).
* * * * *
3. Section 51.351 is amended by removing and reserving paragraphs
(a), revisings (b), (f) introductory text, (f)(13), (g)(13) and (h)(11)
to read as follows:
[[Page 45497]]
Sec. 51.351 Enhanced I/M performance standard.
(a) [Reserved]
(b) On-road testing. The performance standard shall include on-road
testing (including out-of-cycle repairs in the case of confirmed
failures) of at least 0.5% of the subject vehicle population, or 20,000
vehicles whichever is less, as a supplement to the periodic inspection
required in paragraphs (f), (g), and (h) of this section. Specific
requirements are listed in Sec. 51.371 of this subpart.
* * * * *
(f) High Enhanced Performance Standard. Enhanced I/M programs shall
be designed and implemented to meet or exceed a minimum performance
standard, which is expressed as emission levels in area-wide average
grams per mile (gpm), achieved from highway mobile sources as a result
of the program. The emission levels achieved by the State's program
design shall be calculated using the most current version, at the time
of submittal, of the EPA mobile source emission factor model or an
alternative model approved by the Administrator, and shall meet the
minimum performance standard both in operation and for SIP approval.
Areas shall meet the performance standard for the pollutants which
cause them to be subject to enhanced I/M requirements. In the case of
ozone nonattainment areas subject to enhanced I/M and subject areas in
the Ozone Transport Region, the performance standard must be met for
both oxides of nitrogen (NOx) and volatile organic compounds (VOCs),
except as provided in paragraph (d) of this section. Except as provided
in paragraphs (g) and (h) of this section, the model program elements
for the enhanced I/M performance standard shall be as follows:
* * * * *
(13) Evaluation date. Enhanced I/M program areas subject to the
provisions of this paragraph shall be shown to obtain the same or lower
emission levels as the model program described in this paragraph by
January 1, 2002 to within +/-0.02 gpm. Subject programs shall
demonstrate through modeling the ability to maintain this level of
emission reduction (or better) through their attainment deadline for
the applicable NAAQS standard(s).
(g) * * *
(13) Evaluation date. Enhanced I/M program areas subject to the
provisions of this paragraph shall be shown to obtain the same or lower
emission levels as the model program described in this paragraph by
January 1, 2002 to within +/-0.02 gpm. Subject programs shall
demonstrate through modeling the ability to maintain this level of
emission reduction (or better) through their attainment deadline for
the applicable NAAQS standard(s).
(h) * * *
(11) Evaluation date. Enhanced I/M program areas subject to the
provisions of this paragraph shall be shown to obtain the same or lower
VOC and NOx emission levels as the model program described in this
paragraph by January 1, 2002 to within +/-0.02 gpm. Subject programs
shall demonstrate through modeling the ability to maintain this level
of emission reduction (or better) through their attainment deadline for
the applicable NAAQS standard(s). Equality of substituted emission
reductions to the benefits of the low enhanced performance standard
must be demonstrated for the same evaluation date.
4. Section 51.353 is amended by revising the introductory text and
paragraph (a) and by removing and reserving (b) to read as follows:
Sec. 51.353 Network type and program evaluation.
Basic and enhanced I/M programs can be centralized, decentralized,
or a hybrid of the two at the State's discretion, but shall be
demonstrated to achieve the same (or better) level of emission
reduction as the applicable performance standard described in either
Sec. 51.351 or Sec. 51.352 of this subpart. For decentralized programs
other than those meeting the design characteristics described in
paragraph (a) of this section, the State must demonstrate that the
program is achieving the level of effectiveness claimed in the plan
within 12 months of the plan's approval. The adequacy of these
demonstrations will be judged by the Administrator on a case-by-case
basis through notice-and-comment rulemaking.
(a) Presumptive equivalency. A decentralized network consisting of
stations that only perform official I/M testing (which may include
safety-related inspections) and in which owners and employees of those
stations, or companies owning those stations, are contractually or
legally barred from engaging in motor vehicle repair or service, motor
vehicle parts sales, and motor vehicle sale and leasing, either
directly or indirectly, and are barred from referring vehicle owners to
particular providers of motor vehicle repair services (except as
provided in Sec. 51.369(b)(1) of this subpart) shall be considered
presumptively equivalent to a centralized, test-only system including
comparable test elements. States may allow such stations to engage in
the full range of sales not covered by the above prohibition, including
self-serve gasoline, pre-packaged oil, or other, non-automotive,
convenience store items. At the State's discretion, such stations may
also fulfill other functions typically carried out by the State such as
renewal of vehicle registration and driver's licenses, or tax and fee
collections. Decentralized networks designed around these restrictions
need not provide any additional demonstration to substantiate their I/M
SIP emission reduction credit claims, with the exception of the
biennial program evaluation required of all enhanced I/M programs and
described in paragraph (c) of this section.
(b) [Reserved]
* * * * *
5. Section 51.357 is amended by revising paragraphs (a)(3), (a)(4),
(a)(6), (a)(11), and (a)(13) to read as follows:
Sec. 51.357 Test procedures and standards.
* * * * *
(a) * * *
(3) An official test, once initiated, shall be performed in its
entirety regardless of intermediate outcomes except in the case of
invalid test condition, unsafe conditions, fast pass/fail algorithms,
or, in the case of the on-board diagnostic (OBD) system check, unset
readiness codes.
(4) Tests involving measurement shall be performed with program-
approved equipment that has been calibrated according to the quality
procedures contained in appendix A to this subpart.
* * * * *
(6) Vehicles shall be retested after repair for any portion of the
inspection that is failed on the previous test to determine if repairs
were effective. To the extent that repair to correct a previous failure
could lead to failure of another portion of the test, that portion
shall also be retested. Evaporative system repairs shall trigger an
exhaust emissions retest (in programs which conduct an exhaust emission
test as part of the initial inspection).
* * * * *
(11) Transient emission test. The transient emission test shall
consist of mass emission measurement using a constant volume sampler
(or an Administrator-approved alternative methodology for accounting
for exhaust volume) while the vehicle is driven through a computer-
monitored driving cycle on a dynamometer. The driving cycle shall
include acceleration, deceleration, and idle operating modes as
specified in appendix E to this subpart (or an approved alternative).
[[Page 45498]]
The driving cycle may be ended earlier using approved fast pass or fast
fail algorithms and multiple pass/fail algorithms may be used during
the test cycle to eliminate false failures. The transient test
procedure, including algorithms and other procedural details, shall be
approved by the Administrator prior to use in an I/M program.
* * * * *
(13) Approval of alternative tests. Alternative test procedures may
be approved if the Administrator finds that such procedures would
produce comparable emission reductions from the I/M program as a whole,
in combination with other program elements.
* * * * *
6. Section 51.358 is amended by revising the introductory text,
paragraphs (a) introductory text, (a)(2)(i), (a)(2)(ii), (a)(2)(iv),
(a)(3) introductory text, (a)(3)(iv), (a)(3)(vi), (a)(3)(ix), (b)
introductory text, (b)(2) and (c) and by removing and reserving (b)(1)
and (3) to read as follows:
Sec. 51.358 Test equipment.
Computerized test systems are required for performing an official
emissions test on subject vehicles.
(a) Performance features of computerized test systems. With the
exception of test procedures relying upon a vehicle's onboard
diagnostic (OBD) system (which is certified as part of the overall
vehicle certification process), the test equipment shall be certified
by the program, and newly acquired systems shall be subjected to
acceptance test procedures to ensure compliance with program
specifications.
(2) * * *
(i) Shall be automated;
(ii) Shall be secured from tampering and/or abuse;
(iii) * * *
(iv) Shall be capable of simultaneously sampling dual exhaust
vehicles in the case of tailpipe-based emission test equipment.
(3) The vehicle owner or driver shall be provided with a record of
test results, including all of the items listed in 40 CFR part 85,
subpart W as being required on the test record (as applicable). The
test report shall include:
* * * * *
(iv) The type(s) of test(s) performed;
* * * * *
(vi) The test results, by test, and, where applicable, by
pollutant;
* * * * *
(ix) For vehicles that fail the emission test, information on the
possible cause(s) of the failure.
(b) Functional characteristics of computerized test systems. The
test system is composed of motor vehicle test equipment controlled by a
computerized processor and shall make automatic pass/fail decisions.
(1) [Reserved]
(2) Test systems in enhanced I/M programs shall include a real-time
data link to a host computer that prevents unauthorized multiple
initial tests on the same vehicle in a test cycle and to insure test
record accuracy. For areas which have demonstrated the ability to meet
their other, non-I/M Clean Air Act requirements without relying on
emission reductions from the I/M program (and which have also elected
to employ stand-alone test equipment as part of the I/M program), such
areas may adopt alternative methods for preventing multiple initial
tests, subject to approval by the Administrator.
(3) [Reserved]
* * * * *
(c) SIP requirements. The SIP shall include written technical
specifications for all test equipment used in the program and shall
address each of the above requirements (as applicable). The
specifications shall describe the testing process, the necessary test
equipment, the required features, and written acceptance testing
criteria and procedures.
7. Section 51.359 is amended by revising the introductory text, and
paragraph (a)(1), removing and reserving (a)(3) and revising (c) and
(d) to read as follows:
Sec. 51.359 Quality control.
Quality control measures shall insure that emission testing
equipment is calibrated and maintained properly, and that inspection,
calibration records, and control charts are accurately created,
recorded and maintained (where applicable).
(a) * * * (1) The practices described in this section and in
appendix A to this subpart shall be followed for those tests (or
portions of tests) which fall into the testing categories identified.
Alternatives or exceptions to these procedures or frequencies may be
approved by the Administrator based on a demonstration of comparable
performance.
(2) * * *
(3) [Reserved]
* * * * *
(c) Requirements for transient exhaust emission test equipment.
Equipment shall be maintained according to demonstrated good
engineering practices to assure test accuracy. Computer control of
quality assurance checks and quality control charts shall be used
whenever possible. Exceptions to the procedures and the frequency of
the checks described in appendix A of this subpart may be approved by
the Administrator based on a demonstration of comparable performance.
(d) Requirements for evaporative system functional test equipment.
Equipment shall be maintained according to demonstrated good
engineering practices to assure test accuracy. Computer control of
quality assurance checks and quality control charts shall be used
whenever possible. Exceptions to the procedures and the frequency of
the checks described in appendix A of this subpart may be approved by
the Administrator based on a demonstration of comparable performance.
* * * * *
8. Section 51.362 is amended by revising paragraphs (a)(2) and
(b)(4) to read as follows:
Sec. 51.362 Motorist compliance enforcement program oversight.
* * * * *
(a) * * *
(2) Facilitation of accurate critical test data and vehicle
identifier collection through the use of automatic data capture systems
such as bar-code scanners or optical character readers, or through
redundant data entry (where applicable);
* * * * *
(b) * * *
(4) Maintain and ensure the accuracy of the testing database
through periodic internal and/or third-party review;
* * * * *
9. Section 51.363 is amended by revising paragraphs (a)(4)(vii),
(b)(1), (c)(10), (d)(1)(i) to read as follows:
Sec. 51.363 Quality assurance.
* * * * *

paragraphs (a)(3), (a)(23), (a)(24), (a)(25), and (b) to read as
follows:
Sec. 51.365 Data collection.
Accurate data collection is essential to the management,
evaluation, and enforcement of an I/M program. The program shall gather
test data on individual vehicles, as well as quality control data on
test equipment (with the exception of test procedures for which either
no testing equipment is required or those test procedures relying upon
a vehicle's OBD system).
(a) * * *
(3) Test system number (where applicable);
* * * * *
(23) Results of the evaporative system pressure test(s) expressed
as a pass or fail;
(24) Results of the evaporative system purge test expressed as a
pass or fail along with the total purge flow in liters achieved during
the test (where applicable); and
(25) Results of the on-board diagnostic check expressed as a pass
or fail along with the diagnostic trouble codes revealed (where
applicable).
(b) Quality control data. At a minimum, the program shall gather
and report the results of the quality control checks required under
Sec. 51.359 of this subpart, identifying each check by station number,
system number, date, and start time. The data report shall also contain
the concentration values of the calibration gases used to perform the
gas characterization portion of the quality control checks (where
applicable).
11. Section 51.366 is amended by revising paragraphs (a)(2)(i),
(a)(2)(ii), (a)(2)(iii), (a)(2)(iv), (a)(2)(v), (a)(2)(vi), (b)(3)(i),
(b)(3)(ii), (b)(3)(iii) and (b)(3)(iv) to read as follows:

(3) In order to complete the training requirement, a trainee shall
pass (i.e., a minimum of 80% of correct responses or lower if an
occupational analysis justifies it) a written test covering all aspects
of the training. In addition, a hands-on test shall be administered in
which the trainee demonstrates without assistance the ability to
conduct a proper inspection and to follow other required procedures.
Inability to properly conduct all test procedures shall constitute
failure of the test. The program shall take appropriate steps to insure
the security and integrity of the testing process.
* * * * *
13. Section 51.368 is amended by revising paragraph (a) to read as
follows:
Sec. 51.368 Public information and consumer protection.
(a) Public awareness. The SIP shall include a plan for informing
the public on an ongoing basis throughout the life of the I/M program
of the air quality problem, the requirements of Federal and State law,
the role of motor vehicles in the air quality problem, the need for and
benefits of an inspection program, how to maintain a vehicle in a low-
emission condition, how to find a qualified repair technician, and the
requirements of the I/M program. Motorists that fail the I/M test in
enhanced I/M areas shall be offered a list of repair facilities in the
area and information on the results of repairs performed by repair
facilities in the area, as described in Sec. 51.369(b)(1) of this
subpart. Motorists that fail the I/M test shall also be provided with
information concerning the possible cause(s) for failing the particular
portions of the test that were failed.
* * * * *
14. Section 51.369 is amended by revising paragraphs (c)(2) and
(c)(3) to read as follows:
Sec. 51.369 Improving repair effectiveness.
* * * * *
(c) * * *

failures observed in the transient emission test and the evaporative
system functional checks (where applicable); and
* * * * *
15. Section 51.371 is amended by revising the introductory text,
paragraphs (a)(2), (a)(3), (b)(2) and (b)(3) to read as follows:
Sec. 51.371 On-road testing.
On-road testing is defined as testing of vehicles for conditions
directly impacting the emission of HC, CO, NOX and/or
CO<INF>2</INF> emissions on any road or roadside in the nonattainment
area or the I/M program area. On-road testing is required in enhanced
I/M areas and is an option for basic I/M areas.
(a) * * *
(2) On-road testing is not required in every season or on every
vehicle but shall evaluate the emission performance of 0.5% of the
subject fleet statewide or 20,000 vehicles, whichever is less, per
inspection cycle.
(3) The on-road testing program shall provide information about the
performance of in-use vehicles, by measuring on-road emissions through
the use of remote sensing devices or by assessing vehicle emission
performance through roadside pullovers including onboard diagnostic
(OBD) system testing or other emission testing. The program shall
collect, analyze and report on-road testing data.
* * * * *
(b) * * *
(2) The SIP shall include the legal authority necessary to
implement the on-road testing program, including the authority to
enforce off-cycle inspection and repair requirements (where
applicable).
(3) Emission reduction credit for on-road testing programs shall be
granted for a program designed to obtain significant emission
reductions over and
[[Page 45500]]
above those already predicted to be achieved by other aspects of the I/
M program. Emission reduction credit will only be granted to those
programs which require out-of-cycle repairs for confirmed high-emitting
vehicles identified under the on-road testing program. The SIP shall
include technical support for the claimed additional emission
reductions.
