Transportation Conformity Rule: MOVES Regional Grace Period
Extension
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to extend the grace period before the MOtor
Vehicle Emission Simulator model (currently MOVES2010a) is required for
regional emissions analyses for transportation conformity
determinations (``regional conformity analyses''). This proposal would
provide an additional year to the previously established two-year
conformity grace period, so that MOVES2010a would not be required for
regional conformity analyses until March 2, 2013. This proposal would
not affect EPA's previous approval of the use of MOVES in official
state air quality implementation plan (SIP) submissions or the existing
grace period before MOVES2010a is required for carbon monoxide and
particulate matter hot-spot analyses for project-level conformity
determinations.
DATES: Written comments on this proposal must be received on or before
November 14, 2011.

II. Background
A. What is transportation conformity?
Transportation conformity is required under Clean Air Act (CAA)
section 176(c) (42 U.S.C. 7506(c)) to ensure that transportation plans,
transportation improvement programs (TIPs), and federally supported
highway and transit projects are consistent with the purpose of the
SIP. Conformity to the purpose of the SIP means that transportation
activities will not cause or contribute to new air quality violations,
worsen existing violations, or delay timely attainment of the relevant
national ambient air quality standard (NAAQS) or required interim
milestones.
Transportation conformity (hereafter, ``conformity'') applies to
areas that are designated nonattainment, and those areas redesignated
to attainment after 1990 (``maintenance areas'') for transportation-
related criteria pollutants: Ozone, particulate matter
(PM2.5 and PM10) \1\, carbon monoxide (CO), and
nitrogen dioxide (NO2). EPA's conformity rule (40 CFR Parts
51 and 93) establishes the criteria and procedures for determining
whether transportation activities conform to the SIP. EPA first
promulgated the conformity rule on November 24, 1993 (58 FR 62188) and
subsequently published several other amendments. The Department of
Transportation (DOT) is EPA's federal partner in implementing the
conformity regulation. EPA has coordinated with DOT, and they concur
with this proposal.
---------------------------------------------------------------------------
\1\ 40 CFR 93.102(b)(1) defines PM2.5 and
PM10 as particles with an aerodynamic diameter less than
or equal to a nominal 2.5 and 10 micrometers, respectively.
---------------------------------------------------------------------------
B. What is MOVES2010a, and how has it been implemented to date?
The MOtor Vehicle Emission Simulator model (MOVES) is EPA's state-
of-the-art model for estimating emissions from highway vehicles, based
on analyses of millions of emission test results and considerable
advances in the Agency's understanding of vehicle emissions. MOVES is
currently EPA's official emissions model for state and local agencies
to estimate volatile organic compounds (VOCs), nitrogen oxides
(NOX), PM, CO, and other precursors from cars, trucks,
buses, and motorcycles for SIP purposes and conformity determinations
outside of California. MOVES' database-centered design allows EPA to
update emissions data more frequently and allows users much greater
flexibility in organizing input and output data.
MOVES2010a is the latest official version of MOVES that EPA has
approved for SIP and conformity purposes. EPA originally announced the
release of MOVES2010 in the Federal Register on March 2, 2010 (75 FR
9411) and subsequently released MOVES2010a on September 8, 2010.
MOVES2010a includes minor revisions that enhance model performance and
did not significantly affect criteria pollutant emissions results.
Since these are minor revisions to MOVES2010, MOVES2010a is not
considered a ``new model'' under section 93.111 of the conformity rule,
as described further below.
MOVES2010a is a significant improvement over the previous emissions
model, MOBILE6.2,\2\ in terms of quality of results and overall
functionality. It incorporates the latest emissions data, more
sophisticated calculation algorithms, increased user flexibility, new
software design, and significant new capabilities. While these changes
improve the quality of on-road mobile source inventories, the overall
degree of change in the model's function also adds to the start-up time
required for the transition from MOBILE6.2 to MOVES2010a.
---------------------------------------------------------------------------
\2\ EPA announced the release of MOBILE6.2 in 2004 (69 FR
28830).
---------------------------------------------------------------------------
EPA developed MOVES as a completely new model. Whereas MOBILE6.2
was written in FORTRAN and used simple text files for data input and
output, MOVES2010a is written in JAVA and uses a relational database
structure in MYSQL to handle input and output as data tables. These
changes make MOVES more flexible, and the analysis of new data
incorporated within MOVES will enhance state and local agency
understanding of how on-road mobile sources contribute to emissions
inventories and the relative effectiveness of various control
strategies. However, this new model framework has created a significant
learning curve for state and local agency staff that are required to
use MOVES.\3\
---------------------------------------------------------------------------
\3\ Some states also purchased computers with additional
capacity and features for running MOVES.
---------------------------------------------------------------------------
In addition to the challenges of learning new software, state and
local agencies also have to make substantial changes in the processes
they have developed to create model input and apply model output. While
there were incremental changes between each previous version of the
MOBILE model, the basic input and output structure of that model was
essentially unchanged since the early 1980s. Over time, state and local
agencies developed their own methods for incorporating local inputs in
MOBILE format and for post-processing MOBILE results for inventory
development and air quality modeling. To help state and local agencies
with this part of the current transition, EPA created a number of tools
that take input data formatted for MOBILE6.2 and convert that data for
use in MOVES2010a.
EPA anticipated many of these challenges when it released MOVES. In
order to assist in this model transition, EPA and DOT have already
provided hands-on MOVES training in many states.\4\ Additional MOVES
training for regional inventories has been requested, and will continue
to be offered for the foreseeable future. EPA continues to provide
other technical assistance to state and local agencies via on-going
conference calls with user groups, e-mail and phone support, a
frequently asked questions web page, and web-based presentations. All
of these efforts are helping state and local agencies make the
transition to MOVES2010a, and many agencies are making significant
progress in applying the model for official purposes. However, other
state and local agencies are still developing the technical capacity to
use MOVES2010a, and need more time to transition to the model and then
evaluate whether SIPs and their motor vehicle emissions budgets, or
transportation plans and TIPs, should be
[[Page 63578]]
revised for future conformity determinations.
---------------------------------------------------------------------------
\4\ To date, EPA and DOT staff have provided a 2-day hands-on
MOVES course for regional emissions inventories (including regional
conformity analyses) at over 30 locations around the country.
---------------------------------------------------------------------------
C. Why is EPA conducting this rulemaking?
If finalized, today's action would provide additional time that may
be critical for nonattainment and maintenance areas to learn and apply
MOVES2010a for regional conformity analyses.\5\ EPA has been contacted
by several state and local transportation and air quality agencies and
associations that are concerned that there has not been sufficient
transition time for using MOVES2010a in regional conformity analyses.
These concerns revolve around the time needed to build technical
capacity for using MOVES2010a as well as completing necessary SIP and/
or transportation plan/TIP changes to assure conformity in the future.
Further details on today's action are provided below.
---------------------------------------------------------------------------
\5\ MPOs conduct regional conformity analyses to demonstrate
that transportation plans and TIPs are consistent with the air
quality purposes of the SIP. Regional conformity analyses are also
conducted in ``isolated rural nonattainment and maintenance areas''
(defined by 40 CFR 93.101).
---------------------------------------------------------------------------
Today's proposal would not affect EPA's previous approval of
MOVES2010a for official SIP submissions developed outside of
California.\6\ Today's rulemaking would also not affect the existing
grace period before MOVES2010a is required for PM2.5,
PM10, and CO hot-spot analyses for project-level conformity
determinations (75 FR 79370). EPA coordinated closely with DOT in
developing today's action, and DOT concurs on this proposed rule.
---------------------------------------------------------------------------
\6\ MOVES is not approved for use in California. EPA approved
and announced the latest version of California's EMFAC model
(EMFAC2007) for SIP development and regional conformity analyses in
that state on January 18, 2008 (73 FR 3464).
---------------------------------------------------------------------------
III. Extension of MOVES2010a Regional Conformity Grace Period
A. Background
CAA section 176(c)(1) states that ``* * * [t]he determination of
conformity shall be based on the most recent estimates of emissions,
and such estimates shall be determined from the most recent population,
employment, travel, and congestion estimates * * *.'' To meet this
requirement, section 93.111 of the conformity rule requires that
conformity determinations be based on the latest motor vehicle
emissions model approved by EPA. When EPA approves a new emissions
model, EPA consults with DOT to establish a grace period before the
model is required for conformity analyses (40 CFR 93.111(b)). EPA must
consider many factors when establishing a grace period for conformity
determinations (40 CFR 93.111(b)(2)). The length of the grace period
will depend on the degree of change in the model and the scope of re-
planning likely to be necessary for MPOs in order to assure conformity.
The conformity rule provides for a grace period for new emissions
models of between three and 24 months (40 CFR 93.111(b)(1)).
In the preamble to the original 1993 conformity rule, EPA
articulated its intentions for establishing the length of conformity
grace period for a new emissions model (58 FR 62211):
``EPA and DOT will consider extending the grace period if the
effects of the new emissions model are so significant that previous
SIP demonstrations of what emission levels are consistent with
attainment would be substantially affected. In such cases, states
should have an opportunity to revise their SIPs before MPOs must use
the model's new emissions factors. EPA encourages all agencies to
inform EPA of the impacts of new emissions models in their area, and
EPA may pause to seek such input before determining the length of
the grace period.''
Section 93.111 conformity requirements have not changed since 1993, and
have been implemented successfully for many previous model transitions.
On March 2, 2010, EPA announced the official release of MOVES2010
and established a two-year grace period before this model was required
for new regional conformity analyses (75 FR 9411). Although the
original grace period was established for MOVES2010, EPA clarified in
September 2010 that the same grace period for regional conformity
analyses also applies to MOVES2010a.\7\ EPA based its decision to
establish a two-year conformity grace period on the factors under
section 93.111(b)(2), and advised areas to use the interagency
consultation process to examine the impact of using MOVES in their
future regional conformity analyses.
---------------------------------------------------------------------------
\7\ See ``EPA Releases MOVES2010a Mobile Source Emissions Model
Update: Questions and Answers'' (EPA-420-F-10-050, August 2010) at:
http://www.epa.gov/otaq/models/moves/MOVES2010a/420f10050.pdf.
---------------------------------------------------------------------------
Without further EPA action, MOVES2010a would be required for
regional conformity analyses that begin after March 2, 2012. As
discussed further in today's action, the special circumstances of the
transition from MOBILE to MOVES2010a require a reevaluation of the
length of this conformity grace period.
B. Description of Proposed Rule
In today's action, EPA is proposing to provide an additional year
before MOVES2010a is required for regional conformity analyses. If
finalized, MOVES2010a would be required for new regional conformity
analyses that begin after March 2, 2013. State and local agencies
outside California would use MOVES2010a for regional conformity
analyses earlier than March 2, 2013, if desired, and would be required
to do so under limited circumstances such as after MOVES2010a SIP motor
vehicle emissions budgets have been found adequate or approved for
conformity purposes.
Due to the unique circumstances presented by the transition from
MOBILE6.2 to MOVES2010a, EPA is proposing to add a new paragraph (b)(3)
to section 93.111 of the conformity rule. This provision would only
apply to MOVES2010a and any future minor revisions to this model that
EPA releases before March 2, 2013. Such minor revisions would not start
a new grace period for regional conformity analyses and could include
performance enhancements that reduce MOVES run time or model
improvements to reduce errors in operating the model. Any major model
updates, such as an update that significantly changes MOVES results for
criteria pollutant emissions, would be evaluated separately as a ``new
model'' under conformity rule section 93.111, pursuant to previously
established requirements.
Before the end of the extended conformity grace period (March 2,
2013), areas would use the interagency consultation process to examine
how MOVES2010a would impact their future MPO transportation plan/TIP
conformity determinations. Isolated rural areas would also consider the
impact of using MOVES2010a on future regional conformity analyses. If
finalized, agencies should carefully consider whether the SIP and its
motor vehicle emissions budgets should be revised with MOVES2010a or if
transportation plans and TIPs should be revised before the end of the
conformity grace period, since doing so may be necessary to ensure
conformity in the future.
The proposal would allow regional conformity analyses that are
started during the grace period to be based on either MOBILE6.2 or
MOVES2010a. If the grace period ended on March 2, 2013, MOVES2010a
would become the only approved motor vehicle emissions model for
regional conformity analyses outside California at that time. This
would mean that all new regional conformity analyses started after the
end of the grace period must be based on MOVES2010a, even if the SIP is
based
[[Page 63579]]
on MOBILE6.2 or earlier versions of MOBILE.
For complete explanations of how MOVES2010a is to be implemented
for transportation conformity, including details about using MOVES2010a
during the grace period, refer to EPA's existing MOVES policy
guidance.\8\
---------------------------------------------------------------------------
\8\ ``Policy Guidance on the Use of MOVES2010 for State
Implementation Plan Development, Transportation Conformity, and
Other Purposes'' (EPA-420-B-09-046, December 2009) can be found on
the EPA's transportation conformity Web site at: http://www.epa.gov/otaq/stateresources/transconf/policy.htm.
---------------------------------------------------------------------------
C. Rationale
MOVES2010a is EPA's best tool for estimating criteria pollutant
emissions, and it is a significant improvement over previous MOBILE
models. State and local agencies have made significant progress to date
in using MOVES2010a, and EPA supports these efforts and encourages that
they continue. However, as discussed above, challenges related to
start-up and model application have been much greater in the transition
to MOVES2010a, compared to past transitions between MOBILE model
versions. As a result, EPA has determined that a one-year extension of
the MOVES2010a grace period is necessary for state and local agencies
to complete the current transition. Today's action would ensure that
state and local governments have the necessary time to implement the
conformity rule as originally intended.
Since 1993, the fundamental purpose of section 93.111(b) of the
conformity rule has been to provide a sufficient amount of time for
MPOs and other state and local agencies to adapt to using new emissions
tools. As discussed above, the transition to a new emissions model for
conformity involves more than learning to use the new model and
preparing input data and model output. After model start-up is
complete, state and local agencies also need to consider how the model
affects regional conformity analysis results and whether SIP and/or
transportation plan/TIP changes are necessary to assure future
conformity determinations. EPA believes that the proposed one-time
extension of the current MOVES2010a regional grace period is critical
to assure future conformity determinations based on MOVES2010a.
EPA has the discretion to establish an extended grace period for
MOVES2010a, and today's action is consistent with CAA section 176(c)(1)
requirements. EPA believes that the proposal to provide one additional
year is appropriate due to this unique transition from MOBILE6.2 to
MOVES2010a. This decision is consistent with the existing conformity
criteria in section 93.111(b)(2) of the conformity rule that requires
the length of the grace period to be based on ``the degree of change in
the model and the scope of re-planning likely to be necessary by MPOs
in order to assure conformity.''
Today's proposal would not delay the use of MOVES2010a in SIP
development or slow down past progress toward using the new model for
regional conformity analyses. As noted above, many state and local
agencies are already learning and applying MOVES2010a. Some are
revising existing SIP budgets using the new model, while others may be
incorporating MOVES2010a into new maintenance plans or clean data
determinations. Under EPA's existing MOVES policy guidance, new or
revised SIP budgets must still be based on MOVES2010a. For example,
MOVES2010a continues to be required for attainment SIPs for the 2006
24-hour PM2.5 NAAQS. Under the proposal, MOVES2010a would
also be required for any regional conformity analyses prior to March 2,
2013 if SIP budgets based on MOVES2010 or MOVES2010a are approved or
found adequate sooner.\9\
---------------------------------------------------------------------------
\9\ See Questions 5, 6, and 11 of ``Policy Guidance on the Use
of MOVES2010 for State Implementation Plan Development,
Transportation Conformity, and Other Purposes'' (EPA-420-B-09-046,
December 2009).
---------------------------------------------------------------------------
In addition, today's action would not change the current MOVES2010a
grace period for new PM2.5, PM10, and CO hot-spot
analyses for project-level conformity determinations. EPA noted
previously that a two-year conformity grace period was necessary to
apply MOVES2010a for hot-spot analyses (75 FR 79370). However, the
transition to MOVES2010a for project-level hot-spot analyses does not
involve the complexity associated with the regional level, where SIP
budgets and/or transportation plans/TIPs may need to be revised before
regional conformity analyses based on MOVES2010a can be completed.
Finally, in issuing this proposal, EPA is not proposing to proceed
pursuant to or reopen as a general matter the process and length of
conformity grace periods for future emissions model approvals, which
were previously established in 1993 (58 FR 62211). The unique set of
circumstances involved in the current transition warrants the proposed
additional state and local flexibility before MOVES2010a is required
for regional conformity analyses.
IV. Conformity SIPs
The proposed MOVES2010a regional grace period extension would apply
on the effective date of a final rule in all nonattainment and
maintenance areas. Section 51.390(a) of the conformity rule states that
the federal rule applies for the portion of the requirements that are
not included in a state's approved conformity SIP.\10\ Section
51.390(b) further allows state conformity provisions to contain
criteria and procedures that are more stringent than the federal
requirements. However, in the case of states with conformity SIPs that
include the grace period provision in 40 CFR 93.111(b)(1), EPA
concludes that such states did not intend to require a shorter grace
period than EPA, in consultation with DOT, believes is needed.
Therefore, since the MOVES2010a grace period extension would be a new
provision being added to the conformity rule, it is not included in any
current state conformity SIP and therefore would apply immediately, if
finalized, in all areas pursuant to section 51.390(a).
---------------------------------------------------------------------------
\10\ A conformity SIP is required by the CAA and contains a
state's conformity requirements, including the state's specific
interagency consultation procedures.
---------------------------------------------------------------------------
In addition, section 51.390(c) of the conformity rule requires
states to submit a new or revised conformity SIP to EPA within 12
months of the Federal Register publication date of final conformity
rules in certain situations. States with approved conformity SIPs that
are prepared in accordance with current CAA requirements would not be
required to submit new conformity SIP revisions under a final rule,
since section 93.111 of the conformity rule is not contained in these
SIPs. A conformity SIP prepared in accordance with current CAA
requirements contains only the state's criteria and procedures for
interagency consultation (40 CFR 93.105) and two additional provisions
related to written commitments for certain control and mitigation
measures (40 CFR 93.122(a)(4)(ii) and 93.125(c)). However, states with
approved conformity SIPs that include section 93.111 from a previous
rulemaking would be required to submit a SIP revision within 12 months
of the publication date of any final rule, although EPA strongly
encourages these states to submit a SIP revision with only the three
required provisions.\11\ A state without an approved conformity SIP
would not be required to submit a new conformity SIP
[[Page 63580]]
within one year of a final rule, but previous conformity SIP deadlines
continue to apply.
---------------------------------------------------------------------------
\11\ The conformity SIP may contain provisions more stringent
than the federal requirements, and in these cases, states would
specify this intention in its original conformity SIP submission.
---------------------------------------------------------------------------
For additional information on conformity SIPs, please refer to the
January 2009 guidance entitled, ``Guidance for Developing
Transportation Conformity State Implementation Plans'' available on
EPA's Web site at: http://www.epa.gov/otaq/stateresources/transconf/policy/420b09001.pdf.
V. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is a ``significant regulatory action.'' Accordingly, EPA
submitted this action to the Office of Management and Budget (OMB) for
review under Executive Orders 12866 and 13563 (76 FR 3821, January 21,
2011) and any changes made in response to OMB recommendations have been
documented in the docket for this action.
B. Paperwork Reduction Act
This action would not impose any new information collection burden.
The information collection requirements of EPA's existing
transportation conformity regulations and the proposed revisions in
today's action are already covered by EPA information collection
request (ICR) entitled, ``Transportation Conformity Determinations for
Federally Funded and Approved Transportation Plans, Programs and
Projects.'' OMB has previously approved the information collection
requirements contained in the existing regulations at 40 CFR Part 93
under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et
seq. and has assigned OMB control number 2060-0561. The OMB control
numbers for EPA's regulations in 40 CFR are listed in 40 CFR Part 9.
C. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA) generally requires an Agency
to prepare a regulatory flexibility analysis of rules 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 not-for-profit organizations and small government jurisdictions.
For purposes of assessing the impacts of today's proposal on small
entities, small entity is defined as: (1) A small business as defined
by the Small Business Administration's (SBA) regulations at 13 CFR
121.201; (2) a small governmental jurisdiction that is a government of
a city, county, town, school district or special district with a
population of less than 50,000; and (3) a small organization that is
any not-for-profit enterprise that is independently owned and operated
and is not dominant in its field.
After considering the economic impacts of today's proposed rule on
small entities, I certify that this action would not have a significant
economic impact on a substantial number of small entities. This
proposal would directly affect federal agencies and MPOs that, by
definition, are designated under federal transportation laws only for
metropolitan areas with a population of at least 50,000. These
organizations do not constitute small entities within the meaning of
the RFA. Therefore, this proposal would not impose any requirements on
small entities.
D. Unfunded Mandates Reform Act (UMRA)
This proposal does not contain a Federal mandate that may result in
expenditures of $100 million or more for state, local, and tribal
governments, in the aggregate, or the private sector in any one year.
This rule would merely implement already established law that imposes
conformity requirements and would not itself impose requirements that
may result in expenditures of $100 million or more in any year. Thus,
today's proposal is not subject to the requirements of sections 202 and
205 of the UMRA.
This proposal is also not subject to the requirements of section
203 of UMRA because it contains no regulatory requirements that might
significantly or uniquely affect small governments. This proposal would
not significantly or uniquely impact small governments because it
directly affects federal agencies and MPOs that, by definition, are
designated under federal transportation laws only for metropolitan
areas with a population of at least 50,000.
E. Executive Order 13132: Federalism
This proposal does not have federalism implications. It would not
have substantial direct effects on states, on the relationship between
the national government and states, or on the distribution of power and
responsibilities among the various levels of government, as specified
in Executive Order 13132. The CAA requires conformity to apply in
certain nonattainment and maintenance areas as a matter of law, and
today's action would merely revise one provision for transportation
planning entities in subject areas to follow in meeting their existing
statutory obligations. Thus, Executive Order 13132 does not apply to
this proposal.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications, as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000). The CAA requires
transportation conformity to apply in any area that is designated
nonattainment or maintenance by EPA. Because today's proposal would not
significantly or uniquely affect the communities of Indian tribal
governments, Executive Order 13175 does not apply to this action.
G. Executive Order 13045: Protection of Children From Environmental
Health and Safety Risks
This proposal is not subject to Executive Order 13045 (62 FR 19885,
April 23, 1997) because it is not economically significant as defined
in Executive Order 12866, and because the Agency does not believe the
environmental health or safety risks addressed by this action present a
disproportionate risk to children.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This proposal is not a ``significant energy action'' as defined in
Executive Order 13211 (66 FR 18355 (May 22, 2001)), because it is not
likely to have a significant adverse effect on the supply,
distribution, or use of energy. It would not create a serious
inconsistency or otherwise interfere with an action taken or planned by
another agency regarding energy. This action is not subject to
Executive Order 13211 because it does not have any adverse energy
effects.
I. National Technology Transfer and Advancement Act
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,
[[Page 63581]]
sampling procedures, and business practices) that are developed or
adopted by voluntary consensus standards bodies. The NTTAA directs EPA
to provide Congress, through OMB, explanations when the Agency decides
not to use available and applicable voluntary consensus standards. This
proposal does not involve technical standards. Therefore, EPA is not
considering the use of any voluntary consensus standards.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
Executive Order 12898 (59 FR 7629 (Feb. 16, 1994)) establishes
federal executive policy on environmental justice. Its main provision
directs federal agencies, to the greatest extent practicable and
permitted by law, to make environmental justice part of their mission
by identifying and addressing, as appropriate, disproportionately high
and adverse human health or environmental effects of their programs,
policies, and activities on minority populations and low-income
populations in the United States.
EPA has determined that this action would not have
disproportionately high and adverse human health or environmental
effects on minority or low-income populations. The proposed rule
involves a minor revision that provides administrative relief but does
not change the conformity rule's underlying requirements for regional
conformity analyses.
