[FRL-6841-6]

Motor Vehicle Emissions Budgets in
Attainment Demonstrations for the
One-Hour National Ambient Air Quality
Standard for Ozone

AGENCY: Environmental Protection
Agency (EPA).
ACTION: Supplemental notice of
proposed rule.

SUMMARY: On December 16, 1999, we
(EPA) proposed to approve or
conditionally approve and disapprove
in the alternative attainment
demonstration State implementation
plans (SIPs) for ten areas in the eastern
United States (64 FR 70317). In today's
supplemental notice, we are clarifying
and expanding on two issues relating to
the motor vehicle emissions budgets in
these SIPs. In addition, we are
reopening the comment period to take
comment on these two issues and to
allow comment on any additional
materials that were placed in the
dockets for the proposed actions close to
or after the initial comment period
closed  on February 14, 2000.
  First, we are proposing to clarify what
occurs  if we finalize conditional or full
approval of any of these SIPs based on
a State commitment to revise the SIP's
motor vehicle emissions budgets in the
future. If this occurs, the motor vehicle
emissions budgets in the approved SIP
will apply for transportation conformity
purposes only until the budgets are
revised consistent with the commitment
and we have found the new budgets
adequate. Once we have  found the
newly revised budgets adequate, then
they would apply instead of the
previous conditionally or fully
approved budgets.
  Second, we are proposing that States
may opt to commit to revise their
emissions budgets 1 year after the
release of MOBILE6, as originally
proposed on December 16, 1999. Or,
States may commit to a new option, i.e.,
to revise their budgets 2 years  following
the release of MOBILE6,  provided that
conformity is not determined without
adequate MOBILE6 SIP budgets during
the second year.
DATES: Comments must be received on
or before August 28, 2000.
ADDRESSES: Written comments on this
action should be addressed to  the EPA
regional offices responsible for the areas
addressed by the SIPs we are reopening.
Contact names and addresses for these
regional offices are included below in
SUPPLEMENTARY INFORMATION.

I. Background Information

A. What Did We Propose on December
16, 1999?
  We proposed to conditionally or fully
approve, and in the alternative to
disapprove, ozone attainment
demonstration (SIPs) for ten areas. The
ten areas are described below. Our
proposals, all of which were published
on December 16, 1999, contain a full
explanation of the background and
proposed actions  for the following areas:
Atlanta, 64 FR 70478; Houston-
Galveston, 64 FR 70548; Metropolitan
Washington, DC, 64 FR 70460;
Milwaukee^lacine, 64 FR 70531;
Springfield, 64 FR 70319; Greater
Connecticut, 64 FR 70332; Baltimore, 64
FR 70397; Chicago-Gary4,ake County,
64 FR 70514 and 64 FR 70496;
Philadelphia-Wilmington-Trenton, 64
FR 70412, 64 FR 70428, 64 FR 70444
and 64 FR 70380; and New York-
Northern New Jersey-Long Island, 64 FR
70380, 64 FR 70348, 64 FR 70364. For
more detail, see the December proposals
as cited above.
  In order to conditionally or fully
approve the attainment demonstration
SIPs, we proposed that several areas
needed to commit to adopt additional
control measures to achieve the level of
emissions reductions that we identified
as necessary to attain the 1-hour ozone
standard. We also proposed that these
areas must commit to recalculate and
submit revised motor vehicle emissions
budgets that include the effects of the
measures that are ultimately adopted, if
those measures pertain to motor
vehicles. We explain the term "motor
vehicle emissions budget" in item C
below.
  In addition, we proposed that where
a SIP includes the benefits of EPA's Tier
2/Sulfur program, the State must
commit to revise the SIP's motor vehicle
emissions budgets within 1 year after
we release the MOBILE6 model. This
commitment would be necessary in
order for us to approve the SIP.
  Our December 16, 1999 proposals also
addressed many other issues that are not
directly relevant to today's
supplemental proposal. We direct the
reader  to the December proposals for
more details.

B. What Is Transportation Conformity?
  Transportation conformity is a Clean
Air Act (CAA) requirement for
metropolitan planning organizations
and the U.S. Department of
Transportation to ensure that federally
supported highway and transit activities
are consistent with ("conform to") the
SIP.  Conformity to a SIP means that an
action  will not cause or contribute to
new violations; worsen existing
violations; or delay timely attainment.
  The  conformity requirements are
established by CAA section 176(c). We
issued  the transportation conformity
rule  (40 CFR part 93) to implement this
CAA requirement.
C. What Are Motor Vehicle Emissions
Budgets?
  As described in CAA section
176(c)(2)(A), attainment demonstrations
necessarily include estimates of motor
vehicle emissions to help areas reach
attainment. These estimates act as a
budget or ceiling for emissions from
motor vehicles, and are used in
conformity to determine whether
transportation plans and projects
conform to the attainment SIP. In order
for transportation plans and projects to
conform, estimated emissions from
transportation plans and projects must
not exceed the emission budgets
contained in the attainment
demonstration.

D. Which Motor Vehicle Emissions
Budgets Usually Apply?

  According to the transportation
conformity rule, motor vehicle
emissions budgets ("budgets") in a
submitted SIP apply for conformity
purposes even before we have approved
the SIP, under certain circumstances.
First, there must not be any other
approved SIP budgets that have been
established for the same timeframe and
with respect to the same CAA
requirements. For example, if there is
already an approved attainment
demonstration SIP that establishes
budgets for the attainment date, and the
State submits a revision to those
budgets, the newly submitted budgets
do not apply for conformity purposes
until we have approved them into the
SIP.
  Second, submitted SIP budgets cannot
be used before we have approved the
SIP unless we  have found that the
submitted SIP budgets are  adequate for
conformity purposes. Our process for
determining adequacy is explained at 40
CFR 93.118(e)  and EPA's May 14,  1999
memo  entitled, "Conformity Guidance
on Implementation of March 2, 1999
Conformity Court Decision."
  For more details about the
applicability of submitted  and approved
budgets, see 61 FR 36117 (July 9, 1996)
and 62 FR 43783 (August 15, 1997).

II. What Is EPA Proposing Today?

  Today, we are proposing to
supplement and clarify our December
16, 1999 proposals to conditionally or
fully approve (and disapprove in the
alternative) the attainment
demonstration SIPs for ten areas. As
discussed below, our supplemental
notice  addresses two issues specifically
pertaining to the motor vehicle
emissions budgets in these SIPs.
  In addition,  we are reopening the
comment period so the public may
comment on these two issues and may
consider and comment on  any
additional materials that have been
placed in the docket for each of these
proposed rules close to or after the
February 14, 2000 date of the initial
comment period. We are also reopening
the comment period for all issues with
respect to the Pennsylvania portion of
the Philadelphia-Wilmington-Trenton
nonattainment area based on requests
received from the State of Pennsylvania
and other interested parties during the
initial  comment period.

Federal Register/Vol. 65, No.  146/Friday, July 28, 2000/Proposed Rules
A. Clarification of the Applicability of
Revised Budgets
I. How Are We Proposing to Clarify the
Applicability of Revised Budgets?
  In today's notice, we are proposing to
clarify what occurs if we finalize
approval or conditional approval of any
of the December 16, 1999 SIPs based on
a State commitment to revise the
budgets in the future. If this occurs, the
approved SIP budgets will apply for
conformity purposes only until the
revised budgets have been submitted
and we have found the submitted
budgets to be adequate for conformity
purposes.
  In other words, when the State
submits revised budgets as they have
committed, those revised budgets will
apply for conformity purposes as soon
as we have found those budgets to be
adequate for conformity purposes and
our adequacy finding is effective. The
revised budgets would then replace the
budgets in the approved (or
conditionally approved) attainment
demonstration SIP, provided that (as we
expect) the revised budgets are
submitted as a revision to part of the
attainment demonstration SIP and are
established for the same year as those in
the approved SIP.
2. Why Are We Proposing to Clarify the
Applicability of Revised Budgets?
  In December 1999, we proposed that
we would not approve the attainment
demonstration SIPs from certain areas
unless the States commit to revise the
SIPs' budgets in the future. As described
in section I.A. of this preamble,
emissions budgets must be revised to
reflect the effects of additional control
measures that a State has committed to
adopt. The budgets must also be revised
within 1 year after we release MOBILE6,
if the budget that is approved reflects
the benefits of our Tier 2/Sulfur
regulation.
  Since we are proposing to approve
budgets only because the States have
committed to revise them, we want our
approval of the budgets to last only until
adequate revised budgets are submitted
pursuant to the commitments. We
believe the revised budgets should
apply as soon as we find them adequate;
we do not believe it is appropriate to
wait until we have approved the revised
attainment demonstration SIP. This is
because we know now that once we
have confirmed that the revised budgets
are adequate, they will be more
appropriate than the  originally
approved budgets for conformity
purposes.
  Specifically, once an area has adopted
additional measures that affect motor
                    vehicle emissions, an appropriate motor
                    vehicle emissions budget must reflect
                    those measures. Otherwise, the budget
                    would not be the level of motor vehicle
                    emissions that is consistent with the
                    attainment demonstration; it would be
                    inappropriately large.
                      In addition, we know now that we
                    cannot accurately estimate the benefits
                    of the Tier 2 program until we release
                    the MOBILE6 model. We are proposing
                    to approve budgets based on interim
                    approximations of Tier 2 benefits only
                    because the States are committing to
                    recalculate the budgets using MOBILE6
                    in a timely fashion.
                      If we do not clarify our proposed
                    approval of the  budgets, States will
                    revise their budgets as they have
                    committed, but they will not be able to
                    start using them quickly for conformity
                    purposes. This would defeat the
                    purpose of our original requirement for
                    the budgets to be revised quickly. In
                    contrast, according to today's proposal,
                    the revised budgets could be used for
                    conformity after we have completed our
                    adequacy review process, which we
                    have committed to complete within 90
                    days after revisions are submitted,
                    provided they are adequate.
                      This supplemental notice does not
                    propose any change to the existing
                    transportation conformity rule or to the
                    way it is normally implemented with
                    respect to other submitted and approved
                    SIPs, which do  not contain
                    commitments to revise  the budgets.
                    3. How Does the 18-Month Clock Apply
                    With Respect to These Budget
                    Revisions?
                      Section 93.104(e)(2) of the conformity
                    rule requires conformity of the
                    transportation plan and transportation
                    improvement program (TIP) to be
                    redetermined within 18 months
                    following the date of a State's initial
                    submission of each SIP establishing a
                    budget.
                      As described  at 60 FR 44792 (August
                    29, 1995), the first submission of a given
                    type of SIP that establishes a budget
                    (e.g., an ozone attainment
                    demonstration) starts the 18^Ilonth
                    clock for redetermining conformity.
                    However, the 18-month, clock is
                    unaffected by subsequent changes to
                    that submitted SIP.
                      Therefore, the revisions to the
                    attainment demonstration SIPs to reflect
                    additional measures or MOBILE6 will
                    not start a new ISnnonth clock. Of
                    course, whenever conformity is
                    eventually determined in accordance
                    with the ISnnonth clock, the
                    demonstration must use whatever
                    budgets are applicable at that time. If an
                    initial submission starts the
clock but then is changed and the
revised budgets are found adequate, any
subsequent conformity determination
must use the new,  adequate budgets.
  Section 93.104(e)(3) also requires
conformity of the transportation plan
and TIP to be redetermined 18 months
following our approval of a SIP that
establishes or revises a budget. If we
conditionally approve an ozone
attainment demonstration, an ISnnonth
clock will be started on the  effective
date of our conditional approval. A
subsequent conversion of the
conditional approval to full approval
will not start another 18^Ilonth clock,
unless  the budgets we are approving
have changed since the conditional
approval.
B. Additional Option for Timing of
Budget Revision Following MOBILES

1. What Is the Additional Option?
  In our December 16,  1999 proposal to
approve and/or disapprove  SIPs for ten
urban areas, we stated that if a SIP
relied on Tier 2 benefits to demonstrate
attainment, States would need to
commit to revise their motor vehicle
emissions budgets  within 1  year after
we release MOBILE6, in order for us to
approve the SIP.
  We proposed that States recalculate
their budgets using MOBILE6 because
the  emission reduction benefits of Tier
2 cannot be properly estimated until
MOBILE6 is released. The estimates of
Tier 2 benefits that are  currently in
submitted SIPs are interim
approximations.
  In this supplemental notice we are
proposing that the  affected States may
have a  1-year extension of time to revise
their emissions budgets, under certain
circumstances. Specifically, a State may
commit to revise its SIP's budgets
within 2 years after MOBILE6 is
released, if the State also commits that
conformity will not be  determined
during the additional year unless there
are adequate SIP budgets in place that
were developed using MOBILE61. As
part of this commitment, we also are
proposing that States inform affected
metropolitan planning  organizations
and their State transportation
departments of this requirement.
  States may opt to commit to revise
their emissions budgets 1 year after the
release of MOBILE6, as originally
proposed on December 16, 1999. Or,
States may commit to the new option,
i.e., to  revise their budgets 2 years
  1 This concept was discussed in a letter dated
March 6, 2000 from John S. Seitz, Director, Office
of Air Quality Planning and Standards to Ralph
Marquez, Commissioner, Texas Natural Resources
Conservation Commission,

-------
                   Federal Register/Vol. 65, No.  146/Friday, July 28, 2000/Proposed Rules
                                                                      46387
following the release of MOBILES,
provided that conformity is not
determined without adequate MOBILES
SIP budgets during the second year. Any
SIPs that rely on Tier 2 benefits must be
accompanied by one of these two types
of commitments in order for us to find
the budgets adequate for conformity
purposes, and in order for us to finalize
approval of the  SIP. The commitment
must be subject to a public hearing and
fully enforceable as part of the SIP
before we can finalize approval of the
SIP.
2. How Is "Release of MOBILES"
Defined?
  We will publish a notice of
availability in the Federal Register that
announces the formal release of
MOBILES. The date of publication of
that Federal Register notice will
constitute "release of MOBILES" for the
purposes of the commitments discussed
in this supplemental proposal.
3. Why Are We  Proposing This
Additional Option?
  We are proposing to provide States
with this additional option in response
to a comment on the December 16,  1999
proposal. That comment indicated that
in some areas, allowing more than 1
year to revise and adopt a new motor
vehicle emissions budget based on the
MOBILES model would  better  suit an
area's schedule  for SIP revisions and
updates.
  We believe that allowing areas an
additional year  to revise their budgets
using MOBILES will not cause any
environmental harm as long as during
that time there are no new conformity
determinations  that rely on  the older
MOBILES budgets.
C. Reopening of the Public Comment
Period
  The EPA is reopening  the comment
period for 30 days to take comment on
the proposed approach,  discussed
above. In addition, we are reopening the
comment period for all ten areas to
address additional  information that has
been placed in the docket close to or
since the initial comment period
concluded on February 14, 2000. In
general, these materials consist of motor
vehicle emissions budgets, and revised
or additional commitments  or
reaffirmations submitted by the States.
Interested persons should contact the
appropriate regional contact listed in
the SUPPLEMENTARY INFORMATION section
with any questions regarding whether
new information has been placed in the
docket for a specific proposed  action.
  In addition, based on requests
received  during the initial comment
period, EPA is reopening the comment
period for 30 days with respect to all
issues concerning the Pennsylvania
portion of the Philadelphia-Wilmington-
Trenton area.
  We are not, however, reopening the
separate comment period on the
adequacy of motor vehicle emissions
budgets, which was started by
notification on our adequacy website.
Notably, comments  on the adequacy of
motor vehicle emissions budgets are
accepted through a distinct,
administrative process established by
our conformity regulations, known as
adequacy review. That process was not
started for any area covered by today's
notice until all materials relevant to the
budgets had been submitted.

III. Administrative Requirements
A. Executive Order 12866
  The Office of Management and Budget
(OMB) has exempted this regulatory
action from Executive Order 12866,
entitled "Regulatory Planning and
Review."
B. Executive Order 13045
  Protection of Children from
Environmental Health Risks and Safety
Risks (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 does not involve
decisions intended to mitigate
environmental health or safety risks.
C. Executive Order 13084
  Under Executive Order 13084, EPA
may not issue a regulation that is not
required by statute,  that significantly
affects 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 OMB, 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 proposed rule does not
significantly or uniquely affect the
communities of Indian tribal
governments. This action does not
involve or impose any requirements that
affect Indian Tribes. Accordingly, the
requirements of section 3(b) of
Executive Order 13084 do not apply to
this rule.
D. Executive Order 13132
  Executive Order 13132, Federalism
(64 FR 43255, August 10, 1999), revokes
and replaces Executive Orders 12612
(Federalism) and 12875 (Enhancing the
Intergovernmental Partnership).
Executive Order 13132 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." Under Executive
Order 13132, EPA may not issue  a
regulation that has federalism
implications, that imposes substantial
direct compliance costs, and that is not
required by statute,  unless the Federal
government provides the funds
necessary to pay the direct compliance
costs incurred by State and local
governments, or EPA consults with
State and local officials early in the
process of developing  the proposed
regulation. The EPA also may not issue
a regulation that has federalism
implications and that preempts State
law unless the Agency consults with
State and local officials early in the
process of developing  the proposed
regulation.
  This rule will not have substantial
direct effects  on  the States, on the
relationship between the national
government and the States, or on the

-------
46388
Federal Register/Vol. 65, No.  146/Friday, July 28,  2000/Proposed Rules
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132, because it
merely approves a State rule
implementing a federal standard,  and
does not alter the relationship or the
distribution of power and
responsibilities established in the CAA.
Thus, the requirements of section 6 of
the Executive Order do not apply to this
rule.
E. Regulatory Flexibility Act (RFA)
  The RFA generally requires an agency
to conduct a regulatory flexibility
analysis of any  rule subject to notice
and comment rulemaking requirements
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 noMor-profit
enterprises,  and small governmental
jurisdictions.
  This rule will not have a significant
impact on a substantial number of small
entities because SIP approvals under
section 110 and subchapter I, partD of
the CAA do  not create any new
requirements but simply approve
requirements that the State is already
imposing. Therefore, because the
Federal SIP approval does not create
any new requirements, I certify that this
action will not have a significant
economic impact on a substantial
number of small entities.
  Moreover, due to the nature of the
Federal/State relationship under the
CAA, preparation of flexibility analysis
would constitute Federal inquiry into
the economic reasonableness of State
action. The CAA forbids EPA to base its
actions concerning SIPs on such
grounds. Union Electric Co., v. U.S.
EPA, 427 U.S. 246, 255-66 (1976); 42
U.S.C. 7410(a)(2).
  If the conditional approval is
converted to a disapproval under
section 110(k), based on a State's failure
to meet the commitment, it will not
affect any existing State  requirements
applicable to small entities. Federal
disapproval of the State  submittal does
not affect State-enforceability.
Moreover, EPA's disapproval of the
submittal does not impose any new
requirements. Therefore, I certify that
such a proposed disapproval action will
not have a significant economic impact
on a substantial number of small entities
because it would not remove existing
requirements nor would it substitute a
new Federal requirement.
  The EPA's alternative proposed
disapproval of the State  request under
section 110 and subchapter I, partD of
the CAA would not affect any existing
                    requirements applicable to small
                    entities. Any pre-existing Federal
                    requirements would remain in place
                    after this disapproval. Federal
                    disapproval of the State submittal does
                    not affect State-enforceability. Moreover
                    EPA's disapproval of the submittal
                    would not impose any new Federal
                    requirements.  Therefore, I certify that
                    the proposed disapproval would not
                    have a significant impact on a
                    substantial number of small entities.
                    F. Unfunded Mandates Reform 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
                    that includes a Federal mandate that
                    may result in estimated costs to State,
                    local, or tribal governments in the
                    aggregate; or to the private sector, of
                    $100 million or more. Under  section
                    205, EPA must select the most cost-
                    effective and least burdensome
                    alternative that achieves the objectives
                    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
                    or uniquely impacted by the rule.
                      The EPA has determined that the
                    approval action proposed does not
                    include a Federal mandate that may
                    result in estimated costs of $100 million
                    or more to either State, local, or tribal
                    governments in the aggregate, or to the
                    private sector. This Federal action
                    proposes to approve pre-existing
                    requirements under State or local law,
                    and imposes no new requirements.
                    Accordingly, no additional costs to
                    State, local, or tribal governments, or to
                    the private sector, result from this
                    proposed action.
                      Sections 202 and 205 do not apply to
                    the proposed disapproval because the
                    proposed disapproval of the SIP
                    submittal would not, in and of itself,
                    constitute a Federal mandate because it
                    would not impose an enforceable duty
                    on any entity. In addition, the CAA does
                    not permit EPA to consider the types of
                    analyses described in  section 202 in
                    determining whether a SIP submittal
                    meets the CAA. Finally, section 203
                    does not apply to the proposed
                    disapproval because it would affect only
                    the State governments, which are not
                    small governments.
                    G. National Technology Transfer and
                    Advancement Act (NTTAA)
                      Section 12 of the National Technology
                    Transfer and Advancement Act of 1995
                    requires Federal agencies to evaluate
existing technical standards when
developing new regulations. To comply
with NTTAA, EPA must consider and
use "voluntary consensus standards"
(VCS) if available and applicable when
developing programs and policies
unless doing so would be inconsistent
with applicable law or otherwise
impractical.
  The EPA believes that VCS are
inapplicable to the regulatory actions in
this supplemental notice. Today's
actions do not require the public to
perform activities conducive to the use
of VCS.

H. Paperwork Reduction Act

  This supplemental notice of proposed
rule does not impose any new
information collection requirements
from EPA which require approval by
OMB under the Paperwork  Reduction
Act of 1980, 44 U.S.C. 3501 et seq. 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.
  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 purposes 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.
