II. Background
In November of 1999, EPA issued two memoranda \1\ to articulate its
policy regarding states that incorporated MOBILE5-based interim Tier 2
standard \2\ benefits into their SIPs and MVEBs. Although these
memoranda primarily targeted certain serious and severe ozone
nonattainment areas, EPA has implemented this policy in all other areas
that have made use of federal Tier 2 benefits in air quality plans from
EPA's April 2000 MOBILE5 guidance, ``MOBILE5 Information Sheet
8: Tier 2 Benefits Using MOBILE5.'' All states whose
attainment demonstrations or maintenance plans include interim MOBILE5-
based estimates of the Tier 2 standards were required to make a
commitment to revise and resubmit their MVEBs within either one or two
years of the final release of MOBILE6 in order to gain SIP approval.
---------------------------------------------------------------------------
\1\ Memoranda, ``Guidance on Motor Vehicle Emissions Budgets in
1-Hour Ozone Attainment Demonstrations,'' issued November 3, 1999,
and ``1-Hour Ozone Attainment Demonstrations and Tier2/Sulfur
Rulemaking,'' issued November 8, 1999. Copies of these memoranda are
on EPA's Web site at http://www.epa.gov/otaq/transp/traqconf.htm.
\2\ The final rule on Tier 2 Motor Vehicle Emissions Standards
and Gasoline Sulfur Control Requirements (``Tier 2 standards'') for
passenger cars, light trucks, and larger passenger vehicles was
published on February 10, 2000 (65 FR 6698).
---------------------------------------------------------------------------
On December 26, 2000, Illinois submitted a revision to the One-Hour
Ozone Attainment Demonstration SIP for the Chicago severe ozone area.
This SIP revision included, among other things, revised MVEBs using
interim MOBILE5-based estimates of the Tier 2 standards and an
enforceable commitment to revise the attainment demonstration using the
MOBILE6 model, including MVEBs, within two years of the release of the
model. Additional information on EPA's final approval of Illinois'
December 26, 2000 submittal is in the November 13, 2001 Federal
Register (66 FR 56931).
EPA officially released the MOBILE6 motor vehicle emissions factor
model on January 29, 2002 (67 FR 4254). Thus, the effective date of
that Federal Register notice constituted the start of the two year time
period in which Illinois was required to revise its One-Hour Ozone
Attainment Demonstration SIP using the MOBILE6 model. Illinois was
required to submit this SIP revision to EPA by January 29, 2004.
III. What Is MOBILE6?
MOBILE is an EPA emissions factor model for estimating pollution
from on-road motor vehicles in states outside of California. MOBILE
calculates emissions of volatile organic compounds (VOCs), oxides of
nitrogen (NOX) and carbon monoxide (CO) from passenger cars,
motorcycles, buses, and light-duty and heavy-duty trucks. The model
accounts for the emission impacts of factors such as changes in vehicle
emission standards, changes in vehicle populations and activity, and
variation in local conditions such as temperature, humidity, fuel
quality, and air quality programs.
MOBILE is used to calculate current and future inventories of motor
vehicle emissions at the national and local level. These inventories
are used to make decisions about air pollution policies and programs at
the local, state and national level. Inventories based on MOBILE are
also used to meet the federal Clean Air Act's SIP and transportation
conformity requirements.
MOBILE6 is the first major update of the MOBILE model since 1993.
The MOBILE model was first developed in 1978. It has been updated many
times to reflect changes in the vehicle fleet and fuels, to incorporate
EPA's growing understanding of vehicle emissions, and to cover new
emissions regulations and modeling needs. Although some minor updates
were made in 1996 with the release of MOBILE5b, MOBILE6 is the first
major revision to MOBILE since MOBILE5a was released in 1993.
IV. What Is the Purpose and Content of Illinois' Submittal?
To address its enforceable commitment made in the December 26,
2000, Attainment Demonstration SIP revision, the State submitted a
requested SIP revision on April 11, 2003, which revises the 2005 and
2007 motor vehicle emissions inventories and the 2005 and 2007 MVEBs
using the MOBILE6 model. The April 11, 2003, submittal demonstrates
that the new levels of motor vehicle emissions calculated using MOBILE6
continue to support achievement of the projected attainment of the one-
hour ozone NAAQS for the Chicago area.
V. What Are the Revised MOBILE6 Inventories?
Table 1 below summarizes the revised motor vehicle emissions
inventories in tons per summer day (tpd). The State developed these
revised inventories using the latest planning assumptions, including
updated vehicle registration data, vehicle miles traveled (VMT),
speeds, fleet mix, and SIP control measures. EPA is approving these
revised 2005 and 2007 motor vehicle emissions inventories.

2005 VOC ---------------------
VOC NOX
------------------------------------------------------------------------
Chicago Severe Area.................... 151.11 127.42 280.40
------------------------------------------------------------------------
VI. Are the Revised MOBILE6 Inventories Consistent With Illinois' One-
Hour Ozone Attainment Demonstration?
Illinois' attainment demonstration used photochemical grid
modeling. For one-hour ozone, the daily peak one-hour concentration
predicted in every grid cell by the model was compared to the ozone
standard concentration of 124 parts per billion (ppb). This is best
represented by the deterministic approach described in the 1996
Guidance on Use of Modeled Results to Demonstrate Attainment of the
Ozone NAAQS, EPA, June 1996. That guidance also describes a statistical
approach which allows a specific number of exceedances of the standard.
However, final attainment is still determined in an absolute sense by
comparing a predicted concentration with the one-hour standard value of
124 ppb. EPA has articulated its policy regarding the use of MOBILE6 in
SIP development in its ``Policy Guidance on the Use of MOBILE6 for SIP
Development and Transportation Conformity'' \3\ and ``Clarification of
Policy Guidance for MOBILE6 in Mid-course Review
[[Page 53890]]
Areas.'' \4\ This policy requires that new MOBILE6 MVEBs in areas that
demonstrated attainment with absolute modeling meet two conditions.
First, the new MOBILE6 based mobile source inventories are compared to
the MOBILE5 based inventories for the attainment year. If the MOBILE6
mobile emissions are less than or equal to the MOBILE5 emissions, then
the SIP continues to demonstrate attainment. Second, EPA's policy
guidance requires the State to consider whether growth and control
strategy assumptions for non-motor vehicle sources (i.e., point, area,
and non-road mobile sources) are still accurate at the time the State
developed the submittal.
---------------------------------------------------------------------------
\3\ Memorandum, ``Policy Guidance on the Use of MOBILE6 for SIP
Development and Transportation Conformity,'' issued January 18,
2002. A copy of this memorandum can be found on EPA's Web site at
http://www.epa.gov/otaq/transp/traqconf.htm.
\4\ Memorandum, ``Clarification of Policy Guidance for MOBILE6
SIPs in Mid-course Review Areas,'' issued February 12, 2003. A copy
of this memorandum can be found on EPA's Web site at http://www.epa.gov/otaq/transp/traqconf.htm
.
---------------------------------------------------------------------------
Consistent with this policy guidance, Illinois' updated MOBILE6
inventories were less than the MOBILE5 attainment demonstration
inventories for the Chicago area. It should be noted that Illinois used
the latest planning assumptions in development of the updated
inventories. Illinois reviewed the growth and control strategy
assumptions for non-motor vehicle sources, and concluded that these
assumptions continue to be valid and support the one-hour Ozone
Attainment Demonstration.
In summary, Illinois' April 11, 2003, submittal satisfies the
conditions outlined in EPA's MOBILE6 Policy guidance, and demonstrates
that the new levels of motor vehicle emissions calculated using MOBILE6
continue to support achievement of the projected attainment of the one-
Hour Ozone NAAQS by the attainment date of 2007.
VII. Are Illinois' Motor Vehicle Emissions Budgets Approvable?
Table 2 below summarizes Illinois' revised 2005, and 2007 MVEBs
contained in the April 11, 2003, submittal. The State developed MVEBs
using the latest planning assumptions, including updated vehicle
registration data, vehicle miles of travel (VMT), speeds, fleet mix,
and SIP control measures. The Illinois submittal met all applicable
requirements and EPA is approving these budgets.

VIII. EPA Action
EPA is approving the Illinois SIP revision submitted on April 11,
2003. This submittal revises Illinois' 2005, and 2007 motor vehicle
emission inventories and 2005, and 2007 MVEBs using MOBILE6 for the
Chicago severe 1-hour ozone nonattainment area.
EPA is publishing this action without prior proposal, because EPA
views this as a noncontroversial revision and anticipates no adverse
comments. However, in a separate document in this Federal Register
publication, EPA is proposing to approve the SIP revision should
adverse written comments be filed. This action will be effective
without further notice unless EPA receives relevant adverse written
comments by October 15, 2003. Should the Agency receive such comment,
we will publish a final rule informing the public that this action will
not take effect. Any parties interested in commenting on this action
should do so at this time. If we do not receive comments, this action
will be effective on November 14, 2003.
IX. Statutory and Executive Order Reviews
Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is not a ``significant regulatory action'' and therefore is not
subject to review by the Office of Management and Budget.
Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
For this reason, this action is also not subject to Executive Order
13211, ``Actions Concerning Regulations That Significantly Affect
Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001).
Regulatory Flexibility Act
This action merely approves state law as meeting Federal
requirements and imposes no additional requirements beyond those
imposed by state law. Accordingly, the Administrator certifies that
this rule will not have a significant economic impact on a substantial
number of small entities under the Regulatory Flexibility Act (5 U.S.C.
601 et seq.).
Unfunded Mandates Reform Act
Because this rule approves pre-existing requirements under state
law and does not impose any additional enforceable duty beyond that
required by state law, it does not contain any unfunded mandate or
significantly or uniquely affect small governments, as described in the
Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).
Executive Order 13175: Consultation and Coordination With Indian Tribal
Governments
This rule also does not have tribal implications because it will
not have a substantial direct effect on one or more Indian tribes, on
the relationship between the Federal Government and Indian tribes, or
on the distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified by Executive Order 13175 (65
FR 67249, November 9, 2000).
Executive Order 13132: Federalism
This action also does not have Federalism implications because it
does not have substantial direct effects on the States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government, as specified in Executive Order 13132 (64 FR 43255, August
10, 1999). This action 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 Clean Air
Act.
Executive Order 13045: Protection of Children From Environmental Health
and Safety Risks
This rule also is not subject to Executive Order 13045 ``Protection
of Children from Environmental Health Risks and Safety Risks'' (62 FR
19885, April 23, 1997), because it is not economically significant.
National Technology Transfer Advancement Act
In reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act. In
this context, in the absence of a prior existing requirement for the
State to use voluntary consensus standards (VCS), EPA has no authority
to disapprove a SIP submission for failure to use VCS. It would thus be
inconsistent with applicable law for
[[Page 53891]]
EPA, when it reviews a SIP submission, to use VCS in place of a SIP
submission that otherwise satisfies the provisions of the Clean Air
Act. Thus, the requirements of section 12(d) of the National Technology
Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply.
Paperwork Reduction Act
This rule does not impose an information collection burden under
the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501
et seq.).
Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this rule and other
required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A major rule cannot
take effect until 60 days after it is published in the Federal
Register. This action is not a ``major rule'' as defined by 5 U.S.C.
804(2).
Under section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by November 14, 2003. Filing a
petition for reconsideration by the Administrator of this final rule
does not affect the finality of this rule for the purposes of judicial
review nor does it extend the time within which a petition for judicial
review may be filed, and shall not postpone the effectiveness of such
rule or action. This action may not be challenged later in proceedings
to enforce its requirements. (See section 307(b)(2).)
