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.

------------------------------------------------------------------------

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).)
