[PA 201-4401a; FRL-7570-4]
Approval and Promulgation of Air Quality Implementation Plans;
Pennsylvania; Revised MOBILE6-Based Motor Vehicle Emission Budget for
the Pennsylvania Portion of the Philadelphia-Wilmington-Trenton Ozone
Nonattainment Area
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is taking direct final action to approve a revision to the
Pennsylvania State Implementation Plan (SIP). Specifically, EPA is
acting to approve a revised 2005 highway motor vehicle emission
inventory for the Pennsylvania portion of the Philadelphia-Wilmington-
Trenton (the Philadelphia area) 1-hour ozone attainment plan. This
revised highway vehicle emissions inventory also serves as the 2005
motor vehicle emissions budget for purposes of determining
transportation conformity under the Clean Air Act. The revised mobile
emissions budget was developed using MOBILE6--the most recent available
version of the EPA-developed MOBILE highway motor vehicle emission
factor model. Revision of the mobile budget was a requirement of EPA's
prior approval of the Commonwealth's 1-hour ozone National Ambient Air
Quality Standard (NAAQS) attainment demonstration for the Philadelphia
severe ozone nonattainment area. The intended effect of this direct
final approval action is to approve a SIP revision that will assist
Pennsylvania in attaining and conforming to attainment of the 1-hour
ozone NAAQS standard in the Philadelphia area. This action is being
taken by EPA in accordance with the requirements of the Clean Air Act.
DATES: This rule is effective on December 9, 2003 without further
notice, unless EPA receives adverse written comment by November 10,
2003. If EPA receives such comments, it will publish a timely
withdrawal of the direct final rule in the Federal Register and inform
the public that the rule will not take effect.
ADDRESSES: Comments may be submitted either by mail or electronically.
Written comments should be mailed to Makeba Morris, Chief, Air Quality
Planning Branch, Mailcode 3AP21, U.S. Environmental Protection Agency,
Region III, 1650 Arch Street, Philadelphia, Pennsylvania 19103. Electronic comments should be sent either to morris.makeba@epa.gov or
to http://www.regulations.gov, which is an alternative method for
submitting electronic comments to EPA. To submit comments, please

SUPPLEMENTARY INFORMATION:
I. Background
A. Pennsylvania's SIP-Approved Attainment Demonstration and Mobile
Budget
On October 21, 2001, EPA approved Pennsylvania's 1-hour ozone
attainment demonstration SIP for the Philadelphia area (66 FR 54143).
As part of that approval action, EPA required the Commonwealth to
revise the SIP to include a recalculated 2005 attainment year motor
vehicle transportation conformity emission budget. This 2005 highway
mobile budget was to be updated using the latest version EPA's newest
emission factor model (MOBILE6) within one year of the availability of
that new version of the model. EPA released the MOBILE6 model on
January 29, 2002, and therefore Pennsylvania was required to submit its
revised mobile budget SIP for the Philadelphia area by January 29,
2003.
On January 17, 2003, Pennsylvania formally submitted a revision to
its SIP containing the updated mobile budget, revising using MOBILE6,
for the Philadelphia ozone nonattainment area. On May 28, 2003, EPA
published a notice in the Federal Register (68 FR 31700) declaring this
revised Philadelphia mobile budget adequate for transportation
conformity purposes.
B. Background on the MOBILE Emission Factor Model and Related EPA
Policy
MOBILE is an EPA emissions factor model for estimating pollution
from on-road motor vehicles in states (with the exception of
California, which has developed its own model). The MOBILE model
calculates emissions of volatile organic compounds (VOCs), nitrogen
oxides (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. Among other uses, the MOBILE model
helps 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 policy 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.
The MOBILE model, first developed in 1978, has been updated many
times to reflect changes to motor vehicles and fuel composition, to
incorporate better understanding of vehicle emissions, and to reflect
new emissions programs. EPA announced the release of the MOBILE6
version of the MOBILE model in the January 29, 2002 edition of the
Federal Register (67 FR 4254), as a replacement for a MOBILE5 version
of the model.
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 attainment demonstration plans and
those plans' associated motor vehicle emissions budgets (or budgets).
---------------------------------------------------------------------------
\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 can
be found 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).
---------------------------------------------------------------------------
EPA has implemented this policy in all ozone nonattainment areas
where a state assumed federal Tier 2 benefits in its attainment
demonstration plans according to EPA's April 2000 MOBILE5 guidance,
``MOBILE5 Information Sheet 8: Tier 2 Benefits Using
MOBILE5.'' States whose attainment demonstrations or maintenance plans
include interim MOBILE5-based estimates of the Tier 2 standards were
required to revise and resubmit their budgets within either one or two
years of the final release of MOBILE6.
EPA's October 21, 2001 (66 FR 54143) approval of Pennsylvania's 1-
hour ozone attainment demonstration plan for the Philadelphia area was
based upon an interim mobile budget, with projected reductions from
Tier 2 motor vehicle standards estimated using the MOBILE5 model. EPA's
October 2001 approval of Pennsylvania's 1-hour ozone attainment
demonstration for the Philadelphia area required a MOBILE6-based motor
vehicle emissions budget SIP revision within one year after EPA
released the MOBILE6 model. EPA released the MOBILE6 model on January
29, 2002, therefore Pennsylvania's MOBILE6 mobile budget SIP was due
January 29, 2003.
II. Summary of SIP Revision and EPA's Review
On January 17, 2003, the Commonwealth of Pennsylvania submitted a
SIP revision containing updated inventories of emissions of the ozone
precursors VOC and NOX from highway mobile sources operating
in the Philadelphia ozone attainment area. These summertime inventories
were generated for summertime periods in 1990 and for 2005, the year
Philadelphia is to attain the 1-hour ozone standard. This updated motor
vehicle emissions modeling was generated through use of the newly
released MOBILE6 model. The 2005 motor vehicle emissions inventory
projection also serves as the motor vehicle emissions budget, or mobile
budget, for transportation conformity planning. The Commonwealth's
January 2003 SIP revision is intended to demonstrate that the updated
projections of motor vehicle emissions (calculated using the MOBILE6
emissions factor model) continue to support the demonstrations of
attainment of the 1-hour ozone NAAQS for the Philadelphia area by 2005.
Table 1 below contrasts Pennsylvania's revised MOBILE6-based motor
vehicle emissions inventories with the previously approved MOBILE5-
based inventories for the Philadelphia area, by pollutant, expressed in
units of tons per summer day (tpd). These revised inventories were
developed using the latest available planning assumptions, including
1999 Pennsylvania Department of Transportation vehicle registration
data and 1999 traffic data and information vehicle miles traveled
(VMT). Updated information was used for atmospheric model input (i.e.,
temperature and humidity conditions). Rates of growth for highway
mobile sources have also been updated.

EPA's articulated its policy regarding its policy on the use of
MOBILE6 modeling for purposes of SIP development in several guidance
documents entitled ``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 Areas.''\4\

\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

.
---------------------------------------------------------------------------
Pennsylvania's January 17, 2003 SIP revision includes an
explanation of the differences between the MOBILE5 and MOBILE6-based
inventories. The SIP also provides a comparison of the relative
reduction, by percentage, between the 1990 and 2005 inventories
generated using the two different versions of the models to ensure that
the approved Philadelphia 1-hour ozone attainment demonstration will
continue to demonstrate attainment by 2005. The methodology for this
relative reduction comparison consists of comparing the revised MOBILE6
baseline and attainment case inventories, by pollutant, with the
previously approved (66 FR 54143) MOBILE5 inventory totals for the 5-
county Philadelphia area to determine if attainment can still be
predicted by the attainment date. The Commonwealth then compared these
relative reduction percentages for the MOBILE5 versus MOBILE6
inventories for 1995 and 2005. It should be noted that since the latest
available planning assumptions were used the revised, MOBILE6-based
modeling, this relative reduction comparison is not an exact comparison
of only the differences between the different versions of the MOBILE
models.
Pennsylvania's relative reduction comparison shows that the
reduction in VOC emissions, on a percentage basis, is greater in the
revised MOBILE 6-based inventories than in the previously approved
MOBILE5 inventories. However, the there is a slight increase, on a
percentage basis, in NOX in the revised MOBILE6-based
inventories compared to the previous MOBILE5 inventories. The
Commonwealth argues that the benefit of additional reduction in VOCs
outweighs the slight NOX increase--which the Commonwealth
justifies quantitatively by using a 1.3 to 1 VOC to NOX
substitution ratio to weigh directly the actual VOC to NOX
emissions resultant from the MOBILE5 and MOBILE6-based inventories.
This method of weighting VOC versus NOX emissions shows that
the increased reductions in VOC emissions outweigh the increase in
NOX emissions demonstrated by the MOBILE6-based inventories.
Pennsylvania's choice of VOC to NOX substitution ratios for
this comparison stems from its use in New Source Review emission
trading in the Philadelphia ozone nonattainment area.
EPA's relevant policy guidance also required the Commonwealth to
consider whether growth and control strategy assumptions for other
sources (i.e., point, area, and non-road mobile sources) were still
accurate at the time the revised MOBILE6 budget SIP submission (i.e.,
January 2003). Pennsylvania's SIP revision states that growth and
control strategy assumptions for these other emissions sources have
been reevaluated, with the conclusion that these assumptions for growth
and control strategies continue to be valid for the Philadelphia 1-hour
ozone attainment demonstration.
Pennsylvania's January 17, 2003 SIP revision 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 1-
Hour Ozone NAAQS by the attainment date of 2005 for Pennsylvania
portion of the Philadelphia-Wilmington-Trenton area.
The Revised Mobile Budget
For Pennsylvania's Philadelphia area attainment plan, the mobile
budgets are the on-road components of VOC and NOX emissions
of the 2005 attainment inventories. Table 2 below summarizes
Pennsylvania's revised budgets contained in the January 17, 2003
submittal. These budgets were developed using the latest planning
assumptions, including 1999 vehicle registration data and VMT. Because
Pennsylvania's January 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 1-Hour Ozone NAAQS, EPA
is taking rulemaking action to approve this mobile emissions budget.

III. Final Action
Pennsylvania has adequately demonstrated to EPA that its 1-hour
attainment demonstration SIP for the Philadelphia area (as revised in
by the January 2003 MOBILE6-based highway emissions inventory) will
continue to demonstrate attainment of the ozone NAAQS with the
incorporation of the
[[Page 58611]]
updated highway emissions inventory. EPA is therefore approving the
Pennsylvania SIP revision submitted on January 17, 2003 to revise the
Philadelphia 1990 and 2005 highway mobile VOC and NOX
emissions inventories and the revised 2005 motor vehicle emissions
budget.
EPA is publishing this rule without prior proposal because the
Agency views this as a noncontroversial amendment and anticipates no
adverse comment, as this revision serves the purpose of updating the
highway mobile emissions inventory using the latest version of EPA's
mobile source emission factor model and the most recently available
emissions modeling planning assumptions. This SIP revision is the
result of a requirement to update the highway mobile inventory using
MOBILE6 specified by EPA's October 26, 2001 approval of the
Pennsylvania's 1-hour ozone attainment demonstration for the
Philadelphia area. Also, EPA declared the mobile source inventory
adequate for transportation conformity purposes on May 28, 2003.
However, in the ``Proposed Rules'' section of today's Federal
Register, EPA is publishing a separate document that will serve as the
proposal to approve this SIP revision if adverse comments are filed.
This rule will be effective on December 9, 2003 without further notice
unless EPA receives adverse comment by November 10, 2003. If EPA
receives adverse comment, EPA will publish a timely withdrawal in the
Federal Register informing the public that the rule will not take
effect. EPA will address all public comments in a subsequent final rule
based on the proposed rule. EPA will not institute a second comment
period on this action. Any parties interested in commenting must do so
at this time. Please note that if EPA receives adverse comment on an
amendment, paragraph, or section of this rule and if that provision may
be severed from the remainder of the rule, EPA may adopt as final those
provisions of the rule that are not the subject of an adverse comment.
You may submit comments either electronically or by mail. To ensure
proper receipt by EPA, identify the appropriate rulemaking
identification number (PA 201-4401) in the subject line on the first
page of your comment. Please ensure that your comments are submitted

IV. Statutory and Executive Order Reviews
A. General Requirements
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. 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). 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.). 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 (Public Law 104-4). 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).
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. 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.
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 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. 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.).
B. Submission to Congress and the Comptroller General
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. This rule is not a
``major rule'' as defined by 5 U.S.C. 804(2).
C. Petitions for Judicial Review
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 December 9, 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).)
