Adequacy Status of Motor Vehicle Emissions Budgets in Submitted
Coachella Valley 8-hour Ozone Early Progress Plan for Transportation
Conformity Purposes; California
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of Adequacy.
-----------------------------------------------------------------------
SUMMARY: In this notice, EPA is notifying the public that the Agency
has found that the motor vehicle emissions budgets for 8-hour ozone in
the Coachella Valley 8-hour Ozone Early Progress Plan are adequate for
transportation conformity purposes. The Coachella Valley 8-hour Ozone
Early Progress Plan was submitted to EPA on March 24, 2008 by the
California Air Resources Board as a revision to the California State
Implementation Plan (SIP). As a result of our adequacy findings, the
Southern California Association of Governments and the U.S. Department
of Transportation must use these budgets in future conformity analyses
once the finding becomes effective.
DATES: This finding is effective May 22, 2008.
FOR FURTHER INFORMATION CONTACT: Rebecca Rosen, U.S. EPA, Region IX,
Air Division AIR-2, 75 Hawthorne Street, San Francisco, CA 94105-3901;
(415) 947-4154 or rosen.rebecca@epa.gov.
SUPPLEMENTARY INFORMATION: Throughout this document, whenever ``we,''
``us,'' or ``our'' is used, we mean EPA.
Today's notice is simply an announcement of a finding that we have
already made. EPA Region IX sent a letter to the California Air
Resources Board on April 16, 2008 stating that the motor vehicle
emissions budgets in the submitted Coachella Valley 8-hour Ozone Early
Progress Plan for 2012 are adequate. The finding is available at EPA's
conformity Web site: http://www.epa.gov/otag/stateresources/transconf/
adequacy.htm. The adequate motor vehicle emissions budgets are provided
in the following table:
Motor Vehicle Emissions Budgets
------------------------------------------------------------------------
Volatile Nitrogen
organic oxides
compounds ------------
Budget year \1\
------------- (tons per
(tons per day)
day)
------------------------------------------------------------------------
2012.......................................... 7 26
------------------------------------------------------------------------
\1\ The plan uses a comparable State term, reactive organic gases (ROG).
Transportation conformity is required by Clean Air Act section
176(c). EPA's conformity rule requires that transportation plans,
transportation improvement programs, and projects conform to state air
quality implementation plans (SIPs) and establishes the criteria and
procedures for determining whether or not they do. Conformity to a SIP
means that transportation activities will not produce new air quality
violations, worsen existing violations, or delay timely attainment of
the national ambient air quality standards.
The criteria by which we determine whether a SIP's motor vehicle
emission budgets are adequate for conformity purposes are outlined in
40 CFR 93.118(e)(4). We have described our process for determining the
adequacy of submitted SIP budgets in our July 1, 2004 preamble starting
at 69 FR 40038 and we used the information in these resources in making
our adequacy determination. Please note that an adequacy review is
separate from EPA's completeness review, and should not be used to
prejudge EPA's ultimate approval action for the SIP. Even if we find a
budget adequate, the SIP could later be disapproved.
Authority: 42 U.S.C. 7401 et seq.
Dated: April 16, 2008.

Deputy Regional Administrator, Region IX.
