Adequacy Status of the San Joaquin Valley Unified Air Pollution 
Control District, California, Submitted Ozone Attainment Plan for 
Transportation Conformity Purposes

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of adequacy determination.

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

SUMMARY: In this notice, EPA is notifying the public that we have found 
that the motor vehicle emissions budgets contained in the submitted 
2004 State Implementation Plan for Ozone in the San Joaquin Valley are 
adequate for transportation conformity purposes.
    As a result of our finding, the various transportation planning 
agencies in the San Joaquin Valley and the Federal Highway 
Administration must use the VOC and NOX motor vehicle 
emissions budgets from the submitted 2004 State Implementation Plan for 
Ozone in the San Joaquin Valley for future conformity determinations.

DATES: This determination is effective March 2, 2005.

FOR FURTHER INFORMATION CONTACT: The finding is available at EPA's 
conformity Web site: http://www.epa.gov/oms/transp/traqconf.htm (once 
there, click on the ``Transportation Conformity'' link, then look for 
``Adequacy Web Pages'').
    You may also contact David Wampler, U.S. EPA, Region IX, Air 
Division AIR-2, 75 Hawthorne Street, San Francisco, CA 94105; (415) 
972-3975, or [email protected].

SUPPLEMENTARY INFORMATION: This notice announces our finding that the 
emissions budgets contained in the 2004 State Implementation Plan \1\ 
for Ozone in the San Joaquin Valley (``Ozone Plan''), submitted by the 
State of California on behalf of the San Joaquin Valley Unified Air 
Pollution Control District on November 15, 2004, are adequate for 
transportation conformity purposes. EPA Region IX made this finding in 
a letter to the State of California, Air Resources Board on February 7, 
2005. We are also announcing this finding on our conformity Web site: 
http://www.epa.gov/oms/transp/traqconf.htm (once there, click on the 
``Transportation Conformity'' link, then look for ``Adequacy Web 
Pages'').
---------------------------------------------------------------------------

    \1\ The submitted Ozone Plan includes a rate-of-progress 
demonstration for milestone years 2008 and 2010 and a demonstration 
that the San Joaquin Valley will attain by no later than the 2010 
attainment date for areas classified ``extreme'' under the federal 
1-hour ozone standard.
---------------------------------------------------------------------------

    Transportation conformity is required by section 176(c) of the 
Clean Air Act. Our conformity rule requires that transportation plans, 
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). One of these criteria is that the motor vehicle 
emissions budgets, when considered together with all other emission 
sources, is consistent with applicable requirements for the reasonable 
further progress plan. We have preliminarily determined that the 2004 
State Implementation Plan for Ozone in the San Joaquin Valley plan 
meets the necessary rate of progress reductions for milestone years 
2008 and 2010 and demonstrates attainment by no later than 2010. 
Therefore, the motor vehicle emissions budgets can be found adequate. 
Please note that an adequacy review is separate from EPA's completeness 
review, and it also should not be used to prejudge EPA's ultimate 
approval of the submitted plan itself. Even if we find a budget 
adequate, the submitted plan could later be disapproved.
    We have described our process for determining the adequacy of 
submitted SIP budgets in guidance (May 14, 1999 memo titled 
``Conformity Guidance on Implementation of March 2, 1999 Conformity 
Court Decision''). This guidance is now reflected in the amended 
transportation conformity rule, July 1, 2004 (69 FR 40004), and in the 
correction notice, July 20, 2004 (69 FR 43325). We followed this 
process in making our adequacy determination on the motor vehicle 
emissions budgets contained in the 2004 State Implementation Plan for 
Ozone in the San Joaquin Valley.

    Authority: 42 U.S.C. 7401-7671q.

    Dated: February 8, 2005.

Acting Regional Administrator, Region IX.
