Adequacy Determination for the Motor Vehicle Emissions Budgets in 
the Truckee Meadows PM<INF>10</INF> Maintenance Plan for Transportation 
Conformity Purposes; State of Nevada

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of adequacy.

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

SUMMARY: In this notice, EPA is notifying the public that the Agency 
has found that motor vehicle emissions budgets (MVEBs) for particles 
with an aerodynamic diameter of a nominal 10 microns or less 
(PM<INF>10</INF>), contained in the Redesignation Request and 
Maintenance Plan for the Truckee Meadows 24-Hour PM<INF>10</INF> Non-
Attainment Area (``Truckee Meadows PM<INF>10</INF> Maintenance Plan''), 
are adequate for transportation conformity purposes. The Truckee 
Meadows PM<INF>10</INF> Maintenance Plan was submitted to EPA on July 
13, 2009 by the Nevada Division of Environmental Protection as a 
revision to the Nevada State Implementation Plan. As a result of our 
adequacy finding, the Washoe County Regional Transportation Commission 
and the U.S. Department of Transportation must use these budgets in 
future conformity analyses.

DATES: This finding is effective June 2, 2010.

FOR FURTHER INFORMATION CONTACT: Eleanor Kaplan, U.S. EPA, Region IX, 
Air Division AIR-2, 75 Hawthorne Street, San Francisco, CA 94105-3901;

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 Nevada Division of 
Environmental Protection on May 5, 2010 stating that the motor vehicle 
emissions budgets for PM<INF>10</INF> in the submitted Truckee Meadows 
PM<INF>10</INF> Maintenance Plan are adequate. Receipt of these motor 
vehicle emissions budgets was announced on EPA's transportation 
conformity Web site on January 19, 2010, and no comments were 
submitted. The finding is available at EPA's conformity Web site: 
http://www.epa.gov/otaq/stateresources/transconf/adequacy.htm.
    The Truckee Meadows PM<INF>10</INF> Maintenance Plan identifies 
PM<INF>10</INF> MVEBs for the Truckee Meadows nonattainment area for 
years 2009, 2013, 2018 and 2020. The adequate budgets are presented in 
the following table:

 Truckee Meadows PM10 Maintenance Plan Motor Vehicle Emissions Budgets,
                   Truckee Meadows Nonattainment Area
                     [Winter season, pounds per day]
------------------------------------------------------------------------
 
------------------------------------------------------------------------
2009 Emissions Budget..........................................   21,195
2013 Emissions Budget..........................................   20,871
2018 Emissions Budget..........................................   20,836
2020 Emissions Budget..........................................   20,816
------------------------------------------------------------------------

    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 conform. 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 
emissions 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 
while 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.
