ENVIRONMENTAL PROTECTION AGENCY
[EPA-R09-OAR-2010-0208; FRL-9152-5]
Adequacy Determination for the Motor Vehicle Emissions Budgets in
the Truckee Meadows PM10 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
(PM10), contained in the Redesignation Request and
Maintenance Plan for the Truckee Meadows 24-Hour PM10 Non-
Attainment Area (``Truckee Meadows PM10 Maintenance Plan''),
are adequate for transportation conformity purposes. The Truckee
Meadows PM10 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;
(415) 947-4147 or [email protected].

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 PM10 in the submitted Truckee Meadows
PM10 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 PM10 Maintenance Plan identifies
PM10 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.
