ENVIRONMENTAL PROTECTION AGENCY

[EPA-R10-OAR-2013-0005: FRL-9931-60-Region 10]

Adequacy Determination for the Klamath Falls, Oregon PM2.5 State 
Implementation Plan for Transportation Conformity Purposes

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of adequacy determination.

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

SUMMARY: The Environmental Protection Agency (EPA) is notifying the 
public of its finding that the motor vehicle emissions budgets (MVEBs) 
for particulate matter with an aerodynamic diameter of a nominal 2.5 
microns or less (PM2.5) and nitrogen oxides (NOX) 
in the Klamath Falls PM2.5 state implementation plan (SIP or 
attainment plan) are adequate for transportation conformity purposes. 
The attainment plan was submitted to the EPA by the State of Oregon 
Department of Environmental Quality (DEQ or the State) on December 12, 
2012, with a clarification to the MVEB submitted on December 19, 2013. 
As a result of this adequacy finding, the Oregon DEQ, the Oregon 
Department of Transportation, and the U.S. Department of Transportation 
will be required to use these MVEBs for future transportation 
conformity determinations.

DATES: This finding is effective August 17, 2015.

FOR FURTHER INFORMATION CONTACT: The finding will be available at the 
EPA's conformity Web site: http://www.epa.gov/otaq/stateresources/transconf/adequacy.htm. You may also contact Dr. Karl Pepple, U.S. EPA, 
Region 10 (OAWT-107), 1200 Sixth Ave., Suite 900, Seattle WA 98101;

SUPPLEMENTARY INFORMATION: This action provides notice of the EPA's 
adequacy finding regarding the MVEBs located in the attainment plan for 
the 2006 PM2.5 national ambient air quality standards for 
purposes of transportation conformity. The EPA's finding was made 
pursuant to the adequacy review process for state attainment plan 
submissions delineated at 40 CFR 93.118(f)(1) under which the EPA 
reviews the adequacy of an attainment plan submission prior to the 
EPA's final action on the attainment plan.
    Before the attainment plan was submitted to the EPA, consultation 
among federal, State, and local agencies occurred. Full attainment plan 
documentation was provided to EPA, and EPA's stated concerns were 
addressed. The State submitted the attainment plan to the EPA on 
December 12, 2012 with a clarification to the MVEBs submitted on 
December 19, 2013. Pursuant to 40 CFR 93.118(f)(1), the EPA notified 
the public of its receipt of this plan and its review for an adequacy 
determination on the EPA's Web site and requested public comment by no 
later than April 9, 2015. The EPA received no comments on the plan 
during the comment period. As part of our analysis, we also reviewed 
the State's compilation of public comments and response to comments 
that were submitted during the State's public process for the 
attainment plan. The State subsequently provided a clarification to the 
MVEBs in the attainment plan on December 19, 2013. The EPA finds that 
the MVEBs in the attainment plan, as clarified, are adequate for 
purposes of transportation conformity. There were no other comments 
directed at the on-road portion of the attainment plan that were 
submitted during the State public process.
    The EPA notified Oregon DEQ in a letter dated June 24, 2015 
(adequacy letter), subsequent to the close of the EPA comment period, 
that the EPA had found the MVEBs located in the attainment plan to be 
adequate for use in transportation conformity. A copy of the adequacy 
letter and its enclosure are available in the docket for this action 
and at the EPA's conformity Web site: http://www.epa.gov/otaq/stateresources/transconf/adequacy.htm. The MVEBs that the EPA 
determined to be adequate for purposes of transportation conformity are 
listed in the following table.

         2014 Motor Vehicle Emissions Budgets for Klamath Falls
------------------------------------------------------------------------
 
------------------------------------------------------------------------
PM2.5..................................  699 lbs/day.
NOX....................................  4,834 lbs/day.
------------------------------------------------------------------------

    Transportation conformity is required by section 176(c) of the 
Clean Air Act. Transportation conformity to an attainment plan means 
that on-road transportation activities will not produce new air quality 
violations, worsen existing violations, or delay timely attainment of 
the national ambient air quality standards. The minimum criteria by 
which we determine whether an attainment plan is adequate for 
conformity purposes are specified at 40 CFR 93.118(e)(4). The EPA's 
analysis of how the attainment plan satisfies these criteria is found 
in the adequacy letter and its enclosure.

The EPA's adequacy review is separate from the EPA's attainment plan 
completeness review and it is not dispositive of the EPA's ultimate 
action on the attainment plan.
