[EPA-R10-OAR-2015-0322: FRL-9931-62-Region 10]

Adequacy Determination for the Grants Pass, Oregon Carbon 
Monoxide 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 Grants Pass, Oregon second 10-year 
limited maintenance plan (LMP) for carbon monoxide (CO) is adequate for 
transportation conformity purposes. The LMP was submitted to the EPA by 
the State of Oregon Department of Environmental Quality (ODEQ or the 
State) on April 22, 2015. As a result of our adequacy finding, regional 
emissions analyses will no longer be required as part of the 
transportation conformity demonstrations for CO for the Grants Pass 
area.

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; 
(206) 553-1778; or by email at pepple.karl@epa.gov.

SUPPLEMENTARY INFORMATION: This action provides notice of the EPA's 
adequacy finding regarding the second 10-year CO limited maintenance 
plan (LMP) for the Grants Pass area for purposes of transportation 
conformity. The EPA's finding was made pursuant to the adequacy review 
process for implementation plan submissions delineated at 40 CFR 
93.118(f)(1) under which the EPA reviews the adequacy of a state 
implementation plan (SIP) submission prior to the EPA's final action on 
the implementation plan.
    The State submitted the LMP to the EPA on April 22, 2015. 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 June 3, 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 LMP. There were no adverse comments 
directed at the on-road portion of the LMP.
    Based on our review, the EPA believes it is appropriate to find 
this LMP adequate for use in transportation conformity prior to final 
action on the LMP. The EPA has moved forward with an approval notice 
for the Grants Pass CO LMP. Until that action is final and effective, 
this adequacy finding allows the State to apply the LMP for 
transportation conformity purposes.
    The EPA notified ODEQ in a letter dated June 24, 2015 (adequacy 
letter), subsequent to the close of the EPA comment period, that the 
EPA had found the LMP 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.
    Pursuant to 40 CFR 93.109(e), limited maintenance plans are not 
required to contain on-road motor vehicle emissions budgets. 
Accordingly, as a result of this adequacy finding, regional emissions 
analyses will no longer be required as a part of the transportation 
conformity demonstrations for CO for the Grants Pass area. However, 
other conformity requirements still remain such as consultation (40 CFR 
93.112), transportation control measures (40 CFR 93.113), and project 
level analysis (40 CFR 93.116).
    Transportation conformity is required by section 176(c) of the 
Clean Air Act. Transportation conformity to a SIP 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 a SIP is adequate for conformity purposes are 
specified at 40 CFR 93.118(e)(4). The EPA's analysis of how the LMP 
satisfies these criteria is found in the adequacy letter and its 
enclosure.

    Authority:  42 U.S.C. 7401-767Iq.

    Dated: July 15, 2015.

Regional Administrator, Region 10.
