Adequacy Determination for the Salt Lake City Area Carbon 
Monoxide Maintenance State Implementation Plan for Transportation 
Conformity Purposes; State of Utah

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of adequacy.

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

SUMMARY: In this document, EPA is notifying the public that we have 
found that the motor vehicle emissions budget for 2019 in the Salt Lake 
City, Utah Carbon Monoxide Maintenance Plan, that was submitted by Utah 
Governor Olene S. Walker on October 19, 2004, is adequate for 
transportation conformity purposes. 40 CFR 93.118(e)(2) requires that 
EPA declare an implenatation plan submission's motor vehicle emissions 
budget adequate for conformity purposes prior to the budget being used 
to satisfy the conformity requirements of 40 CFR 93. As a result of our 
finding, the Wasatch Front Regional Council of Government, the Utah 
Department of Transportation and the U.S. Department of Transportation 
are required to use the motor vehicle emissions budget from this 
submitted maintenance plan for future transportation conformity 
determinations.

DATES: This finding is effective June 15, 2005.

    The letter documenting our finding is available at EPA's conformity 
Web site: http://www.epa.gov/transp/conform/adequacy.htm.

SUPPLEMENTARY INFORMATION: Throughout this document ``we'', ``us'', or 
``our'' are used to mean EPA.
    This action is simply an announcement of a finding that we have 
already made. We sent a letter to the Utah Division of Air Quality on 
May 2, 2005, stating that the motor vehicle emissions budgets in the 
submitted Salt Lake City, Utah Carbon Monoxide Maintenance Plan are 
adequate. This finding has also been announced on our conformity Web 
site at http://www.epa.gov/otaq/transp/conform/adequacy.htm.
    Transportation conformity is required by section 176(c) of the 
Clean Air Act. Out conformity rule requires that transportation plans, 
programs, and projects conform to SIPs and establishes the criteria and 
procedures for determining whether or not they demonstrate conformity. 
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). Please note that an adequacy review is separate 
from our completeness review, and it also should not be used to 
prejudge our ultimate approval of the SIP. Even if we find a budget 
adequate, the SIP could later be disapproved, and vice versa.
    The process for determining the adequacy of a transportation 
conformity budget is described at 40 CFR 93.118(f).
    For the reader's ease, we have excerpted the motor vehicle emission 
budget from the Salt Lake City, Utah Carbon Monoxide Maintenance Plan 
it is as follows: Motor vehicle emissions budget for the year 2019 is 
278.62 tons per day of CO. 40 CFR 93.118(e)(1) requires that previously 
approved budget for years other than 2019 must still be used in any 
conformity determination until the maintenance plan is fully approved 
by EPA.

    Authority: 42 U.S.C. 7401 et seq.
