Adequacy Status of the Greeley, Colorado Carbon Monoxide Revised 
Maintenance Plan for Transportation Conformity Purposes

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 budgets in the Greeley, Colorado 
carbon monoxide (CO) revised maintenance plan, that was submitted by 
the Governor on June 20, 2003, are adequate for conformity purposes. On 
March 2, 1999, the DC Circuit Court ruled that budgets in submitted 
State Implementation Plans (SIPs) cannot be used for conformity 
determinations until EPA has affirmatively found them adequate. As a 
result of our finding, the North Front Range Transportation & Air 
Quality Planning Council, the City of Greeley, the Colorado Department 
of Transportation and the U.S. Department of Transportation are 
required to use the motor vehicle emissions budgets from this submitted 
maintenance plan for future conformity determinations.

DATES: This finding is effective January 20, 2004.

FOR FURTHER INFORMATION CONTACT: Tim Russ, Air & Radiation Program (8P-
AR), United States Environmental Protection Agency, Region 8, 999 18th 
Street, Suite 300, Denver, Colorado 80202-2466, (303) 312-6479. The 
letter documenting our finding is available at EPA's conformity Web 
site: http://www.epa.gov/otaq/transp/conform/adequacy.htm.

SUPPLEMENTARY INFORMATION: Throughout this document wherever ``we'', 
``us'', or ``our'' are used we mean EPA.
    This action is simply an announcement of a finding that we have 
already made. We sent a letter to the Colorado Air Pollution Control 
Division on October 29, 2003, stating that the motor vehicle emissions 
budgets in the submitted Greeley revised CO 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. Our conformity rule requires that transportation plans, 
programs, and projects conform to SIPs and establishes

the criteria and procedures for determining whether or not they do. 
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.
    We've described our process for determining the adequacy of 
submitted SIP budgets in a memo entitled, ``Conformity Guidance on 
Implementation of March 2, 1999 Conformity Court Decision,'' dated May 
14, 1999. We followed this guidance in making our adequacy 
determination.
    For the reader's ease, we have excerpted the motor vehicle emission 
budgets from the Greeley revised CO maintenance plan and they are as 
follows: Interim year budgets; for the years from 2005 through 2009, 
the budget is 63 tons per day of CO, and for the years from 2010 
through 2014, the budget is 62 tons per day of CO. The final year 
budget, for the year 2015 and beyond, is 60 tons per day of CO.

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

    Dated: December 5, 2003.
Patricia D. Hull,
Acting Regional Administrator, Region VIII.
