Start Preamble

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.

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 Start Printed Page 340the 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.
