Dear Mr. Marshall:

This letter provides the United States Environmental Protection Agency's (USEPA) comments regarding the Chicago, Illinois Fiscal Year (FY) 2000-2004 Transportation Improvement Program (TIP). The TIP was available for review on the Chicago Area Transportation Study (CATS) web site. Public comments on the TIP were solicited from August 2, 1999 until August 31, 1999.

Our review has concluded that the criteria of the conformity rule have been met. The FY 2000-2004 TIP is a conformity neutral TIP which meets the requirements in Section 93.122(e) of the transportation conformity rule. This section of the conformity rule allows reliance on a previous regional emissions analysis. The FY 2000-2004 TIP relies on the 2020 Transportation Plan conformity determination. Chicago is a severe ozone nonattainment area and the conformity analysis demonstrates conformity to the mobile source emissions budget in the rate of progress plan for the area.

The Illinois Environmental Protection Agency (IEPA) reviewed and commented on the Chicago TIP conformity in a letter dated October 15, 1999. The IEPA participated in the interagency consultation process. The IEPA found that the TIP demonstrated conformity to the State Implementation Plan for the Chicago area.

If you have any questions regarding these comments, please contact
Patricia Morris, of my staff, at (312) 353-8656.

Sincerely yours,


J. Elmer Bortzer, Chief
Regulation Development Section
