Dear Mr. Steger:

The United States Environmental Protection Agency (USEPA) has completed its review of fiscal year 2000-2002 Transportation Improvement Programs (TIP) for the St. Cloud and Duluth/Superior metropolitan areas. These TIPs were prepared by the St. Cloud Area Planning Organization (APO) and the Metropolitan Interstate Committee (MIC), respectively, in coordination with the Minnesota Department of Transportation. This letter provides the results of our review of the APO and MIC TIP conformity determinations.

The St. Cloud and Duluth/Superior metropolitan areas, are currently designated maintenance for carbon monoxide (CO). It was determined through the interagency consultation process that the CO problem for these areas was localized in nature and air quality modeling should be performed on a hot-spot basis. It appears all of the non exempt projects are not at the point in the design process where hot-spot analysis can be performed. Therefore, it is important that these projects continue to be tracked through the interagency consultation process so that air quality modeling will be performed when appropriate to assure that the CO air quality standard will be maintained.

The Minnesota Pollution Control Agency, the State air quality agency, has reviewed the APO and MIC TIPs and concurs that the conformity determinations are consistent with the State Implementation Plan.

If you have any questions, feel free to contact Michael Leslie, of my staff, at (312) 353-6680.

Sincerely yours,

Loretta Lehrman for

Stephen Rothblatt, Chief
Air Programs Branch
