Résumé
EPA is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the State of Colorado on July 31, 2002, for the purpose of redesignating the Lamar, Colorado and Steamboat Springs, Colorado areas from nonattainment to attainment for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM 10 ) under the 1987 standards. The Governor's submittal, among other things, documents that the Lamar and Steamboat Springs areas have attained the PM 10 national ambient air quality standards (NAAQS), requests redesignation to attainment and includes a maintenance plan for each of the areas demonstrating maintenance of the PM 10 NAAQS for ten years. EPA is approving these redesignation requests and maintenance plans because Colorado has met the applicable requirements of the Clean Air Act (CAA), as amended. Upon the effective date of this approval, the Lamar and Steamboat Springs areas will be designated attainment for the PM 10 NAAQS. This action is being taken under sections 107, 110, and 175A of the Clean Air Act.
