## Abstract

On September 22, 1997, the Governor of the State of Colorado submitted a State Implementation Plan (SIP) revision for the purpose of establishing a redesignation for the Canon City, Colorado area from nonattainment to attainment for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 microns (PM<INF>10</INF>) under the 1987 standards. The Colorado Air Pollution Control Division's (Colorado) submittal, among other things, documents that the Canon City area has attained the PM<INF>10</INF> national ambient air quality standards (NAAQS), requests redesignation to attainment and includes a maintenance plan for the area demonstrating maintenance of the PM<INF>10</INF> NAAQS for ten years. EPA is approving the redesignation request and maintenance plan because the State has met the applicable requirements of the Clean Air Act, as amended. Subsequent to this approval, the Canon City area will be designated attainment for the PM<INF>10</INF> NAAQS. This action is being taken under sections 107, 110, and 175A of the Clean Air Act (Act).
