Abstract
The Environmental Protection Agency (EPA) is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania. The revision consists of a second limited maintenance plan for the carbon monoxide (CO) Pittsburgh Area ("the Pittsburgh Area" or "the Area") in Allegheny County, formerly designated as a CO nonattainment area. The maintenance plan ensures maintenance of the CO national ambient air quality standard (NAAQS) in the Pittsburgh Area for a second 10-year period after redesignation of the Area from nonattainment to attainment, through year 2022. EPA is approving these revisions in accordance with the requirements of the Clean Air Act (CAA).
