EPA is approving a redesignation request and a State Implementation Plan (SIP) revision submitted by the State of West Virginia. This revision requests that EPA redesignate the Weirton nonattainment area (Weirton Area) to attainment for the national ambient air quality standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10), and concurrently requests approval of a limited maintenance plan (LMP) as a revision to the West Virginia State Implementation (SIP). In this action, EPA is approving the State's request to redesignate the area from nonattainment to attainment, as well as approving the LMP for the Weirton Area.
