Abstract
EPA is approving a request for Pennsylvania to redesignate the Liberty Borough area of Allegheny County, Pennsylvania (the Liberty Borough area) from nonattainment to attainment for the national ambient air quality standard (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 microns (PM<INF>10</INF>). EPA is also approving a maintenance plan for the Liberty Borough area. Both the redesignation request and maintenance plan were submitted by the Pennsylvania Department of Environmental Protection (PADEP) on behalf of the Allegheny County Health Department (ACHD). Approval of the maintenance plan, as a revision to the Pennsylvania State Implementation Plan (SIP), puts a plan in place for maintaining the PM<INF>10</INF> standard for the next ten years in the Liberty Borough area. This action is being taken in accordance with the Clean Air Act (CAA).
