Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Redesignation of the Scranton/Wilkes-Barre 8-Hour Ozone Nonattainment Area to Attainment and Approval of the Area's Maintenance Plan and 2002 Base Year Inventory

EPA is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania. The Pennsylvania Department of Environmental Protection (PADEP) is requesting that the Scranton/Wilkes-Barre ozone nonattainment Area (or "Area") be redesignated as attainment for the 8-hour ozone ambient air quality standard (NAAQS). The Scranton/Wilkes-Barre Area is composed of Lackawanna, Luzerne, Monroe, and Wyoming Counties. EPA is approving the ozone redesignation request for Scranton/Wilkes-Barre Area. In conjunction with its redesignation request, PADEP submitted a SIP revision consisting of a maintenance plan for Scranton/Wilkes-Barre Area that provides for continued attainment of the 8-hour ozone NAAQS for at least 10 years after redesignation. EPA is approving the 8-hour maintenance plan. PADEP also submitted a 2002 base year inventory for the Scranton/Wilkes-Barre Area, which EPA is approving. In addition, EPA is approving the adequacy determination for the motor vehicle emission budgets (MVEBs) that are identified in the Scranton/Wilkes- Barre Area maintenance plan for purposes of transportation conformity, and is approving those MVEBs. EPA is approving the redesignation request, and the maintenance plan and the 2002 base year emissions inventory as revisions to the Pennsylvania SIP in accordance with the requirements of the Clean Air Act (CAA).
