Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Redesignation of the Allentown-Bethlehem-Easton 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 Allentown-Bethlehem-Easton Ozone Nonattainment Area (or also referred to here as the Allentown Area, or simply the Area) be redesignated as attainment for the 8-hour ozone ambient air quality standard (NAAQS). The Allentown-Bethlehem-Easton Area is composed of Carbon, Lehigh, and Northampton Counties. EPA is approving the ozone redesignation request for the Allentown Area. In conjunction with its redesignation request, PADEP submitted a SIP revision consisting of a maintenance plan for the Allentown 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 Allentown 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 Allentown- Bethlehem-Easton Area maintenance plan for purposes of transportation conformity, and is approving those MVEBs. EPA is approving the redesignation request, 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).
