Abstract
EPA is granting conditional interim approval of the State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania, for the Pittsburgh-Beaver Valley moderate ozone nonattainment area (the Pittsburgh area), to meet the 15 percent rate- of-progress (the 15% plan), requirements of the Clean Air Act. EPA is granting conditional interim approval because the 15% plan submitted by Pennsylvania for the Pittsburgh area relies on an enhanced motor vehicle inspection and maintenance (I/M) program, for which EPA has granted conditional interim approval. Conditional approval is also merited because EPA is granting conditional approval to the 1990 base year emissions inventory, upon which the 15% plan is dependent. Finally, EPA is conditionally approving the Pittsburgh 1990 (VOC) emission inventory, to allow Pennsylvania up to one year to supply accurate information for certain stationary emissions sources.
