## Abstract

EPA is approving revisions to the Allegheny County portion of the Commonwealth of Pennsylvania State Implementation Plan (SIP). These revisions were submitted on March 23, 2000 by the Pennsylvania Department of Environmental Protection (PADEP) on behalf of the Allegheny County Health Department (ACHD). These revisions amend Allegheny County's general rules for use of cleaner gasoline and codify changes to its gasoline volatility regulations to be consistent with the Commonwealth's SIP-approved regulations which currently apply throughout the Pittsburgh-Beaver Valley ozone nonattainment area, including in Allegheny County. The revisions consist of the establishment of a Reid vapor pressure (RVP) limit of 7.8 pounds per square inch (psi) for gasoline sold in Allegheny County, Pennsylvania. EPA is approving these revisions to the Allegheny County portion of the Commonwealth of Pennsylvania SIP in accordance with the requirements of the Clean Air Act.
