Abstract
EPA is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania. The revision amends Pennsylvania's ten-year plan to maintain the 1-hour ozone national ambient air quality standard (NAAQS) in the Pittsburgh-Beaver Valley ozone maintenance area (the Pittsburgh area). The maintenance plan is being amended to revise the volatile organic compound (VOC) and nitrogen oxides (NO<INF>X</INF>) motor vehicle emission budgets (MVEBs) to reflect the use of MOBILE6. The intended effect of this action is to approve a SIP revision that will better enable the Commonwealth of Pennsylvania to maintain attainment of the 1-hour ozone NAAQS in the Pittsburgh area. This action is being taken in accordance with the requirements of the Clean Air Act.
