The Environmental Protection Agency (EPA) is taking final action finding that the Commonwealth of Pennsylvania has not submitted state implementation plans (SIPs) for three nonattainment areas in Berks and Beaver Counties to meet the requirements of the Clean Air Act (CAA) for attaining the 2008 Lead National Ambient Air Quality Standards (NAAQS). Pennsylvania has not yet submitted SIPs for three nonattainment areas--the Lyons and North Reading nonattainment areas in Berks County and the Lower Beaver Valley nonattainment area in Beaver County--that demonstrate how each nonattainment area would attain the 2008 Lead NAAQS as expeditiously as practicable. These plans were due by June 30, 2012. If Pennsylvania has not submitted and the EPA has not approved the required attainment plans for its nonattainment areas by no later than 2 years after the effective date of this finding, the EPA must promulgate a federal implementation plan (FIP) for the affected nonattainment area. In addition, the CAA provides for the imposition of sanctions if the state does not submit the required attainment SIP within specific timeframes.
