First, EPA determines that the Area has attained the 1997 annual PM2.5 National Ambient Air Quality Standard (NAAQS). This determination of attainment is based upon quality-assured, quality-controlled and certified ambient air monitoring data for the 2008-2010 and 2009-2011 monitoring periods, showing that the Pittsburgh Area has monitored attainment of the 1997 annual PM2.5 NAAQS. In accordance with the EPA's applicable PM2.5 implementation rule, this determination of attainment suspends the requirements for the Area to submit an attainment demonstration and associated reasonably available control measures (RACM), a reasonable further progress (RFP) plan, contingency measures, and other planning State Implementation Plan (SIP) revisions related to the attainment of the standard for so long as the Area continues to attain the 1997 annual PM2.5 NAAQS. EPA also determines, based on quality- assured, quality-controlled, and certified monitoring data for the 2007-2009 monitoring period, that the Area attained the 1997 annual PM2.5 NAAQS by its applicable attainment date of April 5, 2010. These actions are being taken under the Clean Air Act (CAA). ## Source - [Federal Register document](https://www.federalregister.gov/documents/2012/10/12/2012-24782/approval-and-promulgation-of-air-quality-implementation-plans-pennsylvania-pittsburgh-beaver-valley) --- *AI Analytics · CC0 1.0*
