GPO FDSys XML | Text type regulations.gov FR Doc. 2012-16045 RIN EPA-HQ-OAR-2007-0492 FRL-9694-8 ENVIRONMENTAL PROTECTION AGENCY Announcement of public hearings. The public hearings will be held on July 17, 2012, in Philadelphia, Pennsylvania, and on July 19, 2012, in Sacramento, California. Please refer to SUPPLEMENTARY INFORMATION for additional information on the public hearings. 40 CFR Parts 50, 51, 52, 53, and 58 The EPA is announcing two public hearings for the proposed rule titled, “National Ambient Air Quality Standards for Particulate Matter,” that is scheduled to be published in the Federal Register on June 29, 2012. The hearings will be held in Philadelphia, Pennsylvania, and Sacramento, California. In this rulemaking, the EPA is proposing to make revisions to the primary and secondary national ambient air quality standards (NAAQS) for particulate matter (PM) to provide requisite protection of public health and welfare, respectively, and to make corresponding revisions to the data handling conventions for PM and ambient air monitoring, reporting, and network design requirements. The EPA is proposing changes to the Air Quality Index (AQI) to be consistent with the proposed primary standards. In addition, the EPA is proposing revisions to the prevention of significant deterioration (PSD) permitting program with respect to the proposed NAAQS revisions.
