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.
DATES: The public hearing in Sacramento, California will be held on July 19, 2012.
