Environmental Protection Agency September 2, 2014 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Arizona State Implementation Plan (SIP) concerning 2008 and 2010 emissions inventories for the 2006 24-hour fine particle (PM2.5) National Ambient Air Quality Standard (NAAQS) for the Nogales PM2.5 nonattainment area. We are approving these annual emissions inventories under the Clean Air Act (CAA or the Act).

EPA is finalizing significant new use rules (SNURs) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for 36 chemical substances which were the subject of premanufacture notices (PMNs). Seventeen of these chemical substances are subject to TSCA section 5(e) consent orders issued by EPA. This action requires persons who intend to manufacture or process any of these 36 chemical substances for an activity that is designated as a significant new use by this final rule to notify EPA at least 90 days before commencing that activity. The required notification provides EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.

The Environmental Protection Agency (EPA) is finding that the North Coast Air Quality Management District (NCAQMD or District), located in California, has not made a necessary Prevention of Significant Deterioration (PSD) State Implementation Plan (SIP) submission to address the PSD permitting of PM2.5 emissions, as required by the Clean Air Act (CAA). Specifically, the EPA is determining that NCAQMD has not submitted a SIP revision to address the PM2.5 PSD increments and implementing regulations as promulgated by EPA on October 20, 2010. The deadline for the District to make the required submittal was July 20, 2012. The CAA requires EPA to promulgate a Federal Implementation Plan (FIP) to address the outstanding PSD SIP elements by no later than 24 months after the effective date of this finding. EPA is making this finding in accordance with section 110 and part C of the CAA.
