Office of Research and Development; Ambient Air Monitoring Reference and Equivalent Methods: Designation of a New Reference Method
Notice is hereby given that the Environmental Protection Agency (EPA) has designated, in accordance with 40 CFR Part 53, a new reference method for measuring mass concentrations of coarse particulate matter (PM10-2.5) in the ambient air.
CERCLA/EPCRA Administrative Reporting Exemption for Air Releases of Hazardous Substances From Animal Waste at Farms
This final rule provides an administrative reporting exemption from particular notification requirements under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended. In addition, this final rule provides a limited administrative reporting exemption in certain cases from requirements under the Emergency Planning and Community Right-to-Know Act, also known as Title III of the Superfund Amendments and Reauthorization Act. Specifically, the administrative reporting exemption applies to releases of hazardous substances to the air that meet or exceed their reportable quantity where the source of those hazardous substances is animal waste at farms. Nothing in this final rule changes the notification requirements if hazardous substances are released to the air from any source other than animal waste at farms (e.g., ammonia tanks), or if any hazardous substances from animal waste are released to any other environmental media, (e.g., soil, ground water, or surface water) when the release of those hazardous substances is at or above its reportable quantity. Also, the administrative reporting exemption under section 103 of the Comprehensive Environmental Response, Compensation, and Liability Act, does not limit any of the Agency's other authorities under the Comprehensive Environmental Response, Compensation, and Liability Act sections 104 (response authorities), 106 (abatement actions), 107 (liability), or any other provisions of the Comprehensive Emergency Response, Compensation, and Liability Act or the Emergency Planning and Community Right to Know Act. Accordingly, EPA believes this administrative reporting exemption not only leaves in place important Agency response authorities that can be used to protect human health and the environment if needed, but also is consistent with the Agency's goal to reduce reporting burden, particularly considering that Federal, State or local response officials are unlikely to respond to notifications of air releases of hazardous substances from animal waste at farms.
Revisions to the California State Implementation Plan, South Coast Air Quality Management District
EPA is finalizing approval of revisions to the South Coast Air Quality Management District portion of the California State Implementation Plan (SIP). These revisions were proposed in the Federal Register on July 24, 2008 and concern the District's analysis of whether its rules met reasonably available control technology (RACT) under the 8-hour ozone National Ambient Air Quality Standards (NAAQS). We are approving the analysis under the Clean Air Act as amended in 1990 (CAA or the Act).
