Environmental Protection Agency November 3, 2015 – Federal Register Recent Federal Regulation Documents

Under the Federal Clean Air Act (CAA or Act) the Environmental Protection Agency (EPA) is approving revisions to the Oklahoma State Implementation Plan (SIP) submitted by the State of Oklahoma designee. The revisions are administrative in nature and modify redundant or erroneous text within the SIP. The revisions also incorporate new definitions and the current national ambient air quality standards (NAAQS) for four criteria pollutants; delete a subchapter that addresses motor vehicle pollution control devices; and add requirements for certain incinerators.

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Connecticut. The revision amends Regulations of Connecticut State Agencies (RCSA) section 22a-174-20 to update the requirements for controlling volatile organic compound (VOC) emissions from large aboveground storage tanks. The intended effect of this action is to approve these regulations into the Connecticut SIP. This action is being taken in accordance with the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the North Carolina State Implementation Plan (SIP), submitted by the North Carolina Department of Environment and Natural Resources (DENR), Division of Air Quality (DAQ), on February 5, 2013, and supplemented on July 27, 2015. The submissions pertain to conflict of interest requirements of the Clean Air Act (CAA or Act) and were submitted to satisfy the infrastructure SIP sub- element related to the state board for the 2010 Nitrogen Dioxide (NO2) National Ambient Air Quality Standards (NAAQS), 2010 Sulfur Dioxide (SO2) NAAQS, 2008 8-hour Ozone NAAQS and 2008 Lead NAAQS. The CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA, commonly referred to as an ``infrastructure'' SIP, which includes conflict of interest requirements. EPA is taking final action to approve the portions of North Carolina's 2010 NO2 infrastructure SIP, 2010 SO2 infrastructure SIP, 2008 8-hour ozone infrastructure SIP, and 2008 Lead infrastructure SIP as meeting these State board requirements. EPA is also taking final action to convert conditional approvals related to the state board requirements for the 1997 8-hour ozone NAAQS, and the 1997 Annual Fine Particulate Matter (PM2.5) and 2006 24-hour PM2.5 NAAQS to full approval under the CAA. EPA notes that all other applicable North Carolina infrastructure SIP elements for the above listed NAAQS have been or will be addressed in separate rulemakings.

This final rule, promulgated under the Clean Water Act (CWA), protects public health and the environment from toxic metals and other harmful pollutants, including nutrients, by strengthening the technology-based effluent limitations guidelines and standards (ELGs) for the steam electric power generating industry. Steam electric power plants contribute the greatest amount of all toxic pollutants discharged to surface waters by industrial categories regulated under the CWA. The pollutants discharged by this industry can cause severe health and environmental problems in the form of cancer and non-cancer risks in humans, lowered IQ among children, and deformities and reproductive harm in fish and wildlife. Many of these pollutants, once in the environment, remain there for years. Due to their close proximity to these discharges and relatively high consumption of fish, some minority and low-income communities have greater exposure to, and are therefore at greater risk from, pollutants in steam electric power plant discharges. The final rule establishes the first nationally applicable limits on the amount of toxic metals and other harmful pollutants that steam electric power plants are allowed to discharge in several of their largest sources of wastewater. On an annual basis, the rule reduces the amount of toxic metals, nutrients, and other pollutants that steam electric power plants are allowed to discharge by 1.4 billion pounds; it reduces water withdrawal by 57 billion gallons; and, it has social costs of $480 million and monetized benefits of $451 to $566 million.
