Recommended Aquatic Life Ambient Water Quality Criterion for Selenium in Freshwater
The Environmental Protection Agency (EPA) is announcing the release of a final updated Clean Water Act (CWA) section 304(a) recommended national chronic aquatic life criterion for the pollutant selenium in fresh water. The final criterion supersedes EPA's 1999 CWA section 304(a) recommended national acute and chronic aquatic life criteria for selenium. The 2016 recommended criterion reflects the latest scientific information, which indicates that selenium toxicity to aquatic life is primarily based on organisms consuming selenium- contaminated food rather than direct exposure to selenium dissolved in water. Draft versions of the criterion underwent public review in 2014 and 2015 and external peer review in 2015. EPA considered all public comments and peer reviewer comments in the development of the 2016 final selenium criterion document. EPA's water quality criterion for selenium provides recommendations to states and tribes authorized to establish water quality standards under the CWA.
Ocean Dumping: Modification of an Ocean Dredged Material Disposal Site Offshore of Charleston, South Carolina
The Environmental Protection Agency (EPA) is proposing to approve a modification of the ocean dredged material disposal site (ODMDS) site offshore of Charleston, South Carolina pursuant to the Marine Protection, Research and Sanctuaries Act, as amended (MPRSA). The primary purpose for the site modification is to serve the long-term need for a location to dispose of material dredged from the Charleston Harbor federal navigation channel, and to provide a location for the disposal of dredged material for persons who have received a permit for such disposal. The modified site will be subject to ongoing monitoring and management to ensure continued protection of the marine environment.
Office of Research and Development; Ambient Air Monitoring Reference and Equivalent Methods: Designation of One New Reference Method and Four New Equivalent Methods
Notice is hereby given that the Environmental Protection Agency (EPA) has designated, in accordance with 40 CFR part 53, one new reference method for measuring concentrations of sulfur dioxide (SO2), four new equivalent methods for measuring concentrations of PM2.5, PM10 and PM10-2.5 in ambient air.
National Emission Standards for Hazardous Air Pollutant Emissions: Petroleum Refinery Sector Amendments
This action amends the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Petroleum Refineries in three respects. First, this action adjusts the compliance date for regulatory requirements that apply at maintenance vents during periods of startup, shutdown, maintenance or inspection for sources constructed or reconstructed on or before June 30, 2014. Second, this action amends the compliance dates for the regulatory requirements that apply during startup, shutdown, or hot standby for fluid catalytic cracking units (FCCU) and startup and shutdown for sulfur recovery units (SRU) constructed or reconstructed on or before June 30, 2014. Finally, this action finalizes technical corrections and clarifications to the NESHAP and the New Source Performance Standards (NSPS) for Petroleum Refineries. These amendments are being finalized in response to new information submitted after these regulatory requirements were promulgated as part of the residual risk and technology review (RTR) rulemaking, which was published on December 1, 2015. This action will have an insignificant effect on emissions reductions and costs.
