Federal Water Quality Standards Withdrawn For New Jersey, Puerto Rico and San Francisco Bay

EPA is taking final action to amend the federal regulations to withdraw certain human health and aquatic life water quality criteria applicable to waters of New Jersey, Puerto Rico, and California's San Francisco Bay. In 1992, EPA promulgated the National Toxics Rule or NTR to establish numeric water quality criteria for 12 states and two Territories, including New Jersey, Puerto Rico and parts of California. On May 18, 2000, EPA then promulgated a final rule known as the California Toxics Rule or CTR in order to establish numeric water quality criteria for priority toxic pollutants for the State of California that were not previously in the NTR.

These two states and one territory have now adopted, and EPA has approved, water quality criteria for certain pollutants included in the NTR. Because California, New Jersey, and Puerto Rico now have water quality standards that meet the requirements of the Clean Water Act, EPA has determined that the federally promulgated criteria are no longer needed for these pollutants. Therefore EPA is proposing to amend the federal regulations to withdraw those certain criteria applicable to California, New Jersey, and Puerto Rico. The withdrawal of the federally promulgated criteria will enable New Jersey, Puerto Rico, and California to implement their EPA-approved water quality criteria. This final rule is effective on June 3, 2013.

The water quality criteria subject to this action address both freshwater and marine standards and cover a wide range of priority pollutants, including metals, volatile organic chemicals, PAHs, PCBs, pesticides and others EPA has proposed to withdraw only one federal water quality criteria for California - the saltwater aquatic life cyanide criteria for San Francisco Bay. Other criteria for cyanide for waters in California that are currently part of the NTR or CTR will remain unchanged in the federal regulations

Approval of New Jersey 303(d) Impaired Waters Threatened Waters List

U.S. Environmental Protection Agency has approved the 2010 list of waters in New Jersey that are considered either impaired or threatened by pollutants. An impaired water body is one that does not meet federal water quality standards even after pollution controls have been put in place. A threatened water body is one that is expected to become impaired within two years.

The list specifically includes impaired waters for which the development of a Total Maximum Daily Load, or TMDL, is necessary. The TMDL defines the maximum amount of a pollutant that a water body can receive and still meet water quality standards. They are developed by states and approved by the EPA once the agency determines that the budget will allow the water body to achieve water quality standards. In 2010, new pollutants were included for waters in the basins of the Hudson River, the Passaic River, the Raritan River, the Delaware Bay.

The most common pollutants causing impairment in New Jersey water bodies include PCBs (8.33%), dissolved oxygen (8.19%), phosphorus (7.86%), pH (7.62%), and arsenic (6.89%). New Jersey’s 2010 list identifies 2,112 instances in which a pollutant is causing an impairment of a water body that keeps it from supporting its “designated use” for drinking water, swimming and recreation, fishing or other activities specified by the state. The list also notes the most common sources of water pollutants, which include urban/stormwater runoff, combined sewer overflows from systems that capture both domestic sewage and stormwater, and air pollution, including acid rain.

PCB Health Risk Due To Fish Contamination In Donna Reservoir and Canal Superfund Site, Texas

During the week of February 6-12, 2012, representatives from the Environmental Protection Agency (EPA) and the Texas Department of State Health Services (TDSHS) will be in the area of South Alamo, Texas, to speak with residents about the contamination in the Donna Reservoir and Canal. The Donna Reservoir and Canal is an EPA Superfund site located in Hidalgo County in southern Texas just north of the Rio Grande. The site includes the Donna Reservoir, the Donna Main Canal, the West and East Main Canals which extend north from the reservoir, and a series of interconnecting canals.

This effort is being made to provide local residents with information about the health risks of consuming fish taken from the Donna Reservoir and Canal. The possession of contaminated fish taken from the reservoir is prohibited by the TDSHS. The principal pollutants in the reservoir are polychlorinated biphenyls (PCBs). PCBs are a group of synthetic organic chemicals that can cause a number of different harmful effects in humans. The primary risk to human health from PCBs is from suspended sediment in the water and the consumption of contaminated fish. Effects of consumption of contaminated fish may include nausea, vomiting, abdominal pain, skin rashes, acne, and cancer.
