Mercury Cutting Proposal targets sewage sludge incinerators.

Press Release Summary:



EPA proposes to cut emissions of mercury, particle pollution, and other harmful pollutants from sewage sludge incinerators. Proposed standards, applicable to both multiple hearth and fluidized bed incinerators, would cut mercury emissions from these units by over 75%. By EPA estimates, proposal would yield health benefits ranging from $130-$320 million in 2015. Estimated annualized cost to comply with proposal standards for all currently operating units is estimated at $105 million.

EPA Proposes to Cut Mercury Emissions from Sewage Sludge Incinerators



WASHINGTON - The U.S. Environmental Protection Agency (EPA) is proposing to cut emissions of mercury, particle pollution and other harmful pollutants from sewage sludge incinerators, the sixth-largest source of mercury air emissions in the United States. Mercury can damage children's developing brains, and particle pollution is linked to a variety of serious health effects, including aggravated asthma, heart attacks and premature death in people with heart and lung disease.

Sewage sludge incinerators are typically located at wastewater treatment facilities. The proposed standards would apply to both multiple hearth and fluidized bed incinerators. Units incinerating sewage sludge at other types of facilities such as commercial, industrial and institutional incinerators will be covered under different air pollution standards. Overall, the proposal would cut mercury emissions from these units by more than 75 percent.

Mercury in the air eventually deposits into water, where it changes into methylmercury, a highly toxic form that builds up in fish. People are primarily exposed to mercury by eating contaminated fish. Because the developing fetus is the most sensitive to the toxic effects of methylmercury, women of childbearing age and children are regarded as the populations of greatest concern.

EPA estimates that the proposal would yield health benefits ranging from $130 million to $320 million in 2015, with annualized costs estimated at approximately $105 million for all currently operating units to comply with the proposal standards.

EPA will take comment on the proposed rule for 30 days after it is published in the Federal Register. The rule will be finalized in 2011 and become effective in 2015.
