Proposed Air Emission Standards For Sewage Sludge Incinerators

The U.S. Environmental Protection Agency (EPA) is proposing to cut emissions of mercury, particle pollution and other airbone pollutants from sewage sludge incinerators under proposed 40 CFR 60.4770 of subpart LLLL and proposed 40 CFR 60.5005 of subpart MMMM. 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.

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