New Rule Proposed for Emissions from Sewage Sludge Incinerators

Wednesday, October 27th, 2010

Sewage Sludge IncineratorThe EPA has proposed new rules directed at emissions from sewage sludge incinerator (SSI) units. SSI units are typically found at wastewater treatment facilities and, according to the EPA, are the sixth-largest source of mercury air emissions in the US. The proposal not only limits mercury emissions, but also sets standard and emission guidelines for eight other pollutants, including lead, cadmium, hydrogen chloride, particulate matter, carbon monoxide, dioxins and furans, nitrogen oxide, and sulfur dioxide. However, mercury is of particular interest because the proposed emission standard is more stringent than the mandates that were set under the Clean Air Act.

Proposed Rules and Standards Affecting Air Emissions

Monday, June 7th, 2010

Proposed Rules and Standards Affecting Air EmissionsOn April 29, 2010, the EPA announced two proposed air toxics standards: (1) an amendment to emission guidelines and new source performance standards, and (2) proposed new rules to clearly define and identify solid and non-solid, non-hazardous secondary materials.

The two air toxic standards will affect emissions from industrial, commercial, and institutional boilers and process heaters. One is written for major source facilities, which are those that emit or have the potential to emit 10 or more tons per year of any single air toxin or over 25 tons per year of any combination of air toxins. The second is for area source facilities that emit less than 10 tons per years of a single air toxin or less than 25 tons of any combination.
