EPA Air Emissions Testing of MACT Standards for SSI Units by Environmental Source Samplers, Inc.
Environmental Source Samplers, Inc. has recently completed source testing of sewage sludge incineration (SSI) units at municipal facilities in VA, OH, and NY.
The EPA estimates that the new guidelines for air quality testing may impact 204 SSI units currently in operation at municipal facilities throughout the U.S. This rule is one of the many new standards for units that emit pollutants under the MACT (Maximum Achievable Control Technology) Standards, and was enacted under Section 129 of the Clean Air Act.
Sewage Sludge Treatment Plants, typically are regulated under 40 CFR Part 60, Subpart O, as well as 40 CFR Part 61, Subparts C and E. The new source performance standards for these units have been promulgated under Subpart LLLL, and the Emission Guidelines themselves are promulgated under Subpart MMMM. The EPA estimates that of the 204 active SSI units, 155 are currently meeting these emission limits, and forty will need to install one or more air pollution control devices.
ESS published a table of Regulated Pollutants for SSI units that includes the Regulated Pollutant, the unit of measurement for emission limits, and the emission limit itself for both Multiple Hearth (which accounts for over 80% of identified SSI units) and Fluidized Bed Combusters. The table can be found here: http://www.essknowsair-
In order to measure emission rates for the pollutants relevant to SSI units, it is necessary to do an Emissions Sampling Program, or Stack Test, conducted by a qualified and accredited stack testing organization The EPA has reference methods for quantifying emissions for each regulated pollutant, and the testing must be done in accordance with those methods. ESS is an accredited stack testing company with extensive experience in a wide range of EPA Methods, including those specific to SSI units.
