This protocol outlines a generalized approach for the evaluation of hazardous pollutant emissions from refuse thermal processing facilities. Generalized procedures for conducting trace organic sampling, support sampling, and process monitoring activities are presented. It should be emphasized that these procedures may require modification to satisfy the particular requirements of a given test program. The primary hazardous pollutants of interest in these evaluations are tetrachlorodibenzo-p-dioxins (TCDDs). Specific analytical procedures for these compounds are included in the protocol. The primary objective of the evaluation outlined in this protocol is to provide an estimate of the average concentrations of TCDDs emitted from a facility during the test period. To this end, a 3-day sampling program has been specified under the direction of the Environmental Protection Agency Office of Solid Waste (EPA/OSW) to provide a data base similar to that used by federal regulatory agencies in establishing compliance regulations.
