The report is a reference document, describing sampling and analysis methods for measuring the hazardous constituents (as defined in 40 C.F.R., Part 261, Appendix VIII) which might be designated as principal organic hazardous constituents (POHCs) in the various influent and effluent streams of incineration facilities. The methods for these constituents are described in the text. Also included is a concise summary sheet for each recommended method which states the name and number of the method, the types of samples and specific analytes to which the method applies, a brief description of the method, instrument, and operating conditions, and reference(s) to more detailed descriptions of the procedure. Technician-level protocols are thus incorporated by reference, rather than by reproduction in this report. In addition to presenting the methods for sampling and analysis of POHCs at these facilities, information concerning additional sampling and analysis requirements, general strategies for preparing sampling and analysis plans to meet the regulatory requirements, and guidelines for reporting and documentation are discussed.
