An initial laboratory and field evaluation study has been completed which assessed the performance of the Semi-Volatile Organic Sampling Train Method (Semi-VOST) for measuring concentrations of principal organic hazardous constituents (POHCs) with boiling points greater than 100C that are emitted from hazardous waste incinerators. A draft formulation of the methodology was tested through an experimental laboratory program to evaluate method performance characteristics. The program consisted of: (1) determination of minimum compound detection limits; (2) simulation of a flue gas stream to determine the impacts of water vapor, SO2, NOx, and HCl on sampling; and (3) determination of precision and bias for the sample preparation and analytical elements of the method. Results of the simulation study are reported for 12 test compounds (POHCs) representing a range of physical and chemical properties which could affect sample train collection and recovery performance. Three of the test compounds were selected for further investigation to evaluate method precision and bias under field conditions through the use of four simultaneously-operating Semi-VOST trains. Project results are presented in Volume I along with recommendations on elements of the method requiring further research. Volume II includes appendices giving detailed descriptions of the method formulation, laboratory, and field studies along with quality assurance data.
