Audit materials containing Principal Organic Hazardous Constituents (POHCs) have been developed by EPA for use by Federal, State, and Local agencies or their contractors to assess the accuracy of measurement methods used during RCRA trial burn tests. Audit materials are currently available for 27 gaseous organics in five-, six-, and seven-, and nine-component mixtures at ppb levels (7 to 10,000 ppb) in compressed gas cylinders in a balance gas of nitrogen. The logic used in selecting 27 gaseous organic compounds as audit materials and how these audit materials are successfully used in performance audits is described. Stability studies indicate that all of the organics tested (with the exception of ethylene oxide and propylene oxide below 10 ppb levels) are stable enough to be used as reliable audit materials. As of January 1990, 215 performance audits have been conducted to assess the accuracy of Volatile Organic Sampling Train (VOST) and bag measurement methods during or prior to RCRA trial burn tests. A summary of the audits conducted for each POHC, the measurement system audited, and the frequency of audits is described. The audit results obtained with audit gases are generally within {plus minus}50% of the audit concentrations.
