1. Complete the table below for each PVC process wastewater steam exiting a process wastewater treatment system that was sampled and analyzed. Com plete one worksheet for each single stream (make copies of this worksheet if necessary). 2. Enter the PVC process wastewater treatment system ID for the stream that was sampled and analyzed. The ID must match the IDs listed in Table 2 of the "Stream Info" worksheet. 3. Complete columns 1 through 30. Enter the sample date, resin type, stream flow rate, basis for flow rate determination, stream temperature, sample type, analysis date, lab report ID, and lab sample ID. Enter the concentration results for each HAP listed. 4. Enter any

other HAP expected to be present (that are not listed in Table 10 to Subpart HHHHHHH of Part 63) in the table below. 4. For compounds that were not detected, indicate as such in the "Non-Detect?" column and provide the method detection limit, in ppmw, in the "Concentration (ppmw)" column. 5. Enter any

Note (1): Based on historical data for gases analy zed by SW-846 Method 8260B (SW-5030B Purge and Trap), the method quantitation limit (MQL) for Vinyl Bromide is estimated to be 1 ug/L. Due to the fact that calibration standards and verification standards were not readily available, estim ated concentrations would be reported for Vinyl Bromide. Estimated concentrations are calculated based on the closest Internal Standard. Note (2): The M107 VCM data result was an extrapolated value that was lower than the lowest calibration standard value as per the Method. Note (3): The reported value for "Xylenes (isomers and mixtures)" CAS 1330207 is the higher value of the mp-Xylene and o-Xylene results. Note (4): Hydroquinone sample result rejected due to lack of recovery in the associated LCS.
