**Facility Note:**  **The data in tab "VI S114 Treated WW May 1 2013" was aggregated by the VI on May 5-8, 2013 from the database submissions to EPA by PVC MACT WG participants.**

Westlake

Westlake Note (2): The M107 VCM data result was an extrapolated value that was lower than the lowest calibration standard value as per the Method. Westlake Note (3): The reported value for "Xylenes (isomers and mixtures)" CAS 1330207 is the higher value of the mp-Xylene and o-Xylene results. Westlake Note (3.1): The reported value for "Xylenes (isomers and mixtures)" CAS 1330207 is the sum of the value of the mp-Xylene and o-Xylene results for W estlake Calvert City KY on January 27, 2013. Westlake Note (4): Hydroquinone sample result rejected due to lack of recovery in the associated LCS.

Axiall PLQ LA VI Note (5): Reported by Axiall as 0 and restated by VI to be Not Found, consistent with Axiall ABD MS. W hen detection limits are not reported, it should be stated as such because zeros will be used in limit calculations for that HAP. Axiall PLQ LA VI Note (6): This is a duplicate sample. Only need to use one of these samples for calculation. Suggest this duplicate not be included in limit calculations for consistency with m30 factor. Axiall PLQ LA VI Note (7): For xylenes, use highest of three reported values in calculation to be consistent with what others have done. Axiall PLQ LA VI Note (8): Reported by Axiall as 0 and restated by VI to be Not Reported. W hen detection limits are not reported, it should be stated as such because zeros will be used in limit calculations for that HAP.

Formosa TX VI Note (9): Reported by Formosa as 0 and restated by VI to be Not Reported. W hen detection limits are not reported, it should be stated as such because zeros will be used in limit calculations for that HAP. Formosa TX VI Note (9.1): VI relocated the J indicator out of the value column and into the Notes column to be consistent with other data reported and to allow calculations to be performed on the estimated value. Shintech Freeport2 TX VI Note (10): Date reported as 1/27/13 by Shintech restated by VI to be 1/24/13 in sequence with surrounding dates.

PolyOne Pedrictown NJ: No sample date was entered for sample header No. 10 cell AG22, Sample header nos. 11,21, & 26 numbers skipped in row22

Dow Midland, MI VI Note (11): Reported by Dow for Dow Method as 0 and restated by VI to be Not Reported. W hen detection limits are not reported, it should be stated as such because zeros will be used in limit calculations for that HAP. Dow Midland, MI 

### VI Note (12): Measured value reported for vinylidene chloride based on Dow method of analysis, not M8260B method. Dow's submission has measurements using both methods on different worksheets. Multiple data points for the same day were averaged together.

Note (1): Based on historical data for gases analyzed 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, estimated concentrations would be reported for Vinyl Bromide. Estimated concentrations are calculated based on the closest Internal Standard.
