Perimeter Sampling for VCM at the Henry Plant - Status Report No. 2
DATE THIS UTTTER
8/2/74
Introduction:
The purpose of this study is to determine the vinyl chloride monomer (VCM) concentrations at the perimeter of the Henry Plant. Samples were taken upwind and downwind of the Poly Vinyl Chloride Production Building, the main source of VCM concern. The samples were taken on 13 separate days and analyzed by gas chromatography.
Conclusion:
The new syringes used with the previous technique showed low concen trations of VCM at the plant's perimeter. The following concentrations were found:
Upwind - 0.11 ppm Downwind - 0.48 ppm
Discussion:
13 days 13 days
range 0 - .33 ppm range 0 - 2.41 ppm
The sample locations varied with wind direction but a general pattern was used. Sample 1 was taken directly upwind of the PVC Building. Samples 2, 3, and 4 were taken downwind of the Building, one point directly downwind and the other points to each side of the directly downwind sample. Wind speeds were also recorded for each sample using an Alnor Velometer. (For detailed locations, see attached maps).
The standard for concentration comparisons was a cylinder containing 23.5 ppm VCM. The standards for comparison with ambient samples were run on each day, since gas chromatograph changes slightly from day to day. The samples and standards were run on a Hewlett Packard gas chro matograph with flame ionization detection. The column used was a 2* x 1/8" Poropak QS Type, 80/100 mesh. Column temperature was 140C. Area counts and concentration calculations were arrived at by using an Auto-Lab System I Integrator. Sample sizes were all 1 milliliter. The syringe was heated, evacuated and cooled before each new samples was run.

Future Action:
The method seems good. The sampling will continue. An effort will be made to obtain data under unusual operating conditions, e.g., when a poly is being vented out the roof.
