CHEMICALS i;;tu rf INTEROFFICE / LAKE CHARLES TO W. J. Peard DATE June 13, 1980 FROM P. S. Trew p.rr SUBJECT WTU Dispersion Study The dispersion study of the WTU scrubber stack shows that the maximum ground level concentration of VC, VDC, Tri, and EDC at a wind speed of 1 .0 miles/hour would occur approximately 500 ft. from the stack. scentration of the pollutants exiting the stack is; VC ~ 0.003 ppm B5/dqy), VDC - 0.009 ppm ^5.9 \hs/da^), EDC - 0.04 ppm bs/day), and Tri - 0.01 ppm (ffifSHBs/dajr}. At the point .5QQ_ft. from fhSTfack, the ground level concentration would be VC ^0.01 ppmT, VDC - 0.03 ppm, EDC - 0.16 ppm, and Tri - 0.06 ppm. ~ /ap SL 0731 no
