* ! Ur. R. E. Garber cc: J. Weber M. Glenn J. Wetzel R. W. Laundrle May 22, 1974 SPI Meeting at Saddle Brook, Rev Jersey,fon Air EatLssl ns of VCM and ERA The purpose of this meting was to exchange lnfomatlon vlth other VC and FVC producers on the control of VC emissions from the plants and to establish the EPA activity in the field. ,-v- n4-r In general, all concerned seem to have concluded that to decrease the pcehlept of the users of PVC resins, the VC oust be decreased at the FVC mnuaet^^flj| V' plants. . Some approaches being looked at are: 1. Oxidation of VC* 2. Scavenging agents for VC. 3. Polymerization of gC. 4. Solvent absorption. 5* Carbon black adsorption. 6. Better stripping procedures. The concensus u that for political reasons, the EPA would set emission standards that would yield at die plant perimeter limits a level of VC the same as that finally adopted by 06BA for the environment of the workers. The State of Texas has decreed that VC emissions must be reduced from where they are pfri) tb 801 of prgpsnt level by 1976 end by 901 by 1978. :-r\ Diamond is Tggig"-tPUtg-fMBc) finds 1.3 to 2.0 ppm of VC one-half adle from plant.
