Vista Chemical Company 15990 North Barker's Landing Road Post Office Box 19029 Houston, Texas 77224 Phone (713) 531-3200 September 27, 1988 Mr. Marcus Smith Sun Polymers, Inc. P. 0. Box 517 Cloud Drive Sunshine, Louisiana 70780 VtSHA Dear Mr. Smith Rick Flammer recently asked me to review your environmental permit with the state of Louisiana in regard to the business we do with Sun Polymers. Based on that review, I would like to know if the potential VCM emissions from the off-grade material you process is a concern in your operations. Although we know the RVCM to be significantly higher than "premium grade" product, we don't have experience in the emissions that might result from processing of these materials. Sincerely, Thomas G. Grumbles, C.I.H. Environmental Quality Manager dlj cc: Rick Flammer WV 000008271
