Stafford Mr. C. H. Oreenert Dr. R. E. Pleven Mr. R. N. Wheeler ^ Subject: Interpretation of Vinyl Chloride Regulation Dlover: Enclosed is a copy of the letter received from the BPA regarding our questions submitted to Ur. Seid last December. The answers appear very encouraging and we should be able to establish a "standard procedure", gather supporting data and then apply for alternate test methods for both of our areas of concern. As discussed with you on the phone, I believe the so ner we can get back to the EPA with our proposal to bum the VC vent stream in the Olefin Furnaces, the better off we will be. In my opinion, the key points will be: a compliance schedule better then the one presented, the flame temperature, proper mixing of the vent stream in the burner and an emission monitoring system. The monitoring system could be a difficult point since the stack gas would probably be less then 10 ppm simply by the tremendous dilution involved. Perhaps monitoring of the furnace temperature would be an acceptable alternative method. ... _ ___. Please call on me if I can help in any way* ,Very truly yours, KGM/kjm }^ * V - -/rf'" te* '\ C.
