FXI33B P. G. Hamner - B3SC September 19, 1975 EPA/tetrachloro-p-dibenzodioxin (TCDD) Attached L. G. Scharpf NlA lis - N1A ' / G. J. Levinskas - A2SC J. S. Metcalf - B2NK G. R. Sido - G4EC D. P. Roman - NlA Attached request from the EPA concerns TCDD levels in 2, 4 , 5T, a phenoxy herbicide. All questions in this area are being handled by our Ag company, but I feel we should scrutinize our chlorinated phenolics as well. My real concern (Sido agrees) is that this is just the tip of the iceburg. It is highly probable that the EPA will expand the 2, 4, 5T study to other materials, such as 2, 4 D, etc. As you know, we presently have a program underway to sell 2, 4 Dichlorophenol to manufacturers who would make 2, 4 D herbicide. Thus, I ask the following: 1) Do any of our chlorinated phenols c< Santophen 1 Solution Santophen 1 Flake Parachloropheno1 2, 4 Dichlorophenol 87% and 97% Pentachlorophenol 2) If so, do we know the types of levels. 3) What is your recommendation as to how we should proceed internal D & P to assure that our products are safe in the TCDD area. Any other comments you have in this area would be welcomed. PGH m a n attachment P. G. Hamner
