Homan 7 ** */ As a result of our surprise findings of dioxins ..in the retained sample of the "Sturgeon OCP/C tankcar," I under stand we are now going to analyze additional OCP/C samples to determine if dioxins/TCDD is typical. While we are doing this test, should we not go one step further and analyze again for dioxins in POP and 2,4 DCP (and possibly SANTOPHEN I if PCP shows dioxins)? I am concerned that^in our first look for dioxins in OCP/C about a yea^ v p Tfound Basically .juJne^and now we are finding about 800 ppra of which some is the TCDD. This probably will not be a serious issue with our OCP/C customers (EPA???) since they are familiar with dioxins plus when they further chlorinate the OCP/C the TCDD will disappear. But, I am afraid this is not the case with our PCP/2,4 DCP/S-I customers and the reaction could be detri mental to our business from a sales/environmental standpoint. Therefore, I recommend we take another look at our entire chlorophenol complex to avoid another surprise and also to mg C 003S 2
