Bordeaux mixture was formerly produced but has been discontinued. All products are formulated on a batch basis. Process wastewaters are treated onsite and batch discharged through a single permitted outfall (Outfall 001) to the Kanawha River. On August 28, 1979, Environmental Protection Agency (EPA) Region III requested that the National Enforcement Investigations Center (NEIC) investigate Chemical Formulators. The Company is under a State consent decree which requires remedial actions regarding wastewater treatment and contaminated liquids on plant grounds. The request was initizated, in part, because of continuing Federal and State concern about hazardous waste handling and disposal practices at this facility. During December 11 through 14, 1979, and on February 19, 1980, NEIC personnel investigate Chemical Formulations to determine compliance with applicable State and Federal regulations. The primary objectives were to evaluate: (a) waste disposal practices, (b) the potential for offsite hazards resulting from these practices, and (c) possible environmental impacts.
