Laraway Hazardous Waste/Ground Water Branch WV Division of Water Resources 1201 Greenbrier Street Charleston, WV 25311 PO LYM ER PRODUCTS DEPARTMENT June 5, 1985 CERTIFIED MAIL RETURN RECEIPT REQUESTED Mr. Stephen R. Wassersug, Director Hazardous Waste Management Division U.S. Environmental Protection Agency, Region III 6th and Walnut Streets Philadelphia, Pennsylvania 19106 Re: EPA I.D. No. WVD 04-587 5291 Dear Mr. Wassersug: U.S. EPA SOLID WASTE MANAGEMENT UNIT SURVEY The following comments apply to this survey: The solid waste management units included are those on this site or contiguous to it. This is our understanding based on questions reviewed with Mr. John Potosnak. Records are not available for the early days of plant operation so we have relied on discussions with longer service employees and on aerial photographs. Earliest aerial photos are for 1960 although plant operation started in 1948. One difficult aspect of the survey is providing engineering prints on the solid waste management units. As a -result of process and equipment changes made over the years, drawings do not always accurately reflect the units in place today. The prints provided-- although limited in accuracy--are the most appropriate available. The topographical prints provided are planimetries which are computer-prepared based on a 1983 aerial photo. In our operations many plastics are reused or reworked under conditions which could be interpreted as "recycling." The number of accumulation or storage areas for these plastics on this site is considerable. We consider this reuse as an integral part of the process and have not, as a result, included these locations as solid waste management units in this survey. None of these plastics would be hazardous under RCRA regulations. H Attachment 4 Stephen R- Wassersug, Director- -2- June 5, 1985 I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

Very truly yours, Works Manager HVB:hcw Attachment 0290H Attachment 4 B-4 ANAEROBIC DIGESTION PONDS (CONT'D.) 7?ecla.cJ-e-.cL Releases, S p i l l s , etc. Prior to 1969 the lower river bank level on which the containment basins are located would flood periodically with inundation of the ponds. This has not occurred since installation of the Belleville Dam. When the third basin was constructed, leakage of surfactant was detected to the river which led to relining of the units. The FC-143 surfactant has also been detected in the aquifier at part per billion levels - just above the analytical detection limit. Q255H-2 /6 Attachment 4
