Mr. Earl E. Emery 8 June 19, 1991 <br />that included a soil cap, fending and institutional <br />controls. <br />Case 4 - On behalf of the respondents, Remcor conducted <br />oversight activities of the II.S. Environmental Protection <br />Agency contractors during the remedial investigation/feasi- <br />bility study and is currently conducting the remedial de- <br />sign (RD) for a CERCLA site in 4ermont. This site involves <br />ground wale: recovery,. stabilization of steep landfill <br />slopes, and capping. Remcor has just completed the instal- <br />latior. of two deep pumping wells and will be conducting the <br />pumpinc test during the first week of June 1991. Following <br />analysts of the pumping test results, Remcor will be con- <br />ducting RD activities for the first of two operable units <br />at this site. <br />• Case 5 - Remcor conducted a turnkey investigation, design, <br />and imalementatian of remedial measures at a formerly used <br />landfill in Ohio. The landfill had been used for disposal <br />of brake shoe linings and the manufacturing process for <br />- them produced a waste Consisting of a high lead content <br />dust as well as grinding that contained asbestos. Remcor's <br />investigation included the excavation of test pits and ia- <br />- stallation of monitoring wells to determine the degree and <br />extent of eont~~ination. Our investigation determined that <br />contamination was captained within the site; however, the <br />Ohio Environmental Protection Agency (OEPA) had placed this <br />site on its state Superfund list. To delist the site, we <br />- ~ worked with the OEPA to develop a closure plan. Through <br />bench-scale testing, Aemcor developed a procedure by which <br />tribasic sodium phosphate would be applied to the ground to <br />. - immobilize the lead contained in the waste. Remcor re- <br />eeived permits from the OEPA to do this work and imple- <br />mented the closure plan. <br />-' • Case 6 - Remcor was awarded the closure of an industrial <br />waste landfill in Connecticut. Wastes in the landfill in- <br />eluded resins, thermosetting materials, thermoplastics, and <br />wastewater treatment residues. The major portions of this <br />multi-phase project included: the excavation of on-site <br />- borrow materials to establish the subgrade for the cap; the <br />installation of a force main; a ZS-foot deep leachate col- <br />lection trench; and construction of a pumphouse to move the <br />leachate through the force main to the client's wastewater <br />. treatment facility. The final activity was the capping of <br />the landfill using an involved multi-layer cap, including a <br />30-mil polyvinyl chloride liner, filter fabric, drainage <br />ret, a second layer of filter fabric, Claymaxm, a 2-foot <br />fill layer, and then seeded topsoil.
