The attached TCLP analytical results show that the soU no longer exhibits the toxicity characteristic for cadinium or silver. Thiokol sampled the soil piles in accordance with its approved sampUng plan. The soil that was treated at the CAMU was excavated from the following designated areas at Thiokol: SWMU #367 #425 #444 Building M-39 M-39 M-19A According to current plans, it appears that the soil will be processed to recover the silver, instead of being disposed of in Thiokol's landfill. Clifton Mining Co., of Alpine, Utah, has agreed to accept the soil and process it at hs plant at Gold Hill, Utah. Thiokol originally planned to have the treated soil processed for metals recovery, and this option for management ofthe soil has been previously approved by the Division. Division staff members JeffVandel and Rob Powers visited the plant at Gold Hill on September H, 1998. The operation is a smaU batch cyanide leaching process. Thiokol has stated that the taiUngs, or process residues, from the first batch processed wiU be sampled to ensure that they do not exhibit the toxicity characteristic prior to final management at Gold HiU. Thiokol has reserved the right to discontinue shipments ofthe soU to Gold HiU if test results indicate that the taUings are a characteristic hazardous waste. The soU wiU be screened at Thiokol and the coarse material (cobbles etc.) wiU be disposed ofat Thiokol's landfiU. The fine material wUl be trucked to the Gold HUl plant. Closure of the CAMU pad wiU be conducted as described in the CAMU Plan. At the conclusion ofthe closure ofthe CAMU, Thiokol will submit a "Corrective Action Report" to the Division. •OCT 15 '96 03:22Pn THIOKOL E-SISE KOL I P.B/G Listing of Results by Sannple |sampl«!0: M-636-1 "^ Test Pa^-ameler MERCURY ARSENIC BARIUM CADMRM CHROMIUM LEAO SELENIUM SILVER IC?
