JUNE 21, 2022 - CONSENT AGREEMENT: On November 14 and 15, 2019, the EPA and the SCDHEC conducted a Compliance Evaluation Inspection (CEI) at Respondent's Facility. At the time of the CEI, the EPA determined that the Respondent had been using a solvent mixture of approximately 70% tetrachloroethylene and approximately 30% tributyl phosphate (TBP), in SOLX I, to recover uranium dissolved in nitric acid using a solvent/liquid countercurrent extraction system. The EPA determined that the presence of uranium remaining in the spent mixture from the extraction process caused it to be a low-level radioactive waste and the tetrachloroethylene content caused it to be a hazardous waste. The solvent mixture was classified by EPA as a LLMW. At the time of the CEI, the EPA determined that the Respondent was accumulating spent solvent, in the V-1454 tanks. These tanks were not labeled with the words Hazardous Waste. In addition, at the time of the CEI, the Respondent's Facility had never managed this spent solvent as a characteristic or listed hazardous waste, as the Respondent did not deem the mixture to meet the definition of a hazardous waste, nor the F002 listing. The EPA determined that the Respondent had placed and was storing WCM with the added solvent mixture containing tetrachloroethylene in metal drums within 11 40-foot steel shipping containers called Sealands. At the time of the CEI, the EPA determined that the Respondent had also been placing WCM with the added solvent mixt
