te is generated during routine maintenance activities, refueling outages, health physics activities, and radiochemical laboratory activities. The vast majority of mixed waste that is stored at nuclear power plants is chlorinated fluorocarbons (CFCs) and waste oil. Other sources include liquid scintillation fluids, other types of organic materials, and metals, including lead and chromium and aqueous corrosives (NRC 1996). Mixed waste is commonly stored onsite due to the lack of treatment and disposal sites. For this reason, impacts resulting from the chemical hazards and occupational exposures to radioactive material may be somewhat higher than would otherwise be expected. In addition, occupational chemical and radiological exposures may occur during the testing of mixed wastes to determine if the constituents are chemically hazardous. III. REVIEW PROCEDURES Facility owners/operators are required by RCRA regulations to maintain sufficient information to iden- tify their mixed wastes. The information required includes RCRA waste codes for the hazardous com- ponents, the source of the hazardous constituents, a discussion of how the waste was generated, the generation rate and volumes of mixed waste in storage, and any information used to identify mixed wastes or make determinations that the wastes are prohibited by land disposal restrictions. Each owner/ operator is required (under RCRA regulations) to develop a waste minimization plan that identifies proc- ess changes that can be made to reduce or eliminate mixed wastes, methods to minimize the volume of regulated wastes through better segregation of materials, and the substitution of nonhazardous materials. The reviewer should take the following steps to assess the applicant’s plans or capabilities for mixed waste disposal: (1) Ensure that the waste minimization plan includes a schedule for implementation, projections of volume reductions to be achieved, and assumptions that are critical to the accomplishment of
