Significant volumes of mixed low-level waste (MLLW) will be generated as part of the management and remediation of the Hanford Site. The MLLW that is generated as part of the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) process will largely be managed as part of that remediation effort, with disposal likely in the centralized Environmental Restoration Disposal Facility (ERDF). Other unique MLLW streams will be produced as part of the Hanford program to disposition tank wastes, and will include failed equipment (melters) and immobilized low-activity wastes. These disposal operations are in the early planning stages and will likely require development of specialized disposal facilities. This paper will focus on disposal of the more ''routine'' waste streams, those currently stored onsite in permitted Resource Conservation and Recover Act (RCRA) facilities, or those newly-generated MLLW streams requiring management in permitted RCRA facilities. These waste streams typically include RCRA regulated MLLW debris, sludges, soils and solidified liquids. In September 1999, the United States Department of Energy, Richland Operations Office and Fluor Hanford began disposing of Land Disposal Restrictions (LDR) compliant MLLW in a RCRA mixed waste disposal facility at the Hanford Site. This facility, one of two at Hanford, is an integral part of a comprehensive program to treat and dispose of the Hanford inventory of stored MLLW, and may aid the DOE Complex in disposing of its legacy of MLLW. The Final Waste Management Programmatic Environmental Impact Statement (WM PEIS) record-of-decision (ROD) for MLLW identifies Hanford as one of the disposal sites for much of the DOE complex MLLW. A few actions remain to be completed before waste from offsite generators can be shipped to the Hanford Mixed Waste Facilities for disposal. These actions include, but are not limited to, completion of the Hanford Site Solid (Radioactive and Hazardous) Waste Program Environmental Impact Statement (SW EIS), resolving equity issues associated with the receipt of offsite MLLW, and verification that the candidate waste streams meet the Hanford Site Waste Acceptance Criteria (WAC). The ROD for the SW EIS is expected in 2002, equity discussions are ongoing, and waste acceptance criteria are already established and can be used to determine acceptability.
