Abstract:  This document presents an Amendment to the ROD for the Environmental Restoration Disposal Facility (ERDF) at the Hanford Site. In 1988 the Hanford Site was added to the NPL in July 1989 as four sites: 1100 Area, 100 Area, 200 Area, and 300 Area. Each of these areas was further divided into operable units. These operable units contain contamination in the form of hazardous waste radioactive/hazardous mixed waste, and other CERCLA hazardous substances. The lead agency for this action is the EPA. The DOE and the State both concur with the Phase III expansion of the ERDF disposal cells and the staging of wastes awaiting treatment prior to disposal. The three agencies participated jointly in the decision and preparation of this document.
 
Remedy:  This ROD Amendment is necessary to support ongoing remediation of the 100 and 200 Areas by providing additional waste disposal capacity. In addition, staging waste at ERDF is considered more protective of human health and the environment (i.e., located further from the Columbia River and groundwater) and provides a more efficient centralized staging location. The staging area is considered necessary at this time as remediation moves into the more heterogeneous waste forms contained in burial grounds. Highly heterogeneous waste forms are more likely to require treatment.
