As directed by the U.S. Department of Energy, Richland Operations Office, Fluor Hanford, Inc. will implement the requirements of U.S. Department of Energy Order 435.1, Radioactive Waste Management, as these requirements relate to the continued operation of the low-level waste disposal facilities on the Hanford Site. U.S. Department of Energy Order 435.1 requires a disposal authorization statement for continued operation of existing low-level waste disposal facilities. Conditional authorization to transfer, receive, possess, and dispose of low-level radioactive waste at the 200 East Area and the 200 West Area Low-Level Burial Grounds on the Hanford Site was issued on October 25, 1999. One condition was that a performance monitoring plan for these disposal facilities be written and approved by the U.S. Department of Energy, Richland Operations Office. In response to this requirement, Fluor Hanford, Inc. contracted with the Pacific Northwest National Laboratory to prepare this plan.
