Clean-up Overview The cleanup will consist of collectiny non-radioactive debris and explosive ordnance, radioactively contaminated debris, and plutonium contaminated soil. Estimates by DNA for the volume of soil that must be dealt with range from 70-200,000 cubic yards. Non-contaminated debris will be dumped in the lagoon. Contaminated debris and soil will be placed in and adjacent to one (or both) craters at the north end of Runit Island. A concrete cap will be constructed over the relocated debris. General guidance for removal of contaminated soil was provided by an AEC Task Group in June 1974. The detailed clean-up concept is set forth in the DNA Environmental Impact Statement of April 1975. The Clean-up Plan, including a description of ERSP participation is set forth in DNA OPLAN 600-77. The NV project management organization and concept of operations is outlined in :NV memo of February 23, 1977. (copy enclosed) DOE support operations got underway in FY 1977 and are expected to continue into FY 1980. The DOD/DOE phase of the project (the cleanup and certification) is expected to come to an end in FY 1980, when demobilization will occur. BOOK PAGE:
