Old Conservation Yard SMWU
This page describes the RCRA (chemical) cleanup of the Old Conservation Yard solid waste management unit (SWMU).
This solid waste management unit (SWMU) includes the historical OCY, a salvage yard and a former fuel tank farm. The OYC was utilized as an open storage area beginning in the 1950s. One acre of the OCY was partially paved as a barrel storage area. The salvage area held materials from DOE facilities, the Plant Services Department, and vehicles throughout its service. A fuel tank farm was installed adjacent to the OCY during the energy crisis in the early 1970’s.
Radiological contamination was discovered and removed from the OCY. In 1993, the Oak Ridge Institute for Science and Education (ORISE) conducted a final verification survey of the area. The California Department of Health Services (DHS) performed verification sampling and concurred with the radiological release of the site in 1995.
Fuel tanks and earthen berms were removed in 1999 and the area was graded. During the RCRA Corrective Action investigation of the salvage area metal debris was removed and surveyed for radiological contamination. No radioactive contamination was detected at the debris.
Additional work under the RCRA Corrective Action is required.
See the OCY history page for additional information on past radiological cleanup.
