The Central Facilities Area (CFA) Building 753 (CFA-753) water storage tank was emptied and piping disconnected in approximately 2005. The age (built in 1952) and poor condition of the tank led facility personnel to go to a single tank (CFA-782) storage system. It was determined that CFA-782 had adequate capacity to meet both potable and fire water needs for CFA. Reduction of the CFA footprint is desired and structures that are no longer needed are the most likely candidates for removal. The proposed project would demolish structures CFA-753 and CFA-703 (microwave tower). Heavy equipment including a trackhoe with process head, dump trucks, front end loaders, etc., would be used to take down, sort, and dispose of these structures. In addition, underground concrete water storage tanks (previously filled in with gravel), located directly to the south of CFA-753, need to have void spaces filled-in for safety. Fill material would be clean gravel from an on-Site gravel source (mostly likely, the Monroe Pit.)
