SEWAGE TREATMENT PLANT/DRYING BEDS

 

SITE DESCRIPTION

This is an active site, therefore it is not eligible for ER,A funds.

The Sewage Treatment Plant (STP) is the facility’s main sewage treatment plant and has been in operation since the early 1940s. The STP handles all the installation-generated sewage except sewage generated at Line 3A, which has its own sewage treatment system.

Since 1982, laundry water from the Contaminated Clothing Laundry has been discharged to the STP. The STP handles domestic wastes, car wash water, laundry facility wastewater, and wastewater from the x-ray processing plant and is about 1 acre in size. Wastewater is treated by an Imhoff tank, trickling filter, clarifier, and sludge drying beds. The treated wastewater goes through a second treatment prior to discharge.

The sludge that is produced from the wastewater treatment process is removed and dewatered on two sludge drying beds. The beds are lined with two feet of sand.

The PA/SI was completed in 1991, the RI was completed in May 1996.

Any future activities will be addressed with non-ER,A funds.

This site requires No Further Action under the IRP and has been transferred to the Compliance Cleanup Program.
