LINE 800 AMMO RENOVATION

 

SITE DESCRIPTION

This site has been merged with IAAP-044 and IAAP-044G due to proximity and for better management and cost collection. Contaminants from these sites mix making it impossible to delineate which site the contaminants originate in.

This site consists of the contamination from past munitions production. Any contamination from current or future activities will be addressed under compliance (non-ER,A funding).

Line 800 is nearly 18 acres in size and has been in operation intermittently since plant inception. From 1943 to present, the primary function of the line was ammunition renovation, where the explosives filler is washed from the projectiles, and 75mm blank salute ammunition was loaded.

Wastes were generated by metal cleaning operations at Line 800, which were identical to the metal cleaning operations at Line 3. Waste sludge from the metal cleaning bath was disposed of at the former Blue Sludge Lagoon at the Inert Disposal Area (IDA) (IAAP-020) from 1979-1980. The Blue Sludge material was moved into Trench 6 at the IDA in January 1997. Prior to having the Line 3 Treatment Facility, untreated metal cleaning effluent was discharged to the ditches at Lines 3 and 800.

The PA/SI was completed in 1991 and found explosives concentrations which exceed cleanup criteria in the NW corner of the site and the area adjacent to the east end of Building 800-04 and lead concentrations in excess of cleanup criteria along the west side of Building 800-191.

The RI work was finished in May 1996. The Interim ROD requires the removal of 1325cy of contaminated soil.

Soil activities for this site will be addressed under IAAP-044 Line 800 Pinkwater Lagoon.  GW activites for this site will be addressed under IAAP-044G Line 800 Pinkwater Lagoon-GW.
