EXPLOSIVE WASTE INCINERATOR

 

SITE DESCRIPTION

The Explosive Waste Incinerator (EWI) was located in the southwest corner of the Explosive Disposal Area (IAAP-012). The EWI contained an adjoining air pollution control system. The site treated explosive wastes, sump scrap, and explosives-contaminated waste solvents. Explosives-contaminated carbon was originally treated in the EWI, but is now recycled. Resultant ash was collected and managed as a hazardous waste. The EWI site underwent RCRA closure, and the incinerator was removed from the installation in 1999.

The PA/SI was completed in 1991, and an initial RI was completed in May 1996. One area (drainage ditch) had a detection of RDX at levels above cleanup criteria.

Additional soil and sediment samples were collected in 2004 by MKM and documented in the Draft Final Report for the Soil Data Collection.  No analytes above the background levels as determined in the OU1 Record of Decision were detected. 

A draft final (rev. 1) OU-4 supplemental RI was submitted to EPA for review in July 2008 and is currently in “informal dispute”.     

 

A revised draft OU-3 RI/FS was submitted to EPA for review in April 2008.

 

CLEANUP STRATEGY 

 

This site is included in the PBC awarded in 2004.

 

The IRP will be responsible for groundwater and soil contamination.  The recommendation for the soils and the groundwater is No Further Action as documented in the draft final (rev. 1) OU-4 supplemental RI and the revised draft OU3 RI/FS.
