LINE 9 AMMO LAP (MINE)
SITE DESCRIPTION
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 9 is about 9 acres in size and was built in 1942 for use as a production facility and produced mine and mine fuses during the Vietnam War. This Line is in modified caretaker status.
The PA/SI was completed in 1991, and an initial RI was completed in May 1996. The Interim ROD requires the removal of an estimated 469cy of metals-contaminated soil. Remedial design sampling, conducted in 2004, located soil contaminants above action levels.
Approximately 200cy of soil was removed and disposed of at the IDA (IAAP-020) per the ROD.
The Army has determined that the facilities at this Line are excess and will pursue non-ER,A funding for building demolition and debris removal, which is listed as an option in the PBC. Additional evaluation of soil beneath the slabs will be required after the demolition.
CLEANUP STRATEGY
This site is considered Response Complete and requires no further action under the IRP as documented in the Phase 4 Remedial Action Report.
