YARD B AMMO BOX CHIPPER DISPOSAL PIT
SITE DESCRIPTION
The Yard B ammunition box chipper disposal pit has been estimated to measure 120x40x8ft. The pit was used for a three month period sometime between 1972 and 1975. Wastes consisted of shredded ammunition boxes treated with the wood preservative pentachlorophenol (PCP).
Investigations conducted during 1997 have not substantiated the former existence of this site. If this site is ever located it will be investigated.
Bis-2-ethylhexylphthalate has been found in GW.
This site is considered Response Complete and requires no further action under the IRP. USACHPPM Phase II is complete.
This site may need to be reopened for additional sampling to support the no further action determination.
A revised draft OU3 RI/FS was submitted to EPA for review in April 2008 to address groundwater; the recommendation for groundwater is either “No Further Action” or “institutional controls, monitored natural attenuation, and long term monitoring” depending on the selected risk level.
