MMRP Site UXO 6 - Westminster POLB Fill Area

The Westminster POLB Fill Area was used to place 3 to 4 feet of fill that was, in part, excavated from the 7th Street POLB Mitigation Pond (MMRP Site UXO1). The pond area was used from 1944 to 1982 in association with the Primer/Salvage Yard. Prior to the pond’s creation, the site reportedly was used as an Explosive Ordnance Disposal (EOD) demonstration area and a safety demonstration area at an unknown frequency. The site is also known to have buried munitions similar to those stored at the Primer/Salvage Yard.

A Preliminary Site Inspection (similar to a Preliminary Assessment) was completed in December 2008.  A formal Site Inspection was completed in 2011.  Based on the results of the Site Inspection, a Remedial Investigation was recommended for this site.  As part of the RI, surface clearance and geophysical surveys were completed in late 2017.   A geophysical anomalies investigation and soil sampling were also conducted in May 2018 at a 13-acre parcel located in the southwestern corner of the site.  The RI report is scheduled to be completed in late 2018.
