SITE DESCRIPTION

The KB Alloys Site is an aluminum master alloy production operation. A Phase I Environmental Assessment conducted at the site in 1989 determined that polychlorinated biphenyl (PCB) containing capacitors at the site had released PCBs inside the facility.  Several steps were taken to remediate PCB-containing materials in the facility.  A small amount of PCB-contaminated soil was detected below the concrete surface.  This soil could not be removed without risking structural damage to the facility.  In addition, a small amount of contamination remained ingrained in areas of concrete that could not be removed without risking structural damage to the facility.  Following remedial actions, a new layer of surface concrete was placed in the cleanup area and the cleaned and sandblasted surfaces were sealed and repainted.  All materials removed as part of this remedial action were disposed of as PCB-containing waste.  It was determined that these remedial activities were protective of groundwater and of human health.  No further remedial actions were required at the site.
