Northwest Pipe and Casing Company-Hall Process Company

Site Summary
    Northwest Pipe and Casing in Clackamas, Oregon was the location of pipe manufacturing and coating operations from 1956 to 1985. Waste from the facility contaminated the soil and groundwater with solvents, primers, coal tar, coal-tar residues, polychlorinated biphenyls (PCBs), and oils.

    The site was added to EPA’s National Priorities List 1992. The following year, the buildings were demolished and a fence was constructed to keep people away from the site. In 1998, two underground fuel tanks were decommissioned and removed from the site. In 1999, security patrols were started to keep trespassers off the site. Following a comprehensive study, EPA issued a groundwater cleanup plan in 2001 and a soil cleanup plan in 2000.

    In 2006, five-year review of the site found that human health and the environment were currently protected, but EPA needs to modify the cleanup plan to make sure that the remedy for groundwater contamination continues to protect people and wildlife in the future.
