Unidynamics/Phoenix, Inc. to pay
for brownfields cleanups
Unidynamics/Phoenix, Inc. and its parent company,
Crane Co., have agreed to a settlement for the Phoenix-Goodyear
Airport North Superfund Site. The potentially responsible parties
will pay over $8 million and complete site work. The settlement
requires the parties to continue the current cleanup efforts, conduct
supplemental site investigation, pay EPA $6.7 million for past costs,
and pay future cleanup costs. They will also pay $500,000 in penalties
for failing to complete some required cleanup work.
The parties have also agreed to complete a supplemental
environmental project that will encourage redevelopment in Goodyear,
the city most impacted by the site contamination. The companies
will create an inventory of and assess up to 25 potential brownfields
sites in the city. From the compiled list of available sites, the
city and residents will select four sites for more extensive site
assessments, and the settling parties will complete cleanup at three
sites. The parties are required to spend no less than $1 million
on inventorying and remediating the selected sites.
From 1963 until 1994, the Unidynamics/Phoenix,
Inc. facility was used to manufacture defense and aerospace component
systems, including pyrotechnics and explosives. Until 1980, most
wastes generated by the facility were disposed of in 11 dry wells
and 2 unlined oxidation ponds. Site soils and groundwater are contaminated
with volatile organic compounds (including trichloroethylene) and
perchlorate.
