Stage of Clean-up: Construction Completed
Conditions at listing (December l982): The McKin Co. Site occupies about l0 acres in Gray, Maine. It is a privately owned abandoned sand and gravel site consisting of a fenced enclosure, an incinerator, a concrete-block building, an asphalt-lined lagoon, several large storage tanks, numerous 55-gallon drums, and other debris. The operation was constructed for waste generated when the Tamano, a Norwegian tanker, ran aground on a ledge in Hussey Sound, spilling 100,000 gallons of industrial fuel. In addition to the Tamano wastes, the owners also accepted septic tank wastes and industrial process wastes. As early as l973, residents of East Gray reported odors in well water and discoloration of laundry. As the number of complaints increased, it became apparent that a contaminated plume was moving through the aquifer. In August l977, an Emergency Health Ordinance was issued to prohibit any new construction within about 2 miles of the site. In November l977, EPA conducted a hydrogeologic assessment of the area. About this time, the Farmers Home Administration provided an alternate water supply for contaminated private wells in the area. In December l977, Gray issued a cleanup order to McKin Co. The State then removed the remaining wastes from all tanks, identified organic chemicals in the contents, and drilled over 75 shallow soil borings, which identified two areas of gross soil contamination.
