| Abstract |
The McKin site is located approximately 1.5 miles east of Gray Center on the Mayall Road in Gray, Maine. The site includes approximately 6 acres and is surrounded by residences, the closest being within 200 feet. The site lies in an abandoned sand and gravel pit and currently consists of a fenced enclosure, 21 tanks (12 of which are outside the fence), an incinerator, a concrete block building, an asphalt lined lagoon and other debris. In 1979, liquid wastes were removed from the site, however, non-pumpable sludges were left on-site. Most of the tank contents (33,500 gallons) and 165 fifty-five gallon drums of oil and chemical wastes were removed under the supervision of the Main Department of Environmental Protection. Air monitoring in 1982 showed high levels of volatile organics around the tanks. Remaining materials in the tanks were found to contain concentrations (up to 20%) of dichloroethylene, freon, trichloroethylene and xylene. Selected actions for this Initial Remedial Measure (IRM) include: on-site cleaning of the tanks, transport of empty tanks off-site for salvage, and transport of liquids and sludges off-site for disposal. Estimated capital cost for this IRM is $47,000. |
