    Stage of Clean-up: Construction Underway

    Conditions at Proposal (July 29, 1991): New Hampshire Plating Co. (NHPC) formerly conducted electroplating operations on a 13.1-acre leased property on Wright Avenue in Merrimack, Hillsborough County, New Hampshire. The surrounding area is primarily used for light industrial and commercial purposes, with some residential areas nearby. During the lifetime of the plant (1962-85), NHPC discharged electroplating waste water and wastes into a system of four natural lagoons in a wetland on the property. The lagoons were unlined and had no leachate detection or collection system. In 1980, NHPC notified EPA that it was a hazardous waste disposal facility under Subtitle C of the Resource Conservation and Recovery Act (RCRA). An inspection by the New Hampshire Department of Environmental Services (NH DES) and EPA in April 1982 noted several RCRA violations. As a result, the New Hampshire Division of Public Health Services issued a Notice of Violations and Order of Abatement to NHPC. In February 1983, the State of New Hampshire filed a civil suit against NHPC, and was awarded a $600,000 attachment of property. NHPC halted operations in 1985 because it lacked the financial resources necessary to meet compliance standards and continue hydrogeologic investigations at the property.  More...
