Record of Decision Amendment for Operable Unit 1 [PDF 12.1 MB, 289 pp]

The two-acre Mattiace Petrochemical Co., Inc. Superfund site is an inactive chemical distribution and drum washing facility located on Long Island.  From the mind-1960’s until 1987 Mattiace Petrochemcial Co., Inc. received chemicals by tank truck and redistributed them to its customers.  The company also operated the M&M Drum Cleaning Company on the site until 1982. During its operational period, the former Mattiace property contained a Quonset hut shed, concrete loading dock, an approximately 56 storage tanks, most of which were underground. In 1986, the Mattiace Petrochemical Co. filed for bankruptcy as a result of legal problems resulting from its non-compliance with various environmental regulations. At the request of the State of New York, the bankruptcy court removed the protection of assets normally extended to a reorganizing company in 1987 in order to ensure that the company ceased operations. In February 1988, the EPA implemented a short term cleanup action which included waste characterization and the eventual removal of approximately 100,000 gallons of hazardous materials in drums, Underground Storage Tanks, and Above Ground Storage Tanks. The EPA added the site to the Superfund National Priorities List on March 30, 1989. Surrounding the site are industrial areas, including the Li Tungsten and Captains’s Cove Superfund properties, Garvies Point Preserve (designated by New York State as a significant natural habitat), tidal wetlands, and Glen Cove Creek.  Hempstead Harbor and Long Island Sound are located within three miles of the site and are used for recreation.

The groundwater, soil and soil gas at the site are primarily contaminated with volatile organic chemicals, contaminants that evaporate into the air easily.  The contamination at the site has been addressed through emergency cleanup actions and an on-going long term cleanup.

After many years of operation, the EPA has determined that the ground water pump and treat and soil vapor extraction systems were no longer effective at reducing the contaminated ground water and soil gas because it is not likely that the treatment system would reduce the contamination to acceptable levels in a reasonable time frame. The EPA has memorialized a change in the remedy in a ROD Amendment in September 2014 to address the remaining contamination found at the Site. The remedial components of the ROD Amendment include thermal treatment, bioventing, enhanced bioremediation, and a partial vertical barrier. Design of the new remedy is expected to begin taking place in 2015.
