EPA SELECTS CLEANUP ACTION FOR SUPERFUND SITE IN HEMPSTEAD, LONG ISLAND

EPA SELECTS CLEANUP ACTION FOR SUPERFUND SITE IN HEMPSTEAD, LONG ISLAND
 NEW YORK, May 4 /PRNewswire/ -- The U.S. Environmental Protection Agency (EPA) today announced it has selected a cleanup action that will treat chemically contaminated soils and ground water at the Pasley Solvents and Chemicals Superfund site, a former tank farm used for the storage of oils, solvents and chemicals located at 556 Commercial Ave. in the Town of Hempstead on Long Island.
 EPA estimates the cost of construction and operation of the ground water treatment system will be $12.1 million. It will be operational about two years after the design of the system is finalized. The soil treatment system will take two years to construct after design is completed and will cost an estimated $1.6 million. Superfund is the federal program to address hazardous waste sites.
 EPA Regional Administrator Constantine Sidamon-Eristoff said, "We have completed the lengthy but necessary process that brings us to this significant milestone, the selection of the final remedy for the site. We will use our Superfund enforcement authority to make those responsible for causing the problem pay to correct it."
 The New York State Department of Environmental Conservation (NYSDEC) has reviewed the selected remedy and agreed with EPA's decision. The major components of the selected remedy include:
 -- Treatment of approximately 13,000 cubic yards of contaminated soil;
 -- Disposal of treatment residuals at a disposal facility in compliance with federal and state regulations;
 -- Remediation of the ground water by extraction, treatment and recharge of treated ground water that will meet federal and state drinking water standards except in those cases where upgradient concentrations of contamination are above such standards;
 -- Implementation of a long-term monitoring program to track the migration and concentrations of the contaminants of concern; and
 -- Implementation of a system monitoring program that includes the collection and analysis of the influent and effluent from the treatment systems and periodic collection of well-head samples.
 Contamination upgradient of the site is suspected to be contributing to the ground water contamination at the site. The Roosevelt Field Site, which is an upgradient source, is listed as a Class II site on the New York State Registry of hazardous waste sites.
 The Purex/Mitchell Field Transit Facility site ("Purex") is the second major ground water contamination site in the area and is approximately 800 feet east of the site. An investigation in 1984 showed that contaminants in the upper Magothy aquifer associated with the Purex Site include: PCE; TCE; 1,1-dichloroethene; and methylene chloride. The ground water contamination from this site is currently being remediated by the Purex company pursuant to a New York State Consent Order.
 EPA and NYSDEC will ensure that any sources contributing to contamination at the site are addressed. In addition, during the remedial design process, EPA and NYSDEC will also ensure that the effectiveness of the Pasley remediation is not influenced by the ground water recovery system at the adjacent Purex Site.
 A public comment period on Pasley site-related documents and the proposed remedy was held from Feb. 14, 1992, through March 14, 1992. In addition, a public meeting was held on March 5, 1992, as part of EPA's community particpation program related to site activities.
 Site Description
 The 1/2-acre Pasley Solvents and Chemical site was a chemical distribution facility from 1969 to 1982. Prior to this, Commander Oil used the site for gasoline storage and fuel oil distribution. The Nassau County Health Department (NCDH) investigated the site in 1980 and found the on-site soil and ground water to be contaminated with organic solvents and petroleum products.
 Pasley conducted some limited investigation in 1981 at the request of the NYSDEC and the NCDH. In 1982, the company went bankrupt and indicated that it could not take responsibility for any cleanup actions. The site was placed on the National Priorities List (NPL) of hazardous waste sites in June 1986. NYSDEC was the lead agency for the cleanup of the site until January 1987, when EPA, with NYSDEC's concurrence, assumed responsibility for the cleanup.
 On Aug. 19, 1988, EPA issued an Superfund Administrative Order (AO) to Commander. The AO required Commander to perform a remedial investigation (RI) to determine the nature and extent of contamination at the site and a feasibility study (FS) to identify cleanup options. The Order also required Commander to remove the 12 above-ground tanks that were located on-site. Pasley declined to participate in the settlement.
 The tank farm removal was completed in November of 1988. The RI Report was approved by EPA in November 1991. The revised FS Report was submitted to EPA February 1992.
