Introduction
EPA Region II announces its intent to delete the Vestal Water Supply Well 4-2 Site (Site), located in Vestal, Broome County, New York, from the National Priorities List (NPL) and requests public comment on this action. The NPL constitutes appendix B to the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), which EPA promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). EPA identifies sites that appear to present a significant risk to public health, welfare, or the environment and maintains the NPL as the list of those sites. Sites on the NPL may be the subject of remedial actions financed by the Hazardous Substances Superfund Response Trust Fund (Fund). Pursuant to Sec. 300.425(e)(3) of the NCP, any site deleted from the NPL remains eligible for Fund-financed remedial actions, if conditions at such sites warrant such action.
The Vestal 4-2 Site is located on the west side of Prentice Road in the Town of Vestal, Broome County, New York. The Town of Vestal is about five miles southwest of Binghamton. Well 4-2 is about 1,000 feet south of the Susquehanna River and is one of four water supply wells in Water District Number 4 of the Town of Vestal.
EPA will accept comments concerning the Vestal 4-2 Site for thirty days after publication of this document in the Federal Register.

NPL Deletion Criteria
Section 300.425(e)(1) (i)-(iii) of the NCP provides that sites may be deleted from the NPL where no further response is appropriate. In making this determination, EPA, in consultation with the State of New York, considers whether any of the following criteria has been met:
(i) Responsible or other parties have implemented all appropriate response actions required; or,
(ii) All appropriate Fund-financed responses under CERCLA have been implemented and no further cleanup by responsible parties is appropriate; or,
(iii) The remedial investigation has shown that the release poses no significant threat to human health or the environment and, therefore, taking remedial measures is not appropriate.
-
Deletion Procedures
The following procedures were used for the intended deletion of the Site:
(1) Two Reports, issued in 1980 and 1981, determined that the source of Vestal 4-2 contamination was the Monarch Chemical, Inc. facility.
(2) In 1993, the Town of Vestal had a former dry well and surrounding soils removed from the Monarch facility.
(3) In 1997, groundwater sampling confirmed the cleanup of the aquifer.
(4) The New York State Department of Environmental Conservation (NYSDEC) concurred with the deletion in a letter dated September 29, 1998.
(5) EPA Region II has recommended deletion and has prepared the relevant documents. EPA has also made all relevant documents available in the Regional office and local Vestal 4-2 Site information repositories.
(6) Concurrent with this national Notice of Intent to Delete, a notice has been published in a local newspaper and has been distributed to appropriate Federal, State and local officials and other interested parties announcing a thirty-day public comment period on the deletion.
Comments received during the comment period will be evaluated before any final decision is made. If necessary, EPA Region II will prepare a Responsiveness Summary which will address any significant comments received during the public comment period. A deletion occurs when the EPA Regional Administrator places a final Notice of Deletion in the Federal Register.

Basis for Intended Site Deletion
In February 1980, Vestal Water Supply Well 4-2 was found to be contaminated with trichloroethene, 1,1,1-trichloroethane and tetrachloroethene. The Vestal 4-2 Site was listed on the NPL on September 1, 1983.
An October 1980 report entitled, ``Hydrogeologic Investigation of Organic Contamination at Monarch Chemicals, Inc.,'' and an April 7, 1981 draft report entitled, ``Hydrologic Study of a Portion of the Susquehanna River Valley in the Town of Vestal, Broome County, New York with Emphasis on Chemical Contamination of the Aquifer,'' together delineated the nature and extent of the suspected contamination at the Vestal 4-2 Site and documented that the Monarch facility was the source of contamination of Well 4-2.
The Monarch Chemicals is located approximately 200 feet south and hydraulically upgradient of Well 4-2. Monarch Chemicals began operations around 1970, repackaging chemicals including 1,1,1- trichloroethane, trichloroethene and other chlorinated solvents as part of a bulk chemical handling operation.
In April 1983, the ``Town of Vestal Water District No. 4, Groundwater Exploration'' report was released. The report found that the contamination in the vicinity of Well 4-2 was a localized condition. The report also indicated that although Monarch Chemicals vacated its premises in the Fall of 1982, the continued presence of contaminants in Well 4-2 indicated that the Monarch facility remained contaminated. The report recommended that Well 4-2 should continue to pump to waste unless another remedial action were taken to remove the contamination. These conclusions mapped out the remedial alternatives which were later incorporated in the New York State Enforcement Action, also known as the Settlement Agreements.
In 1985, the New York State Department of Law, Attorney General's Office along with the Town of Vestal and the Vestal Water Districts No. 3, 4 and 6 signed two Settlement Agreements with the responsible parties at the Site.
In September 1988, as a result of the Settlement Agreements, an air stripper and additional carbon filtration were installed at Well 4-2. The air stripping system reduced contaminant levels in groundwater to below detection limits.
On December 14, 1993, approximately 26 cubic yards (42 tons) of material were excavated including the former dry well and surrounding soils from the Monarch Chemicals facility.
In order to determine if groundwater contaminants had attenuated and if it were appropriate to begin the NPL delisting process for the Site, EPA sampled the groundwater in the vicinity of the Vestal 4-2 Site on May 8, 1997, June 11, 1997 and September 10, 1997. The results of the sampling showed that groundwater contamination in the vicinity of the former Monarch
[[Page 43643]]
Chemicals dry well had decreased, such that it was at or approaching drinking water standards.
EPA's 1997 sampling data are consistent with the Town's monthly monitoring results for samples collected prior to the air stripper. Therefore, the primary pathways associated with the Vestal 4-2 Site that threatened public health have been addressed. EPA summarized the actions taken at this Site in a Superfund Site Close Out Report dated September 30, 1998.
EPA and NYSDEC have determined that all appropriate responses under CERCLA at the Site have been completed, and that no further activities are necessary. Consequently, EPA is proposing deletion of this Site from the National Priorities List. Documents supporting this action are available in the docket.
Dated: July 27, 1999. Herb Barrack, Acting Regional Administrator, Region 2.
