I. Introduction

EPA, Region 2, announces its intent to delete the Niagara County Refuse Superfund Site (Site) from the National Priorities List (NPL) and requests public comment on this action. EPA maintains the NPL as the list of sites that appear to present a significant risk to public health, welfare, or the environment. Sites on the NPL may be the subject of remedial actions financed by the Hazardous Substances Superfund Response Trust Fund (Fund). As described in § 300.425(e)(3) of the NCP, any site deleted from the NPL remains eligible for Fund-financed remedial actions, if conditions at the site warrant such action.

EPA will accept comments concerning the deletion of the Site from the NPL for thirty (30) days after publication of this document in the Federal Register.

Section II of this document explains the criteria for deleting sites from the NPL. Section III discusses procedures that the EPA is using for this action. Section IV discusses how the Site meets the NPL deletion criteria.

II. NPL Deletion Criteria

Section 300.425 (e) 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, shall consider whether any of the following criteria has been met:

(i) Responsible parties or other persons have implemented all appropriate response actions required;

(ii) All appropriate Fund-financed responses under CERCLA have been implemented, and no further response action by responsible parties is appropriate; or,

(iii) A remedial investigation has shown that the release poses no significant threat to public health or to the environment and, therefore, taking remedial measures is not appropriate.

III. Deletion Procedures

The following procedures apply to the deletion of this Site:

1. EPA, Region 2, issued a Record of Decision (ROD) for the Site on September 24, 1993, which selected the remedy for the Site.

2. Responsible parties implemented the remedy selected in the ROD as described in a Final Close Out Report dated August 14, 2003.

3. EPA, Region 2, recommends deletion and has prepared the relevant documents.

4. The State of New York, through the NYSDEC, concurred with the proposed deletion of the Site in a letter dated September 29, 2003.

5. A notice has been published in a local newspaper, and in addition, a notice has been distributed to appropriate Federal, State and local officials, and other interested parties announcing a 30-day public comment period which starts on the date of publication of this notice in the Federal Register and a newspaper of record.

6. The EPA has made available the relevant documents to this decision at the addresses listed above.

7. Upon completion of the thirty (30) day public comment period, EPA will evaluate all comments received before issuing a final decision on deletion. The EPA, Region 2, will prepare a Responsiveness Summary, if appropriate, which will address significant comments received during the public comment period. The Responsiveness Summary will be made available to the public at the information repositories.

If, after consideration of the comments it receives, EPA decides to proceed with the deletion, EPA will place a Notice of Deletion in the Federal Register. Deletion does not occur until the final Notice of Deletion is published in the Federal Register. Generally, the NPL will reflect deletions in the next final update following the final notice publication.

IV. Basis for Intended Site Deletion

The following summary provides a brief description and history of the Niagara County Refuse Superfund Site and provides the Agency's rationale for recommending deletion of the Site from the NPL.

The Niagara County Refuse site is a former municipal landfill, comprised of approximately 65 acres, located along the eastern border of the Town of Wheatfield, New York and the western border of the City of North Tonawanda. The southern edge of the Site lies approximately 500 feet north of the Niagara River.

During the landfill's operational period (1968-1976), the Niagara County Refuse Disposal District (NCRDD) accepted municipal refuse and industrial wastes, which are commingled throughout the landfill. More than 100 waste generators or transporters are thought to have used the Site. Disposed materials included heat-treatment salts, plating-tank sludge, tetrachloroethylene, PVC skins and emulsion, thiazole polymer blends, polyvinyl alcohol, phenolic resins, and brine sludge containing mercury.

Beginning in 1980, the Site became the focus of several investigations by EPA, NYSDEC, and the United States Geological Survey (USGS) resulting in the Site being placed on the National Priorities List (NPL) in September 1983.

In March 1989, a group of fourteen potentially responsible parties (PRPs) entered into an administrative consent order with EPA to perform a Remedial Investigation/Feasibility Study (RI/FS). In February 1995, a group of twelve PRPs entered into a judicial consent decree with the United States on behalf of EPA to conduct the remedial design, remedial construction, operation, maintenance, and monitoring for the Site. EPA signed a Record of Decision (ROD) for the Site on September 24, 1993, selecting the remedy for the Site as follows:

—Construction of a New York State Part 360 Standard Landfill Cap;

—Construction of a clay perimeter barrier wall;

—Construction of a gas venting system beneath the cap;

—Construction of a leachate collection system;

—Removal of the field tile drains located to the west of the landfill;

—Performance of an ecological assessment of the adjacent wetlands;

—Implementation of deed and access restrictions;

—Implementation of a long-term operation & maintenance program for the cap, and gas venting and leachate collection systems; and

—Implementation of long-term air and water quality monitoring.

On-site construction at the Site commenced in November 1998, continuing unabated through the next two construction seasons and in September 2000, EPA conducted a final inspection with NYSDEC and the PRPs. In December 2000, EPA issued its approval of the Remedial Action Report. The ecological assessment recognized that there were valuable wetlands and uplands located on the Site. A restoration plan was developed and implemented to account for the wetland losses incurred by the capping, and 0.17 acres of wetland were created as part of the work done at the Site. The success of the restoration effort is described in the Site Annual Monitoring Reports. Additionally, institutional controls, consisting of recording the Consent Decree and placing restrictive covenants on the real property at the Site, have been implemented by Niagara County and the Town of Wheatfield.

An Operation, Maintenance, and Monitoring (OM&M) Manual was developed and implemented. Financial assurance for OM&M activities has been provided by the PRPs in the form of demand notes as required by the Consent Decree. Annual reports are provided to EPA and NYSDEC and both EPA and NYSDEC believe that the reports for 2001 and 2002 confirm that the remedy for the Site has been successfully implemented.

The Site has been cleaned and environmentally valuable lands restored. The Site no longer poses an unacceptable risk to human health or the environment. However, hazardous substances remain at the Site above levels that would allow for unlimited use with unrestricted exposure. Pursuant to section 121(c) of CERCLA, EPA and/or the State will review site remedies no less often than every five years. The EPA, Region 2, conducted a Five-Year Review of the Site in November 2003. The Five-Year Review concluded that the contamination at the Niagara County Refuse site is under control and there is no exposure to human or environmental receptors from Site-related contaminants due to permanent measures in place at the Site.

Public participation activities for this Site have been satisfied as required in CERCLA section 113(k), 42 U.S.C. 9613(k), and section 117, 42 U.S.C. 9617. The ROD was subject to a public review process. All other documents and information which EPA relied on or considered in recommending this deletion are available for the public to review at the information respositories.

One of the three criteria for site deletion is when “responsible parties or other persons have implemented all appropriate response actions required” (40 CFR 300.425(e)(1)(i)). EPA, with the concurrence of the State of New York, through the NYSDEC, believes that this criterion for deletion has been met. Subsequently, EPA is proposing deletion of this Site from the NPL.
