I. Introduction

EPA Region 2 is publishing this direct final deletion of the Pfohl Brothers Landfill Superfund Site (Site) from the National Priorities List (NPL). The NPL constitutes Appendix B of 40 CFR Part 300, which is the National Oil and Hazardous Substances Pollution Contingency Plan, 40 CFR Part 300 (NCP), which EPA promulgated pursuant to section 105 of the Comprehensive Environmental and Liability Act (CERCLA) of 1980, as amended. 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 Substance Superfund (Fund). As described in Sec. 300.425(e)(3) of the NCP, a site deleted from the NPL remains eligible for remedial actions if conditions at the site warrant such action.

Because EPA considers this action to be noncontroversial and routine, this action will be effective September 22, 2008 unless EPA receives significant adverse comments by August 21, 2008. Along with this direct final Notice of Deletion, EPA is copublishing a Notice of Intent to Delete in the ``Proposed Rules'' section of today's Federal Register. If adverse comments are received within the 30day public comment period, EPA will publish a timely withdrawal of this Direct Final Deletion before the effective date of the deletion and the deletion will not take effect. EPA will, if appropriate, prepare a response to comments and continue with the deletion process on the basis of
[[Page 42534]]
the Notice of Intent to Delete and the comments received. In such a case, there will be no additional opportunity to comment.

Section II below explains the criteria for deleting sites from the NPL. Section III discusses procedures that EPA is using for this action. Section IV discusses the Site and demonstrates how it meets the deletion criteria. Section V discusses EPA's action to delete the Site from the NPL unless significant adverse comments are received during the public comment period.

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 accordance with Sec. 300.425(e)(1), EPA shall consult with the State to determine whether any of the following criteria have been met:

i. Responsible parties or other parties have implemented all appropriate response actions required;

ii. All appropriate Fundfinanced responses under CERCLA have been implemented, and no further action by responsible parties is appropriate; or

iii. The remedial investigation has shown that the release of hazardous substances poses no significant threat to public health or the environment and, therefore, taking of remedial measures is not appropriate.

In addition, the State shall concur with the deletion, as required by Sec. 300.425(e)(2), and the public shall be informed, as required by Sec. 300.425(e)(4). A site which is deleted from the NPL remains eligible for remedial actions should future conditions warrant such action, as set forth in Sec. 300.425(e)(3). Even if a site is deleted from the NPL, where hazardous substances, pollutants, or contaminants remain above levels that allow for unlimited use and unrestricted exposure, CERCLA section 121(c), 42 U.S.C. 9621(c) requires that a review of the site be conducted at least every five years after the initiation of the remedial action to ensure that the action remains protective of public health and the environment. If new information becomes available which indicates a need for further action, EPA may initiate remedial actions. If there is a significant release from a site deleted from the NPL, the deleted site may be restored to the NPL without application of the Hazard Ranking System, a numericallybased screening system that uses information from initial, limited investigations to assess the relative potential of sites to pose a threat to human health or the environment.

III. Deletion Procedures

The following procedures apply to deletion of the Site. (1) EPA consulted with the State of New York prior to developing this direct final Notice of Deletion and the Notice of Intent to Delete copublished today in the ``Proposed Rules'' section of the Federal Register.
(2) EPA has provided the State 30 working days for review of this notice and the parallel Notice of Intent to Delete prior to their publication today, and the State, through the NYSDEC, has concurred on the deletion of the Site from the NPL.
(3) Concurrently with the publication of this direct final Notice of Deletion, a notice of the availability of the parallel Notice of Intent to Delete is being published in a major local newspaper, The Buffalo News. The newspaper notice announces the 30day public comment period concerning the Notice of Intent to Delete the Site from the NPL. (4) EPA placed copies of documents supporting the proposed deletion in the deletion docket and made these items available for public inspection and copying at the Site information repositories identified above.
(5) If adverse comments are received within the 30day public comment period on this deletion action, EPA will publish a timely notice of withdrawal of this direct final Notice of Deletion before its effective date and will prepare a response to comments. If appropriate, EPA may then continue with the deletion process based on the Notice of Intent to Delete and the comments already received.

Deletion of a site from the NPL does not itself create, alter, or revoke any individual's rights or obligations. Deletion of a site from the NPL does not in any way alter EPA's right to take enforcement actions, as appropriate. The NPL is designed primarily for informational purposes and to assist EPA management. Section 300.425(e)(3) of the NCP states that the deletion of a site from the NPL does not preclude eligibility for future response actions, should future conditions warrant such actions.

IV. Basis for Site Deletion

The following summary provides the Agency's rationale for the proposal to delete this Site from the NPL.

Background

The Site consists of a 130acre inactive landfill and an adjacent 22acre borrow pit located in a commercial/residential area in the Town of Cheektowaga, Erie County, New York, approximately one mile northeast of Buffalo International Airport.

The Site is bordered by wetlands, Aero Lake, Aero Creek, and the New York State Thruway to the north. The remaining boundaries consist of Transit Road to the east, a Niagara Mohawk Power easement to the west, and residential properties (along the north side of Pfohl Road) and Conrail tracks to the south. A former New York Thruway Authority borrow area (Area A) is located just south of the New York State Thruway. The Site is bisected from west to east by Aero Drive. One disposal area is located immediately north of Aero Drive (Area B) and another disposal area is located immediately south of Aero Drive (Area C).

The Pfohl Brothers Landfill accepted municipal and industrial wastes from 1932 to 1971 from the surrounding townships, manufacturers, and utilities. The landfill was operated as a cut and fill operation, whereby waste and drums, which were filled with substances that could be spilled out, were emptied into 150foot diameter trenches. Some of the generators of the waste have indicated that pine tar pitch, waste paints and thinners, waste cutting oils, oilcontaminated Fuller's earth, phenolic tar containing chlorinated benzenes and dioxins, and oil and capacitors laden with polychlorinated biphenyls (PCBs) were disposed of at the Site. No records were kept as to the quantity of wastes received, other than an estimated 125 tons of phenolic tar. Limited historical records indicate that no hazardous wastes were disposed of in Area A. Soil from this area was used primarily by the New York Thruway Authority for road fill material.

A preliminary assessment of the Site was performed by EPA in 1982 to determine its hazard ranking. Based upon the analytical results, which indicated that the landfill leachate contained various volatile organic compounds, semivolatile organic compounds and metals, the Site was listed on the New York State Registry of Inactive Hazardous Waste Disposal Sites as a ``Class 2 Inactive Hazardous Waste Site'' in 1985.

Between 1983 and 1985, all of the residences near the Site were connected to the municipal drinking water supply system. Previously, these residents obtained drinking water from private wells.

The Site was added to the NPL on December 16, 1994 (FRL51247). [[Page 42535]]

Remedial Investigation and Feasibility Study (RI/FS)

An RI/FS was initiated in 1988 by NYSDEC. Various levels of volatile organic compounds, semivolatile organic compounds, PCBs, and metals were detected in the soil, groundwater, and sediment. In 1990, NYSDEC installed a fence around most of the Site.

A second RI/FS addressed Area A and the offsite groundwater contamination. Based upon the results of this investigation, it was determined that Area A was not used for the disposal of hazardous substances and significant levels of groundwater contamination were not detected.

Selected Remedy

A ROD for Areas B and C was issued by NYSDEC in February 1992. The selected remedy included capping the two disposal areas, construction of a leachate collection and conveyance system, construction of a barrier wall containment system around the outside perimeter of the disposal areas, collection and disposal of the drums and phenolic tars found onSite, and longterm monitoring of the groundwater at and near the landfill. The ROD also called for the implementation of institutional controls to protect the integrity of the containment remedy and to prevent the use of contaminated groundwater.

A ROD for Area A, issued on January 10, 1994, selected a ``no action'' remedy.

Response Actions

Under Orders on Consent with NYSDEC dated October 4, 1993 and April 11, 2001, the PRP Group performed the actions called for in the 1992 ROD.

The PRP Group commenced the design related to the containment system and leachate collection system in 1994; the design was approved by NYSDEC upon execution of the abovenoted Order on Consent in April 2001. Detailed information on the remedial construction is available in the September 2003 Remedial Action Report.

To facilitate future development along Pfohl Road and Aero Drive, approximately 31 acres of landfilled material, consisting of approximately 365,000 cubic yards of waste located along these roads (edges of Areas B and C) were excavated and consolidated on the interior portions of Areas B and C. In addition, 9,200 cubic yards of contaminated soil and waste were excavated to protect the adjacent wetlands and consolidated on the interior portions of Areas B and C. Postexcavation soil samples showed that the remaining soils met New York State's soil cleanup objectives, thereby eliminating all significant threats to human health and/or the environment. The excavated areas were backfilled and seeded.

Caps were constructed over the consolidated wastes in the two fill areas (approximately 70 acres in Area B and 24 acres in Area C) in conformance with 6 New York State NYCRR Part 360 closure requirements. The caps consist of a sixinch gas venting layer overlain by a layer of filter fabric, a 40mil thick very flexible polyethylene (VFPE) liner, a 24inch barrier protection layer of clean soil, and topped with six inches of topsoil capable of supporting vegetation. Fortynine gas vents were installed to convey the gas from beneath the low permeability layer of the caps via the gas venting layer to the atmosphere.

The leachate collection system consists of an 8inch diameter perforated solid collection pipe set in a wall of granular material which runs along the 10,000foot perimeter of the disposal areas. An additional 1,000 feet of collection drain was installed in the southwest interior of Area B to promote an upward gradient from the bedrock to the overburden aquifer within the confines of the perimeter barrier containment system. All of the collected leachate is discharged directly to the Cheektowaga PubliclyOwned Treatment Works via six collection wet wells and a force main that was constructed to the sewer interceptor on Rein Road. A VFPE wall keyed into 24 inches of undisturbed clay at the bottom of the perimeter trench was installed as a vertical barrier to prevent the collection drain system from collecting clean offSite groundwater and dewatering the adjacent wetlands. The VFPE wall was connected to the VFPE liner in the landfill cap. A Remedial Action Report documenting the completion of the Remedial Action was approved by EPA in September 2003.

The 1992 ROD called for the implementation of institutional controls to protect the integrity of the containment remedy and to prevent the use of contaminated groundwater. The restrictions were placed on Areas B and C in the form of Declarations of Covenants and Restrictions and Grant of Access signed by each of the seven owners whose parcels make up the Site. Five of the seven agreements were signed by the end of 2003 and the last two were signed in late 2005. Each Declaration requires that the owners agree not to use any onSite groundwater, not to construct onSite surface water cisterns, not to access the capped areas without prior written approval of NYSDEC, not to excavate, remove, or disturb the onSite soil without NYSDEC written approval, and not to plant trees and shrubs whose roots may breach the caps.

Cleanup Goals

The implemented actions protect human health and the environment. The landfilled areas have been capped, removing potential direct contact (i.e., ingestion or dermal contact of soil) exposures to the public. Institutional controls are in place to prevent potential exposures to the public, including trespassers. The potential impacts to groundwater are being addressed through the caps that reduce or prevent percolation through the landfilled areas and a barrier wall containment system around the outside perimeter of the disposal areas. The leachate collection system is discharging to an appropriate discharge facility to reduce potential exposures to the population. Groundwater monitoring data indicate that Siterelated contamination is not present outside the containment system. A final CloseOut report documenting the completion of the implementation of the site remedies was issued by EPA on December 10, 2007.

Operation and Maintenance

An operation and maintenance (O&M) plan, which provides for a long term monitoring program for the cover system, the drainage system, the groundwater, and the institutional controls, was approved in February 2006. The O&M activities at the Site are being performed by the Town of Cheektowaga. Semiannual O&M reports are reviewed by NYSDEC and EPA. FiveYear Review

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 reviews site remedies where such hazardous substances, pollutants, or contaminants remain no less often than every five years after the initiation of a remedy at a site. EPA conducted a fiveyear review of the Site in March 2006. The fiveyear review led EPA to conclude that human health and the environment are being protected by the remedial action implemented at the Site. The next fiveyear review is scheduled to be completed before March 2011. [[Page 42536]]

Community Involvement

Public participation activities for this Site have been satisfied as required in CERCLA sections 113(k) and 117, 42 U.S.C. 9613(k) and 9617. As part of the remedy selection process, the public was invited to comment on NYSDEC's proposed remedies. 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 repositories identified above.
Determination That the Site Meets the Criteria for Deletion From the NCP

All of the completion requirements for this Site have been met, as described in the December 2007 Final CloseOut Report. The State of New York, in a September 28, 2007 letter, concurred with the proposed deletion of this Site from the NPL.

The NCP specifies that EPA may delete a site from the NPL if ``all appropriate Fundfinanced response under CERCLA has been implemented, and no further response action by responsible parties is appropriate.'' 40 CFR 300.425(e)(1)(ii). EPA, with the concurrence of the State of New York, through NYSDEC, believes that this criterion for deletion has been met. Consequently, EPA is deleting this Site from the NPL. Documents supporting this action are available in the Site files. V. Deletion Action

EPA, with the concurrence of the State of New York, has determined that all appropriate responses under CERCLA have been completed and that no further response actions under CERCLA, other than O&M and five year reviews, are necessary. Therefore, EPA is deleting the Site from the NPL. Because EPA considers this action to be noncontroversial and routine, EPA is taking it without prior publication. This action will be effective September 22, 2008 unless EPA receives adverse comments by August 21, 2008. If adverse comments are received within the 30day public comment period of this action, EPA will publish a timely withdrawal of this Direct Final Deletion before the effective date of the deletion and the deletion will not take effect. EPA will, if appropriate, prepare a response to comments and continue with the deletion process on the basis of the Notice of Intent to Delete and the comments received. In such a case, there will be no additional opportunity to comment.
