04-21806. National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List

AGENCY:

Environmental Protection Agency.

ACTION:

Final rule; Notice of deletion of the Love Canal Superfund site from the National Priorities List.

SUMMARY:

The United States Environmental Protection Agency (EPA) Region II Office announces the deletion of the Love Canal Superfund site (Love Canal site) from the National Priorities List (NPL). The Love Canal site is located in the City of Niagara Falls, Niagara County, New York. The NPL constitutes appendix B to the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), 40 CFR part 300, which EPA promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended.

EPA and the State of New York, through the Department of Environmental Conservation (NYSDEC), have determined that all appropriate response actions have been implemented at the Love Canal site and that no further response actions, other than operation, maintenance, and monitoring, are required. In addition, EPA and NYSDEC have determined that the remedial action taken at the Love Canal site is protective of public health and the environment and that the operation, monitoring, and maintenance of such remedial action will confirm that it continues to be protective of public health and the environment.

Even though the Love Canal site will be deleted from the NPL, these ongoing monitoring activities will ensure NYSDEC and EPA involvement during the annual monitoring of the Love Canal site conditions, as well as the annual review of existing institutional controls.

DATES:

Effective, September 30, 2004.

SUPPLEMENTARY INFORMATION:

To be deleted from the NPL is: the Love Canal Superfund site, City of Niagara Falls, Niagara County, New York. A Notice of Intent to Delete for the Love Canal site was published in the Federal Register on March 17, 2004. The closing date for comments on the Notice of Intent to Delete was April 16, 2004.

EPA received comments, including the two major comments discussed below, on the proposed deletion and addressed these comments in a Responsiveness Summary. Several commenters expressed concern that the wastes that were originally disposed of in the Love Canal landfill have not been removed. The containment, leachate collection, and treatment and monitoring remedy at the Site was selected consistent with the requirements of the Federal Superfund law. Excavation and removal of hazardous materials from landfills can potentially create more contaminant exposure to human health and the environment than a containment remedy. Moreover the large volumes of contaminated soils from an excavated landfill must be treated and redisposed of at other secure hazardous waste facilities, requiring either utilization of limited existing landfill capacity or the creation of new landfills to accommodate the excavated waste from old landfills. The excavated landfill requires filling with clean backfill materials and still must be subject to engineering controls due to residual contamination that could not practicably be removed. For these reasons, EPA developed a presumptive remedy for large landfills consisting of containment through capping and leachate collection and treatment. The Love Canal site remedy is a permanent remedy that is consistent with the requirements of the Superfund law. Several commenters were also concerned that the deletion of the Love Canal site from the NPL would imply that EPA will not have any further involvement at the Love Canal site and that, if there were to be a need for further Superfund response at the Love Canal site, such a response could not be provided since the Love Canal site would no longer be on the NPL. EPA confirmed in the Responsiveness Summary that its responsibility for the Love Canal site does not cease after the deletion from the NPL.

The NCP (40 CFR 300.425 (e)) states that a site that is deleted from the NPL is eligible for further fund-financed remedial actions should future conditions warrant such action. A Superfund site can be deleted from the NPL when one of the following criteria, as identified in the NCP (40 CFR 300.425(e)), is met. These criteria are as follows: (1) Responsible or other parties have implemented all appropriate response actions required; (2) all appropriate Fund-financed response under CERCLA has been implemented and no further response action by responsible parties is appropriate; or, (3) 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. In the case of the Love Canal site, the first two criteria have been met. The third criterion is not applicable, since remedial measures were taken.

All of the comments received and EPA's responses are contained in the Responsiveness Summary, a copy of which is available at the EPA Public Information Office, Niagara Falls, New York at [phone]. The Responsiveness Summary is also available in the Administrative Record File, located in the EPA Regional Office.

As part of EPA's policy for Superfund sites where the remedy will result in substances remaining on-site above health-based levels that would allow for unrestricted use or unlimited exposure, EPA conducts five-year reviews to confirm that the remedy continues to adequately protect human health and the environment. In the case of the Love Canal site, the institutional controls in place do not allow for unrestricted use or unlimited exposure. In September 2003, EPA issued the first five-year review report for the Love Canal site operations. NYSDEC provided technical oversight for the preparation of EPA's five-year review report and concurred with EPA's findings that the containment and barrier drain system were working properly. EPA concludes that the Site does not pose a significant threat to public health or the environment.

EPA identifies sites that appear to present a significant risk to public health or the environment, and it maintains the NPL as the list of those sites. As described in § 300.425(e)(3) of the NCP, any site or portion thereof deleted from the NPL remains eligible for remedial actions in the unlikely event that conditions at the site warrant such action in the future. Deletion of a site from the NPL does not affect potentially responsible party liability or impede agency efforts to recover costs associated with response efforts.
