I. Introduction

EPA is issuing a proposed rule to partially delete three sites from the NPL and requests public comments on these proposed actions. The NPL constitutes appendix B of 40 CFR part 300 which is the NCP, which EPA created under section 105 of the CERCLA statute of 1980, as amended. EPA maintains the NPL as those 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). These partial deletions are proposed in accordance with 40 CFR 300.425(e) and are consistent with the Notice of Policy Change: Partial Deletion of Sites Listed on the National Priorities List. 60 FR 55466 (November 1, 1995). As described in 40 CFR 300.425(e)(3) of the NCP, a site or portion of a site deleted from the NPL remains eligible for Fund-financed remedial action if future conditions warrant such actions. EPA will accept comments on the proposal to delete or partially delete these sites 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. of this document discusses procedures that EPA is using for this action. Section IV. of this document discusses the site or portion of the site proposed for deletion and demonstrates how it meets the deletion criteria, including reference documents with the rationale and data principally relied upon by the EPA to determine that the Superfund response is complete.

II. NPL Deletion Criteria

The NCP establishes the criteria that EPA uses to delete sites from the NPL. In accordance with 40 CFR 300.425(e), sites may be deleted from the NPL where no further response is appropriate. In making such a determination pursuant to 40 CFR 300.425(e), EPA will consider, in consultation with the State, whether any of the following criteria have been met: i. Responsible parties or other persons have implemented all appropriate response actions required; ii. All appropriate Fund-financed response under CERCLA has been implemented, and no further response action by responsible parties is appropriate; or iii. The remedial investigation has shown that the release poses no significant threat to public health or the environment and, therefore, the taking of remedial measures is not appropriate. Pursuant to CERCLA section 121(c) and the NCP, EPA conducts five- year reviews to ensure the continued protectiveness of remedial actions where hazardous substances, pollutants, or contaminants remain at a site above levels that allow for unlimited use and unrestricted exposure. EPA conducts such five-year reviews even if a site is deleted from the NPL. EPA may initiate further action to ensure continued protectiveness at a deleted site if new information becomes available that indicates it is appropriate. Whenever 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.

III. Deletion Procedures

In accordance with 40 CFR 300.425(e), the following procedures apply to the deletion or partial deletion of the sites in this proposed rule: (1) EPA consulted with the respective State before developing this Notice of Intent for deletion. (2) EPA has provided the State 30 working days for review of site deletion documents prior to publication of it today. (3) In accordance with the criteria discussed above, EPA has determined that no further response is appropriate. (4) The State, through their designated State agency, has concurred with the proposed deletion action. (5) Concurrently, with the publication of this Notice of Intent for deletion in the Federal Register, a notice is being distributed to the surrounding community via one or more of the following methods: publication in a major local newspaper of general circulation near the site, a news release, listservs, social media, or the site's web page. The notice announces the 30-day public comment period concerning the proposed action for deletion. (6) 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 Regional Records Center identified above. If comments are received within the 30-day comment period on this document, EPA will consider the comments and respond accordingly before making a final decision to delete or partially delete the site. If necessary, EPA will prepare a Responsiveness Summary to address any significant public comments received. After the public comment period, if EPA determines it is still appropriate to delete or partially delete the site, the EPA will publish a final Notice of Deletion or Partial Deletion in the Federal Register. Public notices, public submissions and copies of the Responsiveness Summary, if prepared, will be made available to interested parties and included in the site information repositories listed above. Deletion of a site or a portion of a site from the NPL does not itself create, alter, or revoke any individual's rights or obligations. Deletion of a site or a portion 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 Full Site or Partial Site Deletion

The sites to be deleted or partially deleted from the NPL, the location of the site, and docket number with information including reference documents with the rationale and data [[Page 53836]] principally relied upon by the EPA to determine that the Superfund response is complete are specified in table 1. The NCP permits activities to occur at a deleted site, or that media or parcel of a partially deleted site, including operation and maintenance of the remedy, monitoring, and five-year reviews. These activities for the site, or portion of the site being deleted, are entered in table 1, if applicable, under Footnote such that; 1 = site, or portion of the site, has continued operation and maintenance of the remedy, 2 = site, or portion of the site, receives continued monitoring, and 3 = site, or portion of the site, five-year reviews are conducted. Table 1 ---------------------------------------------------------------------------------------------------------------- Site name City/county, state Type Docket No. Footnote ---------------------------------------------------------------------------------------------------------------- U.S. Smelter & Lead Refining Inc..

Table 2 includes information concerning whether the full site is proposed for deletion from the NPL or a description of the area, media or Operable Units (OUs) of the NPL site proposed for partial deletion from the NPL. Table 2 ------------------------------------------------------------------------ Full site deletion (full) or Site name media/parcels/description for partial deletion ------------------------------------------------------------------------ U.S. Smelter & Lead Refining Inc....... Surface and subsurface soils (soils) portion of a 52.54- acre commercial/industrial property located within Modified Zone 1 and within a small portion of Zone 1 and Zone 2 of Operable Unit 1 (OU1). Tippecanoe Sanitary Landfill, Inc...... The land/soil portion of the site including the landfill area, perimeter drainage area, and wetlands. Fort Riley............................. Operable Unit 2, also called the Pesticide Storage Facilities Area (PSF), covers about \2/3\ of an acre around former building 348. ------------------------------------------------------------------------ EPA maintains the NPL as the list of sites that appear to present a significant risk to public health, welfare, or the environment. Deletion from the NPL does not preclude further remedial action. Whenever 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. Deletion of a site from the NPL does not affect responsible party liability in the unlikely event that future conditions warrant further actions.
