National Oil and Hazardous Substances Pollution Contingency Plan; 
National Priorities List: Partial Deletion of the OU1 of the Libby 
Asbestos Superfund Site

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; notice of intent.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) Region 8 is issuing 
a Notice of Intent to Delete Operable Unit 1 (OU1), Former Export 
Plant, of the Libby Asbestos Superfund Site (Site), located in Lincoln 
County, Montana, from the National Priorities List (NPL) and requests 
public comments on this proposed action. The NPL, promulgated pursuant 
to section 105 of the Comprehensive Environmental Response, 
Compensation, and Liability Act (CERCLA) of 1980, as amended, is an 
appendix of the National Oil and Hazardous Substances Pollution 
Contingency Plan (NCP). The EPA and the State of Montana (State), 
through the Department of Environmental Quality (DEQ), have determined 
that all appropriate response actions at OU1 under CERCLA, other than 
operation and maintenance and five-year reviews (FYR), have been 
completed. However, this partial deletion does not preclude future 
actions under Superfund. This partial deletion pertains only to OU1. 
Operable Unit 2 (OU2), Former Screening Plant, was deleted from the NPL 
on April 10, 2019. Operable Unit 3 (OU3), Former Vermiculite Mine; 
Operable Unit 4 and Operable Unit 7 (OU4/OU7), Residential/Commercial 
Properties of Libby and Troy; Operable Unit 5 (OU5), Former Stimson 
Lumber Mill; Operable Unit 6 (OU6), BNSF Rail Corridor; and Operable 
Unit 8 (OU8), Highways and Roadways, are not being considered for 
deletion as part of this proposed action and will remain on the NPL.

DATES: Comments must be received by February 24, 2020.

I. Introduction

    EPA Region 8 announces its intent to delete all of Operable Unit 1 
(OU1), Former Export Plant, of the Libby Asbestos Superfund Site (Site) 
from the NPL and requests public comment on this proposed action. The 
NPL constitutes appendix B of 40 CFR part 300 which is the NCP, which 
the EPA promulgated pursuant to section 105 of the CERCLA of 1980, as 
amended. The EPA maintains the NPL as those sites

[[Page 4250]]

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). This 
partial deletion of OU1 of the Libby Asbestos Superfund Site is 
proposed in accordance with 40 CFR 300.425(e) and is consistent with 
the Notice of Policy Change: Partial Deletion of Sites Listed on the 
National Priorities List. 60 FR 55466 (Nov. 1, 1995). As described in 
Sec.  300.425(e)(3) of the NCP, a portion of a site deleted from the 
NPL remains eligible for Fund-financed remedial action if future 
conditions warrant such actions.
    The EPA will accept comments on the proposal to partially delete 
this site 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 where to access and review 
information that demonstrates how the deletion criteria have been met 
at OU1 of the Libby Asbestos Superfund Site.

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), the 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 in not appropriate.
    Pursuant to CERCLA section 121(c) and the NCP, the 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. The EPA conducts such five-year reviews even if a site is 
deleted from the NPL. The 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

    The following procedures apply to deletion of OU1 of the Libby 
Asbestos Superfund Site:
    (1) The EPA consulted with the State before developing this Notice 
of Intent for Partial Deletion.
    (2) The EPA has provided the State 30 working days for review of 
this document prior to its publication in the Federal Register.
    (3) In accordance with the criteria discussed above, EPA has 
determined that no further response is appropriate;
    (4) The State of Montana, through the DEQ, has concurred with 
deletion of OU1 of the Libby Asbestos Superfund Site, from the NPL.
    (5) Concurrently with the publication of this Notice of Intent for 
Partial Deletion in the Federal Register, notices are being published 
in the Western News, the Kootenai Valley Record, and The Montanian. The 
newspaper notices announce the 30-day public comment period concerning 
the Notice of Intent for Partial Deletion of the Site from the NPL.
    (6) The EPA placed copies of documents supporting the proposed 
partial deletion in the deletion docket, made these items available for 
public inspection, and copying at the Site information repositories 
identified above.
    If comments are received within the 30-day comment period on this 
document, the EPA will evaluate and respond to the comments before 
making a final decision to delete OU1. If necessary, the EPA will 
prepare a Responsiveness Summary to address any significant public 
comments received. After the public comment period, if the EPA 
determines it is still appropriate to delete OU1 of the Libby Asbestos 
Superfund Site, the Regional Administrator will publish a final Notice 
of 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 portion of a site from the NPL does not itself 
create, alter, or revoke any individual's rights or obligations. 
Deletion of a portion of a site from the NPL does not in any way alter 
the 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 Intended Partial Site Deletion

    The EPA placed copies of documents supporting the proposed partial 
deletion in the deletion docket. The material provides explanation of 
EPA's rationale for the partial deletion and demonstrates how it meets 
the deletion criteria. This information is made available for public 
inspection in the dockets identified above.
