2019-15632. National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List: Partial Deletion of the New Brighton/Arden Hills/Twin Cities Army Ammunition Plant (TCAAP) Superfund Site

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule; notification of intent.

SUMMARY:

The Environmental Protection Agency (EPA) Region 5 is issuing a Notice of Intent to Delete all soil and five aquatic sites in Operable Unit 2 (OU2) of the New Brighton/Arden Hills/TCAAP Superfund Site in Minnesota 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 Minnesota, through the Minnesota Pollution Control Agency (MPCA), have determined that all appropriate response actions identified for soil and these five aquatic sites in OU2 under CERCLA, other than operation and maintenance, monitoring and five-year reviews, have been completed. However, this deletion does not preclude future actions under Superfund.

DATES:

Comments must be received by August 22, 2019.

ADDRESSES:

Submit your comments, identified by Docket ID no. EPA-HQ-SFUND-1983-0002, by mail to Randolph Cano, NPL Deletion Coordinator, U.S. Environmental Protection Agency Region 5 (ST-6J), 77 West Jackson Boulevard, Chicago, IL 60604.

SUPPLEMENTARY INFORMATION:

In the “Rules and Regulations” section of today's Federal Register, we are publishing a direct final Notice of Partial Deletion of the New Brighton/Arden Hills/TCAAP Superfund Site without prior Notice of Intent for Partial Deletion because EPA views this as a noncontroversial revision and anticipates no adverse comment. We have explained our reasons for this deletion in the preamble to the direct final Notice of Partial Deletion, and those reasons are incorporated herein. If we receive no adverse comment(s) on this partial deletion action, we will not take further action on this Notice of Intent for Partial Deletion. If we receive adverse comment(s), we will withdraw the direct final Notice of Partial Deletion, and it will not take effect. We will, as appropriate, address all public comments in a subsequent final Notice of Partial Deletion based on this Notice of Intent for Partial Deletion. We will not institute a second comment period on this Notice of Intent for Partial Deletion. Any parties interested in commenting must do so at this time.

For additional information, see the direct final Notice of Partial Deletion which is located in the “Rules and Regulations” section of this Federal Register.
