ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 300

[EPA-HQ-SFUND-1990-0011; FRL-9676-7]

National Oil and Hazardous Substances Pollution Contingency Plan; 
National Priorities List: Partial Deletion of the Ellsworth Air Force 
Base Superfund Site

AGENCY: Environmental Protection Agency.

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) Region 8 announces 
the deletion of Operable Unit (OU) 1--the former Fire Protection 
Training Area (FPTA), along with two other Areas of Concern (AOC): the 
Gateway Lake Ash Study Area and the Pride Hangar Study Area of the 
Ellsworth Air Force Base (AFB) from the National Priorities List (NPL). 
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). This partial deletion 
pertains to the surface soil, unsaturated subsurface soil, surface 
water and sediments of Operable Unit (OU) 1, the Gateway Lake Ash Study 
Area, and the Pride Hangar Study Area. The groundwater medium 
associated with OU-11, Basewide Groundwater will remain on the NPL. The 
EPA and the State of South Dakota, through the Department of 
Environment and Natural Resources, have determined that all appropriate 
response actions under CERCLA, other than five-year reviews have been 
completed. However, the deletion of these parcels does not preclude 
future actions under Superfund.

DATES: Effective Date: This action is effective May 25, 2012.

SUPPLEMENTARY INFORMATION: The portion of the site to be deleted from 
the NPL is: Operable Unit (OU) 1--the former Fire Protection Training 
Area (FPTA), along with two other Areas of Concern (AOC): the Gateway 
Lake Ash Study Area and the Pride Hangar Study Area of the Ellsworth 
Air Force Base, Rapid City, South Dakota. A Notice of Intent for 
Partial Deletion for this Site was published in the Federal Register on 
March 13, 2012.
    The closing date for comments on the Notice of Intent for Partial 
Deletion was April 12, 2012. No public comments were received and EPA 
still believes the partial deletion action is appropriate.
    EPA maintains the NPL as the list of sites that appear to present a 
significant risk to public health, welfare, or the environment. 
Deletion of a site 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 portions of a 
site from the NPL does not affect responsible party liability, in the 
unlikely event that future conditions warrant further actions.
