ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 300
[EPA-HQ-SFUND-1990-0011; FRL-8249-8]
National Oil and Hazardous Substances Pollution Contingency Plan;
National Priorities List
AGENCY: Environmental Protection Agency.
ACTION: Notice of partial deletion of the Ellsworth Air Force Base
National Priorities List Site from the National Priorities List.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency, Region 8 (EPA) announces
the deletion of portions of the Ellsworth Air Force Base (AFB) Site
located in Meade and Pennington Counties, South Dakota, from the
National Priorities List (NPL). All areas originally proposed for
deletion under the Notice of Intent to Partially Delete published in
the Federal Register on June 28, 2006 (71 FR 36736) are being deleted.
The NPL constitutes Appendix B to the National Oil and Hazardous
Substances Pollution Contingency Plan, 40 CFR Part 300, which EPA
promulgated pursuant to Section 105 of the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA).
EPA has determined, with the concurrence of the State of South
Dakota through the Department of Environment and Natural Resources that
the parcels pose no significant threat to public health, welfare or the
environment and, therefore, no further response action pursuant to
CERCLA is appropriate. This partial deletion pertains to surface soil,
unsaturated subsurface soil, surface water, and sediments at Operable
Units 2, 3, 4, 5, 6, 7, 8, 9, 10 and 12, and excludes the ground water
medium at these parcels. The ground water medium at the Ellsworth AFB
Site (OU-11, Basewide Ground Water), and the soil medium (surface and
unsaturated subsurface soils) at OU-1, Fire Protection Training Area,
will remain on the NPL and response activities will continue for those
OUs. Two additional areas not associated with an operable unit, the
Gateway Lake Ash Study Area and the Pride Hangar Study Area, are
currently under investigation and are also not part of this partial
deletion.
DATES: Effective Date: This rule is effective on December 4, 2006.
FOR FURTHER INFORMATION CONTACT: Mr. Jeff Mashburn, P.E., Remedial
Project Manager (8EPR-F), U.S. EPA, Region 8, 999 18th Street, Suite
300, Denver, CO 80202-2466, Phone: (303) 312-6665.
SUPPLEMENTARY INFORMATION: Ellsworth AFB is a U.S. Air Force Air Combat
Command installation located 12 miles east of Rapid City, South Dakota,
and adjacent to the small community of Box Elder. The main Air Force
Base covers approximately 4,858 acres within Meade and Pennington
counties and includes runways, airfield operations, industrial areas,
housing, and recreational facilities.
On June 28, 2006 EPA published a Notice of Intent of Partial
Deletion in the Federal Register (71 FR 36736) and local newspapers
which proposed to delete the surface soil, unsaturated subsurface soil,
surface water and sediment media at OU-2, OU-3, OU-4, OU-5, OU-6, OU-7,
OU-8, OU-9, OU-10 and OU-12 (approximately 542 acres) and the surface
soil, unsaturated subsurface soil, surface water and sediment media of
an additional 4,300 acres which are not associated with an operable
unit and are not identified as posing a risk to human health or the
environment. EPA received one comment from the State of South Dakota in
support of the partial deletion. EPA agrees that the completion of the
remedy requirements and ongoing monitoring programs adequately
demonstrate that these parcels do not present a threat to the
environment or human health and the deletion from the NPL is
appropriate.
EPA identifies sites that appear to present a significant risk to
public health, welfare and the environment and maintains the NPL as the
list of those sites. Deletion from the NPL does not preclude further
remedial action. If a significant release occurs at a facility deleted
from the NPL, that facility is restored to the NPL without application
of the Hazard Ranking System. Deletion of the site from the NPL does
not affect responsible party liability for further remedial actions, in
the unlikely event that future conditions warrant such actions.
