Location and Description: The site is four miles
southwest of the city of Kimball, NE. The
site was one of nine Atlas missile sites operated by the U.S. Air
Force under the 549th Strategic Missile Squadron at Warren
Air Force Base, Wyoming. Improvements consisted of one
underground launch operations building and one launch and
service building, segregated storage buildings, sentry house,
helicopter pad, spray pond, roads, walks, fences, water, sewer,
and electrical systems. The facility was connected to the Kimball
city water system with a pump station located adjacent to the city water tower. The General
Services Administration excessed the site in August 1965.
Problem and Response: Due to trichloroethene groundwater contamination, a
Hazardous, Toxic and Radioactive Waste project has been initiated under the Formerly Uused Defense Sites Program
for this site.
Activities for 2015: The U.S. Army Corps of Engineers contractor completed the
proposed plan and decision document last year. The design and implementation of the full
scale remedy are to occur this year followed by performance monitoring to confirm that the
remedy continues to meet expectations for TCE mass reduction.
Proposed Activities for 2016: Under the
remedial action contract, the USACE contractor
will continue performance monitoring to track
reduction of the TCE contamination to attain final
remedy in place.
Issues and Other Information: The biggest challenge will be to satisfy NDEQ and
EPA concerns regarding reduction of the TCE-contaminated groundwater plume. Funding is
being programmed for 2016 to make the award of an option to continue operation and
monitoring of the remedial action in order to obtain site closure in 2021.
