Hoe Creek
Gillette, Wyoming

Office: Morgantown Energy Technology Center
Size:
80 acres (0.1 square mile)
Mission:
This facility, which is not owned by DOE, was used to investigate process and
environmental parameters of underground coal gasification technology.
Overview of Environmental Conditions:
Elevated levels of benzene and phenols in an onsite coal seam aquifer situated
about 180 feet beneath the surface. The contaminants have migrated onto private
property adjacent to the site.
CERCLA/RCRA Remediation Funding in FY 95: $1,584,000
|
The Hoe Creek Site is not on the National Priorities List. As a result of the
low Hazard Ranking Score, the site was classified as Site Evaluation
Accomplished, and DOE was directed to work with the State of Wyoming to
determine any site cleanup requirements.
Specific Cost Estimates and Budgetary Proposals
Funds budgeted for environmental restoration at Hoe Creek total $3.7 million of
appropriated funding for FY 96 and $1.5 million for FY 97 according to the
request in the President's Budget.
Progress in Conducting Remedial Actions
During FY 95, the final two rounds of four quarterly groundwater samples were
analyzed and the results were used to complete a cleanup alternatives study for
the site. The study was performed through an IAG with the Omaha District of the
U.S. Army Corps of Engineers. Biosparging (a combination of air injection and
biodegradation) was recommended to the State of Wyoming, which agreed to a
one-acre, 6-month field demonstration of the recommended alternative. EG&G
TSWV, Inc., the company which is conducting the field demonstration, is
scheduled to submit a report by July 1996. It is anticipated that the selected
cleanup technology description and schedule will be incorporated into the
Wyoming Agreement as an Appendix in early FY 97.
