HWAAP-K03G
UST AT CAMP JUMBO
SITE DESCRIPTION
Site HWAAP-K03 has been broken up into 7 sub-sites (a-g) for easier tracking. A former underground storage tanks (UST) site located approximately 1 mile  west of the HWAD main gate on U.S. Highway 95. Five USTs were in operation from about 1931 to 1991 and leaked petroleum for a number of years. Ground water at this site is estimated to be about 300 ft. bgs. All USTs were removed and are considered closed. Closure was accomplished in 1996.. The highest level of TPH-diesel found in the soil during the tank removal was over 6,000 mg/kg at a depth of 8-feet. Additional soil borings and sampling to 30 feet did not detect any TPH-diesel.
PROPOSED PLAN
A Closure Decision Document was approved by the NDEP in October 1996. The document was resubmitted in April 2011 to include figures.
