The Environmental Guidance Division manages <br /> several other UST projects and those reports are submitted separately. <br /> UST 850-DlU1 <br /> We continued the investigation at the tank excavation that once contained <br /> UST 850-DlUl (850-41D). Soil and bedrock beneath the tank excavation <br /> contains diesel-fuel that was released during the 1985 tank removal <br /> operation. Characterization of soil and bedrock is now complete; ground <br /> water has not been contaminated with diesel-fuel. A report titled <br /> Investigation Report for the 850-DI UI Underground Storage Tank at <br /> Lawrence Livermore National Laboratory Site 300 will be sent to you by <br /> December 31, 1990. <br /> UST 874-DlU1 <br /> We completed the closure activities for UST 874-DlUl (874-11D) according to <br /> the "Application for Permit to Close Underground Storage Tank Storing <br /> Hazardous Materials" #39-1945-15. A report titled Closure Report for the <br /> 874-DI Ul Underground Diesel-Fuel System at Lawrence Livermore <br /> National Laboratory Site 300 was sent to you on October 26, 1990. <br /> An Equal Opportunity Employer-Universit yof Califomia-PO.Box 808 Livermore,California 94550*Telephone(415)422-1100-Twx 910-386-8339 UCLLL LVMR <br />
