Lawrence Livermore National Laboratory presently has three USTs, <br /> 827-D1U1,865-D1U1 and 871-D1U1 in that category at Site 300. These tanks contain <br /> diesel fuel for emergency stand-by generators or boilers. <br /> Enclosed is a summary and the results of the integrity tests performed by state licensed <br /> tank tester,Mr. Richard J. Silva (License No. 91-1437),of Clayton Environmental <br /> Consultants, Inc., Pleasanton,California for the month of February. These tests were <br /> done using Horner EZY-CHEK test equipment. <br /> Although the results of the tank integrity tests show the three tanks to be product tight, <br /> when 827-D1U1 was removed on March 11, 1994 several holes were in evidence.
