Dear Board Members:
21, 1984, from R J Erhardt to H R Denton, By copy of a letter dated November 3
k in 1977 the Board was informed that logs "B-1 through B-4" of borings 2

of the information in borings B-1 through B-4, concluded that liquefaction did not pose a safety problem for the tanks. Subsequently, but prior to his
" testimony on November 20, 1982, Dr Woods reviewed th-data from the records B-1 through B-4 later found to be arroneous and determined that they did not
. alter his previous conclusion.-
In presentations to the NRC Staff that preceded the filing of testimony,
' Consumers Power technical staff concluded that the sand pocket found in boring DF-5 does not extend beyond the tank area, in part, on the basis of infor-mation contained in the log of 1977 boring B-1 that has now been determined to
'be invalid. Testing data available from the B-1 through B-4 borings taken in the diesel fuel tank area indicate material acceptable for its intended purpose at the elevations where tests were taken, however none of the borings extend to the depth necessary to provide information as to the actual extent of the sand pocket observed in boring DF-5.
Because of these circumstances, the Applicant has determined that the analysis of the liquefaction potential of the soils beneath the diesel fuel oil tanks is inconclusive.
Because of the shutdown of the Midland project, the Applicant does not now plan to perform the additional analyses or obtain additional field information to close out this issue. We will keep the Board. informed of any further developments on this matter.
Thank you for your attention.
