It was reported on 12/18/92, under Occurrence Report number:
RL--WHC-WHC60OEM-1990-0337, that one service station tank
(100-SS-27) had leaked. To further characterize that leak,
tank IOON-SS-28 was removed on 7/17/91. At the time of
removal of tank 100N-SS-28, petroleum product was observed
in the excavation area. Tank 100N-SS-28 was tightness
tested 10/90 and passed. There has been no petroleum in
100N-SS-28 since it was emptied in December 1990. The
excavation was approximately 12 feet below grade. Area that
was found to contain product material was ten feet by ten
feet.
