New Items There were no new items discussed.

Response Item Item 66 SWPS Instrumentation.

E. Cviki provided a plot of the most recent delta settlement information for the west side of the SWPS. The delta settlement now is approximately 25 mils (the alert level is 50 mils). A visual check of the tendons, an optical survey and a review of dewatering data revealed no indication of t problem. In addition, the delta settlement is currently decreasing with time. Based upon this information, a lift off test on the tendons is not considered necessary. The erratic movement noted on 12/11 was probably an instrument malfunction. Engineering will continue to closely monitor the movement. This response satisfactorily addresses the Team's request for additonal information concerning this matter. (CLOSES ITEM 65-7)
