2. The acceptance criteria / reporting requirements (i.e., Technical Specifications ACTION statements and Limiting Conditions for Operation) for allowable total and differential settlement as described in our December 1,1978 letter, would be incorporated into the plant procedure used in performing survr.I and evaluating settlement, with one exception:

The 0.1-inch deviation requiring re-surveying would be changed to a 0.25-inch deviation.

3. A building settlement survey and evaluation would be performed following any significant environmental event (earthquake, flood, tornado, hurricane) which might affect building settlement.

4. As stated in our September 27th letter, GPC would revise the procedure within 60 days following the NRC's approval of the building settlement Technical Specifications deletion.

In the October 21, 1986, meeting, the NRR Reviewer requested that GPC submit to the NRC additional clarifying information relative to several areas of discussion. The requested information is provided in the enclosure.
