Dear Mr. Noonan:

Additional information on subsidence monitoring was requested per the South Texas Project Safety Evaluation Report (NUREG-0781), Confirmatory Item

The instrumentation is observed at the frequencies as itemized in Table 2.5.C-1. The data which is tabulated and graphed in the FSAR Table 2.5.C-3 and Figures 2.5.C-19, 2.5.C-19A, 2.5.C-23, 2.5.C-23A, 2.5.C-24 and 2.5.C-24A will be updated in the FSAR annually for the first 5 years after the Unit 1 operating permit is issued. After the first 5 years, the data will be updated in the FSAR every 5 years.

Upon review of the data, should any trends become apparent which may have a significant effect on the plant site, the NRC will be notified and immediate steps will be taken to update the FSAR tables and figures.

Based upon the information in this submittal, Houston Lighting & Power considers this item " closed" If you should have any questions on this matter, please contact Mr. M. E. Powell at (713) 993-1328.
