Dear Mr. Ray:
The purpose of this letter is to announce our Maintenance Rule Baseline Team inspection at your San Onofre Nuclear Generating Station, Units 2 and 3, reactor facilities. We have scheduled this inspection for Decemoer 1 5,1997. The designated inspection team leader, J. E. Whittemore, of this office, will make arrangements with your staff to telephonically discuss the inspection plans in more detail.
The inspection objective will be to evaluate the effectiveness of your initial activities establishing baseline conditions to support compliance with the requirements of 10 CFR 50.65. The inspection will be conducted using Inspection Procedure 62706,
" Maintenance Rule." This inspection willinvolve a team of 6 8 NRC personnel.
The inspection team will require inforniation about your program and its implementation for their in-office preparation for the inspection. A description of the material that may be needed is in the enclosure to this letter. Our designated team leader will be contacting your staff and arranging for specific material to be available to the team by November 7, 4
1997.
If you have any questions concerning this inspection, please contact me at 817/860-8180 or Dr. Dale A. Powers, Chief, Maintenance Branch, at 817/860 8195.
