SUBJECT:

ARIZONAPUBLIC SERVICE COMPANY MEETING JULY 21, 1999

Dear Mr. Levine:

This refers to the meeting conducted in the Region IVoffice on July 21, 1999, to discuss your steam generator replacement and power uprate project at Palo Verde Nuclear Generating Station Unit 2. This meeting, which was open to the public, was held in the NRC regional office located in Arlington, Texas.

During this meeting, your staff provided information on the schedule for these activities, th'e status of the project, and reviewed future activities. The meeting attendees are listed as Enclosure 1

~ Your presentation is included as Enclosure 2.

The NRC staff considered the meeting informative. Your presentation allowed us to gain a better understanding of your plans and progress for your steam generator replacement and power uprate project.

In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter and enclosures will be placed in the NRC Public Document Room.

Should you have any questions concerning this matter, we will be pleased to discuss them with you.
