Subject:

Palo Verde Nuclear Generating Station (PVNGS)

Units 1, 2 and 3, Docket Nos. STN 50-52815291530 Supplement to Amendment Requests Associated with Power Uprate - New Retyped Technical Specification Page The amendments requested in References 1 and 2 contained changes to Technical Specification (TS) Table 3.7-1. These amendment requests are currently under review by the NRC staff. On July 7, 2005, the NRC issued Amendment No. 155 to the PVNGS Units 1, 2 and 3 Operating Licenses which included changes to TS Table 3.7-1.

The enclosure to this letter provides a retyped TS page 3.7.1-4 which contains Table 3.7-1 that is based on Amendment No. 155. The retyped page reflects a combination of the changes requested in References 1 and 2. In Reference 2, APS requested concurrent approval of both requests because they are both related to power uprate.

There are no commitments being made to the NRC in this letter.
