Dear Commissioners and Staff:

In Reference 1, Pacific Gas and Electric Company (PG&E) submitted License Amendment Request (LAR) 20-03, to propose revisions to the technical specifications and license conditions to reflect the permanently defueled condition.

In Reference 2, PG&E supplemented LAR 20-03 to request additional changes. The purpose of this submittal is to provide the title pages for the Diablo Canyon Power Plant (DCPP) Units 1 and 2 facility operating licenses (FOLs) to remove reference to the term "operating," and update the marked up and clean copies of a page of the FOLs to make an editorial correction to License Condition 2.C.(2).

In Reference 2, PG&E provided an updated marked up copy of the FOLs for DCPP Units 1 and 2. Enclosure 1 provides a marked up copy of the DCPP Units 1 and 2 FOLs title pages and replaces the corresponding marked up pages of Reference 2, Enclosure, Attachment 1, for License Condition 2.C.(2). Enclosure 2 provides a clean copy of the DCPP Units 1 and 2 FOLs titles pages and replaces the corresponding pages in the clean copy of Reference 2, Enclosure, Attachment 2, for License Condition 2.C.(2). Refer to Enclosures 1 and 2 for additional details.
