The Comaissi6n's staff has reviemd the information provided in the applicant's submittal, and we conclude that the factors discussed above are reasonable and constitute good cause for delay; and the extension of construction of Unit 1 for 2,months and of Unit, 2 for 4 onnths is justifiable.

As a result of the staff's review of the Final Safety Analysis Report to date, and considering the nature of the delays, we have identified no area of significant safety considerations in connection with the extension of the construction permit completion dates for the Diablo Canyon nuclear Power Plant, Units 1 and 2.

The assessment of potential environmental impacts associated with site preparation and.the construction of Units 1 and 2 of the Diablo Canyon Nuclear Power Plant were addressed in the Final Environmental Statement (FES) issued in May 1973.

Since the construction of Unit tto.

1 is essentially complete except for installation of the modifications and construction of Unit 2 is approximately 965 complete, essentia'lly all construction impacts have occurred.

The continuation of a construction work force on site for an additional 4 months is not expected to have any increased impact on the local environment or the nearby comunities.

The staff has determined that the extension of time for completion of work shown in Construction Permit No. CPPR-39 from April 30, 1979 to June 30, 1979 and in CPPR-69 from October 31, 1979 to February 29, 1980, is an administrative action since it does not alter impapts described in the FES or create new impacts not previously addressed in the statement.

Having made this determination, the Commission" has concluded, pursuant to 10 CFR Part 51.5(d) (4), that an environmental statement, negative declaration or environmental im<pact appraisal need not be prepared in connection with the issuance of this extension of time.

The staff finds that this action does not involve a significant hazards consideration, that good cause exists for the issuance of an Ordei extending the completion dates, and that an environmental statement, negative declaration or environmental impact appraisal need not be prepared in connection with the issuance of such order.
