ATTAC E NT 2 W C DOCKET 50-321 OPERATING LICENSE DPR-57 EDWIN I. HATCH NUCLEAR PLANT UNIT 1 SECONDARY CONTAItNENT TECINICAL SPECIFICATION CHANGE PROPOSAL Pursuant to 10 CFR 170.22, Georgia Power Company has evaluated the attached proposed amendment to Operating License DPR-57 and has determined that:

a. The proposed amensent does not require evaluation of a new Safety Analysis Report and rewrite of the facility license;

b. The proposed amsndment does not require evaluation of several complex issues, involve ACRS review, or require an environmental impact statement;

c. The proposed amen &ent does not involve a complex issue or more than one environmental or safety issue;

o. The proposed amendment does involve a single safety issue, namely, the addition of a Limiting Condition for Operation without secondary containment integrity.

e. The proposed amen &ent is therefore a Class III amen &ent.
