HATCH NUCLEAR PLANT UNIT 1 SECONDARY CONTAIf44ENT TECMICAL SPECIFICATION CHANGE PROPOSAL l Pursuant to 10 CFR 170.22, Georgia Power Company has evaluated the attached proposed amenchent to Operating License DPR-57 and has determined that:

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

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

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

d. 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 amendment is therefore a Class III amendment.
