. PROPOSED DETERMINATION OF /J1ENDt1ENT CLASS Pursuant to 10 CFR 170.12 (c), Georgia Power Company has evaluated the attached proposed amendment to Operating Licenses DPR-57 and NPF-5 and has determined that:

a) The proposed amendment does not require the evaluation of a new Safety Analysis Report or rewrite of the facility license; b) The proposed amendment does not contain several complex issues, does not involve ACRS review, or does not require an environmental impact statement; c) The proposed amendment does not involve a complex issue, an environ-mental issue or more than one safety issue; d) The proposed amendment does involve a single issue; namely, the replacement of specifications on RPS MG sets with specifications on the RPS power supply monitoring systems and appropriate sur;eillance requirements; e) The proposed amendment is therefore a Class III amendnent for Unit 2 and a Class I amendnent for Unit 1.
