4 NRC DOCKET 50-321 OPERATING LICENSE DPR-57 EDWIN I. HATCH NUCLEAR PLANT UNIT'l PROPOSED CHANGES T0-TECHNICAL SPECIFICATIONS Pursuant to 10 CFR 170.12 (c), Georgia Power Company has evaluated the attached proposed amendments to Operating License DPR-57 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, and does not require an environmental impact statement; c) The proposed amendment does not involve a complex issue, an environmental issue or more than one safety issue; d) The proposed amendment does involve a single safety issue, namely, the changing of ASME Section XI Category B Reactor Pressure Vessel weld examinations during the first 5-year inspection interval; e) The proposed change is therefore a Class III amendment.
