ATTACHE NT 2 NRC DOCKET 50-366 OPERATItG LICENSE ffF-5 EDWIN I. HATCH NUCLEAR PLANT UNIT 2' DETERMINATION OF AEPOENT CLASS Pursuant to 10 CFR 170.12 ~ (c), Georgia Power Company has evaluated the attached proposed amendment to Operating License iFF-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, and does not require an environmental impact ste':ement; -

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, a one time extension of the grace period for calibration of the LPRMs; e) The proposed amendment is therefore a Class III amendment.
