OPERATING LIMITING CONDITION FOR OPERATION 3.8.1.1 As a minimum, the following A.C. electrical power sources shall be OPERABLE:

a. physically independent circuits between the offsite transmission M d network and the onsite Class lE distribution system consisting of cith :
1. Two 500 Ky offsite power circuits, :r x xxxnr3 and .
2. The 69 Kv SMECO offsite power circuit described in the January 14, 1977 Safety Evaluation y = c O ' ;ff:it: p u r ci, L it, and
b. Two separate and independent diesel generators (one of which may be a swing diesel generator capable of serving either Unit 1 or Unit 2) each with:
1. Separate day fuel tanks containing a minimum volume of 375 gallons of fuel, t
2. A common fuel storage system consisting of two independent storage tanks each containing a minimum volume of 18,250 gallons of fuel, I

, and

3. A separate fuel transfer pump.
