Incremental power plant and transmission line costs reassigned among tile project units in accordanc'l ~J.lth thp. ener-
gy credited to each site.
Total power costs assigned to each 1lllit including allocated joint costs, powerplant, transmission, and interest
during construction.

The estimated annual cost of operation, maintenance, and replacement assigned to each unit.

Average annual salable generation credited to each unit during 50 years of full operation.
Mill rate required to repay all costs allocated to power at each unit, including interest during construction, in
50 years of full operation with 2-1/2 % interest charged on the 1lllpaid balance.

The benefit-cost ratios shown are based on primary power benefits only but give consideration to the expected use-
ful life of facilities extending beyond 50 years by the present value of the estimated salvage after 50 years.
