request for appropriations for the construction of the third power-
plant is made, by computing the average interest rate payable by the 
Treasury on all interest-bearing marketable public debt obligations of 
the United States then outstanding, which, upon original issue, had 
terms to maturity of fifteen years or more, and by adjusting such 
average rate to the next lowest multiple of one-eighth of one per 
centum. 
(b) Construction of the third powerplant may be undertaken in 
such stages as in the determination of the Secretary will effectuate the 
fullest, most beneficial, and most economic utilization of the waters of

present annually to the President and the Congress a consolidated 
financial statement for all projects heretofore or hereafter authorized, 
including the third powerplant at Grand Coulee Dam, from or by 
means of which commercial power and energy is marketed through the 
facilities of the Federal Columbia River power system and for all 
other projects associated therewith to the extent that the costs of these 
projects are required by law to be charged to and returned from net 
revenues derived from the power and energy, or any power and energy, 
so marketed, and he shall, if said consolidated statement indicates that 
the reimbursable construction costs of the projects, or any of the 
projects, covered thereby which are chargeable to and re'^urnable 
from the commercial power and energy so marketed are likely not to 
be returned within the period prescribed by law, take prompt action 
to adjust the rates charged for such power and energy to the extent

necessary to assure such return.
