They also include the project 1 s annual <br />operation, maintenance, and replacement costs and a prorata share of the <br />costs of regulatory features of the ColoradO River Storage project. Costs <br />of the storage project I s regulatory features are paya'ule by revenues of <br />the storage project. For purposes of benefit-cost analysia, however, they <br />are assigned to future water-consuming projects in the upper basin since <br />development of such projects is considered to be dependent on the river <br />regulation that would be provided by the storage project. Computation of <br />the average annual equivalent costs is shovtl in the following tabulation. <br /> <br />31 <br />
