Show APPENDIX VI VI-55 50 COLORADO RIVER STORAGE PROJECT Dominy's communication to the Secretary makes it plain that the offactling of Hoover impairment in kilowatt-hours and kilowatts has a second priority, at best, on Glen Canyon, Flaming Gorge, and Curecanti output. Arizona will be heard to insist that the offsetting of Hoover impairment must have first priority on that output to the extent that the Secretary cannot find lieu kilowatt-hours and kilowatts for purchase. Arizona will seek assurance of relief from extraordinary maintenance and replacement costs arising out of the Secretary's operating Hoover at less than rated head through exercise of his discretion. The coordination and integration of Lake Powell above elevation 3,490 and Lake Mead above rated head level (which we believe to be the intent) toward production of the greatest practical amount of power and energy is a worthy purpose which Arizona can endorse. Such coordination and integration implies inevitably the subordination of one or the other of the powerplants from time to time in the interest of achieving that maximum. This principle should be extended to provide for the free flow of credits and debits between the two plants so that both would assuredly share in the benefits of such coordination and integration. Principle 9 No comment. Principle 10 No comment. Parker and Davis The impact of storage project operations upon Parker and Davis receives no attention in Secretary Udall's proposals. Arizona accepts as inevitable a diminution in their output as a result of storage project filling operations. Unless relief is provided, rates must increase. Arizona holds that Parker and Davis are just as distinct from the storage project as though they were under another agency of Government, or private enterprises, and that the Secretary of the Interior has not the discretion to subordinate their payout (at the expense of their customers) to the uncertain rights of another project. Accordingly, we have continually urged the Bureau to recognize the Parker-Davis problem, and will continue to do so. Your recognizing our interest in these matters is appreciated. We assure you. again, of our willingness to work constructively with the Bureau in the development of fair solutions to its problems.
