GLEN CANYON STORAGE UNIT; ARIZONA Work on the prime contract for construction of the 700-foot-high concrete arch d$m and the 900,000ckilowatt powerplant was at a virtual standstill from July 6, 1959, to January 4, 1960, due to a general strike of the contractor's employees.

Meetings were held with prospective preference cus- tomers and private 'utility groups for the purpose of discussing and resolving technical problems relative to the location of lines and operating characteristics of the transmission system. In response to a presentation of a tentative proposal for transmission lines, there was received by the Bureau of Reclamation on October 1, 1959, a plan from si~ electric companies under which they would con- struct certain elements of the transmission system. The utilities, in April 1960, quoted 1fheeling charges applicable under the foregoing proposal. , The Bureau devised a possible all-Federal tran~mission system "S the basis for establishment of rate schedules for project power and as a yardstick to evaluate the proposal of the utility companies. The Secretary of the Intehor approved this yardstick system on May 17, 1960. At the same time he also approved the area within which the power would be marketed and the broad criteria under which it would be marketed. On the basis of these approved criteria, compilation of
