Show Various items of equipment for installation in the dam and powerplant, such as penstocks and outlet pipes, radial gates and gate hoists, turbines, and cranes, were in the process of manufacture and fabrication at the close of the fiscal year. Navajo Unit-New Mexico At June 30, 1960, progress by the prime contractor for construction of the 405-foot-high earth and rock fill dam on the San Juan River in the northwestern part of New Mexico was well ahead of schedule, with 58 percent of work performed in 42 percent of the time allowed by the contract. Diversion of the river through the main outlet-works tunnel was accomplished and some 12 million cubic yards of fill material had been placed in the dam by the end of the fiscal year. Equipment items such as outlet gate valve, outlet pipe, steel walkway, and intake bulkhead and embedded metalwork for the intake structure of the outlet works were in the process of manufacture and fabrication. Transmission Division During fiscal year 1960, further studies were made on the overall plan for the power transmission system within the Upper Colorado River Basin. Meetings were held with prospective preference customers 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 six electric companies under which they would construct certain elements of the transmission system. The utilities, in April 1960, quoted wheeling charges applicable under the foregoing proposal. The Bureau devised a possible all-Federal transmission system as 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 Interior 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 field data for evaluation of the proposal of the utility companies was essentially completed at the end of the fiscal year. As a result of several meetings and discussions between the Bureau and interested parties, there was general agreement that the 115 |
