Title: Buffalo Flat Service 115-KV Transmission Project : Environmental Assessment.

Abstract

The US Air Force has sited a radar transmitter at Buffalo Flat, near Christmas Valley, Oregon. This report discusses the environmental impacts of providing the electrical service for the installation. A 115 kV power transmission line will be built between LaPine and Buffalo Flat. Route alternatives as well as design alternatives are discussed. (ACR)

  • BPA, in conjunction with Midstate Electric Cooperative (Midstate), proposed to construct two sections of a new 115-kV transmission line in central Oregon: one section from BPA's LaPine Substation to Midstate's Fort Rock Substation (BPA), and the other from Fort Rock Substation to the proposed US Air Force radar transmitter site at Buffalo Flat (Midstate). The proposed line would be a total of about 74 miles long, and of either wood or steel single-pole construction; it would parallel existing corridors and/or roads for much of the distance. 23 refs., 6 figs., 5 tabs.
  • The Western Area Power Administration (Western) proposes to remove two existing 34.5-kV transmission lines connecting Shoshone Powerplant-Heart Mountain Switchyard-North Cody Substation and replace them with a new 69-kV line. The new 69-kV line would connect the proposed Buffalo Bill Switchyard to North Cody Substation. An abandoned 69-kV line connecting Shoshone Powerplant and Heart Mountain Switchyard would be rebuilt and returned to service between Buffalo Bill Switchyard and Heart Mountain Switchyard. This action is proposed because the existing lines, built between 1922 and 1941, have reached the end of their useful life due to their deteriorated condition. In order to providemore » for the increased generation of the Shoshone and Buffalo Bill powerplants, the capacity of the existing transmission system into Buffalo Bill Powerplant must be upgraded to prevent overload and inevitable system interruptions. Reliability of service in the area would be improved by replacement of the existing deteriorated lines with new construction. 25 refs., 7 figs., 1 tab.« less
  • At present, the only transmission line serving the City of Roseville is operated by Pacific Gas and Electric Company (PG and E), which serves the City's Berry Street substation with a 60-kV circuit from the company's own Atlantic Street substation. Western pays wheeling charges to PG and E for use of their lines to deliver power to its customers which cannot be served directly. PG and E has informed Roseville that additional system facilities are required to meet the City's firm transmission requirements in excess of 69 megawatt peak. They proposed to build a new 230-kV line and transformer bankmore » at a cost of $10.9 million which the City would have to pay, in addition to the wheeling charges Western would be charged to use the PG and E line. The City's preferred alternative is to have Western construct a direct 239-kV service from its Elverta substation to the Berry Street substation. This would save the city money in construction capital cost, result in more transmission capacity and eliminate the present wheeling costs charged to Western. Mitigation recommendations are included.« less
  • A brief summary of the environmental impacts which would result from the construction and operation of the proposed 115-kV transmission line from Alder Dam to the town of Elbe is presented. Mitigation measures which would be included in the design, construction, and operation of the facility to minimize these impacts are also listed. The impacts identified are not significant because none are high in intensity or extent, and most would be minimized or avoided by the mitigation measures integrated into the proposal. This action would not establish a precedent for future actions with significant effects. No other development activity ormore » transmission project is planned or being developed as a result of, or in relation to this proposal. Unless additional impacts which are significant are identified during public and agency review of this document, or as a consequence of Lewis County PUD's construction of the Elbe Substation, BPA will not consider this project to be a major Federal action significantly affecting the quality of the human environment. Therefore, an Environmental Impact Statement will not be required.« less
  • Bonneville Power Administration (BPA) provides power to Surprise Valley Electrification Corporation (SVEC) in Modoc County, California. BPA uses PacificCorp's substation and transmission facilities between Alturas and Canby, California to transfer power to SVEC's Canby Substation. In the next year, SVEC expects increased industrial, agricultural, and residential electric loads on their 69-kV transmission system south of Canby. SVEC's substation can accommodate only about 10 percent of the expected additional electric load. BPA's proposed action is intended to meet SVEC's increasing electric load. BPA proposes to meet SVEC's increasing energy load by tapping into BPA's existing BPA Malin-Warner 230-kV transmission line, andmore » building an 7.9-mile transmission line to a new BPA substation. BPA proposes to build the new substation next to the west side of SVEC's Canby Substation (Figure 1). This new substation will allow SVEC to move the additional power over their existing transmission or distribution lines. This report is the environmental assessment of the potential impact of the proposed project. The assessment determined that no environmental impact statement'' is not required.« less
