BLM Issues Right of Way for Geothermal Water Pipeline

The Bureau of Land Management (BLM) Ridgecrest Field Office has announced the issuance of a full force and effect right-of-way grant for the installation of a nine mile long, 20-inch water pipeline, to Coso Operating Company to deliver 3,000 acre feet per year of water to an injection well located at the Coso geothermal field.  The water will be used to replenish evaporated water from the Coso geothermal reservoir, and recapture as much as 70 megawatts of power, an amount sufficient to supply the needs of 50,000 homes in southern California.

The posting of this action initiates a 30 day public appeal period which will end on September 25, 2009. During this period, any person who participated in the environmental assessment process and believes they may be adversely affected by approval of the project may appeal this decision to the Board of Land Appeals, Office of the Secretary, in accordance with the regulations contained in 43 CFR Part 4.

The water extraction and delivery system underwent a five year study by Inyo County and the Bureau of Land Management. This resulted in the development of a hydrologic monitoring and mitigation plan (HMMP) between the Inyo County Water Board, Coso Operating Company, the BLM, and a private contractor. The plan was reviewed and analyzed by the U.S.Geological Survey (USGS) and the BLM's National Operations Center (NOC) and concluded that by implementing mitigation measures no significant impacts will occur to the Rose Valley aquifer.

The project site affects private land, Navy withdrawn land and public land managed by the BLM within Inyo County, California. The proposed pipeline and tanks includes an approximately 9 miles long by a 50 feet wide right-of-way encompassing a total area of approximately 55 acres. The pipeline primarily follows an existing roadway. Most of the pipeline will be buried except where geologic features force the pipeline above ground.

A revised environmental assessment, decision record, finding of no significant impact (FONSI), and right-of-way grant are available on-line at the BLM Ridgecrest Field Office's website:
