EA-1810: Finding of No Significant Impact

San Emidio Geothermal Exploration Project, Washoe County, Nevada

The U.S. Department of Energy proposed to authorize the expenditure of federal funding to U.S. Geothermal Nevada, Inc. (USGN) to validate the use of innovative geothermal technologies to locate large aperture fractures (LAFs) and to drill two (2) production diameter geothermal wells on BLM administered Public lands in the San Emidio resource area. The innovative geothermal technologies would include using a three-component long-offset surface seismic survey, permanent scatter synthetic aperture radar interferometry (PSInSAR) and structural kinematic analysis to locate and map the LAFs. The U.S. Department of Interior, Bureau of Land Management, Black Rock Field Office (BLM) is the lead federal agency with DOE as a cooperating agency.
