Proposed Action

USGN proposes to drill and test six (6) production diameter geothermal resource exploration wells to be located on BLM administered public lands within the San Emidio Geothermal lease unit and leased to USGN in Washoe County, Nevada. The Site is generally located 12 miles south of Empire Nevada and 3.5 air miles west of State Highway 447, along the east side of the San Emidio Desert.

The proposed wells are located within Township 29 & 30 North, Range 23 East, sections 4, 9, 16 and 33, Mount Diablo Baseline and Meridian (MDM), on federal geothermal leases N­042707, N-074106, N-074196, & N-075233 (Site)(See Figure2) in two general areas of the Site (See Figures 3 and 4). DOE may provide funding for two(2) of the six (6) proposed production diameter wells or two (2) of the nine (9) private geothermal wells (covered in the cumulative impacts section of this EA) that would be drilled into San Emidio Geothermal resource area covered by the geophysical exploration project.

The proposed well sites were selected to explore a specific geophysical or geologic target. As USGN gains a better understanding of the geothermal resource, they may request to reposition drill site and their associated access within the project area, to meet data gathering needs. The Proposed Action includes:

  • Constructing, improving and/or maintaining 4,565 feet of access roads and 22,161 feet of temporary water pipelines as necessary to access and provide water to the well sites and testing of the wells;
  • Constructing six geothermal well drilling pads approximately 300 feet by 350 feet;
  • Drilling and completing a geothermal wells to a true vertical depth (TVD) of about 3,500 feet from each of the constructed drill pads;
  • Flow testing each completed well to obtain samples of the geothermal fluid and production information from the geothermal reservoir.

Conditions of Approval

Newly established fences associated with project should be flagged to minimize wildlife collisions.
