Coyote Canyon South Geothermal Exploration Project EA for Geothermal/Exploration

General NEPA Document Info
Energy Sector Geothermal energy

Environmental
Analysis Type

EA

Applicant

Terra-Gen Power LLC

Geothermal Area

Coyote Canyon Geothermal Area

Project Location

Nevada

Project Phase

Geothermal/Exploration

Techniques

Exploratory Well
Comments This EA covers an extension of a previously approved exploration project, "Coyote Canyon Geothermal Exploration Project." Exploration results indicated the resource may be to the south of the already approved area. The BLM determined that this new EA would be needed to cover this new land area proposed for disturbance.

NEPA Schedule Comments
Since the Proposed Action is nearly identical to the originally proposed Coyote Canyon project, directly adjacent to the north of the Coyote Canyon South project area, the Proposed Action is being proposed as an expansion to that original exploration plan, and no additional resource issues were identified, separate consultation and coordination was determined to be unnecessary prior to the release of this EA. All agency feedback on that original project was incorporated into this EA.

Proposed Action

This Environmental Assessment (EA) analyzes the potential impacts associated with the proposed construction and testing of geothermal exploration wells, access roads, and ancillary facilities in Dixie Valley, as well as the expansion of and extraction of materials from two aggregate pits in Churchill County, Nevada (Figure 1, Project Location and Gravel Sources). Terra-Gen Power Dixie Development Company (TGP) proposes to expand a previously approved geothermal exploration area, originally called “Coyote Canyon”. This new proposal is to explore the geothermal resource potential of lands directly to the south of Coyote Canyon in three additional federal geothermal leases, referred to here as the Coyote Canyon South (CCS) lease area (Lease Area). The Lease Area is on federal lands managed by the United States (US) Department of the Interior, Bureau of Land Management (BLM) in Dixie Valley. The BLM is the lead agency for this EA in accordance with the National Environmental Policy Act (NEPA) (40 Code of Federal Regulations [CFR] Parts 1500-1508).The purpose of the geothermal exploration is to confirm that sufficient reservoir capacity is available to allow long-term production. This EA analyzes potential impacts from the proposed exploration and testing activities. The exploration activities and associated gravel pit expansions and extraction are referred to as the Proposed Action. The geothermal leases held by TGP for the CCS exploration project contain 7,588 acres, which comprise the Lease Area. TGP proposes to conduct geothermal exploration in a portion of the Lease Area called the Project Area. Figure 2, Proposed Action and Lease Area. Shows the Lease Area and Project Area. An operations plan to drill and test up to 15 explorations wells at the Project Area was submitted to the BLM, Stillwater Field Office (SFO) in August 2011. Revised Operations Plans were submitted in October 2011 and again in December 2011.In addition to the exploration drilling program, mineral material sales contracts would be required for aggregate material obtained from three BLM-managed gravel pits. Gravel extraction from one of the pits was analyzed under a previous NEPA document, and so this EA addresses impacts associated with the other two pits. Individual geothermal drilling permits would be issued separately from this document
