EA at Patua Geothermal Area for Geothermal/Well Field

EA for Development Drilling and Well Testing at Patua Geothermal Project Phase II for Geothermal/Well Field

Proposed Action


GRI is proposing to design, construct, and operate geothermal well pads and wells, geothermal fluid pipelines, and their associated access roads. These facilities would be connected to the previously proposed geothermal power plant for the Patua Phase I project or to a new nominal 60MW net geothermal power generation facility, to be located on one of two privately owned sections of land within the Unit. The power plant could be located adjacent to the existing Patua Phase I power plant, or in Section 29, T20N R26E. The elements of the proposed action include:

  • Reclamation‐managed lands
    • Drill 3 new temperature gradient holes (TGHs) (no vegetation removal required)
    • Construct 14 new well pads and drill multiple wells (57 acres disturbance)
    • Construct approximately 10.5 miles of geothermal fluid pipeline and access roads (159 acres of temporary disturbance and 159 acres of permanent disturbance)
    • Construction of 1.51 miles of new transmission line if a power plant is built south of Alt 50 (18.3 acres disturbance, assuming a 100‐foot corridor)
  • BLM‐managed lands
    • Drill 1 new TGH (no vegetation removal required)
    • Construct five new well pads and drill multiple wells (22 acres disturbance)
    • Construct approximately 2.2 miles of geothermal fluid pipeline and new access road (40 acres of temporary disturbance and 40 acres of permanent disturbance)
  • Private land
    • Construct approximately 1.1 miles of new access road and geothermal fluid pipeline (33 acres of temporary disturbance and 33 acres of permanent disturbance)
    • Construct nominal 60 MW net geothermal power generation facility and generation substation (29 acres permanent disturbance)
    • Construction of 0.8 miles of new transmission line if a power plant is built south of Alt 50 (9.7 acres permanent disturbance, assuming a 100‐foot corridor plus 32 acres of temporary disturbance for staging)
