EA at Coyote Canyon Geothermal Area for Geothermal/Power Plant

Coyote Canyon Utilization Project EA for TGP for Geothermal/Power Plant

Proposed Action

TGP proposes to construct a 70 megawatt geothermal power plant and associated production/injections wells, pipelines, and support facilities. Power generated by the plant will be delivered to an existing transmission line via a short tie-in line from the power plant.

  • Wells would be grouted and cased so that flood water could not penetrate if well pads

are inundated.

  • A hydrologic evaluation and monitoring plan would be submitted to the BLM for approval prior to drilling and implemented once approved.
  • Monitor flow and pressure of pipelines and well pumps.
  • Install pipeline valve shutdown features.
  • Piping would be routinely maintained to ensure reliability and integrity, and would be predominantly located above ground, so that leaks, if any, can be visually identified more quickly than with buried piping.
  • Engineer and construct pipes to current industry standards to handle anticipated temperature, pressure, and corrosion potential of the fluids being transmitted.
  • Condensate “pots” would be installed in numerous locations under each new production pipeline to minimize the chance for inadvertent leaking of geothermal fluid

from the pipelines into area soils.

  • A BLM-approved grouting and casing program for well construction would be implemented to prevent water quality effects on groundwater during or after well

installation.

  • Borehole geophysics analyses (cement bond logs) would be conducted to document that well-casing grouting activities provide an effective seal, isolating the geothermal aquifer from shallow alluvial aquifers.
