The University of Utah (Utah) would utilize DOE and cost share funds to address the overarching theme of uncertainty quantification and reduction for geothermal exploration, specifically through the development of Geothermal Play Fairways. Phase/Budget Period 1 of the FOA was reviewed by GFO-FOA0000841-001 on July 31, 2014. Utah was one of the initial awardees that have been selected to move into Budget Period 2 (BP2). This NEPA Determination is for BP2 activities only. Additional NEPA review will be required if the recipient is selected to move forward into Budget Period 3.

BP2 includes integration of existing magnetotelluric (MT), natural seismicity, fluid geochemistry, and well lithology data to analyze the likelihood of potential plays in southwestern Utah. New field work is involved and would include MT, passive seismic, gravity, helium isotope, well water and rock sampling, and geologic mapping with associated computer and laboratory analyses.
