The U.S. Department of Energy (DOE) is proposing to provide federal funding to the University of Hawaii to address the overarching theme of uncertainty quantification and reduction for geothermal exploration, specifically through the development of Geothermal Play Fairways. A play fairway analysis defines levels of uncertainty with respect to the presence and utility of geothermal system elements, and translates them into maps to high grade the geographic area over which the most favorable combinations of heat, permeability, and fluid are thought to extend. A previous NEPA Determination (GFO-FOA0000841-001; CX A9; 07/31/14) reviewed Phase/Budget Period 1 activities and a second NEPA Determination (GFO-0006729-002; CX A9, B3.1, B3.6; 04/25/16) reviewed Budget Period 2 (BP2) but restricted Task 10 pending further review. This NEPA Determination is to review the remaining Task 10 activities.
