The U.S. Department of Energy (DOE) is proposing to provide federal funding to the University of Hawaii at Manoa 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. Previous NEPA Determinations (GFO-FOA0000841-001 and GFO-0006729-002 through 005) reviewed Budget Periods (BP) 1, 2 and a few tasks in BP3 of the project. Activities in Task 22 are independent of and have scientific utility separate from the planned drilling on Lanai, therefore DOE is reviewing this task separately within this NEPA determination. All remaining BP3 tasks will require further NEPA review.
