Aloha Hawaii County Council members,
The presentation slides by Waika Consulting feature three geothermal resource probability
maps from the Hawaii Play Fairway project. Based in the University of Hawaii at Manoa, the
scientists at the Hawaii Groundwater and Geothermal Resources Center (HGGRC) created
these maps for the project. These maps are in the project's third Geothermics journal article and
final report, and the original maps are below.

I commend HGGRC and its leader Dr. Nicole Lautze for advancing geothermal research in
Hawaii. I encourage you to further support them.
Thank you for your interest in geothermal,

Fig. t. Results of the DOE Phase I geothermal play fairway probability analysis for the State of Hawaii. Probabilities of a geothermal resource are colored. Areas with restricted land
access are shown in stippled and crosshatch patterns (e.g., National Park lands, protective conservation districts, and urban areas). Red boxes outline areas proposed for Phase 2 study.
White triangles indicate the calderas of the main shield voicanoes. White stars mark the locations of the Saddle Road well and Puna Geothermal Ventures (PGV). (For interpretation of the
references to colour in this figure legend, the reader is referred to the web version of this article.) r

Figure 32. Map showing the Pr>H across the State of Hawai'i, with ellipses highlighting locations where either slim hole drilling (yellow) or MT geophysics (white) is the
exploration step we recommend next. Encircled areas are approximations. On Hawaii Island, high -priority locations ace encircled, but an island -wide MT survey would be best
