Haw. Code R. § 13-184-4
Beginning in 1983, and prior to the designation of any area as a geothermal resource subzone, the board shall first make or cause to be made a county-by-county assessment of those areas within the State which have potential for geothermal development activities. The methods to be used for making the assessments shall be left to the discretion of the board, provided that the board shall as a minimum consider the criteria set forth in section 13-184-6. The board may in its discretion base its methods for assessment on currently available public information. Where applicable, the board shall consider the objectives, policies and guidelines set forth in part I of chapter 205A, Hawaii Revised Statutes, and the provisions of chapter 226, Hawaii Revised Statutes.
The initial county-by-county assessments of areas with geothermal potential shall be revised or updated by the board at least once every five years beginning in 1988, or at any lesser interval of years at the discretion of the board.
