Proposed Action

Ormat proposes to evaluate the geothermal resources that potentially exist within the Drum Mountains and Whirlwind Valley lease areas (Figure 2) by constructing well pads at each proposed location, and drilling up to one temperature gradient well, one observation well, and one production well on each site. The primary objective for the geothermal exploration projects is to gain an understanding of the characteristics of geothermal resources within the two lease areas.

The proposed action consists of:

  • constructing up to 11 geothermal exploration well pads at the Drum Mountain lease area and as many as 16 geothermal exploration pads at the Whirlwind Valley lease area;
  • constructing access roads and with occasional vehicle turnout spaces;
  • constructing aggregate (gravel) source areas for gravel surfacing of well pads and roads;
  • drilling and completing geothermal exploration wells;
  • flow testing select observation and productions wells as applicable;
  • drilling non-potable water wells on the well pads or gravel source areas within the Drum Mountains and Whirlwind Valley lease areas; and,
  • constructing temporary personnel camps during drilling activities at either or both lease areas.

The above list is representative of the major components of the proposed action and is not necessarily inclusive of all activities and operational procedures that would occur if the proposed action were implemented. Similarly, the above list includes several activities and/or components that may not necessarily be performed or constructed, depending on data collected during operations. The following subsections detail the specific construction and operational procedures that comprise the proposed action and are the subject of the analysis of this EA.
