Proposed Action


Ormat proposes to evaluate the geothermal resources that potentially exist within the Lease Area by constructing up to 20 well pads and drilling one of each of the three different types of geothermal exploration wells on each pad: temperature gradient wells, observation wells, and production wells. Therefore a total of 60 geothermal exploration wells may be drilled as part of the Proposed Action. Each well pad would be permitted to accommodate the maximum approximate size necessary for the construction and operation of a production well, the largest of the three types. The drilling of each well type may not necessarily occur on each well pad, only one well of each well type would be drilled on any single well pad, and not all well pads may be utilized or developed. While each pad site would be permitted to accommodate a production well, well pads would be constructed only to the extent necessary to accommodate the well type(s) situated on it. If Ormat initially drills a temperature gradient well or observation well on a well pad, that well pad would not be expanded to full permitted size unless a production well is later drilled on it. Under no circumstances would a well pad be expanded to a size greater than that needed for a production well. Specific details about the design and layout of well pads are provided in Section 2.1.2.1.

In support of the geothermal exploration drilling activities, Ormat also proposes to construct new gravel access roads and utilize and repair existing roads for access to the Project Area. Gravel would be obtained from an existing mineral material site that Ormat would expand and from a new mineral material site that Ormat would construct (Figure 2). Additionally, Ormat proposes to drill up to two groundwater wells on one or two of the proposed well pads or at the proposed new gravel source area. Therefore, a total of 62 wells may be drilled, including 60 geothermal exploration wells and 2 groundwater wells. Ormat would install an above-ground water distribution pipeline, within the project boundary as described in this EA, between the groundwater wells and well pads actively being drilled. The pipeline would be located along the sides of proposed access roads and on well pads, and would not require additional surface disturbance. The water distribution pipeline system would require prior BLM approval of a Sundry Notice to authorize construction of the pipeline. Ormat would also construct or install the necessary ancillary facilities in support of drilling activities, including a temporary personnel “camp” for active drilling crews.
