Proposed Action

Ormat proposes to relocate 3 drill sites previously analyzed in BLM EA: DOI-BLM-NV-C010-0006-EA and approved under Decision of Record signed on January 13, 2010. The reason for the relocation is a new interpretation, by Ormat, of their geophysics. This action would be conducted within the previous cultural survey areas.

The 2 TGH/GDP's are being moved within the previous area surveyed for and approved for TGH/Observation well sites.

For the TGH well, Ormat is proposing to relocate TGH 36-18 to TGH 75-29. They propose a minimal impact program that would consist of a track mounted drilling rig, a rubber tired off-road crawler to carry pipe, water and fuel, a backhoe to dig the reserve pit, a rubber tire pipe buggy, and an ATV to move personnel to the site. No pad construction is proposed, but a small reserve pit will be required and there will be impacts to vegetation of approximately 0.5 acre, along with a cross country road of 2500'x 15' equal to 1 acre for a total of 1.5 acres. The previous proposal permitted a constructed pad.
