Bureau of Land Management's Decision Record and Environmental

Attachment E
CONDITIONS OF APPROVAL FOR GEOTHERMAL UTILIZATION
The geothermal wells would be cased with steel to a depth well below the shallow ground
water reservoirs. The casing would be cemented into the ground to prevent the loss of any
geothermal resource into, and prevent the contamination or mixing of, any shallow
ground waters by the geothermal production or injection fluid. The Underground
Injection Control Permit required for injection program from the Nevada Department of
Environmental Protection-Bureau of Water Pollution Control (NDEP-BWPC) would
require that the injection program be designed and monitored to prevent degradation of
underground sources of drinking water due to the geothermal fluid injection practices.
Should this monitoring program demonstrate that adverse impacts to the hot springs may
be occurring, the unit operator shall, as required by the BLM authorized officer,
immediately retain a qualified third-party consultant, acceptable to the BLM authorized
officer, to review the collected data and to evaluate the collected data and recommend
reasonable mitigation measures. A group consisting of the applicable stakeholders,
including the current holder of water rights from the hot springs, if any, would be
convened to review the recommended measures.
• WASTES (HAZARDOUS AND SOLID)
Mitigation Measure:
Absorbent pads or sheets would be placed under likely spill sources.
• VISUAL RESOURCES:
Mitigation Measure:
All drill rig and well test facility lights would be limited to those required to safely conduct
the operations, and would be shielded and/or directed in a manner which focuses direct light
to the immediate work area.
Permanent facilities within the Jersey Valley Unit Area would be painted a color, subject to
approval by the authorized officer, which would blend with the landscape (likely covert
green). Prior to painting, Ormat would contact the Mount Lewis Field Office lead.
Permanent facilities within the Jersey Valley Unit Area and will have lighting limited to
those required to safely conduct the operations, and would be shielded and/or directed in a
manner which focuses direct light to the immediate work area.
The substation at the north end of the transmission line corridor would be painted a color,
subject to approval by the authorized officer, which would blend with the landscape. Prior to
painting, Ormat would contact the Mount Lewis Field Office lead.
