NEPA Proposed Action Ormat is proposing to conduct geothermal e
Ormat is proposing to conduct geothermal exploration projects in Gabbs Valley Nevada. The proposed action consists of exploration drilling, drilling temporary water wells, road construction and maintenance, (both on lease and off lease), and develop four gravel pits for aggregate to be used for proposed actions. The proposed action includes: *Drilling up to 58 TGHs (31 at Gabbs Valley and 27 at Dead Horse Wells), each to a maximum depth of approximately 1,000 feet, and measuring the temperature profile in each; *Constructing up to 38 observation well drill pads (25 at Gabbs Valley and 13 at Dead Horse Wells) at the sites designated as TGH/Observation/Exploration Well sites. Drilling and completing each observation well to a depth of about 3,000 feet from each of the constructed observation well drill pads, *Constructing up to 38 exploration well drill pads at the sites designated as TGH/Observation/Exploration well sites (by enlarging the previously constructed observation well pads or constructing new drill pads on an undrilled site). Drilling and completing an exploration well to a depth of about 7,000 feet at each of the constructed drill pads; *Flow-testing each observation and exploration well to obtain samples of geothermal fluids and to collect aquifer information from the geothermal reservoir. Aquifer testing would define aquifer characteristics and would predict the effects of pumping on existing wells as well as determine potential dewatering of shallower aquifers and springs in the geothermal unit areas. During testing, all geothermal fluids would be discharged into the well pad reserve pits. After more than one well has been completed, further flow testing may be conducted by running a temporary pipeline between wells and flowing the fluids from one well into the other well; *Constructing, improving or maintaining access roads (both on lease and off lease), as proposed; *Drilling temporary water wells at one or more proposed drill site; and *Develop three material sites for the Gabbs Valley Project and one material site for the Dead Horse Wells Project to supply aggregate for road and drill pad construction and maintenance.

*If previously unrecorded cultural resources are encountered during grading or other surface-disturbing activities, all grading or other surface-disturbing activities at the location of the discovery would cease within 100 meters/330 feet of the discovery, and the BLM would be notified. No surface disturbing activities would be allowed until the BLM Authorized Officer issues a Notice to Proceed (NTP) based upon the evaluation, mitigation, as necessary, and the acceptance of a summary description of the fieldwork performed for the discovery situation. *The locations of the historic properties will be provided to Ormat and flagged for avoidance. If avoidance of currently documented historic properties is not possible a resolution of adverse effects would be followed as defined in 36 CFR 800.6. *An archaeological monitor should be present during any ground disturbing activities. They should have the authority to halt all earth moving activities in the area of the discovery if prehistoric or historic artifacts are discovered until the find can be assessed. In the event of an inadvertent discovery all construction would cease within 100 meters/330 feet of the discovery.

*Ormat would inventory and monitor existing wells in the geothermal leases to determine their suitability for use as monitor wells. Where necessary, monitor wells would be installed at appropriate locations and depths to monitor geothermal exploration drilling. *Ormat would collect standard aquifer test data during and after well testing from completed cased wells. Data collection would include but not be limited to static water levels, well drawdown, and other data that characterizes the aquifer(s) and that can be used to predict future scenarios as well as determine boundary affects. The data collection applies to both unconfined and confined aquifers. *Ormat would collect baseline hydrologic data from both geothermal lease units. Data would include ground and surface water temperature, chemistry, groundwater elevations, and surface water flows (springs). Data would be collected to support and expand upon the required hydrologic monitoring program.
