Proposed Action

Exergy, Inc (Exergy), proposes to construct and operate a 6-megawatt (MW), advanced binary, geothermal power plant. The development of this power plant includes geothermal production and injection wells, as well as ancillary facilities [such as on-site access road(s) and electric transmission lines interconnected to existing geothermal power plants]. The proposed site to be developed is approximately 16 kilometers (km) [(10 miles (mi)] southeast of Reno in Washoe County, Nevada. The proposed geothermal power plant and associated components, using the KCS 11 technology, are known as the Kalina Geothermal Demonstration Project (KGDP).

The proposed KGDP would be located on a private leasehold known as the Harvey (formerly "Giusti") parcel within the jurisdiction of Washoe County. The Harvey parcel is approximately 24 hectares (ha) (60 acres) in Section 29 of Township 18 North, Range 20 East.


Data Completion Notes

5/21/2014: added Decision Date based on signature date on final page of the EA. For the convenience of future reviewers, the latest date I can find on the 1998 application attachments is 5/21/1998. Many of the application documents for the 1993 EA application appear to be dated Nov/Dec 1993. MB

Social Values
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

As demonstrated by the statistical data provided in Section 3.1.1, the Reno/Sparks MSA is not predominantly comprised of minority or disadvantaged groups.

   
Economic Values
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

The estimated peak work force during construction is estimated to be 75 to 100 workers. Preference would be given to local companies. Therefore, the project is not expected to generate a major influx of new employees.

   
Lands and Realty
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Implementation of the proposed action would be consistent with the existing Washoe County land use plan which designates the use of the project site for geothermal development.

   
Geology and Minerals
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Approximately 3.4 ha (8.4 acres) would be cleared and graded during site preparation. These impacts are not expected to effect the on-site geology (i.e., change geologic substructures).

   
Soils
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Approximately 3.4 ha (8.4 acres) would be cleared and graded during site preparation.

proposed  
Vegetation
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Permanent impacts to vegetation in the study area would consist mainly of loss of upland open forest and, to a lesser extent, sagebrush from construction of the proposed action.

  imposed
Wildlife Resources
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Because wildlife occurring in the existing habitats are relatively low in abundance and diversity, construction activities would be expected to result in removing or displacing low numbers of common and characteristic animals and habitat features.

   
Special Status Species
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Potential impacts to Steamboat buckwheat and Altered andesite buckwheat due to construction of activities associated with this project are described in a biological assessment.

  imposed
Cultural Resources
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Although the Sinter Quarry occupies roughly two-thirds of the project area, the distinct loci being recommended for eligibility on the NRHP consist of debris that is scattered widely throughout the individual sites.

  imposed
Public Health and Safety
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Potential impacts to public health and safety associated with the proposed action would be limited to upset conditions resulting from accidental releases from on-site ammonia storage tanks and transferring geothermal brine at the power plant.

  imposed
Water Quantity
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Short-term exposure of the disturbance area may effect surface runoff. Since construction would only last a short term (approximately 14 months), significant impacts to absorption rates, drainage patterns, surface runoff, or water quality is not expected.
