Proposed Action

Standard Steam proposes the drilling of 18 TGHs and the construction of access routes on BLM-administered lands covered by federal geothermal lease numbers UTU-86778, 86779, 86780, and 86781. The project is located just south of Fish Springs Flat in Juab County, Utah (Figures 2-1 and 2-2).

No right-of-way grants would be required since construction of access routes would be authorized under an approved NOI. ROW routes to two holes that would be located on State of Utah Leases would also be constructed. These would be permitted separately with the state of Utah; however, construction of the access routes is evaluated in this EA.

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

Livestock (sheep) grazing will occur in the area of the project from 12/1/09 through 3/31/10. The project may interfere with grazing use if work occurs during this time. Overland travel and travel on unimproved roads when soils are wet and muddy should be avoided.

   
Wilderness
"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 Fish Springs WSA is located north of Sandy Pass road. The project area is located approximately 1 ½ miles south of this road and no impacts are anticipated due to this seperatiion.

   
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.

"See Technical Report." A Rangeland Health Assessment was completed for the Swasey Knoll Allotment in May 2002. This allotment was determined to be in compliance with the standards of rangeland health and in conformance with the guidelines for grazing management.

   
BLM Sensitive 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.

Sand-loving buckwheat occurs on sandy soils within and surrounding the proposed wells and access roads areas. Constructing well pads and access roads may impact this plant. An effort should be made to either avoid surface disturbance by relocating access roads or well pads, and/or mitigate impacts to this plant and potential habitat areas. Special Status Species such as dark kangaroo mouse (Micrdipodops megacephalus) and grasshopper sparrow (Ammodramus savannarum) have a likelihood of occurring within the area of the proposed action. The short-eared owl (Asio flammeus) was observed near the project site. Conservation measures presented in the applicant biological report and within the BLM Fish and Wildlife Biological Evaluation are to be applied to avoid/minimize impacts to these species.
