Nevada Geothermal Power Company (NGP) would analyze the energy potential of the Crump Geyser geothermal resource in Southern Oregon by gathering data on the geothermal system. Phase 1 (Tasks 1.0, 2.0, and 4.0) of this project was previously approved by GFO-10-164 on February 8, 2010 with a CX A9 and B3.1. Additional information was submitted in regards to Phase 1 (Task 3.0), with a resultant approval by GFO-10-164.001 on August 27, 2010 of Phase 1 (Task 3.0) and Phase 3 (Task 14.0) with a CX A9 and B3.1. NGP submitted additional information and a new Statement of Project Objectives (SOPO) which modified the tasks to be completed in Phase 2. A NEPA Determination (GFO-0002835-003) was completed for all remaining project activities on June 15, 2011. In the last SOPO NGP had planned to drill two slim wells at locations that had already been reviewed for permitting and therefore both locations were approved through the NEPA Determination but since then an additional task and subtask has been added to the SOPO and NGP has decided that they will drill the second slim well at a location to be determined. This NEPA Determination is only analyzing the additional task and subtask that have been added to the previous SOPO. Another NEPA Determination will be required to analyze the location of the second slim well once NGP determines where it would be drilled.
