NEPA Proposed Action Cayley Geothermal, Inc. (Cayley) is propos
Cayley Geothermal, Inc. (Cayley) is proposing to conduct the Reese River Valley Geothermal Exploration Project (Project), a geothermal resources exploration program of temperature gradient hole (TGH) and slim well drilling and testing on public lands leased for geothermal resource development in Lander County, Nevada (Figure 1). The area to be explored (Project area) consists of portions of federal geothermal leases NVN-78687, NVN-77247, NVN-78688, and NVN-76676. The Project area (see Figure 2) covers the entirety of Sections 32 and 33, and the W½ of Section 34, and SW¼ of the SE¼ of Section 34, Township 24 North, Range 43 East (T24N, R43E), Mount Diablo Baseline and Meridian (MDB&M); and the W½ of the W½ of Section 3, the entirety of Sections 4 and 5, the E½ of Section 6, and the N½ of the N½ of Sections 8 and 9, T23N, R43E MDB&M. The Project (Proposed Action) includes (see Figure 3): *Drilling up to eight temperature gradient holes (including the improvement, reconstruction or construction of access roads, as necessary), each to a depth of either 300 or 1,000 feet and measuring the temperature profile in each TGH; and *Constructing drill pads on up to three of seven sites (including the improvement, reconstruction or construction of access roads, as necessary), drilling and completing a small-diameter (slim) well to a depth of about 4,000 to 5,000 feet from each of the three constructed drill pads, and flow-testing each completed slim well to obtain samples of the geothermal fluid and production information from the geothermal reservoir. The total estimated area of new surface disturbance required for construction of the drilling pads and access roads would be a maximum of approximately 9.68 acres (see Figure 3)

BMPs Road Slope and Spoil Disposal Area Stabilization Identify soil environmental site factors and their variance along the roadway. Determine the proper seed/fertilizer mixture to stabilize roadway slopes and waste spoil areas. Mechanical stabilization should be accomplished in highly erodible soils using geotechnical materials, jute netting, punched straw or other proven technique. In areas of highly erodible soil, windrow clearing debris at the base of the fill slopes to mitigate erosion. Road Slope Stabilization For cut slopes, allow them to be left as steep as possible to minimize the surface area subject to erosion. Do not lay the slopes back. Control of Road Drainage For roads within highly erodible areas, use insloped roads only in cases where maintenance can be performed on a regular basis. All other roads should be outsloped. For highly erodible soils, inslope and ditch fill sections with culverts in order to prevent water from flowing down the face of fills. Berms may be used to direct water to overside drains, if available. Culvert headwalls should be constructed for perennial or intermittent stream crossings in highly erodible soil areas using riprap, soil cement, concrete, in order to prevent erosion. Energy dissipators should be used in areas of water concentration, where significant erosion will result Construction of Stable Embankments (Fills) and Culvert Backfill In highly erodible soil areas, the larger and more critical fills should be compacted to 95% of AASHTO T-99 specification. Fillslopes should be constructed at 1½ to 1. For fills compacted through layer placement along, fillslopes should be constructed at 1¾ to 1. No fills will be constructed on side slopes exceeding 55%. For areas designed to have compacted fills and having slopes exceeding 40%, terrace the natural slope to key in the fill. Care should be taken to compact the outer edge of the fill in highly erodible soil areas using a sheeps-foot type roller or other approved techniques. Maintenance of Roads In highly erodible soil areas, special attention should be paid to maintaining road drainages, including surface drainage configuration, culverts and overside drains for roads having all levels of maintenance. Cut slopes should not be undercut and drainages should be kept open, clean and functioning. Road Surface Treatment to Prevent Loss of Materials For road construction in areas having highly erodible soils, full-width stabilization, including the ditch, should be performed using aggregate, asphalt concrete, penetration oil treatment or other approved methods that will achieve long term stabilization of the road bed. Stabilization methods should be designed to exceed normal use so erosion control devices remain effective well past the intended use. Stabilization should be considered for road segments adjacent to or crossing sensitive streams, grades exceeding 6% and for areas having sideslopes in excess of 30%.

, Each area proposed for any new surface dis
Each area proposed for any new surface disturbance, including an appropriate buffer, would be surveyed by a professional archeologist acceptable to the BLM, and the results of this survey reported to the BLM with the request to commence surface disturbance. Drill pads would be constructed in such a way so as to ensure that recorded archaeological site materials are inventoried, documented and reported to the BLM, and a determination of their eligibility for the National Register of Historic Places and appropriate mitigation, if any be completed by the BLM prior to disturbance to the site. To ensure that identified cultural resource sites adjacent to areas of disturbance are not disturbed, the limits of surface disturbing activities, including an adequate buffer zone, would be clearly marked and flagged prior to the start of all grading or other surfacedisturbing activities. The flagging would be set with the assistance of a professional archaeologist, and the construction/grading contractor and each of the workers would be trained to understand the flagging and its importance. BLM may determine that an on-site monitor is necessary. 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, and the BLM would be notified. Grading or other surface-disturbing activities would not recommence at the location of the discovery until the identified cultural resources(s) have been assessed, any necessary mitigation actions taken, and the expressed approval of the BLM granted.
