Attachment E CONDITIONS OF APPROVAL FOR GEOTHERMAL UTILIZATION • A buffer of approximately 30 to 50 meters would be established around eligible and unevaluated cultural sites that lie very close to activities. When initial construction is close to the buffered areas, an archaeological monitor would be present to insure that eligible and unevaluated cultural sites are not disturbed; • The power plant, pipelines, wellheads, pump motors and motor control buildings would each be painted an appropriate color to blend with the area and minimize visibility. BLM will approve the appropriate color; • The proposed transmission line would also provide raptor protection in compliance with the standards described in the “Suggested Practices for Raptor Protection on Power Lines, The State of the Art in 2006.”; • An anti-perching device, (a cone, Kaddas Enterprises type KE1058 or equal) would be installed on the top of each transmission line pole along the entirety of the transmission line (see Figure 15 and Figure 16 of the EA); • All power poles will utilize BLM-approved raptor deterrents; • Bird flight diverters will be attached to the transmission line conductors located immediately over the open water areas of the Jersey Valley Hot Springs, and out to approximately 100 feet on each side of the hot springs. The spacing of the diverters will be approximately 15 feet between each device; • Should construction be planned within the greater sage-grouse wintering season, prior to the commencement of construction, areas proposed for disturbance will be surveyed by a qualified biologist to determine if wintering concentrations of sage-grouse exist. Any wintering concentrations of birds will be avoided by 0.6 miles; • Construction noise would be minimized through practices which avoid or minimize actions which may typically generate greater noise levels, or generate distinctive impact noise; • Ormat will obtain and comply with an Underground Injection Control (UIC) permit, as appropriate. BLM Conditions of Approval and Stipulations for Geothermal Utilization • Air Quality: An NDEP-BAPC Surface Area Disturbance Permit, documenting the areas of proposed disturbance and the best practical dust control methods to be used, will be required for because the surface disturbed would be greater than 5 acres. Best practical dust control 2
Attachment E CONDITIONS OF APPROVAL FOR GEOTHERMAL UTILIZATION methods applicable to the activities include use of water trucks to spray water on disturbed areas on a regular basis; pre-watering of areas to be disturbed; graveling of roadways, storage areas and staging areas; posting and limiting vehicle speeds to 10 to 15 miles per hour, and use of wind fences to reduce wind impacts. Implementation of the applicable best practical dust control methods, through compliance with the Surface Area Disturbance Permit, would minimize fugitive dust emissions during construction, operation and decommissioning. • Cultural Resources: Any unplanned discovery of cultural resources, human remains, items of cultural patrimony, sacred objects, or funerary items, requires that all activity in the vicinity of the find ceases, and notification be made to, Field Manager, Mt. Lewis Field Office, 50 Bastian Way, Battle Mountain, NV, 89820 (775—635—4000), by telephone, with written confirmation to follow, immediately upon such discovery. The location of the find should not be publicly disclosed and any human remains must be secured and preserved in place until a Notice to Proceed is issued by the authorized officer. • Native American Religious Concerns: Adopted environmental protection measures and mitigations proposed to address these concerns include avoidance of all eligible and unevaluated cultural resource sites and implementation ofahydrologic monitoring plan which would (see EA Sections 2.1.11, 3.9.2, and 3.3.2). Additionally, geothermal lease stipulations (see Attachment E), direct that adverse impacts to springs are not allowed. During the activities, if any cultural properties, items, or artifacts (stone tools, ile points, etc...) are encountered, it must be stressed to those involved in the proposed activities that such items are not to be collected. Cultural and Archaeological resources are protected under the Archaeological Resources Protection Act (16 U.S.C 470ii) and the Federal Land Management Policy Act (43 U.S.C. 1701). The above language is applicable to previously identified artifacts and site locations, surface artifacts possibly missed during the original survey, and any subsurface artifacts (below ground). Though the possibility of disturbing Native American gravesites within most areas is extremely low, inadvertent discovery procedures must be noted. Under the Native American Graves Protection and Repatriation Act, section (3)(d)(1), it states that the discovering individual must notify the land manager in writing of such a discovery. If the discovery occurs in connection with an authorized use, the activity, which caused the discovery, is to cease and the materials are to be protected until the land manager can respond to the situation. If any traditional cultural properties or artifacts are identified before or during development activities, a protective “buffer zone” may be acceptable, where physical avoidance is an issue, and if doing so satisfies the needs of the BLM, the proponent, and affected Tribe. The size of any “buffer zone” would be determined through coordination and communication 3
