Diversions from the Gunnison River for Project purposes do not reduce flows below that necessary to operate a fish passage structure at the Hartland Diversion Dam, should such a structure ever be built. . FWS is to be included in annual meetings (in addition to Aspinall operation meetings) to discuss Gunnison River operations and potential problems that may develop. . Sponsors are to develop a southwestern willow flycatcher monitoring plan for the project area. This will be done prior to construction. . Monitoring of riparian habitats include specific monitoring of southwestern willow flycatcher nest sites and nesting habitat. . Sponsors are to develop a contingency plan, prior to construction, to replace southwestern willow flycatcher nesting habitat if project operations adversely affect such habitat. . If Gunnison icing occurs below Crystal Dam and becomes a problem for eagles, take measures such as flow augmentation to ameliorate adverse effects. . Survey and marking of threatened/endangered plants in the penstock construction right-of-way (ROW); reduced ROW widths when appropriate, and routing of access roads to avoid impact. . Limitation of waste storage in the vicinity of endangered plants. . Acquisition and transfer to BLM of off-site plant habitat Endangered species and conservation commitments are described in more detail in Chapter 3, To reduce the possibility of raptorlO electrocution, a raptor-proof design would be used for transmission lines. To provide deer with a means of escape, two ramps would be constructed in the concrete-lined portion of the AB Lateral, and a cable barrier just downstream would direct deer toward the escape, 2.4.8 Pollution Control and Aesthetics Construction specifications would include provisions to limit noise and air pollution. The powerhouse, tailrace, and associated features would be designed and landscaped to reduce visual impacts. Other provisions include the following: a containment plan for oil storage at the powerhouse; water quality permits to be followed during construction and operation; and lining of the enlarged AB Lateral to reduce seepage and resulting salt loading to the Uncompahgre River. There may be temporary service disruptions due to utility line relocations associated with penstock construction. These will be minimized to the extent possible and coordinated with service providers and local government. 10 A raptor is a bird of prey such as a hawk, falcon or eagle, AS Lateral Hydropower Project July 2000
