The plan would also describe measures and actions that would be taken to minimize, as much as possible, adverse effects of a hazardous materials spill to the environment. The plan would include provisions for portable baffles or booms to be used on land and in the reservoir to contain and impede the spread of a spill. Activities to clean a spill and repair a pipeline could disturb eagles in the area of the reservoir. Appropriate measures would be taken to minimize this disturbance. A petroleum product monitoring element would be incorporated into the water quality monitoring program for potential adverse bioaccumulation of trace elements in bald eagle food items in Ridges Basin Reservoir (i.e., Conservation Measure 6 of the Animas-La Plata Project FSEIS). Periodic surface and/or aerial inspections would be conducted along the pipeline corridor and the Ridges Basin Reservoir shoreline to provide early detection of small leaks that go undetected by small pressure loss in the pipeline. 2) Either alternative may require an inventory for the yellow-billed cuckoo or its habitat. It is unlikely that the yellow-billed cuckoo habitat occurs or would occur in the project area, and the proposed pipeline construction or operation would not affect this species. 4.3 Conclusion Reclamation concludes that the Ridge Basin Dam and Reservoir pre-construction facilities relocations project is not likely to adversely affect the Colorado pikeminnow and razorback sucker, or destroy or adversely modify critical habitat. Reclamation further concludes that the project may affect, but is not likely to adversely affect the bald eagle. This conclusion is based on the description of the proposed action contained in this Biological Assessment and the associated Environmental Assessment, with full implementation of stated conservation measures.
