Biological Assessment <br /> Federal Coal Lease Modification(COC-62920)and Federal Mine Permit(CO-0106A)Revision and Renewal <br /> to specific populations (that do not occur at a range-wide level)including the ongoing negative <br /> effects of past mining operations on water quality; the impacts of grazing, logging, and road/trail <br /> construction/use on riparian habitat and streambanks, causing increased erosion, sediment <br /> deposition, water temperatures, and turbidity; and the co-occurrence of non-native salmonids <br /> with greenback populations. <br /> 5.1.3 Colorado Pikeminnow and Razorback Sucker <br /> The Colorado pikeminnow and razorback sucker are included in this BA due to OSMRE's <br /> obligation to consult with the USFWS on all discretionary OSMRE permitting actions within <br /> OSMRE's authority that have the potential to deposit mercury in the San Juan River. In this case, <br /> the trigger for USFWS consultation is the release of less than 0.25 pound per year of mercury <br /> from combustion of King II coal by the DSNGRR along the Animas River in Colorado, a <br /> tributary to the San Juan River. Descriptions of each species and their critical habitats along the <br /> San Juan River are detailed in the FCPP/NMEP BO (USFWS 2015) and incorporated in this BA <br /> by reference. <br /> July 2017 <br /> 26 <br />
