reasonable and prudent conservation measures (i.e., funding contributions to the Recovery <br />Program), water depletions from the Colorado River Basin attributable to the entire mine /power <br />plant system were not likely to jeopardize the continued existence of the Colorado pikeminnow, <br />humpback chub, bonytail, or razorback sucker, and that water depletions are not likely to destroy <br />or adversely modify designated critical habitat. <br />The Recovery Implementation Program for Endangered Fish Species in the Upper Colorado <br />River Basin serves as the reasonable and prudent alternative to avoid jeopardy and provide <br />recovery to the endangered fishes impacted by depletions from the Colorado River Basin. As a <br />means of avoiding the likelihood of jeopardy to the endangered fishes and avoiding destruction <br />or adverse modification of their critical habitat, the project has provided a one -time contribution <br />to the Recovery Program in the amount equal to the average annual amount of water removed <br />from the White River (Colorado and Utah). The operator's current contribution to the Recovery <br />Program extends to an average annual depletion rate of 512 acre -feet per year (Biological <br />Opinion ES- 6- RO -95 -F- 001 - GJ286; 12/01/1999), which in recent practice (2009 -2010) has <br />amounted to about 360 acre -feet. <br />The Proposed Action would involve extending the current operational aspects of mining, coal <br />transport, and power generation with no increased demand for water anticipated over the life of <br />the project. Water use and depletion influences on endangered fish and critical habitat <br />attributable to this operation would not be altered in response to leasing the LBA and depletions <br />would remain within BME's 512 acre -feet per year Recovery Program allowance. Since the <br />estimated depletion would result in no net increase in water use or demand for that addressed <br />under previous consultations (Biological Opinion ES- 6- RO -95 -F- 001 - GJ286; 12/01/1999) the <br />FWS (FWS 2012) determined Section 7 consultation is not required for this aspect of the project. <br />Selenium and mercury are two aquatic contaminants that are associated with the burning and <br />mining of coal and have been implicated in reproductive failures and impaired growth in the <br />endangered Colorado River fishes. It has been suggested that these contaminants contribute to <br />the suite of factors that are impeding recovery of these fish throughout the Colorado River <br />system, specifically including the White River (Hamilton et al. 2005, USFWS 2011). <br />Selenium occurs naturally in the White River and is believed to be derived primarily from <br />ground and surface waters draining Mancos Shale formations. Highest selenium concentrations, <br />exceeding State - designated impairment levels, are found in tributaries near Meeker (i.e., lower <br />Flag Creek, Sulphur Creek). Selenium levels below Meeker and downstream to the Utah border <br />(8 monitoring stations) have remained relatively constant at or below 1 µg /L since 2003 and are <br />in a declining trend. Hamilton et al. (2005) considered aquatic systems within the Colorado River <br />basin with selenium levels below 1 µg /L uncontaminated. <br />Mining of these associated coal leases began in 1985 and small amounts of mine water were <br />discharged to sedimentation ponds in the ephemeral Scullion Wash drainage. Discharge was <br />discontinued in 1996. Recent (2010/2011 Deserado mine hydrology report) water quality <br />measurements of spring run -off events in channels subtending these ponds carried selenium <br />levels of 1 and 4 µg /L and are likely background soil - derived values. Similarly, most recent <br />selenium levels measured at an alluvial monitoring well along the White River at the mouth of <br />DOI- BLM -CO- 110- 2012- 0023 -EA 47 <br />
