observed in the permit area. However, the potential exists for the following rare and endangered species to be found <br />within the Permit Area; golden and bald eagles, greater sandhill crane, peregrine falcon, and black- footed ferret. In <br />addition, the potential exists for the Colorado squawfish to inhabit sections of the Yampa and Williams Fork rivers. <br />However, no Colorado squawfish were observed during the quarterly fish and benthic organism survey that was <br />conducted in selected sections of the Williams Fork River for a period of two and one -half years. <br />MCM has made a commitment to report all sightings of rare and endangered species to the CDRMS. The report will <br />include species identification, date, and location. The following sightings of rare and endangered species have been <br />noted by MCM personnel: greater sandhill crane, golden eagle, and immature golden or bald eagles. All sightings <br />have been reported to the CDRMS and OSMRE. <br />To further protect raptors, MCM employs a raptor -proof design on all newly constructed power poles. A typical <br />raptor -proof design is presented in Figure 58, Typical Raptor -Proof Powerpole Diagram. <br />RAG Empire (MCM's predecessor) conducted a fish and benthic organism survey in the Williams Fork River near the <br />coal storage silo for 2.5 years. As a permit stipulation, the survey was to be conducted for five years. The stipulation <br />was, however, removed in August 1982, after RAG Empire provided a statistical demonstration that the mining <br />operation was not impacting the biota of the Williams Fork River. <br />PROTECTION OF HYDROLOGIC BALANCE <br />Ponds, Ditches and Diversions. MCM has a drainage and sediment control plan in place, which controls all water, <br />which moves into, through, and out of the Permit Area. The drainage and sediment control plan is shown graphically <br />on the Drainage and Sediment Control Map (Map 26). The drainage and sediment control system consists of <br />sediment ponds, ditches, culverts, and a bridge over the Williams Fork River. In addition to these structures, the <br />Drainage and Sediment Control Map (Map 26) shows the locations of the fresh -water systems and the mine -water <br />handling system and associated ponds. <br />The Drainage and Sediment Control Map (Map 26) also shows several small disturbed areas that are not included <br />within the sediment control system. MCM has requested Small Area Exemption (SAE) variances in accordance with <br />Rule 4.05.2 (3) for these areas. Details regarding these SAE's are provided in Exhibit 18. MCM will maintain <br />containment berms, vegetative cover, and grass filters, as required by the designs shown in Exhibit 18. <br />Design methodologies and calculations for all drainage and sediment control structures have been included in Exhibit <br />18, Drainage and Sediment Control Plan. All engineering designs were performed by a qualified, Registered <br />Professional Engineer. <br />Hydrologic Collection, Recording, and Reporting Plan <br />The plan for collecting, recording, and reporting of hydrologic data is presented in Exhibit 29, Water Quality <br />Monitoring Manual. The Annual Hydrology Report will be submitted by March 30, for the previous calendar year. <br />Data submitted will include piezometric maps, statements concerning observed inflows from the floor in the active <br />sections during the preceding year, plots of water levels, and appropriate water quality trends. <br />PROBABLE HYDROLOGIC CONSEOUENCES <br />Mine Inflows <br />Past and Present Inflows. A plot of the quarterly discharge for the No. 5 Mine discharge point in presented in Figure <br />21, in Section 2.04.7, Hydrology Information, for the period 1982 through 1992, along with the 7 -North Angle <br />discharge starting in 1989. These discharge points include inflows to both the No. 5 and No. 6 mines, which are <br />pumped to the surface. <br />TR14 -36 2.05 -36 Revised 03/20/14 <br />
