2.04.11 Fish and Wildlife Resources Information <br />effects. <br />The effect water depletion will have on the endangered fish species of the Colorado River <br />Basin is determined by estimating the annual depletion of water from the upper Colorado <br />River caused by the loadout development. The consumptive use of water associated with the <br />loadout includes water used for dust suppression and losses due to evaporation. <br />The following water depletion estimate is prepared based on the loadout handling 1.0 million <br />tons per year. <br />A. The Applicant's source of water will be a well installed near the loadout structures. <br />The Applicant can augment the flow from the well if necessary with its Mack <br />Pumping and Pipeline water right. A copy of documents that confirm the water right, <br />Case No. 02CW92, are located Volume I, Tab 1. <br />B. Water Depletion by Category: <br />Road dust suppression - It is estimated that an average of two 3,000 gallon water tank loads <br />are applied to the haul road each day for 8 months (160 days) each year. This equates to 2.9 <br />acre -feet per year. <br />Pond Evaporation (lake evaporation) is 43.5" net per year. This is calculated using 50 inches <br />of annual evaporation from a free water surface (NOAA Technical Report NWS 33) minus <br />70% of the average precipitation (9.24 ") at the Fruita weather station ( Fruita 1 W, Colorado <br />053146). <br />Surface area acres are based on full pool. <br />Conveyor Operation: <br />There are two conveyors that will run 20 hours per day 5 days per week when coal is being <br />delivered to the loadout. Each conveyor will have one spray. <br />Spray details <br />Spray Details <br />Consumption per 20 hour day <br />2 sprays <br />1.6 gpm /spray <br />3,840 gallons <br />Permit Application 2.04-38 01/12 <br />Surface Area Acres <br />Annual Evaporative Loss A -F <br />Pond 1 <br />0.37 <br />1.34 <br />Pond 2 <br />0.12 <br />0.44 <br />Pond 3 <br />0.11 <br />0.40 <br />Totals <br />0.43 <br />2.18 <br />Surface area acres are based on full pool. <br />Conveyor Operation: <br />There are two conveyors that will run 20 hours per day 5 days per week when coal is being <br />delivered to the loadout.
