vicinity of the New Horizon North mining area. Table 2.04.7-4 lists 33 wells. However one well (#92752) has been abandoned and three wells (# 236014, 236015 and 236016) are Montrose County monitoring holes. Two wells (Meehan Well # 253229 and the Glasier Well #163178) will be mined through. The Meehan Well is on land under an option to purchase that will be executed at the time of permit approval. The Glasier Well is on land that has already been leased by WFC. Both wells are producing from the Morrison Fm. (Brushy Basin Member) and will be appropriately plugged prior to being mined through. All of the remaining 27 well intakes are too deep to be affected by the pit pumping induced drawdowns in the overburden aquifer. These wells are installed in the Brushy Basin Member of the Morrison Formation. These strata are below the Dakota coal strata to be mined. Impermeable shale isolates coal strata to be mined from the Morrison wells' aquifer. One potable water well (PW -001) will be drilled to provide water for showers, sanitation, and drinking water, vehicle washing, and for fire water back up. This well will be completed in the Brushy Basin Member of Morrison Formation and will be designed to produce 5 to 10 gpm. The well will be about 200 to 220 ft. deep. Well PW -001 will be located in the SWii4, SEi/4, SWli4 of Sec. 25, T47N, R16W, at an elevation of about 5690 ft. (msl) as shown on Map 2.05.3-1 and described in Section 2.05.3 of this application. Map 2.04.7-8 (Section 2.04.7 of this application) shows the location of the existing water wells. WFC's water consultant, Bishop -Brogden Associates, Inc. (BBA), has determined the potable water needs for the NHN Mine at 0.61 acre - ft per year. Average pumping rate to fulfill this need is a modest 0.38 gpm. Potable well PW - 001 is located the following distances from existing permitted wells: Section 2.05.6(3) Page 15 Sept. 2015 (TR -11)
