• the 8240 contour (see Mine Plan, Exhibit ). Three monitoring wells, LA, 1B and 1C were subsequently installed between the 8210 and 8220 contours below any proposed mining activities (see Exhibit C-2). Well lA is located in the coal, 1B is in the overburden and 1C is located below the coal. These wells should provide adequate groundwater information related to the mining activities. Lithology logs and descriptions of well completions are found at the end of this Appendix. The locations of all groundwater monitoring wells are shown on Exhibit C-2 at the end of this Appendix. Surface Water Information The Willard Owens report at the end of this Appendix contains surface water information including the name of the watershed which will receive water discharges; the location of all surface water bodies such as streams, lakes, ponds, and springs; the lccation of any water discharge into any surface body of water; and descriptions of surface drainage systems. • Bolton Draw drains an area of approximately 10.6 square miles including the Pit 1 area (see Plate 4, Willard Owens report). The 90 acre lease area drains into a small arm extending southwestward from the main channel of Bolton Draw. No gauging stations existed on the ephermal stream draining into Bolton Draw prior to the original permit application; however, diversion records of a ditch right located in the NW4 of the NE; of Section 11, T8N, R78W, give some indication of historic flows at this midpoint in the drainage near the proposed mine. Diversion records for this right are presented in Table II, Willard Owens Report. Since no gauging equipment was in place on the Draw, these values for flow are estimates. However, they probably represent with reasonable accuracy, especially in later years, the spring flow in the Draw. Flows in the Draw probably decline thrcuah the summer and eventually disappear in the fall and winter. • -51-
