2.04.7 Hydrology Description <br />increase until the mine workings are developed to the north where the coal <br />seam is saturated. Mining to the north may increase the mine inflows to <br />the 30 gpm range experienced during 2005. <br />(4) A description of the maps prepared according to the standards of rule 2.10 <br />follows: <br />(4)(a) The locations of water supply intakes, ditches, reservoirs, and wells within <br />a one mile minimum radius of the affected area are shown on Figure 1.1- <br />3a Interests in Surface Property and Water Rights. The only structure is <br />the H.F. McClain ditch and the owner is #11 Enterprises (see Appendix A). <br />Three separate filings have been made on this diversion ditch and are: <br />ID <br />STREAM <br />AMOUNT <br />ADJ.

Only East Salt Creek has the potential <br />to receive run-off from the area disturbed by the underground mine. East <br />Salt Creek will receive discharges, if any, from the underground mine and <br />the sediment pond. The mine will discharge into McClane Creek which is <br />tributary to East Salt Creek. Figure 2.2-2 shows the location McClane <br />Creek and the sediment pond. <br />(4)(b) The location of monitoring stations used to gather data for water quality <br />and quantity is shown on Figure 4.2-2, Water Sampling Locations . The <br />elevation of the stations is depicted on Figure 4.2-2. <br />PR -02 2.04-30 03/13 <br />
