The discussion presented under Section 2.04.6(3)(a)(iii)(C) concludes there <br />is no acid or toxic forming properties in the coal or surrounding strata. <br />Therefore, no adverse impacts are expected to the hydrologic balance based <br />on acid or toxic forming materials. <br />The quality of the surface water should not be degraded. The proposed <br />location of sediment ponds B and C (see Map 20) should have a beneficial <br />effect on the sediment yields and flooding of B and C gulches. These ponds <br />will reduce the downstream flow in these gulches. The run-off from the <br />gulches has not historically been put to any beneficial use. <br />The proposed small area exemptions located along the material storage yard <br />along the old railroad bed should have a positive effect on surface water <br />quality. For the first time in many years the run-off from these areas will be <br />passed through some sediment control feature. <br />Construction of the loadout should not impact the flow of irrigation water <br />under the railroad tracks. The irrigation water has been flowing under the <br />tracks for numerous years and the track has been active with coal trains for <br />numerous years. The Terror Creek Loadout has bee active for about twenty <br />years and has not had any reported adverse effect on irrigation water or <br />water wells. The applicant will assure irrigation water is piped under its <br />tracks to eliminate any potential adverse effect. The applicant owns the <br />irrigated land south of and below its railroad tracks. <br />The quality of ground water should not be impacted unless it flows into the <br />mine. The only potential impact the mine will have on ground water is to <br />intercept it in the underground workings. Mine water discharge, if it occurred, <br />would potentially effect the concentrations of total dissolved solids in the <br />receiving stream. The mine discharge should not effect, total iron, pH, and <br />manganese in the receiving stream. <br />According to data supplied by the USGS, the annual seven day minimum <br />flow for the North Fork of the Gunnison River is 25 cfs. This low flow value <br />occurred February 17, 1978, is for the period of record from 1934 through <br />1995 and is measured upstream of the Town of Somerset, CO. <br />PR -14 2.05-116 03/14 <br />
