-t o- <br />be high in total dissolved solids. Over a long period of time, the quality of <br />the spoils water will improve as the leaching process is completed. The <br />length of time required to leach degrading constituents from spoils is <br />presently being studied by the scientific community. It is clear, however, <br />that the time element is dependent upon the amount of water available, and the <br />rate at which it passes a given point in the backfilled pit. It is thought <br />that this leaching process may take centuries. <br />The elimination of the Sudduth Coal spring in Section 15, T9N, R78W, will not <br />adversely affect the local hydrologic regime. This spring discharges water <br />which is poorer in quality than it's receiving stream, Sudduth Draw. It is <br />also speculated by the permittee that the amount of water discharged from this <br />spring - approximately one gallon per minute, is an insignificant proportion <br />of the total Sudduth Draw flow. <br />Ground Water - Tipple Area <br />The Kerr Coal Company Tipple, or loadout area, is located adjacent to the <br />Illinois River south of Walden, Colorado. <br />The loadout is built upon manmade fill which has been placed on the Illinois <br />River alluvium. <br />The alluvium in this area is saturated, with the water level higher in <br />elevation than land surface most of the year. It is thought that this is a <br />discharge area. <br />As the loadout is built above the alluvium and water surfaces, there will be <br />no dewatering of the facilities area necessary at this site. <br />Surface drainage systems have been built which prevent water from standing on <br />the site, except for in the pond. Some water from the pond will infiltrate to <br />the underlying alluvium during the spring and after precipitation events. Due <br />to the saturated nature of the alluvium, any increases in total dissolved <br />solids will be immediately diluted. <br />The operation is in compliance with the requirements of this section. <br />Cummulative Hydrologic Impact Statement Rule 2.07.6(2)(c) <br />The cummulative hydrologic impacts of mining to the ground and surface water <br />systems has been evaluated by the Division on local and regional scales. <br />The temporary effects to the local hydrologic regime will be significant <br />during the life-of-mine. <br />The temporary effects to the Regional Hydrologic Regime will be insignificant. <br />Both temporary and long term effects to the local and regional hydrologic <br />regimes after mining and reclamation activities have been completed are <br />negligible. <br />
