Water Riohts and Reol <br />6(3)(a)(ii <br />Information regarding surface water use, ground water use, and alternative <br />water supply information can be found in Volume 3, Tab 3 (7-63A to 7-63B) of <br />the permit application. A description of water rights is provided in Volume <br />3, Tab 3 (7-64 to 7-68) with legal court decrees included in Volume 5, <br />Appendix 7-8. <br />The water rights obtained for the mine are a ditch (Nuc1a Mine Ditch), a <br />ground water well, GW-N5 (Nucla Mine Shop No. 92752), NPDES Pond No. 1 (Nucla <br />Mine Reservoir No. 1), and NPDES Pond No. 6 (Nucla Mine Reservoir No: 2). The <br />water well was plugged and abandoned according to proper procedures in 1986 as <br />part of the mine activities in Mine Area No: 4. <br />The ditch and two ponds are decreed for sediment settling (storage right) as <br />well as for dust control and wildlife use. <br />Peabody has identified all adjudicated water wells within one mile of the <br />permit area. Due to the hydrologic characteristics of the area, no adverse <br />impacts to any water well are anticipated. However, if contamination, <br />dimunition or interruption of a ground water source were to occur as a <br />consequence of the mining operation, Peabody has committed to replacing that <br />water supply with one of comparable quality and yield. <br />There are no additional uses of water at the mine that would require a water <br />right, storage right, or permit. Furthermore, the applicant's statement of <br />probable hydrologic consequences does not predict any impact that is or could <br />occur so as to injure adjacent water users. <br />The operation is in compliance with the requirements of this section. <br />IX. Assessment of Probable Hydrologic Consequences of Mining and Cumulative <br />v~nnir mnar}e _ i, nc ~I~iT~an~-~~7~f r <br />A. Introduction <br />This cumulative hydrologic impact statement (CRIB) is an assessment of the <br />probable cumulative impacts of all anticipated coal mining upon the hydrology <br />of the area. Cumulative impact refers to the hydrologic impacts that may <br />result from the accumulation of flows from all coal mining operations to <br />common stream channels or aquifers within the cumulative impact area. This <br />area includes the permit area, adjacent areas and all other additional areas <br />where, as a result of hydraulic continuity, material damage to the hydrologic <br />systems might occur. <br />-15- <br />
