<br /> <br />The applicant should submit the potentiometric <br />surface of any known aquifers in the area, along <br />~ with known uses of water in the aquifer and water <br />able (including flow rates and water rights). If <br />J any groundwater rights are adjudicated at a later <br />time in the three mile radius of the permit area, <br />the applicant should indicate this in an annual <br />report. <br />If the McClane Canyon Mine will affect the ground- <br />water quantity and/or quality, identify alternative <br />sources of water supply that could be developed to <br />replace the existing sources. This information <br />Q should include the source and its location, quan- <br />tity, quality, distribution scheme and compatibil- <br />ity with postmining land use, maintenance, and <br />Colorado Water Law. <br />Provide additional information on the known and <br />!~ potential quality of water in the coal and adja- y/~ <br />~ [ cent stratigraphic zones as related to the pot- <br />tential for environmental contamination by any <br />\ mine-water discharge in compliance with 783.15. <br />Provide the depth of each annlicable well. <br />~~ <br />-Provide information on thickness of aquifers and <br />;"~ water levels in alluvium ~nd relate to possibil- <br />~ ities of using deeper monitoring wells to minimize <br />~" "dry holes" when.water tab"le declines, in complia e <br />'th 783.15. <br />n The mine plan discusses the dry conditions that <br />~J-l will be experienced during proposed mining oper- <br />ations, but does not adequately cover the possi- <br />~. bilities of encountering saturated conditions if <br />~ mining is extended throughout the "permit area" <br />V shown on Figure 2.1-1. Will the mining extend <br />`~ into saturated groundwater zones? Describe in <br />more detail the extent of proposed mining (e.g., <br />'n '' Fig. 2.1-1) with adequate wording, symbols, or <br />~ legend. Should mining extend into saturated zones, <br />inventory of wells in the adjacent areas would be <br />-`' necessary and impacts of mining on these wells <br />would need to be evaluated. Provide information <br />on known and potential groundwater recharge, and <br />~ discharge occurrences in the deeper down-dip coal <br />zones within the permit area. Include information <br />of possibilities of recharge from upper reaches of <br />E. Salt Creek (north of the permit area), from <br />water occurrences at drill holes 7-35-1 and 7-3-4 <br />(north of the permit area), and along the strata <br />or through faults and fractures into the deeper <br />coal zones. <br />4 <br />
