quality permits prior to discharging water from point source(s) on the proposed mine site. Therefore, the <br />Applicant has complied with Rule 3.1.7. <br />I8. Has the Applicant demonstrated compliance with Rule 6.4.19 Exhibit S -Permanent Man-Made <br />Structures for all significant, valuable, and permanent man-made stmctures within 200 feet of the proposed <br />affected land? <br />DMG Response - The Applicant has demonstrated compliance with Rule 6.4.19 via a geotechnical <br />engineering analysis prepared by Lyman Henn, Inc. that demonstrates that any permanent man-made <br />structure within 200 feet of the affected land will no[ be damaged by activities occurring at the mining <br />operation and a geological engineering report prepared by Dc John Abel , P.E. verifying that all quarry <br />highwalls will be reclaimed to a stable configuration. <br />19. Has the Applicant demonstrated compliance with applicable groundwater performance standards, as <br />required by Rule 3.1.7? <br />DMG Response -The Applicant has committed to comply with Rule 3.1.7. The Applicant has provided a <br />hydrologic analysis prepazed by Lyman Henn, Inc. which indicates that although groundwater will <br />probably be exposed during excavation, an appreciable accumulation of groundwater is not anticipated and <br />it should not be necessary to discharge (pump) groundwater from the quarry. The proposed operation is not <br />expected to have negative off-site effects on groundwater. The Lyman Henn, Inc. groundwater study <br />concludes that adverse water quality impacts will not be experienced at nearby, offsite groundwater wells. <br />Atypical quarry blast is not likely to seriously disrnpt the general pattern of groundwater hydrology. <br />Hypothetical "plugging" of groundwater pathways along interconnected fractures is unlikely to be <br />extensive or to seriously impact transmissivity, and it is unlikely that such an effect would extend the radius <br />of influence of groundwater drawdown to a point where neazby wells would be effected. The Lyman Henn, <br />Inc. groundwater analysis also concludes that although there will be a localized effect on groundwater <br />supply ,the effect does not extend far enough to physically affect other wells in the surrounding azea. <br />Further, the Applicant has provided an adequate surface water quality monitoring program which ensures <br />protection of surface water quality, and resulting groundwater quality from i~ltrafion into the fractured <br />bedrock aquifer. <br />20. Has the Applicant provided Pre-Mining & Mining Plan Maps that accurately show the location of the <br />quarry entrance and all permanent man-made stmctures within 200 feet of the quarry entrance (affected <br />land)? <br />DMG Response -The Applicant has provided revised Maps C-1, C-2A, C-2B, & C-2C which clearly and <br />accurately show the location of the quarry entrance and the location of all permanent man-made structures <br />within 200 feet of the quarry entrance. <br />Issues Raised After the Close of the Initial Public Comment Period <br />A. The application does not adequately identify potential metal, nutrient, and sediment impacts from the <br />operation to North Cleaz Creek or offer a plan to mitigate these impacts. <br />DMG Response -See response to comments 5, 9, & 15 above. <br />B. Has the Applicant complied with Gilpin County requirements for a Special Use Permit? <br />DMG Response -See response to comment 4 above. <br />
