MMRR Quarry, M-2004-067 Response to June 30 Adequacy Review (as amended) August 19, 2005 Page 6 an operator to minimize disturbances to the quantity and quality of both surface and groundwater. Stormwater management and surface runoff are discussed extensively in reference to adequacy comments 11 through 20 (see below), leaving groundwater impacts to be discussed in reference to the present adequacy comment. Groundwater hydrology and the potential impacts of this application on groundwater quality and quantity are discussed in the attached report submitted by Lyman Henn, Consulting Engineers. Please refer to that report for detailed analysis relevant to Rule 3.1.6(1)(b). As noted in the Lyman Henn report, topographic conditions, distance to wells, and other hydrologic considerations form the basis for the proposed approach to minimizing effects to the prevailing hydrologic balance. M-2004-067 will also comply with all applicable federal and state laws pertaining to water quality and water rights. The proposed mining and reclamation plans will maintain positive drainage to project-related stormwater facilities at all times. 8. The applicant has specified that realignment of the main access road will generate an additional 400,000 cubic yards of cut and due to the site layout, this volume of material must be primarily hauled off-site prior to the opening of the access road, processing pad, waste rock pile, and other options for use on-site. Please describe the nature of the material to be generated, the location(s) where this material will be taken, and its intended use. The proposed additional cut material referenced in this question was the rock mass directly between the ravine area (e.g., the location of processing equipment) and the proposed access point opposite the driveway of the Clear Creek Convenience Store. This access point has been eliminated, which in turn eliminates the bulk of additional cut material and the plan to dispose of such material off-site. To the extent that rock blasted during site development is marketable, such construction materials would have an end use identical to rock later produced during production blasting (e.g., specification construction aggregates). It is, however, extremely unlikely that marketable material will be generated prior to the establishment of a site for a primary crusher or prior to the development of a pad site using materials generated during the site development phase. The current application reverts to the general plans for site development in place prior to the March 23, 2005 submittal, and, to reiterate, the 400,000 cubic yards in question will remain in place on the site.
