6.4.7 EXHIBIT G -Water Information <br />20. In accordance with Rule 6.4.7, please provide a statement of whether the operation is or is not <br />expected to directly affect surface or groundwater systems. (The Division anticipates that the <br />groundwater system in the affected land and surrounding area will be directly affected since at <br />least 125 acres will be de-watered to an average depth of at least 25 feet and dry mined). Please <br />respond. <br />21. In accordance with Rule 6.4.7(2)(b), please identify and chazacterize the known aquifer to be <br />de-watered and dry mined. Please include the average or the expected range of groundwater <br />depth below the ground surface, assuming natural and non-disturbed conditions. Please respond. <br />22. In accordance with Rule 6.4.7(2)(c), please submit a brief statement or plan showing how <br />water from de-watering operations or runoff from disturbed areas, piled material and operating <br />surfaces will be managed to protect against pollution of either surface or groundwater (and, <br />where applicable, control pollution in a manner that is consistent with water quality dischazge <br />permits), both during and after the operation. <br />23. In accordance with Rule 6.4.7(3), please provide an estimate of the project water <br />requirements including flow rates and annual volumes for the development, mining, and <br />reclamation phases of the project. <br />24. In accordance with Rule 6.4.7(4), please indicate the projected amount from each of the <br />sources of water to supply the project water requirements for the mining operation and <br />reclamation. <br />25. Please clarify whether the Greeley #3 Ditch is an active ditch, ie: flowing water during part or <br />all of the year; and whether the ditch will or will not be adversely affected by VCI's de-watering <br />and dry mining activities. <br />26. The appkcant indicates that they have obtained a Substitute Supply Plan (SSP) from the <br />Office of the State Engineer in July, 2003 to cover both existing and planned exposed ground <br />water. However, attached is a copy of review comments from the Office of the State Engineer <br />(OSE) which indicates that the existing substitute water supply plan for the Durham Sand and <br />Gravel Pit expired on October 31, 2003 and that VCI will need to obtain a either a gravel pit or <br />other type of well permit for the proposed activities. Further, included in Exhibit G -Water <br />Information is a copy of July 1Q 2003 correspondence from William H. Fronczak of OSE to <br />Cheryl Signs that indicates the following: a) the existing SSP is conditionally approved until <br />October 31, 2003 and that permanent approval of the plan is necessary, b) a well permit must <br />also be obtained in conjunction with the approved SSP, c) VCI application for a SSP assumes the <br />condition of a lined pond, rather than a groundwater fed lake. Please respond. <br />27. The applicant has petitioned the Division to agree as part of the approval of this Amendment <br />application (AM-1) that any subsequent and necessary revisions to Permit M-78-056 pertaining <br />to the Floodway or Floodplain be allowed as a separate technical revision. The Division requests <br />
