quality of water in groundwater systems both during and after the mining operation will <br />be minimized? (Section 34-32.5-116(4)(h); Rule 3.1.6). Specific concerns are as <br />follows: <br />• Exposure of the groundwater table; <br />• Compliance with applicable Colorado water laws and regulations governing <br />injury to existing water rights; <br />• Potential impacts to water quality including magnesium chloride used on the <br />roads. <br />B. Has the Applicant indicated the projected amount from each source of water to <br />supply the project water requirements for the mining operation and reclamation plan? <br />(Rule 6.4.7(4)) <br />C. Have all affected lands been identified? (Rule 6.4.1) <br />Issue 7(A), Minimization of Disturbances to Hydrologic Balance. Section 34-32.5- <br />116(4)(h) and Rule 3.1.6 requires an applicant to minimize disturbances to the hydrologic <br />balance of the affected land and of the surrounding area and to the quantity or quality of <br />surface and groundwater systems during mining and reclamation. As described in the <br />Division's "Rationale for Recommendation of Approval" ("Rationale"), the Applicant <br />will minimize impacts to existing hydrology by mining no deeper than 40 feet below the <br />existing surface where depth to water at the site varies from approximately 55 to 65 feet <br />below the surface. The Applicant will also mine at a grade upward from the current edge <br />of mining so that the mining floor at the conclusion of mining will be approximately 5.5 <br />feet higher than at the beginning. The Applicant will also monitor groundwater levels <br />during mining to ensure that the mine floor is at least two feet above the groundwater <br />Thompson Properties <br />M-1983-102 <br />
