permitted area. Please describe any associated drainage runoff conveyance structures <br />and include sufficient information to evaluate structure sizing. <br />2. Is the applicant proposing to have a no disturbance setback between the mining <br />operations and the permit boundary? In particulaz are there setbacks between the mine <br />operations and the access roads, and if so what are the setback distances? <br />3. Please provide a copy of the approved NPDES permit (if required) for discharging the <br />water from the pit, or provide the Division sufficient process details on how water <br />quality standazds will be met to achieve the approved standazds. <br />4. Please provide a copy of the stormwater permit (if required), or provide details about <br />controlling stormwater from running offsite. Particularly provide plan details for <br />keeping sediment laden water from running off the overburden piles and onto the <br />neighboring land. <br />5. Please provide an agreement between the Applicant and the owner of the ditch for <br />allowing water to be discharged into the ditch. Please depict the location on a map <br />where mine water will be discharged. If water is discharged into a ditch that is unlined, <br />it may be prone to erosion if the discharge rates exceed the carrying capacity of the <br />ditch. The applicant should submit documentation to the Division for review as to the <br />proposed maximum discharge rate into the ditch and specifications as to how much <br />water the ditch can carry without experiencing erosion. <br />6. Please provide a copy of the Substitute Water Supply Plan or the details of the plan <br />including the quantity of produced water, where the produced water will be discharged <br />to, and details about avoiding injury to existing water rights. <br />7. In accordance with Rule 6.4.7(2)(b), the Division requests that the applicant identify <br />and characterize the aquifer to be mined in or through. The Division also requests that <br />the applicant define or predict the cone of depression expected for any areas to be <br />dewatered and dry mined during the life of the operation. The cone of depression <br />assessment should define, at a minimum, the horizontal and vertical extent of drawdown <br />expected. If during the assessment, the applicant determines that a drawdown will <br />occur offsite that may impact a current groundwater user, the applicant should explain <br />any mitigation measures to be implemented and trigger points that would put mitigation <br />measures into effect. <br />6.3.4 EXHIBIT D -Reclamation Plan <br />1. Because the use of a compacted liner still allows for seepage, it is expected that some <br />water will be in the pit. Based on the Office of the State Engineer (OSE) or Dam Safety <br />Branch criteria for allowable seepage for a lined water storage facility and estimated <br />precipitation onto the site, estimate the quantity of water that the pit would expect to <br />pond on the pit floor. Based on this estimate present in the reclamation plan an <br />adequately sized water storage structure to handle the seepage. Include at a minimum <br />the dimensions, location, vegetation efforts, anticipated water fluctuations, and drainage <br />plans for conveying the seepage to the water storage area. <br />2. Provide construction details for the compacted clay liner and the process for installation <br />and testing of the compact liner. Essentially we are looking for the plans, specification, <br />and design criteria of sufficient detail to ensure that the structure is stable and functions <br />as intended.. At a minimum provide the following <br />
