Construction Material Regular 112 Operation Reclamation Exhibits <br /> Raindance Reservoir#2 —VIMA Partners, LLC <br /> The capacity is designed at 1,500 acre feet with approximately 475 acre feet of <br /> annual consumption divided between Raindance River Reservoir and Reservoir Number <br /> 2. Water use from each reservoir will vary from year to year based on water availability <br /> and operation. Additionally, assuming 11 acres of planting and seeding for the disturbed <br /> areas and about 1.5 vertical feet of water over that area needed for watering purposes for <br /> the reclamation process, an additional 16.5 acre-ft will be needed. Temporary sprinklers <br /> may be used to establish seeding during the reclamation process. The water will be <br /> supplied from the existing non-potable water system. <br /> (4) The Operator/Applicant shall indicate the projected amount from each of the sources of <br /> water to supply the project water requirements for the mining operation and reclamation. <br /> Water trucks will be used for dust mitigation throughout the construction of the <br /> reservoir. Assuming one full time water truck during construction, about 1300 gallons of <br /> water will be used per day. Construction water will be purchased from the Town of <br /> Windsor. <br /> (5) The Operator/Applicant shall affirmatively state that the Operator/Applicant has acquired <br /> (or has applied for) a National Pollutant Discharge Elimination System (NPDES) permit from the <br /> Water Quality Control Division at the Colorado Department of Health and Environment, if <br /> necessary. <br /> Discharge Permit—COR403818 recently revised and updated with the state for <br /> this project. <br /> Water Information — <br /> There are no known aquifers in the area, however, if groundwater is encountered <br /> temporarily, proper dewatering procedures and practices as defined in the Mile High <br /> Flood District Criteria Manual will be utilized. If any rain events occur and cause standing <br /> water within the operation, the water will be pumped out. Any discharge will occur at the <br /> current detention pond outlet point. <br /> The reservoir will use 1500 acre-ft of water to fill. Additionally, assuming 11 acres <br /> of planting and seeding for the disturbed areas and about 1.5 vertical feet of water over <br /> that area needed for watering purposes for the reclamation process, an additional 16.5 <br /> acre-ft will be needed. Temporary sprinklers may be used to establish seeding during the <br /> reclamation process. The water will be supplied from the existing non-potable water <br /> system. <br /> Water trucks will be used for dust mitigation throughout the construction of the <br /> reservoir. Assuming one full time water truck during construction, about 1300 gallons of <br /> water will be used per day. <br /> TST.INC.CONSULTING ENGINEERS <br />
