• the stream channel diversion. Water diverted to the stream <br />channel diversion should remain uncontaminated and be dis- <br />charged near U. S. Highway 160 in the natural drainage channel <br />which exists at that point. <br />Remaining surface water running across the disturbed <br />area, either from precipitation or snow melt, will be captured <br />in the sedimentation pond, along with Green Pond water over- <br />flow, for the purpose of settling out solids and permitting <br />natural aeration and purification. <br />Refer to Map A for the location of springs, water ditches, <br />drainage gulleys and water wells. Also refer to Exhibit "H" <br />for the ownership, depth and yields of wells. There are no <br />other water ditches or surface waters in applicant's lands. <br />14. Alternative Water Supply Information. It is estimated <br />that water will be required for mine portal construction, <br />shop buildings and other surface plant facilities, mixing <br />concrete, dust control, compaction and other minor needs. <br />Underground coal mining will require an estimated 25 gallons <br />per ton of coal mined, with additional amounts required for <br />surface dust control, wetting of coal fine dumps in the <br />summer, for personnel and small uses. Finally, water to some <br />extent will be required for reclamation and reseeding. The <br />total estimated water requirements for initial mine construc- <br />• lion work is 50,000 to 100,000 gallons, and once operations <br />are in effect, approximately 600,000 gallons per year at the <br />rate of 25 gallons per ton for 100 tons of coal per day. <br />Applicant originally estimated that the water require- <br />ments could be met by importing up to 500 gallons of water <br />per day by truck, drilling wells and the use of water encoun- <br />tered in coal seams. Fortunately, in the course of excavating <br />the area known as the Green Pond (see hiap A-1), applicant <br />encountered large quantities of water emanating from old mine <br />workings and has sought to appropriate these waters for mine <br />purposes. Applicant also has the following contractual <br />rights to use waters encountered in mining: <br />A. A Mining Lease from the State of Colorado <br />on 600 acres in Section 16, Township 35 North, <br />Range 10 West, grants to applicant the right to <br />use unappropriated underground waters on leased <br />land for mining purposes; <br />B. Mining leases held by applicant on privately <br />held coal lands grants similar rights to applicant <br />as is given by the State of Colorado; and <br />C. According to mining custom, water occur- <br />ring in or with a vein or seam of coal may be <br />considered an intrinsic part of that mineral <br />- 9 - <br />
