<br />water elevation of the adjacent River and will be <br />constructed of 2-inch perforated plastic pipe (see Mining <br />Place Map for proposed locations). Mining will go no deeper <br />than one foot above the ground water elevation or the lore <br />water elevation of the adjacent River. These pipes should <br />also alert the mining operation to changes in the ground <br />water elevation. <br />The hydrologic changes to this river caused by this <br />operation will be minimal. The train River channel is to be <br />left where it currently is--before, during and after mining, <br />The protective berm will keep the River in its present <br />location. During high water periods, the River is expected <br />to flow where it is now and at similar rates. The current <br />surface slope of the high water channel area (the pit area} <br />will be maintained where mining is completed, only it will <br />be 2 to 3 feet deeper as shown on the enclosed cross <br />sections. The grade3 pit area will follow the present <br />surface slope of the high water channels. <br />3. MINING PLAN: <br />Letters from the U.S. Army Corpe of Engineers dated <br />April 25, 1990 and April 22, 1992 are enclosed. <br />Elevations for the low water level of the Uncompahgre <br />River are as follows: <br />UR-16 7209.1 UR-24 7200.3 <br />UR-18 7208.E UR-2E 7196.2 <br />UR-20 7205.2 UR-27 7195.9 <br />UP.-22 7X4.1 UP.-29 7192.4 <br />UR-23 7201.6 EB-5 7206.17 <br />Elevations for the Iow water elevation of the River <br />will be reestablished each year before mining begins. <br />TREES: <br />Peck Inc. has committed to leaving all trees unharme3 <br />and intact. Peck feels the trees are a valuable asset to <br />the mining operation as they screen the stockpiles and some <br />mining activity. PIo gravel will be stockpiled against tree <br />trunks. As shown. on Exhibit E-1, three stockpile areas are <br />proposed. Stockpiles 1 and 2, 35' wide by 150' long, are <br />open areas within the tree zone and cculd contain 3000 yards <br />cf material. Stockpile 3 by itself could contain 5000 <br />yards. It should be noted the maximum amount of gravel to <br />be stockpiled is 5000 yards. Actual stockpiles during <br />operaticn may be less, as only projected needs will be <br />stockpiled. All material contained in stockpile 3 vrill be <br />removed prior to the next years' river flood stage. <br />MINING AND 3:1 BANK SLOPES: <br />A survey completed by E. Schoaf and Associates in 1990 <br />established numerous elevation control points around and <br />through the per.;,it area. From these points elevations on a <br />50' grid will be established prior to mining each area. The <br />grid points will all be referenced to the low water <br />Y <br />
