Goss' "Goss Sand and Gravel" <br />File No.: M-85-140, E1 Paso County <br />Dear Mr. Goss: <br />Your response to the Division's November 1, 1985 "Adequacy Letter" was <br />received by the Division on November 14, 1985. <br />Further clarifications are required prior to the November 25, 1985 scheduled <br />Board consideration of the above-captioned operation. <br />Exhibit B - Mining Plan <br />(original #) 4. Water resulting from the washing operation requires controlled <br />discharging (energy dissipator (rip-rap) at outlet, etc.) or containment and <br />resulting evaporation to minimize possible erosion. <br />Please specify how the wash-water will be handled. ~ ~ ~~~ <br />Exhibit E - Reclamation Plan <br />1.A. If the depth to the water table is 11 feet, and the lake slopes will be <br />reclaimed to 3H:1V slopes, the following computations indicate that three (3) <br />acres will require revegetation. <br />(11")+(33'~ = 33.8 Ft X 4010 Ft (perimeter) <br />11 <br />= 135,538 Ft1 : 43,560 Ft''/AC = 3.11 Acres <br />33 <br />1.8. The new map submitted illustrates the permit boundary encompasses 9.89 <br />acres. The original map stated that the sump equals 1.0 acre. The acreage of <br />affected land totals 10.89. Limited Impact operations (110) are defined as <br />those operations comprising less than ten acres and mining less than 70,000 <br />tons per year. All other operations comprise Regular Operations (112). <br />Please amend the proposed permitted acreage or remit the enclosed (112) <br />Regular Operation application from and additional information required thereby. <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel.
