<br />Exhibit D; Mining Plan <br />Response Pgh #/; Slope Gradient During Mining -The mined face will be controlled <br />by MSHA accepted practices. Shear faces will exist in the active mine. Non-active fines will be <br />knocked down seasonally to asemi-stable condition Less than vertical, for temporary keeping and <br />hazard reduction. <br />Re.sporrre Pgh #2; Runoff Control - A commitment to a "No-Discharge" design is <br />made by the operator. Temporary interior sediment control berms will be constructed as <br />necessary to maintain this condition during mining, Ditches depicted by "Detail A" will be <br />constructed on a level contour, in an attempt to minimize concentration of flows. The mine is to <br />be maintained as a "No-Discharge" design with the exception of the access road. The' final <br />reclamation plan and runoff controls will be reviewed and approved by a Colorado reeistered <br />Professional Engineer prior to beginning Phase II mining. <br />Response Pgh #3; Onsite processing to include Crushing, Screening, Asphalt and <br />Asphalt related product production and Concrete batching and Concrete related product <br />production. All onsite processing is considered intermittent activity specific job related with a <br />continuous onsite duration of less than 6molevent. Asphalt batching is intended for this; site. The <br />curtent plan is for utilization of portable equipment on an intermittent basis. All equipment is to <br />maintain proper permit requirements with applicable regulations while present onsite, including <br />but not limited to APEN's and CDOT regulations. All liquids stored onsite will be bermed to <br />control potential spillage. In addition fuel products stored onsite (excluding Fuel Trucks) for <br />longer than 30 days will be stored inside a synthetic lined container. <br />Response P.H.#4; Topsoil Stabilization - Topsoi{ stockpiles that will remain for more <br />than 2 years will be seeded with the same reclamation mixture presented in this permit f or final <br />reclamation seeding. <br />Exhibit E; Reclamation Plan <br />Response Pgh #!; Fertilizer -Will not be used for initial reclamation attempts. <br />Response Pgh #2; Topsoil Depth -This depth is revised to 12" - 18" of topsoil will be <br />used throughout the site. Excess topsoil at mine closure will be distributed on the pit floor. <br />Response Pgh #3; Cobble Discharge Apron, Runoff Control Ditches and Fences -See <br />Exhibit F below. <br />Exhibit F; Reclamation Plan Map <br />Response Pgh # I; Visual Berm -Map is revised for Phase I, Phase II and Reclamation <br />to include a visual berm. <br />Response Pgh #2; Acreage -Stated acreage's have been revised. <br />Response Pgh #3,' Runoff Control Ditches and Discharge Apron's -These are to be <br />incised into the reclaimed 3:1 slopes to control long slope erosion. It is the intent of the design to <br />not concentrate flows but to manage the dispersion of incident precipitation. In managing <br />dispersion of precipitation the discharge aprons will be constructed on the end runs of each runoff <br />control ditch to control out fall from the ditch. Each runoff control ditch will be constructed <br />along a level contour to minimize runoff and flow concentration. <br />Received <br />NOV 2 8 1992 <br />Durarxp Field ONfCe <br />pivisipn of INinerale 3 Geology <br />
