There are <br />two copies of all items. <br />4.A map showing more detail of the proposed haulage road, ramp, and berms <br />planned for the Pad area is enclosed. Any elevated portion of a roadway is <br />required by MSHA to be bermed. A berm will be needed along the top of the <br />cliff, beginning near the southwest side of county road, above the adit, and <br />continuing northwestward until it turns to Follow the proposed new cut for the <br />ramp. The top of the old dump will be bermed, as previously mentioned. <br />At the top of the new cut roadway, where it is at the elevation of the Pad, it <br />will flatten for a short distance. A high spot, or a small water bar, will be <br />maintained at the start of the cut in order to prevent stormwater falling on the <br />Pad from running down the ramp. The planned berm on the west side of the <br />Pad area will contain this water. The small amount of stormwater that might <br />run down the sloping (fill) section of the haulage road, between the Pad and <br />the county road, will also be contained by this berm. <br />Two other maps are included showing more detail of the catchment azeas to <br />be constructed at either end of the waste rock/ore stockpile area These maps <br />show the location and size of the proposed catchment areas. The berms will <br />be built to a height equal or greater than the elevation of the county road. The <br />area on the waste dump side of each berm will be scooped-out to a depth, for <br />most of the bottom, that is 30 inches below the elevation of the county road. <br />Cotter Corporation -West Slope Operations <br />P.O.
