existing powerline and old repeater access roads. The new (in this case, re-disturbed) light use <br />road segment will be constructed using sidecast construction techniques, cutting and filling as <br />needed to achieve a typical road width of about 10 - 14 feet. The pad sites will be approximately <br />80 feet wide and 130 feet long or 0.24 acres. Any salvaged topsoil will be stockpiled adjacent to <br />the pad. Drill fluids will be collected in mud pits. (Approximately, 8'D x 10'W x 40'L in size) <br />Unless otherwise requested, the borehole will be sealed and the new roads and borehole pads <br />reclaimed in accordance with the procedures further described in the PAP or in accordance with <br />the applicable regulations. <br />Threatened and Endangered Species Assessment, Cultural Resources Assessment <br />A block clearance cultural resources assessment titled "Class III Cultural Resources Inventory of <br />the Block Clearance Area Project' 'prepared August 26, 2005 by Grand River Institute has <br />previously been submitted to CDRMS. This proposed project will not effect any areas of <br />concern noted in this report. <br />A "Block Biological Clearance Project" prepared in August 2005 by Monarch and Associates <br />covers the project area. A copy of the report has previously been forwarded to the Division. <br />Borehole Completion <br />Each borehole will be drilled 13 '/o inch diameter to intersect a gate road or a cross cut. 10 % <br />inch steel casing will be cemented into the hole. The borehole is to be drilled approximately 447 <br />feet in depth to the elevation of the top of the D seam. <br />Drainage and Sediment Control <br />The drainage and sediment control system for the Elk Creek mine gob vent boreholes will be <br />consistent with the previously constructed Sanborn Creek Mine gob vent boreholes. The <br />drainage and sediment control for the Elk Creek Mine borehole sites will be managed as a small <br />area exemption with alternative sediment control provided by a combination of perimeter <br />sediment control berms/ditches and installation of straw bales, straw waddles or silt fence, etc. to <br />reduce flow velocity and trap sediment. To facilitate the control of upland drainage, if the site is <br />suitable, an upland clean water diversion will be constructed to reduce overland flow into the <br />effected area. Permit Map 2.05-M4 (4t' sheet) Drainage and Sediment Control Plan provides a <br />typical example of a drill pad lay out. Exhibit 2.05-E3, Drainage and Sediment Control Plan, <br />Section 9, Revised and New SAE's and Alternative Sediment Controls provides typical designs <br />and demonstrations for alternative sediment control and clean water ditch scenarios. Exhibit <br />2.05-E3, Drainage and Sediment Control Plan, Section 6 contains information regarding mudpit <br />hydrology demonstrations. <br />0 Page 2
