The average grade of the Portal Access Road will be 10 percent or less. All drainage <br />from the Portal Access Road will report to the sediment pond. The out slope of the road <br />will be bermed or have a guardrail for vehicle protection and erosion control. If a berm is <br />used for vehicle protection it will meet Mine Safety and Health Administration height <br />requirements. <br />• <br />Water Tank Access Road <br />Presently there are two tanks scheduled for the King II Mine. One tank will be used for <br />the storage of potable water. The second tank will be used for the storage of water that <br />will be used for surface and underground mine needs. This will include fire protection. <br />An underground water well will supply potable water for the mining complex. This <br />water will be pumped from the well to the potable water storage tank. Mine water wilt <br />also be pumped to the mine water storage tank. Because water for both storage tanks will <br />be pumped, the need to access to the water tanks will be minimal. It is estimated that one <br />to two trips per week to the storage tanks will be adequate to provide the required <br />maintenance and security for the tanks. <br />This section of road will have very limited travel and will have a relatively flat grade. <br />Refer to Figure 1-Site Facilities for the general layout of the Water Tank Access Road <br />and Figure 4 for a typical cross-section for this road. All drainage from the Water Tank <br />Access Road will report to the sediment pond. <br />Stockpile Access Road <br />Access to the coal stockpile area will be from the proposed haul road. Because of the flat <br />nature of the storage site, there are no designated roads. Vehicles will be able to drive <br />unobstructed throughout the storage azea. To prevent surface erosion due to traffic, this <br />area will be graveled. All surface drainage from this area will report to the sediment <br />pond. <br />-2- <br />n <br />LJ <br />
