_ (iv) The Roadside South permit area was entered from the existing Roadside South <br />• Portal. New mine openings from the surface within this permit area are not <br />planned. <br />(b)(i) Surface water runoff is controlled by channeling water from disturbed areas into <br />sedimentation ponds. This water is not discharged into the natural water <br />system unless a precipitation event significantly greater than a 10-year, 24-hour <br />event occurs. The complete plan for sedimentation control is contained in Tab <br />Section 13. <br />Surface water runoff in the Roadside South permit and adjacent area will not be <br />affected by underground mining operations. Groundwater drainage into the <br />mine workings will be controlled and discharged as stated in Section <br />2.05.6(3)(a)(iii) by existing facilities at the Roadside Mine. <br />• (ii) Groundwater from underground.workings is directed to underground sumps or <br />abandoned areas for settling prior to pumping into the mine water distribution <br />system or discharging outside. <br />The coal preparation plant is primarily a closed water system. Make up water <br />to replenish water lost on clean coal and refuse is taken from mine water and <br />Palisade Domestic water. The refuse fines circuit uses flocculent and coagulant <br />to settle the fines. the anionic and cationic attraction of these chemicals bonds <br />multiple clay particles together which promotes settling. This settled material is <br />disposed of as part of the refuse from the plant. Minimal hydrologic impact is <br />expected from runoff over the refuse. See Appendix 17-1 for copies of the <br />MSDS sheets for these chemicals. <br />. 17-4 (Rev. 12/16/96) <br />
