(b)(i) A plan for control of surface and ground water drainage. <br />As explained in (a)(i) above, six sedimentation ponds have been constructed <br />to control surface water drainage through the surface facilities area. Other <br />surface drainage from the permit and adjacent areas is allowed to flow <br />through ephemeral channels unimpeded by the mining operation. Ground <br />water drainage concerns are isolated to potential mine discharge. This <br />ground water drainage, if any, will be treated in underground sumps and <br />discharged to the surface in accordance with NPDES permit requirements. <br />(b)(ii) A plan for treatment and for surface and ground water drainage. <br />Surface run-off from the facilities area should not require treatment, other <br />than detention time provided by the sedimentation control ponds or treatment <br />with alternative sedimentation control. Mine discharge will be treated in <br />underground sumps if required. <br />PR -14 2.05-114 03/14 <br />
