• i <br />2. Confine mine dewatering to an area within the slurry wall to mitigate <br />against impacts on neighboring shallow residential wells and, <br />3. Eliminate the need for a permanent water augmentation plan. <br />The applicant will fill the ponds and maintain the pond water levels with surface <br />water rights owned by the Stegner family. <br />The presence of the lined pond system will serve as a barrier to ground water <br />flow in the immediate vicinity of the operation. This could result in a short-term, <br />localized mounding of ground water in the northern, up-gradient direction and a <br />water surface depression on the down slope side of the lined ponds. This will <br />stabilize over time to approximately pre-mining ground water levels. <br />The applicant proposes to construct a drain system around the exterior perimeter <br />of the lined ponds to transfer any surplus water from the up gradient side to the <br />down gradient side via ditches or pipes. This will eliminate the <br />mounding/depression effect. This system will be installed at the pre-mining <br />ground water surface to ensure maintenance of the pre-mining ground water <br />table. <br />Once these two systems have been installed, overburden and topsoil will be <br />stripped from the Phase I area. It is proposed that certain areas outside of the pit <br />boundaries be filled to build up the land above the ultimate pond water level. <br />~z <br />
