Pond water levels (and corresponding sediment load) will be visually monitored and recorded weekly by <br /> on-site personnel using a staff gauge. Records of the visual measurements will be maintained on-site. A <br /> copy of the form to be used for pond level monitoring and sediment removal is included with this TR. <br /> When process water levels approach the minimum freeboard(three feet), sediment will be excavated from <br /> each of the ponds as necessary to return them to acceptable operational levels. To avoid interaction of the <br /> process water with groundwater, the sediment pond will not be excavated beyond the base of the existing <br /> ground surface. The excavated pond sediment is used as subbase fill in the reclamation process, where it <br /> will be placed as needed, graded, then covered with topsoil and seeded in accordance with the <br /> Reclamation Plan. <br /> Reclamation <br /> Affected areas will be reclaimed within eight months after completion of mining so as to coincide with <br /> summer and fall months in accordance with the reclamation plan(Exhibit E of the Permit). The remaining <br /> period of active mining is estimated to be 20 years. <br /> Page 3 of 3 <br />
