(5) 'the ponds will be unlined. Water seepage ~rom the • ponds will depend upon the time of year and the hirght of any groundwater table. ~ I (6) The ponds will be cleaned periodically and ~he fines or sediment will be used in reclamation. (7) Three other existing dams in the disturbed areas of the North Central Phase will not be further used or disturbed. (8) The new ponds will not be sealed. Water will be allowed to percolate through the ground and retur to the groundwater systems. No chemicals will be adde to the water. Therefore, once the suspended solids are filtered out, the water quality will be essentially unchanged. (9) During mining, some groundwater will be enco ntered. This water will be transported in association ith the material taken Eor processing. After processing, t e water will be piped to tfie pond and will gradually seep b ck into the groundwater. There should not be a signifi ant net change in the quantity or quality of groundwater. Areas of Disturbance There are existing private and state roads to provid access to the entire permit area. Additional haul ro ds, if required, will be within the permit boundary. S nce the area is relatively flat, only slight grading w uld be required for haul roads from the excavated cuts to the processing plant. Acreage of major, moderate an minor disturbance are presented in Table 2. The figures are Eor all acres requiring bonding, including acres undergoing revegetation for a two-year period. (1) Major disturbances will include areas being excavated or backfilled with spoil materials. Backfilling will be continuous with excavations. (2) Areas of moderate disturbance include the processing plant work areas, on-site roads, ore stockpiles nd the impoundments. (3) Areas of minor disturbance are those and rgoing reclamation and topsoil stockpiles. These areas ill be staked in the field with steel posts and colored lags to indicate the extent of disturbance. 13
