• CYCC plane to reestablish approziaate premining geometry and <br /> gradient of ephemeral stream chanaela that have been disturbed by <br />the mining and reclamation operations at Mine No. 3. To accomplish <br />this, backfilling and regrading operations will be conducted to <br />achieve approzimate original contour and replace original gradient <br />and morphology of ephemeral stream channels, poatmining topography <br />is shown on Map 12, Mine No. 3 Poatmining Topography. <br />Stream Buffer Zones <br />Significant protection of surface eater quality has been <br />achieved through the identification and marking of stream buffer <br />zones. No streams classified as intermittent or perennial will be <br />• diverted. Stream buffer zones have been identified on Map 20, <br />Permanent Sediment Control Plan. These zones are marked in the <br />field with highly visible markers placed close enough together so <br />that at least one marker is visible at any point along the boundary <br />of the buffer zone. The buffer zones will provide that no <br />disturbance will be located so close to a stream which meets the <br />criteria of Rule 4.05.18 (3) that either physical disruption or <br />uncontrolled sediment contribution might occur. The Mine No. 3 <br />Detention Basin, proposed Middle Creek Mine Detention Basin, two <br />dugout sumps east of the inactive Middle Creek Daderground Mine <br />Portal Area, and access road are the only eziating or planned <br /> diaturbaacea located within 100 feet of the intermittent stream <br />• qualifying for buffer zones. The sedimentation ponds, which are <br />2.05 - 144 <br />
