No.:Ice of Viola:: <br /> Attachment A <br /> Portions of the Ooeration to which this Notice .Acelies : <br /> Road C <br /> 1 . The drainage ditch along the entire road does not meat design <br /> requirements . The ditch is intermittently scoured and filled in with <br /> sediment or large rocks . Rock checks required by the approved plan have <br /> not been installed . In some locations , bedrock outcrops have prevented <br /> ditch excavation. <br /> 2. At Sta. 95+00 (approximate) , road drainage has been intercepted by an old <br /> pilot road which runs above and parallel to Road C to its point of origin <br /> at Sta. 54+00. Uncontrolled discharge from the pilot road has resulted in <br /> erosion above Road C and sediment deposition in Road C drainage ditch at <br /> multiple locations , including cut slope gullies at 82+00 and 63+50. <br /> 3. Evidence that road ditches had been overtopped with resulting rill <br /> erosion on road surfaces and fill slopes was observed between Sta. 122+00 <br /> and RO-3 outfall at 92+00, from 92+00 around switchback to 83+00, between <br /> 76t00 and 71+00, and around the switchback between 36+00 and 34+00. <br /> Road DA <br /> 4. Drainage ditch from Road D to Mine 2 bench does not meet approved <br /> design. The ditch was intermittently scoured and filled in with <br /> sediment. There was some rilling on the road surface , and it appeared <br /> that some drainage from the mine bench may have overtopped a low berm and <br /> run down the road . <br /> Road D <br /> 5. The drainage ditch along the entire road does not meet design <br /> requirements . The ditch is intermittently scoured and filed in with <br /> sediment or large rocks . Rock checks required by the approved plan have <br /> not been installed. In some locations , bedrock outcrops may have <br /> prevented ditch excavation. <br /> 6. At Sta. 117+00, a culvert whic�I passes beneath the road and conveys <br /> drainage from above to a "BAT" pond series below the road fill partially <br /> blocks the drainage ditch and has resulted in overtopping of the ditch. <br /> 7. The road surface between the Mine 1 Bench and Sta. 100+00 is sloped to <br /> the outside , and the road fill along this segment is heavily Tilled . <br /> -1 - <br />
