December 20, 2016 C-1981-012/New Elk Mine RDZ <br /> <br /> <br />Number of Partial Inspection this Fiscal Year: 4 <br />Number of Complete Inspections this Fiscal Year: 2 <br /> <br /> Page 3 of 8 <br /> <br /> <br />Containment Area #5 was holding ice and water, but it was well below th e top of the structure, and there was no <br />sign of discharge toward State Highway 12. No problems were seen with Containment Areas 3 and 4. <br /> <br />Willows have been cleared out of the ditch south of Pond 007A and the large SAE (possibly ditch D28 but this <br />needs to be clarified). <br /> <br /> <br />PROCESSING WASTE/COAL MINE WASTE PILES – Rule 4.10 and 4.11 <br />Drainage Control; Surface Stabilization; Placement: <br />The upper RDA (un-reclaimed portion) was covered with snow, but it appears that it is well graded. Work is <br />required to spread piles of material. <br /> <br />Runoff from the upper RDA flows through ditches and sumps and eventually to Pond 08; it does not appear to <br />flow directly onto the reclaimed portion of the RDA as the ditch at the interface (between reclaimed and un - <br />reclaimed areas) appears to be functioning. This ditch is very important and has been re -defined (cut deeper) <br />during the 2016 maintenance season. Also, an additional sump and riprap lining have been added on the east side <br />of the RDA. <br /> <br />No erosion was seen on the face of the lower RDA (reclaimed portion) or in the side ditches. <br /> <br /> <br /> <br />ROADS – Rule 4.03 <br />Construction 4.03.1(3)/4.03.2(3) <br />Drainage 4.03.1(4)/4.03.2(4) <br />Surfacing and Maintenance4.03.1(5) and (6)/4.03.2(5) and (6) <br />Reclamation 4.03.1(7)/4.03.2(7): <br />The road to the RDA appeared to be in good shape. Below this road, some sediment control practices are still <br />recommended on the toes of the fill slopes. <br /> <br />TOPSOIL – Rule 4.06 <br />Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; Redistributio n 4.06.4: <br />The ring ditch around Topsoil Stockpile #2 is intact, and an outlet, with silt fence, has been added in recent <br />months. There was no significant erosion visible on this pile. <br /> <br /> <br /> <br />
