November 19, 2019 C-1996-083/Bowie No. 2 Mine RDZ <br /> PROCESSING WASTE/COAL MINE WASTE PILES—Rule 4.10 and 4.11 <br /> Drainage Control; Surface Stabilization; Placement: <br /> BRL is trying to prevent erosion on Gob Pile#2 and appears to be successful at this time. The water bars are <br /> functioning, as are the sump and wattles at the east end. The seeps below Gob Pile #2 had only white precipitate; <br /> no rust or other colors indicate iron or other metals. Some soil piles on Gob Pile#2 (possibly from ditch or <br /> pond cleaning) should be spread to avoid ponding of water on the pile.Alternatively,the piles could be <br /> aligned in rows perpendicular to contours to prevent ponding. <br /> No ponding or other issues were seen on Gob Pile#3. Additional grading will be needed prior to winter. Recent <br /> compaction testing has been performed at four levels,per Basil Bear. <br /> No problems were seen with Gob Pile #1 or Gob Pile #4. <br /> ROADS—Rule 4.03 <br /> Construction 4.03.1(3)/4.03.2(3),Drainage 4.03.1(4)/4.03.2(4), Surfacing and Maintenance4.03.1(5)and <br /> (6)/4.03.2(5) and(6),Reclamation 4.03.1(7)/4.03.2(7): <br /> No problems were seen with roads or the hillsides below them. The hillside above Curve 8,which is armored with <br /> boulders,is stable. <br /> SLIDES and DAMAGE - Rule 4.12: <br /> It appears that slumps have not moved significantly in the recent past. These include slumps by the B Portal and <br /> by Curve Number I I along the Haul Road. <br /> SUPPORT FACILITIES - Rule 4.04: <br /> Berms were found to be functional at several pads,including the Utility Bench, the D Portal Bench, the storage <br /> pad east of the D Portal,the B Portal bench, and the Coal Stockpile Pad. <br /> The dirt piles by the Hubbard Creek Coal Gas facility(next to the Utility Bench)have been moved. <br /> Coal residue under the conveyor has not been moved due to safety concerns. It will be addressed when the <br /> conveyor is reclaimed,per Basil Bear. This material should be watched closely to see if it is being blown onto <br /> undisturbed areas by wind. <br /> Number of Partial Inspection this Fiscal Year: 5 <br /> Number of Complete Inspections this Fiscal Year: 2 <br /> Page 3 of 13 <br />
