November 5, 2014 C- 1996 - 083 /13owie No. 2 Mine SLB The unidentified /unapproved culvert near Topsoil Stockpile F had been removed. During the October 15, 2014 Division inspection, Division inspectors identified drainage control problems along the conveyor belt line between Topsoil Stockpile A and the Water Tank bench. Culvert B26 had become silted in, and ditch B37 had not been maintained to direct flow to culvert B 13, resulting in a gully forming to carry flow to B Gulch. In an effort to remedy the gully, the operator had constructed a ditch that ran parallel to culvert B13. The ditch was not a permitted structure, so the Division directed BRL to remove the ditch or request approval to add it to the drainage plan. BRL has elected to remove the ditch, but work had not been completed at the time of the inspection. The ditch should be removed, and the inlet to culvert B26 cleared within 2 weeks of issuance of this November 5, 2014 inspection report. The sediment control structures (wattles) in place at the road crossing near the confluence of East and West Terror Creek were functional and in good condition. The operator had recently replaced some of the wattle material. The inlet sump at culvert K2 had been recently maintained; the culvert was clear and the sediment level was below the culvert inlet. Ditch C19, south of the office, had been regraded and the jersey barriers reset out of the ditch flow line. Silt fence had been installed at SAE 10, to ensure that runoff from the yard area will be treated before it enters the Deer Creek Trail Ditch. The silt fence was correctly installed in the appropriate location to protect the ditch water. Straw bales had been added around the Deer Trail Ditch pump house to augment existing bales and ensure that sediment from the pump house yard disturbance does not enter the Fire Mountain Canal. Ditch D -F4, along the eastern edge of Gob Pile #2, identified as needing maintenance during the October 15, 2014 inspection, had not been addressed at the time of this inspection. Ditch D -F4 should be maintained as designed within two weeks of issuance of this November 5, 2014 inspection report. OTHER (SPECIFY): Trash and debris observed near Topsoil Stockpile F, the B Portal Bench, and on the lower bench of Gob Pile #2 during the October 15, 2014 inspection had been removed. During the October 15, 2014 inspection, the Division observed that the loadout conveyor storage building and yard were located outside of the approved permit area and disturbance area boundaries. BRL is addressing this permit defect with Technical Revision No. 91, currently under review.
