September 25,2019 G1996-083/Bowie No. 2 Mine RDZ <br /> Pond J was holding a significant volume of water(still a good 10 feet or more below the emergency spillway). It <br /> receives seepage from the Fire Mountain Canal and from irrigation water. Basil Bear indicated that the problem <br /> with irrigation water entering the pond has been addressed. A contractor will remove trees and shrubs from the <br /> embankment,and this work is being directed by the power company(DMEA)because of overhead wires. This <br /> structure should be watched closely for any signs of instability. <br /> Ditch D-F4 still requires attention due to extensive erosion. BRL has stockpiled rocks and other material for <br /> this project,but equipment problems have stalled the work. No problems were seen with other ditches. <br /> The structures affiliated with the diversion gate at Curve 8 has been cleared of sediment. <br /> PROCESSING WASTE/COAL MINE WASTE PILES—Rule 410 and 4.11 <br /> Drainage Control; Surface Stabilization; Placement: <br /> No erosion or other problems were seen on Gob Pile#1. <br /> Gob Pile#2 is graded well, and no erosion was seen on the hillside above it,below the diversion ditch. Two small <br /> seeps were seen near the bottom of Gob Pile#2, approximately 100 feet up the hill from the VWP-09 piezometer <br /> and the BG05-07 inclinometer. Cattails and white residue on the soil (a salt precipitate)were observed. BRL <br /> needs to pay close attention to these and other seeps and address them in quarterly waste bank reports. <br /> Work was being done on Gob Pile#3 on the morning of the inspection, and a great deal of material needed to be <br /> spread and graded. <br /> No issues were seen with Gob Pile#4. The reclaimed portions contain good vegetation cover. <br /> ROADS—Rule 4.03 <br /> Construction 4.03.1(3)/4.03.2(3),Drainage 4.03.1(4)/4.032(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, including the road to the Terror Creek Vent Shaft. The hillside above Curve 8, <br /> which is armored with boulders, is stable. <br /> REVEGETATION—Rule 4.15 <br /> Vegetative Cover; Timing: <br /> Halogeton(a C list weed species)was seen again at Gob Pile#2. Basil Bear has suggested that he not treat it <br /> because it provides erosion control. DBMS will take this under consideration,but BRL should watch closely to <br /> see if this weed spreads, and,if so, use herbicide to stop it. <br /> Number of Partial Inspection this Fiscal Year: 3 <br /> Number of Complete Inspections this Fiscal Year: 1 <br /> Page 3 of It <br />
