III. COMMENTS -COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. • Ponds 1, 2 and 3 were dry, but there was dried mud on the bottom of all three, criss-crossed with mud cracks. Pond 4 was dry, and the bottom was covered with tall grasses. There was no indication that water has been impounded in this structure. Bin wall impoundment structures for Ponds 1-4 appeared to be stable and functioning as designed. • The West Ridge sedimentation pond was dry, but the bottom was covered with deeply- cracked mud, indicating that water had been impounded earlier this season. Pond slopes were stable, and covered with vegetation above the normal water line (Figure 4). Primary and emergency spillways were clear (Figure 5), as was the ditch that flows eastward from the pond spillway. • Reclaimed surface drainage, including the riprapped channels (Figure 6), at the East Mine is in general conformance with Map 6A-5D of Volume 6A of the permit application package. Ditches will be studied in greater detail during a future inspection. Culvert Pipes, as labeled on Map 8-1 - "Drainage Plan &Topsoil Storage Areas" • "A" has been removed and replaced with an open ditch. • "B" has been removed. • "C" has been removed or sealed with the reclamation of the crushing and screening bench, and replaced by the lower portion of the riprapped channel. • "D" has been removed or sealed. • The inlet and outlet of "E" were clear. • The outlet end of "F" was clear, but the inlet appeared to be buried. Straw bales were placed in the ditch at the approximate location of the inlet. • "G" has been removed and replaced by an open ditch with erosion BMPs in place. • "H" has been removed or plugged. • "I" remains in place; the inlet had been recently cleared and the outlet was protected from the reclaimed side slope of the roadway with straw bales. • "J" remains in place. • "K" has been removed or sealed. • The inlet for "L" is protected with concrete slope paving. The drop inlet in the middle was no longer visible. Basil Bear explained that it had been covered over with a steel plate, and backfilled with the realignment of the haul road curve. • "M" has been removed or sealed, replaced by the upper portion of the riprapped channel. • "N" was clear at both the inlet and outlet ends. • "N 1" includes twin culverts on the northwest corner of the West Ridge waste pile. The inlets were completely blocked with sediment, and the outlets were approximately 90% obscured. Basil Bear said these culverts had been inadvertently missed during the reclamation, but would be removed shortly. • The ditch and inlet to "O" had been recently cleaned. The outlet was clear. • "P" has been removed or sealed. • "Q" continues to carry flow to the West Ridge sedimentation pond. • Inlet and outlet ends of "R" were clear. Backfill & Grading • Backfill and grading operations are essentially complete for reclamation of the East Mine. The reclaimed slopes have been roughened by using an excavator bucket, and there was Bowie No. 1 Mine C-1981-038 19-21 Aug-2009
