May 25, 2011 C- 1981 -035 /King Coal Mine MLT Surface Water Monitoring 4.05.13; Drainage — Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: • Mr. Jarvis said the permit area had received 1.25 inches of rain over the course of two days during the week prior to this inspection. This precipitation event afforded Mr. Jarvis the opportunity to closely observe all of the ditches, pipes and ponds, to ensure that each was functioning as it was designed to function. • At the King I facility, the East and West Sedimentation Ponds both held water, at levels below which discharge would occur. The outlet pipe for the primary spillway at the West Pond was clear. Pond side slopes and embankments appeared to be stable and reasonably well vegetated. • The sedimentation pond for King II was nearly dry, but moist soil creating a visible "bathtub ring" in the pond indicated that the pond had held water recently (Photo 5). No discharge was occurring from the pond. The outlet structure appeared to be structurally sound. No discharge had occurred as a result of the precipitation event. • GCC will be submitting a Revision application in the future addressing excavation of the channel downstream of the sediment pond outlet so that positive drainage will occur. • The east and west clear water diversion ditches at King II both appeared to be well maintained, with no signs of erosion or sediment accumulation. • All culvert pipes and ditches within the King 11 disturbed area were clear and well maintained. BMPs protecting the drop inlets have been recently refurbished (Photo 6). • A rock dust silo is located at the upper end of the King 11 facilities area (Photo 7). Mr. Jarvis said the drainage around the silo will be reworked, and the entire ditch enclosed in a buried culvert. • Sediment from the cattle guard at the entrance to King 11 had been cleaned out, and erosion logs were installed at the downstream and upstream ends to trap sediment. TOPSOIL — Rule 4.06 Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; Redistribution 4.06.4: • The topsoil stockpile at King II appeared to be stable and protected from erosion. • A flush of Blue Flax was appearing across the surface, along with some yellow sweet clover (Photo 8). EXCESS SPOIL and DEVELOPMENT WASTE — Rule 4.09 • Placement; Drainage Control; Surface Stabilization: • There appear to have been no recent changes made to the coal mine waste pile located at King I. • The road leading up the face of the pile was in good shape, with no visible drainage problems. • The riprapped ditches along the north and south sides of the pile appeared stable. • No new coal mine waste from operations at King II has been hauled to the top of the pile in Number of Partial Inspection this Fiscal Year: 7 Number of Complete Inspections this Fiscal Year: 3 Page 3 of 10
