Mine Site Inspection Mine Name: Bowie #2 Mine Permittee: Bowie Resources, LLC Permit ID #: C-1996-083 Inspection Date: April 26, 2018 9:30 — 2:00 Weather Conditions: Warm, clear skies, dry ground Participants: Christine Belka, Office of Surface Mining (OSM) #182 Bill Bear, Bowie Resources, LLC Janet Binns, Division of Reclamation Mining and Safety (DRMS) Clayton Wein, DRMS Field Fvaluafinn Bowie #2 is an inactive, non -producing, underground coal mine in Temporary Cessation status. All portals and vent shafts have been permanently sealed and are fenced to prevent access. Underground mining equipment has been removed and salvaged or buried in place. Light excavation work is being conducted along the road to the office in an attempt to find leaks in buried water pipes. Signs and markers: Mine identification signs are in place at all points of entrance from public roads and contain all information as required under Rule 4.02.2. PVC pipes on t -posts mark the disturbed perimeter within the permit area as required under Rule 4.02.3. Explosives storage: This mine's ATF (explosives) permit has been terminated. The explosives storage containers are empty. Topsoil: All topsoil piles observed were stable, well -vegetated, and marked with appropriate signs. Hydrology / sediment control: Bowie Resources has placed trash racks on culvert inlets. This helps ensure debris does not get lodged within the culvert. All observed culverts were in good repair and functional condition with two exceptions: 1) The culvert on the south side of the Fire Mountain Canal Bridge is approximately 40% clogged at the outlet and should be cleaned, and 2) the inlet of the culvert routing water from the gob piles to Pond D is damaged. Sediment has accumulated in this sump and the top of the culvert has been bent down, decreasing the flow capacity. Recommend cleaning the sump and pulling the culvert open to ensure adequate flow capacity. Six sedimentation ponds were inspected; all were in good repair with adequate storage capacity and well -vegetated embankments. None of the ponds were discharging at this time. Pond B held a very small amount of water. Pond C was holding water but not near the discharge level. Mr. Bear indicated that this pond was cleaned last year. A small tree is growing on the upper outer embankment and the group discussed whether this may present a piping / embankment stability concern. We decided that it did not at this time. Pond D was holding a small amount of water but not discharging. The inlet culvert routing water to Pond D from the gob piles is slightly damaged. As noted above and listed below, this culvert should be repaired. Pond F was holding water but not discharging. This pond has accumulated a sediment fan at the inlet and is scheduled to be cleaned this year. Pond J was holding a small amount of water. Pond K was dry and stable. Roads: All roads traveled were in good repair with proper drainage structures.
