Pond B Sump The Pond B Sump is a settlement pond for water before it enters Pond B(see Figure 1). Mr. Nettleton notified us that he would clean this pond before winter (it was last cleaned in spring, 2011). This is necessary to ensure that there is adequate freeboard and that the system is not stressed. The material will be placed in the inactive area of the refuse pile and windrowed so that it may completely dry. Mr. Nettleton also stated that TCC would do maintenance on the culvert (flush it) to alleviate the increased sediment. Pond D This pond is located on the west side of the facilities area. TCC replaced the riser in the outlet culvert in the past two years. Pit Pond The Pit Pond pond receives runoff from the refuse piles and upland reclaimed areas. It is an incised pond that does not discharge. The pond contains a pump station that administers pressure relief. 6MN Pond During DRMS' September 12, 2011 inspection, Mr. Musick noted additional erosion occurring to the west of recent repair work. A ditch has been (partially) constructed to reroute sediment away from the pond (see Figure 2). The steep pond slopes are cause for concern since they continue to form erosion gullies (see Figure 3). Mr. Nettleton agreed to repair and reseed the embankments by November 30. All other ponds were functioning as designed. Fish Creek Tipple The Fish Creek Tipple Facilities have been demolished (see Figure 4). This area housed the loading and wash facility for the Middle Creek Mine. There is still some scrap metal on site, and the sidetrack will remain. Mr. Nettleton stated that the truck tunnel has been removed, and backfilling and grading will occur next year. Per lessee request, TCC is leaving the coral for grazing purposes. TCC recently repaired the Fish Creek Tipple A Pond's 30 inch inlet culvert that had failed (see Figure 5). This outlet discharges to Foidel Creek. Before the fall ends, TCC will repair /seed the disturbance that resulted from this repair work. Cuttings Pit TCC removed the pit's twenty -foot highwall, and graded and seeded the Cuttings Pit area last year. Mr. Nettleton stated that they were considering implementing the normal husbandry practice of interseeding for vegetation success. The power lines will be left for the time being (see Figure 6). Northwest Mains Vent Fan As a result of a landowner complaint, work has been done to reduce the noise coming from the discharge fan. All of the mechanical equipment was foamed and the exhaust pipe was turned
