Yoast C-94-082 Pg 2/3 25 Aug 04 ~- Hydrologic Balance (cont.): The emergency spillway for pond 013 is a riprapped open-channel. The spillway appeared to be stable at the time of the inspection. - The construction of the embankment for Pond Oi 1 A has just been completed. There is still some final grading and riprapping work that needs to be completed at the inlet. The pond contained a small amount of water at the bottom but was obviously not discharging. There is no vegetation on the embankment but Roy Karo indicated that the area would be seeded this fall. The emergency spillway is a riprapped open-channel. The emergency spillway still needs more riprap to complete it as well. Overall the pond appears to have been constructed properly and appears to be stable. The Division needs and as-built certification for this pond. - Pond O1 1 contained water several feet below the discharge pipe and was not discharging at the time of the inspection. The discharge from pond 011 A will flow into this pond. The embankment had some vegetation and appeared to be stable at the time of the inspection. No erosional problems were noted on the pond embankment. The emergency spillway is a riprapped open-channel. The spillway appeared to be stable at the time of the inspection. -The drainage from pond O1 1 A to pond O1 1 has been reworked, as required by the Division. There are rock check dams in the drainage spaced approximately 50 feet apart in the upper portion (approximately the upper half) of the area. The check dams appear to have been properly installed and keyed in to the side slopes of the drainage. The check dams on the lower portion are further apart than those on the upper portion. (The Division will need an as-built certification for this drainage to ensure that it has been constructed as requiredj. There is a fairly large "sump" at the bottom of the drainage that empties into pond Ol 1. Roy Karo has stated that the outlet of this sump will be riprapped for increased stability (there is a fairly large pile of riprap at the top of the drainage - by pond Ol 1 A). - Pond O10 contained water approximately two feet below the discharge pipe and was not discharging. The pond embankment was well vegetated and appeared to be stable at the time of the inspection. No erosional problems were noted on the embankment. The emergency spillway is a riprapped open channel. The spillway appeared to be stable at the time of the inspection. -There was no water in any of the open pits at the time of the inspection. -All of the ditches along the haul roads were well vegetated and appeared to be stable. The culverts were all clear and appeared to be functioning properly. Backfilling and Grading: It appeared that most of the areas that were not being actively mined or that remained open for the highwall miner were backfilled. The open areas include the lowest portion of the Neck Pit, the Valora Pit, The upper portion of the Wolf Creek Pit and the Scraper Pit. The operator was not doing any backfilling or grading operations at the time of the inspection. Topsoil: -All of the topsoil piles were well vegetated and marked. No erosional problems were noted on any of the piles. - Topsoil has been stripped from the area north of the Scraper Pit and live-hauled to the south area of the Wolf Creek Pit that has recently been backfilled.
