i , <br /> 1 .. <br /> Road maintenance needs:Ash Pit Road(left) and access road to Middle Flume ponds <br /> (substation on right of photo is near East A Pitt <br /> Hydrologic Balance <br /> Water is trickling out of the primary spillway below Coyote Pond. This is likely caused by seepage <br /> into the horizontal inlet pipe that is under several feet of water and sediment below the pond surface. <br /> This is not likely a problem, but should be continually monitored; an increase in the flow rate could <br /> indicate damaged pipes in the spillway. <br /> Some ponds were discharging during the inspection. These include the East Pyeatt ponds, Johnson <br /> Gulch ponds, and No Name ponds. <br /> Several sediment ponds were observed, and the following maintenance issues were observed: <br /> • For several ponds the access roads require maintenance. In particular, see comments and <br /> photos below for Oak Gulch Pond.Also, this includes the roads for No Name #4 and Middle <br /> Flume #3. <br /> • For several ponds, access for cleaning should be improved. <br /> • For most ponds observed, sediment level markers are missing. This problem should be <br /> rectified. <br /> • East Flume #1 and Johnson Gulch 46 have burrow holes in embankment, which should be <br /> filled. <br /> • East Pyealt#1, East Middle Flume and sediment traps above it, and sediment trap above <br /> Johnson Gulch IOR are in need of sediment removal. <br /> • Banks at No Name#2 require regrading and possible armoring. <br /> • The asphalt rundown from Impoundment H has a small crack that requires repair. <br /> The inspection indicated no water quality problems, such as oil and grease or turbid water, at any of <br /> the pond discharge points. <br /> Above the Oak Gulch Pond, a large gully has formed (approximately 10 feet deep at some locations) <br /> due to the creek jumping its banks and running down the access road. Graham Roberts and Division <br /> staff discussed the option of re-routing the road to a higher location and allowing the current road to <br /> act as a channel. It would need to be filled and armored. The option of restoring the historical <br /> channel to prevent flow onto the road could also be considered. TMI should submit a preliminary plan <br /> (possibly with multiple options) to the Division and options can be discussed prior to a formal <br /> submittal. <br /> Due to the large gully in the road, the Oak Gulch Pond is full of sediment. <br />
