PM -2D, a rock -lined drainage channel routing runoff to T -26 is in good condition. New rock check dams <br />are in place and appear to function as designed (channel was dry at the time of inspection). <br />PM -4 was dry during the inspection but regularly receives runoff. This channel is in a steep slope and has <br />historically been difficult to stabilize. SCC has placed geotextile material and rip rap in the channel. <br />Vegetation is establishing through the fabric, which is helping to stabilize the surface. A roughly 25' <br />section of the channel has down -cut through the fabric and rip rap (see photo #11588). SCC plans to <br />repair this area under regular rill and gully maintenance this summer. This repair will be conducted with <br />hand tools to avoid bringing machinery onto the slope. <br />Sedimentation Ponds and Impoundments (Rules 4.05.5; 4.05.6; and 4.05.7): <br />Stock pond T -2 was holding water but not discharging. Arrowleaf balsamroot (a desirable species) is <br />abundant in this area. <br />T -3 was holding water but not discharging. The white- flowered plant on the pond's outside embankment <br />looked similar to hoary cress (Cardaria draba, a List B noxious weed), but is actually pennycress (Thlaspi <br />arvense), which is not a noxious weed in Colorado. <br />T -5 was holding water but not discharging at the time of inspection. Vegetation is well established in the <br />open channel rock -lined spillway. <br />T -18 was holding water but not discharging at the time of inspection. There is minor rilling in the slope <br />between T -18 and T -20. Straw bales have been placed to help control area runoff (see photo #11589). <br />T -20 was holding water but not discharging at the time of inspection. The rock -lined inlet and discharge <br />structures are intact. <br />T -24 was dry at the time of inspection. All embankments appear stable and well vegetated with <br />herbaceous species. <br />T -26 was holding water but not discharging during the inspection. All embankments are stable. <br />T -27 was holding water but not discharging. There is some minor rilling in the slope above this area, <br />which should be monitored. <br />Pond 16 was discharging during the inspection. The rock -lined discharge channel measures <br />approximately 15' wide, the embankment width (at top) measures approximately 15' and the outside <br />embankment slope measures approximately 17'. The inlet channel is rock lined and stable. SCC plans to <br />submit a Technical Revision to add a culvert which will allow vehicular travel over this channel. <br />Pond 17 was discharging during the inspection. The primary discharge culvert measures 36 ", the <br />embankment width (at top) measures approximately 15' and the outside embankment slope measured <br />approximately 17 °. <br />Roads Rule 4.03 et seg.): <br />Haul Road K measures approximately 15' across and has a slope of approximately 3' by Pond 16. Haul <br />Road A measurement approximately 20' wide with a 5' slope by T -5; 21.5' wide with a 5° slope by T -3, <br />and 24' wide with a 4.6° slope by T -2. These measurements appear typical of permanent roads within the <br />permit area. <br />Page 12 <br />
