PM-8 requires repair and placement of additional riprap. The drainage density above and <br />to the west of PM-8 is not sufficient to protect topsoil and vegetation and reduce erosion. <br />Additional channels and/or reconfiguration of the drainage design were recommended by <br />the DMG as indicated in the June 2004 inspection. <br />Construction of PM-3 and PM-18 has not been completed as is indicated on Exhibit 13-2, <br />Backfill and Grading Schedule. <br />Erosion is another concern at the Seneca II Mine. Rills and gullies were identified in the <br />azea of the ells fence surrounding the shrub establishment area. Several gullies are <br />located above and to the northeast of the shrub establishment area. The rills and gullies <br />aze also generally identified in the 2004 Rill and Gully Survey. The survey indicates that <br />the rills and gullies will be re-graded as necessary. Based on recent inspections, it <br />appeazs that the gullies will continue to worsen and repairs should be made to reduce <br />further erosion as soon as practicable. <br />Weed control is an issue at Seneca II. Troublesome weeds aze evident at many locations <br />throughout the mine site. Canada Thistle is most notable and prevalent in many locations <br />including: Pond 004 embankment, along remaining permanent roads, Wolf Creek Pit <br />area, Wadge Pit azea, and the Pecoco Impoundment. Houndstongue, Scotch Thistle, and <br />Whitetop have also been identified. In SCC's last Annual Reclamation Report, they <br />indicated that in 2003 spraying was limited only to the facilities azea and the county road <br />leading to the Pecoco Pond. <br />
