3) Culvert Replacement/Ditch Maintenance <br /> A.) Approximately 1800' up the mine access road, located between the sharp curve <br /> to the east and the upper mine bench, an 18' length of 24" CSP has been installed to <br /> pass flow from the outside road ditch through the road berm. The outlet end of the <br /> CSP has been winched or otherwise bent to the point that it is no longer functional. <br /> The CSP segment needs to be excavated and removed from the site,and replaced with <br /> a new 18' segment of 24" CSP. The 18' length is necessary so that discharge from <br /> the outlet will fall onto competent sandstone ledges lower on the slope rather than <br /> erode into the road embankment. The new CSP needs to be set in the original <br /> location, covered, compacted, and the road berm rebuilt to its original dimensions. <br /> B.) A short distance up the road from the CSP described above, another 24" CSP, <br /> approximately 40' long, passes flow from the inside road ditch to the outside road <br /> ditch. This CSP is plugged with sediment at its lower end, and needs to be cleaned <br /> out. The short ditch segment (approximately 10 feet) between the CSP outlet and the <br /> inlet to the CSP to be replaced has filled in with sediment and needs to be cleaned out. <br /> C.) A segment of the inside road ditch beginning approximately 90 ' up the road from <br /> the inlet to the 40' CSP, and extending up along the road for approximately 60' has <br /> filled in and needs to be reestablished. The ditch will be reconstructed to be at least <br /> 30" wide and 1 ' deep with 2:1 side slopes. A 4' X 4' X 4' sump will be excavated at <br /> the inlet to the 40' CSP and compacted to provide proper alignment and discharge into <br /> the CSP <br /> 3 <br />
