portions of the roads to minimize compaction and encourage <br /> infiltration, create a large road swale at an avalanche run out <br /> location to promote drainage in the spring, rip the hardened shale <br /> and sandstone which was excluded from the ripping task in the bid, <br /> and to complete minor miscellaneous earth moving tasks as directed <br /> by the Project Manager. <br /> The experience gained from this project will be useful in <br /> developing future road reclamation bids. Changes to future road <br /> bids, as discussed in the 1997 project recommendations section of <br /> this report, should be carefully considered in order to enhance the <br /> reclamation of the site. <br /> OTHER RECLAMATION RELATED ACTIVITIES <br /> Sutey Refuse Disposal Area <br /> Following the intense rain in July, it was noted that Ditches 1 and <br /> 8 at the Sutey Pile had failed. The velocity of the water in Ditch <br /> 1 exceeded the ability of the liner to remain intact. The high <br /> velocity flow rolled the liner into three to five feet diameter <br /> balls, and deposited them in the center of the channel, causing the <br /> ditch to widen in these areas. Subsequent observation of the ditch <br /> indicated that the high flow had eroded the ditch to bedrock in <br /> most segments. Therefore, relining of the ditch did not appear to <br /> be necessary to maintain channel stability. The balls of old liner <br /> were removed from the channel, but no further repair work was <br /> undertaken. <br /> Ditch 8 sustained significant breaching as the high velocity flow <br /> cut out of the lined channel and onto the adjacent, soft, shale- <br /> derived soils. Additional liner was procured, and was partially <br /> installed in late September. However, on the afternoon that the <br /> liner was being installed, an intense thunderstorm caused the newly <br /> installed liner to also fail. In early-October a second repair was <br /> undertaken. Given the two previous failures, it was apparent that <br /> the permit derived channel specifications were inadequate. <br /> Therefore, a dozer and backhoe were used to deepen the channel <br /> beyond the specified depth. Liner was added to the channel, and <br /> large logs and boulders were placed in and adjacent to the channel. <br /> The materials placed in the channel will tend to slow velocities of <br /> the water in the ditch. Logs were placed adjacent to the ditch in <br /> a chevron pattern pointing downhill. It is hoped that these <br /> materials will help keep the flow contained within the ditch. <br /> Small runoff events observed after the repair were contained in the <br /> ditch. However, it will not be known until after spring runoff <br /> whether the design will be capable of passing higher flows. <br /> Following a late-October snowstorm, the Sutey pile was reseeded <br /> using the Mine Site Seed Mix. This was undertaken due to the <br /> relatively poor stand of grasses established by the previous years <br /> 16 <br />
