Chapter II <br /> <br />In recent years, winter access has been maintained to Mine Portals #1 and #2, but has <br />not been maintained to Mine Portals #3, #4 and #5, given their current idle status. <br />Other than snow removal, maintenance of the roads is generally done after snowmelt <br />and before snowfall. <br />Spring/Summer Maintenance. <br />Road maintenance after the snow melts will include repair of ditches, clean-out and <br />repair of culverts and cross drainage structures, grading of the road, re-establishment <br />of water bars and berms, repair of tilling and erosion channels. <br />After storm events, road ditches and culverts will be inspected to identify areas of storm <br />damage, filled-in ditches or plugged culverts. Repair and clean-out will be done as <br />expeditiously as possible. <br />Material cleaned from ditches, catchment basins, culvert installation repair, and B.A.T. <br />ponds on the roads will be used as a growth medium for vegetation, for berm material, <br />or to cover trash. <br />• Culverts. <br />Culverts will be inspected to determine whether repair or replacment is necessary. <br />Replacement of culverts will be judged necessary when the culvert has been damaged <br />so as to fail to pass flows, or when the culvert has been worn and rusted to the point <br />that leakage endangers the integrity of the road. On light use roads, rolling dips may <br />be installed in place of rusted culverts. <br />Ditches. <br />During the spring, and as necessary after storm events, the ditches will be dragged to <br />clean them of debris and sediment. <br />Catchment Basins. <br />Maintenance of the basins will usually be done with a trackhoe and/or front end loader. <br />Sediment will be cleaned from the basins on an as necessary basis. <br />B.A.T. Ponds -Off Road. <br />• For maintenance of ponds which are in areas difficult to access, such as below the <br />downslopes of Road D, 110+00 to 100+00, a trackhoe will be used in preference to <br />equipment such as dragline/trucks, which would require building a road. Sediment <br />removed from the ponds will be deposited at the site, vegetated and mulched. <br />19 <br />Revised 6/92 <br />
