applied to this area. This will not be necessary with the change in road access to <br />the north of the currently disturbed zone. <br />The roadway scheduled for removal east of the affected land boundary includes a <br />70' portion of roadway accessing the upper road cut scheduled for reclamation. <br />The roadway azea will be filled to minimize sheet wash from the general azea <br />towards Taylor Gulch. The azea will be backfilled and compacted between one <br />and six feet, topsoil applied at a thickness of 12", and seeded along with former <br />road cut. The sectioa of roadway that will be reclaimed will ripped via bulldozer <br />prior to backfilling in order key in fill material prior to backfilling. <br />X44 The writer is not sure of Division's reference to "containment berm along the <br />~~ horizontal runs of the mine. If the reference is made to the sediment control <br />berm, it is planned to place a sediment control berm along the entire length of the <br />west side of Taylor Gulch as mining progresses to the north. This sediment <br />control berm will be constructed of waste rock material and will be topsoiled and <br />seeded with approved permanent seed mix. The intent of the sediment control <br />berm is to keep Taylor Gulch drainage sepazate from the mining azea west and <br />immediately adjacent to Taylor Gulch, and to keep waste rock piles or topsoil <br />stockpile materials from washing into Taylor Gulch drainage channels during <br />storm events or heavy snow melt. The sediment control structure will be a <br />permanent structure that will remain after mining cessation to insure separation of <br />drainage patterns. <br />yY. A typical cross section of reclaimed mine benches is included with this mailing <br />~- depicting ditches, berms, and contour furrowing. <br />~2: All sites will be ripped with a lazge (D-9 size) bulldozer prior to topsoil <br />~3 application. This technique will be used on all benches, staging areas, slopes, and <br />final graded areas prior to top soil application. Dozer ripping will be to a depth of <br />2' minimum or more if possible. Mine bench ripping may be minimal due to rock <br />conditions encountered especially in the lower reaches of the bench system. <br />y3'General timing of seed application will be late winter/early spring (May 1 through <br />~~ Junel) or fall application (late September). Seeding method will be broadcast <br />with increased application rates to compensate for surface application. Contour <br />furrowing techniques also help to mitigate surface applications of seed mix due to <br />course surface textures left by technique. <br />~5' ~Y. 'T'he waste rock bean will be covered with topsoil and re-vegetated with <br />permanent seed mix. The structure will left as a permanent structure to help <br />control drainage patterns for Long term run-off control after cessation of mining. <br />u t 4~fhe footprint of the lower pit at the end of mining is yet to be determined, based <br />l tP ~ on lowest mining elevation allowed limited by final highwall rock stability <br />analysis results. Footwall rock competency will determine the configuration and <br />
