western side of the lower dump area will be lined with 8" minimum rip-rap to help slow <br />storm flows and minimize sediment loading to the lower catchment basin. <br />Production/Process Stockpiles <br />For the next several field seasons, the lower staging area will serve as the main location <br />for product stockpiling and cnxshing/screening operations. The area is graded to drain <br />into the lower pit area and is large enough to facilitate a 5000 ton topsoil stockpile and up <br />to 20000 tons of product stockpiles. As mining progress to the north over time, process <br />areas and stockpiles will likely follow in the area immediately east of the working face as <br />waste rockpile lifts are leveled for mobile crusher, screening, and stockpile location. <br />Stacking conveyors maybe used to move finish rock material off of the limited space of <br />the upper bench azeas and down to the lower staging area where more storage space is <br />available. <br />Roadways within Affected Land Boundaries <br />County Road 228 enters the affected land on the southem end of the property and <br />traverses the affected land in the southern third and central portion of the affected land <br />area. This roadway will be maintained for public access at all times. Where the roadway <br />crosses Taylor Gulch, arip-rapped jeep trail crossing of the drainage will be maintained <br />to allow for 4WD vehicle access across the drainage channel. The crossing will have <br />three foot high (minimum) rip-rapped berms on either side of the crossing roadway to <br />insure sepazation of Taylor Gulch drainage from mine drainage. A permanent re-routing <br />of Forest Service Road 228 will is planned for the future, which will be engineered to <br />meet Forest Service specifications and approval prior to submittal to DMG as a permit <br />amendment. The timetable of mine development will allow for approximately five years <br />to mining prior to the need to relocate the existing roadway on the western slope above <br />the highwall area. <br />Within the active mining zone, roads will be limited to ramps and short term <br />(impermanent) switchback roads to various development levels that will change with <br />each season as pit development progresses to the north. Highwall development will be <br />gained from the southwestern end of the property with dozer trail installation along the <br />western edge of the affected land initiated from the southwest corner of the property. All <br />roads will be constructed at least 16 feet wide with "v" shaped ditches on either shoulder, <br />1.5 feet deep and 3 feet wide. All ditches will drain to the lower pit area. A waste rock <br />berm will be constructed along the western side of Taylor Gulch to insure that Taylor <br />Gulch drainage is separate from mine drainage. This berm be will constructed of waste <br />rock materials with dimensions no less than 4 feet high, 10 feet wide at the base, and <br />capped with no less than 6 inches of topsoil, seeded and mulched. <br />9 <br />
