Following completion of all construction activities requiring access by vehicular traffic, a large <br /> berm shall be constructed at the junction of the Huntsman Ridge Road with the Mine 4 Bench. <br /> PROJECT MANGER will mark the location of the berm in the field. The minimum dimensions of <br /> the berm will be five feet (5) in height, one foot (1') wide at the crest, twenty one feet (21') wide <br /> at the base, and approximately twenty feet (20') long (estimated width of the road); side slopes <br /> will be no steeper than 2.5 H : 1 V. <br /> All Road Segments <br /> Ripping must occur immediately prior to initiating revegetation procedures. All ripped road <br /> segments must be protected from vehicular traffic. PROJECT MANAGER will lock the site <br /> access gates. However, should vehicles travel across ripped roadways, CONTRACTOR may <br /> be directed to re-rip the affected road(s). <br /> In order to protect the ripped road segments from compaction, CONTRACTOR will place bales <br /> to be used for mulch along the road margins prior to ripping. Following ripping, only ONE trip <br /> with a three quarter (3/4) ton or lighter pick up truck and single axle trailer will be permitted <br /> across the reclaimed road segment. Should this crossing result in rut development or <br /> compaction which, in the opinion of the PROJECT MANAGER, is excessive, CONTRACTOR <br /> shall re-rip, re-seed and re-mulch the segment(s) of concern. Additional access shall only be by <br /> low ground pressure all terrain vehicle. <br /> Mine 1 /2 Training Center <br /> Map 4, Hydrologic Structures, depicts the location of the Mine 1 /2 Training Center. Earthen <br /> materials have been end-dumped near the eastern margin of this area. These materials will be <br /> graded out across this approximately three quarter(3/4) acre area. Following placement of <br /> these materials, topsoil may be applied to the ground surface. Up to two hundred cubic yards <br /> (200 yd3) of topsoil materials, located within six hundred feet (600 ft.) of the area, will be evenly <br /> distributed across the area. <br /> Following distribution of the earthen materials and topsoil, the area will be mulched and scarified <br /> as follows: <br /> The excavated embankment cut surface shall be severely roughened following completion of the <br /> earth work to the specifications using a trackhoe or similar piece of equipment in the following <br /> manner: <br /> - Two (2) tons of certified weed free mulch shall be applied to the surface. Mulch shall <br /> be provided by CONTRACTOR, and shall conform to Section 20.2 of the Revegetation <br /> Specifications, attached. All mulch shall be certified as noxious weed free or noxious <br /> weed seed free by any authorized State or County Officer. Documentation of <br /> certification shall be provided to the PROJECT MANAGER prior to application of <br /> mulch. The mulch shall be evenly distributed over the surface. Surface roughening will <br /> occur simultaneously with distribution of the weed free mulch in order to prevent loss of <br /> the mulch due to wind. <br /> - Roughening, or scarification of the surface by using a trackhoe bucket or similar <br /> piece of equipment to create numerous gouges in the cut slope will follow mulching. <br /> Gouge or pull the surface and mulch toward the machine in a manner such that no <br /> less than twelve inches (12") of vertical relief is created. These gouges shall be <br /> sufficiently close so that no more than eighteen inches (18") exists between the crest <br /> of one gouge and the crest of an adjacent gouge, in any direction. <br /> 12 <br />
