• Additional protection for the fords will be provided to enhance the stability <br />of the running surface by salvaging the gravel on the existing roadbed that <br />will be removed and use it to create a new roadbase on the fords and the <br />slopes created to access the fords. Additional erosion protection for the <br />streambed will be provided by installing rip-rap keys at the upstream and <br />downstream edges of the ford. The keys will be a two foot wide by two <br />foot deep trench filled with one foot top size rip -rap. These rip rap keys <br />will ensure that the fords will not be washed out during high flow . <br />The bridge spanning East Salt Creek on the Operator's private property near <br />Highway 139 will not be removed. This bridge will protect the streambed yet allow <br />access to the hay fields located east of East Salt Creek. The bridge has been designed <br />to safely pass the flow from a 100 year storm event, see Appendix M. Removing the <br />bridge and regrading the area to install a dry ford would be environmentally detrimental <br />compared to leaving the bridge and approaches intact. <br />• 3.3.2 Backfillina and Grading -Upper Road <br />An extension of the road on the valley bottom was constructed up the side of the <br />canyon to access the coal outcrop. This portion of the road will be reclaimed utilizing a <br />track mounted backhoe, bulldozer, and other necessary equipment. Material will be <br />excavated from the berm and the area immediately downslope of the berm and placed <br />on the road near the toe of the cut slopes to eliminate the road and create a transitional <br />slope between the creek bottom and the steeper natural slopes. As the material is <br />placed at the toe, the dozer will grade it into two foot deep lifts and compact the <br />material. In those areas where ephemeral drainages cross the road, the material will be <br />excavated with a track mounted back hoe and moved into place with the dozer to <br />reconfigure the slope. <br />Drainages will then be reestablished and culverts removed. The premining <br />drainages crossing the road will be excavated to the original channel. Excavation to the <br />original channel which probably consisted of rock outcrop in these steep channels and <br />• Permit Renewal 3-7 08/03 <br />
