• covered with erosion matting and seeded, orrip-rapped with energy dissipating rocks. The method <br />used will of course depend on site conditions. Continued observations will be made of this area <br />for problems or necessary maintenance <br />No Defined Channel. On slopes where no swale or defined channel exists, a number of <br />operations will be performed, depending on the extent of the erosion. The area will be disced and <br />retopsoiled if needed. The site will then be mulched and crimped or erosion matting will be placed <br />on the area, depending again on site specifics. Reseeding will then take place. <br />In addition to the above, contour furrows in and above the erosion area may be constructed to trap <br />and slow down the runoff. Straw dikes will also be used where appropriate to control runoff and <br />promote revegetation. <br />Other Methods. If corrective measures described under No Defined Channel fail, WFC proposes <br />to observe and reevaluate the situation. A combination of the first two methods described or some <br />variation therein will be applied. Methods such as, but not limited to rock channels, contour furrows <br />or laterals with rack or matting bottoms, V ditches made with the dozer or motor grader, and <br />. methods described above to reestablish vegetation. <br />Head Cutting Stabilization. Head cutting will be controlled by a number of methods. If the area <br />is at a point that concentrates runoff, the area will be improved to accept this runoff. This would <br />include reshaping the channel and channel bottom, covering with erosion matting, seeding, or <br />rocking. <br />In other areas, depending on the extent of erosion and time of year, the area will be disced, <br />mulched and seeded as needed. Straw bates, erosion matting, or rock fill may also be used to <br />stabilize the area. <br />Weed and Pest Control Plan -All Areas <br />A number of noxious weeds occur in the region surrounding the New Horizon Mine area. <br />Specifically, the following noxious weeds (as listed in Section V, CDMG Guideline for the <br />• (Revised zoo) Attachment 2.05.4(2)(e)-28 <br />
