• slow down the runoff or to channel flows. Straw dikes will also be used where appropriate to control <br />runoff and promote vegetation. <br />Other Methods. If corrective measures described under "No Defined Channel" fail, further <br />observation will be necessary to develop additional measures. A combination of the first two <br />described methods or some variation will then be applied. Methods may include rock channels, <br />contour furrows, or laterals with rock or matting lined bottoms, V ditches made with a dozer or <br />motor grader, and methods described above to reestablish vegetation. <br />Head Cutting Stabilization. Head cutting will be controlled using several varying methods. If the <br />area is at a point that concentrates runoff, the area will be improved to accept the runoff. This would <br />include reshaping the channel and channel bottom, seeding, and covering the channel with erosion <br />matting or rock. In other areas, depending on the extent of erosion and time of year, disking and <br />seeding will be conducted as required. Straw bales, erosion matting and rock fill may also be used to <br />stabilize the area. Straw mulching and crimping will be considered as a further option. <br />• <br />SCC will submit to the Division by June 1 of each year, a copy of the map identifying the rill and <br />gully areas along with a rill and gully stabilization plan that briefly describes the problem at each <br />identified area and the proposed mitigative measures. The rill and gully stabilization plan will be <br />implemented by July 1 of each year and completed by November 1 or until weather conditions <br />restrict operations. <br />Revegetation Monitoring <br />During the life of mine operations, revegetation monitoring at the Seneca II mine has included both <br />qualitative and quantitative measurements. Qualitative evaluations were performed annually while <br />quantitative measurements were performed periodically. Periodic monitoring had previously been <br />carried out in select reclaimed units that were generally in year 2, 4, or 7 of development since initial <br />seeding. Mining and final reclamation have been completed at the Seneca II mine. Therefore. <br />monitoring efforts will shift away from quantitative revegetation monitoring and will concentrate on <br />• revegetation bond release sampling and evaluations for Phase II and Phase III bond release. <br />TR-50 13-25 08/09
