Section - 2.05.4 fences, etc.) until effective drainage can be reestablished. Any berms constructed to contain small drainage areas will be revegetated and left in place. The vegetative cover will help to stabilize the berms and over time the area on the uphill side of the berms will silt in completing the reclamation process. Regrading operations will be limited to existing disturbance areas and those immediately adjacent undisturbed areas necessary to provide for effective blending of regraded surfaces with the surrounding terrain. Fugitive dust emissions will be controlled during reclamation by periodic watering of roads and active redamadon areas. Soil materials will be sampled following replacement to verify suitability and will be stabilized by leaving the surface of the replaced soil in a roughened condition to minimize surface runoff and erosion and promote moisture infiltration and through application of straw or native hay mulch following seeding.

Any necessary application of soil supplements or fertilizer will be based on soil analysis results. Revegetadon success will be determined based on the results of revegetation monitoring. Revegetation monitoring for reclaimed areas will occur in the third ox fourth, ninth, and tenth year following permanent seeding. In general, ievegetation success will be evaluated based on the parameters of cover, production and diversity by comparing monitoring data from reclaimed areas and corresponding vegetation reference areas. The revegetation monitoring schedule, a description of monitoring and evaluation methods, and revegetation success criteria are detailed in the revegetation plan included in Exhibit 2.05-E6, Vegetation Information.
