Sc~ton - 2.05.4 fences, etc.) until effective drainage can be reestablished. Any berms constructed to contain small drainage azeas will be revegetated and left in place. The vegetative cover will help to stabilize the berms and over time the azea on the uphill side of the berms will silt in completing the reclamation process. Regrading operations will be limited to existing disturbance azeas and those inrrnediately adjacent tmdisturbed azeas 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 reclamation 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 min;mi>e surface runoff and erosion and promote moisture infiltration and through application of straw or native hay mulch following seeding.

Revegetation success will be determined based on the results of revegetation monitoring. Revegetation monitoring for reclaimed areas will occur ut the third or fourth, ninth, and tenth year following perrrlanent seeding. In general, revegetation success Rill be evaluated based on the parameters of cover, production and diversity by comparing monitoring data from reclaittle d areas and corresponding vegetation reference areas. The revegetation monitoring schedule, a description of monitoring and evtluation methods, and revegetation success criteria arc detailed in [he revegetation plan included in Exhibit 2.05-E6, Vegetation Infom~:ttion.
