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

<br />Soil samples will be analyzed for the parameters of pH, acid-base potential, saturation percent,
<br />electrical conductivity, sodium adsorption ratio, selenium, boron, texture, nitrogen, phosphottrs, and
<br />potassium Any necessary application of soil supplements or fenilizer will be based on soil analysis
<br />results.
<br />Revegetation success will be determined based on the resulu of revegetation monitoring.
<br />Revegetation monitoring for reclaimed areas will occur in the third or fourth, ninth, and tenth yEaz
<br />following permanent seeding. In general, revegetation success will be evaluated based on the
<br />parameters of cover, production and diversity by comparing monitoring data from reclaimed areas
<br />and corresponding vegetation reference areas. The revegetation monitoring schedule, a description of
<br />monitoring and evaluation methods, and revegetation success criteria are detailed in the revegetation
<br />plan included in Exhibit 2.05-E6, Vegetauon Infomration.
<br />Muting-related surface disturbance for the Somerset, Sanborn Leek, and Ells Creek Mines is generally
<br />associated with the individual underground operations and mayor may not be contiguous with other
<br />surface disturbance. Interim reclamation of individual areas may occur while active operationu
