0 <br />0 <br />Soil suitability criteria for all non prime farmland areas west of 2700 Road are addressed in <br />Table 2.05.4(2)(d) -1 B. These areas will be stripped and replaced in a single lift of mixed topsoil. <br />Depth measurements shall be taken at the same locations as the original sample sites. <br />Replacement depth information shall include thickness of Mixed. The topsoil salvage and <br />replacement depth information will be kept on file at the mine office and will be submitted with <br />the ° Annual Topsoil Balance /Spoil Quality Report Topsoil recovery depths will be adjusted if <br />warranted by the site conditions. Sample frequency is as shown in the table for each material <br />type: <br />15.0 Topsoil Remediation Plans <br />In the event that any one spoil sample result exceeds the limits, WFC will implement the topsoil <br />remediation plan below. <br />If one or more parameters fall within the unsuitable range at a given grid point, a three -part <br />Mitigation plan will be implemented. <br />1. The area around a suspect hole will be sampled on a closer spacing interval in order <br />to better define the lateral extent and variability of the unsuitable material. This <br />sampling will be called the 2 nd Phase sampling and the interval is one hole per 50 feet <br />distance around the bad point in all directions for prime farmland, and one hole per <br />100 feet distance around the bad point in all directions for reclaimed irrigated <br />pastureland and dryland pasture. <br />2. If 2 nd phase sampling shows an exceedence, follow -up sampling will take place to <br />delineate the area of exceedence. Delineated areas of exceedance that are larger <br />than 0.1 acres for prime farmland, 0.25 acres for reclaimed irrigated pastureland or <br />0.50 acres for dryland pasture will be remediated. <br />3. For remediation, any area identified above which excceds the acreages stipulated <br />above for unsuitable topsoil material will be placed at least eight feet below the final <br />Revised PR 06 June 10 2.05.4(2)(d) -46 <br />
