2. If 2nd phase sampling shows an exceedence, follow-up sampling will take place to delineate the <br />area of exceedence. Delineated areas of exceedance that are larger than 0.1 acres for prime <br />farmland, 0.25 acres for reclaimed irrigated pastureland or 0.50 acres for dryland pasture will be <br />remediated. <br />3. For remediation, any area identified above which exceeds the acreages stipulated above for <br />unsuitable topsoil material will be placed at least eight feet below the final soil surface. New soil <br />material will be used in its place. This material will be tested according to the original grid (1 hole <br />per 2.5 acres on prime farmland, 1 hole per 5 acres on non -prime farmland) to confirm its <br />suitability. <br />4. If none of the above procedures satisfactorily mitigate a certain problem, the Division will be <br />notified and recommended actions will then be implemented. <br />WFC will periodically reviewthe existing quality control program used with topsoil handling activities at New <br />Horizon Mine. <br />In the event that a parameter average threshold value for a particular landowner is exceeded based on the <br />sample points for a given year, the outlier sample point will be further sampled as an individual point of <br />exceedance. The second phase and further sampling would be applied to this outlier point to determine <br />the area of influence. Once additional points were added, a new average of the parameter will be <br />calculated for the landowner in question. In the event that remediation is determined to be necessary over <br />an area to bring the parameter average to within the threshold, topsoil that has already been sampled and <br />demonstrated compliant will be added to the outlier area. The outlier sample would then be sampled again <br />following remediation to determine the success of remediation. <br />Any remedial backfilling and/or burial will be completed in a manner that results in final surface elevations <br />and topography that are consistent with the approved reclamation plan and are compatible with the post <br />mining land use for the remediated area. <br />16.0 Literature Cited <br />August 2013 (PR -08) 2.05.4(2)(d)-30 <br />
