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 />soil surface. New soil material will be used in its place. This material will be tested <br />according to the original grid (1 hole per 2.5 acres on prime farmland, 1 hole per 5 <br />acres on non -prime farmland) to confirm its suitability. <br />4. If none of the above procedures satisfactorily mitigate a certain problem, the Division <br />will be notified and recommended actions will then be implemented. <br />WFC will periodically review the existing quality control program used with topsoil handling <br />activities at New Horizon Mine <br />In the event that a parameter average threshold value for a particular landowner is exceeded <br />based on the sample points for a given year, the outlier sample point will be further sampled as <br />an individual point of exceedance. The second phase and further sampling would be applied to <br />this outlier point to determine the area of influence. Once additional points were added, a new <br />average of the parameter will be calculated for the landowner in question. In the event that <br />remediation is determined to be necessary over an area to bring the parameter average to <br />within the threshold, topsoil that has already been sampled and demonstrated compliant will be <br />added to the outlier area. The outlier sample would then be sampled again following <br />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 <br />elevations and topography that are consistent with the approved reclamation plan and are <br />compatible with the post mining land use for the remediated area. <br />16.0 Resampling of Suitable Subsoil on Prime Farmland Soil Areas and Corresponding <br />Results <br />As is seen from the lab results of 6/27/08, eight samples were re -run based on saturation paste <br />extract for conductivity in the placed subsoil in prime farmland soils prior to February 2008. <br />Seven of these samples were acceptable, as seen in the included lab sheet, page Attachment <br />2.05.4(2)(d) -1 -14 . One sample, #32, still showed a high level of 7.33 mmhos /cm. Surrounding <br />Revised September 2010 (PR 06) 2.05.4(2)(d)47 <br />
