14.0 Topsoil Suitability Criteria and Testing Plan for Reclaimed Soils <br />Prior to distribution of topsoil, all graded mined areas (on which topsoil is to be applied) will be sampled <br />to confirm spoil suitability (see Regraded Spoil Monitoring Plan in subsection 4.0 of this section for more <br />details). The density and physical characteristics of the replaced topsoil and upper spoil will be observed. <br />The suitability criteria is required to ensure that no poor topsoil or subsoil is placed near the surface of any <br />reclaimed area and that prime farmlands are restored to strict standards for high productivity. <br />Soil suitability criteria for all non prime farmland areas west of 2700 Road are addressed in Table <br />2.05.4(2)(d)-1. Soil suitability for prime farmlands is addressed is Section 2.06.6. <br />Depth measurements shall be taken at the same locations as the original sample sites. The topsoil salvage <br />and replacement depth information will be kept on file at the mine office and will be submitted with the <br />Annual Topsoil Balance/Spoil Quality Report to DRMS. Topsoil recovery depths will be adjusted if <br />warranted by the site conditions. Sample frequency is as shown in the table for each material type. <br />15.0 Topsoil Remediation Plans <br />In the event that any one soil sample result exceeds the limits, WFC will implement the topsoil remediation <br />plan below. <br />If one or more parameters fall within the unsuitable range at a given grid point, a three-part mitigation plan <br />will be implemented. <br />1. The area around a suspect hole will be sampled on a closer spacing interval in order to better <br />define the lateral extent and variability of the unsuitable material. This sampling will be called the <br />2nd Phase sampling and the interval is one hole per 50 feet distance around the bad point in all <br />directions for prime farmland, and one hole per 100 feet distance around the bad point in all <br />directions for reclaimed irrigated pastureland and dryland pasture. <br />August 2013 (PR -08) 2.05.4(2)(d)-29 <br />
