Introduction <br />Section 2.05.4(2)(d) <br />Topsoil Redistribution <br />This section outlines WFC's plan for removal, storage and redistribution of topsoil, <br />subsoils and other material, to meet the requirement of Section 2.05.3(5), 2.05.4(2)(d) <br />and 4.06 for the New Horizon North (NHN) Mine permit application. The plan addresses <br />those reclamation activities that are conducted during and immediately after backfilling <br />and grading (Section 2.05.4(2)(c), but prior to revegetation (Section 2.05.4(2)(e)). The <br />objectives of the plan are to reconstruct plant growth and aquifer mediums that are <br />consistent with the post- mining land uses. The plan objectives are achieved by insuring <br />that a sufficient thickness of suitable backfilled weathered overburden material is <br />replaced as rooting medium subsoil over the unoxidized overburden and below the <br />respread topsoil. On average there will be approximately three to four feet of suitable <br />weathered "spoil material, including the available topsoil, that will be replaced onto all <br />regraded spoil areas prior to the commencement of revegetation activities. The weathered <br />overburden material which will be respread on top of the regraded spoil material and <br />prior to topsoil replacement is called "Bench 1 Surface Spoil or free dig zone material" in <br />the existing NH2 Mine Permit and will be called the same thing as this practice applies to <br />the NHN Mine. <br />The plan presents an account of the plant growth material and aquifer medium <br />requirements based upon current and projected disturbance acreage and plant growth <br />material and aquifer medium availability based on detailed baseline topsoil inventory <br />mapping and overburden assessments. The plan also describes the procedural aspects of <br />removal, storage, redistribution, and testing of topsoil materials. <br />Overburden/ Spoil Handling Plan <br />New Horizon North Mine Overburden and Interburden Characteristics <br />Section 2.05.4(2)(d) Page 1 January 2012 <br />
