• TAB 27 <br />MINESOIL RECONSTRUCTION <br />Introduction <br />This chapter outlines Seneca Coel Company's (SCC's) plan for reconstructing mined-lend <br />soils end spoil at the Yoest Nine. The plan addresses those reclamation activities that <br />ere conducted during and immediately after backfilling and grading (Tab 20), but prior to <br />revegetetion (Tab 22). The objectives of the plan ere to reconstruct plant growth end <br />aquifer mediums that ere capable of supporting the postmining lend uses. The plan <br />objectives ere achieved by insuring a sufficient thickness of suitable spoil is replaced <br />in the pit bottom and a minimum of four feet of suitable plant growth materiel, including <br />soil, exists on the surface of graded lends prior to the commencement of revegetetion <br />activities. The plan presents en account of the plant growth material and aquifer medium <br />requirements based upon current and projected disturbance areas end plant growth materiel <br />and aquifer medium availability based on soil depth mapping end overburden assessments. <br />• The plan also describes the procedural aspects of removal, storage, redistribution, and <br />testing of soil materiels. <br />Overburden/SOOiI Handling Plen <br />The followi n9 overburden/spoil handling plan was developed to ensure a minimum of three <br />feet of suitable plant growth material exists on graded lands pri of to the commencement of <br />soiling activities. The plan is based upon the overburden assessment information <br />previously discussed in Tab 6. <br />Overburden and Underbu rden Characteristics. Overburden end underburden characteristics <br />ere presented in Tab 6, Geology and Overburden Assessment. Overburden suitability is very <br />similar to the Nedge and Nolf Creek mining areas for SCC's Seneca II end II-N Mines. The <br />Seneca II Mine is located 4 miles northeast of the Yoest permit area while the Seneca 11-N <br /> Mine is located 3.5 miles west. Approximately 78 percent of the overburden material <br /> within the Nadge and Wolf Creek rec overy areas is classified es suitable for root grouch <br /> and aquifer medi um material (Tab 6, Appendix 6-3; Tab b, Table 5, and Exhibit 6-4). All <br /> overburden end underburden strata had suitable values for salinity, selenium, lead, <br /> cadmium, nickel, and copper. <br />1 Revised 03/01/95 <br />
