6.4.5 Exhibit E – Reclamation Plan <br /> <br />(a) Description of the Type of Reclamation <br />The site will be reclaimed to developed water resource and will construct three <br />additional water storage reservoirs Reservoir #2, Reservoir #4, and Reservoir <br />#2A which correspond to Cells 2, 4 and 2A respectively. Reservoir #2 shall have <br />a normal pool water surface area of approximately 32 acres. Reservoir #4 will <br />have a normal pool water surface area of approximately 24 acres. Reservoir 2A <br />will have a normal pool water surface area of 38.3 acres. Both reservoirs #2 and <br />#4 will be constructed with a compacted clay liner around the perimeter of the <br />mining highwall as shown in Figure 6.4.5 – 1 Typical Section, and Exhibit F, <br />Sheets 1-4. Reservoir 2A will be constructed with an embankment dam along the <br />north, east and west sides as shown in Exhibit F AM-2 Sheets 1 and 2. Detailed <br />engineering plans for the embankment dam have been submitted to the Office of <br />the State Engineer along with the application form. These documents are given <br />in Attachment A. The south portion of the perimeter of Cell 2A which is not part of <br />the embankment dam will be reclaimed by constructing a compacted clay liner to <br />the same specifications as Cells 2, and 4. Finally, a grass lined stormwater <br />diversion swale will be constructed around the perimeter of reservoir 2A to divert <br />stormwater from entering the Cell 2A reservoir. The design of the swale is given <br />in Exhibit E Attachment B Goose Haven Reservoir Complex Expansion Project <br />Cell 2A Hydrology Report. <br />Reclamation Earthwork/Compacted Clay Liner Construction <br />A summary table of reclamation earthwork volumes, areas and lengths is given <br />as Table 6.4.5-1. <br />Table 6.4.5-1.
