North River Gravel Pit Weldon Construction <br /> 6. EXHIBIT E: Reclamation Plan <br /> 6.1. General Reclamation Plan <br /> Reclamation of previously mined and scheduled mining areas will occur within the 18.75 acres. <br /> Previously disturbed (by previous landowners), but not mined areas, will be allowed to continue the <br /> natural reclamation process which has been occurring successfully. <br /> Reclamation activities will be pursued for ineffective and unused areas as soon as operations allow. <br /> In these areas, backfilling will match surrounding topography and contours, but would not exceed <br /> 3:1 slope. <br /> Reclamation of the north pod and south pod will be pursued contemporaneously with mining and as <br /> operations allow. Backfilling and reshaping of pits will match surrounding topography and contours <br /> but would not exceed a 3:1 slope. <br /> 6.1.1. Topsoil Replacement <br /> After the mine is closed for production, backfilling and recontouring will occur. Pit and road slopes <br /> will generally be backfilled with subsoils, overburden, and unmined materials. <br /> Slopes will be left very rough; subsoils will have large divots and humps approximately 1-foot deep <br /> or tall. Recontouring to a rough texture helps trap broadcasted seeds and moisture, and helps to <br /> blend with the surrounding landscape. <br /> Stored topsoil and growth medium will be replaced evenly to a depth of 2-12 inches unless site <br /> conditions preclude this depth. Topsoil will also be left very rough. Soils will not be worked when <br /> wet to avoid mixing, loss of topsoil, and potential erosion issues. <br /> 6.1.2. Temporary Seed Mix <br /> Final seeding is best done in the late fall; therefore, if construction occurs in the summer, it may be <br /> desirable to apply a temporary seed mix to the area to help minimize erosion and provide some site <br /> stabilization. Temporary seed mixes are relatively inexpensive, and the large seeds germinate <br /> quickly. Two recommended varieties include: <br /> • Annual rye (Lolium multiflorum) <br /> • Regreen (a wheat and wheatgrass cross) <br /> Seeding can occur at a rate of around 20 lbs. per acre. <br /> 6.1.3. Long-Term/Permanent Seed Mix <br /> Seeding should occur in the late fall to avoid seeds from germinating in the summer or fall, and then <br /> either desiccating or freezing. Drill seeding could be utilized on more level terrain, but broadcast <br /> seeding will likely be needed on steeper slopes. Drill seeding will be the preferred method where <br /> equipment access is feasible; seed will be placed in direct contact with the soil at an average depth <br /> of 0.5 inch. For drill seeding applications, small seeds shall be packaged separately to allow for <br /> separate application. Small seeds will be planted no deeper than 0.25 inch or should be broadcasted. <br /> Broadcast seeding will be employed in areas where drill seeding is not possible. Seed will be <br /> uniformly applied over the disturbed areas with manually operated cyclone-bucket spreaders or <br /> mechanical spreaders. The following seed mix is a relatively"simple" mix, additional species may be <br /> added. <br /> 14 <br />
