A typical cross - section of these slopes is shown on Exhibit C -3. <br />Revegetation (Maintenance and Monitoring) <br />After topsoil has been placed in an area to be reclaimed, the surface will be plowed prior <br />to seeding. This will occur on both flat and sloping surfaces. Planting will take place <br />between November 1 and April 30 <br />Flat and gently sloping areas will be drill seeded and pit slopes will be broadcast seeded. <br />The table below outlines the species and seeding rates to be used for reclamation, <br />based on consultation with the NRCS. Refer to Attachment A — NRCS Reclamation <br />Plan Letter for more information. <br />Table E -1: Seed Mix <br />Paul Banks and Associates, LLC <br />The above seeding rates are based on drill seeding. These rates will be doubled if <br />seeds are broadcast. <br />Fertilizer will be applied at the time of seeding at the rate of forty pounds per acre of both <br />elemental nitrogen (N) and phosphoric acid (P205), if required. This will be incorporated <br />into the soil with a disk or harrow implement. Mulch such as grass hay or cereal grain <br />straw will also be applied to the reseeded area at the rate of 4,000 pounds of mulch per <br />acre. <br />St. Barbara Sand and Gravel Mine 10031 <br />Pete Lien & Sons, Inc. 15 June 15, 2011 <br />
