Banks and Gesso, LLC <br />Sediment Pond Fines <br />Settling and sediment pond fines will be periodically cleaned out and the material will be <br />used as backfill. These pond areas will be backfilled and reclaimed as part of final <br />reclamation. <br />Final Grades (Reclaimed Slopes) <br />Backfilled areas and setback areas will be graded to approximate pre-mining contours <br />with a slight slope to the south-southeast to maintain pre-mining drainage patterns. <br />Pit slopes will be graded to comply with the Division's standards for pond slopes (i.e. no <br />steeper than 3:1 from 5 ft. above to 10 ft. below the pond water level and no steeper <br />than 2:1 below that}. Atypical 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 15`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 /> <br />Species <br />Variety - <br />PLS/acre <br />at 100% <br />% of species <br />in mixture - <br />PLS seeding rate per <br />species/acre <br />alkali sacaton Salado 1.5 30 0.45 <br />Switchgrass Blackwell 4 25 1.00 <br />Galleta Floret 11 15 1.65 <br />western <br />wheatgrass Arriba or <br />Barton 16 30 4.80 <br />The above seeding rates are based on drill seeding.
