4. Topsoil and Overburden Handling <br />A significant portion of the 5.0 acres was disturbed pre -law, and no topsoil was salvage from this <br />area. To make up for this deficit in growth material, manure will be added to the fines produced <br />from screening at a rate of 20 tons per acre. <br />Most of the deposit to be recovered under this permit is 20 -30 -foot -thick Quaternary dune sands <br />and gravels. There will be stockpiles of recoverable topsoil on the site, approximately 1300 CY. In <br />the undisturbed portions of the site, available topsoil will be stripped for use in reclamation and <br />stored in stockpiles. Topsoil and overburden in the undisturbed areas ranges from 6 to 8 inches <br />thick. This should generate roughly 2000 CY of topsoil. Topsoil and overburden will be stored for <br />reclamation in stockpiles (Map C-2) during active mining. Any topsoil or overburden storage berm <br />will be vegetated within 180 days of completion. Table D-3 shows the topsoil stripping that will <br />take place at each step of the mining operations, as shown on Maps C- I and C-2. <br />Table 0-3 Topsoil Stripping Areas <br />AOl Area I Topsoil Present <br />Full Min <br />Remaining dunes <br />5. Water Handling <br />1.3 Acres i Y <br />Water handling at the Ayers Pit will be minimal during the remainder of the mine life. Runoff will <br />be managed in activity areas to prevent the discharge of sediment into tl}e local watershed. Map F <br />shows how the final shape and slopes and water drainage directions of the reclaimed mine area. The <br />mining and reclamation plans feature final topography dimensions with more than enough depth to <br />allow full containment of the 100 YR event (4.41 inches). <br />6. Schedule of Operations <br />The Ayers Pit will process material sporadically with the ability to do so 6 days per week (Monday - <br />Saturday) on a year-round basis. Material processing will occur from 7AM-6PM with a 1 hour <br />warm up period prior if necessary. Repairs to equipment will typically take place during daylight <br />Ayers Pit December 2016 D-3 <br />
