for more than one growing season and will be constructed with a minimum 2: I slope. Re rading and Shaning 13 The pit slopes will be backfilled from their mined condition and "mined-through" location, to an undulating shoreline with rounded corners. The backfill will be placed in 3:1 slopes leading to the reservoir/pit bottom, prior to topsoil placement, using a mixture of shale from the pit floor and overburden, depending on reclamation detail at that point.. Approximately 1 ft. (12 inches) of topsoil will be placed on all disturbed level areas around the reservoir pond, and on a113:1 slopes, both above and slightly below the expected high water-line, for the filled reservoir. Contour furrows will be established on the shoreline slopes to reduce erosion and encourage stable plant growth. Topsoil will be smoothed out along the shoreline and furrowed as seedbed preparation for successful native grass seeding and growth. Tonsoil Replacement Topsoil replacement to a thickness of approximately 1 fr. will occur following sloping and regrading of all disturbed surface areas that will be exposed above and 3 feet below the high- water level of the filled reservoirs within the permit area and after placement of PVC liner in Section AA portions.. Topsoil spread asplant-growth medium will be spread over ground that has been smoothed and readied for topsoil replacement. Due to the loose and permeable nature of the sand and gravel over the slightly disturbed pit edges ripping or scarifying of the disturbed ground will not be required. Disking of the topsoil maybe required due to compaction while in storage; and this will be performed prior to seeding, if necessary. Reveeetation Soil Amendments Replaced topsoil will be subjected to agricultural testing for the major plant nutrients (nitrogen, phosphorus, and potassium) prior to revegetation to assess the need for fertilizer. If test results show a need for amendments, a fertilizer with the appropriate ratio of major nutrients will be selected and applied prior to reseeding. NRCS soil fertilizer recommendations, if any, will be followed. Mulch In order to minimize impacts from wind and water erosion and to protect newly revegetated areas, a native hay or straw mulch is proposed. Mulch will be applied at a rate of 2000 pounds/acre and crimped or disked into the topsoil surface. Only mulch certified as weed and pest free will be employed. Mulch will not be used in areas along the pond margins where it may become wet or molded. 2RR app CDMG 112
