All of the topsoil in the above listed stockpiles numbered A through K will be used in final <br />reclamation of the area east of 2700 Road. This includes the area of the overburden stockpile, <br />the haul road, the BB Detour Road and some other minor disturbance. All stockpiles have <br />slopes less than 3H:1V and have been seeded and mulched in the past. All have reasonable <br />vegetation cover and are not experiencing excessive erosion. The runoff from all stockpiles is <br />handled in designed sediment ponds. There is adequate topsoil in these piles to perform the <br />required placement in these areas according to the thicknesses shown on Map 2.05.4 -4. <br />8.1 Topsoil Storage on Prime Farmlands- Morgan Property <br />There are 107.96 acres of Prime Farmland on the Morgan property south of BB Road and west <br />of 2700 Road. The topsoil replacement thicknesses can be seen on Map 2.05.4 -4. In order to <br />satisfy the DRMS requirements related to Prime Farmland, the topsoil on the Morgan property <br />that is excavated after February 2008 will be salvaged in two lifts. Since the prime farmland <br />determination was not made until February 2008, portions of the Morgan property have been <br />retopsoiled with Bench 1 Substitute Subsoil and Mixed Topsoil. Map 2.04.9 -2 shows the topsoil <br />status of the Morgan property at the time. <br />Due to the complexity of the topsoil replacement plan on the Morgan property, a layout of the <br />different topsoil /subsoil areas based on their current status in reclamation has been <br />constructed. This is Map 2.05.4 -6. Additionally, this map contains calculations demonstrating <br />the topsoil balance for the entire 107.96 acres. The current volume of the existing stockpiles, <br />the volume of the existing stockpiles and the approximate volume of new stockpiles that have <br />not yet been constructed can also be seen on Map 2.05.4 -6. <br />A list of both existing and proposed stockpiles (as of June 2010) can be found in Table <br />2.05.4(2)(d) -2A. The location of all stockpiles in Table 2.05.4(2)(d) -2A can be seen on Map <br />2.05.4 -9 <br />As of June 2010, 51.7 acres of the Morgan property have been backfilled with Bench 1 material <br />as a substitute subsoil. See Attachment 2.05.4(2)(d) -1 for the Walsh Environmental Scientist <br />and Engineers Report on the sampling, testing and evaluation of the subsoil placement on the <br />Morgan property. <br />Revised September 2010 (PR 06) 2.05.4(2)(d) -16 <br />
