Surface snd subsurface soil material must be saved and stockpiled during [lie mining process if reclamation ie to be accomplished on this project. Tlie quantity and quality of material is..dependant on the soil types currently covering the site. Two main eofl types exist on the forty acre parcel - soil map unit 20, Derrick very gravelly loam, 0 to 3 percent slopes, and soil map unit 70, Space City loam send 0 to 6 percent elopes. In general the Derrick soil occupies tl~e northwest portion of the parcel and the Space City soil occupies the southeast portion. A soils map and copies of soil descriptions are included with tiiia report. Tlie surface soil material that is very important to the reclamation process is approximately 10 inches deep in the Derrick soil and up to 18 inches deep in the Space City soils. Both soils will have visible calcium carbonate layers at or near these depths. The limy profiles should not be mixed with the topsoil and should be used as the separation zone between topsoil and subsoil materials. To complicate the process further' the material from the two main soil types should be stockpiled separately since the soils are so different. Tlie gravelly loam of the Derrick series may be reclaimed differently than the loamy sands of the Space City series. Four major stockpiles will be necessary to maintain the separation of material: one each for the topsoil from the two soils and one each for the subsoil materials to be saved. The stockpiles must be located far enough from the mine pit a[ permanent locations to be stabilized until future use. The shape and size of the piles will be determined by the equipment used to accumulate and stabilize the material. Tl~e volume shall be adequate to apply a uniform layer of soil material to a thickness of 18 inches over the entire disturbed area for the reclamation purposes. Stability of the stockpiles shall be obtained by seeding with adapted grasses at least once a year. The seed mixtures to be used will be addressed later in [hl.s report. The seeding dates shall be June 15th to June 25th or tiie last week of October of each year. Seeded stockpiles will be maintained until needed for reclamation without adding material or disturbing with heavy equipment. .:" ' INAL GRADING As the mining progressese, systematic reclamation should be accomplished. Clue final grade is very important to the success of the process. Since the mining is to proceed to the southwest, the aspect will result in a relatively trot, dry site. ~I~o make the most of the scant precipitation, all slopes must be fairly Elat - no steeper • than ~ to 1 with a gentler slope preferred.
