• P-2. In early 1986, there are an estimated 15 to 16 acres of disturb- ance in portions of the Limited Operation and Special Operation sites. It is expected that this situation will be satisfactorily corrected with all due diligence on approximately 8 to 9 acres in 1986. The balance of the area will largly be included in the active mining area identified as Phase 1, Exhibit C-2, and the work area immediately east of Phase 2. Reclamation will be com- pleted in most of this area by 1988. Phase 2 mining activity is expected to begin in late 1987. The depth of mining may range from 15 to 18' along the western bound- ary and portions of the northern boundary in this phase. Mining in an area will begin by removal of the gravel-laden top- soil material to a depth of 6 to 8" or more where it is found in small pockets. This material will be immediately redistributed on the land area of the just completed mining phase to the rear. Every effort will be made to avoid temporary stockpiling and the added cost of rehandling topsoil material. To accomplish the relocation of topsoil material, care will be exercised to avoid scraping and exposing more surface area than can be expected to be mined in any given year. Amore complete description of the reclamation practice is presented in the Reclamation Plan, Ex- hibit E. Mining will be done with a scraper for topsoil removal followed by a dozer and front-end loaders. A portable screen and crusher will be moved from time to time in order to remain centrally located near the working face of the embankment in each phase. As may be seen on the Mining Plan Map, Exhibit C-2, the phased areas surround a deleted area that represents a shallow Swale and natural drainagewa}'. Mining activity on the surrounding phases will carefully maintain the natural drainageway by the construction of the temporary haul road around the upper perim- eter in a manner to serve as a barrier forming retention ponds during the course of mining. In addition all excavation will be halted at a depth that will maintain a slight positive flow toward the upper reaches of the Swale upon final reclamation. Excavation in Phases 4 & 5, however, will tend to create the natural drainage direction to the east, thus entering the drain- ageway lower in the Swale. The depth of the overburden and gravel ladened topsoil material is 20" deep in portions of Phases 4 b 5. Therefore, an adequate supply of excess material will be maintained in an orderly stockpile on part of the Phase 5 area for final reclamation. The life of the mine is estimated to range from 7 to 10 years. Exhibit E - Reclamation Plan The reclamation plan is designed to reduce the financial exposure to an amount necessary to restore 8 to 10 acres including the area of temporary haul roads.
