w • ', • III III III III IIII III MINING PLAN Exhibit "C" hereto, when considered in combination with Exhibit "C-1" (aerial photo), combines both the Mining Plan and Reclamation Plan Maps. The areas noted on Exhibit "C" are previously mined areas or areas presently being mined according to the following breakdown: Area 1 and Area 2 were both mined prior to the purchase of subject property by the applicants in 1967. At the time of the purchase of the subject property by the applicants, Area 4 had been approximately 1/2 mined and was completed by the applicant approximately 4 years ago. From approximately 1974 to November, 1977, the applicant worked the area indicated as Area 5 and is presently operating in the area noted as Area 6. The mining of Area 6 will be completed in approximately one year. Future extraction will then take place in segments of approximately five (5) acres, going North and then West on the parcel, the extraction of each parcel of approximately five acres taking approximately one and one-half (1-1/2) years. The mining is generally done in the following steps: (1). Topsoil and other soils covering the gravel deposit are removed by earthmoving equipment. In most cases removal of the soil is scheduled to precede gravel removal closely to minimize surface distur- bance. Some of the soil from mined areas is placed directly in its final location in previously mined areas according to the reclamation plan, thereby minimizing handling costs and speeding reclamation activities. (2). Subsequently, gravel is excavated and removed to the deepest level that can be mined economically. Gravel deposits usually lie in more or less uniform layers interspersed with pockets of clay, silt and other usable materials. The gravel deposit is removed with heavy earthmoving equipment. (3). The following step is reclamation of areas which have been disturbed by the excavation process in order to re-establish soil productivity where this is applicable and to make the area vailable for future land use. The reclamation process for previously worked areas takes place more or less simultaneously with the mining operation on current areas, i.e., mined areas are reclaimed while the next areas are being prepared for mining and mined. Using topsoil and other overburdened removed prior to the mining process, the ground surface in previously worked areas is shaped into final contours to re-establish land forms or made to utilize good growing soils to revegetate reclaimed areas where this is appropriate. Equipment used during the mining process is also used in reclama- tion operations along with ground shaping equipment and agricultural equipment used in revegetation. EXHIBIT D
