1 1 1 EXHIBIT D t MINING PLAN Connell Resources, Inc. (herein Connell) currently has sand and gravel mining, an asphalt batch plan[, and headquarters just north of the proposed Wellington Downs permit site (known as the Stute Pit, M-81-007). They have been operating the Stute Pit since 1990. Connell supplies local, county, ' and state governments, as well private industry with aggregate and asphalt. Connell has just about exhausted the sand and gravel reserves and is in the process of reclaiming the site. Therefore, they must relocate to the Wellington Downs deposit. 1 The proposed permit azea for the Wellington Downs operation is 109.5 acres, of which 93.1 acres will be disturbed by mining. ' The Wellington Downs deposit has been drilled and contains an estimated 1.2 million cubic yazds of sand and gravel. The deposit has 4.5 average depth of overburden and a 10 foot average depth ' of sand and gravel. The overburden will be removed and stockpiled for reclamation. About ] 0% of the deposit will be unmazketable fines and used along with the topsoil and overburden for ' reclamation. Phasin ' Currently Connell processes 200,000 and 250,000 tons of aggregate per yeaz. They expect to keep this same rate of production at the Wellington Downs site. They will mine between 10 to 15 acres ' a yeaz. At this rate of mining they expect to mine and reclaim the site in 8 to 10 years. The operation will be mined in phases to limit the area of disturbance at any one time (see Exhibit ' C). The phases depicted in Exhibit C aze used to indicate the direction of mining. These phases are neither representative of the maximum area of disturbance nor do they limit disturbance to a particulaz phase. In Phase 1 Connell will mine the southeast end of the deposit. Mining will proceed ' from west to east. A portion of Phase 1 will be backfilled and topsoiled and Connell will locate their stationary equipment here. ' Phase 2 of the operation will consist of mining a 100 foot wide strip around the perimeter of the property. This will allow Connell can install a aquitazd boundary around the entire property and ' obtain mazketable aggregate in the process. The aquitazd boundary will minimize the groundwater inflow into the pit and limit the potential effects of dry mining on surrounding well owners. Topsoil and overburden will be temporarily stockpiled along the boundary of Phase 2. As the perimeter is sealed stockpiled overburden and topsoil will be used to backfill portions of Phase 2 that are not included in the final reclamation plan.
