EXHIBIT D MINING PLAN Connell Resources, Inc. (herein Connell) currently has sand and gravel mining, an asphalt batch plant, and headquarters immediately west of the proposed Timnath Connell Pit permit site. Connell supplies local, county, and state governments, as well private industry with aggregate and asphalt. Connell has almost completed mining the sand and gravel reserves and is in the process of reclaiming the Wellington Downs (Permit No. M-95-035) site. The proposed permit will provide future reserves for continuation of Connell's operations. The proposed permit area for the Timnath Connell Pit operation is 157.58 acres, of which 144.56 acres will be disturbed in phases by mining. The remainder of the property will be used for locating asphalt processing facilities. The asphalt facilities are not a part of the permit because they are not totally dependent on the sand and gravel mining of this proposed site and are located outside the proposed permit boundary. They will remain in place after mining and reclamation is completed on the proposed permit and will continue to operate. The Timnath Connell site has been drilled and testing has verified that there are commercially marketable sand and gravel deposits on the property. The deposit has 5.0 foot average depth of overburden and a l 1 foot average depth of sand and gravel. The overburden will be removed and stockpiled for reclamation. Phasine Currently Connell processes approximately 400,000 tons of aggregate per year. 'they expect to keep this same rate of production at the Timnath Connell Pit site. They will mine between 10 to 20 acres a year. 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 a[ any one time (see Exhibit C). The phases depicted in Exhibit C are 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 particular phase. Phase I will be mined and the wash plant equipment will be located here until Phase 3. in Phase 2 Connell will mine the perimeter of the property in a strip ranging from 100 feet to 200 feet wide. Well points will be constructed and dewatering done during this phase as described in Exhibit G. The outside of the perimeter will be backfilled and lined with impermeable material as the operation progresses. This will disconnect dewatering impacts from the alluvial aquifer. The mini+~g will start at tl~e north end ~f the deposit where future stockpiles will be placed. l his area will then be backfilled and reclaimed to allow the siting of a wash plant. Approximately 20 acres will be needed for all processing and stockpiling operations. The impermeable boundary will ntinitnize the groundwater inflow into the pit and limit the potential effects of dry mining on surrounding well owners.
