EXHIBIT "D" <br />MINING PLAN <br />6.4.4 The Mining Plan for the Blue Grass Gravel Pit (East and West pits) is as follows: <br />(a) Description of the methods of mining in each stage of the operation as related to any <br />surface disturbance on affected lands: <br />Mining methods will be consistent throughout the life of this mining operation. The post mining <br />reclamation plan is developed water resource for, both pit areas. The topsail will be saved for <br />use during reclamation. Overburden will not be sold as product until it is determined by the <br />Operator that enough overburden has been stockpiled and saved for reclamation use and for the <br />construction of the perimeter slurry wall and earthen dam. This will be an open pit mining <br />operation. The method of mining the sand and gravel will be to construct slurry walls, dewater <br />the mining area and "dry mine" the raw materials from the pits. (The ezcrxvated material will <br />still have some level of moisture and will require augmentation for evaporative losses.) <br />Primarily, scraper(s), front end loader(s) and/or excavator(s) will remove the aggregate. <br />Material may then immediately be truck hauled to the crushing and screening plant, or stored in <br />the pit for later processing. <br />Mining will be done in phases. Mining will begin in the East Pit, called Stage 1, Phase 1 at the <br />south end of the East Pit (east permit area) and will move in a general direction to the northwest <br />corner of the East Pit. All mining will be carried out in the planned phases as delineated on the <br />Mining Plan Map. After each phase is completely excavated, the operator will move into the <br />next phase as shown on the mining plan map (please see the enclosed map, Exhibit "C"). This <br />procedure will be followed throughout the operation. As part of the reclamation process, the pit <br />floor will be plated with 4"- 6" of reject gravel material from the mining and processing <br />operations. <br />(b) Earthmoving: <br />Earthmoving will be done with appropriate types and sizes of equipment, i.e. dozers, front-end <br />loaders, scrapers, excavators, etc. Trucks designed (dump trucks, rock haul tricks) to move <br />materials on site will transport material around the mine site and processing area. <br />• Slurry Wall Construction: Slurry or cut-off walls are anon-structural <br />constructed underground barrier to the movement of ground water from one area <br />to another area. Slurry walls aze typically constructed through the excavation of a <br />trench of approximately one yard wide or wider. Bentonite slurry is used to <br />stabilize the trench during construction. Along-reach or rotary excavator is <br />J <br />
