Banks and Gesso, LLC EXHIBIT D -MINING PLAN Overview The Applicant proposes to excavate a total of approximately 2.3 million cubic yards (3.7 million tons) of sand and gravel from the Heit property. The excavation operation will start in 2003 and will last for approximately 7 years. Approximately 500,000 tons of sand and gravel will be mined each year. The actual length of the operation is highly dependant on market conditions. The Applicant proposes to develop the site as a sand and gravel mining and processing operation. Approximately 68 acres of the total permit area of approximately 102 acres is proposed for excavation (see Exhibit C-3: Mining Plan Map). The property will be mined in two phases. Phase1 includes Mine Area 1 and Phase 2 includes Mine Area 2. Mine Area 1 (approximately 61 acres) will be dry mined and Mine Area 2 (approximately 7 acres) will be wet mined. The processing plants will be located in the center of Mine Area 1. The post-mining land use of Mine Area 1 will be a lined water storage reservoir facility, while Mine Area 2 will be reclaimed to enhance wildlife habitat opportunities in the area. Phase 1 Mining Methods The Applicant proposes to dry mine Phase 1. A slurry wall will be installed around the perimeter of the mine area, within the offset along the mining boundary. Dewatering will occur prior to mining. Backfill operations will be concurrent with mining operations. Initial mining operations during Phase 1 will include topsoil and overburden stripping and excavation of dewatering trenches, sedimentation ponds and sump areas. Following topsoil and overburden stripping, raw materials will be excavated with trackhoes and front-end loaders. Excavated materials may be loaded on a field conveyor and transported to the processing plant. Most excavated materials will be removed with scrapers or loaded into off-road haul trucks for transport to the plant site. Excavated materials may also be pushed up with a bulldozer for subsequent handling by front-end loaders. Heit Sand and Gravel Mine 02044 SW Meadow, LLC February 2003 5
