Banks and Gesso, LLC <br />MINING PLAN (as submitted to the DMG under their Exhibit D) <br />Overview <br />T h e applicant proposes to expand the existing sand and gravel mining site. <br />Sand and gravel from the expansion areas will be processed at the existing <br />processing plant. Approximately 140 acres of the total permit area acreage of <br />approximately 287 acres is proposed for new mining (see Exhibit C-3, Mining <br />Plan Map). The mining area will be contiguous to the currently permitted <br />operation, and will be dry-mined. The proposed excavation areas will be <br />reclaimed as water-storage reservoirs surrounded by a combination compacted <br />clay liner and impermeable slurry wall that will be constructed in phases, during <br />the mining operations. The previously mined northern area will be reclaimed as <br />an un-lined wildlife pond. The edges of the reservoirs will 6e reclaimed to an <br />irregular shoreline. The post-mining land use of the property is for water storage <br />and surrounding wildlife habitat. The existing access from Riverdale Road will be <br />maintained for the future owner of the water storage reservoir. Since some of the <br />materials are only suitable as structural fill, the final total area mined depends on <br />the sale of these fill materials, and the final area mined may be smaller than <br />permitted. The Reclamation Plan assumes the cost for restoration of the <br />maximum mining area as water storage reservoirs and wildlife habitat. <br />fa) Mining Methods <br />The Applicant proposes to dry-mine the properly. The initial mining will occur <br />near the northern end of the South Reservoir, expanding the existing mine area, <br />and progressing southward.
