Ms. Erica Crosby, Division of Minerals and Geology March 23, 2005 Page 13 ~~ baseline conditions prior to mining and to enable groundwater monitoring durin~ hYih~n~E sou ac Es, uc The operator will develop and comply with a stormwater management plan and will use best management practices (BMPs) to ensure groundwater and surface water are protected to the greatest possible extent. BMPs include schedules of activities, prohibitions of practices, maintenance procedures and other management practices to prevent or reduce the pollution in runoff from the site. ^ The Operator will stabilize and protect all surface areas of the affected land, including spoil piles so as to effectively control erosion. This will be done through concurrent reclamation which minimizes the exposed material stockpiled, installation of silt fence as necessary and by establishing vegetation if an area is to remain undisturbed for a significant period of time. ^ The Operator will comply with all standards and conditions applicable to classified and unclassified groundwater. The Operator will protect the existing and "reasonably potential" future uses of groundwater. We are in the process of applying for a well permit and are preparing a Temporary Substitute Water Supply Plan to augment evaporative losses from the ponds. • The mining and reclamation plans have been designed to account for the safety and protection of wildlife on the mine site and at the processing area. Currently, the majority of the property is farmed to the edge and provides minimal wildlife habitaf. The Operator will mine the site in phases and use concurrent reclamation methods to minimize the impact on wildlife. The proposed plantings are designed to provide additional food, cover and nesting areas for wildlife. The Operator will also convey materjals as much as possible to minimize the use of haul trucks on the site. The Operator will comply with the Noise Emissions Analysis recommendations to minimize noise emissions on site. ^ Topsoil shall be removed and segregated from other spoil. Topsoil stockpiles shall be stored in places and configurations to minimize erosion and located in areas where disturbance by ongoing mining operations will be minimized. Once stockpiled, topsoil shall be re-handled as little as possible. The topsoil used for perimeter seeding berms will be seeded to dryland grass (per the Mining Landscape Plan) to control weeds and prevent erosion. • In those areas where revegetation is part of the reclamation plan, land shall be revegetatetl in a manner that establishes a diverse, effective, and long-lasting vegetative cover that is capable of self-regeneration without continued dependence on irrigation or fertilizer and is at least equal in extent of cover to the natural vegetation of the surrounding area. Refer to the Reclamation Plan Map and Landscaping Maps for details. • The Operator will post appropriate signage at the entrance to the mine site and the boundaries of the affected site will be clearly marked. 31. The applicant states that topsoil will be uniformly placed and spread on areas disturbed by the mining, above the anticipated high water line. Please state where the high water line is anticipated, and depict this area on the reclamation plan map. Please refer to the Reclamation Plan Map for the final slopes and the open lake reclamation detail that illustrates the compacted clay liner in relation to the high water line (maximum water surface).
