("American Soda") and <br />its contractors to protect and restore areas of disturbance associated with mine development, <br />operation and retirement The Plan ensures that 1) surface disturbance will be minimized, 2) <br />erosion and sedimentation will be controlled, 3) topsoil will be salvaged and stockpiled, 4) <br />disturbed areas will be recontoured to approximate original topography, and 5) disturbed areas <br />will be revegetated and monitored to ensure adequate species and habit diversity. <br />The prescribed resource protection procedures and practices focus on avoiding disturbance <br />whenever possible and I'tmiting disturbance to the extent practicable. These procedures and <br />practices are included in planning and design, hydrologic protection, soil resource salvage and <br />reconstruction, and contemporaneous revegetation. <br />Planning and lksign -American Soda will manage mining operations to limit <br />environmental impacts resulting from its activities. This will primarily be accomplished by <br />minimizing disturbance associated with development to the maximum extent practicable. <br />Feld activities will be carefully planned and organized to ensure that this is accomplished. <br />Feld quality assurance and control monitoring will be implemented to ensure planning and <br />organizing goals are met To this end, drIIl pads will be carefully designed and laid out to <br />accommodate operations while limiting pad dimensions. Roads used to develop well pads <br />and collection gallery pipelines will be carefully arranged to facilitate their development <br />while limiting the linear feet of road required. The size and arrangement of processing <br />facilities and supporting utilities will be carefully planned and organized. Environmental <br />treatment and control structures will be incorporated into project design and development to <br />ensure that adequate, realistic environmental protection, mitigation and restoration are <br />achieved in a timely fashion during project development, operation and component closure. <br />Feld quality assurance and quality control monitoring will be implemented to ensure that <br />planning and organizational goals are met <br />Hydrologic Protection -Paramount to minimizing off-site impacts will be the handling, <br />control and treatment of surface water run-on and runoff. The placement of water control <br />and treatment structures will be the fast activity undertaken at the commencement of <br />planned disturbance. Water control and treatment structures will generally be the last <br />structures to be removed following successful establishment of permanent vegetation on <br />disturbed areas. American Soda will protect surface water quality by making the <br />installation of hydrologic control and treatment structures a high priority during site <br />development Hydrologic planning will include the diversion of concentrated run-on flows <br />around or safely through disturbed areas. Reconstructed channels or diversions will route <br />concentrated surface flows from disturbed areas through appropriate erosion and sediment <br />control structures and facilities. Such channels and diversions will be adequately designed <br />and stabilized to carry the flow volumes for which they are intended. <br />• Soil Resource Salvage and Reconstruction -Topsoil and soil resource surveys are available <br />' for the areas to be disturbed. The best available soil reconstruction materials will be <br />salvaged during initial disturbance and either immediately replaced on lands that are ready <br />for pemlanent revegetation operations or stockpiled for future use. In detemrining which <br />' materials constitute the best soil growth mediums, the quality and quantity of topsoil and <br />subsoil, the requirements of the postrnining vegetation community for ilia growth medium, <br />and the topography of the area to be reclaimed will be considered. Soils will be <br />1 Americo Soda, LLP. 1-1 <br />Soil Consmatiaq Fiosi~ gad Sediment <br />' Conwl, RedamaGoa and ReveEetatioo Plm <br />October 28, 1998 <br />
