<br />1.0 EXECUTIVE SUMMARY <br />This Soil Conservation. Erosion and Sediment Control. Reclamation, and Revegetation Plan <br />('The Plan") describes measures to be taken by American Soda, L.L.P. ("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 limiting 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 Design - 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 />Field activities will be carefully planned and organized to ensure that this is accomplished. <br />Field quality assurance and quality control monitoring will be implemented to ensure <br />planning and organizing goals are met. To this end, drill pads will be carefully designed <br />and la;d out to accommodate operations while limiting pad dimensions. Roads used to <br />develop we:: pads and collection gallery pipelines will be carefully arranged to facilitate <br />their development while limiting the linear feet of road required. The size and arangement <br />of processing facilities and supporting utilities will be carefully planned and organized. <br />Environmental veatment and control structures will be incorporated into project design and <br />development to ensure that adequate, realistic environmental protection, mitigation and <br />restoration are achieved in a timely fashion during project development, operation and <br />component closure. Field quality assurance and quality control monitoring will be <br />implemented to ensure that planning and organizational goals are met. <br />Hvdrologic Protection -Paramount to minimizing off-site impacts will be the handling, <br />convol and veatment of surface water run-on and runoff. The placement of water convol <br />and veatment structures will be the first activity undertaken at the commencement of <br />planned disturbance. Water control and veatment 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 veatment structures a high priority during site <br />development. Hydrologic planning will include the diversion of concenvated run-on flows <br />around or safely through disturbed areas. Reconstructed channels or diversions will route <br />concenvated 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 :tnd 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 permanent revegetation operations or stockpiled for future use. In determining which <br />materials constitute the best soil growth mediums, the quality and quantity of topsoil and <br />subsoil, the requirements of the postmining vegetation community for the growth medium, <br />Arrrencan Sala.
