1.0 EXECUTIVE SUMMARY This Soil Conservation, Erosion and Sediment Control, Reclamation, and Revegetation Plan (`The Plan") describes measures to be taken by American Soda, L.L.P. ("American Soda") and its contractors to protect and restore azeas of disturbance associated with mine development, operation and retirement. The Plan ensures that 1) surface disturbance will be minimized, 2) erosion and sedimentation will be controlled, 3) topsoil will be salvaged and stockpiled, 4) disturbed areas will be recontoured to approximate original topography, and 5) disturbed areas will be revege[ated and monitored to ensure adequate species and habit diversity. The prescribed resource protection procedures and practices focus on avoiding disturbance whenever possible and limiting disturbance to the extent practicable. These procedures and practices are included in planning and design, hydrologic protection, soil resource salvage and reconswction, and contemporaneous revegetation. • Planning and Design - American Soda will manage mining operations to limit environmental impacts resulting from its activities. This will primarily be accomplished by m;n;miring disturbance associated with development to the max;mum extent practicable. Field activities will be carefully planned and organized to ensure that this is accomplished. Field quality assurance and quality control monitoring will be implemented to ensure planning and organizing goals are met. To this end, drill pads will be cazefully designed and laid out to accommodate operations while limiting pad dimensions. Roads used to develop well pads and collection gallery pipelines will be carefully arranged to facilitate their development while limiting the lineaz feet of road required. The size and arrangement of processing facilities and supporting utilities will be carefully planned and organized. Environmental treatment and control swctures will be incorporated into project design and development to ensure thaz adequate, realistic environmental protection, mitigation and restoration are achieved in a timely fashion during project development, operation and component closure. Field quality assurance and quality control monitoring will be implemented to ensure that planning and organizational goals are met. Hydrologic Protection -Paramount to m;n;mi~ing off-site impacts will be the handling, control and treatment of surface water run-on and runoff. The placement of water control and treatment swctures will be the first activity undertaken az the commencement of planned disturbance. Water control and treatment swctures will generally be the last swctures to be removed following successful establishment of permanent vegetation on disturbed areas. American Soda will protect surface water quality by making the installation of hydrologic control and treatment swctures a high priority during site development. Hydrologic planning will include the diversion of concentrated run-on flows azound or safely through disturbed areas. Reconswcted channels or diversions will route concentrated surface flows from disturbed areas through appropriate erosion and sediment control swctures and facilities. Such channels and diversions will be adequately designed and stabilized to carry the flow volumes for which they are intended. • Soil Resource Salvage and Reconswction -Topsoil and soil resource surveys are available for the areas to be disturbed. The best available soil reconswction mazerials will be salvaged during initial disturbance and either immediately replaced on lands that are ready for permanent revegetation operations or stockpiled for future use. In deter*n;n;ng which materials constitute the best soil growth mediums, the quality and quantity of topsoil and subsoil, the requirements of the postmining vegetation community for the growth medium, Americm Soda.
