<br />of protection measures. American Soda recognizes that the design and implementation of <br />erosion and sediment control measures is a dynamic process and that annual review and <br />consultation with agencies must be incorporated into project planning to ensure that prescribed <br />measures adequately meet The Plan objectives and goals. <br />Examples of physical BMPs include constructing water bars across roads, placing geotextile <br />fabrics or other types of temporary cover on cut or fill slopes, and installing silt fences and <br />straw bale filters down-gradient from disturbed areas. Effective usage of BMPs must be based <br />on the consideration of existing site-specific conditions and must be cost effective. Factors that <br />need to be considered in establishing BMPs include the occurrence and movement of surface <br />and ground water, geology, soil physical characteristics, climate, topography, vegetation and <br />habitat. Scheduling and timing are important, as are adequate site-specific design and <br />application. Typical BMP construction schematics referenced in subsequent sections are <br />contained in Appendices A through E of The Plan. <br />There are a number of general planning and operating considerations that are applicable to both <br />soil conservation and erosion and sediment control structures, practices and planning. General <br />considerations described herein will be implemented to minimize environmental impacts during <br />construction and operation of the project, and during project component closure and <br />restoration. Planning and operating considerations include, but are not limited to, the <br />following: <br />• Equipment, supplies and personnel will stay within the disturbance area boundary at all <br />times to prevent disturbance to non-operational areas; <br />• Temporary erosion and sediment controls will be installed prior to disturbance or as soon <br />as practicable thereafter: <br />• Temporary erosion and sediment controls will be timely maintained until replaced by <br />permanent controls or practices: <br />• Periodic inspections will be performed to ensure that controls are adequate and are <br />functioning correctly; <br />• Construction disturbance will be limited in areal extent to that which is operationally <br />necessary; <br />• Operations and activities will be minimized during periods when inclement weather or <br />adverse ground conditions exist that could adversely affect natural resources or the ability <br />to use them; <br />• Good housekeeping practices will be followed, including performance of routine job clean <br />up and contemporaneous reclamation: <br />• Adequate materials and supplies will be kept available on site for construction and <br />maintenance activities; <br />• Facility and transporation structures will be planned and located to minimize surface <br />disturbance; <br />American S«la, L.L.P. 3-3 <br />Soil Conscrvmon.
