of protection measures. American Soda recognizes that the design and implementation of erosron and sediment control measures is a dynamic process and that annual review and consultation with agencies must be incorporated into project planning to ensure that prescribed measures adequately meet The Plan objectives and goals. Examples of physical BMPs include constructing water bars across roads, placing geotextile fabrics or other types of temporary cover on cut or fill slopes, and installing silt fences and straw bale fillets down-gradient from disturbed areas. Effective usage of BMPs must be based on the consideration of existing site-specific conditions and must be cost effective. Factors that need to be considered in establishing BMPs include the occurrence and movement of surface and ground water, geology, soil physical chazacteristics, climate, topography, vegetation and habitaz. Scheduling and timing are important, as are adequate site-specific design and application. Typical BMP construction schematics referenced in subsequent sections are contained in Appendices A through E of The Plan. There aze a number of general planning and operating considerations that are applicable to both soil conservation and erosion and sediment control structures, practices and planning. General considerations described herein will be implemented to minimize environmental impacts during construction and operation of the project, and during project component closure and restoration. Planning and operating considerations include, but are not limited to, the following: • Equipment, supplies and personnel will stay within the disturbance area boundary at all times to prevent disturbance to non-operational areas; • Temporary erosion and sediment controls will be installed prior to disturbance or as soon as practicable thereafter, • Temporary erosion and sediment controls will be timely maintained until replaced by permanent controls or practices; • Periodic inspections will be performed to ensure that controls aze adequate and are functioning correctly; • Construction disturbance will be limited in areal extent to that which is operationally necessary; • Operations and activities will be m;n;m;~rlt during periods when inclement weather or adverse ground conditions exist thaz could adversely affect natural resources or the ability to use them; • Good housekeeping practices will be followed, including performance of routine job clean up and contemporaneous reclamation; • Adequate materials and supplies will be kept available on site for construction and maintenance activities; • Facility and transportation structures will be planned and located to m;nim;~r surface • disturbance; American Soda, L1.P. 3-3 Soil Conutvauon, Erosion and Sediment Control.
