Some TESC Plan required elements typically required by NPDES <br />permits: <br />a. Narrative Site Description: <br />1) Nature of construction activity planned for the Site. <br />2) Estimates of total site area and the areas of the Site expected <br />to be disturbed. <br />3) Soil types found onsite and their erosion potential. <br />4) The types of fill materials to be used. <br />5) Timetable for sequence of major construction events. <br />b. Site Map: <br />1) All areas of development. <br />2) Drainage patterns. <br />3) Areas of soil disturbance, including pre-development and <br />post-development elevation contours. <br />4) Areas used for storage of soils or wastes. <br />5) Areas where vegetative practices are to be implemented. <br />6) Location of all erosion and sediment control BMP or <br />structures. <br />7) Location of all impervious structures and surfaces after <br />project is completed. <br />8) Springs, wetlands, and other surface waters located onsite. <br />9) Boundaries of the 100-year floodplain, if determined. <br />10) Ordinary High Water line, if determined. <br />11) Location of storm drainage outfalls to receiving waters, if <br />applicable. <br />12) Details of sediment and erosion controls. <br />13) Details of detention ponds, storm drain piping, inflow and <br />outflow details. <br />c. Required BMPs and Procedures for Erosion Prevention, Runoff <br />Control, and Sediment Control: <br />1) Construction entrances and parking areas. <br />2) Unpaved site roads such as haul roads. <br />3) Hauling saturated soils from the Site. <br />4) Water washed from concrete trucks. <br />5) Correct installation of erosion and sediment control BMPs. <br />6) Prompt maintenance and repair of BMPs. <br />7) Clearing and grading practices to minimize area of exposed <br />soil throughout life of the Project.
