EROSION AND SEDIMENTATION CONTROLS. a. Each SWPPP shall include a written description of appropriate control measures (i.e. Best Management Practices - BMPs) that will be implemented as part of the construction activity to control pollutants in storm water discharges. The written description must clearly describe for each major activity, appropriate control measures and the general timing (or sequence) during the construction process that the measures will be implemented. b. Include an Erosion and Sediment Control Drawing and any control detail drawings illustrating the BMPs as exhibits in Section 10. Ensure the proposed locations of stabilized construction entrances and exits are shown on the Erosion and Sediment Control Drawing (see Section 10 of the A/E Guideline for additional contents of the drawing). c. Include a statement identifying which permittee is responsible for implementation. d. Include statements for Erosion and Sediment Controls - Short and Long Term Goals and Criteria that include the following: (1) The construction-phase erosion and sediment controls should be designed to retain sediment on site to the extent practicable. (2) All control measures must be properly selected, installed and maintained in accordance with the manufacturer's specifications and good engineering practices. If periodic inspections or other information indicates a control has been used inappropriately, or incorrectly, the permittee must replace or modify the control for site situations. (3) If sediment escapes the construction site, off-site accumulations of sediment must be removed at a frequency sufficient to minimize offsite impacts. (i.e. sediment accumulation in streets and curbs) (4) Sediment must be removed from sediment traps or sedimentation ponds when the design capacity has been reduced by 50%. (5) Litter, construction debris, and construction chemicals exposed to storm water shall be prevented from becoming a pollutant source for storm water discharges (i.e. screening outfalls, picked up daily)

e. Stabilization Practices – include a description of interim and permanent stabilization practices for the project site, including a schedule of when the practices will be implemented. Site plans should ensure that existing vegetation is preserved where attainable and that disturbed portions of the site are stabilized. Use of impervious surfaces for stabilization should be avoided. Stabilization practices may include, but are not limited to:
(1) Establishment of temporary vegetation
(2) Establishment of permanent vegetation (3) Mulching (4) Geotextiles
