Stormwater Pollution Prevention Plan <br /> In general, cut and fill slopes will be stabilized as soon as possible and soil stockpiles will be <br /> ' temporarily covered with plastic sheeting. All stockpiled soils shall be stabilized from erosion, <br /> protected with sediment trapping measures, and where possible, be located away from storm <br /> drain inlets, waterways, and drainage channels. <br /> ' 3.1.6 Element #6 — Protect Slopes <br /> ' All cut and fill slopes will be designed, constructed, and protected in a manner that minimizes <br /> erosion. The following specific BMPs will be used to protect slopes for this project: <br /> ' ■ Temporary and Permanent Seeding (BMP C 120) <br /> Temporary and permanent seeding shall be used at all exposed areas pursuant to the prior <br /> ' mentioned schedule (seasonal restrictions). <br /> Alternate slope protection BMPs are included in Appendix C as a quick reference tool for the <br /> onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate <br /> during construction to satisfy the requirements set forth in the General NPDES Permit <br /> (Appendix D). To avoid potential erosion and sediment control issues that may cause a <br /> I <br /> violation(s) of the NPDES Construction Stormwater permit (as provided in Appendix D), the <br /> Certified Erosion and Sediment Control Lead will promptly initiate the implementation of one or <br /> more of the alternative BMPs listed in Appendix C after the first sign that existing BMPs are <br /> ineffective or failing. <br /> 3.1.7 Element #7 — Protect Drain Inlets <br /> All storm drain inlets and culverts made operable during construction shall be protected to <br /> prevent unfiltered or untreated water from entering the drainage conveyance system. However, <br /> ' the first priority is to keep all access roads clean of sediment and keep street wash water <br /> separate from entering storm drains until treatment can be provided. Storm Drain Inlet <br /> Protection (BMP C220)will be implemented for all drainage inlets and culverts that could <br /> potentially be impacted by sediment-laden runoff on and near the project site. The following <br /> inlet protection measures will be applied on this project: <br /> ' • Excavated Drop Inlet Protection <br /> • Block and Gravel Drop Inlet Protection <br /> ' • Gravel and Wire Drop Inlet Protection <br /> • Catch Basin Filters <br /> ' • Culvert Inlet Sediment Trap <br /> If the BMP options listed above are deemed ineffective or inappropriate during construction to <br /> satisfy the requirements set forth in the General NPDES Permit(Appendix D), or if no BMPs are <br /> listed above but deemed necessary during construction, the Certified Erosion and Sediment <br /> ' Control Lead shall implement one or more of the alternative BMP inlet protection options listed <br /> in Appendix C. <br /> ' 7 16580.006.doc <br />
