Element 7: Protect Drain Inlets (2.1.7) <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. <br /> However, the first priority is to keep all access roads clean of sediment and keep street wash <br /> water separate from entering storm drains until treatment can be provided. Inlet protection <br /> will be implemented for all drainage inlets and culverts that could potentially be impacted by <br /> sediment-laden runoff on and near the project site. The following inlet protection measures <br /> will be applied on this project: <br /> • Storm Drain Inlet Protection (BMP C220) <br /> Drain inlet protection shall be implemented in the initial stages of construction before the <br /> construction entrance is installed. Inlet protection devices shall be cleaned, removed, or <br /> replaced when sediment has filled the device by one third or as specified by the manufacturer. <br /> Inlets shall be inspected weekly at a minimum and daily during storm events. Sediments that <br /> enter the stormwater conveyance system shall be removed or filtered out by the temporary <br /> sediment pond. If the BMP options listed above are deemed ineffective or inappropriate during <br /> construction to satisfy the requirements set forth in the General NPDES Permit (Appendix D), or <br /> if no BMPs are listed above but deemed necessary during construction, the Certified Erosion <br /> and Sediment Control Lead shall implement one or more of the alternative BMP inlet protection <br /> options listed in Appendix B. <br /> 13 <br />
