1 2.1.8 Element 8: Stabilize Channels and Outlets Where site runoff is to be conveyed in channels, or discharged to a stream or some other natural drainage point, efforts will be taken to prevent downstream erosion. The specific BMPs for channel and outlet stabilization that shall be used on this project include: • Check Dams (BMP C207) • Outlet Protection (BMP C209) Alternate channel and outlet stabilization BMPs are included in Appendix B as a quick reference tool for the onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate during construction to satisfy the requirements set forth in the CSGP (Appendix E). To avoid potential corrosion and sediment control issues that may cause a violation(s) of the CSGP (as provided in Appendix E), the CESL will promptly initiate the implementation of one or more of the alternative BMPs listed in Appendix B after the first sign that existing BMPs are ineffective orfailing. 2.1.9 Element 9: Control Pollutants The following pollutants are anticipated to be present on -site: Table 2 — Pollutants Pollutant (List pollutants and source, if applicable) Landfill materials — buried onsite between 6-15 feet below grade. See Tables 3-1, 3-2, 3-3 in Consent Decree Exhibit C for landfill gas and leachate levels in previous investigations and samplings All pollutants, including waste materials and demolition debris, that occur onsite shall be handled and disposed of in a manner that does not cause contamination of stormwater. Good housekeeping and preventative measures will be taken to ensure that the site will be kept clean, well -organized, and free of debris. The following BMPs will be implemented during construction to control pollutants. • Materials On Hand (BMP C150) • Concrete Handling (BMP C151) • Sawcutting and Surfacing Pollution Prevention (BMP C152) • Material Delivery, Storage and Containment (BMP C153) Per the Federal regulations of the Clean Water Act (CWA) and according to Final Rule 40 CFR Part 112, as stated in the National Register, an SPCC Plan is required for construction activities at the Site. An SPCC Plan will be prepared by the contractor to outline measures to prevent, respond to, and report spills or releases to the environment that could result from construction activities. This Plan is required to: • Be well thought out in accordance with good engineering 1 1 1 1 1 1 1 1 1 n 1 1 1 1 1 1 1 �12 1
