Stormwater Pollution Prevention Plan <br /> 3.0 Construction Stormwater BMPs <br /> 3.1 The 12 BMP Elements <br /> 3.1.1 Element#1 —Mark Clearing Limits <br /> To protect adjacent properties and to reduce the area of soil exposed to construction, the limits of <br /> construction will be clearly marked before land-disturbing activities begin. Trees that are to be <br /> preserved, as well as all sensitive areas and their buffers, shall be clearly delineated, both in the <br /> field and on the plans. In general, natural vegetation and native topsoil shall be retained in an <br /> undisturbed state to the maximum extent possible. The BMPs relevant to marking the clearing <br /> limits that will be applied for this project include: <br /> • High Visibility Plastic or Metal Fence(BMP C103) <br /> Alternate BMPs for marking clearing limits are included in Appendix C as a quick reference tool <br /> for the onsite inspector in the event the BMP(s) listed above are deemed ineffective or <br /> inappropriate during construction to satisfy the requirements set forth in the General NPDES <br /> Permit (Appendix D). To avoid potential erosion and sediment control issues that may cause a <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 /> 3.1.2 Element#2—Establish Construction Access <br /> Construction access or activities occurring on unpaved areas shall be minimized, yet where <br /> necessary, access points shall be stabilized to minimize the tracking of sediment onto public <br /> roads, and wheel washing, street sweeping, and street cleaning shall be employed to prevent <br /> sediment from entering state waters. All wash wastewater shall be controlled on site. The <br /> specific BMPs related to establishing construction access that will be used on this project <br /> include: <br /> • Stabilized Construction Entrance (BMP C105) <br /> Alternate construction access 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 (Appendix <br /> D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the <br /> NPDES Construction Stormwater permit (as provided in Appendix D),the Certified Erosion and <br /> Sediment Control Lead will promptly initiate the implementation of one or more of the <br /> alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or <br /> failing. <br /> 5 <br />
