11 Non-Stormwater Discharge and/or Source Applicable CASQA BMP Fact Sheet Potable/Irrigation water NS-7 Vehicle and equipment cleaning NS-8 Vehicle and equipment fueling NS-9 Vehicle and equipment maintenance NS-10 Pile driving operations NS-11 Concrete curing and finishing NS-12, NS-13 Concrete waste WM-8 Material handling, storage, and/or spills WM-1, WM-2, WM-4 Stockpiles WM-3 Santiary/Septic waste (from temporary sanitary facilities) WM-9 The associated BMPs for minimizing or eliminating non-stormwater discharges are described in Section 3.3. The applicable CASQA BMP fact sheets are included in Appendix G. SECTION 3 - BEST MANAGEMENT PRACTICES SECTION 3.1 - SCHEDULE FOR BMP IMPLEMENTATION The contractor shall include specific BMP implementation within the project schedule. Generally, BMPs in areas to remain undisturbed throughout construction (such as sediment filters and burlap bags at existing inlets and perimeter erosion control) should be implemented prior to mass grading. BMPs for new storm drain should be implemented shortly after installation. Any mass graded areas to remain exposed for significant lengths of time during construction should be stabilized using hydroseed and/or covered. The BMP implementation schedule shall be posted in the job trailer with the overall project schedule and included in this SWPPP in Appendix F for reference. See CASQA Fact Sheet EC-1 located in Appendix G for more information. SECTION 3.2 - EROSION AND SEDIMENT CONTROL Erosion control is any source control practice that protects the soil surface and prevents oil particles from being detached by rainfall, flowing water, or wind. Erosion control measures are retroactive BMPs designed to stabilize the soil. They are implemented immediately following a construction operation(s) that exposes soil or decrease the stability of the soil. Sediment control is any practice that traps soil particles after they have been detached and moved by rain, flowing water, or wind. Sediment control measures are preventive BMPs designed to retain soil or sediment from leaving the site and/or entering the storm drain. They are usually implemented prior to construction operations that disturb the soil. The following are primary erosion control measures that may apply to this project and are to be implemented if needed as determined by the Erosion Control Plan, QSD, QSP or contractor. If
