Section 3 Best Management PracticesBest Management Practices (BMPs) were chosen for this project to reduce or eliminate pollutants in stormwater discharge, and to comply with the Provisions of Attachment D of the General Order (Risk Level 2Requirements) as well as those in the General Permit Order. BMPs are shown in the erosion and sedimentcontrol plan provided in Appendix C.The General Permit Order requires:Dischargers shall minimize or prevent pollutants in storm water discharges and authorized non-storm waterdischarges through the use of controls, structures, and management practices that achieve Best AvailableTechnology Economically Achievable (BAT) for toxic and non-conventional pollutants and Best ConventionalPollutant Control Technology (BCT) for conventional pollutants.Storm water discharges and authorized non-storm water discharges regulated by this General Permit shall notcontain a hazardous substance equal to or in excess of reportable quantities established in 40 C.F.R. §§ 117.3and 302.4, unless a separate NPDES Permit has been issued to regulate those discharges.As a Risk level 2 discharger this project is subject to Numeric Action Levels (NALs) for pH and turbidity asdescribed in Section 3.4.3.1 BMP Installation ScheduleThe Contractor is responsible for ensuring that appropriate BMPs are in place during the operations requiringthe BMPs. Below is a schedule intended to provide the minimum BMPs necessary during each phase of thecontractor’s operation. Additional BMPs may be necessary. Some BMPs installed early in the project shallremain in place upon completion of the project, while others must be removed prior to the completion of theproject. Appendix E provides BMP Fact Sheets on design and implementation guidelines for each BMP.The following BMPs shall be installed / utilized prior to clearing and grubbing operations:EC-1 SchedulingEC-2 Preservation of Existing VegetationSE-7 Street Sweeping and VacuumingNS-6 Illicit Connection/DischargeNS-9 Vehicle and Equipment FuelingNS-10 Vehicle & Equipment MaintenanceWM-1 Material Delivery and StorageWM-2 Material UseWM-3 Stockpile ManagementWM-4 Spill Prevention and ControlWM-5 Solid Waste ManagementWM-6 Hazardous Waste ManagementWM-9 Sanitary/Septic Waste ManagementIf materials are stockpiled on-site and the stockpiles are inactive (not scheduled to be re-disturbed for at least14 days), then the stockpiled areas shall be covered and a berm placed around the materials in accordancewith WM-3 “Stockpile Management.”The following BMPs shall be installed / utilized during grading/mobilization operations:WE-1 Wind Erosion ControlTC-1 Stabilized Construction Entrance/ExitNS-1 Water Conservation PracticesSE-1 Silt FenceSE-5 Fiber RollsThe following BMPs shall be installed / utilized upon completion of drainage work:EC-10 Velocity Dissipation DevicesMunicipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 10
SE-10 Storm Drain Inlet ProtectionThe following BMPs shall be installed / utilized during paving operations:NS-3 Paving and Grinding OperationsThe following BMPs shall be installed / utilized during concrete operations:NS-12 Concrete CuringNS-13 Concrete FinishingWM-8 Concrete Waste ManagementThe following BMPs shall be installed / utilized during slope stabilization operations:EC-6 Straw Mulch/Hydroseed/Tackifier/Soil AmendmentEC-7 Geotextiles & Mats (biodegradable option)All BMPs, except those designated as post-construction BMPs in Section 3.4, are to be removed prior tocontract acceptance.3.2 Erosion & Sediment Control Best Management PracticesAppendix E provides BMP Fact Sheets on design and implementation guidelines for each BMP to reduce oreliminate pollutants in stormwater discharges. All BMPs are required to be implemented.The following BMPs are to be incorporated into this SWPPP:EC-1 SchedulingEC-2 Preservation of Existing VegetationEC-6 Straw Mulch/Hydroseed/Tackifier/Soil AmendmentEC-7 Geotextiles & Mats (biodegradable option)EC-10 Velocity Dissipation DevicesSE-1 Silt FenceSE-5 Fiber RollsSE-7 Street Sweeping and VacuumingSE-10 Storm Drain Inlet ProtectionWM-3 Stockpile Management3.3 Non-Stormwater and Material Management Best Management PracticesNon-storm water discharges may contribute significant pollutant loads to receiving waters. Measures to controlspills, leakage, and dumping, and to prevent illicit connections during construction must be addressed throughstructural as well as non-structural Best Management Practices (BMPs).BMPs are designated in this SWPPP to prevent non-stormwater discharges.
