1.0 Introduction In 1972, Congress passed the Federal Water Pollution Control Act(FWPCA), also known as the Clean Water Act(CWA), to restore and maintain the quality of the nation's waterways. The ultimate goal was to make sure that rivers and streams were fishable, swimmable, and drinkable. In 1987, the Water Quality Act(WQA)added provisions to the CWA that allowed the Environmental Protection Agency to govern stormwater discharges from construction sites. The National Pollutant Discharge Elimination System (NPDES)General Permit includes provisions for development of a Stormwater Pollution Prevention Plan (SWPPP)to maximize the potential benefits of pollution prevention and sediment and erosion control measures at construction sites. IDevelopment, implementation, and maintenance of the Construction SWPPP (CSWPPP)will provide the selected General Contractor with the framework for reducing soil erosion and minimizing pollutants in stormwater during construction of the proposed improvements. This CSWPPP will: • Define the characteristics of the site and the type of construction that will occur. • Describe the existing site conditions, including existing land use, soil types at the site, and the location of surface waters that are located on or next to the site. • Identify the body or bodies of water that will receive runoff from the construction site, including the ultimate body of water that receives the stormwater. • Identify the drainage areas and potential stormwater contaminants. • Describe the stormwater management controls and various Best Management Practices (BMPs)necessary to reduce erosion, sediment, and pollutants in stormwater discharge. I . Create an implementation schedule to ensure that the practices described in this CSWPPP are in fact implemented, and to evaluate the plan's effectiveness in reducing erosion, sediment, and pollutant levels in stormwater discharged from the site. • Identify the CSWPPP Coordinator with a description of this person's duties. • Identify the Stormwater Pollution Prevention Team (SWPP Team)that will assist in implementation of the CSWPPP during construction. • Describe the facility monitoring plan and how controls will be coordinated with construction activities. • Describe the implementation schedule and provisions for amendment of the plan. ' • Describe the final stabilization/termination design to minimize erosion and prevent stormwater impacts after construction is complete. 1 I Construction Stormwater Pollution Prevention Plan The Bethany at Silver Lake 1 2180406.10
