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. The proposed project will not disturb more than 1 acre of area, and therefore is not required to obtain an NPDES General Permit for Stormwater Associated with Construction Activities. Development, implementation, and maintenance of the Construction SWPPP will provide the selected General Contractor with the framework for reducing soil erosion and minimizing pollutants in stormwater during construction. The Construction SWPPP will: • Define the characteristics of the site and the type of construction that will occur. • Describe the practices that will be implemented to control erosion and the release of pollutants in stormwater. • Create an implementation schedule to ensure that the practices described in this Construction SWPPP are in fact implemented and to evaluate the plan's effectiveness in reducing erosion, sediment, and pollutant levels in stormwater discharged from the site. • Describe the final stabilization/termination design to minimize erosion and prevent stormwater impacts after construction is complete. This Construction SWPPP includes the following: • Identification of the Certified Erosion and Sediment Control Lead (CESCL) with a description of this person's duties. • Identification of the Stormwater Pollution Prevention Team (SWPP Team) that will assist in implementation of the Construction SWPPP during construction. • Description of the existing site conditions, including existing land use for the site, soil types at the site, and the location of surface waters that are located on or next to the site. • Identification of the body or bodies of water that will receive runoff from the construction site, including the ultimate body of water that receives the stormwater. • Identification of drainage areas and potential stormwater contaminants. • Description of stormwater management controls and various Best Management Practices (BMPs) necessary to reduce erosion, sediment, and pollutants in stormwater discharge. • Description of the facility -monitoring plan and how controls will be coordinated with construction activities. • Description of the implementation schedule and provisions for amendment of the plan.
