C. STORMWATER MANAGEMENT PLAN (SWMP)— CONTENTS (cont.) 3. Stormwater Management Controls. PART I Permit - Page 8 Permit No COR- 030000 The SWMP must include a description of all stormwater management controls that will be implemented as part of the construction activity to control pollutants in stormwater discharges. The appropriateness and priorities of stormwater management controls in the SWMP shall reflect the potential pollutant sources identified at the facility. The description of stormwater management controls shall address the following components, at a minimum: a) SWMP Administrator - The SWMP shall identify a specific individual(s), position or title who is responsible for developing. implementing. maintaining, and revising the SWMP. The activities and responsibilities of the administrator shall address all aspects of the facility's SWMP. b) Identification of Potential Pollutant Sources - All potential pollutant sources. including materials and actin ities. at a site must be evaluated for the potential to contribute pollutants to stormwater discharges fhe SWMP shall identify and describe those sources determined to have the potential to contribute pollutants to stormwater discharges. and the sources must he controlled through BMP selection and implementation. as required in paragraph (c). below. At a minimum. each of the following sources and activities shall be evaluated for the potential to contribute pollutants to stormwater discharges, and identified in the SWMP if found to have such potential: 1) all disturbed and stored soils; 2) vehicle tracking of sediments; 3) management of contaminated soils; 4) loading and unloading operations; 5) outdoor storage actin ities (building materials, fertilizers. chemicals. etc.): \ chicle and equipment maintenance and fueling: 7) signilicant dust or particulate generating processes: 8) routine maintenance actin ities involving fertilizers. pesticides. detergents. fuels, solvents. oils. etc.: 9) on -site waste management practices (waste piles. liquid wastes. dumpsters, etc.): 10) concrete truck/equipment washing. including the concrete truck chute and associated fixtures and equipment: 1 I) dedicated asphalt and concrete batch plants; 12) non - industrial waste sources such as worker trash and portable toilets; and 13) other areas or procedures where potential spills can occur. c) Best Management Practices (BMPs) for Stormwater Pollution Prevention - The SWMP shall identify and describe appropriate BMPs, including, but not limited to, those required by paragraphs 1 through 8 below, that will be implemented at the facility to reduce the potential of the sources identified in Part I.C.3.b to contribute pollutants to stormwater discharges. The SWMP shall clearly describe the installation and implementation specifications for each 13M1 identified in the SW VIP to ensure proper implementation. operation and maintenance of the [IMP I 1 Structural Practices for Erosion and Sediment Control I he Sbl MP shall eIearl\ describe and locate all structural practices implemented at the site to minimize erosion and sediment transport. Practices ma■ include. but are not limited to• straw hales, wattles /sediment control logs. silt fences. earth dikes. drainage swalcs. sediment traps. subsurface drains. pipe slope drains. inlet protection. outlet protection. gahions. and temporary or permanent sediment basins. 2) Non - Structural Practices for Erosion and Sediment Control. The SWMP shall clearly describe and locate, as applicable. all non - structural practices implemented at the site to minimize erosion and sediment transport. Description must include interim and permanent stabilization practices, and site - specific scheduling for implementation of the practices. The SWMP should include practices to ensure that existing vegetation is presen cd w here possible. Non - structural practices may include. but are not limited to: temporary vegetation. permanent vegetation. mulching, geotextiles, sod stabilization. slope roughening, vegetative butter strips. protection of trees. and prescr\,aton of mature v egetation.
