3.1.6 Element#6—Protect Slopes <br /> All cut and fill slopes shall be designed, constructed, and protected in a manner that minimizes <br /> erosion. <br /> Interceptor dikes and swales are to be installed as necessary to collect any potential off-site <br /> stormwater run-on as well as collect and direct on-site stormwater to a temporary sediment pond. <br /> Check dams will be installed at regular intervals along the interceptor dike and swale to help <br /> reduce potential erosion cause by high runoff velocities from onsite slopes. <br /> 3.1.7 Element#7—Protect Drain Inlets <br /> All storm drain inlets and culverts existing or made operable during construction shall be <br /> protected to prevent unfiltered or untreated water from entering the drainage conveyance system. <br /> However, the first priority is to keep all access roads clean of sediment and keep street wash <br /> water separate from entering storm drains until treatment can be provided. Storm Drain Inlet <br /> Protection (BMP C220) will be implemented for all drainage inlets and culverts that could <br /> potentially be impacted by sediment-laden runoff on and near the project site. The following <br /> inlet protection measures will be applied on this project: <br /> BMP C220: Storm Drain Inlet Protection <br /> Catch basin filters are to be installed on all catchbasins within 300 feet of the active work area to <br /> protect the downstream waters and reduce the potential for material to enter the storm system. <br /> 3.1.8 Element#8—Stabilize Channels and Outlets <br /> BMP C207: Check Dams <br /> BMP C209: Outlet Protection <br /> 3.1.9 Element#9—Control Pollutants <br /> All pollutants, including waste materials and demolition debris, that occur onsite shall be <br /> handled and disposed of in a manner that does not cause contamination of stormwater. Good <br /> housekeeping and preventative measures will be taken to ensure that the site will be kept clean, <br /> well-organized, and free of debris. If required, BMPs to be implemented to control specific <br /> sources of pollutants are discussed below. <br /> Vehicles, construction equipment, and/or petroleum product storage/dispensing: <br /> • All vehicles, equipment, and petroleum product storage/dispensing areas will <br /> be inspected regularly to detect any leaks or spills, and to identify <br /> maintenance needs to prevent leaks or spills. <br /> • On-site fueling tanks and petroleum product storage containers shall include <br /> secondary containment. <br /> UNDERWOOD GARTLAND JOHNSON 63,LLC April 2017 <br /> Stormwater Pollution Prevention Plan Page 6 <br />
