Technical Information Report July 2015 <br /> Everett Self-Storage <br /> 5.1.6 Element#6— Protect Slopes <br /> All cut and fill slopes are required to be designed, constructed, and protected in a manner that <br /> minimizes erosion. The project site has no sloped areas, therefore no BMPs are necessary for this <br /> element. <br /> • Plastic Covering (BMP C123) <br /> 5.1.7 Element #7— Protect Drain Inlets <br /> All storm drain inlets and culverts made operable during construction shall be protected to prevent <br /> unfiltered or untreated water from entering the drainage conveyance system. However, the first <br /> priority is to keep all access roads clean of sediment and keep street wash water separate from <br /> entering storm drains until treatment can be provided. Storm Drain Inlet Protection (BMP C220) will <br /> be implemented for all drainage inlets and culverts that could potentially be impacted by sediment- <br /> laden runoff on and near the project site. The following inlet protection measures will be applied on <br /> this project: <br /> • Storm Drain Inlet Protection (BMP C220) (off-site area if needed and on-site after <br /> construction of storm system) <br /> 5.1.8 Element #8—Stabilize Channels and Outlets <br /> Where site runoff is to be conveyed in channels, or discharged to a stream or some other natural <br /> drainage point, efforts will be taken to prevent downstream erosion. Since no site run off will be <br /> discharging to a channel or any natural drainage point, no specific BMPs are required to meet this <br /> element. <br /> • Construction monitoring if required by the City <br /> • Materials on Hand (BMP C150) <br /> 5.1.9 Element #9—Control Pollutants <br /> All pollutants, including waste materials and demolition debris, that occur on-site shall be handled <br /> and disposed of in a manner that does not cause contamination of stormwater. Good housekeeping <br /> and preventative measures will be taken to ensure that the site will be kept clean, well organized, <br /> and free of debris. If required, BMPs to be implemented to control specific sources of pollutants are <br /> discussed below. <br /> Vehicles, construction equipment, and/or petroleum product storage/dispensing: <br /> • All vehicles, equipment, and petroleum product storage/dispensing areas will be inspected <br /> regularly to detect any leaks or spills, and to identify maintenance needs to prevent leaks or <br /> spills. <br /> • On-site fueling tanks and petroleum product storage containers shall include secondary <br /> containment. <br /> • Spill prevention measures, such as drip pans, will be used when conducting maintenance <br /> and repair of vehicles or equipment. <br /> 14114 Everett Storage TfR Revised 0715.doc 35 <br /> 49 <br />
