Stormwater Pollution Prevention Plan <br /> 3.1.4 Element#4—Install Sediment Controls <br /> All stormwater runoff from disturbed areas shall pass through an appropriate sediment removal <br /> BMP before entering a receiving water body. The following relevant BMPs for this project <br /> include: <br /> BMP C220: Storm Drain Inlet Protection <br /> BMP C233: Silt Fence <br /> BMP C240: Sediment Trap <br /> At the end of construction the city shall inspect the underground detention vault to ensure it is <br /> cleaned of any sediment and ready for use as strictly a flow control facility. <br /> 3.1.5 Element#5—Stabilize Soils <br /> Exposed and unworked soils shall be stabilized with the application of effective BMPs to prevent <br /> erosion throughout the life of the project. The following relevant BMPs for this project include: <br /> BMP C 123: Plastic Covering <br /> BMP C 140: Dust Control <br /> In general, cut and fill slopes shall be stabilized if they are to remain unworked for a certain <br /> period of time depending on the season. If a soil stockpile is necessary, it will be temporarily <br /> covered with plastic sheeting. Soil stockpiles shall be stabilized from erosion and located away <br /> from storm drain inlets, waterways, and drainage channels. The site will be periodically <br /> sprinkled with water until the surface is wet in order to prevent dust in the air and sediment on <br /> the roadways. <br /> 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. The following relevant BMPs for this project include: <br /> BMP C 120: Temporary and Permanent Seeding <br /> BMP C 121: Mulching <br /> 3.1.7 Element#7—Protect Drain Inlets <br /> All existing and proposed storm drain inlets and culverts made operable during construction that <br /> may receive stormwater on and downstream of the site shall be protected to prevent unfiltered or <br /> untreated water from entering the drainage conveyance system. The following relevant BMPs for <br /> this project include: <br /> BMP C220: Storm Drain Inlet Protection <br /> SNBL USA, LTD—Seaway Commercial Center <br /> SWPPP 6 August, 2022 <br />
