x <br /> Stormwater Pollution Prevention Plan <br /> will be controlled where increases in impervious area or soil compaction during construction <br /> could lead to downstream erosion, or where necessary to meet local agency stormwater discharge <br /> requirements. <br /> Construction is to commence and be completed during the dry season and there will be minimal <br /> stormwater discharges from the project site. The amount of exposed soil will also be minimal. <br /> No BMP's for controlling flow rates are proposed at this time. <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 /> All catch basins, existing and proposed, are recommended to have storm drain inlet <br /> protection. In addition, any existing or proposed storm drain within 300 feet of the land <br /> disturbing activity shall have storm drain inlet protection. <br /> Sediment will be removed from paved areas in and adjacent to construction work areas manually <br /> or using mechanical sweepers, as needed,to minimize tracking of sediments on vehicle tires <br /> away from the site and to minimize wash-off of sediments from adjacent streets in runoff. <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 C120: Temporary and Permanent Seeding <br /> BMP C 121: Mulching <br /> BMP C123: Plastic Covering <br /> BMP C 140: Dust Control <br /> In general, cut and fill slopes will be stabilized as soon as possible. If a soil stockpile is <br /> necessary,it will be temporarily covered with plastic sheeting. Soil stockpiles shall be stabilized <br /> from erosion and located away from storm drain inlets,waterways, and drainage channels. The <br /> site will be periodically sprinkled with water until the surface is wet in order to prevent dust in <br /> the air and sediment on 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. Stormwater run-off shall be minimal as construction of the proposed improvements are <br /> to commence and be completed during the dry season.
