BMPs C 151, C 152, C 153, and C 154 will be used to control pollutants. All <br /> pollutants, including waste materials and demolition debris, that occur onsite shall <br /> be handled and disposed of in a manner that does not cause contamination of <br /> stormwater. Good housekeeping and preventative measures will be taken to ensure <br /> that the site will be kept clean,well-organized, and free of debris. <br /> Element#10—Control Dewatering <br /> There will be no dewatering expected as part of this proposal. If it occurs, Baker tanks will <br /> be used for dewatering. <br /> Element#11 —Maintain BMPs <br /> BMPs C150, C160, and C162 shall be used to manage the project. <br /> All temporary and permanent erosion and sediment control BMPs shall be maintained and <br /> repaired as needed to assure continued performance of their intended function. <br /> Maintenance and repair shall be conducted in accordance with each particular BMP's <br /> specifications. Visual monitoring of the BMPs will be conducted at least once every <br /> calendar week and within 24 hours of any rainfall event that causes a discharge from the <br /> site. If the site becomes inactive, and is temporarily stabilized, the inspection frequency <br /> will be reduced to once every month. All temporary erosion and sediment control BMPs <br /> shall be removed within 30 days after the final site stabilization is achieved or after the <br /> temporary BMPs are no longer needed. Trapped sediment shall be removed or stabilized <br /> on site. Disturbed soil resulting from removal of BMPs or vegetation shall be permanently <br /> stabilized. <br /> Element#12—Manage the Proiect <br /> BMPs C150, C160, and C162 shall be used to manage the project. Erosion and sediment <br /> control BMPs for this project have been designed based on the following principles:Design <br /> the project to fit the existing topography, soils, and drainage patterns; Emphasize erosion <br /> control rather than sediment control; Minimize the extent and duration of the area exposed; <br /> Keep runoff velocities low; Retain sediment on site; Thoroughly monitor site and maintain <br /> all ESC measures and Schedule major earthwork during the dry season. The SWPPP shall <br /> be modified as necessary to include additional or modified BMPs designed to correct <br /> problems identified. Revisions to the SWPPP shall be completed within seven (7) days <br /> following the inspection. <br /> Element#13 —Protect On-site Stormwater Management BMPs for Runoff from Roofs <br /> and Other Hard Surfaces <br /> BMPs C233 will be used. On-site stormwater management BMPs used for <br /> runoff from roofs and other hard surfaces include full dispersion, roof <br /> downspout full infiltration or dispersion systems, perforated stubout <br /> connections, rain gardens, bioretention systems, permeable pavement, <br /> sheetflow dispersion, and concentrated flow dispersion.
