Cover stockpiles with plastic sheeting, according to the approved construction plans, as <br />needed to prevent erosion during site grading. Maintain until stockpiles are removed from <br />site. <br />Element #6 — Protect Slopes <br />All cut and fill slopes will be designed, constructed, and protected in a manner than <br />minimizes erosion. The following specific BMPs will be used to protect slopes for this <br />project. <br />Element #7 — Protect Drain Inlets <br />All storm drain inlets and culverts made operable during construction shall be protected to <br />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 <br />wash water separate from entering storm drains until treatment can be provided. <br />Element #8 — Stabilize Channels and Outlets <br />Where site runoff is to be conveyed in channels or discharged to a stream or some other <br />natural drainage point, efforts will be taken to prevent downstream erosion. <br />Element #9 — Control Pollutants <br />All pollutants, including waste materials and demolition debris, that occur onsite <br />shall 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 Dewaterin2 <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 />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 BMPs <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 on <br />site. Disturbed soil resulting from removal of BMPs or vegetation shall be permanently <br />stabilized. <br />Insight Engineering Co. — Stormwater Site Plan 05/31/2022 <br />-16- <br />
