v. Use of a sedimentation bag with discharge to a ditch or swale for small <br /> volumes of localized dewatering. <br /> d. Permittees must handle highly turbid or contaminated dewatering water <br /> separately from stormwater. <br /> 11. Maintain BMPs <br /> a. Permittees must maintain and repair all temporary and permanent erosion and <br /> sediment control BMPs as needed to assure continued performance of their <br /> intended function in accordance with BMP specifications. <br /> b. Permittees must remove all temporary erosion and sediment control BMPs <br /> within 30 days after achieving final site stabilization or after the temporary <br /> BMPs are no longer needed. <br /> 12. Manage the Project <br /> a. Phase development projects to the maximum degree practicable and take into <br /> account seasonal work limitations. <br /> b. Inspection and monitoring—Inspect,maintain and repair all BMPs as needed to <br /> assure continued performance of their intended function. Conduct site <br /> inspections and monitoring in accordance with Special Condition S4. <br /> c. Maintaining an updated construction SWPPP—Maintain,update,and <br /> implement the SWPPP in accordance with Special Conditions S3, S4 and S9. <br /> 13. Protect Low Impact Development(LID) BMPs <br /> The primary purpose of LID BMPs/On-site LID Stormwater Management BMPs is <br /> to reduce the disruption of the natural site hydrology. LID BMPs are permanent <br /> facilities. <br /> a. Permittees must protect all Bioretention and Rain Garden facilities from <br /> sedimentation through installation and maintenance of erosion and sediment <br /> control BMPs on portions of the site that drain into the Bioretention and/or Rain <br /> Garden facilities. Restore the facilities to their fully functioning condition if <br /> they accumulate sediment during construction. Restoring the facility must <br /> include removal of sediment and any sediment-laden Bioretention/Rain Garden <br /> soils,and replacing the removed soils with soils meeting the design <br /> specification. <br /> b. Permittees must maintain the infiltration capabilities of Bioretention and Rain <br /> Garden facilities by protecting against compaction by construction equipment <br /> and foot traffic. Protect completed lawn and landscaped areas from compaction <br /> due to construction equipment. <br /> c. Permittees must control erosion and avoid introducing sediment from <br /> surrounding land uses onto permeable pavements.
