<br />Page 15 of26 <br />Pennit No: MN RlO0001 <br /> <br />3. The timing of the installation of sediment control practices may be adjusted to accommodate <br />short-teml activities such as clearing or grubbing, or passage of vehicles. Any short-tenn activity <br />must be completed as quickly as possible and the sediment control practices must be installed <br />immediately after the activity is completed. However, sediment control practices must be <br />installed before the next precipitation event even if the activity is not complete. <br /> <br />4. All stonn drain inlets must be protected by appropriate BMPs during construction until all <br />sources with potential for discharging to the inlet have been stabilized. <br /> <br />5. Temporary soil stockpiles must have silt fence or other effective sediment controls, and <br />cannot be placed in surface waters, including storm water conveyances such as curb and gutter <br />systems, or conduits and ditches. <br /> <br />6. Vehicle tracking of sediment from the construction site must be minimized by BMPs such as <br />stone pads, concrete or steel wash racks, or equivalent systems. Street sweeping must be used if <br />such BMPs are not adequate to prevent sediment from being tracked onto the street (see Part <br />1V.E.4.d.). <br /> <br />7. The Permittee must install temporary sedimentation basins as required in Part III.B. of this <br />pennit. <br /> <br />D. DEWATERING AND BASIN DRAINING <br /> <br />1. Dewatering or basin draining (e.g., pumped discharges, trench/ditch cuts for drainage) related to <br />the construction activity that may have turbid or sediment laden discharge water must be <br />discharged to a temporary or pennanent sedimentation basin on the project site whenever <br />possible. If the water call110t be discharged to a sedimentation basin prior to entering the surface <br />water, it must be treated with the appropriate BMPs, such that the discharge does not adversely' <br />affect the receiving water or downstream landowners. The Permittee(s) must ensure that <br />discharge points are adequately protected from erosion and scour. The discharge must be <br />dispersed over natural rock riprap, sand bags, plastic sheeting or other accepted energy <br />dissipation measures. Adequate sedimentation control measures are required for discharge <br />water that contains suspended solids. <br /> <br />2. All water from dewatering or basin draining activities must be discharged in a ma1111er that does <br />not cause nuisance conditions, erosion in receiving channels or on downslope properties, or <br />inundation in wetlands causing significant adverse impact to the wetland. <br /> <br />E. 1NSPECTIONS AND MAINTENANCE <br /> <br />1. The Permittee(s) (either the owner or operator, whoever is identified in the SWPPP) must <br />routinely inspect the construction site once every seven (7) days during active construction and <br />within 24 hours after a rainfall event greater than 0.5 inches in 24 hours. <br /> <br />2. All inspections and maintenance conducted during construction must be recorded in writing and <br />these records must be retained with the SWPPP in accordance with Part IIID. Records of each <br />inspection and maintenance activity shall include: <br /> <br />a. Date and time of inspections; <br /> <br />wq-strm2-51 <br />
