pumping must be treated by temporary sedimentation basins, geotextile filters, grit <br />chambers, sand filters, up-flow chambers, hydro-cyclones, swirl concentrators or other <br />appropriate controls as appropriate. Water may not be discharged in a manner that causes <br />erosion or flooding of the site or receiving channels or a wetland. <br />P.) All storm drain inlets must be protected during construction until control measures <br />are in place with either silt fence or an equivalent barrier that meets accepted design <br />criteria, standards and specifications contained in the latest version of the Minnesota <br />Pollution Control Agency's publication, "Protecting Water Quality in Urban Areas." <br />Q.) Catch basins. All newly installed and rehabilitated catch basins must be provided <br />with a sump area for collecting coarse-grained material. Such basins must be cleaned when <br />they are half filled with material. <br />R.) Roof drain leaders. All newly constructed and reconstructed buildings must route roof <br />drain leaders to pervious areas (not natural wetlands) where the runoff can infiltrate. The <br />flow rate of water exiting the leaders shall be controlled so that no erosion occurs in the <br />pervious areas. <br />S.) Follow-up inspections must be performed by the city on a regular basis to ensure that <br />erosion and sediment control measures are properly installed and maintained. In all cases <br />the inspectors will attempt to work with the builder or developer to maintain proper erosion <br />and sediment control at all sites. In cases where cooperation is withheld, construction stop <br />orders may be issued by the city, until erosion and sediment control measures meet <br />Specifications. A second erosion and sediment controUgrading inspection must then be <br />scheduled and passed before the final inspection will be done. <br />T.) Inspection and maintenance. All storm water pollution control management facilities <br />must be designed to minimize the need of maintenance, to provide easy vehicle and <br />personnel access for maintenance purposes and be structurally sound. These facilities must <br />have a plan of operation and maintenance that ensures continued effective removal of the <br />pollutants carried in storm water runoff. The city or its designated representative shall <br />inspect all storm water management facilities during construction, during the first year of <br />operation and at least once every five (5) years thereafter. The city will keep all inspection <br />records on file for a period of six (6) years. It shall be the responsibility of the applicant to <br />obtain any necessary easements or other property interests to allow access to the storm <br />water management facilities for inspection and maintenance purpose. <br />6.5 Permanent Storm Water Pollution Controls. <br />A.) The applicant shall install or construct, or pay the city fees for all storm water <br />management facilities necessary to manage increased runoff, so that the two (2) year, ten <br />(10) year, and one hundred (100) year storm peak discharge rates existing before the <br />proposed development must not be increased. Also accelerated channel erosion must not <br />occur as a result of the proposed land disturbing or development activity. An applicant may <br />12 <br />
