Lo <br /> <br />1.) If for any reason a soil stockpile of any size is located closer than <br /> twenty-five (25) feet from a road, drainage channel or storm water <br /> inlet, and will be left for more than seven (7) days, it must be covered <br /> with tm'ps or contrqlled in some other manner <br /> <br />Ali sand, gravel or other mining operations taking place on the development <br />site shall have a National Pollutant Discharge Elimination System General <br />Storm Water permit for industrial activities and all required Minnesota <br />Department of Natural Resources permits. <br /> <br />Temporary rock construction entrances are not required in Ramsey. The <br />contractor is required to use a pickup type sweeper on adjacent streets daily <br />during active construction or as directed by the City. <br /> <br />Parking is prohibited on ail bare lots and all temporary construction <br />entrances, except where street parking is not available. Gravel entrances are <br />to be used for deliveries only as per the development contract. <br /> <br />Streets must be cleaned and swept whenever tracking of sediments occurs <br />and before sites are left idle for weekends and holidays. Establishment of a <br />regular sweeping schedule is encouraged. <br /> <br />Water (impacted by the construction activity) removed from the site by <br />pumping must be treated by temporary sedimentation basins, geotextile <br />filters, grit chambers, sand filters, up-flow chambers, hydro-cyclones, swirl <br />concentrators or other appropriate controls. Such water shall not be <br />discharged in a manner that causes erosion or flooding of the site, receiving <br />channels, adjacent property or a wetland. <br /> <br />Ali storm drain inlets must be protected during construction until control <br />measures are in place with either silt fence or an equivalent barrier that <br />meets accepted design criteria, standards and specifications as contained in <br />the latest version of the Minnesota Pollution Control Agency's publication, <br />"Protecting Water Quality in Urban Areas." <br /> <br />Roof drain leaders. All newly constructed and reconstructed buildings must <br />route roof drain leaders to pervious areas (not natural wetlands) where the <br />runoff can infiltrate. The discharge rate shall be controlled so that no erosion <br />occurs in the pervious areas. <br /> <br />Follow-up inspections must be performed by the city on a regular basis to <br />ensure that erosion and sediment control measures are properly installed and <br />maintained.
