<br />chambers, hydro-calcines, swirl concentrators or other controls as <br />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 /> <br />Subd.3. Waste and Material Disposal. All waste and unused building materials <br />(including garbage, debris, cleaning wastes, wastewater, toxic materials <br />or hazardous materials) shall be properly disposed of off-site and not <br />allowed to be carried by runoff into a receiving channel or storm sewer <br />system.. <br /> <br />Subd. 4. Tracking. Each site shall have graveled roads, access drives and <br />parking areas of sufficient width and length to prevent sediment from <br />being tracked onto public or private roadways. Any sediment reaching <br />a public or private road shall be removed by street cleaning (not <br />flushing) before the end of each workday. <br /> <br />Subd.5. Drain Inlet Protection. All storm drain outlets shall be protected during <br />construction until control measures are in place with a straw bales, silt <br />fence, or equivalent barrier meeting accepted design criteria, standards <br />and specifications contained in the Minnesota Pollution Control Agency <br />publication, "Protecting Water Quality in Urban Areas." <br /> <br />Subd.6. Site Erosion Control. The requirements of this subdivision apply only to <br />construction activities that result in runoff leaving the site. <br /> <br />(a.) Channelized runoff from adjacent areas passing through the site <br />shall be diverted around disturbed areas, if practical. Otherwise, <br />the channel shall be protected as described below. Sheetflow <br />runoff from adjacent areas greater than 10,000 square feet in an <br />area shall also be diverted around disturbed areas, unless shown to <br />have resultant runoff velocity of less than 0.5 foot per second <br />across the disturbed area for the one year storm. Diverted runoff <br />shall be conveyed in a manner that will not erode the conveyance <br />and receiving channels. <br /> <br />(b.) All activities on the site shall be conducted in a logical sequence to <br />minimize the area pf bare soil exposed at anyone time. <br /> <br />(c.) Runoff from the entire disturbed area on the site shall be controlled <br />by meeting either following subsections. <br /> <br />1. All disturbed ground left inactive for 14 or more days <br />shall be stabilized by seeding or sodding (only available <br />prior to September 15) or by mulching or covering or <br />other equivalent control measure. <br />
