and downslope sides of the site. If a channel or area of concentrated • <br /> runoff passes through the site, silt fences shall be placed along the channel <br /> edges to reduce sediment reaching the channel. The use of silt fences, <br /> straw bales, or equivalent control measure must include a maintenance and <br /> inspection schedule. <br /> (d) If remaining for more than seven days, they shall be stabilized by mulching, <br /> vegetative cover, tarps or other means. Erosion from piles which will be in <br /> existence for less than seven days shall be controlled by placing straw bales or silt <br /> fence barriers around the pile. In-street utility repair or construction soil or dirt <br /> storage piles located closer than 25 feet of a roadway or drainage channel must be <br /> covered with tarps or suitable alternative control, if exposed for more than seven <br /> days, and the storm drain inlets must be protected with straw bale or other <br /> appropriate filtering barriers. <br /> Subd. 7.
