All discharge points must be adequately protected from erosion and scour. The discharge must <br /> be dispersed over natural rock riprap, sand bags,plastic sheeting or other accepted energy <br /> dissipation measures. Adequate sedimentation control measures are required for discharge water <br /> that contains suspended solids. <br /> (c) Construction Site Waste. <br /> (1) Waste and Material Disposal: All waste, unused building material <br /> (including garbage debris, cleaning wastes, wastewater, toxic materials or <br /> hazardous materials), collected sediment, asphalt and concrete millings, floating <br /> debris,paper,plastic, fabric, construction and demolition debris and other wastes <br /> must be properly contained on site and disposed of off site, not allowed to be <br /> carried by runoff into receiving channel or starage sewer system, �„—� <br /> .,.,� �i.,.�,;��, r�rnr n a;�r,.�.,i ,- � <br /> :r�y ..���� � , <br /> (2) Hazardous Materials: Oil, gasoline,paint and any hazardous substances <br /> must be properly stored, including secondary containment, to prevent spill, leaks <br /> or other discharge. Restricted access to storage areas must be provided to prevent <br /> vandalism. Concrete wash must be limited to a defined area of the site and runoff <br /> must be contained within the defined area. Storage��r�s��of hazardous <br /> waste must be in compliance with MPCA regulations. <br /> (3) Liquid Waste: All non stormwater discharges (concrete truck washout, <br /> vehicle washing, maintenance spills, etc.) conducted during the construction <br /> activity must comply with the newest version of the state NPDES Permit. <br /> (4) Sanitary Facilities; Adequate on-site sanitary facilities shall be provided in <br /> convenient location(s) for all persons who work on the site. <br /> (d) Tracking. Each site shall have graveled roads, access drives and parking areas of <br /> sufficient width and length to prevent sediment from being tracked onto public or private <br /> roadways. Any sediment reaching a public or private road shall be removed by street cleaning <br /> before the end of each workday. <br /> (e) Drain Inlet Protection. All storm drain inlets shall be protected during <br /> construction with control measures as approved by the City. These devices shall remain in place <br /> until final stabilization of the site. A regular inspection and maintenance plan shall be developed <br /> and implemented to assure these devices are operational at all times. <br /> (� Site Erosion Control. <br /> (1) Channelized runoff from adj acent areas passing through the site shall be <br /> diverted around disturbed areas, if practical. Diverted runoff shall be conveyed in <br /> a manner that will not erode the conveyance at receiving channels. All temporary <br /> or permanent drainage channels must be stabilized within 24 hours of being <br /> connected to a Water of the State. Sediment control is required along channel <br /> edges to reduce sediment reaching the channel. <br /> 9 <br />
