Oil and Grease Control <br /> The first%"runoff shall be treated us'ng oil and grease removal technology. <br /> The proposed redevelopment consists •f a building and contains no parking areas. Therefore,oil <br /> &grease control is expected to be is•I'si al and no oil&grease controls are proposed for this <br /> project. <br /> Outlets <br /> Discharges from the site must have a stable outlet capable of carrying the designed flow at a <br /> non-erosive velocity. <br /> The proposed swales are designed for a 10& 100 year storm events and are capable of carrying <br /> the designed flow at a non-erosive velo ity.The ditch velocity calculations are included as <br /> Exhibit#3. <br /> Thermal Control <br /> The stormwater management plan shall include provisions and practices to reduce the <br /> temperature of runoff for sites located within the watershed of a river or stream identified by <br /> the Wisconsin DNR as a cold water community. <br /> The bio-retention device will provide thermal control for the site. <br /> If the documents are satisfactory,please approve the project for erosion control and storm water <br /> management permits.
