• <br />WS — Item 2 <br />WORK SESSION STAFF REPORT <br />Work Session Item <br />Date: July 6, 2010 <br />To: City Council <br />From: Tim Payne, Natural Resources Specialist <br />Re: 2009 Stormwater Pollution Prevention Plan Accomplishments <br />Background <br />In compliance with the provisions of the Clean Water Act, as amended, (33 U.S.C. 1251 <br />et. Seq., 40CFR 122, 123 and 124, as amended et seq.); Minnesota Statutes Chapters 115 <br />and 116, as amended, and Minnesota Rules Chapter 7001, the City of Lino Lakes has <br />adopted a Storm Water Pollution Prevention Plan (SWPPP) and authorized its submittal <br />to the Minnesota Pollution Control Agency as part of the City's application for <br />enrollment in the State of Minnesota's General National Pollution Discharge Elimination <br />System Phase II Permit program. The permit authorizes the City to discharge storm <br />water. An annual public hearing pertaining to the SWPPP was held at an Environmental <br />Board meeting on April 28, 2010. <br />Analysis: <br />According to the 1996 National Water Quality Inventory, stormwater runoff is a leading <br />source of water pollution. Stormwater runoff can harm surface waters such as rivers, <br />lakes, and streams which in turn cause or contribute to water quality standards being <br />exceeded. <br />Stormwater runoff can change natural hydrologic patterns, accelerate stream flows, <br />destroy aquatic habitats, and elevate pollutant concentrations and loadings. Development <br />substantially increases impervious surfaces thereby increasing runoff from city streets, <br />driveways, parking lots, and sidewalks, on which pollutants from human activities settle. <br />Common pollutants in runoff include pesticides, fertilizers, oils, metals, pathogens, salt, <br />sediment, litter and other debris are transported via stomiwater and discharged — <br />untreated — to water resources through storm sewer systems. <br />1 <br />
