Figure 14 displays the impaired waters <br />map and Table 5 summarizes each of the water body impairments. Section 303(d) of the <br />Federal Clean Water Act (CWA) requires that states establish total maximum daily loads <br />(TMDLs) of pollutants to water bodies that do not meet water quality standards. Each TMDL <br />includes an implementation plan that establishes a list of actions that will be needed to <br />manage the pollutant(s) with the goal of eliminating the impairment. For more information <br />about impaired waters and TMDLs see www.pca.state.mn.us /. <br />Table 5 <br />Impaired Water Bodies Summary <br />Name <br />Year Listed as <br />Affected <br />Pollutant or Stressor <br />Approved <br />Impaired <br />Designated Use <br />TMDL <br />Little Johanna <br />2012 <br />Aquatic <br />Perfluorooctane Sulfonate <br />NA <br />Consumption <br />(PFOS) in Fish Tissue <br />Little Johanna <br />2004 <br />Aquatic recreation <br />NutrienUEutrophication <br />Target Start Date <br />Biological Indicators <br />—2012 <br />Bennett <br />2006 <br />Aquatic recreation <br />NutrienUEutrophication <br />Target Start Date <br />Biological Indicators <br />—2012 <br />Bennett' <br />2012 <br />Aquatic <br />Mercury in Fish Tissue <br />2008 <br />Consumption <br />McCarron <br />2010 <br />Aquatic <br />Mercury in Fish Tissue <br />2008 <br />Consumption <br />Owasso <br />1998 <br />Aquatic <br />Mercury in Fish Tissue <br />2008 <br />Consumption <br />Josephine <br />1998 <br />Aquatic <br />Mercury in Fish Tissue <br />2008 <br />Consumption <br />(1) New listing from draft 2012 Impaired Waters List <br />2.5.2 Floodplains <br />Areas of Roseville prone to larger regional flooding near surface water sources have been <br />identified and mapped by the Federal Emergency Management Agency (FEMA) through the <br />National Flood Insurance Program (NFIP). Flood Insurance Rate Maps (FIRMs) for the City <br />of Roseville were recently published on June 6'", 2010. Figure 14 displays the special flood <br />hazard areas mapped by FEMA. <br />While the 1 percent chance flood hazard areas (Zones A and AE) are mapped in Figure 14, it <br />is important to recognize that the areas designated as Zone X (the remaining portions of the <br />City) may still have potential for flooding. <br />Comprehensive Surface Water Management Plan ROSEV120222 <br />City of Roseville Page 10 <br />
