City of Orono <br />Surface Water Management Plan February 2019 25 <br />Orono, are summarized in Table 2.3. Mapping of impaired waters is also depicted on <br />Figure 7 <br />Goal <br />4.2G Develop and implement practices as necessary to reduce pollutant loads for waters that <br />do not meet Total Maximum Daily Loads (TMDLs) as approved by the EPA. <br />Coordinate City efforts with applicable Implementation Plans as approved by the <br />Minnesota Pollution Control Agency. <br />Policies <br />4.2.1P Reduce pollutant loading to Impaired Waters in order to restore water quality to State <br />standards. <br />4.2.2P Promote education regarding the benefits of pollutant load reduction. <br />Implementation Strategies <br />4.2.1S The City adopts the completed TMDLs and Implementation Plans into this plan by <br />reference and as listed below. This plan will also be updated to incorporate any <br />TMDLs approved in the future. <br />-Minnesota State Mercury TMDL and Implementation Plan <br />-Twin Cities Metropolitan Area Chloride TMDL and Implementation Plan <br />-Upper Minnehaha Creek Watershed Nutrient and Bacteria TMDL and <br />Implementation Plan <br />Refer to individual TMDLs for more detailed information regarding allocations and <br />required reductions. Management of Waste Load Allocations assigned in TMDLs will <br />be provided through the City’s SWPPP in accordance with MS4 Permit requirements. <br />4.2.2S Goals, policies and implementation strategies for Impaired Waters will be incorporated <br />into the education programs identified in the City’s SWPPP. <br />4.3 Urban Stormwater Management <br />Issues <br />4.3I Land development substantially increases the rate and volume of surface water runoff <br />due to the increase in impervious surfaces. Unmanaged runoff increases sedimentation, <br />pollution, erosion, and flooding downstream and decreases groundwater recharge. <br />Goal <br />4.3G Minimize and mitigate the impacts of urban stormwater runoff on water resources. <br />Policies <br />4.3.1P Continue to administer and maintain the National Pollutant Discharge Elimination <br />System (NPDES) requirements as they apply to the City of Orono. <br />4.3.2P Apply regulatory standards that help the City meet its goal for Urban Stormwater <br />Management. <br />4.3.3P Prioritize potential stormwater management projects that will decrease local runoff <br />rates and volumes and improve water quality.
