Metropolitan Council 2030 Water Resources Management Policv Plan Orono's 2009 Local Surface Water Management Plan will be submitted to Metropolitan Council for its review concurrent with the review by the Minnehaha Creek Watershed District. According to Metropolitan Council, failure to have an updated local surface water management plan consistent with the requirements found in Appendix B-2 of the Council's 2030 Water Resources Management Policy Plan will result in a metropolitan system impact. Metropolitan Council has expanded the content required by statute. This expanded content is provided in Appendix B-2 of the Water Resources Management Policy Plan and is summarized here: • A strong policy statement toward nondegradation of surface water resources. • Adopting official controls that control peak runoff rates (for the 2, 10, and 100-year rainfall events) and lead to total suspended solids and total phosphorus reductions of 80% and 50%, respectively. • Preparing wetland management plans. • Including funding mechanisms that support implementation and enfarcement. • Integration of Orono's National Pollutant Discharge Elimination System � (NPDES) Municipal Separate Storm Sewer System (MS4) permit into this Local Surface Water Management Plan. • Assessment of issues and corrective actions and Orono's actions to assist in solving the issues identified. • Acknowledgement of impaired waters to which the City drains and the City's perceived role in future Total Maximum Daily Loads (TMDLs). • A capital improvement plan that relates to the issues and corrective actions. • An erosion and sediment control ordinance consistent with requirements in the National Pollutant Discharge Elimination System (NPDES) Stormwater Construction Permit. • Require infiltration of the first '/�-inch of runoff of impervious surfaces where soils lend themselves to this practice. � The synopsis of additional requirements picks those that Orono's Local Surface Water Management Plan addresses most directly. Other requirements from Metropolitan Council's guidance are addressed more specifically in 2009 Local Surface Water Management Plan document, which is separate from the Comprehensive Plan.
