committed to the goal of no adverse impact (nondegradation goal) for area water resources. Actions should include: i. Adopting erosion and sediment control ordinances that are consistent with NPDES Construction Stormwater permit and MS4 permit requirements where applicable ii. Preparing wetland management plans (refer to 8G for more details of what should be in a wetland management plan) iii. Adopting ordinances that control peak runoff iv. Including funding mechanisms that support implementation and enforcement 6. Assessment of problems and corrective actions for problems identified A. All communities need to assess the water quality and quantity related problems in their community,prioritize the problems and include actions to adequately solve the problems that were identified. B. All communities must acknowledge and list any impaired waters within their jurisdiction as shown on the current MPCA 303d Impaired Waters list. A TMDL is a calculation that determines the allowable pollutant load that can be discharged into the impaired water such that the water is not impaired. A community that discharges water to an impaired waterbody within or adjacent to the community, needs to explain how and if it intends to be involved with the development of the Total Maximum Daily Load (TMDL) study. i. If a TMDL study is not completed, the city should identify the priority it places on addressing impaired waters and how the city intends to participate in the development or implementation of TMDL studies. ii. If the city is not directly involved in the TMDL study,the city should show how it intends to implement the study findings once the study is completed by the responsible party. iii. If a TMDL study is completed for the impaired water,the community needs to include an implementation strategy including funding mechanisms that will allow them to carry out the TMDL requirements. More information on the MPCA's TMDL program can be found on the MPCA's web site at http://www.pca.state.mn.us/water/tmdl/index html. 7. Financial considerations A. All communities need to include a 5-year CIP that includes funds to solve the problems identified in number 6 above. � B. All communities need to include funding in their CIP or operating budget for ongoing maintenance of their stormwater infrastructure. 8. Implementation priorities and pro�ram A. Developed, developing and any MS4 communities in the rural planning area need to provide information on how they intend to manage stormwater: i. Include an erosion and sediment control ordinance consistent with NPDES Construction Stormwater permit and MS4 permit requirements ii. Identify ways to control runoff rates (subgested guidance - Minnesota Stormwater Manual) so that land-altering activities do not increase peak stormwater flow from the site for a 24-hour precipitation event with a return frequency of 1 or 2, l 0, and l 00 years. 85
