Description of the Regional Inflow/Infiltration (I/1) Program The 2040 Water Resources Policy Plan states tnat the Council will establish 111 goals for all communities discharging wastewater to the MDS. Communities that have excessive 1/1 in their sanitary sewer systems will be required to eliminate excessive 1/I. The Council will continue the implementation of its on-going 1/1 reduction program. Communities identified through the program as needing to eliminate excessive 1/1 will be required to submit a work plan that details work activities to identify and eliminate sources of 1/1. The Council can limit increases in service within those communities having excess 1/1 that do not demonstrate progress in reducing their excess 1/1. The Council will meet with the community and discuss this alternative before it is implemented. It is required that those communities that have been identified as contributors of excessive I/1, and that have not already addressed private property sources, do so as part of their 1/1 program. Significant work has been accomplished on the public infrastructure portion of the wastewater system. The Council will pursue making funds available through the State for 1/1 mitigation, and promote statutes, rules and regulations to encourage 1/1 mitigation. Management of Subsurface Sewage Treatment Systems (SSTS) and Private Systems The Metropolitan Land Planning Act requires the sewer element of the local comprehensive plan to describe the standards and conditions under which the installation of subsurface sewage treatment systems and other private wastewater treatment systems will be permitted and to the extent practicable, the areas not suitable for public or private systems. The appropriate density for development with subsurface sewage treatment systems depends on the suitability of the soils to treat wastewater and whether space is available for a primary and back up drainfield. It is the Council's position that all municipalities and counties allowing subsurface sewage treatment systems should incorporate current MPCA regulations (Minn. Rules Chapter 7080-7083) as part of a program for managing subsurface sewage treatment systems in the sewer element of their local comprehensive plan and implement the standards in issuing permits. Centerville should adopt a management program consistent with state rules. An overview of Centerville's management program must be included in the community's local comprehensive plan update. If adequate information on the management program is not included; the comprehensive plan will be found incomplete for review until the required information is provided to the Council. Specific requirements for the local comprehensive plan can be found in the Local Planning Handbook Small private treatment plants are located throughout the Metropolitan Area serving such developments as individual industries, mobile home parks, and other urban type uses. The Council's position is that such private wastewater treatment plants should be permitted only if they are in areas not programmed for metropolitan sewer service in the future and they are provided for in a community's comprehensive plan that the Council has approved. Furthermore, the community is responsible for permitting all community or cluster wastewater treatment systems consistent with Minnesota Rules Chapter 7080- 7083 and MPCA standards. The Council will not provide financial support to assist communities if these systems fail. Centerville should include in the sewer element of its local comprehensive plan the conditions under which private treatment plants or municipal treatments would be allowed, and include appropriate management techniques sufficiently detailed to ensure that the facilities conform to permit conditions. Centerville is responsible for ensuring that permit conditions for private treatment plants are met and financial resources to manage these facilities are available.
