backup occurring, or limits the capacity in the system to the point where the Council can no longer provide additional wastewater services. MCES will work with those communities on a case-by-case basis. If at any time the excessive I/I from a community reaches a level that jeopardizes MCES's ability to convey wastewater without an overflow occurring, MCES will notify the community of the problem. If no timely solution can be found then the Council will recommend to the MPCA that no new sanitary sewer extensions should be approved until the issue is resolved There are locations in the MDS where the excessive wet weather flow from several communities is using up the capacity designed for regional growth. But this growth restriction is not always limited to communities that aren't addressing their I/I problem. Other communities served by the same interceptor system that want to grow, and have either no excessive UI or are taking action to eliminate excessive UI, are also having their growth restricted. In these cases, the Council will provide wastewater conveyance facilities to serve both regional growth and to convey excessive I/I in the interim until the tributary communities achieve their I/I/ goals. Wherever possible the investment made to initially convey or treat the excessive UI will be recovered to provide for long-term dry weather capacity for future growth as the excessive I/I is eliminated from the system. ® MCES will work with communities to implement an initial inflow and infiltration reduction program during 2007 through 2011. MCES will estimate the cost of UI reduction to eliminate the sources of excessive peak flows. MCES will allow communities to undertake work to reduce inflow and infiltration using local funds as long_as those funds equal or exceed the estimated cost of I/I reduction. If a communitydoes not voluntarily undertake this work, MCES will add an equivalent surcharge to the community's municipal wastewater charges. ~ ,.r.xe e.,,.e....:, e yr e.,,e_:..,. .x Updated 3/31/2010 934 AM BJP
