Index • Overview • Policy and Strategy (Pickart) • Minneapolis Issues (Pickart) • Current Program • I/I Program Update (Colvin) • Grant Program (Willett) • Demand Charge (Willett)
Policy and Strategy • Infiltration/Inflow Program • 2000-2002: Problem identification • 2003-2004: I/I Task Force • 2005: Water Resource Management Policy Plan
Policy and Strategy • Water Resources Management Policy Plan • Infiltration/Inflow Policy • The Council will not provide additional capacity to serve excessive infiltration/inflow (based on design flow standard)
Policy and Strategy • Infiltration/Inflow Program • Communities implement infiltration/inflow reduction programs to achieve compliance with Council design flow standard by 2012 • Starting in 2013, the Council will implement a wastewater demand charge for those communities that have not achieved compliance

Demand Charge = a community-specific charge for excess capacity demand
Background Facts • Required by Water Resources Management Policy Plan (WRMPP)“Starting in 2013, the Council will institute a wastewater rate demand charge program for those communities that have not met their inflow and infiltration goal(s).” (p. 40) • Impacts community I/I efforts now • We said we’d have a public process for developing the Demand Charge details • Minneapolis asked for 3-year notice of how the Demand Charge will work
Development Options • Begin development process now and implement in 2013 • Begin development of charge now but reconsider implementation date • Delay development and implementation Requires changing WRMPP
Develop Demand Charge • Community Task Force? • Develop goals/criteria of charge • Hire consultant • Review similar charges across other metros • Identify feasible designs • Analysis of design • Consider need for legislation
Delay Implementation of Demand Charge • Why? • Success of local programs gives MCES ability to delay • Capital Project decisions for some growth projects are being deferred • Cities are under a lot financial pressure with declining property values and local government aid (from State)
Recommended Next Steps • Establish a Task Force • Begin review of Demand Charge (decision on implementation date can wait)
