Lower Mississippi River Basin in Minnesota • 7,266 square miles (4,650,100 acres) • All or part of 17 counties • Roughly two-thirds cultivated • Population: 600,000-700,000 concentrated in south Metro. area and around 7 major cities • 39 bacteria-impaired listed reaches in 2004

History • Oct. 2002 – Denial of Contested Case Hearing Request • Nov. 2002 – Approval by USEPA • 2003 – MCEA Challenge of USEPA Approval in Federal District Court • 2003-Present – Implementation Plan Development and On-Going Fecal Coliform Reduction Efforts • June 2005 – District Court Order • July-Oct. 2005 – Revisions and Public Notice

District Court Order • The revised TMDL shall be established at a level necessary to implement the applicable water quality standards for each reach impaired with fecal coliform contamination. • The revised TMDL shall contain a margin of safety that accounts for lack of knowledge concerning the relationship between effluent limitations and water quality.

District Court Order (cont.) • The revised TMDL shall properly account for straight pipe septic systems in the wasteload allocation of the TMDL. • The State of Minnesota is allowed 90 days from the date of entry of final judgment in this case to give pubic notice and to seek comment on, a proposed amended or replacement Regional TMDL …….

District Court Order (cont.) • The existing southeastern TMDL shall remain in force and effect pending completion of the recalculated TMDL.

Required Useful • Loading capacity • Documentation of use (TMDL) for each listed • Clear presentation of reach magnitude and distribution • Wasteload allocation (spatial and temporal) of impairments • Load Allocation • Source inventory • Margin of Safety • Linkage between source inventory and in-stream water quality • Adaptive and multiple benefit approach to implementation
