Wild rice sulfate rulemaking hearings begin this week

The MPCA began hearings this week on the sulfate water quality standard which will apply to facilities that discharge into “wild rice waters.” Cities located within 25-60 miles upstream of such waters will be evaluated first by the MPCA to determine whether a limit is required. CGMC members on the list include Alexandria, Babbitt, Bagley, Bemidji, Biwabik, Brainerd, Detroit Lakes, Ely, Foley, Hinckley, Hoyt Lakes, Le Sueur (Minnesota River Valley Public Utilities Commission), Plainview, Princeton, Red Wing, Rushford, Sandstone, Staples, Wabasha, Wadena and Winona.
 
Our preliminary analysis demonstrates that future compliance with the sulfate standard could require expensive treatment upgrades such as reverse osmosis, membrane filtration, and/or crystallization and evaporation. These upgrades could cost individual cities $10-$20 million or more, depending upon site-specific information. 
 
We recommend that affected cities participate in the rulemaking process by submitting comments and/or attending a public hearing. Hearings began Oct. 23 in St. Paul, and will be held around the state over the next few weeks. You can find a complete list of hearings here.
 
We are in the process of finalizing our talking points for affected cities and will be circulating those soon. If you would like a copy or have other questions, please email Elizabeth Wefel at eawefel@flaherty-hood.com.
