Recycling Treated Wastewater For Industrial Water Use in Minnesota MCES Project 070186 / LCMR 05-07d 4/24/07 Water Reuse for Minnesota Industries – Implementation Considerations Discussion with Stakeholders, April 24, 2007 Topic Key Points Potential Actions Environmental Stewardship Regulatory Leadership • Water reuse for many industries will be driven by their commitment to sustainable resources. • Approval and Permitting Process: The regulatory requirements and permitting process should encourage industries and municipalities to pursue water reuse. • Water Reuse Image: Recognition that this is a practice the state encourages for water resource protection. • Watershed Transfer of Pollutants: Address pollutant transfer in the TMDL process and NPDES permitting. • Appropriations Permit: Clarify the need for a DNR Appropriations Permit. Liability • Industries need to be assured they are not taking on undue liability with the use of a reclaimed supply. There is concern for facility damages/loss of production, permit violations, and health problems associated with using a reclaimed supply. • Establish an award program for water reuse. • Evaluate existing award programs and how water reuse practices would fit under these programs. • Support a public education/outreach effort linking water reuse to environmental stewardship and sustainability. • Establish a regulatory ‘water reuse group’ with individuals as the key point of contact for each agency involved in establishing a permit to provide and use a reclaimed water supply. • The water reuse group or a subcommittee will engage in a partnered project that recommends regulatory topics for further evaluation. • Provide fact sheets and other guidance documents for municipalities and industries to reference as they consider water reuse applications, to include: o Related permits required o State agency approvals required • Other information as deemed necessary • Establish a group or fund a project to resolve the liability and indemnification issues of water reuse applications.
