Introductions – Deborah Manning opened 2. Meeting Focus – Deborah Manning General reuse of treated wastewater effluent. Broaden the topic from the kickoff meeting which had a focus toward industrial reuse applications. Also need to consider reuse in terms of ‘water supply’, not just as a wastewater discharge option. 3. Recap of Treated Municipal Wastewater Reuse Applications in Minnesota List of 7 facilities (handout) o To add: the EPA permitted facility for the Shakopee Mdewakanton Sioux Community, 0.639 mgd Membrane filtration with UV disinfection Discharge permitted to a wetland that is used to irrigate the community’s golf course o Noted that the list does not include agricultural irrigation practices; these facilities all have a beneficial end use other than as a discharge for treated wastewater (there are facilities in MN that land discharge, such as with rapid infiltration basins (RIBs) or to wetlands, which can be considered reuse applications).

MCES Recycling Treated Wastewater for Industrial Reuse Project Meeting Summary Meeting: Municipal Wastewater Reuse Regulatory Stakeholder Group Meeting No.: ME02 Date: 6/12/06 Location: 390 Robert Street, Rm B Lower Level Time: 2:00 – 3:30 PM Drivers – main driver for those on list was to find a suitable discharge for the wastewater; only the Mankato facility had ‘water supply’ as the primary driver, where Calpine Corporation needed cooling water for their new energy facility. Agency/Institution Roles o Draft Table – Handout Lists Agency, Mission/Goals, Role with Wastewater Reuse, Jurisdiction, Approach to Reuse, Issues Reviewed list and noted other items, such as: • MPCA: Under Approach to Reuse – note that MN uses the California Recycling Criteria as basis of water quality criteria used in NPDES permit; also require under MN Rules that planning (facility plans) for all treatment facilities must evaluate reuse alternatives. • MDNR: Noted that there would not be an appropriation fee to ‘reuse’ water for most applications. Gray area is with aquifer recharge applications, where water is reused later by multiple users. • MDH: noted that MDH would be involved for issues related to human exposure. 4. Fostering Wastewater Reuse in Minnesota Open discussion on this issue. Miscellaneous comments provided below. Groundwater recharge/irrigation o Groundwater recharge, whether by irrigation or more direct practices, will benefit local aquifers o MDH must balance recharge need with source protection; issues arisen historically in the state Concern with stormwater basins in wellhead areas o Issues with agricultural irrigation – wells high in nitrates o Mechanism to reduce transfer of water outside of local watershed. Reuse topic has come up at the Metro Area Water Supply meetings (MCES Regional Water Supply Assessment Project). o Some stakeholders are knowledgeable in this area. o See as a water supply solution. o Also discussed as a ‘redundant’ supply option. 5. Public Perception No public comments related to health concerns or water quality issues with existing reuse projects (through permit process).
