These meetings were used to gain input on the state agency setting for wastewater recycling, how these practices are handled now, and any plans for the future. Two meetings were held with industrial representatives. A total of 11 industries participated in the workshops with 15 representatives attending. A range of industry sectors and business sizes were represented. Table 4.1 lists the industries attending the two workshops. Table 4.1.

Followup discussions focused on project elements for demonstration projects and any issues the industry might have if looking to site a new facility. The discussion of issues was segmented into technical issues and institutional issues. In some cases, issues overlapped these general categories. Metropolitan Council Environmental Services 57
Section 4: Implementation Considerations Recycling Treated Municipal Wastewater for Industrial Water Use The third forum brought together a full spectrum of stakeholders: the same regulatory agencies, two industries from the previous meetings (CertainTeed Corporation and Marathon Petroleum), a cross-sector group (Minnesota Environmental Initiative), wastewater utilities (Mankato and Met Council), and water utilities (represented by the Water Utility Council of Minnesota). This group reviewed the outcomes of the previous stakeholder meetings and discussed next steps to promote wastewater recycling on a broader scale in Minnesota. Outcomes The implementation issues identified in the stakeholder meetings generally fit into one of the four focus areas listed in Figure 4.1. Key points for each focus area are presented below. Environmental Need & Stewardship Minnesota’s commitment to natural resources protection can serve as a catalyst for recycling treated municipal wastewater practices. Regulations The regulatory requirements and permitting process should encourage industries and municipalities to pursue recycling treated municipal wastewater. Figure 4.1. Implementation Issue Focus Areas Environmental Stewartship Incentives & Risk Regulations Data Collection & Research Need Water supply shortages and watershed water quality issues occur in Minnesota and have been the driver for recycling treated municipal wastewater applications in areas where thresholds were reached with few options. The state needs to be prepared for an increase in water issues that can be solved with recycling treated municipal wastewater applications. A vision for wastewater and water supply systems in Minnesota beyond the typical 20-year planning cycle is needed – looking to Minnesota’s long-term economic vitality and quality of life. Stewardship Water conservation awareness in Minnesota is increasing and many industries are adopting water protection measures. Industries recognize that recycling treated municipal wastewater can be of benefit to their business and the community. Recycling treated municipal wastewater practices can build on this awareness. A positive image for recycling treated municipal wastewater needs to be established: it protects Minnesota’s water resources and it is a safe supply. Customers and suppliers will be less likely to engage in recycling treated municipal wastewater projects if there will be resistance from the community. Wastewater recycling needs to move from an unknown to a positive image. Current regulations: MN handles recycling treated municipal wastewater applications on a case-by-case basis using the California Water Recycling Criteria. This approach matches the demand. Municipalities and industries identified several permit-related issues that without resolution early in the planning process would deter them from recycling treated municipal wastewater. Existing regulatory requirements for wastewater facility planning to include wastewater recycling alternatives needs to be enforced and linked to water supply studies. There currently is not a demand for recycled wastewater that requires investment in water regulation development. However, without resolution of some issues, it may inhibit the planning for recycling treated municipal wastewater practices that should be occurring for long-term sustainability of Minnesota’s water resources. 58 Metropolitan Council Environmental Services

<strong>Recycling</strong> <strong>Treated</strong> <strong>Municipal</strong> <strong>Wastewater</strong> <strong>for</strong> <strong>Industrial</strong> <strong>Water</strong> <strong>Use</strong><br />
Minnesota’s industrial water demand can be supplied in many areas by recycled municipal wastewater.<br />
Treatment technologies are available to meet the highest levels of water quality required by industries and<br />
protect public health. In some cases, recycled wastewater is a cost-competitive supply to traditional water<br />
sources. A remaining area to consider is what issues need to be addressed to implement recycled<br />
wastewater projects in Minnesota.<br />
4.1 Overview<br />
In addition to technical issues, there are regulatory, legal, and institutional issues such as funding and<br />
fees, agency jurisdictions, ordinances, and public involvement that must be addressed to successfully<br />
implement wastewater recycling programs. Implementation issues associated with the development of<br />
wastewater recycling programs in other states and specific research on the topic has provided a base of<br />
knowledge <strong>for</strong> Minnesota to draw upon. However, because each state has its own regulatory program <strong>for</strong><br />
recycled wastewater, as well as other environmental permitting practices and government structures, a<br />
complete list of issues will contain some that are state-specific. To begin to address the many facets of<br />
implementing wastewater recycled projects in Minnesota, a series of stakeholder meetings were held.<br />

now, and any plans <strong>for</strong> the future.<br />
