Recycling Treated Wastewater For Industrial Water Use in MN March 15, 2007 Industry Stakeholder Workshop Issues Table Technical Issues Topic Discussion Reliability • Concerned about control of water quality and quantity o Industries perceive they have that control now o Relates to their performance • How will seasonal quantity requirements be addressed? • Expect to have some source as a backup o Maintaining a backup supply has a cost Need to exercise equipment and maintain pipes Maintain intakes and other features Need to account for this in a facility analysis o Will there be permit changes for the backup supply? Could affect both NPDES and Appropriations permits Ex: some permits have flow-based restrictions that will trigger requirements. • If a reclaimed supply is not available and a backup supply must be used and the amount/quality exceeds a permit limit or requirement – who pays the penalty or the extra costs to meet the permit limit (which would not have been incurred if the reclaimed supply had been available)? o If backup supply is used – need to handle two different source waters and the quality differences o Could reduce the storage requirements if another supply is used to augment rather than just backup a reclaimed supply Need to assess the quality issues with a blended supply Need to assess the infrastructure requirements (piping, valving, painting and signage) and costs for a specific application • Reclaimed supply can also be a backup to the main supply (emergency source if the ground or surface water supply has a contamination – comment brought in from March 8 meeting) • Who handles the maintenance, particularly of the transmission mains? Will the municipality have access? ExhB-Issues Tables_frMar1507 Ind Stakeh Mtg-FINAL.doc Page 1 of 7
