Stricter effluent nutrient limits pose a dilemma for clean-water plant teams: How to comply with the new permit, and at what cost?
Major plant upgrades to drive down nitrogen and (especially) phosphorus levels can cost millions of dollars and may be out of reach for facilities serving small communities, especially those with lower-income populations that can’t easily absorb a big rate increase.
Now the U.S. EPA is compiling a study on efficient and cost-effective approaches for nutrient removal, looking to help communities find ways to meet stricter limits without undue financial burden.
