Water Quality Standards

MESERB works to ensure that water quality standards that impact municipal wastewater facilities are based on open and transparent science, independently reviewed and result in meaningful benefits to water quality. Water quality standards issues that MESERB is currently focused on include:

  • Wild Rice Sulfate
  • Chloride (and other salty parameters)
  • Total Nitrogen Standard
  • Mercury
  • River and Lake Euthrophication Standards
  • Antidegradation

Innovative Approaches to NPDES Permitting

MESERB is always looking for innovate implementation methods to address water quality regulations to achieve maximum environmental benefit while responsibly utilizing state and local resources. Such activities include:

  • Water Quality Trading – Working to research and develop a more flexible trading framework including point to non-point trading.
  • Integrative Planning – Working to develop a framework that allows municipalities to meet regulatory obligations while optimizing infrastructure investments through prioritization and sequencing of work.
  • Plant Optimization – Working with members to identify, develop and share plant optimization techniques and technologies to maximize efficiency in existing infrastructure.
