Via the Minnesota Pollution Control Agency:
The 2020-2021 triennial standards review of Minnesota’s water quality standards is underway.
The review is an opportunity for the public to provide input on the need for changes to Minnesota’s water quality standards – either new standards or revisions to existing standards. The federal Clean Water Act requires that states review their standards every three years and amend and update them if necessary. (Note: Rulemaking to implement revisions to state water quality standards is conducted separately from the triennial review.)
All parts of Minnesota Rules chapters 7050 and 7052 are open for the public’s review and comment.
Chapter 7050 includes provisions to protect Minnesota’s waters from pollution, including:
- A classification system of designated beneficial uses for both surface water and groundwater (e.g., drinking water, aquatic life and recreation, etc.), and a listing of specifically classified water bodies.
- Numeric and narrative water quality standards that protect these beneficial uses.
- Antidegradation provisions.
- Provisions for the protection of wetlands.
- Methods for the determination of site-specific criteria for toxic pollutants.
- Other provisions related to the protection of surface water and groundwater from point and nonpoint source pollution.
Chapter 7052 provides standards specific to surface waters in the Lake Superior Basin. Chapter 7052 establishes aquatic life, human health, and wildlife water quality standards and criteria based on the EPA’s Great Lakes Initiative, anti-degradation standards and procedures for deriving effluent limitations from these standards and criteria.
Minn. rules also include procedures and requirements for issuing variances to state water quality standards. During the triennial review, the public may comment upon active variances that have been granted by the MPCA.
In addition, the MPCA requests information and opinion from the public on modified Class 2 and Class 7 water bodies (a.k.a., limited resource value waters) that may be able to attain higher use classes.
Details about the subjects open for comment are available below:
- Proposed water quality standards work plan for 2021-2023
- Other potential WQS projects considered by MPCA
- Review of modified Class 2 and Class 7 waters
- Current EPA ambient water quality criteria for developing WQS
- MN Rules Chapters 7050 and 7052
- Variances
- Staff contacts
