Minnesota Water Quality Rules - Amendments To 7050 and 7052

The Minnesota Pollution Control Agency (MPCA) is requesting comments on its planned amendments to rules governing state water quality standards found in Minnesota Rules Chapters. 7050 and 7052.

Chapter 7050 includes provisions to protect Minnesota’s waters from pollution – including classification system for both surface and ground waters, listing of specifically classified water bodies, water quality standards, nondegradation (antidegradation) provisions, and methods for the determination of site-specific criteria.

Chapter 7052 provides standards specific to surface waters of the state in the Lake Superior Basin - establishes aquatic life, human health, and wildlife water quality standards and criteria for Great Lakes Initiative pollutants, nondegradation standards, and implementation procedures for deriving effluent limitations from these standards and criteria.

The Federal Clean Water Act (CWA) requires States to review their water quality standards every three years (“Triennial Review”) and to amend and update them if necessary. The MPCA initiated this triennial review by seeking comments in a Request for Comments published in the July 28, 2008, State Register.
