The documents below provide information about water and water-quality issues in Minnesota.
Permit forms and fact sheets
MPCA water quality permits establish specific limits and requirements to protect Minnesota's surface and groundwater quality for a variety of uses, including drinking water, fishing and recreation. Permits are regularly reviewed and updated as they expire, allowing the MPCA to incorporate new information about the impacts of pollutants to the environment in subsequent permits. Permits are enforced through a combination of self-reporting (reports to the MPCA, U.S. EPA or both) and compliance monitoring.

- Continuing Planning Process - State of Minnesota's Water Quality Management Program Section 303(e) of the federal Clean Water Act (CWA) requires each state to produce a Continuing Planning Process document describing the processes and procedures it uses in water quality planning. The objective of the state CPP is to establish a management program and provide a framework for establishing programmatic commitments and goals that will be contained in the Environmental Performance Partnership Agreement (EnPAA) and other plans prepared pursuant to the Clean Water Act. The purpose of the CPP is to document how the state will make its water quality management decisions. (Updated 2010, approved by EPA January 2011)
