Minnesota Administrative Rules Agency 167 - Pollution Control Agency
📘 Minnesota Administrative Rules (MAR) — Agency 167: Pollution Control Agency
Agency 167 — Minnesota Pollution Control Agency (MPCA) administers environmental regulations under Minnesota Administrative Rules (MAR). These rules are designed to:
Protect air, water, and land resources
Regulate pollution from industrial, agricultural, and municipal sources
Establish permitting procedures for emissions, waste disposal, and water discharges
Provide procedures for enforcement, penalties, and appeals
MPCA’s authority comes from state environmental statutes, including the Minnesota Environmental Policy Act, the Minnesota Clean Water Act, and other state laws. The rules implement these statutes and define compliance obligations for individuals, businesses, and local governments.
⚖️ Key Principles of MAR Agency 167
Permitting: MPCA rules require permits for emissions, wastewater discharges, and waste management.
Standards and Limits: MAR sets numerical and qualitative standards for pollutants, air quality, water quality, and hazardous substances.
Inspections and Reporting: Regulated entities must report discharges, emissions, or spills and allow MPCA inspections.
Enforcement: MPCA can issue fines, compliance orders, or license suspensions.
Judicial Review: Regulated parties may appeal agency decisions to administrative law judges or courts.
📂 Judicial Review and Case Law
