Minnesota Pollution Control Agency sets statewide numerical noise limits for stationary sources under Minn. Rules Chapter 7030. Limits vary by Noise Area Classification and time of day, applying uniformly across the state to industrial and commercial noise.
Minn. Stat. section 116.07 authorizes MPCA to adopt noise standards. Minn. Rules 7030.0040 sets daytime and nighttime decibel limits using L10 and L50 metrics across three Noise Area Classifications based on land use. For example, NAC-1 residential limits are 60 dBA (L50) day and 50 dBA (L50) night. The standards apply to stationary sources such as factories, compressors, and HVAC. Local noise ordinances may be more restrictive, but the state floor applies statewide. Aircraft, motor vehicles on public roads, and certain agricultural operations are excluded.
MPCA enforcement may include administrative penalty orders, civil penalties up to $10,000 per day under Minn. Stat. 115.071, and injunctive relief.
