The Minnesota Pollution Control Agency (MPCA) completed 68 enforcement cases for water quality, air quality, hazardous waste, stormwater, and wastewater violations in the first half of 2025. Environmental enforcement investigations often take several months, in some cases more than a year, to complete the investigation and issue final enforcement documents and fines to regulated parties.
Penalties are calculated using several factors, including harm done or potential for harm to the environment, the economic benefit the company gained by failing to comply with environmental laws, or how responsive and cooperative a regulated party was in correcting problems.
Imposing monetary penalties is only part of the MPCA’s enforcement process. Agency staff continue to provide assistance, support, and information on the steps and tools necessary to bring any company, individual, or local government back into compliance.
