The Minnesota Pollution Control Agency (MPCA) collects data on businesses that generate or transport hazardous waste.
Hazardous waste licenses. Use a generator's hazardous waste identification number (HWID) to generate a copy of the Hazardous Waste Generator License issued by MPCA. This search will only display licenses for generators in Greater Minnesota; it does not include licensees in the seven-county Metro Area.
