Commercial Animal Waste Technician Licensing


Minnesota law requires Commercial Animal Waste Technicians (CAWT) to obtain a state license. If you apply or manage manure on a for-hire basis, you must be licensed. There are two categories, solid and liquid. An open-book exam is required as part of the license application.
