Minnesota law requires companies, site managers and applicators that manage or apply manure for hire to obtain a Commercial Animal Waste Technician (CAWT) license from the Minnesota Department of Agriculture (MDA).
MDA issues three types of CAWT licenses
CAWT Site Manager
A Commercial Animal Waste Technician Site Manager Training Manual is available as a PDF to print here and at the UME website. (New 2015 Manual coming soon, for current version contact MDA)
Site Managers must pass the certification exam (80% or better) for a license to be awarded. Each test contains 100 multiple-choice questions pulled directly from the study manual. The test is monitored.
