Information for Tank System Inspectors

​Tank System Inspector Credential

In order to inspect a tank system that is regulated under Wisconsin Administrative Code ATCP 93 for the purpose of administering and enforcing ATCP 93, you must hold a tank system inspector certification issued by DATCP and be an authorized agent of the department. 

To initially obtain Tank System Inspector certification, you must take the DATCP tank system inspector training class and pass the required exam. There are no fees to apply for or renew a Tank System Inspector credential. See the fact sheet below for additional information:
