Why you need to get certified: Effective July 1, 2019, significant changes to the wastewater certification program regarding certificate expiration were made by the Illinois Pollution Control Board. Pursuant to 35 Ill. Adm. Code 380.700 (c), all Class K and Class R Certificates of Technical Competency issued 2019 or earlier shall expire on July 1, 2024.

Class K and R certificates are non-renewable. Operators must retake the examination and reapply when a Class K or Class R certificate expires. 

Class K and Class R operators who intend to take the test must submit an Examination Request for Industrial Wastewater Operator Recertification. This IEPA form:
