Wastewater treatment plants (WWTPs) serve an essential function to protect public health and the environment, including Washington's rivers, lakes, streams, and Puget Sound. The certification of wastewater treatment plant operators helps make sure they are knowledgeable, and that WWTPs are properly operated and maintained.

Wastewater Treatment Plant Operator Certification Program Guidance
We adopted changes to chapter 173-230 WAC Certification of Operators of Wastewater Treatment Plants in 2019. This:
- Established a fee schedule in rule as directed by the Legislature in 2018.
- Included multiple changes, such as:
- Providing for an Operator in Training and respective education and experience qualifications for Groups II-IV.
- Acknowledging new technologies in wastewater treatment.
- Creating stand-alone sections where more information and clarity were needed.
- Clarifying rule language to codify existing program practice.
