Interested in becoming a water or wastewater operator but don’t have enough time or experience? If you pass an approved exam (Ohio EPA or third party) prior to obtaining the required operating experience, you will be considered Operator-in-Training* (OIT).

If you pass an Ohio EPA examination, when you obtain the required operating experience you will need to fill out the OIT documentation form (PDF or Word).

If you pass a third-party examination, you will need to submit an application for certification through the eBusiness Center when you have completed the required operating experience. There is a $45 fee for the third-party certification application and the required operating experience must be documented.

* This excludes class III and IV examinations.
