A wastewater operator with a facility capacity of less than 50,000 gpd and 12 continuing education units (CEUs) belongs to which class?

• A. Class 3
• B. Class 1
• C. Class 4
• D. Class 2

Answer: (B)

In Kentucky, the license class you hold is tied to both the maximum daily capacity of the plants you operate and the continuing education units (CEUs) you’ve earned. A facility with capacity under 50,000 gallons per day and 12 CEUs matches the entry-level Class I license, which is designated for smaller wastewater systems and has a 12 CEU requirement to maintain. This is the best fit because it aligns exactly with the given size and CEU total. If the facility were larger or the CEU requirements were different, you’d move to a higher class that corresponds to greater capacity and typically more CEUs or additional exams.
