Which class corresponds to a facility capacity of more than 7,500,000 gpd with 24 CEUs?

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

Answer: (D)

In Kentucky, the class level for wastewater operator certification is determined by the facility’s design capacity and the required CEUs. A facility with more than 7.5 million gallons per day and needing 24 CEUs falls into the highest class, because both criteria indicate the largest operations and the greatest ongoing training requirement. Therefore, this combination aligns with the top class. The other classes correspond to smaller facilities and generally require fewer CEUs, so they wouldn’t match a plant exceeding 7.5 MGD with 24 CEUs.
