Which class corresponds to a facility capacity of 2,000,000 to 7,500,000 gpd with 24 CEUs?

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

Answer: (C)

Matching certification class to the plant’s design flow is what this item tests. In Kentucky, each class corresponds to a specific range of facility capacity (gallons per day) and a set number of continuing education units (CEUs) required for renewal. A facility handling between 2,000,000 and 7,500,000 gpd falls into Class 3, and operators must complete 24 CEUs for renewal. So this class best fits the given capacity and CEU requirement. The smaller-capacity classes use lower CEU counts and smaller flow ranges, while larger facilities go with higher classes and typically higher CEU needs, which is why the 2–7.5 MGD range with 24 CEUs maps to Class 3.
