The North Carolina Department of Environmental Quality regulates operations in a state experiencing rapid growth and environmental challenges. Understanding both traditional and advanced treatment is valuable.

| Class A/Grade 1 | Master | Large, complex systems | Extensive experience + exam |
Experience Requirements
Experience requirements in North Carolina are structured as a progression. You must accumulate documented experience at each level before advancing to the next class. Education (engineering, environmental science, etc.) can substitute for some experience, but check specific state rules for your category.
Keep detailed records of your experience: facilities operated, treatment processes, system sizes, dates, and supervisor verification. North Carolina audits experience documentation during application and renewal.
Pro tip for North Carolina operators: Document the full scope of your experience. Familiarity with specific treatment processes common in North Carolina (groundwater, surface water, reclaimed water, etc.) strengthens your license application and career trajectory.
