Overview
Tennessee operators work in systems heavily influenced by Tennessee Valley Authority (TVA) operations and comprehensive watershed management. The Tennessee Department of Environment and Conservation regulates a state with diverse water resources across multiple basins. Understanding TVA operations is important for Tennessee operators.
Applications and renewals are processed through Tennessee's official portal or website. Check with TDEC for current requirements, as regulations update regularly.
Application portal: TDEC Water Programs - This is where you apply, renew, check your license status, and find approved training providers.

License Class Comparison
Tennessee uses a Grade 1-5 System classification system. The class your license needs to match the size and complexity of the facility you're designated responsible operator for.
| Class | Level | System Size | Typical Requirements |
|---|---|---|---|
| Class D/Grade 4 | Entry | Small systems | Limited experience, pass exam |
| Class C/Grade 3 | Intermediate | Small to medium systems | Prior class experience + exam |
| Class B/Grade 2 | Advanced | Medium to large systems | Prior class experience + exam |
| Class A/Grade 1 | Master | Large, complex systems | Extensive experience + exam |
Experience Requirements
Experience requirements in Tennessee 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. Tennessee audits experience documentation during application and renewal.
Pro tip for Tennessee operators: Document the full scope of your experience. Familiarity with specific treatment processes common in Tennessee (groundwater, surface water, reclaimed water, etc.) strengthens your license application and career trajectory.
