Tennessee requires that the person in direct charge of a treatment plant, distribution system or collection system holds an operator certificate at a grade equal to or higher than the grade of the facility. For a small system, that single rule is often the hardest thing about staying compliant — because when your certified operator retires, resigns or is off sick, the requirement does not pause.
How Tennessee certification works
Operators are certified Grade I through Grade IV, with Grade IV the highest, plus a separate Small Water System classification. Certification is by examination, with a minimum passing score of 70%, and it is maintained through continuing education — 6 contact hours per renewal period for Grade I and II, 12 hours for Grade III and IV.
The grade requirement follows the facility, not the person’s convenience. A Grade III plant needs someone Grade III or above in direct charge. You cannot staff down to what you can hire.
Our certifications
- Grade IV — Wastewater Treatment. The highest state wastewater operator certification.
- Grade III — Water Treatment.
- Grade II — Distribution.
Why systems contract operations
Rarely because they want to outsource. Usually because of one of these:
- The certified operator left. A replacement at the right grade is not quickly found in a rural market, and the system is non-compliant from the day they go.
- The plant is too small to justify a full-time role but too regulated to run without one.
- Compliance has slipped and the system needs someone who can both operate and correspond with DEC/EPA credibly.
- Coverage gaps. Holidays, illness and turnover leave stretches with nobody qualified in direct charge.
What contract operations covers
Scope is set per system, but typically includes day-to-day process control and operational decisions, sampling and coordination with certified laboratories, regulatory reporting including NetDMR submissions, maintaining operational records to the standard an inspector expects, routine maintenance oversight and flagging capital needs early, and acting as the point of contact for regulatory correspondence.
Where a system is already in trouble, that extends to notice of violation and Director’s Order response.
Operator-led, not consultant-led
S&L Environmental is run by a licensed operator with direct operating experience at the City of Memphis T.E. Maxson Wastewater Treatment Plant, and Public Works Director responsibilities for the Town of Mason, Tennessee. Every procedure we write is one we would have to follow ourselves at 3am.
That is a genuine difference from firms that produce compliance documentation without anyone on staff who operates a plant. Both can write you an SOP. Only one has found out what happens when the SOP is wrong.
Service area
West Tennessee, Northern Mississippi, and Eastern Arkansas.
Municipal systems, utility districts and industrial facilities. If you have lost your certified operator or are about to, that is a conversation worth having before the gap opens rather than after.
