Bottom line: Regulated underground storage tanks (USTs) in New Jersey need designated trained Class A, Class B, and Class C operators. Class A and B are the “program” roles. Class C is on-site first response. One person can hold more than one class if trained for each.
Why this exists
Federal EPA rules (40 C.F.R. Part 280) and New Jersey’s UST rules (N.J.A.C. 7:14B) require operator training so tanks are run by people who understand release detection, spill/overfill prevention, corrosion protection, emergencies, and recordkeeping.
Class A — big-picture operator
Primary responsibility to operate and maintain the UST system. Resources, people, overall program, training, records, emergency readiness.
Class B — day-to-day program operator
Implements field-side compliance: release detection, prevention equipment, records, performance standards. Many facilities designate the same trained person as both A and B.
Class C — first response on site
Often clerks. Respond to alarms and spills, notify A/B and emergency responders. Must be trained before taking the role.
How you become Class A/B in New Jersey
Complete the required New Jersey Class A/B training and pass the ICC exam. Some out-of-state credentials may qualify for reciprocity. Retraining can be required if DEP finds significant non-compliance.
Where names go on paper
Class A and Class B operators are identified on the New Jersey Underground Storage Tank Facility Certification Questionnaire.
Can a company be your A/B?
Yes. You can designate a contractor. You still own the tanks and keep legal responsibility. That is exactly what UST NJ is built to do.
