Wastewater Operator Licensing Program

Enforcement Branch employees oversee the Wastewater Operator Licensing Program, traveling the state to test and license operators of municipal and industrial wastewater treatment plants.

All wastewater treatment plants must have a licensed operator. Requirements for the licensing of wastewater treatment plant operators were established by Arkansas Pollution Control and Ecology Commission Regulation 3. ADEQ posts training opportunities and maintains a searchable database for licensed wastewater operators in the state.

Wastewater Operator Licenses

Operators qualify for licenses by completing approved training and passing an examination. License types include Class I, II, III, and IV for municipal facilities; Basic and Advanced levels for industrial facilities.

  • Renewal statements are mailed to operators' employers, unless otherwise requested.
  • Licenses expire and renewals are due by June 30 of odd years. There is a 30-day grace period after the expiration date before a late charge goes into effect.
  • To renew licenses, operators must submit all training hours taken toward license renewal on the Training Hours Submittal Form, as well as license fees.
  • A lapsed license may be renewed up to a year after its due date (by June 30 of the next year) if the licensee submits the required training hours and renewal fees by that date. After a year, the license becomes inactive, and the operator must be reviewed/approved by the Arkansas Wastewater Licensing Committee (AWLC) for retesting to reactivate the license.
  • Out-of-state operators moving to Arkansas may apply for a license by reciprocity. Each application for reciprocity will be reviewed by the AWLC for approval.

Multiple Licenses

Any operator can hold multiple licenses (a municipal license and an industrial license). The operator is required to fulfill all of the requirements of both types. Those operators that hold multiple licenses may use the same renewal hours for more than one license but must pay renewal fees for each license held.

Training and Testing

Wastewater operators are required to take training courses, workshops, seminars, or other events from ADEQ-approved sources only. Individuals interested in training must contact the training facilities directly for course information, registration, and any additional training fees.

ADEQ conducts exams and issues and renews licenses for wastewater operators. To register to take an exam, an applicant must submit the license application form and nonrefundable examination fee no less than five business days before the scheduled test date.

ADEQ maintains a list of approved training courses and exam schedules.

License Application Forms and Fees

Licensing applicants should register for classes before applying for a license. ADEQ must receive a completed license application and exam fees 5 business days before the applicant's examination date. Application documents or fees will NOT be accepted at test locations, unless prior arrangements have been made with ADEQ.
