Frequently Asked Questions About Operator Certification

I am an existing WWTP Operator interested in renewal.

Q: How long is my certification period?

A: From the date of your initial certification (or prior renewal), a WWTP Operator is certified for a period of five years.

Q: I've received a letter that my certification has expired. What does that mean to me?

A: From the date of your expiration you are not a certified operator. To maintain your certification for job/Civil Service requirements, you would need to complete the required renewal contact hours for your grade certification. Upon notice of expiration, you have 1 year to complete the required training. Failure to do so beyond that point will require the applicant to retake the Association of Boards of Certification (ABC) exam, in addition to completing the required training. Only training completed within five (5) years of the date we receive your renewal application will be allowed.

Q: I don't have enough contact hours for renewal; how can I quickly satisfy my renewal requirements before my certificate expires?

Note: We often recommend that operators take a home study correspondence course. This is generally reasonably priced and can be done at the operator's leisure.

Q: Where I work, it's tough to get approval for training. Additionally, there is not much offered in the way of training. How do I satisfy my renewal requirements?

A: Same recommendation as above, and many professional associations conduct local/regional training programs. Select the following link for examples of types of renewal training and a listing of pre-approved training and crediting of hours Renewal Training & Approved Distance Learning

Q: What are the requirements for WWTP Operator Certification in New York State?

A: Please see our web page Requirements for WWTP Operator Certification

In general, certification approval is based on the following:

  • Minimum education requirements.
  • Required training courses.
  • Approved operating experience.
  • Pass the ABC Certification exam.

Q: How do I know what grade level of certification I might be eligible for?

A: The level of certification is based on the facility plant score. This is a worksheet generally on file with the Facility Operations Assistance Section that takes the cumulative point score of all the unit processes that relate to your treatment flow scheme. The plant score indicates what level the chief operator and assistant shift operator must be certified at. The WWTP course training you have completed in conjunction with your education, operating and approved operating experience (at the required plant score) will determine what grade level you may apply for.

Q: What consists of a complete application package?

A: A complete application package contains the following:

  • A copy of your High School or College Diploma, or a High School Equivalency.
  • Completed "Wastewater Treatment Plant Operator Statement of Experience" forms for each WWTP where experience was acquired.
  • A Notice of Training Course Completion for each required training course for the grade certification you seek.
  • A Notice of Training Course Completion for a NYSDEC approved Basic Laboratory Course, or proof that you have satisfactorily completed a NYSDEC laboratory exam (except Grade 1 & 1A candidates).

If your package is deemed complete and adequate by both the NYSDEC Regional Water Engineer (or County Health Department if authorized), and the Facility Operations Assistance Section (FOAS), you will be granted admission to the Association of Boards of Certification (ABC) exam.

Incomplete application packages may be returned and rejected.

Q: What is the "ABC" exam referenced above?

A: The "ABC" exam is a WWTP exam given throughout the country. It is a 3 hour exam that consists of 100 multiple choice questions. A passing score is a grade of seventy (70) or higher. The exam is offered through a testing service, Applied Measurement Professionals (AMP) located throughout New York State and the country. No exam candidates can take a test without NYSDEC approval. To find out more about the new testing procedure go to ABC Exam.

Always remember to make a copy of your entire application for your records in the event it gets lost!
