Wastewater Operator Certification

In January 2006, the Maine DEP transferred all of the administrative duties for Maine's Wastewater Operator Certification program to NEIWPCC, administered through the NEIWPCC South Portland/JETCC office. These duties include coordinating certificate renewal, record keeping, and applications for Maine's Wastewater Treatment Plant Operator exams offered each May and November. Eligibility of training courses for continuing education credit must be approved by Maine DEP. To receive training approval, proof of training and participation in training courses should be submitted directly to the NEIWPCC South Portland/JETCC office.


Wastewater Operator Exam

Wastewater operators in Maine will soon have a new way to take the exam needed to receive certification. Beginning in March 2015, certification testing will change from pencil and paper to a computerized test. Computer based testing will modernize Maine Department of Environmental Protection’s Wastewater Operator Certification process and testing.

Computer-Based Testing (CBT) will give examinees a more convenient testing schedule, more opportunities to take the exam, and receive results immediately upon completion of the exam.

CBT will be available beginning March 16, 2015. Applied Measurement Professionals (AMP) provides testing services for the exam. Exams can be scheduled at any AMP Assessment Center in the United States. There are currently two AMP Assessement Centers in Maine - Portland and Holden, as well as a location in Portsmouth, NH. Testing times are available Monday through Friday, 9:00 AM or 1:30 PM with slots at least one Saturday per month.

CBT Exam applications will be accepted in the NEIWPCC South Portland/JETCC office beginning January 12, 2015. The CBT application fee is $75 payable to NEIWPCC/JETCC. This fee allows an examinee to take the same grade level exam as many times as needed within a two-year approval period. Unless applying for a different grade level or the two-year period has expired, it is not necessary to reapply to NEIWPCC/JETCC or pay another application fee. There is a separate $96 exam fee payable to AMP for each attempt.

Paper testing will still be available for everyone on Wednesday, May 13, 2015 in the three historic testing locations: Portland, Bangor, and Presque Isle. After the May 2015 exam, paper testing will only be offered in Presque Isle. The application for a paper exam and fee of $125 payable to NEIWPCC/JETCC are due in the NEIWPCC South Portland/JETCC office by Friday, March 27, 2015. They should be postmarked by Monday, March 23, 2015.

For Presque Isle only, the Fall 2015 paper exam is scheduled for Wednesday, November 18, 2015.
