DEQ Recertification

Following initial certification, DEQ requires Installer and Maintenance Provider recertification every three years.

Keep Your DEQ Certification Current

Chemeketa will recertify onsite system installers and maintenance providers who –

  • Complete 18 hours (1.8 Continuing Education Units, CEU’s) of approved continuing education following their most recent certification or within six months after their certification expires
  • Chemeketa will provide recertified persons a serial-numbered, laminated certification card

Notification of Expiration

Prior to initial certification expiration, Chemeketa will notify you (to the address Chemeketa has on file) that your initial certification will be expiring in about a month. This letter will include instructions on how and what to send for recertification, including documentation that you have received 18 hours of continuing education.

  • In most cases, the course completion certificate you receive after you've completed the course works
  • You are responsible for keeping track of your course completion certificates

Approved Classes

The Oregon Environmental Services Advisory Council (OESAC) approve classes listed on their website. If you want to see if a course you have taken will qualify for recertification, view the list of OESAC approved courses.  If you or your organization are holding, or have held, a class that you would like to be evaluated for qualification toward recertification you must submit an application to OESAC.

If you have questions about the requirements of the DEQ class, and your status regarding the course and test requirement, please check out the DEQ website.

Please also refer to the DEQ website for an updated list of certified Installers and Maintenance Providers that includes certification expiration dates.
