Onsite Wastewater Treatment Professionals: Continuing Education

An onsite professional holding a valid certificate by examination may apply for a certificate renewal by demonstrating successful completion of professional development hours (PDH), in lieu of re-taking the certification exam. When a certificate is issued in the first (even numbered) year of the two-year certificate period, the certified professional must successfully complete a minimum of 12 PDH of continuing education during the certificate period. For certificates issued in the second (odd numbered) year of the two-year certificate period, there are no PDH requirements until the next 2-year cycle. PDH completed within 30 days prior to obtaining initial certification by examination will be accepted for the purposes of complying with the PDH requirement for certificate renewal.

All PDH courses or programs must be approved by the Department to be used toward certificate renewal. To find a current listing of pre-approved educational programs, see the link below:
