In SC, which credential must be renewed annually for wastewater treatment plant operators?

• A. License
• B. Registration
• C. Certification
• D. Permit

Answer: (C)

Certification is the credential that proves an operator has met the state’s requirements to run a wastewater treatment plant. In South Carolina, this certification must be renewed each year, usually by completing required continuing education hours and paying a renewal fee to keep the credential active. The other options don’t serve as the annual operator credential: a license is a broader professional credential, registration is simply listing a name in a registry, and a permit is an authorization tied to a plant or discharge rather than the operator’s qualifications.
