If the Chief operator goes on vacation, what level of certification does the fill-in operator need to have?
A. Any operator acting as the Chief operator, even if it is only temporary, is required to hold a certificate at the same level as, or greater than, the treatment facility or distribution system being operated. For example, if the treatment plant is classified as a T4, the Chief operator, or operator acting as the Chief operator, must hold either a T4 or T5 certificate.
