New Jersey Statutes Title 58. Waters and Water Supply 58 § 11-66

a. Every system shall be operated and maintained by at least one licensed operator. Any person employed in the capacity of a licensed operator not holding the license required for a system may continue in such capacity, at the discretion of the department, if he meets the other requirements of this act and the rules and regulations adopted thereto.

b. The commissioner shall, pursuant to the “Administrative Procedure Act,” P.L. 1968, c. 410 (C. 52:14B-1 et seq.), adopt, and may amend or repeal rules and regulations to classify and reclassify licenses and systems.

c. The department shall upgrade or downgrade the classification of a system whenever the system changes sufficiently to place it in a different classification from the one in which it is classified.

d. If licenses are reclassified by the department, subject to new classification requirements, the licensee at the time of the reclassification shall be reissued, at the time of the next license renewal, the highest license corresponding to the new classification.
