Conn. Agencies Regs. § 22a-416-3
There shall be four classes of wastewater treatment facilities: Class I, Class II, Class III, and Class IV.
The commissioner classifies each wastewater treatment facility in Connecticut by calculating points therefore in accordance with appendix A and applying the following chart:
Facility Class | I | II | III | IV |
Points | 30 or less | 31-55 | 56-75 | 76 or more |
The commissioner maintains a list of wastewater treatment facilities in Connecticut which identifies the class of each such facility.
The commissioner shall notify the owner of a wastewater treatment facility in writing if the commissioner determines under subsection (b) of this section that the class of such facility should be revised as a result of equipment or treatment process modifications thereat. Within 30 days of receiving such notice, the owner may request in writing a consultation with the commissioner concerning the proposed change of class. Within 45 days of such consultation the commissioner will provide the owner with a written decision as to whether he or she will retain the existing facility class or revise it in accordance with the commissioner's prior notice.
