(b) A wastewater treatment plant may be classified other than as indicated in subdivision (a) if:
(1) the wastewater treatment plant uses unconventional or innovative approaches due to conditions of flow or unusual requirements for discharge to a receiving water;
(2) the conditions of flow or the use of the receiving waters require an unusually high degree of wastewater treatment plant operational control; or
(3) the wastewater treatment plant uses an approved method of wastewater treatment not included in subdivision (a).
(c) Satellite plants shall not be classified separately. A satellite plant and the main wastewater treatment plant shall be classified as a single wastewater treatment plant.
(d) Within 45 days of receiving written notice of any change in reportable items in section 3676(b) or (c), the Office of Operator Certification shall either reclassify the wastewater treatment plant or make a determination that the change does not result in a need for reclassification.
