Current through Register Vol. 39, No. 6, September 16, 2024

(a) Water pollution control collection systems operated to convey wastewater to water pollution control systems which are permitted or tributary to municipalities, regional water pollution control systems, water and sewer authorities, public utilities, or are a Grade II, III or IV state or federally owned system, are subject to classification in accordance with Rule .0303(b) of this Section. Any collection system, regardless of ownership, is classified pursuant to this Rule and required to designate an Operator in Responsible Charge (ORC) and a Back-up Operator in Responsible Charge (Back-up ORC) if the Commission determines that the system is not being operated and maintained in a manner which prevents the escape of wastewater from the system into the environment.

(b) Collection systems are assigned the lower grade classification that is either:

(1) the same as the grade of the biological water pollution control system to which the collection system is tributary; or

(2) based on the population served by the collection system in accordance with the following chart:
(A) 1,500 or less Grade I;

(B) 1,501 to 15,000 Grade II;

(C) 15,001 to 50,000 Grade III;

(D) 50,001 or more Grade IV.

In the event that the population served cannot be determined, the equivalent population served shall be calculated by using the design flow of the system divided by a flow of 60 gallons per day per person.
