(A) All industrial users of the POTW are subject to industrial waste surcharges on discharges which exceed the levels stated in § 51.012.
(B) The amount of surcharge will be based upon the mass emission rate (in pounds per day) discharged above the levels listed in § 51.012. The amount charged per pound of excess will be set forth in the Schedule of Charges And Fees.
(1) The volume of flow used in determining the total discharge of wastewater for payment of user charges and surcharges shall be based on the following:
(a) Metered water consumption as shown in the records of meter readings maintained by the city; or
(b) If required by the city or at the individual dischargers option, other flow monitoring devices which measure the actual volume of wastewater discharged to the sewer. Such devices shall be accessible and safely located, and the measuring system shall be installed in accordance with plans approved by the city. The metering system shall be installed and maintained at the users expense according to arrangements that may be made with the city.
(c) Where any user procures all or part of his water supply from sources other than the city, the user shall install and maintain at his own expense a flow measuring device of a type approved by the city.
(2) The character and concentration of the constituents of the wastewater used in determining surcharges shall be determined by samples collected and analyzed by the city. Samples shall be collected in such a manner as to be representative of the actual discharge and shall be analyzed using procedures set forth in 40 CFR Part 136.
(3) When the quantity of wastewater discharged at any point exceeds 5% of total daily wastewater flow as measured at the treatment plant, the user discharging such wastewater shall install and maintain, at his own expense, a wastewater flow meter and recorder of a type approved by the Director for the purpose of determining the volume of flow to be charged. Each separate industrial plant will be considered and assessed individually even though a User may operate two or more industrial plants on the city of Goldsboro's sewerage system.
