All flow rates, BOD, COD and SS values used in determination of the surcharge of wastewater customers shall be re-evaluated on a periodic basis as determined by the Director and shall be adjusted to reflect any increase or decrease in wastewater treatment costs. However, if there is a major change in the operation to cause changes in value, the values may be increased or decreased based on a study of changes or actual measurements. Every person discharging wastewater to the POTW shall be responsible for notifying the Director of major changes in its operation affecting the quantity or quality of extra strength wastewater discharged. In the absence of the notification, the surcharge applicable to the person shall be based on the data available to the Director at the time the surcharge is billed.
