(a) The following terms as used in this section shall have the meanings ascribed to them as shown:
(1) “Normal sewage” means sewage which when analyzed shows by weight a daily average of not more than 250 parts per million of suspended solids, and not more than 200 parts per million of biochemical oxygen demand (BOD).
(2) “Suspended solids” means solids that either float on the surface of, or are in suspension in water, sewage, or other liquids and which are removable by laboratory filtering.
(3) “BOD” (denoting biochemical oxygen demand) means the quantity of oxygen utilized in the biochemical oxidation of organic matter, under standard laboratory procedure, in five (5) days at twenty (20) degrees centigrade, expressed in parts per million by weight.
(b) Sewage or industrial wastes above normal sewage strength, but acceptable for discharge into the sanitary sewerage system shall be subject to a surcharge. The surcharge shall be determined on the basis of either or both of two constituents of the water or wastes:
(1) Total suspended solids, and/or
(2) Five day BOD at twenty (20) degrees centigrade and as herein provided.
(c) When either or both the total suspended solids and the BOD of a water or waste accepted for admission to the system exceed the values of their constituents for normal sewage, the excess concentration in either or both, as the case may be, shall be subject to a surcharge as follows:
(1) Pounds of excess suspended solids per day x $0.23/lb. = suspended solids surcharge.
(2) Pounds of excess BOD per day x $0.28/lb. = BOD surcharge.
(d) In addition to the surcharge, the user will pay the user charges as defined in Section 929.02.
(e) The pounds of BOD per day and/or pounds of suspended solids per day, above the concentrations previously described for normal strength sewage that are discharged to the sewerage system, shall be determined by the Village of Plain City or its authorized representative.
(f) In addition to a surcharge on BOD and suspended solids, the Village shall have the right to surcharge any user for the discharge of any other pollutant into the sewage system or for any other reason that it deems necessary and appropriate, such as excessively high rates of discharge.
