(a) The System has been designed to handle flows with "normal concentrations" as follows: (i) a five-day, twenty-degree centigrade biochemical oxygen demand of not more than 200 parts per million; (ii) a suspended solids content of not more than 250 parts per million; and (iii) an oil and grease content of not more than 50 parts per million. Flows with concentrations greater than any one or more of those "normal concentrations" would have a deleterious effect and impact on the System including, but not limited to, reducing the hydraulic treatment capacity of the System, increasing treatment and other operating costs, disrupting the normal treatment process, and/or causing discharge limits to be exceeded. Therefore, it is fair, just and equitable to impose a surcharge as follows with respect to flows with concentrations greater than any one or more of those "normal concentrations".
(b) If the Engineer determines, based on the exercise of professional engineering practice, methodology and standards, including measurements, tests and analyses undertaken by the Engineer in accordance with Section 933.05 of this Chapter, that the flow to the System from a property exceeds any one or more of those "normal concentrations", then a surcharge, equal to 100% of the quarterly charge for such property, as measured and determined pursuant to Section 933.07 of this Chapter, shall be added to the quarterly bill for such property prepared pursuant to Section 933.07 of this Chapter.
(c) A surcharge shall continue to be imposed until (i) the entity responsible for such flow advises the Engineer in writing that it has implemented pretreatment facilities and controls on, changed the characteristics of, or otherwise improved, such flow so that such flow no longer exceeds any one or more of those "normal concentrations", (ii) such entity has paid, in advance, to this Village, the costs of the Village in undertaking such measurements, tests and analyses, including the fees and expenses of the Engineer, and (iii) the Engineer determines, based on the exercise of professional engineering practice, methodology and standards, including measurements, tests and analyses undertaken by the Engineer in accordance with Section 933.05 of this Chapter, that such flow no longer exceeds any one or more of those "normal concentrations". However, the aforesaid surcharge shall be reimposed if the Engineer thereafter determines, based on the exercise of professional engineering practice, methodology and standards, including measurements, tests and analyses undertaken by the Engineer in accordance with Section 933.05 of this Chapter, that the flow to the System from such property exceeds any one or more of those "normal concentrations".
