(a) Classes established. The director shall classify commercial and industrial establishments that routinely discharge BOD and total suspended solids concentrations exceeding 250 mg/L into the following class groups:
CLASS | DESCRIPTION
|
(1) | EATING PLACES: Includes restaurants and other establishments that engage in preparation of food and beverage served directly to the consumer. |
(2) | EQUIPMENT SERVICE FACILITIES: Includes establishments that perform washing, cleaning, or servicing of automobiles, trucks, buses, machinery, or equipment and includes public facilities, facilities limited to specific companies, and attended and coin-operated establishments. |
(3) | FOOD AND KINDRED PRODUCTS PROCESSING: Includes commercial establishments that engage in the preparation, packaging, processing, or distribution of food, food products, grains, or produce, other than those included in Class (1) and that discharge less than 200,000 gallons of wastewater per month. |
(4) | DRINKING PLACES: Includes bars, lounges, clubs, and other establishments that do not engage in any food preparation but that engage in the sale of beer, wine, liquor, or any other beverage served directly to the consumer. |
(b) Assessment of surcharge class rate. The director shall assess an industrial surcharge rate for each class group based on industrial waste strength determinations established by averaging grab or composite samples, or both, taken from a representative number of establishments in each group and shall apply this rate to the water consumption or metered wastewater of the establishment. If the establishment is within a larger facility for which water usage is determined from a master meter, the director shall determine an estimated volume for the establishment to which the surcharge rate is applied. The director shall then add the appropriate industrial surcharge to billings for regular water and wastewater service for each establishment classified into a class group.
(c) Exceptions to surcharge class rate. If an establishment contains operations from more than one of the class groups, and the director determines that the surcharge rate for a particular class group would not adequately compensate the city for its cost of treatment, the director may:
(1) assess a surcharge rate based on a proportional average of the class group rates involved; or
(2) require the establishment to be billed for an industrial surcharge computed under the requirements of Section 49-18.12(1)(A) or (B), whichever applies.
(d) Election of standard surcharges. The owner or agent of the owner of an establishment classified into a class group may elect to have the industrial surcharge billed directly under Section 49-18.12(1)(A) or (B), whichever applies, rather than under this section by making application to the director and paying the required sampling costs.
(e) Authority to revise rates. The director may, from time to time, revise class group surcharge rates based on analysis of current samples. (Ord. Nos. 19201; 21061; 21430; 26925; 28084)
