(a) Where oil and grease are a byproduct of food preparation and/or cleanup, reasonable efforts shall be made to separate waste oil and grease into a separate container for proper disposal. Except as contained in byproducts of food preparation and/or cleanup, waste oil and grease shall not be discharged to any drains or grease interceptors. Such waste shall be placed in a container designed to hold such waste and either utilized by industry or disposed of at suitable locations.
(b) None of the following agents shall be placed directly into a grease interceptor, or into any drain that leads to the interceptor:
(1) Emulsifiers, de-emulsifiers, surface active agents, enzymes, degreasers, or any type of product that will liquefy grease interceptor wastes.
(2) Any substance that may cause excessive foaming in the sanitary sewer system, or
(3) Any substance capable of passing the solid or semi-solid contents of the grease interceptor to the sanitary sewer system.
(c) The influent to interceptors shall not exceed 150 degrees Fahrenheit (150 F). The temperature at the flow-control-device inspection port shall be considered equivalent to the temperature of the influent.
(d) Toilets, urinals, and other similar fixtures shall not discharge through a grease interceptor.
(e) Waste shall only enter the grease interceptor through the inlet-flow-control device.
(f) Where food-waste grinders are installed, the waste from such units shall discharge directly into the building drainage system without passing through a grease interceptor. Living quarters, as defined in Section 724.03(a)(5), are exempted from this requirement. (Ord. 27-2007. Passed 3-26-07.)
