(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 clean up, 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 1044.02(a)(2) above, are exempted from this requirement.
