(A) All non-domestic users shall be required to install and maintain a grease, oil and sand interceptor when the General Manager and/or District Engineer, or his, her or their designee, finds that it is necessary for the proper handling of:
(1) Liquid waste containing grease;
(2) Flammable wastes; and
(3) Sand.
(B) Any other harmful constituents that may be properly eliminated from the sewerage system by use of an interceptor or trap. An interceptor is not required for a building used solely for residential purposes so long as there is no common food preparation facility. An interceptor shall be required when the wastewater flow from the building is anticipated to contain grease, flammable substances, sand or other harmful ingredients in amounts or concentrations which would be in violation of a pretreatment standard or, in the discretion of the District, present the possibility of causing or contributing to the fouling of or the blockage of or other damage to the District sewerage system.
