No person shall discharge or cause to be discharged to the wastewater treatment system any of the following described substances, materials, waters, or wastes:
(A) Any liquid or vapor having a temperature higher than 150° F. (65° C.).
(B) Any water or wastes containing floating oils, fat, or grease or containing more than 50 milligrams per liter of petroleum oil, nonbiodegradable cutting oils, or products of mineral oil origin.
(C) Any water or wastes containing dissolved gases (such as H2S, sulfur oxides, nitrogen oxides, and ammonia) in concentrations sufficient to cause poisonous or toxic fumes or wastewater, or a malodorous gas of harmful condition.
(D) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, asphaltic materials, cement or concrete, paunch manure, hair and fleshings, entrails, lime slurry, lime residues, beer or distillery spent grains, chemical residues, paint residues, cannery waste bulk solids, or any other solid or viscous substances, in amounts capable of causing obstruction to flow in, or interference with the proper operation of a wastewater treatment system.
(E) Any water or wastes that contain phenols in excess of 0.50 mg/l. These limits may be modified if the aggregate of contributions throughout the area of service create treatment difficulties, or produce wastewater treatment plant effluent discharges to receiving waters which may be prohibitive.
(F) Any water or wastes, acid or alkaline in reaction, and having corrosive properties capable of causing damage or hazard to structures, equipment or personnel of the Water and Sewer Commission. The acidic or alkaline character of such wastes must be neutralized at all times to within the permissible range of pH, which range is between 6.0 and 9.0.
(G) Any water or wastes containing objectionable or toxic substances to such degree that any such material received in the composite wastewater at a wastewater treatment plant exceeds the limits established by the Sanitation District No. 1 for such materials.
