§ 52.048 LIMITATIONS ON CERTAIN DISCHARGES.
   (A)   The following described substances, materials, waters and wastes shall be limited in discharges to municipal systems to concentrations or quantities which will not harm either the sewers, the sludge of any municipal system or the wastewater treatment process or equipment, will not have an adverse effect on the receiving stream or will not otherwise endanger life, limb or public property or constitute a nuisance.
   (B)   The Public Works Director may set limitations lower than the limitations established in the regulations in division (C) below if, in his or her opinion, such more severe limitations are necessary to meet the objectives in division (A) above. In forming his or her opinion as to the acceptability, the Public Works Director will give consideration to such factors as the quantity of subject waste in relation to flows and velocities in the sewers, materials of construction of the sewers, the wastewater treatment process employed, capacity of the wastewater treatment plant and other pertinent factors.
   (C)   The limitations or restrictions on materials or characteristics of wastes or wastewaters discharged to the sanitary sewer, which shall not be violated without approval of the Public Works Director, are as follows:
      (1)   Wastewater having a temperature higher than 150°F or 65°C;
      (2)   Wastewater containing petroleum oil, nonbiodegradable cutting oils or products of mineral oil origin;
      (3)   Wastewater from industrial plants containing floatable oils, fat or grease;
      (4)   Any garbage that has not been properly shredded as defined in § 52.001 of this code. Garbage grinders may be connected to sanitary sewers from homes, hotels, institutions, restaurants, hospitals, catering establishments or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers;
      (5)   Any waters or wastes containing toxic or deleterious substances to such a degree that any such material received in the composite wastewater at the wastewater treatment works exceeds the limits established by the Public Works Director for such materials;
      (6)   Any waters or wastes containing pollutants which result in the presence of toxic or obnoxious gases, vapors or fumes within the POTW in quantities which may cause acute worker health and safety concerns or public nuisance;
      (7)   Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Public Works Director in compliance with applicable state or federal regulations;
      (8)   Quantities of flow or concentrations, or both, which constitute a “slug” as defined in § 52.001 of this code;
      (9)   Waters and wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed, or which are amenable to treatment only to such a degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over the receiving waters;
      (10)   Any waters or wastes which, by interaction with other waters or wastes in the public sewer system, release obnoxious gases, form suspended solids which interfere with the collection system or create a condition deleterious to structures and treatment processes;
      (11)   Pollutants which cause corrosive structural damage to the POTW, but in no case discharges with pH lower than 5.0 unless the POTW is specifically designed to accommodate such discharges; and
      (12)   Any trucked or hauled wastes unless the POTW is designed to adequately treat the wastes and the facility has points designated for such discharges.
