(A) Applications for permits allowing groundwater reclamation discharges will be considered on a case-by-case basis, and each case on a month-by-month basis (see § 52.100), and accepted only after approval by the DEM and/or EPA and a finding that the discharge will not have a detrimental effect on the POTW. If accepted, the discharge shall be pretreated so as to comply with specific pollutant limits as set out in the permit granted for that particular groundwater reclamation discharge.
(B) The following described substances, materials, waters, or waste shall be limited in discharges to municipal systems to concentrations or quantities which will not harm either the sewers, wastewater treatment process, or equipment, will not have an adverse effect on the receiving stream, or will not otherwise endanger life, limb, public property, or constitute a nuisance. The Public Utilities Director may set limitations lower than the limitations established in the regulations below if, in his or her opinion, the more severe limitations are necessary to meet the above objectives. In forming his or her opinion as to the acceptability, the Public Utilities Director will give consideration to the 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 treatability of the waste in the wastewater treatment plant, and other pertinent factors. The limitations or restrictions on materials or characteristics of waste or wastewaters discharged to the sanitary sewer which shall not be violated without approval of the Public Utilities Director are as follows:
(1) Wastewater having a temperature higher than 150°F (65°C);
(2) Wastewater containing more than twenty-five (25) milligrams per liter of petroleum oil, nonbiodegradable cutting oils, or product of mineral oil origin;
(3) Wastewater from industrial plants containing floatable oils, fat, or grease;
(4) Any garbage that has not been properly shredded (for definition of such, see § 52.001). 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 iron, chromium, copper, zinc, and similar objectionable or toxic substances to the degree that any such material received in the composite wastewater at the wastewater treatment works exceeds the limits established by the Public Utilities Director for the materials;
(6) Any waters or wastes containing odor-producing substances exceeding limits which may be established by the Public Utilities Director;
(7) Any radioactive wastes or isotopes of the half-life or concentration as may exceed limits established by the Public Utilities Director in compliance with applicable state or federal regulations;
(8) Quantities of flow, concentrations, or both which constitute a slug as defined herein;
(9) Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed, or are amenable to treatment only to the degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters; and
(10) Any water or wastes which, by interaction with other water 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.
