(a) No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers or treatment works:
(1) Any gasoline, benzine, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
(2) Any waters or wastes having a pH lower than 6.0 or having any other corrosive property capable or causing damage or hazard to structures, equipment and personnel of the wastewater works.
(3) Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers or other interferences with the proper operation of the wastewater facilities, such as, but not limited to, ashes, bones, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
(b) The following described substances, materials, waters and wastes shall be limited in discharge to Municipal systems to concentrations or quantities which will not harm either the sewers, wastewater treatment processes or equipment; will not have an adverse effect on the receiving stream; will not otherwise endanger life, limb or public property; and will not constitute a nuisance. The Village Administrator may set limitations lower than the limitations established in the following regulations if, in his or her opinion, such more severe limitations are necessary to meet the above objectives. Deliberate dilution with unpolluted water to meet the concentrations established in the following regulations shall not be acceptable. In forming his or her opinion as to the acceptability, the Village Administrator will give consideration to such facts as the quantity of subject waste in relation to flows and velocities in the sewers, materials of construction of the wastewater treatment plant, degree of treatability of the waste in the wastewater treatment plant, and other pertinent factors. The limitations or restrictions on materials or characteristics of waste or wastewater discharged to the sanitary sewers which shall not be violated without approval of the Village Administrator are as follows:
(1) Wastewater having a temperature higher than 150 degrees Fahrenheit.
(2) Wastewater containing more than fifty milligrams per liter of petroleum oil, nonbiodegradable cutting oils, products of mineral oil origin, or floatable oils, fat, wax or grease.
(3) Any garbage that has not been properly shredded. 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.
(4) Any waters or wastes containing solids, liquids or gasses in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, or harm the waters of the wastewater treatment plant, including, but not limited to, cyanides, hexavalent chromium, copper, zinc, cadmium, nickel and phenols in the waste as discharged to the public sewer. The following concentrations shall not be exceeded in industrial wastes discharged to the public sewers:
A. Total cyanide (CN): 0.5 mg/l;
B. Hexavalent chromium: 1.0 mg/l;
C. Copper: 1.0 mg/l;
D. Zinc: 1.0 mg/l;
E. Cadmium: 0.2 mg/l;
F. Nickel: 2.0 mg/l;
G. Phenols: 0.2 mg/l;
H. Lead: 0.5 mg/l;
I. Mercury: 0.01 mg/l;
J. Silver: 0.2 mg/l.
These maximum concentrations may be changed as necessary by the Village Administrator or State regulatory agencies based on new information concerning inhibitory substances or to protect treatment plant processes. Industrial dischargers covered by Federal pretreatment requirements shall meet those limitations specified under the effluent guidelines published under Section 304(b) and 307(b) of the Federal Act or the above concentrations, whichever are more stringent.
(5) Any waters or wastes containing odor-producing substances exceeding limits which may be established by the Village Administrator or any local or State regulatory agencies.
(6) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits in compliance with applicable State or Federal regulations.
(7) Quantities of flow, concentrations, or both, which constitute a "slug" as defined herein.
(8) Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processing employed, or are amenable only to such a degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters; or substances that would result in a violation of the NPDES permit.
(9) 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.
(10) Any wastes with objectionable color not removable by the treatment process.
(c) All testing to identify any of the above mentioned pollutants, waters or wastes shall be in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater.
