(1) No person shall discharge or cause to be discharged any of the following described waters or wastes into any public sewers or wastewater treatment works:
(a) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
(b) Any waters or wastes having a pH lower than 6.0 or higher than 9.0 su, or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the wastewater works
(c) Solid or viscous substances in quantities 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:
• Disposable diapers of any size, nursing pads, baby wipes,
• Cleaning wipes or any other fibrous wipes.
• Cotton balls, pads or swabs.
• Feminine hygiene products
• Unused medication
• Prophylactics
• Facial tissue
• Hair
• Nail polish, polish remover, solvents, paint, turpentine
• Bandages and bandage wrappers
• Syringes, needles and sharps
• Kitty litter
• Dental floss
• Toys
• Wood
(d) Described substances, materials, waters or waste shall be limited in discharge to public sewers or wastewater treatment works to concentrations or quantities that will not harm the sewers, wastewater treatment process or equipment, will not have an adverse effect on the receiving stream or will not otherwise endanger lives, limb, and public property or constitute a nuisance. The Superintendent may set limitations lower than the limitations established in the regulations below if in his opinion more severe limitations are necessary to meet the above objectives. Deliberate dilution with unpolluted water to meet the concentrations established in the regulations below shall not be acceptable. In forming his opinion as to the acceptability, the Superintendent 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, plant capacities and other pertinent factors. The limitations or restrictions on materials or characteristics of waste or wastewater discharged into the sanitary sewers shall not be violated without approval of the Superintendent. Those limitations are as follows:
(i) Any liquid having a temperature higher than 150 degrees Fahrenheit.
(ii) Wastewater containing more than fifty milligrams per liter of petroleum oil, non-biodegradable cutting oils, products of mineral oil origin, floatable oils, fat, wax or grease.
(iii) 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.
(iv) 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, 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 into the public sewer. The following concentrations shall not be exceeded in industrial wastes discharged into the public sewers: total cyanide (CN), 0.5 milligrams per liter (mg/l); hexavalent chromium, 1.0 mg/l, copper, 1.0 mg/l; zinc, 1.0 mg/l; cadmium, 0.2 mg/l; nickel, 2.0 mg/l; phenols, 0.2 mg/l; lead, 0.5 mg/l; mercury, 0.01 mg/l; silver, 0.2 mg/l.
These maximum concentrations may be changed as necessary by the Superintendent or state regulatory agencies based on new information concerning inhibitory substances, to protect treatment plant processes or to ensure plant compliance with state and federal permits or regulations. Industrial discharges 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 is more stringent.
(v) Any waters or wastes containing odor-producing substances exceeding limits that may be established by the Superintendent or any local or state regulatory agencies.
(vi) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits in compliance with applicable state or federal regulations.
(vii) Quantities of flow, concentrations or both which constitute a slug as defined herein.
(vii) Waters or wastes containing substances that are not amenable to treatment or reduction by the wastewater treatment processing employed, are amenable only to such degree that the wastewater treatment plant effluent cannot meet the requirements or other agencies having jurisdiction over discharge to the receiving waters or substances that would result in a violation of the NPDES permit.
(ix) Any water or wastes that by interaction with other water or wastes in the public sewer system, release obnoxious gases, form suspended solids that interfere with the collection system, or create a condition deleterious to structures and treatment processes.
(x) Any wastes with objectionable color not removable by the treatment process.
(xi) 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.
(e) Prohibition of Unpolluted Water. No person shall discharge or cause to be discharged any (unpolluted) surface water, groundwater, roof run-off, storm water, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary sewer. Any existing roof drain connections to sanitary or combined sewers shall be connected into an available storm sewer or shall be disconnected above ground in an appropriate manner approved by the Village. Discharges from roof drains emptying onto the ground surface shall be at least three feet from adjacent property line and shall in no way be directed to flood or otherwise cause damage to adjoining property. The owner of any building situated within the Village is required at his expense to disconnect all existing roof drains from sanitary and combined sewers in accordance with the provisions of this section within 180 days after the date of official notice to do so. Discharge units connecting to a Village sanitary sewer or combination sewer shall be free of all storm water. It is prohibited that any new construction of discharge units shall have any storm water connections of roof drains, footer and foundation tiles or any other connections to a sanitary sewer.
(2) No person shall change the sewer collection system by:
(a) Concealing or tampering with any maintenance fixture, i.e. manhole, cleanout, or similar appurtenances of the sanitary sewer system.
(b) Modifying, repair or replacement of the building sewer service lateral without inspection and/or permission of an authorized representative of the Village of Granville wastewater department.
(c) Modifying the grade surrounding any sanitary manhole or similar device by the property owner or builder without adjusting the public sewer device to grade at the owner's expense.
