D. 
Construction materials, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, wood, paunch manure, coffee grounds, fur, wax, cement, hops, spent grain, whole blood, fetus, products of an abortion, surgical specimens, hair fleshing, entrails, paper dishes, cups and milk containers, either whole or ground by garbage grinders, filter media or any solids or viscous substances capable of causing obstruction to the flow in sewers or other interferences with the proper operation of the sewer system.
E. 
Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either single or by interaction with other wastes, to injure or interfere with any sewage treatment process, or to constitute a hazard to humans or animals, or to create a public nuisance, or to create any hazards in the receiving waters of a sewage treatment plant effluent.
F. 
Any waters or wastes which are not in compliance with federal standards promulgated pursuant to the Federal Water Pollution Control Act Amendments of 1972 (FWPCAA), and/or any other federal and/or state standard for water pollution control which is more stringent.
G. 
Any waters or wastes as defined in 40 CFR 128.131 of the Code of Federal Regulations and as amended.
No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes or any wastes listed within the rules of the Sewer District found to harm the trunk sewer, interceptor sewers, system structures, a Sewer District sewer or public sewer tributary thereto, the sewage treatment process or the equipment, have an adverse effect on the receiving stream or endanger life, limb, public property, or constitute a nuisance. The criteria used in forming the rules of the Sewer District include such factors as the quantities of said wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, the capacity of the sewage treatment facilities and the likelihood of harm, injury or nuisance. The characteristics of the effluent subject to review will be determined from the sampled wastewater collected at a control manhole prior to entering the public sewers. The substances, materials or wastes prohibited in the first instance, but subject to review by the Town are:
A. 
Any liquid or vapor having a temperature higher than 150° F. (65° C.).
B. 
Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of 100 milligrams per liter, or containing substances which may solidify or become viscous at temperatures between 32° and 150° F. (0° and 65° C.).
C. 
Any garbage that has not been properly shredded or triturated. The installation and operation of garbage grinders equipped with a motor greater than 3/4 horsepower (0.76 hp metric) shall be only by permit issued by the Superintendent.
D. 
Any water or wastes containing strong acid, metal pickling wastes, or concentrated plating solutions, whether neutralized or not.
E. 
Any waters or wastes containing iron, chromium, copper, zinc and similar objectionable or toxic substances.
F. 
Any water or wastes containing phenols or other taste- or odor-producing substances, in such concentrations exceeding limits which shall be established by the Superintendent as necessary, after treatment of the composite sewage, to meet the requirements of the state, federal or other public agencies having jurisdiction of such discharge to the receiving waters.
G. 
Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations.
H. 
Materials which contain or cause:
(1) 
Unusual concentrations of inert suspended solids, such as, but not limited to: Fuller's earth, lime slurries, and lime residues, or of dissolved solids, such as, but not limited to, sodium chloride and sodium sulphate.
(2) 
Excessive discoloration at the treatment plant or in the receiving waters, or in the sewage system, such as, but not limited to, dye wastes and vegetable tanning solutions.
(3) 
Unusual biochemical oxygen demand (BOD), chemical oxygen demand (COD), or chlorine requirements in such quantities as to constitute a significant additional load on the sewage treatment works, except as provided for under Article IX.
(4) 
Unusual volume of flow or concentration of wastes constituting "slugs," as defined herein.
I. 
Waters or wastes containing substances which are not amenable to treatment or reduction in concentration by the sewage treatment plant process employed, or are amenable to treatment only to such a degree that the sewage treatment plant effluent cannot meet the requirements of regulatory agencies having jurisdiction over discharge into the receiving waters.
The Superintendent and Town Engineer, after a hearing, shall either prevent the discharge of unacceptable water and wastes or issue a license or permit which is properly conditioned upon findings and the standards of safety prescribed by this chapter or the rules of the Sewer District. The rules of the Sewer District shall include surcharges, pretreatment requirements and any measure or combination of measures which are necessary to preserve the sewer system, its structures and equipment, and the health, safety and well-being of the employees, the community and the biota of the receiving waters.
Any discharge which, in the belief of the Superintendent, will cause serious, imminent harm, injury or adverse effect on the sewer system structures or equipment, or to any persons or to the biota of the receiving water, the Superintendent shall take any temporary action necessary to protect the public health, safety or welfare without a prior hearing or order of the Town Board. Review of any emergency action by a hearing will be accomplished without delay to determine what, if any, permanent restriction is necessary. The Superintendent acting upon belief that an emergency exists shall be indemnified against any personal liability that may arise in the performance of his or her duties to protect the public health, safety or welfare of the Town.
Waters bearing toxic substances above the standard set for normal sewage or pathogenic bacteria shall not be discharged into the public sewers, and their discharge is prohibited unless the rules of the Sewer District or, upon a finding by the Town Board, it determines that such concentration will not adversely affect any of the biochemical, chemical or other sewage treatment process or sewage system. The following is a partial list of toxic substances and pathogenic bacteria:
A. 
Antibiotics.
B. 
Elemental bromine, iodine, chlorine, fluorine.
C. 
Creosols or creosotes.
D. 
Phenol and phenolic compounds that convert to phenol in the sewage system.
E. 
Sulfonamides, toxic dyes (organic or mineral).
F. 
Berylium and berylium compounds.
G. 
Mercury and mercury compounds.
H. 
All strong oxidizing agents such as chromates, dichromates, permanganates, peroxides, etc.
I. 
Any strong reducing agents causing hazardous conditions in the sewage system.
J. 
Chemical compounds producing toxic, flammable or explosive gases, either upon acidification, alkalinization, oxidation, or reduction.
K. 
Wastes from industrial processes or hospital procedures containing viable pathogenic organisms.
The concentration in sewage of any of the following toxic substances shall not exceed the concentration limits specified below when discharged into the public sewers. The Sewer District may revise with its rules these limits or insert additional items after a hearing when, in the opinion of the Superintendent, the Department of Health or the Town Board, the need for a rule change is indicated. The following list contains the permitted toxic substances and levels of concentration:

NOTE:
Federal limits for any of the above toxic substances, if more stringent, shall govern.
When the findings of the Superintendent, Town Engineer, and/or Town Board show that the volume of a single toxic industrial waste discharge or combined toxic industrial waste discharge of a group of industries within a single contributory area is so large as to raise a question of the ultimate concentration of toxic substances entering a treatment plant, or in cases where it is known that the toxic substances in concentrations involved will be removed by treatment works without causing deleterious effects of any kind to the treatment process or the receiving waters, the Superintendent, Town Engineer, and/or Town Board may rule that separate or special concentration limits shall be used by the contributors in that area.
Any discharge which, in the belief of the Superintendent, will cause serious, imminent harm, injury or adverse effect on the sewer system structures or equipment or to any persons or to the biota of the receiving waters, the Superintendent shall take any temporary action necessary to protect the public health, safety or welfare without a prior hearing or order of the Town Board. Review of any emergency action by a hearing will be accomplished without delay to determine what, if any, permanent restriction is necessary. The Superintendent, acting upon the belief that an emergency exists, shall be indemnified against any personal liability that may arise in the performance of his duties to protect the public health, safety or welfare of the Town.
