No person shall discharge or provide a connection for discharging or draining into any public sanitary sewer or tributary sewer thereto any stormwater, surface water, groundwater, roof runoff, subsurface drainage, or other unpolluted water, nor drain any catch basin, lake, swamp, or pond, except with the permission of the Director of Public Works evidenced by a properly issued permit or if such connection or drainage is into a designated combined sewer or storm sewer. Cooling water discharges to the waters of the state require SPDES permits and are subject to state and federal regulations.
A. 
No user shall contribute or cause to be contributed, in any manner or fashion, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of the POTW. These general prohibitions apply to all such users of a POTW whether or not the user is subject to National Categorical Pretreatment Standards, or any other national, state, or local pretreatment standards or requirements.
B. 
Without limiting the generality of the foregoing, a user may not contribute the following substances to the POTW:
(1) 
Any solids, liquids, or gases which, by reason of their nature or quantity, are or may be sufficient, either alone or by interaction with other substances, to cause a fire or an explosion or be injurious, in any way, to the POTW, or to the operation of the POTW. At no time shall both of two successive readings on a flame-type explosion hazard meter, at the point of discharge into the system (or at any other point in the system) be more than 25% nor any single reading be more than 40% of the lower explosive limit (LEL) of the meter. Unless explicitly allowable by a written permit, prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, carbides, hydrides, and sulfides, and any other substance which the City, the state, or the EPA has determined to be a fire hazard, or hazard to the POTW.
(2) 
Solid or viscous substances which may cause obstruction to the flow in a sewer or otherwise interfere with the operation of the wastewater treatment facilities. Unless explicitly allowable by a written permit, such substances include, but are not limited to, grease, garbage with particles greater than 1/2 inch in any dimension, animal guts or tissues, paunch manure, bones, hair, hides or fleshing, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, wood, plastics, gas, tar asphalt residues, residues from refining or processing fuel or lubricating oil, mud, or glass or stone grinding or polishing wastes.
(3) 
Any wastewater having a pH less than 5.5 or greater than 10.0, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment, and/or POTW personnel.
(4) 
Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants (including heat), to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the POTW, or to exceed the limitation set forth in a Categorical Pretreatment Standard. A toxic pollutant shall include, but not be limited to, any pollutant identified pursuant to Section 307(A) of the Act.
(5) 
Any noxious or malodorous solids, liquids, or gases which either singly or by interaction with other wastes are sufficient to create a public nuisance or a hazard to life or are sufficient to prevent entry into the sewers for their maintenance or repair.
(6) 
Oils and grease. Any commercial, institutional, or industrial wastes containing fats, waxes, grease, or oils which become visible solids when the wastes are cooled to 10° C. (50° F.); any petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in excess of 100 mg/l or in amounts that will cause interference or pass-through.
(7) 
Any wastewater which will cause interference or pass-through.
(8) 
Any wastewater with objectionable color which is not removed in the treatment process, such as, but not limited to, dye wastes, and vegetable tanning solutions.
(9) 
Any solid, liquid, vapor, or gas having a temperature higher than 65° C. (150° F.); however, such materials shall not cause the POTW treatment plant influent temperature to be greater than 40° C. (104° F.). The Director of Public Works reserves the right, in certain instances, to prohibit or limit the discharge of wastes whose maximum temperatures are lower than 65° C.
(10) 
Any pollutant, including oxygen-demanding pollutants (BOD, etc.) released in a discharge at a flow rate and/or pollutant concentration which will cause interference with the POTW.
(11) 
Any wastewater containing any radioactive wastes except as approved by the Director of Public Works, and in compliance with applicable state and federal regulations.
(12) 
Any wastewater which causes a hazard to human life or which creates a public nuisance, either by itself or in combination, in any way, with other wastes.
(13) 
Any wastewater with a closed cup flashpoint of less than 140° F. or 60° C. using the test methods specified in 40 CFR § 261.21.
(14) 
Any pollutants which result in the presence of toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems.
(15) 
Any trucked or hauled pollutants, except at discharge points designated by the POTW.
No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes or any wastes listed within the rules and regulations found to harm the sewerage system structures, the sewage treatment process or would endanger life, limb, public property or constitute a nuisance. The criteria used in forming these rules and regulations include such factors as the quantities of said wastes in relation to flows and velocities in the sewers, materials or construction of the sewers, nature of the sewage treatment process, the capability 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 Director of Public Works are:
A. 
Any garbage that has not been properly shredded or triturated.
B. 
Any water or wastes containing phenols or other taste- or odor-producing substances, in such concentrations exceeding limits which shall be established in the rules and regulations to meet the requirements of the state, federal or other public agencies of jurisdiction for such discharge to the receiving waters.
C. 
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 sulfate).
(2) 
Except as provided for under Article X, 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.
D. 
Pretreatment standards. All users of the City's POTW will comply with all standards and requirements of the Act and standards and requirements promulgated pursuant to the Act, including but not limited to 40 CFR Chapter I, Subchapter N.
The Director of Public Works, after a hearing, shall either prevent the discharge of unacceptable water and wastes or issue a permit and compliance schedule which is properly conditioned upon findings and the standards of safety prescribed by this chapter and rules and regulations. This chapter and rules and regulations shall include surcharges, pretreatment requirements, control over quantities or rates of discharge, time of discharge and holding facilities, and any measure or combination of measures which are necessary to preserve the sewerage system, its structures and equipment, and the health, safety and well-being of the employees, the community and the biota of the receiving waters.
The Director of Public Works shall take any temporary action necessary to protect the public health, safety or welfare without a prior hearing in the event of any discharge which, in the belief of the Director of Public Works, will cause serious, imminent harm, injury or adversely affect the sewerage system structures, equipment, any person, or the biota of the receiving waters. If possible, under the circumstances of the emergency, the Director of Public Works will give informal notice of his emergency action to the affected party. Review of any emergency action by a hearing will be accomplished without delay to determine what, if any, permanent restriction is necessary. The Director of Public Works, 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, welfare or property of the City of Canandaigua.
