Any waters or wastes containing a toxic, poisonous or radioactive substance in sufficient quantity to injure or interfere with any sewage treatment process or to constitute a hazard to humans, animals or marine life, or create any hazard in the receiving wastes. Radioactive wastes or materials may be discharged into a public sewer if Conditions I and II below are met and if either Condition III or IV is also met, provided that such discharges are in compliance with applicable state or federal regulations:

(1)

Condition I. Such wastes must be readily soluble or dispensable in water.

(4)

Condition IV. Daily quantities of radioactive materials up to the maximum permitted by the United States Atomic Energy Commission may be so discharged provided that the total monthly quantities, if diluted by the average monthly volume of sewage discharged from the installation, do not exceed the concentrations permissible under Condition III above.

Any waters, sewage or wastes having a pH lower than 5.0 or higher than 9.5, or having any other corrosive or detrimental property capable of causing damage or hazard to the sewage works or personnel.

Any noxious, malodorous or taste-producing gas, vapor or substance, such as phenols, capable of creating a public or private nuisance or which may prove toxic to sewage treatment processes or which may exceed acceptable limits for discharge to receiving waters.

Any water containing iron, copper chromium, zinc and similar objectionable toxic substances.

(3)

Toxic substances and pathogenic bacteria. The following is a partial list of toxic substances and pathogenic bacteria, the discharge of which into the village sewer system or public sewers tributary thereto is hereby prohibited unless their concentration is reduced by treatment at the source to a point that will meet the general purposes of these rules, regulations and ordinances or come within the applicable standards set forth herein, and will not adversely affect any of the biochemical, chemical or other sewage treatment processes:

[Added 9-25-1972]

(n)

Strong reducing agents such as nitrites, sulfides, sulfites thiosulfates, etc.

(o)

Wastes from industrial processes or hospital procedures containing viable pathogenic organisms.

(4)

Permissible concentration of toxic substances. The concentration in sewage of any of the following toxic substances shall not exceed these concentrations judged by the Superintendent to be toxic to biological sewage treatment processes or to the biota of the receiving waters and shall not exceed the limits specified below when they are discharged to the sewer. These limits may be revised by the Superintendent whenever in his opinion operating experience so indicates:

[Added 9-25-1972]

Toxic Substances	Permissible Concentration (milligrams per liter)
Cadmium	5.0
Chromium hexavalent	5.0
Copper	3.0
Cyanate	10.0
Cyanide	1.0
Mercuric chloride	2.0
Nickel	10.0
Silver	0.05
Zinc	5.0

Bromide, iodine, chlorine	100.0

Materials which exert 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)

Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions).

(3)

Unusual BOD, suspended solids, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.

(4)

Unusual volume of flow or concentration of wastes constituting "slugs" as defined herein.

Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment process employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.

§ 269-10 In case of violation.

If any waters or wastes are discharged, or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in § 269-9 and which may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the village may:

(1)

Reject the wastes.

(2)

Require pretreatment to an acceptable condition for discharge to the public sewers.

(3)

Require control over the quantities and rates of discharge, and/or

(4)

Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges.

If the village permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the village and of any or all state regulatory agencies having jurisdiction, and no construction of such facilities shall be commenced until said approvals are obtained in writing.

§ 269-11 Determination of exclusion of wastes.

In determining whether any waste discharged or proposed to be discharged into any public sewer is to be excluded, consideration will be given to the quantity, time or times, rate and manner of discharge, dilution and character of the waste in question, the size of the sewer into which the waste is to be discharged, the probable quantity of sewage or other wastes likely in said sewer, and other pertinent facts. Minute quantities of a waste which would be objectionable in larger quantity may be accepted if sufficiently diluted when and as discharged or if the quantity discharged is small as compared with the flow in the receiving sewer; but any permission to discharge minute quantities of all otherwise excluded waste shall be revocable at any time by the village.

§ 269-12 Pretreatment facilities.

At all premises where wastes or substances specified to be excluded from public sewers by these regulations are present and liable to be discharged directly or indirectly into said sewers, suitable and sufficient piping layouts, oil, grease, sand and flammable waste traps or separators, screens, settling tanks, diluting devices, storage or regulating chambers, treatment, cooling or other equipment and devices shall be provided. These shall be maintained and properly operated by the owner of the premises or his agent at his expense to insure that no waste or substance is discharged in violation of the requirements of these regulations.

On premises where wastes or substances specified to be excluded from public sewers are present, the village may require the owner to provide, operate and maintain at his expense a sampling well or wells, flow-measuring devices, manholes or other appurtenances, all readily accessible, on the building sewer or drain from said premises near the point where said sewer or drain connects to the public sewer. By means of said sampling well or wells, flow-measuring devices, or other appurtenances, the village or any public officer having legal jurisdiction, may secure samples of, or examine the wastes being discharged into the public sewer for the purpose of determining compliance or noncompliance with the requirements of these regulations.

The village shall have the right to enter and inspect any part of the premises served by public sewers upon which there may be reason to believe that violations of the requirements of these regulations have occurred or are likely to occur for the purpose of ascertaining the facts as to such violation or suspected violation, or of obtaining samples of wastes, or of inspecting flow-measuring devices or treatment facilities provided to prevent prohibited discharges.

§ 269-13 Storm sewer exclusions.

No waste waters or substances which are excluded from sanitary sewers shall be discharged into any storm sewer.

§ 269-14 Tests and manholes.

All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this section shall be determined in accordance with "Standard Methods For the Examination of Water and Sewage." In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected.

§ 269-15 Industrial exceptions.

No statement contained on this section shall be construed as preventing any special agreement or arrangement between the village and any industrial concern whereby an industrial waste of unusual strength of character may be accepted by the village for treatment, subject to payment therefore by the industrial concern.
