[Ord. No. 2005-24 §1(13.0502), 8-2-2005]
A. 
No person shall discharge or cause to be discharged any of the following described waters or wastes into any public sewers:
1. 
Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas.
2. 
Any waters or wastes containing toxic or poisonous solids, liquids, or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of the sewage treatment plant including, but not limited to, cyanides in excess of two (2) mg/l as CN in the wastes as discharged to the public sewer.
3. 
Any waters or wastes having a pH lower than five and five-tenths (5.5), or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works.
4. 
Solid or viscous substances in quantities, or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, woods, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.

[Ord. No. 2005-24 §1(13.0503), 8-2-2005]
A. 
No person shall discharge or cause to be discharged the following described substances, materials, waters, or wastes if it appears likely in the opinion of the Superintendent such wastes can harm either the sewers, sewage treatment process, or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property, or constitute a nuisance. In forming his/her opinion as to the acceptability of these wastes, the Superintendent will give consideration to such facts as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant, and other pertinent factors. The substances prohibited are:
1. 
Any liquid or vapor having a temperature higher than one hundred fifty degrees Fahrenheit (150°F) (sixty-five degrees Centigrade (65°C)).
2. 
Any water or waste containing fats, wax, grease, or oils, whether emulsified, in excess of one hundred (100) mg/l or containing substances which may solidify or become viscous at temperatures between thirty-two degrees Fahrenheit (32°F) and one hundred fifty degrees Fahrenheit (150°F) (zero (0) and sixty-five degrees Centigrade (65°C)).
3. 
Any garbage not properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths (¾) horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Superintendent.
4. 
Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized.
5. 
Any waters or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Superintendent for such materials.
6. 
Any waters or wastes containing phenols or other taste- or odor-producing substances in such concentrations exceeding limits which may 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 of jurisdiction for such discharge to the receiving waters.
7. 
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.
8. 
Any waters or wastes having a pH in excess of nine and five-tenths (9.5).
9. 
Materials which exert or cause:
a. 
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).
b. 
Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions).
c. 
Unusual BOD, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
d. 
Unusual volume of flow or concentration of waters constituting "slugs" as defined herein.
10. 
Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amendable 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.
[Ord. No. 2005-24 §1(13.0504), 8-2-2005]
A. 
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 this Chapter and which in the judgment of the Superintendent 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 Superintendent 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 costs of handling and treating wastes not covered by existing taxes or sewer charges under the provisions of this Chapter.
5. 
Require pretreatment maintenance program assuring acceptable condition for discharge.
6. 
Terminate all utility services as provided in this Code.
B. 
If the Superintendent 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 Superintendent, and subject to the requirements of all applicable codes, ordinances, and laws.
[Ord. No. 2005-24 §1(13.0505), 8-2-2005]
Grease, oil, and sand interceptors shall be provided when in the opinion of the Superintendent they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand, or other harmful ingredients; except such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Superintendent and shall be located as to be readily and easily accessible for cleaning and inspection.
[Ord. No. 2005-24 §1(13.0507), 8-2-2005]
When required by the Superintendent, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling, and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Superintendent. The manhole shall be installed by the owner at his/her expense, and shall be maintained by him/her so as to be safe and accessible at all times.
[Ord. No. 2005-24 §1(13.0508), 8-2-2005]
All measurements, tests, and analyses of the characteristics of water and wastes to which reference is made in this Chapter shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater" published by the American Public Health Association, and shall be conducted at the control manhole provided, or upon suitable samples taken at said control manhole. In the event no special manhole has been required, the control shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards of life, limb, and property. (The particular analyses involved will determine whether a twenty-four (24) hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from twenty-four (24) hour composites of all outfalls whereas pHs are determined from periodic grab samples.)
