(3) Any waters or wastes having a pH less than 6.6 or greater than 8.5 or containing heavy concentrations of salts or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works; and
(4) Solids or viscous substances in quantities or of a size capable of causing obstruction in the flow of sewage or other interference to 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, wood, unground garbage, manure, hair and fleshing, or entrails and paper dishes, cups, mild containers and the like either whole or ground by garbage grinders.
(1982 Code, Ch. 8, Art. IV, § 5-2)
(C) 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 town, that such wastes can harm either the sewers, sewage treatment process or equipment having adverse effect on the receiving stream or can otherwise endanger life, limb, public property or constitute a nuisance. In forming their opinion as to the acceptability of these wastes, the town will give consideration to such factors 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 plant and other pertinent factors. The substances prohibited are:
(1) Any liquid or vapor having a temperature higher than 150°F or 65°C;
(2) Any water or waste containing fats, wax, grease or oils whether emulsified or not in excess of 100 mg/1 or containing substances which may solidify or become viscous at temperatures between 32°F and 150°F or 0°C and 65°C;
(3) Any garbage that has not been properly shredded; (The installation and operation of any garbage grinder equipped with a motor of 3/4 hp. or greater shall be subject to the review and approval of the town.)
(4) Any waters or wastes containing strong acid, iron pickling wastes or concentrated plating solutions whether neutralized or not;
(5) Any waters or wastes containing heavy metals in excess of the following:
Chromium | 1.0 mg/1 (either III or VI or in combination) |
Lead | 2.0 mg/1 |
Tin | 2.0 mg/1 |
Zinc | 2.0 mg/1 |
Copper | 0.5 mg/1 |
Nickel | 1.0 mg/1 |
Cyanide | 2.0 mg/1 |
or combination of the above in excess of 9.0 mg/1 in the effluent, or which when blended with the waste in the trunk line will have a concentration in excess of 1.0 mg/1 when it reaches the treatment plant, division (D) below not withstanding, or wastes exerting an excessive chlorine requirement to such a degree that any such material received in composite sewage at the sewage treatment works exceeds the limits established by the town 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 town as necessary after treatment of the composite sewage to meet requirements to the state, federal and other public agencies of jurisdiction of such discharge of the receiving waters;
(7) Any radioactive waste or isotopes of such half life or concentration as may exceed limits established by the town in compliance with applicable state and federal regulations;
(8) Any waters or wastes having a pH outside of the range of 6.5 to 8.5;
(9) Materials which exert or cause:
(a) Unusual concentration 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, chemical oxygen demand or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works; and/or
(d) Unusual volume of flow of concentrations of wastes constituting sludge 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 amenable to treatment only to such degree that the sewage treatment plant: cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
(1982 Code, Ch. 8, Art. IV, § 5-3)
(D) (1) 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 division (C) above, which in the judgment of the town may have a deleterious act upon the sewage works, processes, equipment or receiving water, or which otherwise create a hazard to life or constitute a public nuisance, the town may:
(a) Reject wastes;
(b) Require pretreatment to an acceptable condition with discharge to the public sewers;
(c) Require control over the quantities and rates of discharge; and/or
(d) Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges, under the provisions of division (I) below.
(2) If the town permits the pretreatment or equalization of waste flows, the design and installation of the plant and equipment shall be subject to the review and approval of the town subject to the requirements of all applicable codes, ordinances and laws.
(1982 Code, Ch. 8, Art. IV, § 5-4)
(E) (1) Grease, oil and sand interceptors shall be provided when, in the opinion of the town, 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 that the interceptors shall not be required for private living quarters or dwelling units.
(2) All interceptors shall be located as to be readily and easily accessible for cleaning and inspection.
(3) All interceptors shall be supplied and properly maintained continuously in satisfactory and effective operation by the owner at his or her expense.
(1982 Code, Ch. 8, Art. IV, § 5-5)
(F) Where preliminary treatment for flow equalizing facilities is provided for any waters, or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
(1982 Code, Ch. 8, Art. IV, § 5-6)
(G) (1) It shall be required by the town that the owner of any property serviced by a building sewer carrying industrial wastes install a suitable control manhole. When deemed necessary, the town may require additional meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the waste.
(2) The manhole shall be accessible and safely located and shall be constructed in accordance with plans approved by the town. The manhole shall be installed by the owner at his or her expense and shall be maintained by him or her so as to be safe and accessible at all times.
(1982 Code, Ch. 8, Art. IV, § 5-7)
(H) (1) All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the latest edition of Standard Methods for Examination of Water and Waste Water, published by the American Public Health Association, and shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence or hazards to life, limb and property.
(2) In order for the town to properly evaluate the effect of the waste on the system, an industry must submit, along with the plan and the like, required in § 54.03, an industrial waste questionnaire form. These forms are available from the town.
(1982 Code, Ch. 8, Art. IV, § 5-8)
(I) No statement contained in this section shall be construed as preventing any agreement or arrangement between the town and any industrial concern whereby industrial waste of unusual strength or character may be accepted by the town for treatment, subject to payment therefor by the industrial concern. The table which follows is the basis on which sewer surcharges shall be assessed for the treatment of industrial and/or unusual strength or characteristic waste.
