15-426 Same; determination of superintendent.

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 that 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 or her opinion as to the acceptability of these wastes, the superintendent 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 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:

(a)Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized or not.

(b)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 wastewater at the wastewater treatment works exceeds the limits established by the superintendent for such materials.

(c)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 state, federal, or other public agencies of jurisdiction for such discharge to the receiving waters.

(d)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.

(e)Materials which exert or cause:

(1)Unusual concentrations of inert suspended solids (such as, but not limited to, Fullers earth, lime slurries, and lime residues) or of dissolved solids (such as, but not limited to sodium chloride or sodium sulfate).

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

(3)Unusual BOD, chemical oxygen, demand, or chlorine requirements in such quantities as to constitute a significant load on the sewer treatment works,

(4)Unusual volume of flow or concentration of wastes constituting slugs as defined herein.

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

(g)Any waters or wastes having

(1)a five-day BOD greater than 300 parts per million by weight, or

(2)containing more than 350 parts per million by weight or suspended solids, or (3) having an average daily flow greater than two percent of the average wastewater flow of the city, shall be subject to the review of the superintendent. Where necessary in the opinion of the superintendent, the owner shall provide, at his or her expense, such preliminary treatment as may be necessary to (1) reduce the biochemical oxygen demand to 300 parts per million by weight, or (2) reduce the suspended solids to 350 parts per million by weight, or

(3)control the quantities and rates of discharge of such waters or wastes. Plans, specifications, and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the superintendent and no construction of such facilities shall be commenced until the approvals are obtained in writing.

(Ord. 543; Code 1998)

15-427 Same; action of superintendent.

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 section 15-426, and which in the judgment of the superintendent, may have a deleterious effect upon the treatment works, processes, equipment, or receiving waters, or which otherwise create a hazard to life to constitute a public nuisance, the superintendent may:

(a)Reject the wastes;

(b)Require pretreatment to an acceptable condition for discharge to the public sewers;

(c)Require control over the quantities and rates of discharge; and/or

(d)Require payment to cover the added costs of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of section 15-428.

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. 543; Code 1998)

15-428 Preliminary treatment.

Where preliminary treatment for flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.

(Ord. 543; Code 1998)

15-429 Industrial wastes.

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 or her expense, and shall be maintained by him or her so as to be safe and accessible at all times. All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this article 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 determined at the control manhole provided, or upon suitable samples taken at the control manhole. 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. 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 to life, limb and property. (The particular analyses involved will determine whether a 24 hour composite of all outfalls of a premise is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from 24 hour composites of all outfalls whereas pH’s are determined from periodic grab samples.)

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

(Ord. 543; Code 1998)

15-430 City inspections.

(b)While performing the necessary work on private properties referred to above, the superintendent or duly authorized employees of the city shall observe all safety rules applicable to the premises established by the company and the company shall be held harmless for injury or death to the city employees and the city shall indemnify the company against loss or damage to its property by city employees and against liability claims and demands for personal injury or property damage asserted against the company and growing out of the gauging and sampling operation, except as such may be caused by negligence or failure of the company to maintain safe conditions as required in section 15-429.

(c)The superintendent and other duly authorized employees of the city bearing proper credentials and identification shall be permitted to enter all private properties where any portion of the treatment works or wastewater system is located for the purpose of but not limited to inspection, observation, measurement, sampling, repair and maintenance of any portion of the treatment works lying within the private property.
