5. Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions, whether neutralized or not;
6. 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 plant exceeds the limits established by the director for such materials;
7. Any waters or wastes containing phenols or other waste or odor producing substances, in such concentrations exceeding limits which may be established by the director 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;
8. Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the director in compliance with applicable state or federal regulations;
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, chemical oxygen demand, 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 wastes constituting slugs as defined herein;
10. Those pesticides and other toxic pollutants in toxic amounts, as determined by the administrator of the environmental protection agency in accordance with the federal act, such other federal or state act as may be applicable and as further designated from time to time by the director, including the following substances or materials containing these substances:

13. Discharges prohibited by the environmental protection agency regulations promulgated under the federal act.
(M) If the 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 subsection (C) of this section, and which, in the judgment of the director, 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 director 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 sewer charges under the provisions of subsection (J) of this section. If the director 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 director, and subject to the requirements of all applicable codes, ordinances and laws.
(N) 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 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 said 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 in the customarily accepted methods to reflect the effect of constituents upon the sewer works and to determine the existence of hazards to life, limb and property.
(O) It shall be unlawful for any person to wilfully break, damage, destroy, uncover, deface, or tamper with any sewer, structure, appurtenance, or equipment which is a part of the sewerage system of the city. Any violation shall be subject to penalty section 1-4-5 of this code. (Ord. 1646, 5-8-2012)
