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 wastewater treatment 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 opinion as to the acceptability of these wastes, the wastewater treatment 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 maximum limits established by regulatory agencies. The substances prohibited are:
(A) Any liquid or vapor having a temperature higher than one hundred fifty degrees Fahrenheit (150°F) (60°C).
(B) Any waters or wastes containing toxic or poisonous material; or oils, whether emulsified or not, in excess or one hundred milligrams per liter (100 mg/l) or containing substances which may solidify or become viscous at temperatures between thirty two degrees (32°) and one hundred fifty degrees Fahrenheit (150°F) (0° and 65°C).
(C) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths (3/4) horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the wastewater treatment superintendent.
(D) Any waters or wastes containing strong acid, iron pickling wastes, or concentrated plating solution, whether neutralized or not.
(E) Any waters or wastes containing iron, chromium, copper, zinc, or 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 wastewater treatment superintendent for such materials.
(F) Any waters or wastes containing phenols or other taste or odor producing substances, in such concentrations exceeding limits which may be established by the wastewater treatment 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.
(G) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the wastewater treatment superintendent in compliance with applicable state or federal regulations.
(H) Any wastes or waters having a pH in excess of nine and five-tenths (9.5).
(I) Any mercury or any of its compounds in excess of 0.0005 mg/l as Hg at any time except as permitted by the wastewater treatment superintendent in compliance with applicable state and federal regulations.
(J) Any cyanide in excess of 0.025 mg/l at any time except as permitted by the wastewater treatment superintendent in compliance with applicable state and federal regulations.
(K) 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 waste and vegetable tanning solutions);
3. Unusual BOD, 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 concentrations of wastes constituting "slugs" as defined herein.
(L) 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 effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters. (Ord. 1268, 12-5-1989)
(M) Any ground water or surface water which is collected in an effort to remediate ground water which has been contaminated with petroleum hydrocarbons which will exceed the following limitations:
1. | Benzene | 0.5 ppm | ||
2. | Toluene | 0.5 ppm | ||
3. | Ethyle Benzene | 0.5 ppm | ||
4. | Xylene | 0.5 ppm | ||
5. | n-Hexane | 0.5 ppm | ||
6. | 1,2 Dichlorobenzene | 0.5 ppm | ||
7. | 1,3 Dichlorobenzene | 0.5 ppm | ||
8. | 1,4 Dichlorobenzene | 0.5 ppm | ||
9. | Lead | 5.81 ppm | ||
10. | pH | Between 5 and 11 | ||
11. | Total of items 1 through 8 | 4.0 ppm | ||
In addition to the above limits, the discharge must not be hazardous as defined by the hazardous waste characterization analysis for constituents as listed under 35 IAC part 721, subpart C. The analysis results must be submitted. The waste must not contain or exceed the following limits: | ||||
12. | Flashpoint | <140° Fahrenheit | ||
13. | pH | Limited above | ||
14. | No reactive chemicals capable of producing toxic gases. | |||
15. | Must pass the toxic characteristics leaching procedure (TCLP). | |||
Also, any discharge system shall include, at a minimum, an oil water separator. This requirement may be waived by the wastewater treatment superintendent if other devices such as skimmer pumps, settling basins, or surge tanks are in use.
The applicant should note that an indemnification statement relieving the city of all liability for the operation and discharges of the ground water remediation system is required. The indemnification statement shall be included with the permit application. (Ord. 1478, 8-1-1995)
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 8-19-31 of this article, and/or which are in violation of the standards for pretreatment provided in 40 CFR 403, June 26, 1978, and any amendments thereto, and which in the judgment of the wastewater treatment 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 wastewater treatment superintendent may:
(A) Reject the wastes; or
(B) Require pretreatment to an acceptable condition for discharge to the public sewers; or
(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 8-19-11 of this chapter. If the wastewater treatment 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 wastewater treatment superintendent, and subject to the requirements of all applicable codes, ordinances, and laws. (Ord. 1268, 12-5-1989)
Grease, oil, and sand interceptors shall be provided when, in the opinion of the wastewater treatment 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 that 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 wastewater treatment superintendent and shall be located as to be readily and easily accessible for cleaning and inspection. (Ord. 1268, 12-5-1989)
Each industry shall be required to install a control manhole and, when required by the wastewater treatment 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 wastewater treatment superintendent. The manhole shall be installed by the owner at his expense, and shall be maintained by him so as to be safe and accessible at all times. (Ord. 1268, 12-5-1989)
(A) The owner of any property serviced by a building sewer carrying industrial wastes shall provide laboratory measurements, tests, and analyses of waters and wastes to illustrate compliance with this chapter and any special conditions for discharge established by the city or regulatory agencies having jurisdiction over the discharge.
(B) The number, type, and frequency of laboratory analyses to be performed by the owner shall be as required by the city, but no less than once per year the industry must supply a full and complete analysis of the constituents of the wastewater discharge to assure that compliance with the federal, state, and local standards are being met. The owner shall report the results of measurements and laboratory analyses to the city at such times and in such a manner as prescribed by the city. The owner shall bear the expense of all measurements, analyses, and reporting required by the city. At such times as deemed necessary the city reserves the right to take measurements and samples for analysis by an outside laboratory service. (Ord. 1268, 12-5-1989)
(C) The city is not required to accept any remediation waters if samples have not been tested or if the testing reflects levels not acceptable under subsection 8-19-31(M) of this article. (Ord. 1454, 3-7-1995)
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 IEPA division of laboratories manual of laboratory methods, 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 by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence 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 pH's are determined from periodic grab samples. (Ord. 1268, 12-5-1989)
