No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(A) Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas. Remediation waters from leaking underground storage tanks or surface spills may be allowed provided that the same do not exceed the limits of subsection 8-19-31(M) of this chapter.
(B) 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.
(C) 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.
(D) 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, wood, 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. 1268, 12-5-1989; amd. Ord. 1454, 3-7-1995)
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)
