§ 26-265. Prohibited discharge; industrial waste.

(a)

In addition to the prohibitions stated in section 26-263; 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 Village Engineer 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 an opinion as to the acceptability of these wastes, the Village Engineer 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, and maximum limits established by regulatory agencies. The substances described herein are:

(1)

Any liquid or vapor having a temperature higher than 150 degrees Fahrenheit.

(2)

Any waters or wastes containing toxic or poisonous materials; or oils, whether emulsified or not, in excess of 100 mg/L or containing substances which may solidify or become viscous at temperatures between 32 and 150 degrees Fahrenheit.

(3)

Any garbage that has not been properly shredded.

(4)

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

(5)

Any waters or wastes having a pH in excess of 9.5.

(6)

Any mercury or any of its compounds in excess of 0.0005 mg/L as Hg at any time in compliance with applicable state and federal regulations.

(7)

Any cyanide in excess of 0.025 mg/L at any time.

(8)

Materials which exert or cause:

a.

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 and sodium sulfite);

b.

Excessive discoloration (such as, but not limited to, dyewastes and vegetable tanning solutions);

c.

Unusual biological, 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 concentrations of wastes constituting of "slugs" as defined herein.

(9)

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.

(10)

Water or wastes which are prohibited by any regulations of the Metropolitan Water Reclamation District of Greater Chicago.

(b)

If any waters or wastes are discharged or are proposed to be discharged into the public sewers, which waters contain the substances or possess the characteristics enumerated in this section, and/or which are in violation of the U.S. EPA and MWRD standards for pretreatment provided in Chapter 1, EPA Rules and Regulations, subchapter D, Water Programs part 128, Pretreatment Standards, Federal Register Volume 38, No. 215, Thursday, November 8, 1973, and any amendments thereto, and which in the judgment of the village may have a deleterious effect upon the sewage works, process, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the village may:

(1)

Reject the wastes;

(2)

Require pretreatment to an acceptable condition for discharge to the public sewers (The design and installation of the plants and equipment shall be subject to the review and approval of the Director of Engineering and Public Works, and subject to the requirements of all applicable codes, ordinances, and laws.);

(3)

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

(4)

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 this article.

(c)

If the village 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 village, and subject to the requirements of all applicable codes, ordinances, and laws.
