Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I).
Stormwater and all other unpolluted drainage shall be discharged to such sewers as approved by the Superintendent. Industrial cooling water or unpolluted process waters may be discharged, on approval of the Superintendent, to a storm sewer or natural outlet.
No person shall discharge or cause to be discharged the following described substances, materials, waters, or wastes to any public sewers:
A. 
Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid or gas.
B. 
Any waters or wastes containing toxic or poisonous solids, liquids, or gases in sufficient quantity, either singly or by interaction with other processes, to constitute a hazard to animals, create any hazard in the receiving waters of the sewer treatment plant, or to cause the effluent from the treatment works to violate applicable effluent standards.
C. 
Any waters or wastes having a pH lower than 6.0 or having any other corrosive property capable of causing damage or hazard to structure, equipment, and personnel of the sewage works.
D. 
Solids 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 no 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 disposal.
No person shall discharge or cause to be discharged the following described substances, material, waters, or wastes to any public sewers 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, as determined in the NPDES permit received by the City, or otherwise endanger life, limb, public property, or constitute a nuisance. In forming his opinion as to the acceptability of these wastes, the Superintendent, in consultation with the City Engineer, operator of the treatment plant and the state regulatory agency, will give consideration to such factors as velocities in the sewer, materials of construction of the sewage treatment plant, and maximum limits established by regulatory agencies. The substances prohibited, including all limitations and prohibitions imposed by the NPDES permit of the City, are:
A. 
Any liquid or vapor having a temperature higher than 150° F. (65° C.).
B. 
Any water or waste containing fats, toxic or poisonous materials, wax, grease 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° F. and 150° F. (0° C. and 65° C.).
C. 
Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with the motor of 3/4 horsepower (0.76 horsepower) metric or greater shall be subject to the review and approval of the Superintendent.
D. 
Any waters and wastes containing strong acid iron pickling wastes or concentrated plating solutions, whether neutralized or not.
E. 
Any waters or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances beyond the maximum allowable concentrations as determined by the Superintendent.
(1) 
The Superintendent will evaluate each toxic or objectionable substance waste on a concentration-dilution basis and will establish maximum allowable discharge concentrations for each individual person to protect against the following:
(a) 
Decreased sewage plant treatment process efficiencies and degraded effluent qualities exceeding the current requirements of the regulatory agencies.
(b) 
Concentrations of any toxic or objectionable substances in the sewage treatment plant effluent exceeding the current maximum limits established by the regulatory agencies for such plant effluent flows.
(c) 
Any concentrations of toxic or objectionable substances in plant effluent flows which will result in concentrations of such substances in the receiving waters which will exceed the regulatory agency's maximum allowable limits for these substances in the receiving water.
(2) 
Unless otherwise authorized by the Superintendent, the maximum acceptable concentration of certain substances in the waste discharged to the City sewer shall not exceed the following limitations:
Waste and Chemical
Concentrations
(mg/l)

The application shall contain sufficient information on discharge concentrations, flows, etc., to provide adequate data to enable the City and its representative to evaluate the discharge and secure required Illinois Environmental Protection Agency approval.
(2) 
When permitted, total cyanide shall not exceed 10 mg/l, provided any sample tested shall not release more than two mg/l of cyanide when tested at a pH of 4.5 at a temperature of 150° F. for a period of 30 minutes. Such discharge shall be permitted only when the Agency has determined that no violation of the effluent criteria of 0.1 mg/l concentration (alone or in combination with other sources) will result from such discharge.
H. 
Any waters or wastes containing phenols or other waste- 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 the state, federal or other public agencies of jurisdiction for such discharge to the receiving waters. Unless otherwise authorized by the Superintendent, the maximum acceptable concentrate of phenols in waste discharge to the City sewer shall be 0.5 mg/l.
I. 
Any radioactive wastes or isotopes of such half-life concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations.
J.

L. 
Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters, including the NPDES permit of the City.
A. 
If any waters or wastes are discharged, or are proposed to be discharged to the public sewers, which waters containing the substances or possess the characteristics enumerated in § 245-31, and/or which are in violation of the standards for pretreatment provided in Chapter 1, EPA Rules and Regulations, Subchapter D, Water Programs, Part 129, Pretreatment Standards, Federal Register Volume 38, No. 215, Thursday, November 8, 1973, and amendments thereto, and which in the judgment of the 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 Superintendent may:
(1) 
Reject the wastes and require the violator to cease and desist discharging said materials into the sewer system immediately.
(2) 
Require pretreatment to an acceptable condition for discharge to the public sewers.
(3) 
Require control over the quantities and rates of discharge and also require payment to cover the added costs of handling and treating the wastes not covered by the existing sewer charges.
B. 
If the City permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to review and approval of the City and the Illinois EPA in accordance with Code of Federal Regulations 40 CFR 403, entitled "Pre-Treatment Standards," and all other ordinances and codes pertaining thereto.
A. 
Grease, oil and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand, or other material; 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 Superintendent and shall be located so as to be readily and easily accessible for cleaning and inspection.
B. 
Grease interceptors shall be provided by the property owner (tenant) in any building or facility serving food to the public, including, but not limited to, schools, clubs, nursing homes, eating establishments, and any other public facilities serving food to the public.
C. 
Said interceptor shall be installed to protect the City sewer system from grease in excessive amounts. An interceptor shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Superintendent and shall be located so as to be readily and easily accessible for cleaning and inspection.
Each new industry shall be required to install a control manhole; and when required by the Superintendent, the owner of any property serviced by an existing building sewer carrying industrial or commercial 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 expense and shall be maintained by him so as to be safe and accessible at all times.
A. 
The owner of any property serviced by a building sewer carrying industrial wastes shall provide laboratory measurements, tests, and analyses of water and wastes to illustrate compliance with this chapter and any special conditions for discharge established by the City and 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 stipulated by the City; but no less than once a year, the industry must supply a complete analysis of the constituents of the wastewater discharge to assure that compliance with the federal, state and local standards is being met. The owner shall report the results of measurements and laboratory analyses to the City at such time and in such manner as prescribed by the City. The owner shall bear the expense of all measurements, analyses, and reporting required by the City. At such time as deemed necessary, the City reserves the right to take measurements and samples for analysis by an outside laboratory service.
[Amended by Ord. No. 10-01-07]
A. 
Measurements, tests and analysis of the characteristics of water 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 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 analysis involved will determine whether a twenty-four-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-hour periodic grab samples.)
B. 
Any person discharging wastes having concentrations greater than the "normal" concentrations as set forth herein shall, upon notification by the City, install a composite sampler with a compatible pacing (metering) device for monitoring said substances. The pacing and sampling devices shall be of a type approved by the Superintendent. All testing and measuring procedures for the analysis of pollutants shall be in conformance with 40 CFR Part 136.
C. 
The cost of all required measurements, tests and analyses shall be borne by the contributor.
No statement contained in this article shall be construed as preventing any special agreement or arrangement between the City of Mendota and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the City for treatment, subject to payment therefor, in accordance with the provisions of this chapter, by the industrial concern, provided such payments are in accordance with federal and state guidelines for user charge system and industrial cost recovery system.
No unauthorized person shall maliciously, willfully, or negligently break, damage, destroy, uncover, deface, or tamper with any structure, appurtenance, or equipment which is a part of the sewage works. Any person violating this provision shall be subject to immediate arrest under a charge of disorderly conduct.
The Superintendent and other duly authorized employees of the City, the Illinois Environmental Protection Agency, and the United States Environmental Protection Agency, bearing proper credentials and identification, shall be permitted to enter all properties for the purposes of inspection, observation, measurements, sampling, and testing in accordance with the provisions of this chapter. The Superintendent or his representative shall have no authority to inquire into any processes, including metallurgical, chemical, oil refining, ceramic, paper, or other industries beyond that point having a direct bearing on the kind and source of discharge to the sewers or waterway or facilities for waste treatment.
While performing the necessary work on private properties referred to in § 245-37 above, the Superintendent or duly authorized employees of the City, the Illinois Environmental Protection Agency, and the United States Environmental Protection Agency 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 the City employees and liability claims and demands for personal injury or property damage asserted against the company and growing out of the gauging and sampling operations, except as such may be caused by negligence or failure of the company to maintain safe conditions as required in § 245-35.
The Superintendent and other duly authorized employees of the City bearing proper credentials and identification shall be permitted to enter all private properties through which the City holds a duly negotiated easement for the observation, measurements, sampling, repair, and maintenance of any portion of the sewage works lying within said easement.
