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, including but not limited to cyanides in excess of one milligram per liter as CN in the wastes as discharged to the public sewer.[2]

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 Mayor and Council, that such wastes can harm either the sewers or 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 its opinion as to the acceptability of these wastes, the Mayor and Council 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 other pertinent factors.

J. 
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 other agencies having jurisdiction over the discharge to the receiving waters.
A. 
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 § 173-4 of this article and which in the judgment of the Mayor and Council 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 Mayor and Council 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 existing taxes or sewer charges, under provisions of § 173-10 of this article.
B. 
If the Mayor and Council permits the pretreatment or equalization of waste flows, the design or installation of the plants and equipment shall be subject to the review and approval of the Mayor and Council and subject to the requirements of all applicable codes, ordinances and laws.
Grease, oil and sand interceptors shall be provided when, in the opinion of the Mayor and Council, 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 Mayor and Council and shall be located so as to be readily and easily accessible for cleaning and inspection.
Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.
A. 
When required by the Mayor and Council, the owner of any property serviced by a 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 Mayor and Council. 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.
B. 
The Mayor and Council may require a user of sewer services to provide information needed to determine compliance with this chapter. The Mayor and Council may review and copy records to obtain the required information. These requirements may include:[1]
(1) 
Wastewater discharge peak rate and volume over a specified period.
(2) 
Information on raw materials, processes and products affecting wastewater volume and quality.
(3) 
Chemical analysis of wastewaters.
(4) 
A plot plan of sewers at the user's property showing sewer and pretreatment facility locations.
(5) 
Quantity and disposition of specific liquid sludge, oil, solvent or other material important to sewer use control.
(6) 
Details of wastewater pretreatment facilities.
(7) 
Details of systems to prevent and control the losses of materials through spills to the municipal sewers.
(8) 
Any other information required by the flow measurement, sampling, analysis and monitoring standards as adopted by the Mayor and Council.

Editor's Note: Added at time of adoption of Code (see Ch. 1, General Provisions, Art. I).
A. 
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this article shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater and shall be determined by or under the direct supervision of a qualified analyst at the control structure provided and upon suitable samples taken at said control structure. In the event that no special structure has been required, the control structure shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling methods, locations, times, durations and frequencies are to be determined on an individual basis by the Director of Public Works.
B. 
The user must collect wastewater samples using flow-proportional composite sampling techniques. In the event that flow-proportional sampling is infeasible, the Director may authorize the use of time-proportional sampling or at a minimum of four grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged. In addition, grab samples may be required to show compliance with instantaneous discharge limits.
C. 
Samples for oil and grease, temperature, pH, cyanide, phenols, sulfides and volatile organic compounds must be obtained using grab collection techniques.
