(A) Wastewater containing more than 50 milligrams per liter (mg/l) of petroleum oil, nonbiodegradable cutting oils, or products of mineral oil origin.
(B) Wastewater containing floatable oils, fat, or grease, whether emulsified or not, in excess of 100 milligrams per liter (mg/l) or containing substances which may solidify or become viscous at temperatures between 32°F (0°C) and 150°F (65°C).
(C) Any garbage that has not been properly shredded. Garbage grinders may be connected to sanitary sewers from homes, motels, institutions, restaurants, hospitals, catering establishments, or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers.
(D) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants which: injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, causes the city to violate the terms of its KPDES permit, prevents the use of acceptable sludge disposal methods, or exceed a limitation set forth in a Categorical Pretreatment Standard.
(E) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the city in compliance with applicable State or Federal Regulations.
(F) Any water or wastes which by interaction with other water or wastes in the public sewer system, release obnoxious gases, form suspended solids which interfere with the collection system, or create a condition deleterious to structures and treatment processes.
(G) Any wastewater with objectionable color which cannot be removed to an acceptable level within the operation of the wastewater treatment process but in no case, wastewater with a color that exceeds 100 ADMI units.
(H) Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed to the extent required by the city's NPDES/KPDES permit.
(I) Any waste(s) or wastewater(s) classified as a hazardous waste by the Resource Conservation and Recovery Act (RCRA) without a sixty (60) day prior notification of such discharge to the Superintendent. This notification must include the name of the hazardous waste, the EPA hazardous waste number, type of discharge, volume/mass or discharge and time of occurrence(s). The Superintendent may prohibit or condition the discharge(s) at any time.
(J) Any water or wastes which have characteristics based on a 24 hour composite sample, grab or a shorter period composite sample, if more representative, that exceed the following normal maximum domestic wastewater parameter concentrations:
Parameter Maximum Allowable Concentration Without Surcharges
Biochemical Oxygen Demand (BOD5) 325 mg/l
Total Suspended Solids (TSS) 325 mg/l
Ammonia-Nitrogen (NH3-N) 25 mg/l
Oil & Grease (total) 50 mg/l
Any person discharging wastewater exceeding the maximum allowable concentration as noted above, will be subject to a surcharge fee for each pound loading over and above the limit set above and an upper limit to be established when the Wastewater Discharge permit is issued. Any other amenable constituents requiring the addition of specific chemicals for proper treatment will also be subject to surcharge as noted on the Wastewater Discharge Permit. Exceedance of the effluent limits specified above shall not be deemed to constitute a violation of a permit condition or this chapter if the appropriated surcharge fee is paid and the discharge does not cause interference or pass through of the POTW.
(K) The following limitations are established for characteristics of any wastewaters to be discharged into the municipal sewer system. All significant industrial users must comply with these limitations where they are more stringent than applicable State and/or Federal Regulations.
Parameter Concentration (mg/l)
Arsenic TBE
Boron 1.00
Cadmium 0.01
Chromium (Hexavalent) 0.05
Copper 0.20
Cyanide, Total 0.10
Iron 5.00
Lead 0.10
Mercury TBE
Molybdenum TBE
Nickel 0.10
Potassium TBE
Selenium TBE
Silver TBE
Zinc 2.00
Total Toxic Organics TBE
Total Chromium TBE
(L) 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 procedures set forth in 40 CFR 136, and shall be determined at the control manhole provided or on suitable samples taken at said control manhole. In the event a control manhole has not 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 on the sewage system and to determine the existence of hazards of life, limb, and property.
