(A) It is unlawful for any person not expressly authorized by the city to tap a sewerage collection main.
(B) It is unlawful for any person to directly or indirectly discharge, place or cause to be discharged any of the following described substances into the city's wastewater treatment system or any public sewer:
(1) Any liquids, solids or gases which, by reason of their nature or quantity are, or may be, sufficient either alone or by interaction with other substances to cause fire or explosion or be injurious in any other way to the wastewater treatment system or to the operation of the system. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toulon, xylene, ethers, alcohol, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides, sulfides and any wastes with a closed cup flash point of less than 140 degrees Fahrenheit (60 degrees Celsius).
(2) Solid or viscous substances which will or may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater treatment facilities such as, but not limited to, grease, garbage with particles greater than 1/2 inch in any dimension, animal guts or tissues, paunch manure, bones, hair, hides, or fleshing, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, wood, plastic, gas tar, asphalt, residues, residues from refining or processing of fuel or lubricating oil, mud or glass grinding or polishing wastes.
(3) Any wastewater having a pH less than 6.0 or more than 10.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the wastewater treatment system.
(4) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to inhibit or disrupt any wastewater treatment process, constitute a hazard to humans or animals, or create a toxic effect in the receiving waters of the wastewater treatment system. A toxic pollutant shall include but not be limited to any pollutant identified pursuant to Section 307(a) of the Act.
(5) Any noxious or malodorous liquids, gases, or solids which, either singly or by interaction with other wastes, are capable of creating a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for their maintenance and repair.
(6) Any wastewater with objectionable color not removed in the treatment process, such as, but not limited to dye wastes and vegetable tanning solutions.
(7) Any wastewater which creates conditions at or near the wastewater treatment system which violate any statute or any rule, regulation or ordinance of any public agency or state or federal regulatory body.
(8) Any wastewater from a facility in existence prior to December 4, 1995, containing a CBOD in excess of 260 mg/l and TSS in excess of 280 mg/l unless such discharge is allowed by a permit and written agreement between the city and discharger. Any facility with an initial discharge date of December 4, 1995, or later must meet the CBOD limit of 260 mg/l and the TSS limit of 280 mg/l.
(9) Any wastewater containing total phosphorus in excess of 1 kg/day unless such discharge is allowed by a permit and written agreement between the city and discharger.
(10) Any wastewater having a temperature greater than 150 degrees Fahrenheit (65.6 degrees Centigrade), or causing, individually or in combination with other wastewater, the influent at the wastewater treatment plant to have a temperature exceeding 104 degrees Fahrenheit (40 degrees Centigrade) or having heat in amounts which will inhibit biological activity in the wastewater facility resulting in interference.
(11) Any slug load, which shall mean any pollutant, including oxygen demand pollutants (CBOD, COD, TKN, TP, etc.), released in a discharge of such volume or strength as to cause inhibition or disruption in the wastewater treatment system.
(12) Non-contact cooling water or unpolluted storm or groundwater.
(13) Any wastewater containing fats, wax, grease, or oils, whether emulsified or not, in excess of 50 mg/l or containing substances which may solidify or become viscous at temperatures between 32 degrees Fahrenheit and 150 degrees Fahrenheit (0 degrees Centigrade and 65.6 degrees Centigrade); and any wastewater containing oil and grease concentrations of mineral or animal origin of greater than 50 mg/l whether or not emulsified.
(14) Wastewater containing 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) in such quantities that they would cause disruption with the wastewater treatment system.
(15) Radioactive wastes or isotopes of such a half-life or concentration that they are in noncompliance with standards issued by the appropriate authority having control over their use and which will or are likely to cause damage or hazards to the city's wastewater treatment system or personnel operating it.
(16) Wastewater containing the following substances in excess of the limits shown herein:
Toxic Pollutant | Discharge Limitation |
Cadmium (Cd) | 1.03 mg/l |
Chromium total (Cr) | 5.23 mg/l |
Copper (Cu) | 2.86 mg/l |
Cyanide (Cn) | 1.09 mg/l |
Lead (Pb) | 1.05 mg/l |
Mercury (Hg) | 0.01 mg/l |
Toxic Pollutant | Discharge Limitation |
Molybdenum (Mo) | 0.10 mg/l |
Nickel (Ni) | 3.65 mg/l |
Silver (Ag) | 2.14 mg/l |
Zinc (Zn) | 8.10 mg/l |
(17) Loadings in excess of those prescribed in § 52.64 (B)(16) may be accepted into the wastewater treatment facility pursuant to a written agreement between the discharger and the city, which agreement shall provide that:
(a) The discharger will pay all costs incurred by the city arising out of the discharge including fines and penalties;
(b) Discharge shall in no event exceed functional capacity of the city's treatment facility;
(c) Provision be made for constant monitoring of discharge as may be necessary;
(d) There exists the capability of shutting the discharge off before it enters the wastewater treatment system;
(e) The permit may be revoked or modified where necessary as the needs of the wastewater treatment facility dictate in connection with the demands placed on the facility, its capabilities and emergencies affecting its operation in compliance with the applicable requirements for its operation by the city;
(f) The discharger shall hold the city harmless for such discharge;
(g) Such other terms may be deemed appropriate to ensure the safe and verifiable granting of permission to place such excess loadings in the system. No permit shall be granted hereunder where such discharge would violate applicable federal or state laws or regulations or adversely impact upon the city's ability to comply with applicable terms of its NPDES permit or applicable regulations governing its wastewater treatment facility.
