(A) General prohibition. A user may not introduce into the collection system of the city or the POTW any pollutant which causes pass through or interference.
(B) Prohibited waste discharges. Except as hereinafter provided, it shall be unlawful for any person to discharge or cause to be discharged into the collection system of the city or a community service area, or any opening, sump, tank, clarifier, piping or waste treatment system which drains or flows into the collection system of the city or a community service area, any of the following:
(1) Any earth, sand, rocks, ashes, gravel, plaster, concrete, glass, metal filings or metal or plastic objects, garbage or solid, semi-solid or viscous material in quantities or volume which will obstruct the flow of sewage in the collection system, or any object which will cause clogging of a sewer or sewage sludge pump or interferes with the normal operation of the city's POTW;
(2) Any compound which will produce noxious odors or toxic gases, vapors or fumes in the city's POTW;
(3) Recognizable portions of human or animal anatomy;
(4) Any solids, liquids, gases, devices or explosives which, by themselves or by interaction with other substances or sewage, may cause fire or explosion hazards, exceed 10% of the lower explosive limit at the point of discharge or in the collection system, or in any other way create imminent danger to wastewater personnel, the environment or public health;
(5) Any wastewater or material with a closed cup flash point of less than 140°F or 60°C, using the test methods specified in 40 CFR 261.21;
(6) Any overflow from any septic tank, cesspool, seepage pit or any liquid or sludge pumped from a cesspool, septic tank or seepage pit, except as may be permitted by the Director;
(7) Any discharge from the wastewater holding tanks of recreational vehicles, trailers, buses and other similar vehicles, except as may be permitted by the Director;
(8) Any storm water, groundwater, street drainage, subsurface drainage, yard drainage or any runoff from any field, roof, yard, driveway or street. The Director may approve, on a temporary basis, the discharge of such water only when no reasonable alternative method of discharge is available;
(9) Any substance or heat in amounts which will inhibit biological activity in the city's POTW resulting in interference, or which will cause the temperature of the sewage in any public sewer to be higher than 140°F. In no case shall any substance or heat be discharged to the sewer which will raise the POTW effluent higher than 104°F (40°C);
(10) Any radioactive waste in excess of federal, state or county regulations;
(11) Any material or quantity of material which will:
(a) Cause damage to any part of the collection system;
(b) Cause abnormal maintenance of the collection system;
(c) Cause an increase in the operational costs of the collection system;
(d) Become a nuisance or menace to public health;
(e) Cause interference or pass through in the city's POTW, its treatment processes, operations, sludge processes, use or disposal;
(f) Cause a violation of the city's state or future NPDES permits; CSDOC's existing NPDES permit, in the event the wastewater is discharged to the Inland Empire Brine Line; or WRCRWA's NPDES permit in the event the wastewater is discharged to the WRCRWA plant;
(12) Any quantities of herbicides, algaecides or pesticides;
(13) Any petroleum oil, non-biodegradable cutting oil or products of mineral oil origin;
(14) Any material or quantity of material(s) which will cause abnormal sulfide generation;
(15) Any water or wastewater used to artificially raise the industrial user's discharge rate or added for the purpose of diluting wastes which would otherwise exceed applicable permitted discharge limitations;
(16) Any wastewater having a corrosive property capable of causing damage to the city's collection system, POTW, equipment or structures or presenting a hazard to city personnel. However, in no case shall wastewater be discharged to the city's collection system or POTW with a pH below 5.0 or greater than 10.5, or that will change the effluent of the city's POTW to above 8.0 or below 6.5;
(17) Any substance which will cause discoloration of the city's POTW effluent;
(18) Any unpolluted water that violates any city- or state-adopted water conversation programs or policies; constitutes a dilution stream for the purposes of meeting concentration limits as an alternative to treatment; or that has the potential to cause or contribute to surcharged conditions in the sewer collection or treatment system. Sources of unpolluted water include, but are not limited to, cooling water, heating water, storm water, subsurface water and single-pass cooling water. The Director may approve, on a temporary basis, the discharge of such water only when no reasonable alternative method of discharge is available. The user shall pay all applicable user charges and fees;
(19) Any substance which may cause the city's POTW effluent or any other product such as residues, sludges or scums to be unsuitable for reclamation or reuse, or which will interfere with the reclamation process. This includes any material which will cause the sludge at the city's POTW to violate applicable sludge use or disposal regulations developed under the Act, 33 USCA 1251 et seq., or any regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, 12 USCA 6901 et seq.; Clean Air Act, 12 USCA 7401 et seq.; Toxic Substance Control Act, 16 USCA 2601 et seq.; or state regulations;
(20) Any hazardous substance which violates the objectives of the general pretreatment regulations, this chapter or any statute, rule, regulation or chapter of any public agency having jurisdiction over the discharge;
(21) Any toxic material in excess of the quantities established by resolution or ordinance adopted by the City Council. The maximum quantity of toxic material permitted to be released into the city's collection system shall be approved by the City Council, and may thereafter be amended from time to time by resolution or ordinance as necessary to comply with state and federal pretreatment standards and local discharge limits;
(22) Any pollutant, including oxygen-demanding pollutants (BOD), released in a discharge at a flow rate and/or pollutant concentration which will cause interference with the city's POTW;
(23) Any pollutants in concentrations exceeding the maximum levels established by resolution or ordinance of the City Council. The maximum concentration levels of pollutants permitted to be released into the city's collection system shall be approved by the City Council and adopted by resolution, and may thereafter be amended from time to time to comply with state and federal pretreatment standards and local discharge limits as the City Council deems is reasonable and necessary;
(24) Any wastewater subject to regulations, except pursuant to valid permit from the city.
