No person shall introduce or cause to be introduced, directly or indirectly, into the POTW the following pollutants, substances, or wastewater.
(A) A pollutant which by reason of its nature or quantity is, or may be, sufficient either alone or by interaction with other substances to create a fire or explosion hazard in the POTW, including, but not limited to, wastestreams with a closed cup flashpoint of less than 140° Fahrenheit or 60° Centigrade using the test methods specified in 40 CFR § 261.21. In addition, at no time shall 2 successive readings on an explosion hazard meter, at the point of discharge into the system, or at any point in the system, be more than five percent or any single reading exceed 10% of the lower explosive limit (LEL) of the substance measured, Such pollutants may include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides.
(B) A solid or viscous pollutant, or other substances, which may cause obstruction to the flow in a sewer or other interference with the operation of the POTW such as, but not limited to:
(1) Grease, garbage with particles greater than ½ inch in any dimension, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, 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, plastics, gasoline, tar, asphalt residues, residues from refining, or processing of fuel or lubricating oil, mud, or glass grinding or polishing wastes;
(2) Petroleum oil, non-biodegradable cutting oil or products of mineral oil origin in amounts that may cause interference or pass through;
(3) Any pollutant having a pH greater than 10.0 S.U. more than 1% of the time each month or for a period exceeding 30 minutes; or any pollutant having any corrosive property capable of causing damage or hazard to structures, equipment, or personnel of the POTW; or, in no case, any discharges with pH lower than 5.0 S.U. The POTW may require continuous documentation of compliance through pH strip chart recordings;
(4) Any pollutant which would either singly or by interaction with other pollutants result in the presence of noxious or toxic gases, vapors, or fumes within the POTW in a quantity sufficient to create a public nuisance or hazard to human health or to prevent entry into the sewers for maintenance, repairs, inspections, or monitoring;
(5) Any pollutant, which may cause the POTW's effluent or any other product of the POTW such as residues, sludge, or scum to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case, shall a pollutant discharged to the POTW cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations of the Act; any criteria, guidelines, or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substance Control Act, or state criteria applicable to the sludge management method being used;
(6) Any pollutant which may cause the POTW to violate its NPDES Permit;
(7) Any wastewater with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions;
(8) Any wastewater having a temperature which will inhibit biological activity in the POTW resulting in interference or damage to the POTW, but in no case wastewater causing the temperature at the introduction into the POTW to exceed 40°C (104°F);
(9) Any pollutant, including an oxygen demanding pollutant such as, but not limited to, cBOD5 or COD, released at a flow rate which will, either singly or by interaction with other pollutants, cause interference with the POTW. In no case, shall a slug discharge have a flow rate for any time period longer than 15 minutes, that is more than 5 times the flow during normal operation;
(10) Any pollutant, including an oxygen demanding pollutant such as, but not limited to, cBOD5 or COD, released at a pollutant concentration or contain concentrations or quantities of pollutants which will, either singly or by interaction with other pollutants, cause interference with the POTW. In no case, shall a slug discharge have pollutant concentration or contain concentrations or quantities of pollutants that exceed the average 24-hour concentration or quantities during normal operation;
(11) Any pollutant containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established under applicable state or federal regulations;
(12) Any pollutant, which either alone or by interaction with other pollutants, causes a hazard to human health, creates a public nuisance, or is detrimental to the POTW;
(13) Storm water, surface water, groundwater, artisan well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, and non-contact cooling water, unless specifically authorized by the Director;
(14) Sludges, screenings, or other residues from the pretreatment of industrial wastes;
(15) Medical wastes, except as specifically authorized by the Director in an industrial wastewater discharge permit;
(16) Detergents, surface-active agents, or other substances which may cause excessive foaming in the POTW;
(17) Trucked or hauled pollutants, except as allowed by the Director under special circumstances; and
(18) Any wastewater that causes the average concentration of hydrogen sulfide (H2S) gas in the POTW to exceed 5 ppm or the maximum concentration of 50 ppm at any time.
(C) No healthcare facility or reverse distributor as defined in 40 CFR Part 266 Subpart P shall discharge to the POTW any hazardous waste pharmaceutical as defined in 40 CFR Part 266 Subpart P.
