(A) No user shall introduce or cause to be introduced into the wastewater system any pollutant or wastewater, which causes pass through or interference. These general prohibitions apply to all users of the wastewater system whether or not they are subject to categorical pretreatment standards or any other federal, state, or local pretreatment standards or requirements.
(B) (1) In connection with this code and except as provided in this chapter, no user or other person shall discharge or permit to be discharged any of the following described waters or wastes into the wastewater system:
(a) Wastewater having a temperature greater than 150° Fahrenheit, or which will inhibit biological activity in the treatment plant resulting in interference, but in no case wastewater which causes the temperature at the introduction into the treatment plant to exceed 120° Fahrenheit;
(b) Any water or waste which contains fats, oil, or grease in amounts that cause obstruction or interference of the wastewater treatment system, and at no time in amounts greater than 100 parts per million;
(c) Pollutants which create a fire or explosive hazard in the wastewater system, including but not limited to wastestreams with a closed-cup flashpoint of less than 140° Fahrenheit using the test methods specified in 40 CFR 261.21, and any gasoline, benzene, naphtha, fuel, or other flammable or explosive liquid, solid, or gas;
(d) Solid or viscous substances in amounts which will cause obstruction of the flow in the wastewater system resulting in obstruction or interference with the wastewater treatment system, but in no case solids greater than 1/2-inch in any dimension, any garbage that has not been properly shredded, or any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch manure, abrasives such as brick, cement onyx, or carbide;
(e) Any water or wastes having a pH lower than 6 or higher than 9-1/2, or having any other corrosive property capable of causing damage to the structures, equipment, and personnel of the wastewater system;
(f) Any water or wastes which contain or result in the presence of toxic, radioactive, or poisonous gases, vapors, or fumes within the wastewater system in a quantity that may injure or interfere with any wastewater treatment process, cause acute worker health and safety problems, or otherwise constitute a hazard to humans, or create any hazard in the utilization of the effluent of the wastewater system;
(g) Any waters or wastes containing dissolved or suspended solids of such character and quantity that unusual attention or expense is required to handle such materials in the wastewater treatment system;
(h) Noxious or malodorous liquids, gases, or solids or other wastewater which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or a hazard to life or to prevent entry into the sewers for maintenance or repair;
(i) Any pollutant, including oxygen-demanding pollutants (BOD and the like), released in a discharge at a flow rate and/or pollutant concentration which, singly or by interactions with other pollutants, will cause interference with the wastewater system;
(j) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through;
(k) Trucked or hauled pollutants, except at discharge points approved by the town;
(l) Any drainage waters, including but not limited to storm water, surface water, groundwater, roof runoff, cellar or other subsurface drainage, swimming pool drainage, condensate, or deionized water, without the express permission of the town;
(m) Any noncontact cooling or unpolluted process water, without the express permission of the town;
(n) Sludges, screenings, or other residues from the pretreatment of industrial wastes;
(o) Medical wastes, except as specifically authorized by the town in an industrial wastewater discharge permit; or
(p) Any material deposited into a manhole through its top, unless specifically authorized by the town.
(2) Pollutants, substances, or wastewater prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the wastewater system.
