(A) General prohibitions. No industrial user shall introduce or cause to be introduced into the POTW any pollutant or wastewater which causes pass through or interference. These general prohibitions apply to all users of the POTW whether or not they are subject to categorical pretreatment standards or any other national, state or local pretreatment standards or requirement.
(B) Specific prohibitions.
(1) No user shall introduce or cause to be introduced into the POTW the following pollutants, substances or wastewater:
(a) Pollutants which create a fire or explosive hazard in the municipal wastewater collection and POTW, including, but not limited to, waste streams with a closed-cup flashpoint of less than 140°F (60°C) using the test methods specified in 40 C.F.R. § 261.21;
(b) Wastewater having a pH less than 5.0 or more than 11.0, or otherwise causing corrosive structural damage to the POTW or equipment;
(c) Solid or viscous substances in amounts which will cause obstruction of the flow in the POTW resulting in interference, but in no case solids greater than three inches or 7.6 centimeter(s) in any dimension;
(d) Pollutants, including oxygen demanding pollutants (BOD and the like), released in a discharge at a flow rate and/or pollutant concentration which, either singly or by interaction with other pollutants, will cause interference with either the POTW; or any wastewater treatment or sludge process, or which will constitute a hazard to humans or animals;
(e) Wastewater having a temperature greater than 104°F (40°C), 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 104°F (40°C);
(f) Petroleum oil, nonbiodegadable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through;
(g) Pollutants which result in the presence of toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems;
(h) Trucked or hauled pollutants, except at discharge points designated by the town in accordance with § 52.038;
(i) Noxious or malodrous liquids, gases, solids or other wastewater which, either singly or by interaction with other wastes, are sufficient to create a public nuisance, a hazard to life, or to prevent entry into the sewers for maintenance and repair;
(j) Wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the POTW effluent thereby violating the town’s VPDES permit;
(k) Wastewater containing any radioactive wastes or isotopes except in compliance with applicable state or federal regulations;
(1) Stormwater, surface water, groundwater, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, noncontact cooling water and unpolluted industrial wastewater, unless specifically authorized by the Wastewater Superintendent;
(m) Sludges, screenings or other residues from the pretreatment of industrial wastes;
(n) Medical wastes, except as specifically authorized by the Wastewater Superintendent in a wastewater discharge permit;
(o) Wastewater causing, alone or in conjunction with other sources, the treatment plant’s effluent to fail a toxicity test;
(p) Detergents, surface active agents or other substances which may cause excessive foaming in the POTW;
(q) Fats, oils or greases of animal or vegetable origin in concentrations greater than 500 mg/l; and
(r) Wastewater causing a reading on an explosion hazard meter at the point of discharge into the POTW, or any point in the POTW, over the lower explosive limit of the meter.
(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 POTW.
(3) All floor drains located in process or materials storage areas must discharge to the user’s pretreatment facility before connecting with the POTW.
(C) Requirements. This chapter references the significant industrial user’s wastewater discharge permit. The user shall be required to meet all requirements of the town wastewater discharge permit.
