Any wastewater containing toxic pollutants or prohibited substances or wastes, as defined herein, in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the Town sanitary sewer system or exceed the limitation set forth in a categorical pretreatment standard.

Any noxious or malodorous liquids, gases or solids which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewers, storm sewer or storm drain for maintenance and repair.

In no case shall a substance discharged to the publicly owned treatment works cause the publicly owned treatment works to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act, any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Water Act or the Toxic Substances Control Act or NYSDEC criteria applicable to the sludge management method being used.

Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations.

Any wastewater which causes a hazard to human life or creates a public nuisance.

Any wastewater containing fats, wax, grease or oils, whether emulsified or not, in excess of 100 mg/l of solvent-soluble materials or containing substances which may solidify or become viscous at temperatures below 65° C. (150° F.).

Any garbage that has not been properly shredded. The installation and operation of garbage grinders equipped with a motor of three-fourths (3/4) horsepower [seventy-six hundredths (.076) horsepower metric] or greater shall be subject to the review and approval of the Superintendent.

Any material which contains or causes:

(1)

Unusual concentrations of 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.

(2)

Excessive discoloration in the sewer system or at the publicly owned treatment works treatment plant, such as but not limited to dye solutions and vegetable tanning solutions.

(3)

Unusual BOD, COD or chlorine requirements in such quantities as to constitute a significant additional load on the publicly owned treatment works, except as provided for under Article VII.

Any wastewaters or waste materials containing more than two mg/l of the following gases: hydrogen sulfide, sulfur dioxide or nitrogen oxides.

Any wastewaters or waste materials from industrial processes or hospital procedures containing antibiotics or viable pathogenic organisms in sufficient concentrations or amounts to interfere with any wastewater treatment process, constitute a hazard to humans or animals or create a toxic effect in the receiving waters of the publicly owned treatment works.
