A. 
Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
B. 
Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the sewage treatment plant, including but not limited to cyanide in excess of two milligrams per liter as CN in the wastes as discharged to the public sewer.
C. 
Any waters or wastes having a pH lower than 5.5 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works.
D. 
Solid or viscous substances in quantities or sizes capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewage works, such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails, and paper dishes, cups and milk containers, either whole or ground by garbage grinders.
No person shall discharge or cause to be discharged into the sewer system the following described substances, materials, waters or wastes:
A. 
Any liquid or vapor having a temperature higher than 150° F.
B. 
Any water or waste containing fats, wax, grease, or oils, whether emulsified or not, in excess of 100 milligrams per liter or containing substances which may solidify or become viscous at temperatures between 32° F. and 150° F.
C. 
Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of 3/4 horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Town.
D. 
Any waters or wastes containing strong acid iron pickling wastes or concentrated plating solution, whether neutralized or not.
E. 
Any waters or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances, or wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sewage at the sewage treatment works would exceed the limits established for such materials by the operator of the sewage treatment works.
F. 
Any waters or wastes containing phenols or other taste- or odor-producing substances in such concentrations exceeding limits which may be established by the operator of the sewage treatment works as necessary for treatment of the composite sewage, to meet the requirements of the state, federal or other public agencies of jurisdiction for such discharge to the receiving water.
G. 
Any radioactive waste or isotopes of such half-life or concentration as may exceed limits established by the operator of the sewage treatment works in compliance with applicable state or federal regulations.
H. 
Any waters or wastes having a pH in excess of 9.0.
I. 
Materials which could exert or cause:
(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 (such as, but not limited to, dye waste and vegetable tanning solutions).
(3) 
Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works as determined by the operator of the sewage treatment works.
(4) 
Unusual volume of flow or concentration of wastes constituting "slugs" as defined herein.
J. 
Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
It shall be unlawful for any person or persons to throw, discharge, put or place excrement, night soil or any other offensive deleterious matter into or along any waterways or banks thereof within the corporate limits of the Town or to throw, discharge, put or place the same into or along any gutter, drain or waterway flowing into said Town.
