(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 of such size 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 and sand, mud, straw, shavings, metal, glass, rages, feathers, tar plastics, wood, unground garbage, punch manure, hair and fleshings, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
(E) Any pollutant, including oxygen-demanding pollutants (BOD, COD, etc.), release in a discharge of such volume or strength as to cause interference in the operation of the wastewater treatment plant.
(F) Heat in amounts which will inhibit biological activity in the waste water treatment plant resulting in interference, but in no case heat in such quantities that the temperature at the treatment plant influent exceeds forty (40) degrees Celsius (104 degrees F) unless the works can, in the judgment of the general manager, accommodate such heat.
