<br />(b) Any waters or wastes containing toxic or poisonous solids,
<br />liquids, or gases in sufficient quantity, either singly or by interactio:
<br />with other wastes, to injure or interfere with any sewer treatment
<br />process, constitute a hazard to humans or animals, create a public
<br />nuisance, or create any hazard in the receiving waters of the sewage
<br />treatment plant, including but no limited to cyanides in excess of two
<br />(2) mg/l as CN in the wastes as discharged to the public sewer.
<br />(c) Any waters or wastes having a pH lower than 2,1i or having any
<br />other corrosive property capable of causing damage or hazard to structurE
<br />equipment, and personnel of the sewage works.
<br />(d) Solid or viscous substances in Santities or of such size capable
<br />of causing obstruction to the flow in sewers, or other interference
<br />with the proper operation of the sewage works such as, but not limited

<br />consideration to such factors as the quantities oZ subject wasts in
<br />relation'to flows and velocities in the sewers, materials of construction
<br />of the sewers, nature of the sewage treatment process, capacity of the
<br />sewage treatment plant, degree of treatability of wastes in the sewage
<br />treatment plant, and other pertinent factors. The +►substance pro-
