(23) “Suspended solids” means total suspended matter that either floats on the surface of, or is in suspension in, water, wastewater or other liquids, and that is removable by laboratory filtering as prescribed in “Standard Methods for the Examination of Water and Wastewater” and referred to as nonfilterable residue.
(24) “Toxic pollutants” includes but is not necessarily limited to aldrin-dieldrin, benzidine, cadmium, cyanide, DDT-endrin, mercury, polychlorinated byphenyls (PCB’s) and toxaphene. Pollutants included as “toxic” shall be those promulgated as such by USEPA.
(25) “Unpolluted water” means water of quality equal to or better than the effluent criteria in effect or water that would not cause violation of receiving water quality standards and would not be benefitted by discharge to the Municipal wastes works.
(26) “Upset” means an exceptional incident in which a User unintentionally and temporarily is in a state of noncompliance with the standards set forth in this chapter due to factors beyond the reasonable control of the User and excluding noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation thereof.
(27) “USEPA” means the United States Environmental Protection Agency.
(28) “User” means any person who discharges an effluent into the Municipal Wastes Works by means of pipes, conduits, pumping stations, force mains, constructed drainage ditches, surface water intercepting ditches, intercepting ditches, and all constructed devices and appliances appurtenant thereto. The divisions of users within the Village’s services area is by the origin of the sewage discharged and by the similarity of the function of such users. Stated in four general classes, they are:
A. “Commercial user” means a commercial business discharging wastewater; users not categorized as residential or industrial.
B. “Industrial user” means a person who discharges into the Village’s sewage treatment system liquid wastes resulting from processes employed in industrial or manufacturing, or from the development of any natural resource.

On the pH scale (0-14), a value of 7 at 25' C (77'F) represents a neutral condition. Decreasing values indicate increasing hydrogen-ion concentrations (acidity); increasing values indicate decreasing hydrogen-ion concentration (alkalinity).
