(l) "Floatable oil" is oil, fat or grease in a physical state such that it will separate by gravity from wastewater by treatment in an approved pretreatment facility.
(m) "Garbage" means the animal and vegetable waste resulting from the handling, preparation, cooking and serving of food.
(n) "Incompatible pollutant" means any pollutant which is not a compatible pollutant as defined in subsection (f).
(o) "Industrial wastes" means the wastewater from industrial processes, trade, or business as distinct from domestic or sanitary wastes.
(p) "Major contributing industry" means an industrial user of the publicly owned treatment works that:
(1) Has a flow of 50,000 gallons or more than average work day;
(2) Has a flow greater than five percent (5%) of the flow carried by the Municipal system receiving the waste;
(3) Has in its waste a toxic pollutant in toxic amounts as defined in standards issued under Section 307(a) of the Federal Act; or
(4) Is found by the permit issuance authority in connection with the issuance of an NPDES permit to the publicly owned treatment works receiving the waste, to have significant impact, either singly or in combination with other contributing industries, on that treatment works or upon the quality of effluent from that treatment works.
(q) "May" is permissive; "shall" is mandatory.
(r) "Natural outlet" means any outlet, including storm sewers and combined sewer overflows, into a watercourse, pond, ditch, lake, or other body of surface or ground water.
(s) "NPDES" permit means the National Pollutant Discharge Elimination System permit.
(t) "Person" means any individual, firm, company, association, society, corporation, or group.
(u) "pH" means the reciprocal of the logarithm of the hydrogen ion concentration. The concentration is the weight of hydrogen ions, in grams, per liter of solution. Neutral water, for example, has a pH value of 7 and a hydrogen ion concentration of 10-7.
(v) "Pollutant" means dredged spoil, solid waste, incinerator residue, wastewater, garbage, waste water sludge, munition, wrecked or discarded equipment, rock, sand, cellar dirt, and industrial, municipal and agricultural waste discharged into the water.
(w) "Properly shredded garbage" means the waste from the preparation, cooking and dispensing of food that have been shredded to such a degree that all particles will be carried freely under the flow conditions normally prevailing in public sewers, with no particle greater than one-half inch (.127 centimeters) in any dimension.
(x) "Pretreatment" means the treatment of wastewaters from sources before introduction into publicly owned wastewater treatment facilities.
(y) "Public sewer" means a common sewer controlled by a government agency or public utility.
(z) "Sanitary sewer" means any part of a sewer system that carries liquid and water-carried wastes from residences, commercial buildings, industrial plants, and institutions, together with minor quantities of ground, storm and surface waters that are not admitted intentionally.
(aa) "Slug" means any discharge of water or wastewater which in concentration of any given constituent or in quantity of flow exceeds for any period of duration longer than fifteen minutes more than five times the average twenty-four hour concentration or flows during normal operation and shall adversely affect the collection system and/or performance of the wastewater treatment works.
(bb) "Storm drain" (sometimes termed "storm sewer") means a drain or sewer for conveying water, ground-water, subsurface water, or unpolluted water from any source.
(cc) "Superintendent" means the Water Pollution Control Operator of the Village or his authorized representative.
(dd) "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 non-filterable residue.
(ee) "Cooling water" means the water discharged from any use such as air conditioning, cooling or refrigeration, during which the only pollutant added to the water is heat.
(ff) "Toxic pollutants" include but are not necessarily limited to aldrin-dieldrin, benzidine, cadmium, cynanide, DDT-endrin, mercury, polychlorinated biphenyls (PCB's) and toxaphene. Pollutants included as "toxic" shall be those promulgated as such by the United States Environmental Protection Agency.
(gg) "Unpolluted water" is 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 sanitary sewers and wastewater treatment facilities provided.
(hh) "Wastewater" (Sanitary water) means the spent water of a community. From the standpoint of source, it may be a combination of the liquid and water-carried wastes from residences, commercial buildings, industrial plants and institutions, together with any groundwater, surface water, and stormwater that may be present.

(kk) "Storm water" means any flow occurring during or immediately following any form of natural precipitation and resulting therefrom. Water originating from precipitation which is captured in roof drains and down spouts, footer and foundation tiles, ground drainage tiles and catch basins and which does no undergo any use or contamination prior to disposal.
