   (G)   Wastewater and its characteristics.
      BOD (denoting BIOCHEMICAL OXYGEN DEMAND). The quantity of oxygen utilized in the biochemical oxidation of organic matter under standards laboratory procedure in five days at 20°C, expressed in milligrams per liter.
      EFFLUENT CRITERIA. As defined in any applicable NPDES permit.
      FLOATABLE OIL. Oil, fat, or grease in a physical state such that it will separate by gravity from wastewater by treatment in an approved pretreatment facility. A wastewater shall be considered free of floatable fat if it is properly pretreated and the wastewater does not interfere with the collection system.
      GARBAGE. Solid wastes from the domestic and commercial preparation, cooking, and dispensing of food, and from the handling, storage and sale of food.
      INDUSTRIAL WASTE. Any solid, liquid or gaseous substance discharged, permitted to flow or escaping from any industrial, manufacturing, commercial or business establishment or process or from the development, recovery or processing of any natural resource as distinct from sanitary sewage.
      MAJOR CONTRIBUTING INDUSTRY. An industrial user of the publicly owned treatment works that:
         (a)   Has a flow of 50,000 gallons or more per average work day; or
         (b)   Has a flow greater than 10% of the flow carried by the municipal system receiving the waste; or
         (c)   Has in its waste, a toxic pollutant in toxic amounts as defined in standards issued under section 307(a) of the Federal Act; or
         (d)   Is found by the permit issuant authority, in connection with the issuance of the 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.
      MILLIGRAMS PER LITER. A unit of the concentration of water or wastewater constituent. It is 0.001 g of the constituent in 1,000 ml of water. It has replaced the unit formerly used commonly, parts per million, to which it is approximately equivalent, in reporting the results of water and wastewater analysis.

      SEWAGE is used interchangeably with WASTEWATER.

      SUSPENDED SOLIDS (SS). Solids that either float, on the surface of, or are in suspension in water, sewage, or industrial waste, and which are removable by a laboratory filtration device. Quantitative determination of SUSPENDED SOLIDS shall be made in accordance with procedures set forth in the IEPA Division of Laboratories Manual of Laboratory Methods.
      UNPOLLUTED WATER. Water 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 benefited by discharge to the sanitary sewers and wastewater treatment facilities provided.
      WASTEWATER. The spent water of a community. From this standpoint of course, 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 storm water that may be present.

   (H)   Sewer types, and appurtenances.
      BUILDING DRAIN That part of the lowest piping of a drainage system which receives the discharge from soil, waste, and other drainage pipes inside the walls of the building and conveys it to the building sewer or other approved point of discharge, beginning five feet (1.5 meters) outside the inner face of the building wall.
