(F) Clarification of word usage. SHALL is mandatory; MAY is permissible.
(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.
pH. The logarithm (base 10) of the reciprocal of the hydrogen-ion concentration expressed by one of the procedures, outlined in the IEPA Division of Laboratories Manual of Laboratory Methods.
POPULATION EQUIVALENT. A term used to evaluate the impact of industrial or other waste on a treatment works or stream. One POPULATION EQUIVALENT is 100 gallons of sewage per day, containing 0.17 pounds of BOD and 0.22 pounds of suspended solids.
PPM. Parts per million by weight.
PROPERLY SHREDDED GARBAGE. The wastes 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 (1.27 centimeters) in any dimension.
SEWAGE is used interchangeably with WASTEWATER.
SLUG. Any discharge of water, sewage or industrial waste which in concentration of any given constituent or in quantity of flow exceeds for any period of duration longer than 15 minutes more than five times the average 24-hour concentration or flows during normal operation.
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.
WATER QUALITY STANDARDS. As defined in the Water Pollution Regulations of Illinois.
(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.
EASEMENT. An acquired legal right for the specific use of land owned by others.
SEWER. A pipe or conduit for conveying sewage or any other waste liquids, including storm, surface and groundwater drainage.
BUILDING SEWER. The extension from the building drain to the public sewer or other place of disposal.
COMBINED SEWER. A sewer which is designed and intended to receive wastewater, storm, surface and groundwater drainage.
PUBLIC SEWER. A sewer provided by or subject to the jurisdiction of the city. It shall also include, sewers within or outside the boundaries of the city that serve one or more persons and ultimately discharge into the city sanitary (or combined) sewer system, even though those sewers may not have been constructed with city funds.
SANITARY SEWER. A sewer that conveys sewage or industrial wastes or a combination of both, and into which storm, surface, and groundwaters or polluted industrial wastes are not intentionally admitted.
STORM SEWER. A sewer that carries storm, surface and groundwater drainage but excludes sewage and industrial wastes other than unpolluted cooling water.
SEWERAGE. The system of sewers and appurtenances for the collection, transportation and pumping of sewage.
STORMWATER RUNOFF. That portion of the precipitation that is drained into the sewers.
(I) Treatment.
PRETREATMENT. The treatment of wastewaters from sources before introduction into the wastewater treatment works.
WASTEWATER TREATMENT WORKS. An arrangement of devices and structures for treating wastewater, industrial wastes, and sludge. Sometimes used as synonymous with WASTE TREATMENT PLANT or WASTEWATER TREATMENT PLANT or POLLUTION CONTROL PLANT.
(J) WASTEWATER FACILITIES. The structures, equipment, and processes required to collect, carry away, and treat domestic and industrial wastes and transport effluent to a watercourse.
(K) Watercourse and connections.
