   (4)   “Building drain” means that part of the lowest horizontal 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, beginning 5 feet outside the inner face of the building wall.

   (5)   “Building sewer” means the extension from the building drain to the POTW or other place of disposal.

   (6)   “Categorical Pretreatment Standards” means National Pretreatment Standards specifying quantities or concentrations of pollutants or pollutant properties which may be discharged or introduced into a POTW by specific industrial dischargers.

   (7)   “Dilution” means increased use of potable or process water or mixing of separate waste streams.

   (8)   “Industrial users” means any nonresidential user who discharges an effluent into a POTW 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.

   (9)   “Industrial waste” means solid, liquid, or gaseous waste resulting from any industrial, manufacturing, trade, or business process or from the development, recovery, or processing of natural resources.

   (13)   “pH” means the logarithm of the reciprocal of the hydrogen ion concentration.

   (14)   “Pollutant” means any element, substance, or material which, after addition to water, alters the physical, chemical or biological purity of that water.

   (15)   “POTW” means publicly owned treatment works and the sewage treatment works and the sewers and conveyance appurtenances discharging thereto, owned and operated by the Authority.

   (16)   “Pretreatment” means any physical, chemical, or biological process which reduces, alters, or eliminates the pollutant properties of a wastewater before it is discharged to the POTW.

   (17)   “Properly shredded garbage” means the wastes from the preparation, cooking, and dispensing of food that have been shredded to such degree that all particles will be carried freely under the flow conditions normally prevailing in public sewers, with no particle greater than 1/2 inch in any dimension.

   (18)   “Residual” means any material--liquid, sludge, slurry, ash, and solid--which must be disposed of after use in or removal from an industrial activity, including pretreatment, but not discharged to the POTW. Residuals shall not include noncontact cooling waters.

   (19)   “Sanitary sewer” means a conduit which carried wastewater to a wastewater treatment facility and in which storm, surface, and groundwaters are not intentionally admitted.

   (20)   “Sewer” means any pipe, conduit, ditch, or other device used to collect and transport sewage or storm water from the generating source.

   (21)   “Sewage” means the same as wastewater--the spent water of a community. “Sewage” may be a combination of 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.

   (22)   “Sewage treatment works” means the same as wastewater treatment plant: an arrangement of devices and structures for treating wastewater and sludge.

   (23)   “Shall” means "is mandatory."

   (24)   “Slug load” means any pollutant, including oxygen demanding pollutants, released in a discharge at an extraordinary rate and/or concentration which causes interference to the POTW.

   (25)   “Storm sewer” means a conduit which carries rainfall, surface waters and drainage, or other unpolluted waters and does not enter the POTW.

   (26)   “Suspended solids” means solids that float on the surface of or are in suspension in water, wastewater, or other liquids and are quantified by laboratory procedures set forth in "Standard Methods for the Examination of Water and Wastewater."

   (27)   “Toxic pollutant” means any substance or combination of substances, including disease-causing agents, which after discharge and upon exposure, ingestion, inhalation, or assimilation into any organism, either directly from the environment or indirectly by ingestion through food chains, will, on the basis of information available to the City Manager, cause death, disease, behavioral abnormalities, cancer, genetic mutation, physiological malfunctions (including malfunctions in reproduction), or physical deformation in such organisms or their offspring. These substances include, but are not limited to those listed in Appendix A attached to original Ordinance 85-33.

   (28)   “Upset” means serious failure in any part of the POTW that can be attributed to the nature or quantity of wastewater discharged to the POTW.

   (29)   “User” means any person, residence, or establishment that discharges an effluent to the POTW.
