COMPATIBLE POLLUTANTS. Wastewater having or containing:
(a) Measurable biochemical oxygen demand;
(b) Suspended solids;

INDUSTRIAL WASTES. Any solid, liquid, or gaseous substance or form of energy discharged, permitted to flow into or enter the sewage system or ground from an industrial, manufacturing, commercial, or business process or from the development, recovery, or processing of any natural resource carried on by any person and shall further mean any waste from an industrial user, but not including sanitary sewage or storm water.
INFILTRATION. The water entering the sewerage system directly or via private sewers, building drains, and building sewers connected therewith, from the ground, through such means as, but not limited to, defective pipe joints, connections, or manhole walls.
INSPECTOR. The person authorized by the Council or the Superintendent to perform inspection duties assigned to him or her by the Council or Superintendent.
LATERAL SEWER. The extension from the building drain to the sewage system or other place of disposal.
MAJOR CONTRIBUTOR. A user discharging or introducing into the sewage system:
(a) A flow of more than 50,000 gallons per average workday;
(b) A toxic pollutant in toxic amounts as defined in paragraph 307 of Pub. Law No. 92-500, as amended;
(c) A flow or pollutant concentration as defined or identified as a problem pollutant or flow by applicable state or federal regulations or by the Council;
(d) An effluent of significant impact, either singly or in combination with other contributors, on the wastewater treatment plant or the quality of its effluent; or
(e) Any substance unusual or unique in quality or quantity requiring special attention or processing in order to effect proper wastewater treatment.
NORMAL DOMESTIC SEWAGE. Sewage discharged by residential users.
NPDES PERMIT. The National Pollutant Discharge Elimination System permit now or hereafter held by the city and setting forth conditions for the discharge of any pollutants or combination of pollutants.
NUISANCE. Any substance which is injurious to health or offensive to the senses or an obstruction to the free use of property so as to interfere with the comfort or enjoyment of life or property.
OPERATION AND MAINTENANCE. All expenses related directly to the operating and maintaining, including replacement of the sewage works as identified in the “Uniform System Accounts for Wastewater Utilities” or as prescribed by the State Board of Accounts under the general headings “Plant Operation and Maintenance,” “Sewer Operation and Maintenance,” “Customer Accounts,” “Administrative and General,” “Insurance,” and “Taxes.”
pH. The conventional scientific measure of the degree of acidity or alkalinity.
POLLUTION. An alteration of the quality of water by waste, contaminants, or pollutants to a degree which renders such water unfit for beneficial uses.
