(1) “Administrative Director” means the Administrative Director, or his authorized deputy, agent, or representative.
(2) “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 three feet outside the inner face of the building wall.
(3) “Chemical Biological Oxygen Demand" (CBOD) means the quantity of oxygen utilized in the chemical biological oxidation of organic matter under standard laboratory procedures in five days at twenty degrees Centigrade, expressed in milligrams per liter.
(4) "Chemical Oxygen Demand" (COD) means the quantity of oxygen utilized in the chemical oxidation of organic matter under standard laboratory procedures expressed in milligrams per liter.
(5) "Compatible Pollutant" means CBOD, suspended solids, pH, and fecal coliform bacteria plus additional pollutants identified in the NPDES permit if the publicly owned treatment works was designed to treat such pollutant, and in fact does remove such pollutants to a substantial degree. Examples of such additional pollutants may include:
A. COD;
B. Total organic carbon;
C. Phosphorous and phosphorous compounds;
D. Nitrogen and nitrogen compounds;
E. Fats, oils and greases of animal or vegetable origin.
(6) “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.
(7) “Domestic sanitary wastewater” means a wastewater discharge having the average characteristics equivalent to 200 mg/l CBOD and 200 mg/l suspended solids concentration.
(8) “Garbage” means solid wastes from the preparation, cooking, and dispensing of food and from the handling, storage, and sale of produce.
(9) “Incompatible pollutant” means any pollutant which is not a compatible pollutant as defined above.
(10) “Industrial user” means any nongovernmental user of a publicly owned treatment works which discharges wastewater to the treatment works which contains toxic pollutants or poisonous solids, liquids, or gases in sufficient quantity either singly or by interaction with other wastes to contaminate the sludge of the municipal system, or to injure or to interfere with any sewage treatment process, or which constitutes a hazard to humans or animals, creates a public nuisance, or creates any hazard in or has an adverse effect on the waters receiving any discharge from the treatment works; or, any nongovernmental nonresidential user of a publicly owned treatment works which discharges more than the equivalent of 25,000 gallons per work day (GPD) of sanitary wastes and which is identified in the Standard Industrial Classification Manual, 1972, Office of Management and Budget, as amended and supplemented, under one of the following divisions:
Division A. Agriculture, Forestry, and Fishing
Division B. Mining
Division C. Manufacturing
Division D. Transportation, Communications, Electric, Gas, and Sanitary Services
Division I. Services
(11) “Industrial” includes manufacturing activities involving the mechanical or chemical transformation of materials or substances into other products. These activities occur in establishments usually described as plants, factories or mills and characteristically use power driven machines and material handling equipment.
A. In determining the amount of a user's discharge, the Municipality may exclude domestic waste discharges from sanitary conveniences.
B. After applying the sanitary waste exclusion in subsection (a)(11)A. hereof (if the Municipality chooses to do so), dischargers in the above divisions that have a volume exceeding 25,000 GPD or the weight of chemical biological oxygen demand (CBOD) or suspended solids (SS) equivalent to that weight found in 25,000 GPD of sanitary waste are considered industrial users. “Sanitary waste”, for the purposes of this calculation of equivalency, means CBOD5 less than or equal to 200 mg. per liter and suspended solids less than or equal to 200 mg. per liter.
(12) “Industrial wastes" means the wastewater from industrial processes, trade, or business as distinct from domestic sanitary wastes.
(13) “Major contributing industry” means an industrial user of the publicly owned treatment works that:
A. Has a flow of 50,000 gallons or more per work day;
B. Has a flow greater than five percent (5%) of the flow carried by the municipal system receiving the waste;
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 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.
(14) “Natural outlet” means any outlet into a watercourse, pond, ditch, lake, or other body of surface or ground water.
(15) “Person" means any individual, firm, company, association, society, corporation, or group.
(16) “pH” means the logarithm of the reciprocal of the weight of hydrogen ions in grams per liter of solution.
(17) “Pollutant" means dredged spoil, solid waste, incinerator residue, wastewater, garbage, wastewater sludge, munitions, wrecked or discarded equipment, rock, sand, cellar dirt, and industrial, municipal and agricultural waste discharged into the water.
(18) “Properly shredded garbage” means 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 in any dimension.
(19) “Public sewer” means a sewer controlled by the Municipality or other public authority.
(20) “Sanitary sewer” means a sewer which carries sewage and wastes and to which storm, surface, and ground waters are not intentionally admitted.
(21) “Sewage” means a combination of water-carried wastes from residences, business buildings, institutions, and industrial establishments.
(22) “Sewage treatment plant” means any arrangement of devices and structures used for treatment of sewage.
(23) “Sewer” means a pipe or conduit for carrying sewage.
(24) “Sewerage works” means all facilities for collecting, pumping, treating, and disposing of sewage.
(25) "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 (15) 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.
(26) “Storm sewer” or “storm drain” means a sewer which carries storm and surface waters and drainage, but excludes sewage and polluted industrial wastes.
(27) “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".
(28) “Toxic pollutants" include but not necessarily limited to aldrin-dieldrin, benzidine, cadmium, cyanide, 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.
(29) “Unpolluted water" means 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.
(30) “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 storm water that may be present.
(31) “Watercourse” means a channel in which a flow of water occurs, whether continuously or intermittently.
