In the interpretation of this chapter, the following definitions shall apply, unless the context clearly indicates otherwise:
(1) "Act." The Federal Water Pollution Control Act and the Clean Water Act are used interchangeably in this chapter and refer to Public Law 92-500, as adopted in 1972 and amended by Public Law 95-217 in 1977, and any succeeding amendments.
(2) "Authority" shall mean the State or Local governmental entity enacting and enforcing this chapter.
(3) "BOD" (Biochemical Oxygen Demand) shall mean the quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedures in five days at 20 degrees Centigrade, expressed in parts per million by weight.
(4) "Building Drain" shall mean 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 such discharge to the building sewer, beginning five feet outside the inner face of the building wall.
(5) "Building Sewer" shall mean the extension from the building drain to the public sewer or other place of disposal.
(6) "Categorical Pretreatment Standards" shall mean 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) "City" shall mean the City of Reed City, Michigan, and/or the duly authorized deputy, agent or representative.
(8) "COD"(Chemical Oxygen Demand) shall mean the oxygen consuming capacity of inorganic and organic matter present in wastewater.
(9) "Combined Sewer" or combination sewer shall mean a sewer receiving both surface runoff and sewage.
(10) "Combined Wastestream" shall mean the wastestream at industrial facilities where regulated process effluent is mixed with other wastewater, either regulated or unregulated prior to treatment.
(11) "Compatible Pollutant" shall mean the pollutants which are treated and removed to a substantial degree by the treatment works. These pollutants are biochemical oxygen demand, suspended solids, pH and fecal coliform, phosphorus and its compounds, and nitrogen and its compounds.
(12) "Cooling Water" shall mean the water discharged from any use, such as air conditioning, cooling or refrigeration, or to which the only pollutant added is heat.
(13) "Discharger-Industrial Discharger" shall mean any nonresidential user who discharges an effluent into a POTW by means of pipes, conduits, pumping stations, forcemains, constructed drainage ditches, surface water intercepting ditches, and all constructed devices and appliances appurtenant thereto.
(14) "Garbage" shall mean solid wastes from the preparation, cooking and dispensing of food, and from the handling, storage, processing and sale of produce.
(15) "Hold Tank Waste" shall mean any waste from holding tanks, such as vessels, chemical toilets, campers, trailers, septic tanks, and vacuum pump tank trucks.
(16) "Industrial Waste" shall mean solid, liquid or gaseous waste resulting from any industrial, manufacturing, trade, or business process or from development, recovery, or processing or natural resources.
(17) "Interference" shall mean the inhibition or disruption of the POTW treatment processes or operations which causes a violation of any requirement of the City's NPDES permit. The term includes prevention of sewage sludge use or disposal by the POTW in accordance with 405 of the Act, (33USC1345) or any criteria, guidelines or regulations developed pursuant to the Solid Waste Disposal Act (SWDA), the Clean Air Act, or more stringent state criteria applicable to the method of disposal or use employed by the POTW.
(18) "Major Contributing Industry" shall mean any industrial user of the publicly owned treatment works: a) having a flow of 25,000 gallons or more per average work day; b) having a flow greater than 2 percent of the total flow carried by the municipal system receiving the waste; c) having in its discharge a toxic pollutant in amounts exceeding the desired limits; 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 singularly or in combination with other contributing industries, on that treatment works or upon the quality of effluent from that treatment works.
(19) "National Categorical Pretreatment Standard" shall mean any Federal regulation containing pollutant discharge limits promulgated by the EPA which applies to a specific category of industrial users.
(20) "Natural Outlet" shall mean any outlet into a watercourse, pond, ditch, lake or other body of surface or groundwater.
(21) "Normal Domestic Strength Waste" shall mean wastes which have a BOD of 200 milligrams per liter, suspended solids of 240 milligrams per liter, phosphorus of seven milligrams per liter, having a pH between 6.5 and 9.5 and do not contain a concentration of other constituents which will interfere with the normal wastewater treatment process.
(22) "NPDES Permit" (National Pollutant Discharge Elimination System Permit), according to the Federal Water Pollution Control Act, as amended by Public Law 92-500, prohibits any person from discharging pollutants into a waterway from a point source unless his or her discharge is authorized by permit issued either by the USEPA or by an approved state agency.
(23) "pH" shall mean the logarithm of a reciprocal of the hydrogen ion concentration in moles per liter.
(24) "Pretreatment" or "Treatment" shall mean the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutants or the alteration of pollutant properties in wastewater to a less harmful state prior to or in lieu of discharging or otherwise introducing such pollutants into the sewage works. The reduction can be obtained by physical, chemical or biological processes, or process changes by other means, except as prohibited by 40 CFR Section 403.6(d).
(25) "Pretreatment Standards" shall mean national categorical pretreatment standards, alternative discharge limits, or other Federal, State, or local standards, whichever are applicable.
(26) "Sanitary Sewer" shall mean a sewer which carries sewage and to which storm water, surface water and groundwater are not intentionally admitted.
(27) "Sewage Works" shall mean all facilities for collecting, pumping, treating and disposing of sewage.
(28) "Sewer Service Charge" shall mean the rate charges for providing wastewater collection and treatment service.
(29) "Shall" is mandatory; may is permissive.
(30) "SIC" (Standard Industrial Classification) shall mean a classification pursuant to the Standard Industrial Classification Manual issued by the Executive Office of the President, Office of Management and Budget, 1972.
(31) "Significant Violation" shall mean those violations which remain uncorrected forty-five days after notification of noncompliance, which are a part of a pattern of noncompliance over a twelve-month period, which involve a failure to accurately report noncompliance, or which result in the exercise of the sewage work's emergency authority under 40 CFR 403.8 (f)(2)(vi)(B).
(32) "Slug" shall mean 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 fifteen minutes, more than five times the average twenty-four hour concentration or flows during normal operation.
(33) "Storm Sewer" or "Storm Drain" shall mean a sewer which carries storm and surface waters and drainage, but excludes sewage and polluted industrial wastes.
(34) "Surcharge" shall mean an extra charge to cover the cost of treating, sampling and testing extra strength sewage.
(35) "Suspended Solids" shall mean solids that either float on the surface of, or are in suspension in water, sewage, or other liquids and which are removable by the wastewater treatment process.
(36) "Toxic Pollutant" shall mean any pollutant or combination of pollutants which is or can potentially be harmful to public health or the environment, including those listed as toxic in regulations promulgated by the Administrator of the EPA under provisions of CWA 307(a) or other Acts.
