NR 419.02(18e)(18e) “Waste management unit” means the equipment, structure, or device used to convey, store, treat, or dispose of wastewater streams or affected residuals. Equipment used for recovery is part of a process unit and is not a waste management unit. NR 419.02 NoteNote: Examples of waste management units are wastewater tanks, surface impoundments, individual drain systems, and biological wastewater treatment units. Examples of equipment that may be considered waste management units are containers, air flotation units, oil-water separators and organic-water separators, and organic removal devices such as decanters, strippers, or thin-film evaporation units.
NR 419.02(18m)(18m) “Wastewater stream” means a stream that contains process wastewater. NR 419.02(18s)(18s) “Wastewater tank” means a stationary waste management unit that is designed to contain an accumulation of process wastewater or affected residuals and is constructed primarily of non-earthen materials such as wood, concrete, steel, or plastic. NR 419.02(22)(22) “Water seal” means any seal pot, p-leg trap, or other type of trap filled with water that creates a barrier between the water level of the seal and the atmosphere. The water level of the seal must be maintained in the vertical leg of a drain in order to be considered a water seal. NR 419.02(23)(23) “Wet weather retention basin” means an impoundment or tank that is used to store rainfall runoff that would exceed the capacity of the wastewater treatment system until it can be returned to the wastewater treatment system or, if the water meets the applicable discharge limits, discharged without treatment.

NR 419.03(1)(1) No person may cause, allow or permit organic compound emissions into the ambient air which substantially contribute to the exceeding of an air standard or cause air pollution. NR 419.03(2)(2) No person may cause, allow or permit organic compounds to be used or handled without using good operating practices and taking reasonable precautions to prevent the spillage, escape or emission of organic compounds, solvents or mixtures. Such precautions shall include, but are not limited to: NR 419.03(2)(a)(a) Use of caution to prevent spillage or leakage when filling tanks, trucks or trailers. NR 419.03(2)(b)(b) Use of caution when filling automobile tanks to prevent spillage.

NR 419.04(1)(1) Effective August 1, 1979, no person may cause, allow or permit the disposal of more than 5.7 liters (1.5 gallons) of any liquid VOC waste, or of any liquid, semisolid or solid waste materials containing more than 5.7 liters (1.5 gallons) of any VOC, in any one day from a facility in a manner that would permit their evaporation into the ambient air during the ozone season, except as provided for in s. NR 419.07. This includes, but is not limited to, the disposal of VOC which must be removed from VOC control devices so as to maintain the control devices at their required operating efficiency. NR 419.04(2)(2) Disposal during the ozone season shall be by methods approved by the department, such as incineration, recovery for reuse, or transfer in closed containers to an acceptable disposal facility, such that the quantity of VOC which evaporates into the ambient air does not exceed 15% (by weight) or 5.7 liters (1.5 gallons) in any one day, whichever is larger.
