NR 664.1030(1)(1) This subchapter applies to owners and operators of facilities that treat, store or dispose of hazardous wastes (except as provided in s. NR 664.0001). NR 664.1030(2)(2) Except for s. NR 664.1034 (4) and (5), this subchapter applies to process vents associated with distillation, fractionation, thin-film evaporation, solvent extraction or air or steam stripping operations that manage hazardous wastes with organic concentrations of at least 10 ppmw, if these operations are conducted in one of the following: NR 664.1030(2)(b)(b) A unit (including a hazardous waste recycling unit) that is not exempt from licensing under s. NR 662.017 (i.e., a hazardous waste recycling unit that is not a 90-day tank or container) and that is located at a hazardous waste management facility otherwise subject to the licensing requirements of ch. NR 670. NR 664.1030(3)(3) For the owner and operator of a facility subject to this subchapter and who received an operating license under s. 291.25, Stats., prior to December 6, 1996, the requirements of this subchapter shall be incorporated into the license when the license is reissued according to s. NR 670.415 or reviewed according to s. NR 670.050 (4). Until the date when the owner and operator receives an operating license incorporating the requirements of this subchapter, the owner and operator is subject to the requirements of subch. AA of ch. NR 665. NR 664.1030(5)(5) This subchapter does not apply to the process vents at a facility where the facility owner or operator certifies that all of the process vents that would otherwise be subject to this subchapter are equipped with and operating air emission controls according to the process vent requirements in 40 CFR part 60, 61 or 63, and corresponding provisions of ch. NR 440, subch. III of ch. NR 446 and chs. NR 447 to 469. Keep the documentation of compliance under 40 CFR part 60, 61 or 63 and corresponding provisions of ch. NR 440, subch. III of ch. NR 446 and chs. NR 447 to 469 with, or make it readily available with, the facility operating record. NR 664.1030 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06; CR 19-082: am. (2) (b), (c) Register August 2020 No 776, eff. 9-1-20. NR 664.1031NR 664.1031 Definitions. As used in this subchapter: NR 664.1031(1)(1) “Air stripping operation” means a desorption operation employed to transfer one or more volatile components from a liquid mixture into a gas (air) either with or without the application of heat to the liquid. Packed towers, spray towers and bubble-cap, sieve or valve-type plate towers are among the process configurations used for contacting the air and a liquid. NR 664.1031(2)(2) “Bottoms receiver” means a container or tank used to receive and collect the heavier bottoms fractions of the distillation feed stream that remain in the liquid phase. NR 664.1031(3)(3) “Closed-vent system” means a system that is not open to the atmosphere and that is composed of piping, connections and, if necessary, flow-inducing devices that transport gas or vapor from a piece or pieces of equipment to a control device. NR 664.1031(4)(4) “Condenser” means a heat-transfer device that reduces a thermodynamic fluid from its vapor phase to its liquid phase. NR 664.1031(5)(5) “Connector” means flanged, screwed, welded or other joined fittings used to connect 2 pipelines or a pipeline and a piece of equipment. For the purposes of reporting and recordkeeping, connector means flanged fittings that are not covered by insulation or other materials that prevent location of the fittings. NR 664.1031(6)(6) “Continuous recorder” means a data-recording device recording an instantaneous data value at least once every 15 minutes. NR 664.1031(7)(7) “Control device” means an enclosed combustion device, vapor recovery system or flare. Any device the primary function of which is the recovery or capture of solvents or other organics for use, reuse or sale (e.g., a primary condenser on a solvent recovery unit) is not a control device. NR 664.1031(8)(8) “Control device shutdown” means the cessation of operation of a control device for any purpose. NR 664.1031(9)(9) “Distillate receiver” means a container or tank used to receive and collect liquid material (condensed) from the overhead condenser of a distillation unit and from which the condensed liquid is pumped to larger storage tanks or other process units. NR 664.1031(10)(10) “Distillation operation” means an operation, either batch or continuous, separating one or more feed streams into 2 or more exit streams, each exit stream having component concentrations different from those in the feed stream. The separation is achieved by the redistribution of the components between the liquid and vapor phase as they approach equilibrium within the distillation unit. NR 664.1031(11)(11) “Double block and bleed system” means 2 block valves connected in series with a bleed valve or line that can vent the line between the 2 block valves. NR 664.1031(12)(12) “Equipment” means each valve, pump, compressor, pressure relief device, sampling connection system, open-ended valve or line or flange or other connector and any control devices or systems required by this subchapter. NR 664.1031(13)(13) “Flame zone” means the portion of the combustion chamber in a boiler occupied by the flame envelope. NR 664.1031(14)(14) “Flow indicator” means a device that indicates whether gas flow is present in a vent stream. NR 664.1031(15)(15) “First attempt at repair” means to take rapid action for the purpose of stopping or reducing leakage of organic material to the atmosphere using best practices. NR 664.1031(16)(16) “Fractionation operation” means a distillation operation or method used to separate a mixture of several volatile components of different boiling points in successive stages, each stage removing from the mixture some proportion of one of the components. NR 664.1031(17)(17) “Hazardous waste management unit shutdown” means a work practice or operational procedure that stops operation of a hazardous waste management unit or part of a hazardous waste management unit. An unscheduled work practice or operational procedure that stops operation of a hazardous waste management unit or part of a hazardous waste management unit for less than 24 hours is not a hazardous waste management unit shutdown. The use of spare equipment and technically feasible bypassing of equipment without stopping operation are not hazardous waste management unit shutdowns. NR 664.1031(18)(18) “Hot well” means a container for collecting condensate as in a steam condenser serving a vacuum-jet or steam-jet ejector.
