Current through June, 2024
As used in this subchapter, all terms not defined herein
					 shall have the meaning given them in HRS chapter 342J and Hawaii Administrative
					 Rules chapters
					 11-260 through 11-266.
"Air stripping operation" is 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.
"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.
"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.
"Condenser" means a heat-transfer device that reduces a
					 thermodynamic fluid from its vapor phase to its liquid phase.
"Connector" means flanged, screwed, welded, or other
					 joined fittings used to connect two 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.
"Continuous recorder" means a data-recording device
					 recording an instantaneous data value at least once every fifteen
					 minutes.
"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.
"Control device shutdown" means the cessation of operation
					 of a control device for any purpose.
"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.
"Distillation operation" means an operation, either batch
					 or continuous, separating one or more feed stream(s) into two or more exit
					 streams, each exit stream having component concentrations different from those
					 in the feed stream(s). The separation is achieved by the redistribution of the
					 components between the liquid and vapor phase as they approach equilibrium
					 within the distillation unit.
"Double block and bleed system" means two block valves
					 connected in series with a bleed valve or line that can vent the line between
					 the two block valves.
"Equipment" means each valve, pump, compressor, pressure
					 relief device, sampling connection system, open-ended valve or line, or flange,
					 and any control devices or systems required by this subchapter.
"Flame zone" means the portion of the combustion chamber
					 in a boiler occupied by the flame envelope.
"Flow indicator" means a device that indicates whether gas
					 flow is present in a vent stream.
"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.
"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.
"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 twenty-four 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.
"Hot well" means a container for collecting condensate as
					 in a steam condenser serving a vacuum-jet or steam-jet ejector.
"In gas/vapor service" means that the piece of equipment
					 contains or contacts a hazardous waste stream that is in the gaseous state at
					 operating conditions.
"In heavy liquid service" means that the piece of
					 equipment is not in gas/vapor service or in light liquid service.
"In light liquid service" means that the piece of
					 equipment contains or contacts a waste stream where the vapor pressure of one
					 or more of the organic components in the stream is greater than 0.3 kilopascals
					 (kPa) at twenty degrees Celsius, the total concentration of the pure organic
					 components having a vapor pressure greater than 0.3 kilopascals (kPa) at twenty
					 degrees Celsius is equal to or greater than twenty percent by weight, and the
					 fluid is a liquid at operating conditions.
"In situ sampling systems" means nonextractive samplers or
					 in-line samplers.
"In vacuum service" means that equipment is operating at
					 an internal pressure that is at least 5 kPa below ambient pressure.
"Malfunction" means any sudden failure of a control device
					 or a hazardous waste management unit or failure of a hazardous waste management
					 unit to operate in a normal or usual manner, so that organic emissions are
					 increased.
"Open-ended valve or line" means any valve, except
					 pressure relief valves, having one side of the valve seat in contact with
					 process fluid and one side open to the atmosphere, either directly or through
					 open piping.
"Pressure release" means the emission of materials
					 resulting from the system pressure being greater than the set pressure of the
					 pressure relief device.
"Process heater" means a device that transfers heat
					 liberated by burning fuel to fluids contained in tubes, including all fluids
					 except water that are heated to produce steam.
"Process vent" means any open-ended pipe or stack that is
					 vented to the atmosphere either directly, through a vacuum-producing system, or
					 through a tank (e.g., distillate receiver, condenser, bottoms receiver, surge
					 control tank, separator tank, or hot well) associated with hazardous waste
					 distillation, fractionation, thin-film evaporation, solvent extraction, or air
					 or steam stripping operations.
"Repaired" means that equipment is adjusted, or otherwise
					 altered, to eliminate a leak.
"Sensor" means a device that measures a physical quantity
					 or the change in a physical quantity, such as temperature, pressure, flow rate,
					 pH, or liquid level.
"Separator tank" means a device used for separation of two
					 immiscible liquids.
"Solvent extraction operation" means an operation or
					 method of separation in which a solid or solution is contacted with a liquid
					 solvent (the two being mutually insoluble) to preferentially dissolve and
					 transfer one or more components into the solvent.
"Startup" means the setting in operation of a hazardous
					 waste management unit or control device for any purpose.
"Steam stripping operation" means a distillation operation
					 in which vaporization of the volatile constituents of a liquid mixture takes
					 place by the introduction of steam directly into the charge.
"Surge control tank" means a large-sized pipe or storage
					 reservoir sufficient to contain the surging liquid discharge of the process
					 tank to which it is connected.
"Thin-film evaporation operation" means a distillation
					 operation that employs a heating surface consisting of a large diameter tube
					 that may be either straight or tapered, horizontal or vertical. Liquid is
					 spread on the tube wall by a rotating assembly of blades that maintain a close
					 clearance from the wall or actually ride on the film of liquid on the
					 wall.
"Vapor incinerator" means any enclosed combustion device
					 that is used for destroying organic compounds and does not extract energy in
					 the form of steam or process heat.
"Vented" means discharged through an opening, typically an
					 open-ended pipe or stack, allowing the passage of a stream of liquids, gases,
					 or fumes into the atmosphere. The passage of liquids, gases, or fumes is caused
					 by mechanical means such as compressors or vacuum-producing systems or by
					 process-related means such as evaporation produced by heating and not caused by
					 tank loading and unloading (working losses) or by natural means such as diurnal
					 temperature changes.
