A. As used in this
				  Chapter, all terms not defined herein shall have the meanings given them in LAC
				  33:V.109.
Air Stripping Operation
- 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.
Average Volatile Organic Concentration or Average
					 VO Concentration
- the mass-weighted average volatile organic
					 concentration of a hazardous waste as determined in accordance with the
					 requirements of LAC 33:V.4727.
Bottoms Receiver
- a container or tank
					 used to receive and collect the heavier bottoms fractions of the distillation
					 feedstream that remain in the liquid phase.
Closed-Vent System
- 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.
Closure Device
- a cap, hatch, lid, plug,
					 seal, valve, or other type of fitting that blocks an opening in a cover such
					 that when the device is secured in the closed position it prevents or reduces
					 air pollutant emissions to the atmosphere. Closure devices include devices that
					 are detachable from the cover (e.g., a sampling port cap), manually operated
					 (e.g., a hinged access lid or hatch), or automatically operated (e.g., a
					 spring-loaded pressure relief valve).
Condenser
- a heat-transfer device that
					 reduces a thermodynamic fluid from its vapor phase to its liquid phase.
Connector
- 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
- a data-recording
					 device recording instantaneous data values at least every 15 minutes, or more
					 frequently if reasonably available technology exists which will achieve
					 increased recording frequency.
Continuous Seal
- a seal that forms a
					 continuous closure that completely covers the space between the edge of the
					 floating roof and the wall of a tank. A continuous seal may be a vapor-mounted
					 seal, liquid-mounted seal, or metallic shoe seal. A continuous seal may be
					 constructed of fastened segments so as to form a continuous seal.
Control Device
- 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
- the cessation of
					 operation of a control device for any purpose.
Cover
- a device that provides a
					 continuous barrier over the hazardous waste managed in a unit to prevent or
					 reduce air pollutant emissions to the atmosphere. A cover may have openings
					 (such as access hatches, sampling ports, gauge wells) that are necessary for
					 operation, inspection, maintenance, and repair of the unit on which the cover
					 is used. A cover may be a separate piece of equipment which can be detached and
					 removed from the unit or a cover may be formed by structural features
					 permanently integrated into the design of the unit.
Distillate Receiver
- 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
- an operation,
					 either batch or continuous, separating one or more feedstream(s) into two or
					 more exit streams, each exit stream having component concentrations different
					 from those in the feedstream(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
- two block
					 valves connected in series with a bleed valve or line that can vent the line
					 between the two block valves.

					 tank or container, captures organic vapors emitted from the tank or container,
					 and vents the captured vapors through a closed-vent system to a control
					 device.

- each valve, pump, compressor,
					 pressure relief device, sampling connection system, open-ended valve or line,
					 flange, or other connector and any control devices or systems required by this
					 Chapter.

- a pontoon-type or
					 double-deck type cover that rests on the surface of the material managed in a
					 tank with no fixed roof.
First Attempt at Repair
- to take rapid
					 action for the purpose of stopping or reducing leakage of organic material to
					 the atmosphere using best practices.
Fixed Roof
- a cover that is mounted on a
					 unit in a stationary position and does not move with fluctuations in the level
					 of the material managed in the unit.

Flow Indicator
- a device that indicates
					 whether gas flow is present in a vent stream.
Fractionation Operation
- 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.
Hard-Piping
- pipe or tubing that is
					 manufactured and properly installed in accordance with relevant standards and
					 good engineering practices.
Hazardous Waste Management Unit Shutdown
-
					 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 or a scheduled, routine work practice such as cessation
					 of operation on a holiday or weekend is not a hazardous waste management unit
					 shu tdown. The use of spare equipment and technically feasible bypassing of
					 equipment without stopping operation are not hazardous waste management unit
					 shutdowns.
Hot Well
- a container for collecting
					 condensate as in a steam condenser serving a vacuum-jet or steam-jet
					 ejector.
In Gas/Vapor Service
- a piece of
					 equipment that contains or contacts a hazardous waste stream that is in the
					 gaseous state at operating conditions.
In Heavy Liquid Service
- a piece of
					 equipment that is not in gas/vapor service or in light liquid service.
In Light Liquid Service
-a piece of
					 equipment that 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 20°C, the total concentration of the pure organic
					 components having a vapor pressure greater than 0.3 kPa at 20°C is equal to or
					 greater than 20 percent by weight, and the fluid is a liquid at operating
					 conditions.
In Light Material Service
-the container
					 is used to manage a material for which both of the following conditions apply:
					 the vapor pressure of one or more of the organic constituents in the material
					 is greater than 0.3 kilopascals (kPa) at 20°C; and the total concentration of
					 the pure organic constituents having a vapor pressure greater than 0.3 kPa at
					 20°C is equal to or greater than 20 percent by weight.

					 the tank wall and the floating roof continuously around the circumference of
					 the tank.
Malfunction
- any sudden, infrequent, and
					 not reasonably preventable failure of air pollution control equipment, process
					 equipment, or a process to operate in a normal or usual manner. Failures that
					 are caused in part by poor maintenance or careless operation are not
					 malfunctions.
Maximum Organic Vapor Pressure
- the sum
					 of the individual organic constituent partial pressures exerted by the material
					 contained in a tank at the maximum vapor pressure-causing conditions (e.g.,
					 temperature, agitation, pH effects of combining wastes, etc.) reasonably
					 expected to occur in the tank. For the purpose of this Chapter, maximum organic
					 vapor pressure is determined using the procedures specified in LAC
					 33:V.4727.
Metallic Shoe Seal
- a continuous seal
					 that is constructed of metal sheets which are held vertically against the wall
					 of the tank by springs, weighted levers, or other mechanisms and is connected
					 to the floating roof by braces or other means. A flexible coated fabric
					 (envelope) spans the annular space between the metal sheet and the floating
					 roof.
No Detectable Organic Emissions
- no
					 escape of organics to the atmosphere as determined using the procedure
					 specified in LAC 33:V.4727.
Open-Ended Valve or Line
- any valve,
					 except pressure relief valves, having one side of the valve seat in contact
					 with hazardous waste and one side open to the atmosphere, either directly or
					 through open piping.
Point of Waste Origination
- as
					 follows:
a. when the facility owner or operator is the generator of
					 the hazardous waste, the point of waste origination means the point where a
					 solid waste produced by a system, process, or waste management unit is
					 determined to be a hazardous waste as defined in LAC 33:V.109; or
[NOTE: In this case, this term is being used in a manner
					 similar to the use of the term
point of generation
in air

					 Clean Air Act in 40 CFR Parts 60, 61, and 63].
b. when the facility owner and operator are not the
					 generator of the hazardous waste, point of waste origination means the point
					 where the owner or operator accepts delivery or takes possession of the
					 hazardous waste.
Point of Waste Treatment
-the point where
					 a hazardous waste to be treated in accordance with LAC 33:V.4725 exits the
					 treatment process. Any waste determination shall be made before the waste is
					 conveyed, handled, or otherwise managed in a manner that allows the waste to
					 volatilize to the atmosphere.
Pressure Release
-the emission of
					 materials resulting from the system pressure being greater than the set
					 pressure of the pressure relief device.
Process Heater
-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
-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
-equipment is adjusted, or
					 otherwise altered, to eliminate a leak.
Safety Device
-a closure device, such as a
					 pressure relief valve, frangible disc, fusible plug, or any other type of
					 device, which functions exclusively to prevent physical damage or permanent
					 deformation to a unit or its air emission control equipment by venting gases or
					 vapors directly to the atmosphere during unsafe conditions resulting from an
					 unplanned, accidental, or emergency event. For the purpose of this Chapter, a
					 safety device is not used for routine venting of gases or vapors from the vapor
					 headspace underneath a cover such as during filling of the unit or to adjust
					 the pressure in this vapor headspace in response to normal daily diurnal
					 ambient temperature fluctuations. A safety device is designed to remain in a
					 closed position during normal operations and open only when the internal
					 pressure, or another relevant parameter, exceeds the device threshold setting
					 applicable to the air emission control equipment as determined by the owner or
					 operator based on manufacturer recommendations, applicable regulations, fire
					 protection and prevention codes, standard engineering codes and practices, or
					 other requirements for the safe handling of flammable, ignitable, explosive,
					 reactive, or hazardous materials.
Sampling Connection System
-an assembly of
					 equipment within a process or waste management unit used during periods of
					 representative operation to take samples of the process or waste fluid.
					 Equipment used to take non-routine grab samples is not considered a sampling
					 connection system.

					 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.
Start-Up
-the setting in operation of a
					 hazardous waste management unit or control device for any purpose.
Steam Stripping Operation
-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
-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
-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
-any enclosed combustion
					 device that is used for destroying organic compound vapors and does not extract
					 energy in the form of steam or process heat.
Vapor-Mounted Seal
-a continuous seal that
					 is mounted such that there is a vapor space between the hazardous waste in the
					 unit and the bottom of the seal.
Vented
- 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.
Volatile Organic Concentration
or
VO Concentration
-the fraction by weight of the volatile
					 organic compounds contained in a hazardous waste expressed in terms of parts
					 per million (ppmw) as determined by direct measurement or by knowledge of the
					 waste in accordance with the requirements of LAC 33:V.4727. For the purpose of
					 determining the VO concentration of a hazardous waste, organic compounds with a
					 Henry's law constant value of at least 0.1
					 mole-fraction-in-the-gas-phase/mole-fraction-in-the-liquid-phase (0.1 Y/X)
					 (which can also be expressed as 1.8x10-6
					 atmospheres/gram-mole/m3) at 25°C must be included.
					 LAC 33:V.1799.Appendix, Table 1 presents a list of compounds known to have a
					 Henry's law constant value less than the cutoff level.
Waste Determination
-performing all
					 applicable procedures in accordance with the requirements of LAC 33:V.4727 to
					 determine whether a hazardous waste meets standards specified in this Chapter.
					 Examples of a waste determination include performing the procedures in
					 accordance with the requirements of LAC 33:V.4727 to determine the average VO
					 concentration of a hazardous waste at the point of waste origination; the
					 average VO concentration of a hazardous waste at the point of waste treatment
					 and comparing the results to the exit concentration limit specified for the
					 process used to treat the hazardous waste; the organic reduction efficiency and
					 the organic biodegradation efficiency for a biological process used to treat a
					 hazardous waste and comparing the results to the applicable standards; or the
					 maximum volatile organic vapor pressure for a hazardous waste in a tank and
					 comparing the results to the applicable standards.
Waste Stabilization Process
-any physical
					 or chemical process used to either reduce the mobility of hazardous
					 constituents in a hazardous waste or eliminate free liquids as determined by
					 Test Method 9095B (Paint Filter Liquids Test) in Test Methods for Evaluating
					 Solid Waste, Physical/Chemical Methods, EPA Publication SW-846 as incorporated
					 by reference in LAC 33:V.110. A waste stabilization process includes mixing the
					 hazardous waste with binders or other materials and curing the resulting
					 hazardous waste and binder mixture. Other synonymous terms used to refer to
					 this process are waste fixation and waste solidification. This does not include
					 the adding of absorbent materials to the surface of a waste, without mixing,
					 agitation, or subsequent curing, to absorb free liquid.
