Current through June, 2024
As used in this subchapter, all terms not defined herein
					 shall have the meaning given to them by chapter 342J, HRS and chapters 11-260
					 through 11-266 of the Hawaii Administrative Rules.
"Average volatile organic concentration" or "average VO
					 concentration" means the mass-weighted average volatile organic concentration
					 of a hazardous waste as determined in accordance with the requirements of
					 section 11-265-1084.
"Closure device" means 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).
"Continuous seal" means 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.
"Cover" means 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.
"Enclosure" means a structure that surrounds a 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.
"External floating roof" means a pontoon-type or
					 double-deck type cover that rests on the surface of the material managed in a
					 tank with no fixed roof.
"Fixed roof" means 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.
"Floating membrane cover" means a cover consisting of a
					 synthetic flexible membrane material that rests upon and is supported by the
					 hazardous waste being managed in a surface impoundment.
"Floating roof" means a cover consisting of a double deck,
					 pontoon single deck, or internal floating cover which rests upon and is
					 supported by the material being contained, and is equipped with a continuous
					 seal.
"Hard-piping" means pipe or tubing that is manufactured
					 and properly installed in accordance with relevant standards and good
					 engineering practices.
"In light material service" means 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.
"Internal floating roof" means a cover that rests or
					 floats on the material surface (but not necessarily in complete contact with
					 it) inside a tank that has a fixed roof.
"Liquid-mounted seal" means a foam or liquid-filled
					 primary seal mounted in contact with the hazardous waste between the tank wall
					 and the floating roof continuously around the circumference of the tank.
"Malfunction" means 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" means the sum of the
					 individual organic constituent partial pressures exerted by the material
					 contained in a tank, at the maximum vapor pressure-causing conditions (i.e.,
					 temperature, agitation, pH effects of combining wastes, etc.) reasonably
					 expected to occur in the tank. For the purpose of this subchapter, maximum
					 organic vapor pressure is determined using the procedures specified in section
					 11-265-1084(c).
"Metallic shoe seal" means 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" means no escape of
					 organics to the atmosphere as determined using the procedure specified in
					 section 11-265-1084(d).
"Point of waste origination" means as follows:
(1) 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 chapter 11-261.
(2) 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" means the point where a
					 hazardous waste to be treated in accordance with section
					 11-265-1083(c)
					 (2) 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.
"Safety device" means 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 subchapter, 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.
"Single-seal system" means a floating roof having one
					 continuous seal. This seal may be vapor-mounted, liquid-mounted, or a metallic
					 shoe seal.
"Vapor-mounted seal" means 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.
"Volatile organic concentration" or "VO concentration"
					 means 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 section
					 11-265-1084. 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 1.8 x 10-6
					 atmospheres/gram-mole/m3) at 25 degrees Celsius must
					 be included. Appendix VI of this chapter presents a list of compounds known to
					 have a Henry's law constant value less than the cutoff level.
"Waste determination" means performing all applicable
					 procedures in accordance with the requirements of section
					 11-265-1084 to determine whether a
					 hazardous waste meets standards specified in this subchapter. Examples of a
					 waste determination include performing the procedures in accordance with the
					 requirements of section
					 11-265-1084 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" means 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
					 9095 (Paint Filter Liquids Test) in "Test Methods for Evaluating Solid Waste,
					 Physical/Chemical Methods," EPA Publication No. SW-846, Third Edition,
					 September 1986, as amended by Update I, November 15, 1992 (incorporated by
					 reference--refer to section
					 11-260-11 ). 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" or "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.
