123 "Thermal treatment" means the treatment of hazardous waste in a device which uses elevated temperatures as the primary means to change the chemical, physical, or biological character or composition of the hazardous waste. Examples of thermal treatment processes are incineration, molten salt, pyrolysis, calcination, wet air oxidation, and microwave discharge. (See also "incinerator" and "open burning.")
124 "Totally enclosed treatment facility" means a facility for the treatment of hazardous waste which is directly connected to an industrial production process and which is constructed and operated in a manner which prevents the release of any hazardous waste or any constituent thereof into the environment during treatment.

125 "Transfer facility" means any transportation related facility including loading docks, parking areas, storage areas and other similar areas where shipments of hazardous waste are held during the normal course of transportation.
126 "Transport vehicle" means a motor vehicle or rail car used for the transportation of cargo by any mode. Each cargo-carrying body (trailer, railroad freight car, etc.) is a separate transport vehicle.
127 "Transportation" means the movement of hazardous waste by air, rail, highway, or water.
128 "Transporter" means a person engaged in the off-site transportation of hazardous waste by air, rail, highway or water.
129 "Treatability study" means a study, other than a means to commercially treat or dispose of hazardous waste, in which a hazardous waste is subjected to a treatment process to determine:
129.01 Whether the waste is amenable to the treatment process;
129.02 What pre-treatment (if any) is required;
129.03 The optimal process conditions needed to achieve the desired treatment;
129.04 The efficiency of a treatment process for a specific waste or wastes; or
129.05 The characteristics and volumes of residuals from a particular treatment process; or
129.06 For the purposes of Chapter 2, 012 and 013 to determine liner compatibility, corrosion, and other material compatibility studies and toxicological and health effect studies.
130 "Treatment" means any method, technique, or process, including neutralization, designed to change the physical, chemical, or biological character or composition of any hazardous waste so as to neutralize such waste, or so as to recover energy or material resources from the waste, or so as to render such waste non-hazardous, or less hazardous; safer to transport, store, or dispose of; or amenable for recovery, amenable for storage, or reduced in volume.
131 "Treatment zone" means a soil area of the unsaturated zone of a land treatment unit within which hazardous constituents are degraded, transformed, or immobilized.
132 "Underground injection" means the subsurface emplacement of fluids through a bored, drilled, or driven well; or through a dug well, where the depth of the dug well is greater than the largest surface dimension. (See also "injection well.")
133 "Underground tank" means a device meeting the definition of "Tank" in this Chapter, whose entire surface area is totally below the surface of and covered by the ground.
134 "Unfit-for-use tank system" means a tank system that has been determined through an integrity assessment or other inspection to be no longer capable of storing or treating hazardous waste without posing a threat of release of hazardous waste to the environment.
135 "United States" means the 50 states, the District of Columbia, the Commonwealth of Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, and the Commonwealth of the Northern Mariana Islands.
136 "Universal waste" means certain hazardous wastes that are defined and managed under the universal waste requirements of Title 128, Chapter 25.
137 "Unsaturated zone" or "zone of aeration" means the zone between the land surface and the water table.
138 "Uppermost aquifer" means the geologic formation nearest the natural ground surface that is an aquifer, as well as lower aquifers that are hydraulically interconnected with this aquifer within the facility's property boundary.
139 "Used oil" means any oil that has been refined from crude oil, or any synthetic oil, that has been used and as a result of such use is contaminated by physical or chemical impurities.
140 "Vessel" includes every description of watercraft, used or capable of being used as a means of transportation on the water.
141 "Wastewater treatment unit" means a device which:
141.01 Is part of a wastewater treatment facility which is subject to regulations under either Section 307(B) of the Clean Water Act or Title 119, Rules and Regulations Pertaining to the Issuance of Permits Under the National Pollutant Discharge Elimination System, Nebraska Department of Environmental Quality; and
141.02 Receives and treats or stores an influent wastewater that is a hazardous waste as defined in Chapter 2, or that generates and accumulates a wastewater treatment sludge which is a hazardous waste as defined in Chapter 2, or treats or stores a wastewater treatment sludge which is a hazardous waste as defined in Chapter 2; and
141.03 Meets the definition of a tank or tank system as defined in this Chapter.
142 "Water (bulk shipment)" means the bulk transportation of hazardous waste which is loaded or carried on board a vessel without containers or labels.
