"Boiler" means an enclosed device using controlled flame combustion and having the following characteristics:
The unit must have physical provisions for recovering and exporting thermal energy in the form of steam, heated fluids, or heated gases; and
The unit's combustion chamber and primary energy recovery section(s) must be of integral design. To be of integral design, the combustion chamber and the primary energy recovery section(s) (such as waterwalls and superheaters) must be physically formed into one manufactured or assembled unit. A unit in which the combustion chamber and the primary energy recovery section(s) are joined only by ducts or connections carrying flue gas is not integrally designed; however, secondary energy recovery equipment (such as economizers or air preheaters) need not be physically formed into the same unit as the combustion chamber and the primary energy recovery section.

While in operation, the unit must maintain a thermal energy recovery efficiency of at least sixty percent, calculated in terms of the recovered energy compared with the thermal value of the fuel; and
The unit must export and utilize at least seventy-five percent of the recovered energy, calculated on an annual basis. In this calculation, no credit will be given for recovered heat used internally in the same unit. (Examples of internal use are the preheating of fuel or combustion air, and the driving of induced or forced draft fans or feedwater pumps); or

173-303-017(6).
"By-product" means a material that is not one of the primary products of a production process and is not solely or separately produced by the production process.

"Unsaturated zone" means the zone between the land surface and the water table.
"Uppermost aquifer" means the geological formation nearest the natural ground surface that is capable of yielding groundwater to wells or springs. It includes lower aquifers that are hydraulically interconnected with this aquifer within the facility property boundary.
"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.
"User of the electronic manifest system" means a dangerous waste generator, a dangerous waste transporter, an owner or operator of a dangerous waste treatment, storage, recycling or disposal facility, or any other person that:
• Is required to use a manifest to comply with:
- Any federal or state requirement to track the shipment, transportation, and receipt of dangerous waste or other waste material that is shipped from the site of generation to an off-site designated facility for treatment, storage, recycling or disposal; or
- Any federal or state requirement to track the shipment, transportation, and receipt of rejected wastes or regulated container residues that are shipped from a designated facility to an alternative facility, or returned to the generator; and
• Elects to use the system to obtain, complete, and transmit an electronic manifest format supplied by the EPA electronic manifest system; or
• Elects to use the paper manifest form and submits to the system for data processing purposes a paper copy of the manifest (or data from such paper copy), in accordance with WAC
173-303-370 (2)(e). These paper copies are submitted for data exchange purposes only and are not the official copies of record for legal purposes.
