"Ancillary equipment" means any devices, like piping, fittings, flanges, valves, and pumps, that are used to distribute, meter, or control the flow of hazardous waste from its point of generation to storage or treatment tanks, between hazardous waste storage and treatment tanks to a point of disposal onsite, or to a point of shipment for disposal off-site.

"Aquifer" means a geologic formation, group of formations, or part of a formation capable of yielding a significant amount of groundwater to wells or springs.

"Authorized representative" means the person overall responsible for operating a facility or an operational unit (i.e., part of a facility), e.g., the plant manager, superintendent, or person of equivalent responsibility.

"Battery" means a device that consists of one or more electrically connected electrochemical cells that is designed to receive, store, and deliver electric energy. An electrochemical cell is a system consisting of an anode, cathode, and an electrolyte, plus those connections (electrical and mechanical) that are needed to allow the cell to deliver or receive electrical energy. The term battery also includes an intact, unbroken battery from which the electrolyte has been removed.

"Board" means the Illinois Pollution Control Board.

"Boiler" means an enclosed device using controlled flame combustion and having the following characteristics:

Boiler by physical 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 sections must be of integral design. To be of integral design, the combustion chamber and the primary energy recovery sections (like 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 sections are joined only by ducts or connections carrying flue gas is not integrally designed; however, secondary energy recovery equipment (like economizers or air preheaters) need not be physically formed into the same unit as the combustion chamber and the primary energy recovery section. The following units are not precluded from being boilers solely because they are not of integral design: process heaters (units that transfer energy directly to a process stream) and fluidized bed combustion units; and

While in operation, the unit must maintain a thermal energy recovery efficiency of at least 60 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 75 percent of the recovered energy, calculated on an annual basis. In this calculation, no credit may 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

Boiler by designation. The unit is one that the Board has determined, on a case-by-case basis, to be a boiler, after considering the standards in Section 720.132.

"Carbon dioxide stream" means carbon dioxide that has been captured from an emission source (e.g., a power plant), plus incidental associated substances derived from the source materials and the capture process, and any substances added to the stream to enable or improve the injection process.

"Carbon regeneration unit" means any enclosed thermal treatment device used to regenerate spent activated carbon.

"Cathode ray tube" or "CRT" means a vacuum tube, composed primarily of glass, which is the visual or video display component of an electronic device. A "used, intact CRT" means a CRT whose vacuum has not been released. A "used, broken CRT" means glass removed from its housing or casing whose vacuum has been released.

"Central accumulation area" means any on-site area where hazardous waste is accumulating in units subject to either 35 Ill. Adm. Code 722.116 (for an SQG) or 35 Ill. Adm. Code 722.117 (for an LQG). A central accumulation area at an eligible academic entity that chooses to operate under Subpart K of 35 Ill. Adm. Code 722 is also subject to 35 Ill. Adm. Code 722.311 when accumulating unwanted material or hazardous waste.

"Certification" means a statement of professional opinion based upon knowledge and belief.

"Closed portion" means that portion of a facility that an owner or operator has closed in compliance with the approved facility closure plan and all applicable closure requirements. (See also "active portion".)

Containment situation 1 (non-hazardous waste containment):

The unit is in good condition, with no leaks or other continuing or intermittent unpermitted releases of the hazardous secondary materials to the environment, and is designed, as appropriate for the hazardous secondary materials, to prevent unpermitted releases of hazardous secondary materials to the environment.

"Unpermitted releases" are releases that are not covered by a permit (e.g., a permit to discharge to water or air) and may include releases through surface transport by precipitation run-off, releases to soil and groundwater, windblown dust, fugitive air emissions, and catastrophic unit failures;

The unit is properly labeled or otherwise has a system (like a log) to immediately identify the hazardous secondary materials in the unit; and

The unit holds hazardous secondary materials that are compatible with other hazardous secondary materials placed in the unit, is compatible with the materials used to construct the unit and addresses any potential risks of fires or explosions.

Containment situation 2 (hazardous waste containment):

Hazardous secondary materials in units that meet the applicable requirements of 35 Ill. Adm. Code 724 or 725 are presumptively contained.

"Container" means any portable device in which a material is stored, transported, treated, disposed of, or otherwise handled.

BOARD NOTE: A compliance date in Illinois regulations is limited to a date certain on or after the Board has adopted the date by rulemaking. Adoption by rulemaking of the electronic import-export reporting compliance date can occur only after USEPA has made its announcement in the Federal Register. Until the Board has incorporated a date certain by rulemaking, the Board intends that no "electronic import-export reporting compliance date" will apply in the context of the Illinois rules. The federal electronic import-export reporting compliance date named by USEPA, however, may apply as provided by federal law.
