(Section 3 of the Illinois Groundwater Protection Act [415 ILCS 55/3])
"Bedrock" means the solid rock formation immediately underlying any loose superficial material such as soil, alluvium, or glacial drift.
"Beneficially usable waste" means any solid waste from the steel and foundry industries that will not decompose biologically, burn, serve as food for vectors, form a gas, cause an odor, or form a leachate that contains constituents which exceed the limits for this type of waste as specified at 35 Ill. Adm. Code 817.106.
"Board" is the Pollution Control Board established by the Act. [415 ILCS 5/3.130]
"Borrow area" means an area from which earthen material is excavated for the purpose of constructing daily cover, final cover, a liner, a gas venting system, roadways, or berms.
"Chemical waste" means a non-putrescible solid whose characteristics are such that any contaminated leachate is expected to be formed through chemical or physical processes, rather than biological processes, and no gas is expected to be formed as a result.
"Coal combustion power generating facilities" means establishments that generate electricity by combusting coal and which utilize a lime or limestone scrubber system.
"Contaminated leachate" means any leachate whose constituent violate the standards of 35 Ill. Adm. Code 811.202.

"Inert waste" means any solid waste that will not decompose biologically, burn, serve as food for vectors, form a gas, cause an odor, or form a contaminated leachate, as determined in accordance with 35 Ill. Adm. Code 811.202(b). Such inert wastes will include only non-biodegradable and non-putrescible solid wastes. Inert wastes may include, but are not limited to, bricks, masonry, and concrete (cured for 60 days or more).
"Iron slag" means slag.
"Land application unit" means an area where wastes are agronomically spread over or disked into land or otherwise applied so as to become incorporated into the soil surface. For the purposes of this Part and 35 Ill. Adm. Code 811 through 815, a land application unit is not a landfill; however, other Parts of 35 Ill. Adm. Code: Chapter I may apply, and may include the permitting requirements of 35 Ill. Adm. Code 309.
"Landfill" means a unit or part of a facility in or on which waste is placed and accumulated over time for disposal, and which is not a land application unit, a surface impoundment or an underground injection well.

[415 ILCS 5/3.115] (defining "air pollution")
"Municipal solid waste landfill unit" or "MSWLF unit" means a contiguous area of land or an excavation that receives household waste, and that is not a land application, surface impoundment, injection well, or any pile of non-containerized accumulations of solid, non-flowing waste that is used for treatment or storage. A MSWLF unit may also receive other types of RCRA Subtitle D wastes, such as commercial solid waste, non-hazardous sludge, small quantity generator waste and industrial solid waste. Such a landfill may be publicly or privately owned or operated. a MSWLF unit may be a new MSWLF unit, an existing MSWLF unit or a lateral expansion. A sanitary landfill is subject to regulation as a MSWLF if it receives household waste. [415 ILCS 5/3.285] But, a landfill that receives residential lead-based paint waste and which does not receive any other household waste is not a MSWLF unit.
BOARD NOTE: The final sentence of corresponding 40 C.F.R. 258.2 provides as follows: "A construction and demolition landfill that receives residential lead-based paint waste and which does not receive any other household waste is not a MSWLF Unit." A construction and demolition landfill is a type of landfill that does not exist in Illinois, so the Board omitted the reference to "construction and demolition landfill." A landfill in Illinois that receives residential lead-based paint waste and no other type of household waste would be permitted as a chemical waste landfill or a putrescible waste landfill under Subpart C of 35 Ill. Adm. Code 811, as appropriate.

Adm. Code 309, and 35 Ill. Adm. Code 310.
"NPDES permit" means a permit issued under the NPDES program.
"New facility" or "New unit" means a solid waste landfill facility or a unit at a facility, if one or more of the following conditions apply:
It is a landfill or unit exempt from permit requirements pursuant to Section 21(d) of the Act [415 ILCS 5/21(d)] that has not yet accepted any waste as of September 18, 1990;
It is a landfill or unit not exempt from permit requirements pursuant to Section 21(d) of the Act [415 ILCS 5/21(d)] that has no development or operating permit issued by the Agency pursuant to 35 Ill. Adm. Code 807 as of September 18, 1990; or
It is a landfill with a unit whose maximum design capacity or lateral extent is increased after September 18, 1990.
BOARD NOTE: A new unit located in an existing facility will be considered a unit subject to 35 Ill. Adm. Code 814, which references applicable requirements of 35 Ill. Adm. Code 811.
