Current through Register Vol. 48, No. 28, July 12, 2024
The definitions of 35 Ill. Adm. Code 201 and 211 apply to

				  Ill. Adm. Code 201 and 211, it must take precedence in application of this
				  Part.
"ACGIH" means the American Conference of Governmental
				  Industrial Hygienists.
"Adverse health effect" means a health injury or disease that
				  may be produced by exposure to a contaminant. This includes any decrement in
				  the function of an organ or organ system or any subclinical organ lesion that
				  is likely to lead to a decrement in an organ or organ system function.
"Commercial fuel" means:
Any fuel offered for final sale for use in combustion
				  processes;
Any gaseous or liquid fuel generated as a by-product at a
				  source for which the source has been issued an operating permit to use such
				  fuel internally in combustion processes, including internal combustion engines;
				  or
Any waste derived fuel for which an operating permit has been
				  issued and which represents no more than five percent (.05) by weight on a
				  daily basis of total fuel used in combustion processes by a source.
"Critical gestation days" means the days during which the
				  formation and differentiation of organs and organ systems occurs during
				  embryonic development.
"Fugitive emissions" is defined according to 35 Ill. Adm.
				  Code
				  203.124.
"IARC" means the World Health Organization's International
				  Agency for Research on Cancer.
"IRIS" means the USEPA's Integrated Risk Information
				  System.
"Illinois Toxic Air Contaminant" (ITAC) means any toxic air
				  contaminant listed pursuant to 35 Ill. Adm. Code 232, excluding, specifically:
				  coke oven gas; any hazardous air pollutant (HAP) now or hereafter listed under
				  Section 112(b) of the Clean Air Act (CAA) (1990); and any pollutant or
				  contaminant listed as a compound of concern under the Great Waters and Coastal
				  Waters Program under Section 112(m) of the CAA.
"ITAC Source Report" means the report that the Agency
				  provides to the source that lists data fields for the information required in
				  the emissions report for Subpart D of this Part, and contains the information,
				  if any, that previously has been reported to the Agency for those data
				  fields.
"LC50" means the concentration in air of a contaminant that
				  kills, or is estimated to kill, 50% (.50) of a population of laboratory animals
				  where the exposure is brief (8 hours or less) and where the route of exposure
				  is inhalation.
"LD50" means the dose of a contaminant that kills, or is
				  estimated to kill, 50% (.50) of a population of laboratory animals where the
				  route of exposure is ingestion.
"Lowest observed adverse effect level" means the lowest
				  experimentally determined dose at which a statistically or biologically
				  significant indication of the toxic effect of concern is observed.
"Manufacture" means, for the purposes of Subpart D of this
				  Part, to produce, prepare, or compound a listed ITAC, and includes coincidental
				  production of an ITAC (e.g., as a by-product or impurity) as a result of the
				  manufacture, processing or otherwise use or treatment of one or more chemical
				  substances not an ITAC. An ITAC intentionally incorporated into a product is
				  considered to be manufactured.
"NTP" means the United States Department of Health and Human
				  Services, Public Health Services' National Toxicological Program.
"No observed effect" means the condition where no adverse
				  health effect has been detected.
"Otherwise use" means, for the purposes of Subpart D of this
				  Part, any activity involving a listed ITAC at a source that does not fall
				  within the definition of "manufacture" or "process."
"Process" means, for the purposes of Subpart D of this Part,
				  the preparation of an ITAC after its manufacture for distribution in commerce
				  in the same physical state as, or in a different form or physical state from,
				  that in which it was received by the source, or preparation that produces a
				  change in physical state or chemical form.
"Toxic air contaminant" (TAC) means a contaminant identified
				  pursuant to Section
				  232.200
				  or Section
				  232.501
				  of this Part and listed in Appendix A of this Part.
