"Act", for the purposes of this Subpart, means the Illinois
				  Underground Natural Gas Storage Safety Act [ 415 ILCS 160 ].
"Downhole" means the portion of an underground
				  natural gas storage facility from the first flange attaching the wellhead to
				  the pipeline equipment and continuing down the well casing to and including the
				  storage reservoir.
(Section 5 of the Act)
"Emergency Abatement Order" or "EAO" means an order issued by
				  the Department under Subpart H.
"Fault" means a fracture surface or zone of fractures in
				  Earth materials along which there has been vertical and/or horizontal
				  displacement or movement of the strata on opposite sides relative to one
				  another.
"Fluid" means any material or substance that flows or moves,
				  whether semisolid, liquid, gas, or steam.
"Gas Storage Operator", "Operator" or "Owner" means any
				  entity that owns or operates an underground gas storage field.
"Gas Storage Well" means a well drilled for input and/or
				  withdrawal of natural gas or manufactured gas in a gas storage field.
"Natural Gas Incident" or "Incident" means an event that
				  involves a release of stored natural gas from the downhole portion of an
				  underground natural gas storage facility located in this State that:
results in the unintentional estimated gas loss of 3,000,000
				  cubic feet or more;
results in the unintentional estimated gas loss of 500,000
				  cubic feet or more that occurs within 1/8 mile of a dwelling used as a
				  residence, place of business, or place of public assembly;
results in death;
causes personal injury necessitating in-patient
				  hospitalization;
causes property damage in excess of $50,000; or
results in an emergency shutdown of an underground natural
				  gas storage facility.
Activation of an emergency shutdown system for reasons other
				  than an actual emergency does not constitute an incident.
"Observation Well" means a well drilled to monitor subsurface
				  conditions in oil and gas projects or gas storage fields.
"Person" means an individual, firm, joint venture,
				  partnership, corporation, company, limited liability company, firm,
				  association, municipality, cooperative association, or joint stock association.
				  "Person" includes a trustee, receiver, assignee, or personal representative of

				  natural gas storage facility, regardless of whether the escape is underground
				  or to the atmosphere.
"Secretary of Transportation" means the U.S. Secretary of
				  Transportation or his or her designee.
"Sole Source Aquifer" means an aquifer that:
is the sole or principal drinking water source for an area;
				  and
if contaminated, would create a significant hazard to public
				  health as defined in
				  42 USC
				  300h-3(e) and further
				  defined in the Sole Source Aquifer Designation Decision Process, Petition
				  Review Guidance (USEPA; 1987; this incorporation by reference includes no later
				  editions or amendments).
"Stored Natural Gas" means natural gas that is:
transported by pipeline into an underground natural gas
				  storage facility for the purpose of storage prior to transmission back to the
				  pipeline; and
stored within the underground gas storage field.
"Underground Natural Gas Storage Facility" means a facility
				  that stores natural gas in an underground natural gas storage field incident to
				  natural gas transportation, including:
a depleted hydrocarbon reservoir;
an aquifer reservoir;
a solution-mined salt cavern reservoir; and
associated material and equipment used for injection,
				  withdrawal, monitoring, or observation wells, and wellhead equipment, piping,
				  rights-of-way, property, buildings, compressor units, separators, metering
				  equipment, and regulator equipment.
An underground natural gas storage facility is subject to
				  regulation by the Illinois Department of Natural Resources and has not been
				  preempted by the United States Government pursuant to
				  49 USC
				  60104(c).
"Underground Gas Storage Field" means an area of land that is
				  contained within the lowest closing structural contour for which gas can be
				  stored in a subsurface stratum.
"Violation" means a failure to comply with any
				  provision of the Act or any Department order or rule under the Act.
