Current through Register Vol. 48, No. 28, July 12, 2024
"Act" means the Surface-Mined Land Conservation and
				  Reclamation Act [225 ILCS 715].
"Airblast" (also known as "air overpressure") means airborne
				  waves resulting from the detonation of explosives. Airblast may be caused by
				  burden movement or the release of expanding gas into the air. Airblast may or
				  may not be audible.
"Attended at all Times" means that the Type 3 magazine and
				  any explosives must always be within the line of sight of, and visible to, a
				  member of the work or blasting crew authorized to enter the magazine.
"Authorized Person" means a person holding a current Illinois
				  Surface Aggregate Blasting License, Illinois Surface Coal Certification,
				  Individual Explosives License, or qualifying for an exemption pursuant to 62
				  Ill. Adm. Code 200.90(d)(5).
"Authorized Representative of the Department" means an
				  employee of the Illinois Department of Natural Resources, Office of Mines and
				  Minerals, Explosives and Aggregate Division, qualified to conduct on-site
				  inspections of blasting operations in order to determine compliance with these
				  regulations.
"Blast" means the detonation of explosives by an operator for
				  a mineral extraction operation.
"Blast Site" means an area where explosive material is
				  handled during loading.
"Blasting Agent" means any material or mixture that:
consists of a fuel and an oxidizer intended for blasting, not
				  otherwise defined as an explosive, provided that the finished product, as mixed
				  and packaged for use or shipment cannot be detonated by means of a No. 8
				  blasting cap, as defined by the Bureau of Alcohol, Tobacco, Firearms, and
				  Explosives, U.S. Department of Treasury 18 U.S.C. Ch. 40, Sec. 841(e), when
				  unconfined; and
is classified as a Division
				  1.5 material under
				  49 CFR
				  173.50.
"Blasting Operations" means the process of shot design,
				  layout, drilling, loading, detonation, and recordkeeping.
"Blasting Zone" means any area within the operation that is
				  designated in writing by the operator to the Department as being the area
				  within which blasting operations will be conducted. The area of a blast within
				  the influence of flying rock, missiles, debris, gases, and airblast.
"Burden" means the distance from an explosive charge to the
				  nearest free or open face at the time of detonation of each hole.
"Cube Root Scaled Distance" means the distance, in feet, from
				  the blast to a specific location, divided by the cube root of the maximum
				  weight of explosives, in pounds, to be detonated within any eight millisecond
				  period.
"Decibel" means the unit of sound overpressure commonly used
				  to measure airblast from the detonation of explosives. It is also measured in
				  pounds per square inch (p.s.i.), and is defined in terms of the overpressure by
				  the equation:
dB = 20 log P/P[0]
where:
dB = sound level in decibels
P = measured overpressure in p.s.i. (lbs./in.(2))
P[o] = 2.9 x 10-9 p.s.i. (lbs./in.(2))
The decibel scale is logarithmic.
"Department" means the Illinois Department of Natural
				  Resources.
"Detonator" means any device containing an initiating or
				  primary explosive that is used for initiating detonation in another explosive
				  material. A detonator may not contain more than 10 grams of total explosives by
				  weight, excluding ignition or delay charges. The term includes, but is not
				  limited to, electric blasting caps of instantaneous and delay types, electronic
				  detonators, blasting caps for use with safety fuse, detonating cord delay
				  connectors, and nonelectric instantaneous and delay blasting caps which use
				  detonating cord, shock tube, or any other replacement for electric leg wires.
				  Unless specifically classified otherwise, detonators are classified as a
				  Division 1.1 material under
				  49 CFR
				  173.5.
"Director" means the Director of the Illinois
				  Department of Natural Resources or such officer, bureau or commission as may
				  lawfully succeed to the powers and duties of such Director.
[225 ILCS
				  715/3 ]
"Electronic Detonator" means a detonator that utilizes stored
				  electrical energy as a means of powering an electronic timing delay
				  element/module and that provides initiation energy for firing the base
				  charge.
"Explosives" means any chemical compound, mixture or device,
				  the primary or common purpose of which is to function by explosion that can be
				  classified as a Division 1.1, 1.2, or 1.3 material under
				  49 CFR
				  173.5 and detonators. The term includes high
				  and low explosives and any explosive devices containing over one quarter ounce
				  of explosive materials.
"Geomembrane" means manufactured membrane liners and barriers
				  of low permeability used to control the migration of fluids or gases.
"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 shall 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).
"Landfill" means a facility permitted by the Illinois
				  Environmental Protection Agency for the disposal of waste on land meeting the
				  requirements of the Resource Conservation and Recovery Act, P.L. 94-580, and
				  regulations thereunder, and without creating nuisances or hazards to public
				  health or safety, by confining the refuse to the smallest practical volume and
				  covering it with a layer of earth at the conclusion of each day's operation, or
				  by such other methods and intervals as the Illinois Pollution Control Board may
				  provide by regulation.
"Licensed Blaster" means an individual licensed by the
				  Department as provided in Section
				  300.237. The person authorized
				  to oversee and approve blasting operations on a blasting site.
"Office of Mines and Minerals" means the subdivision of the
				  Department of Natural Resources charged with regulating the use of explosives
				  in non-coal mineral extraction operations pursuant to Section 6.5 of the
				  Act.
"Operation" means the property limits of any non-coal mineral
				  extraction operation.
"Operator" means any person, firm, partnership or corporation
				  engaged in and controlling a surface mining operation, and includes political
				  subdivisions and instrumentalities of the State of Illinois.
"Particle Velocity" is a measure of ground vibration which
				  describes the velocity at which a particle of ground moves when excited by a
				  seismic wave.
"Person" means any individual, partnership, corporation, or
				  other legal business entity.

				  school, church or commercial or institutional building. Protected structures do
				  not include:
Structures owned by the operator; and

				  and ground vibration requirements granted to the operator.
"Scaled Distance" means the distance, in feet, from the blast
				  to a specified location, divided by the square root of the maximum weight of
				  explosives, in pounds, to be detonated within any eight millisecond
				  period.
"Stemming" is inert material, and used placed in a borehole
				  on top of or between separate charges of explosive material for the purpose of
				  confining explosive materials or to separate charges of explosive material in
				  the same borehole.
