Illinois Administrative Code › Title 32 - ENERGY › Part 601 - LICENSING REQUIREMENTS FOR A LOW-LEVEL RADIOACTIVE WASTE DISPOSAL FACILITY › Subpart A - GENERAL PROVISIONS › Section 601.20 - Definitions

Current through Register Vol. 48, No. 28, July 12, 2024
As used in this Part, the following definitions apply:
"Accepted engineering principles and practices" means those
				  engineering principles and practices that are used by engineers when fulfilling
				  their requirements and duties consistent with the specific requirements of this
				  Part and as certified by a Professional Engineer licensed under the
				  Professional Engineering Practice Act [225 ILCS 325 ].
"Active maintenance" means activity needed during the
				  institutional control period to provide reasonable assurance that the
				  performance objectives in Section
				  601.30 are
				  met. Active maintenance includes ongoing activities such as the pumping and
				  treatment of water from a disposal unit and one-time measures such as
				  replacement of a disposal unit cover. Active maintenance does not include minor
				  custodial care such as repair of fences, repair or replacement of monitoring
				  equipment, revegetation, minor additions to soil cover, minor repair of
				  disposal unit covers, and general disposal site upkeep such as mowing
				  grass.
"As low as is reasonably achievable" or "ALARA" means making
				  every reasonable effort to maintain exposures to radiation as far below the
				  dose limits in 32 Ill. Adm. Code: Chapter II, Subchapters b and d as is
				  practical consistent with the purpose for which the licensed or registered
				  activity is undertaken, taking into account the state of technology, the
				  economics of improvements in relation to the state of technology, the economics
				  of improvements in relation to benefits to the public health and safety and
				  other societal and socioeconomic considerations, and in relation to utilization
				  of nuclear energy and licensed or registered sources of radiation in the public
				  interest.
"Buffer zone" means a portion of the disposal site that is
				  controlled by the licensee and that lies under the disposal units and between
				  the disposal units and the boundary of the site.
"Chelating agent" means amine polycarboxylic acids,
				  hydroxycarboxylic acids, glucinic acid and polycarboxylic acids.
"Commence construction" means any clearing of land,
				  excavation or other substantial action that would adversely affect the
				  environment of a disposal facility. The term does not mean disposal site
				  exploration, necessary roads for disposal site exploration, borings to
				  determine foundation conditions, or other preconstruction monitoring or testing
				  to establish background information related to the suitability of the disposal
				  site or the protection of the environment.
"Disposal" means the isolation of waste from the biosphere in
				  a permanent facility designed for that purpose [420 ILCS
				  20/3(f) ].
"Disposal facility" or "facility" means a parcel of land,
				  together with buildings, structures, equipment and improvements on or
				  appurtenant to the land, that is used or is being developed for the disposal of
				  low-level radioactive waste.
"Disposal site" means that portion of a disposal facility
				  that is used for disposal of waste. It consists of disposal units and a buffer
				  zone.
"Disposal unit" means a discrete portion of the disposal site
				  into which waste is placed for disposal.
"Engineered barrier" means a man-made structure or device
				  that is intended to improve the disposal facility's ability to meet the
				  performance objectives in this Part.
"Inadvertent intruder" means a person who might occupy the
				  disposal site after the institutional control period and engage in normal
				  activities, such as agriculture, dwelling construction, or other pursuits in
				  which an individual might be unknowingly exposed to radiation from the
				  waste.
"Institutional control period" means the period of time after
				  the termination of the license during which the State implements an
				  institutional control program based upon the institutional control plan to
				  protect public health and safety and the environment.
"Intruder barrier" means a sufficient depth of cover over the
				  waste that inhibits contact with waste and helps to ensure that radiation
				  exposures to an inadvertent intruder will meet the performance objectives set
				  forth in this Part, or engineered structures that provide equivalent protection
				  to the inadvertent intruder.
"Low-level radioactive waste" or "waste" means radioactive
				  waste not classified as high-level radioactive waste, transuranic waste, spent
				  nuclear fuel or byproduct material as defined in Section 11e(2) of the federal
				  Atomic Energy Act of 1954 (
				  42
				  USC 2014 ) [420 ILCS
				  20/3(k) ].
"Monitoring" means observing and making measurements to
				  provide data to evaluate the performance and characteristics of the disposal
				  facility.
"Post-closure care" means the continued monitoring of the
				  regional disposal facility after closure for the purposes of detecting a need
				  for maintenance, ensuring environmental safety, and determining compliance with
				  applicable licensure and regulatory requirements, and includes undertaking any
				  remedial actions necessary to protect public health and the environment from
				  radioactive releases from the facility [420 ILCS
				  20/3(n) ].
"Release" means any spilling, leaking, pumping, pouring,
				  emitting, emptying, discharging, injecting, escaping, leaching, dumping or
				  disposing into the environment of low-level radioactive waste [420 ILCS
				  20/3(p) ].
"Remedial action" means those actions taken in the event of a
				  release or threatened release of low-level radioactive waste into the
				  environment, to prevent or minimize the release of the waste so that it does
				  not migrate to cause substantial danger to present or future public health or
				  welfare or the environment. The term includes, but is not limited to, actions
				  at the location of the release such as storage, confinement, perimeter
				  protection using dikes, trenches or ditches, clay cover, neutralization,
				  cleanup of released low-level radioactive wastes, recycling or reuse, dredging
				  or excavations, repair or replacement of leaking containers, collection of
				  leachate and runoff, provision of alternative water supplies and any monitoring
				  reasonably required to assure that these actions protect human health and the
				  environment. [420 ILCS
				  20/3(q) ]
"Shallow land burial" means a land disposal facility in which
				  radioactive waste is disposed of in or within the upper 30 meters of the
				  earth's surface. However, this definition shall not include an enclosed,
				  engineered, structurally re-enforced and solidified bunker that extends below
				  the earth's surface. [420 ILCS
				  20/3(r) ]
"Site closure and stabilization" means those actions that are
				  taken upon completion of operations that prepare the disposal site for
				  institutional control and that assure that the disposal site will remain stable
				  and will not need ongoing active maintenance.
