Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part XV - Radiation Protection › Chapter 13 - Licensing Requirements for Land Disposal of Radioactive Waste › Subchapter A - General Provisions › Section XV-1302 - Definitions

Current through Register Vol. 50, No. 6, June 20, 2024
A. As used in this
				  Chapter, the following definitions apply.
Active Maintenance
- any significant
					 remedial activity needed during the period of institutional control to maintain
					 a reasonable assurance that the performance objectives in LAC 33:XV.1319 and
					 1320 are met. Such active maintenance includes ongoing activities such as the
					 pumping and treatment of water from a disposal unit or one-time measures such
					 as replacement of a disposal unit cover. Active maintenance does not include
					 custodial activities such as repair of fencing, 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.
Buffer Zone
- 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
- amine polycarboxylic
					 acids, hydroxy-carboxylic acids, gluconic acid, and polycarboxylic
					 acids.
Commencement of Construction
- any
					 clearing of land, excavation, or other substantial action that would adversely
					 affect the environment of a land 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 environmental values.
Custodial Agency
- an agency of the
					 government designated to act on behalf of the government owner of the disposal
					 site.
Disposal
- the isolation of wastes from
					 the biosphere inhabited by man and containing his food chains by emplacement in
					 a land disposal facility.
Disposal Site
- that portion of a land
					 disposal facility which is used for disposal of waste. It consists of disposal
					 units and a buffer zone.
Disposal Unit
- a discrete portion of the
					 disposal site into which waste is placed for disposal. For near-surface
					 disposal, the unit is usually a trench.
Engineered Barrier
- a man-made structure
					 or device that is intended to improve the land disposal facility's ability to
					 meet the performance objectives in this Chapter.
Explosive Material
- any chemical
					 compound, mixture, or device which produces a substantial instantaneous release
					 of gas and heat spontaneously or by contact with sparks or flame.
Geologic Repository
- a system that is
					 intended to be used, or may be used, for the disposal of radioactive waste in
					 excavated geologic media. A geologic repository includes the geologic
					 repository operations area and the portion of the geologic setting that
					 provides isolation of the radioactive waste.
Hazardous Waste
- those wastes designated
					 as hazardous by U.S. Environmental Protection Agency regulations in 40 CFR Part
					 261.
Hydrogeologic Unit
- any soil or rock unit
					 or zone which by virtue of its porosity or permeability, or lack thereof, has a
					 distinct influence on the storage or movement of groundwater.
Inadvertent Intruder
- a person who might
					 occupy the disposal site after closure 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.
Intruder Barrier
- 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 Chapter or engineered structures that provide
					 equivalent protection to the inadvertent intruder.
Land Disposal Facility
- the land,
					 buildings, structures, and equipment that are intended to be used for the
					 disposal of radioactive wastes. For purposes of this Chapter, a
geologic repository
is not considered a
land disposal
					 facility
.
Monitoring
- observing and making
					 measurements to provide data to evaluate the performance and characteristics of
					 the disposal site.
Near-Surface Disposal Facility
- a land
					 disposal facility in which waste is disposed of within approximately the upper
					 30 meters of the earth's surface.
Pyrophoric Liquid
- any liquid that
					 ignites spontaneously in dry or moist air at or below 130°F
					 (54.4&°C). A pyrophoric solid is any solid material, other than one
					 classed as an explosive, which under normal conditions, is liable to cause
					 fires through friction, retained heat from manufacturing or processing, or
					 which can be ignited readily and, when ignited, burns so vigorously and
					 persistently as to create a serious transportation, handling, or disposal
					 hazard. Included are spontaneously combustible and water-reactive
					 materials.
Site Closure and Stabilization
- those
					 actions that are taken upon completion of operations that prepare the disposal
					 site for custodial care and that assure that the disposal site will remain
					 stable and will not need ongoing active maintenance.
Stability
- structural stability.
Surveillance
- monitoring and observation
					 of the disposal site for purposes of visual detection of need for maintenance,
					 custodial care, evidence of intrusion, and compliance with other license and
					 regulatory requirements.
Waste
-those low-level radioactive wastes
					 containing source, special nuclear, or byproduct material that are acceptable
					 for disposal in a land disposal facility. For the purposes of this definition,
					 low-level radioactive waste has the same meaning as in the Low-Level
					 Radioactive Waste Policy Act, P.L. 96-573, that is radioactive waste not
					 classified as high-level radioactive waste, transuranic waste, spent nuclear
					 fuel, or byproduct material as defined in section 11. e (2) of the Atomic
					 Energy Act (uranium or thorium tailings and waste) and LAC 33:XV.102,
byproduct material
, 3, 4, and 5.

					 Promulgated in accordance with
					 R.S.
					 30:2001 et seq., and
