Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part V - Hazardous Wastes and Hazardous Materials › Subpart 1 - Department of Environmental Quality-Hazardous Waste › Chapter 22 - Prohibitions on Land Disposal › Subchapter A - Land Disposal Restrictions › Section V-2203 - Definitions Applicable to This Chapter

Current through Register Vol. 50, No. 6, June 20, 2024
A. When used in this Chapter the following
					 terms have the meanings given below.
Cone of Influence
- that area around the
						well within which increased injection zone pressures caused by injection into
						the waste injection well could drive fluids into an underground source of
						drinking water (USDW).
Confining Zone
- a geological formation,
						group of formations, or part of a formation that is capable of limiting fluid
						movement above an injection zone.
Debris
- solid material exceeding a
						60-mm particle size that is intended for disposal and that is a manufactured
						object, or plant or animal matter, or natural geologic material. However, the
						following materials are not debris: any material for which a specific treatment
						standard is provided in LAC 33:V.Chapter 22.Subchapter A, namely lead acid
						batteries, cadmium batteries, and radioactive lead solids; process residuals
						such as smelter slag and residues from the treatment of waste, wastewater,
						sludges, or air emission residues; and intact containers of hazardous waste
						that are not ruptured and that retain at least 75 percent of their original
						volume. A mixture of debris that has not been treated to the standards provided
						by LAC 33:V.2230 with other material is subject to regulation as debris if the
						mixture is comprised primarily of debris, by volume, based on visual
						inspection.
Duly Authorized Representative
- an
						individual or a position having responsibility for the overall operation of the
						regulated facility or activity, such as the position of plant manager or
						superintendent, or a position of equivalent responsibility (a duly authorized
						representative may be thus be either a named individual or any individual
						occupying a named position), designated or named in writing by one of the
						following:
a. for a corporation, by a responsible corporate officer;
						for the purposes of this Chapter,
responsible corporate
						officer
means:
i. a president, secretary, treasurer, or vice-president
						of the corporation in charge of a principal business function, or any other
						person who performs similar policy or decision-making functions for the
						corporation; or
ii. the manager of one or more manufacturing, production,
						or operating facilities employing more than 250 persons or having gross annual
						sales or expenditures exceeding $25 million (in second-quarter 1980 dollars),
						if authority to sign documents has been assigned or delegated to the manager in
						accordance with corporate procedures;
b. for a partnership or sole proprietorship, by a general
						partner or the proprietor, respectively;
c. for a municipality, state, federal, or other public
						agency, by either a principal executive officer or ranking elected
						official.
Formation
- a body of consolidated or
						unconsolidated rock characterized by a degree of lithologic homogeneity which
						is prevailingly, but not necessarily, tabular and is mappable on the earth's
						surface or traceable in the subsurface.
Halogenated Organic Compounds
or
HOCs
- those compounds having a carbon-halogen bond which are
						listed in LAC 33:V.2299.Appendix, Table 5.
Hazardous Constituent(s)
- those
						constituents listed in LAC 33:V.3105,Table 1.
Hazardous Debris
- debris that contains
						a hazardous waste listed in LAC 33:V.4903 or that exhibits a characteristic of
						hazardous waste identified in LAC 33:V.4901. Any deliberate mixing of
						prohibited hazardous waste with debris that changes its treatment
						classification (i.e., from waste to hazardous debris) is not allowed under the
						dilution prohibition in LAC 33:V.2207.
Injection Interval
- the part of the
						injection zone in which the well is screened, or in which the waste is
						otherwise directly emplaced.
Injection Zone
- a geological formation,
						group of formations, or part of a formation receiving fluids through an
						injection well.
Inorganic Metal-Bearing Waste
- a waste
						for which the department has established treatment standards for metal
						hazardous constituents and which does not otherwise contain significant organic
						or cyanide content as described in LAC 33:V.2207.C.1, and is specifically
						listed in LAC 33:V.2299, Appendix, Table 5.
Land Disposal
- placement in or on the
						land, except in a corrective action management unit or staging pile, and
						includes, but is not limited to, placement in a landfill, surface impoundment,
						waste pile, injection well, land treatment facility, salt-dome formation,
						salt-bed formation, underground mine or cave, or placement in a concrete vault
						or bunker intended for disposal purposes.
Mechanical Integrity
- an injection well
						has mechanical integrity if:
a. there is no significant leak in the casing, tubing, or
						packer; and
b. there is no significant fluid movement into an
						underground source of drinking water through vertical channels adjacent to the
						injection well bore.
Nonwastewaters
- wastes that do not meet
						the criteria for wastewaters defined in this Section.
Petitioner
- a person, or his or her
						duly authorized representative, who has legal authority and responsibility for
						a facility that generates, transports, treats, stores, or disposes of any
						hazardous waste, and who submits a written request to the administrative
						authority for an exemption, extension, or variance to allow the land disposal
						of an otherwise prohibited waste.
Polychlorinated Biphenyls
or
PCBs
- any chemical substance that is limited to the biphenyl
						molecule that has been chlorinated to varying degrees, or any combination of
						substances which contains such substance.
Soil
- unconsolidated earth material
						composing the superficial geologic strata (material overlying bedrock),
						consisting of clay, silt, sand, or gravel size particles as classified by the
						U.S. Soil Conservation Service, or a mixture of such materials with liquids,
						sludges, or solids, that is inseparable by simple mechanical removal processes
						and is made up primarily of soil by volume based on visual inspection. Any
						deliberate mixing of prohibited hazardous waste with soil that changes its
						treatment classification (i.e., from waste to contaminated soil) is not allowed
						under the dilution prohibition in LAC 33:V.2207.
Transmissive Fault or Fracture
- a fault
						or fracture that has sufficient permeability and vertical extent to allow
						fluids to move between formations.
Treatment
-Repealed.
a. solidification of hazardous waste by the addition of
						absorbent material which produces a change only in the physical character of
						the waste without a corresponding change in the chemical character of the
						waste;
b. treatment occurring directly in or on the land, such
						as land treatment, except that treatment may include in situ treatment
						necessary for site remediation;
c. dilution of hazardous waste by the addition of
						nonhazardous material; and/or
d. evaporation in a surface impoundment.
Underground Source of Drinking Water or
						USDW
- an aquifer or its portion:
a. which supplies any public water system; or
b. which contains a sufficient quantity of groundwater to
						supply a public water system, and:
i. currently supplies drinking water for human
						consumption; or
ii. contains fewer that 10,000 mg/L total dissolved
						solids; and
c. which is not an aquifer exempted by the Department of
						Natural Resources, Office of Conservation.
Underlying Hazardous Constituent
-any
						constituent listed in LAC 33:V.2299.Appendix, Table 7, Universal Treatment
						Standards, except fluoride, selenium, sulfides, vanadium, and zinc, which can
						reasonably be expected to be present at the point of generation of the
						hazardous waste at a concentration above the constituent-specific UTS treatment
						standard.
Wastewaters
- wastes that contain less
						than 1 percent by weight total organic carbon (TOC) and less than 1 percent by
						weight total suspended solids (TSS).
B. All other terms are used as defined in
					 Chapter 1 of these regulations.
