§ 20-63. Definitions.

Abandoned water well. A well that's use has been permanently discontinued; its pumping equipment has been permanently removed; the well is in such a state of disrepair that it cannot be used to supply water and/or has the potential for transmitting surface contaminants into an aquifer; the well poses potential health or safety hazards, or the well is in such a condition that it cannot be placed in the active, standby, or inactive status.

Applicant. Person or persons applying for a special permit for a facility within the drinking water protection critical area(s).

Animal feedlot/dairies. A lot or facility (other than an aquatic animal production facility) where animals have been, are, or will be stabled or confined and fed or maintained for a total of forty-five (45) days or more in any twelve-month period, and crops, vegetation, forage growth, or post-harvest residues are not sustained in the normal growing season over any portion of the lot or facility.

Aquifer. A water-bearing rock, sand or gravel layer that will yield water in a usable quantity to a well or spring.

Class I well. Wells used to inject hazardous wastes or dispose of nonhazardous industrial waste and treated municipal sewage below the deepest underground source of drinking water.

Class II well. Wells used to inject fluids associated with the production of oil and natural gas or fluids and compounds used for enhanced hydrocarbon recovery. These wells normally inject below the deepest underground source of drinking water (USDW) except in cases where the USDW contains producible quantities of oil or gas.

Class III well. Wells that inject fluids used in subsurface mining of minerals.

Class V well. Wells not included in the other classes that inject nonhazardous fluid into or above an underground source of drinking water. (The seven (7) major types of Class V wells include drainage wells, geothermal reinjection wells, domestic wastewater disposal wells, mineral and fossil fuel recovery related wells, industrial/commercial/utility disposal wells, recharge wells and miscellaneous wells. Class V injection wells also include all large-capacity cesspools and motor vehicle waste disposal wells.)

Contamination. The presence of a material that may cause or significantly contribute to a present or potential risk to human health, safety, welfare, or that is present in groundwater resources or to the natural environment such that it degrades the quality of the resources so as to constitute a hazard and/or impair its use.

Delineation. Determining the outline or shape of a drinking water protection area.

Drinking water protection area. The area around a drinking water source, such as a well or surface water intake, such as delineated by the Louisiana Department of Environmental Quality as part of the source water assessment program. This area is shown on source water assessment program maps and contains the drinking water protection critical area.

Drinking water protection critical area. A one thousand (1,000) feet radial boundary from any water well serving an active public water system.

Groundwater. The water contained in the interconnected pores located below the ground in an aquifer.

Hazardous materials. A material that may cause or significantly contribute to a present or potential risk to human health, safety, welfare, to groundwater resources or to the natural environment; or

That is defined in the following categories:

Carcinogenic. A gas, liquid, or solid which is normally considered to be cancer causing or mutagenic. Example: PCB's in some waste oils.

Corrosive. Any material, whether acid or alkaline, which will cause severe damage to human tissue, or in case of leakage might damage or destroy other containers of hazardous materials and cause the release of their contents. Examples: battery acid and phosphoric acid.

Explosives. A reactive gas, liquid or solid that will vigorously and energetically react uncontrollably if exposed to heat, shock, pressure or combinations thereof. Examples: dynamite, organic peroxides and ammonium nitrate.

Highly toxic. A gas, liquid, or solid so dangerous to man as to afford unusual hazard of life. Example: chlorine gas.

Ignitable. A gas, liquid or solid which may cause fires through friction, absorption of moisture, or which has low flash points. Examples: white phosphorous and gasoline.

Moderately Toxic. A gas, liquid, or solid that through repeated exposure or in a single large dose can be hazardous to man.

The following items listed below and by-products, reaction products, or waste products generated from the use, handling, storage, or production of these items:

Acid and base cleaning solutions, antifreeze and coolants, new or used, arsenic and arsenic compounds, batteries, new and used, brake and transmission fluid, oils/greases/lubricants, brine solution casting and foundry chemicals, caulking agents and sealants, cleaning solvents, cutting fluids, degreasing solvents, disinfectants, electroplating solutions, explosives, fertilizers, food processing wastes, fuels and additives, glues, adhesives, and resins, greases, hydraulic fluid industrial and commercial janitorial supplies, industrial sludges and stillbottoms, inks, printing and photocopying chemical, laboratory chemicals, metal finishing solutions, oils (petroleum based), paints, primers, thinners, dyes, stains, wood preservatives, paint solvents, and paint removing compounds, pesticides and herbicides, plastic resins and catalysts, plasticizers, photo development chemicals, pool chemicals, roofing chemicals and sealers, solders and fluxes, tanning industry chemicals, transformer and capacitor oils/fluids.

Impervious surface. A surface covered by a material that is relatively impermeable to water.

Inactive water well. A well is considered to be inactive if it is not presently operating but is maintained in such a way that it can be put back in operation, with a minimum of effort, to supply water.

Normal household use. Storage or use of a hazardous material in quantities less than five (5) gallons if liquid or fifty (50) pounds if solid.

Person. An individual, corporation, joint venture, incorporated association, public or private corporation, partnership, governmental body or other similar entity, public or private.

Promiscuous dump. Any collection of solid waste either dumped or caused to be dumped or placed on any property either public or private, whether or not regularly used, and not authorized by the administrative authority (Louisiana Department of Environmental Quality).

Public water supply. A water supply that provides water through constructed conveyances to the public for at least fifteen (15) service connections or regularly serves an average of at least twenty-five (24) individuals daily for at least sixty (60) days per year.

Sanitary landfill. A landfill for the disposal of commercial or residential solid waste by deposit in a landfill in layers covered with suitable cover material of a depth and at a frequency adequate to control disease vectors and odors, and in such a manner that minimizes the risk to human health and the environment.

Secured storage. Natural or created barrier to site ingress or egress around the entire perimeter of the hazardous materials storage area.

Well. Any excavation that is drilled, cored, bored, washed, driven, dug, jetted, or otherwise constructed for conveying groundwater to the surface, monitoring groundwater levels or other characteristics, providing cathodic protection, or providing a method of injecting water into the aquifer system from above the earth's surface.
