As used in this chapter, unless the context requires otherwise, the following are to mean:
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.
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 (12) month period, and crops, vegetation, forage growth, or postharvest residues are not sustained in the normal growing season over any portion of the lot or facility. Two (2) or more animal feedlots or dairies under common ownership are considered to be a single feeding operation if they adjoin each other, if they use a common area, or if they use a common system for the disposal of wastes.
APPLICANT: Person or persons applying for a special permit for a facility within the Carlin drinking water protection critical areas.
AQUIFER: A water bearing rock, sand or gravel layer that will yield water in a usable quantity to a well or spring.
CARLIN DRINKING WATER PROTECTION CRITICAL AREAS: The zoning districts defined to overlay other zoning districts in the city of Carlin for the protection of the drinking water within the city of Carlin. The districts are defined in subsections 3-16-4(A) and (B) of this chapter.
CLASS I INJECTION 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 INJECTION 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 INJECTION WELL: Wells that inject fluids used in subsurface mining of minerals.
CLASS V INJECTION WELL: Wells not included in the other classes that inject nonhazardous fluid into or above an underground source of drinking water. (The 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 ground water resources or to the natural environment such that it degrades the quality of the resource so as to constitute a hazard and/or impair its use.
DELINEATION: Determining the outline or shape of a drinking water protection area.
DESIGN STANDARD: A control that is implemented for a potential contamination source to prevent discharges to the ground water. Spill protection is an example of a design standard.
DRINKING WATER SOURCE PROTECTION (DWSP) ZONE: The surface and subsurface area surrounding a ground water source of drinking water supplying a public water system through which contaminants are reasonably likely to move toward and reach such ground water source.
GROUND WATER: The water contained in the interconnected pores located below the ground in an aquifer.
GROUND WATER SOURCE: Any well, spring, tunnel, adit, or other underground opening from or through which ground water flows or is pumped from subsurface water bearing formations.
HAZARDOUS MATERIAL: (A) A material that may cause or significantly contribute to a present or potential risk to human health, safety, welfare, to ground water resources or to the natural environment; or
(B) That is defined in the following categories:
1. 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;
2. Carcinogenic: A gas, liquid, or solid which is normally considered to be cancer causing or mutagenic. Examples: PCBs in some waste oils;
3. Explosive: 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;
4. Highly Toxic: A gas, liquid, or solid so dangerous to man as to afford unusual hazard of life. Example: chlorine gas;
5. Moderately Toxic: A gas, liquid or solid that through repeated exposure or in a single large dose can be hazardous to man;
6. 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; or
(C) The following items listed below and byproducts, reaction products, or waste products generated from the use, handling, storage, or production of these items. Examples: 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 still bottoms, inks, printing and photocopying chemicals, 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 into 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.
OVERLAY DISTRICT: A designated area that requires additional zoning restrictions in addition to existing zoning regulations.
PERSON: An individual, corporation, joint venture, incorporated association, public or private corporation, partnership, governmental body or other similar entity, public or private.
POLLUTION SOURCE: Point source discharges of contaminants to ground water or potential discharges of hazardous substances which are stored in containers in excess of "applicable threshold planning quantities" as specified in SARA title III also known as the "emergency planning and community right to know act" (EPCRA), 42 USC section 11011 et seq. (1986), regulations at 40 CFR chapter I, subpart J. Examples of possible pollution sources include, but are not limited to, the following: storage facilities that store liquid forms of extremely hazardous substances, septic tanks, drain fields, class V underground injection wells, landfills, open dumps, land filling of sludge and septage manure piles, salt piles, pit privies, drain lines, and animal feeding operations.

By their design, septic tank/drain field system discharges cannot be controlled with design standards.
SOURCE WATER ASSESSMENT PROGRAM: Section 1453 of the safe drinking water act amendments of 1996 (42 USC section 300 j-13 et seq.) required each state to develop a source water assessment program that will: Delineate areas providing drinking water for all public water supplies (ground water and surface water) and inventory drinking water supplies for potential contaminants which may have adverse effects on human health.
