HAR §11-280.1-12. Definitions

When used in this chapter, the following terms have the meanings given below: "Aboveground release" means any release to the surface of the land or to surface water. This includes, but is not limited to, releases from the aboveground portion of an UST system and aboveground releases associated with overfills and transfer operations as the regulated substance moves to or from an UST system. "Airport hydrant fuel distribution system" (also called "airport hydrant system") means an UST system which fuels aircraft and operates under high pressure with large diameter piping that typically terminates into one or more hydrants (fill stands). The airport hydrant system begins where fuel enters one or more tanks from an external source such as a pipeline, barge, rail car, or other motor fuel carrier. 280.1-9 8 5 8 4 §11-280.1-12 "Ancillary equipmentu means any devices including, but not limited to, such devices as piping, fittings, flanges, valves, and pumps used to distribute, meter, or control the flow of regulated substances to and from an UST. "Belowground releaseu means any release to the subsurface of the land and to groundwater. This includes, but is not limited to, releases from the belowground portions of an underground storage tank system and belowground releases associated with overfills and transfer operations as the regulated substance moves to or from an underground storage tank. "Beneath the surface of the groundu means beneath the ground surface or otherwise covered with earthen materials. "Cathodic protectionu is a technique to prevent corrosion of a metal surface by making that surface the cathode of an electrochemical cell. For example, a tank system can be cathodically protected through the application of either galvanic anodes or impressed current. "Cathodic protection tester" means a person who can demonstrate an understanding of the principles and measurements of all common types of cathodic protection systems as applied to buried or submerged metal piping and tank systems. At a minimum, such persons must have education and experience in soil resistivity, stray current, structure-to-soil potential, and component electrical isolation measurements of buried metal piping and tank systems. "Class A operatoru means the individual who has primary responsibility to operate and maintain the UST system in accordance with applicable requirements established by the department. The Class A operator typically manages resources and personnel, such as establishing work assignments, to achieve and maintain compliance with regulatory requirements. "Class B operator" means the individual who has day-to-day responsibility for implementing applicable regulatory requirements established by the department. The Class B operator typically implements in-field 280.1-10 3 5 8 4 §11-280.1-12 aspects of operation, maintenance, and associated recordkeeping for the UST system. "Class C operator" means the individual responsible for initially addressing emergencies presented by a spill or release from an UST system. The Class C operator typically controls or monitors the dispensing or sale of regulated substances. "Compatible" means the ability of two or more substances to maintain their respective physical and chemical properties upon contact with one another for the design life of the tank system under conditions likely to be encountered in the UST. "Connected piping" means all underground piping including valves, elbows, joints, flanges, and flexible connectors attached to a tank system through which regulated substances flow. For the purpose of determining how much piping is connected to any individual UST system, the piping that joins two UST systems should be allocated equally between them. "Consumptive use" with respect to heating oil means consumed on the premises. "Containment sump" means a liquid-tight container that protects the environment by containing leaks and spills of regulated substances from piping, dispensers, pumps, and related components in the containment area. Containment sumps may be single walled or secondarily contained and located at the top of tank (tank top or submersible turbine pump sump), underneath the dispenser (under-dispenser containment sump), or at other points in the piping run (transition or intermediate sump). "Corrosion expert" means a person who, by reason of thorough knowledge of the physical sciences and the principles of engineering and mathematics acquired by a professional education and related practical experience, is qualified to engage in the practice of corrosion control on buried or submerged metal piping systems and metal tanks. Such a person must be accredited or certified as being qualified by the National Association of Corrosion Engineers or be a registered professional engineer who has certification or.licensing that includes education and experience in 280.1-11 8 5 8 4 .., §11-280.1-12 corrosion control of buried or submerged metal piping systems and metal tanks. "Department" means the state department of health. "Dielectric material" means a material that does not conduct direct electrical current. Dielectric coatings are used to electrically isolate UST systems from the surrounding soils. Dielectric bushings are used to electrically isolate portions of the UST system (e.g., tank from piping). "Director" means the director of the state department of health. "Dispenser" means equipment located aboveground that dispenses regulated substances from the UST system. "Dispenser system" means the dispenser and the equipment necessary to connect the dispenser to the underground storage tank system. The equipment necessary to connect the dispenser to the underground storage tank system includes check valves, shear valves, unburied risers or flexible connectors, or other transitional components that are underneath the dispenser and connect the dispenser to the underground piping. "Electrical equipment" means underground equipment that contains dielectric fluid that is necessary for the operation of equipment such as transformers and buried electrical cable. "EPA" means the United States Environmental Protection Agency. "Excavation zone" means the volume containing the tank system and backfill material bounded by the ground surface, walls, and floor of the pit and trenches into which the UST system is placed at the time of installation. "Exposure assessment" means a determination regarding the extent of exposure of, or potential for exposure of, individuals to regulated substances from a release from an UST or tank system. An exposure assessment shall be based on factors such as the nature and extent of contamination, the existence of or potential for pathways of human exposure (including 280.1-12 3 5 8 4 1 §11-280.1-12 ground or surface water contamination, air emissions, dermal exposure, soil ingestion, and food chain contamination), the size of the community or communities within the likely pathways of exposure, an analysis of expected human exposure levels with respect to short-term and long-term health effects associated with identified contaminants, and any available recommended exposure or tolerance limits for the contaminants. "Farm tankn is a tank located on a tract of land devoted to the production of crops or raising animals, including fish, and associated residences and improvements. A farm tank must be located on the farm property. Farm includes fish hatcheries, rangeland, and nurseries with growing operations. "Field-constructed tankn means a tank constructed in the field. For example, a tank constructed of concrete that is poured in the field, or a steel or fiberglass tank primarily fabricated in the field is considered field-constructed. "Flow-through process tankn is a tank that forms an integral part of a production process through which there is a steady, variable, recurring, or intermittent flow of materials during the operation of the process. Flow-through process tanks do not include tanks used for the storage of materials prior to their introduction into the production process or for the storage of finished products or by-products from the production process. "Free productn refers to a regulated substance that is present as a non-aqueous phase liquid (e.g., liquid not dissolved in water). "Gathering linesn means any pipeline, equipment, facility, or building used in the transportation of oil or gas during oil or gas production or gathering operations. "Hazardous substanceu means a hazardous substance defined in section 101(14) of the Comprehensive Environmental Response, Compensation and Liability Act of 1980, except any substance regulated as a hazardous waste under chapter 342J, Hawaii Revised Statutes, or the rules adopted thereunder, or Subtitle C of the 280.1-13 3 5 8 4
