RULE §334.2Definitions

  (42) Farm tank--A tank located on a farm where the stored regulated substance is or will be utilized directly in the farm activities.

  (43) Field-constructed tank--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.

  (44) Flow-through process tank--A tank through which regulated substances flow in a steady, variable, recurring, or intermittent manner during, and as an integral part of, a production process (such as petroleum refining, chemical production, and industrial manufacturing), but specifically excluding any tank used for the static storage of regulated substances prior to their introduction into the production process and any tank used for the static storage of regulated substances which are products or by-products of the production process.

  (45) Free product (or non-aqueous phase liquid)--A regulated substance in its free-flowing non-aqueous liquid phase at standard conditions of temperature and pressure (i.e., that portion of the product not dissolved in water or adhering to soil).

  (46) Gathering lines--Any pipeline, equipment, facility, or building used in the transportation of oil or gas during oil or gas production or gathering operation.

  (47) Hazardous substance--Any substance defined or listed in the federal Comprehensive Environmental Response, Compensation, and Liability Act of 1980, §101(14) (42 United States Code (USC), §§9601, et seq.), and which is not regulated as a hazardous waste under the federal Solid Waste Disposal Act, Subtitle C (42 USC, §§6921, et seq.).

  (48) Hazardous substance underground storage tank (UST) system--A UST system that contains an accumulation of either a hazardous substance, a mixture of two or more hazardous substances, or a mixture of one or more petroleum substances with one or more hazardous substances, and which does not meet the definition of a petroleum UST system in this section.

  (49) Heating oil--A petroleum substance which is typically used in the operation of heating, boiler, or furnace equipment and which either is one of the following seven technical grades of fuel oil: Number 1, Number 2, Number 4-light, Number 4-heavy, Number 5-light, Number 5-heavy, and Number 6; is a residual fuel oil derivative of the refining process (such as Navy Special and Bunker C residual fuel oils); or is another fuel (such as kerosene or diesel) used for heating purposes as a substitute for one of the fuel oils or residual fuel oil derivatives listed in this paragraph.

  (50) Hydraulic fluid--Any regulated substance that is normally used in a hydraulic lift system.

  (51) Hydraulic lift tank--A tank holding hydraulic fluid for a closed-loop mechanical system that uses compressed air and hydraulic fluid to operate lifts, elevators, or other similar devices.

  (52) Impressed current system--A method of cathodic protection where a rectifier is used to convert alternating current to direct current, where the current then flows in a controlled electrically connected circuit to non-sacrificial anodes, then through the surrounding soil or backfill to the protected metallic structure or component, and back to the rectifier.

  (53) In operation--The description of an in-service underground storage tank which is currently being used on a regular basis for its intended purpose.

  (54) In service--The status of an underground storage tank (UST) beginning at the time that regulated substances are first placed into the tank and continuing until the tank is permanently removed from service by means of either removal from the ground, abandonment in-place, or change-in-service. An in-service UST may or may not contain regulated substances, and may be either in operation or out of operation at any specific time.

  (55) Installer--A person who participates in or supervises the installation, repair, or removal of underground storage tanks.

  (56) Inventory control--Techniques used to identify a loss of product that are based on volumetric measurements in the tank and reconciliation of those measurements with product delivery and withdrawal records.

  (57) Jacketed tank--A factory-constructed tank consisting of a single-wall or double-wall steel internal (or primary) tank that is completely enclosed in an external secondary-containment jacket made of noncorrodible material, and which is designed so that releases of stored substances from the internal tank can be contained and monitored within a liquid-tight interstitial space between the internal tank and the external jacket.

  (58) Lender--A state or national bank; a state or federal savings bank; a credit union; a state or federal savings and loan association; a state or federal government agency that customarily provides financing; or an entity that is registered with the Office of Consumer Credit Commissioner under Chapter 7, Title 79, Revised Statutes (Texas Civil Statutes, Article 5069-7.01, et seq.) if the entity is regularly engaged in the business of extending credit and if extending credit represents the majority of the entity's total business activity.

  (59) Liquid trap--A collection device (such as a sump, well cellar, and other trap) which is used in association with oil and gas production, gathering, and extraction operations (including gas production plants) for the purpose of collecting oil, water, and other liquids, and which either may temporarily collect liquids for subsequent disposition or reinjection into a production or pipeline stream, or may collect and separate liquids from a gas stream.

  (60) Leaking petroleum storage tank (LPST) site--A site at which a confirmed release of a petroleum substance from an underground storage tank or aboveground storage tank has occurred. Petroleum substance contamination which results from multiple sources may be deemed as one LPST site by the agency.

  (61) Maintenance--The normal and routine operational upkeep of underground storage tank systems necessary for the prevention of releases of stored regulated substances.

  (62) Monitoring well--An artificial excavation constructed to measure or monitor the quantity or movement of substances, elements, chemicals, or fluids below the surface of the ground. The term does not include any monitoring well which is used in conjunction with the production of oil, gas, or any other minerals.

  (63) Motor fuel--A complex blend of hydrocarbons typically used for the operation of a motor engine, such as and which is one of the following types of fuels: motor gasoline, aviation gasoline, Number 1 or Number 2 diesel fuel, or any blend containing one or more of these substances (for example, motor gasoline blended with alcohol).

  (64) NACE International (NACE) (formerly National Association of Corrosion Engineers)--A nationally recognized organization which provides certifications and standards for corrosion protection services.

  (65) National Fire Protection Association (NFPA)--A nationally recognized organization which provides certifications and standards for fire protection equipment and services.

  (66) New dispenser--A dispenser system is considered new when both the dispenser and the equipment needed to connect the dispenser to the underground storage tank system are installed at an underground storage tank facility. 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.

  (67) New underground storage tank (UST) system--A UST system which is used or designed to contain an accumulation of regulated substances for which installation commenced after December 22, 1988, or an underground storage system which is converted from the storage of materials other than regulated substances to the storage of regulated substances after December 22, 1988.

  (68) Non-aqueous phase liquid (NAPL)--See "Free product (or non-aqueous phase liquid)" as defined in this section.

  (69) Non-commercial purposes--With respect to motor fuel, all purposes except resale.

  (70) Noncorrodible material--A material used in the construction, maintenance, or upgrading of any component of an underground storage tank (UST) system which is designed to retain its physical and chemical properties without significant deterioration or failure for the operational life of the UST system when placed in contact with (and subjected to the resulting electrical and chemical forces associated with) any surrounding soil, backfill, or groundwater, any connected components constructed of dissimilar material, or the stored regulated substance.
