(38) Existing underground storage tank (UST) system--A
UST system which is used or designed to contain an accumulation of
regulated substances for which installation either had commenced prior
to December 22, 1988, or had been completed on or prior to December
22, 1988. Installation will be considered to have commenced if the
owner or operator had obtained all federal, state, and local approvals
or permits necessary to begin physical construction at the site or
installation of the tank system, and if either a continuous on-site
physical construction or installation program had begun or the owner
or operator had entered into contractual obligations (which could
not be canceled or modified without substantial loss) which required
that the physical construction at the site or installation of the
tank system was to be completed within a reasonable time.
(39) External release detection--A method of release
detection which includes equipment or procedures designed to effectively
monitor or measure for the presence of regulated substances in the
excavation zone, soil, or other media outside of a single-wall or
double-wall underground storage tank system.
(40) Facility--The site, tract, or other defined area
where one or more underground storage tank systems or one or more
aboveground storage tank systems are located.
(41) Farm--A tract or tracts of land (including all
associated structures and improvements) which are principally devoted
to the raising of agricultural or other types of crops, domestic or
other types of animals, or fish for the production of food, fiber,
or other products or for other useful purposes, including fish hatcheries,
rangeland, and plant nurseries with growing operations, but not including
timber-growing land and operations dedicated primarily to recreational,
aesthetic, or other non-agricultural activities (e.g., golf courses
and parks).
(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
