Underground Storage tank
"Cathodic protection tester" - ANS - Any individual who can demonstrate an
understanding of the principles and measurements of all common types of cathodic
protection systems as applied to buried or submerged metallic piping and underground
storage tank systems. Such an individual shall possess a current certificate from the
National Association of Corrosion Engineers or the International Code Council,
demonstrating education and experience in soil resistivity, stray current, structure-to soil
potential, and component electrical isolation measurements of buried or submerged
metallic piping and underground storage tank systems.
"Compatible" - ANS - 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
underground storage tank.
"Connected piping" - ANS - All underground piping including valves, elbows, joints,
flanges, and flexible connectors attached to a tank system through which hazardous
substances flow. For the purpose of determining how much piping is connected to any
individual underground storage tank system, the piping that joins two underground
storage tank systems should be allocated equally between them.
"Continuous monitoring" - ANS - A system using equipment which routinely performs
the required monitoring on a periodic or cyclic basis throughout each day.
"Corrosion specialist" - ANS - Any individual 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 metallic piping and underground
storage tank systems. Such an individual shall possess a current certificate from the
National Association of Corrosion Engineers as a corrosion specialist, or be a registered
professional engineer with a current certificate or license requiring education and
experience in corrosion control of buried or submerged metallic piping and underground
storage tank systems.
,"Decommissioned tank" - ANS - An underground storage tank which cannot be used
for one or more of the following reasons: 1) the tank has been filled with an inert solid;
2) the fill pipes have been sealed; or, 3) the piping has been removed.
"Dispenser" - ANS - An aboveground or underground device that is used for the
delivery of a hazardous substance from an underground storage tank. Dispenser
includes metering and delivery devices, and fabricated assemblies located therein.
"Emergency containment" - ANS - A containment system for accidental spills which
are infrequent and unpredictable.
"Existing underground storage tank" - ANS - An underground storage tank installed
prior to January 1, 1984. The term also includes an underground storage tank installed
before January 1, 1987 and which is located on a farm, has a capacity greater than
1,100 gallons, and stores motor vehicle fuel used primarily for agricultural purposes and
not for resale.
"Facility employee" - ANS - An individual who is employed on-site at an underground
storage tank facility, and who may be called upon to respond to spills, overfills, or other
problems associated with the operation of the underground storage tank system. A
"facility employee" is not considered the "operator" as defined in Chapter 6.7 of Division
20 of the Health and Safety Code, although the same individual may hold both
positions.
"Fail safe" - ANS - A monitoring system will shut down the turbine pump in
the event of a power outage, or when the monitoring system fails or is disconnected.
"Farm tank" - ANS - Any one tank or a combination of manifolded tanks that: 1) are
located on a farm; and, 2) holds no more than 1,100 gallons of motor vehicle fuel which
is used primarily for agricultural purposes and is not held for resale.
"Free product" - ANS - A hazardous substance that is present as a non-aqueous
phase liquid (e.g., liquid not dissolved in water).
"Ground water" - ANS - s subsurface water which will flow into a well.
"Hazardous substance" - ANS - A substance which meets the criteria of either
subsection (1) or subsection (2) of section 25281(f) of the Health and Safety Cod
, "Heating oil tank" - ANS - A tank located on a farm or at a personal residence and
which holds no more than 1,100 gallons of home heating oil which is used
consumptively at the premises where the tank is located.
"Holiday" - ANS - When used with respect to underground storage tank coating or
cladding, means a pinhole or void in a protective coating or cladding.
"Hydraulic lift tank" - ANS - A tank holding hydraulic fluid for a closed loop
mechanical system that uses compressed air or hydraulic fluid to operate lifts, elevators,
and other similar devices.
"Inconclusive" - ANS - The conclusion of a statistical inventory reconciliation report
that is not decisive as to whether a release has been detected.
"Independent testing organization" - ANS - An organization which tests products or
systems for compliance with voluntary consensus standards. To be acceptable as an
independent testing organization, the organization shall not be owned or controlled by
any client, industrial organization, or any other person or institution with a financial
interest in the product or system being tested. For an organization to certify, list, or label
products or systems in compliance with voluntary consensus standards, it shall maintain
formal periodic inspections of production of products or systems to ensure that a listed,
certified, or labeled product or system continues to meet the appropriate standards.
"Independent third party" - ANS - independent testing organizations, consulting firms,
test laboratories, not-for-profit research organizations and educational institutions with
no financial interest in the matters under consideration. The term includes only those
organizations which are not owned or controlled by any client, industrial organization, or
any other institution with a financial interest in the matter under consideration.
"Integral secondary containment" - ANS - A secondary containment system
manufactured as part of the underground storage tank
"Interstitial Liquid Level Measurement" - ANS - Method (as the term is used in section
25290.1 of the Health and Safety Code) or "Hydrostatic Monitoring" Method means a
release detection method that continuously monitors the liquid level within a liquid-filled
interstitial space of an underground storage tank. The term includes only those release
detection systems that are capable of detecting a breach in the primary or secondary
containment of the underground storage tank component(s) being monitored before the
hazardous substance stored is released to the environment. To accomplish this, the
liquid in the interstitial space shall be maintained at a pressure greater than the
