The following terms as used in this rule shall have the
				  following meaning unless the context indicates otherwise:
A.
Ancillary equipment.
"Ancillary equipment" means any devices including, but not limited to, piping,
				fittings, flanges, valves, pumps, line leak detection, and meters used to
				distribute, meter, or control the flow of regulated substances to and from an
				underground hazardous substance storage tank.
B.
Board.
"Board" means the
				Maine Board of Environmental Protection.
C.
Cathode.
"Cathode" means the
				electrode of an electrolytic cell at which reduction occurs.
D.
Cathodically protected
.
				"Cathodically protected" means the use of a technique, consistent with the
				National Association of Corrosion Engineers publication, Recommended Practice
				for Control of External Corrosion of Metallic Buried, Partially Buried, or
				Submerged Liquid Storage Systems, RP-02-85, April 1985, to prevent the
				corrosion of a metal surface by making that surface the cathode of an
				electrochemical cell.
E.
Cathodic protection monitoring
. "Cathodic protection monitoring" means a
				process of measuring the structure to electrolyte potential to determine
				whether a cathodically protected structure is being adequately protected
				against corrosion. Cathodic protection monitoring shall be performed according
				to the requirements of Appendix F.
F.
Cathodic protection tester.
"Cathodic protection tester" means a underground storage tank installer
				certified by the Maine Board of Underground Storage Tank Installers, or a
				person who can otherwise demonstrate to the Department's satisfaction an
				understanding of the principles and measurements of all common types of
				cathodic protection systems as applied to buried 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.
G.
Change-in-service.
"Change-in-service" means changing the hazardous
				substance stored in the tank or facility to a different hazardous substance or
				to a non-hazardous substance.
H.
Chemically compatible.
"Chemically compatible" means the ability
				of two or more substances to maintain their respective physical and chemical
				properties upon contact with on, another for extended periods of time under
				varied environmental conditions.
I.
Claims-made policy.
"Claims-made policy" means an insurance policy
				that provides coverage for an occurrence for which a claim arising out of the
				occurrence is made during the term of the policy or any extension
				thereof.
J.
Class one
				liquids
. "Class One liquids" means liquids having a flash point below
				1000[DEGREE] F.
K.
Commissioner.
"Commissioner" means the Commissioner of the Maine
				Department of Environmental Protection.
L.
Continuous electronic
				Monitoring.
"Continuous electronic monitoring" means the use of a
				monitoring device capable of automatic, unattended operation, which will
				provide a clear, audible or visual indication of the presence of liquid
				hazardous substances or hazardous substance vapors outside of a primary
				hazardous substance container.
M.
Corrosion expert.
"Corrosion expert" means a person who is
				approved by the department by reason of thorough knowledge of the physical
				sciences and the principals 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 as being qualified by
				the National Association of Corrosion Engineers or be a Maine registered
				professional engineer who has certification or licensing that includes
				education and experience in corrosion control of buried or submerged metal
				piping systems and metal tanks.
N.
Corrosion-induced leak.
"Corrosion-induced leak" means any
				discharge of a hazardous substance from an underground hazardous substance
				storage facility or tank caused by the deterioration of materials which
				comprise the facility or tank, because of a reaction with the internal or
				external environment of the facility or tank.
O.
Department.
"Department"
				means the Department of Environmental Protection of the State of
				Maine.
P.
Discharge.
"Discharge" means any spilling, leaking, pumping, pouring, emitting, escaping,
				emptying or dumping.
Q.
Existing underground hazardous substance storage facility or tank.
"Existing underground hazardous substance storage facility" and "existing
				underground hazardous substance storage tank" means any facility or tank, fully
				installed prior to the effective date of this rule and the location of which
				has not changed.
R.
Facility.
"Facility" means any underground hazardous substance storage
				tank or tanks located under any land at a single location together with
				associated piping, dispensing or ancillary equipment and used or intended to be
				used, for the storage or supply of hazardous substances, as defined in this
				rule.
S.
Free product.
"Free product" refers to a hazardous substance that is present as a non aqueous
				phase liquid (e.g. a liquid not dissolved in water).
T.
Gallon.
"Gallon" means a unit
				of volume in the U. S. Customary System. used in liquid measure, equal to 4
				quarts, or 3.785 liters.
U.
Hazardous Substance.
"Hazardous substance" means any liquid
				containing a hazardous substance as defined under 38 MRSA §1362, except
				that, for the purpose of this rule, a liquid is not a hazardous substance
				because it contains:
1. a substance
				identified as hazardous waste under chapter 850 of department rules;
2. oil as defined in 38 MRSA §562-A(15);
				or
3. waste oil as defined in 38
				MRSA §1303-C(42).
For the purpose of this rule, "hazardous substance" does not
				  include: liquids containing hazardous substances in such low concentrations
				  that the liquid meets state and federal standards for human consumption; and
				  liquids that the commissioner determines will have no adverse human health or
				  environmental impact if released to the environment.
