Current through Register Vol. 35, No. 13, July 16, 2024
A. Terms beginning
				with numerals or the letter "A."
(1) "Above
				ground release" means any release to the surface of the land or to surface
				water. This includes, but is not limited to, releases from the above ground
				portion of an underground storage tank system and releases associated with
				overfills and transfer operations during regulated substance deliveries to or
				dispensing from an UST system.
(2)
				"Above ground storage tank" or "AST" means a single tank or combination of
				manifolded tanks, including pipes connected thereto, that is 1,320 gallons or
				more, and less than 55,000 gallons, is permanently installed, and is used to
				contain petroleum, including crude oil or any fraction thereof that is liquid
				at standard conditions of temperature and pressure of 60 degrees fahrenheit and
				fourteen and seven-tenths pounds per square inch absolute, and the volume of
				which is more than ninety percent above the surface of the ground. Tanks in
				vaults and special enclosures are ASTs. A compartment tank with combined total
				capacity greater than 1,320 gallons and less than 55,000 gallons is an AST and
				for purposes of these regulations is considered to be one tank regardless of
				the number of compartments and the number of regulated substances contained.
				Above ground storage tank does not include (regardless of size) any:
(a) farm, ranch or residential tank used for
				storing motor fuel for noncommercial purposes;
(b) pipeline facility, including gathering
				lines regulated under the federal Natural Gas Pipeline Safety Act of 1968 or
				the federal Hazardous Liquid Pipeline Safety Act of 1979, or that is an
				intrastate pipeline facility regulated under state laws comparable to either
				act;
(c) surface impoundment, pit,
				pond or lagoon;
(d) storm water or
				wastewater collection system;
(e)
				flow-through process tank;
(f)
				liquid trap, tank or associated gathering lines or other storage methods or
				devices related to oil, gas or mining exploration, production, transportation,
				refining, processing or storage, or to oil field service industry
				operations;
(g) tank used for
				storing heating oil for consumptive use on the premises where stored;
(h) tanks, bulk terminals, or related
				pipelines and facilities owned or used by a refinery, natural gas processing
				plant or pipeline company in the regular course of their refining, processing
				or pipeline business; bulk plants are not included in the exemption;
(i) multiple tanks at a facility, that are
				individually less than 1,320 gallons, unless tanks that are siphoned together
				have a cumulative total capacity greater than 1,320 gallons;
(j) pipes connected to any tank exempted by
				Subparagraphs (a) through (i) of this paragraph.
(3) "Accidental release" means any sudden or
				non-sudden release neither expected nor intended by the tank owner or operator
				of petroleum or other regulated substance from a storage tank that results in a
				need for corrective action or compensation for bodily injury or property
				damage.
(4) "Airport hydrant fuel
				distribution system" (also called airport hydrant system) means an AST or UST
				system or a combination thereof 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 regulated tanks from an external source such as a pipeline, barge, rail
				car, or other motor fuel carrier. AST systems with a capacity of 55,000 gallons
				or more associated with airport hydrant fuel distribution systems must comply
				with 20.5.101 NMAC, 20.5.102 NMAC, 20.5.117 NMAC, 20.5.118 NMAC, 20.5.119 NMAC,
				and 20.5.124 NMAC.
(5) "Ancillary
				equipment" means any device including, but not limited to, such devices as
				piping, fittings, flanges, valves, and pumps associated with a storage
				tank.
(6) "Applicable standards"
				means the most relevant target concentrations that legally apply to a
				site.
(7) "AST system" means an
				above ground storage tank and its associated ancillary equipment and
				containment system, if any.
