Current through Register Vol. 51, No. 1, July 1, 2024
RELATES TO:
				KRS
				224.20-100,
				224.20-110,

NECESSITY, FUNCTION, AND CONFORMITY:
				KRS
				224.10-100 requires the Environmental and
				Public Protection Cabinet to prescribe administrative regulations for the
				prevention, abatement, and control of air pollution.
				42
				U.S.C. 7410 likewise requires the state to
				implement standards for national primary and secondary ambient air quality.
				This administrative regulation provides for the control of emissions from
				existing storage vessels for petroleum liquids.
Section 1. Definitions. As used in this
			 administrative regulation, all terms not defined in this section shall have the
			 meaning given them in
			 401 KAR
			 61:001.
(1)
			 "Affected facility" means a storage vessel for petroleum liquids which has a
			 storage capacity of greater than 2,195 liters (580 gallons).
(2) "Storage vessel" means any tank,
			 reservoir, or container used for the storage of petroleum liquids, but does not
			 include:
(a) Pressure vessels which are
			 designed to operate in excess of fifteen (15) pounds per square inch gauge
			 without emissions to the atmosphere except under emergency
			 conditions;
(b) Subsurface caverns
			 or porous rock reservoirs; or
(c)
			 Underground tanks if the total volume of petroleum liquids added to and taken
			 from a tank annually does not exceed twice the volume of the
			 tank.
(3) "Petroleum
			 liquids" means crude petroleum, condensate, and any finished or intermediate
			 products manufactured in a petroleum refinery but does not mean Number 2
			 through Number 6 fuel oils, gas turbine fuel oils Numbers 2-GT through 4-GT, or
			 diesel fuel oils Numbers 2-D and 4-D as specified by the cabinet.
(4) "Petroleum refinery" means any facility
			 engaged in producing gasoline, kerosene, distillate fuel oils, residual fuel
			 oils, lubricants, or other products through distillation of petroleum or
			 through redistillation, cracking, or reforming of unfinished petroleum
			 derivatives.
(5) "Crude petroleum"
			 means a naturally occurring mixture which consists of hydrocarbons or sulfur,
			 nitrogen or oxygen derivatives of hydrocarbons and which is a liquid at
			 standard conditions.
(6)
			 "Hydrocarbon" means any organic compound consisting predominantly of carbon and
			 hydrogen.
(7) "Condensate" means
			 hydrocarbon liquid separated from natural gas which condenses due to changes in
			 the temperature or pressure and remains liquid at standard
			 conditions.
(8) "True vapor
			 pressure" means the equilibrium partial pressure exerted by a petroleum liquid
			 as determined in accordance with methods specified by the cabinet.
(9) "Floating roof" means a storage vessel
			 cover consisting of a double deck, pontoon single deck, internal floating cover
			 or covered floating roof, which rests upon and is supported by the petroleum
			 liquid being contained and is equipped with a closure seal or seals to close
			 the space between the roof edge and tank wall.
(10) "Vapor recovery system" means a vapor
			 gathering system capable of collecting all hydrocarbon vapors and gases
			 discharged from the storage vessel and a vapor disposal system capable of
			 processing these hydrocarbon vapors and gases so as to prevent their emission
			 to the atmosphere.
(11) "Reid vapor
			 pressure" is the absolute vapor pressure of volatile crude oil and volatile
			 petroleum liquids, except liquefied petroleum gases, as determined by methods
			 specified by the cabinet.
(12)
			 "Submerged fill pipe" means any fill pipe the discharge of which is entirely
			 submerged when the liquid level is six (6) inches above the bottom of the tank;
			 or when applied to a tank which is loaded from the side, shall mean every fill
			 pipe the discharge opening of which is entirely submerged when the liquid level
			 is two (2) times the fill pipe diameter above the bottom of the tank.
(13) "Classification date" means April 9,
			 1972.
(14) "Custody transfer" means
			 the transfer of produced crude oil or condensate, after processing or treating
			 in the producing operations, from storage tanks or automatic transfer
			 facilities to pipelines or any other forms of transportation.
(15) "External floating roof" means a storage
			 vessel cover in an open top tank consisting of a double deck or pontoon single
			 deck which rests upon and is supported by the petroleum liquid being contained
			 and is equipped with closure seals to close the space between the roof edge and
			 tank shell.
(16) "Internal floating
			 roof" means a cover or roof in a fixed roof tank which rests upon or is floated
			 upon the petroleum liquid being contained, and is equipped with closure seals
			 to close the space between the roof edge and tank shell.
(17) "Liquid-mounted" means a primary seal
			 mounted so that the bottom of the seal covers the liquid surface between the
			 tank shell and the floating roof.
(18) "Vapor-mounted" means a primary seal
			 mounted so that there is an annular vapor space underneath the seal. The
			 annular vapor space is bounded by the bottom of the primary seal, the tank
			 shell, the liquid surface, and the floating roof.
