RULE 260.111 - DEFINITIONS
(Rev. Effective 3/14/89)
As used in this subpart, all terms not defined herein shall have the meaning given them in Subpart A of this Regulation.
(a) "Storage Vessel" means any tank, reservoir, or container used for the storage of petroleum liquids, but does not include:
(b) "Petroleum Liquids" means petroleum, condensate, and any finished or intermediate products manufactured in a petroleum refinery but does not mean Number 2 through Number 6 fuel oils as specified in ASTM-D-396-78, gas turbine fuel oils Numbers 2-GT through 4-GT as specified in ASTM-D-2880-78, or diesel fuel oils Numbers 2-D and 4-D as specified in ASTM-D-975-78. (Effective 5/1/81)
(c) "Petroleum Refinery" means each facility engaged in producing gasoline, kerosene, distillate fuel oils, residual fuel oils, lubricants, or other products through distillation of petroleum or through redistillation, cracking, extracting or reforming of unfinished petroleum derivatives. (Effective 5/1/81)
(d) "Petroleum" means the crude oil removed from the earth and the oils derived from tar sands, shale, and coal.
(e) "Hydrocarbon" means any organic compound consisting predominantly of carbon and hydrogen.
(f) "Condensate" means hydrocarbon liquid separated from natural gas which condenses due to changes in the temperature and/or pressure and remains liquid at standard conditions.
(g) "Custody Transfer" means the transfer of produced petroleum and/or condensate, after processing and/or treating in the producing operations, from storage tanks or automatic transfer facilities to pipelines or any other forms of transportation.
(h) "Drilling and Production Facility" means all drilling and servicing equipment, wells, flow lines, separators, equipment, gathering lines, and auxiliary nontransportation-related equipment used in the production of petroleum but does not include natural gasoline plants.
(i) "True Vapor Pressure" means the equilibrium partial pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute Bulletin 2517, Evaporation Loss from Floating Roof Tanks, 1962.
(j) "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.
(k) "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 such hydrocarbon vapors and gases so as to prevent their emission to the atmosphere.
(l) "Reid Vapor Pressure" is the absolute vapor pressure of volatile crude oil and volatile non-viscous petroleum liquids, except liquified petroleum gases, as determined by ASTM-D-323-82. (Rev. Effective 3/14/89)
