Sec. 60.111  Definitions.

    As used in this subpart, all terms not defined herein shall have the 
meaning given them in the Act and in subpart A of this part.
    (a) Storage vessel means any tank, reservoir, or container used for 
the storage of petroleum liquids, but does not include:
    (1) Pressure vessels which are designed to operate in excess of 15 
pounds per square inch gauge without emissions to the atmosphere except 
under emergency conditions,
    (2) Subsurface caverns or porous rock reservoirs, or
    (3) 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.
    (b) Petroleum liquids means petroleum, condensate, and any finished 
or intermediate products manufactured in a petroleum refinery but does 
not mean Nos. 2 through 6 fuel oils as specified in ASTM D396-78, 89, 
90, 92, 96, or 98, gas turbine fuel oils Nos. 2-GT through 4-GT as 
specified in ASTM D2880-78 or 96, or diesel fuel oils Nos. 2-D and 4-D 
as specified in ASTM D975-78, 96, or 98a. (These three methods are 
incorporated by reference--see Sec. 60.17.)
    (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.
    (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 External

[[Page 354]]

Floating-Roof Tanks, Second Edition, February 1980 (incorporated by 
reference--see Sec. 60.17).
    (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 nonviscous petroleum liquids, except liquified 
petroleum gases, as determined by ASTM D323-82 or 94 (incorporated by 
reference--see Sec. 60.17).
