Ala. Admin. Code r. 335-3-6-.26 - Loading And Storage Of VOC
(1)
For the purposes of this Rule, any stationary storage tank containing a VOC
with a true vapor pressure of 1.5 pounds per square inch absolute or greater
(78 mmHg) under actual storage conditions shall be subject to this
Rule.
(2) No person shall:
(a) place, store, or hold in any stationary
storage vessel of more than 1,000-gallon capacity any VOC unless such vessel is
a pressure tank or is equipped with a permanent submerged fill pipe or bottom
fill pipe (storage vessels in existence prior to January 30, 1973 may employ
portable submerged fill pipe).
(b)
place, store, or hold in any stationary storage vessel of more than 40,000
gallon capacity any VOC unless such vessel is equipped with one of the
following vapor loss control devices, as appropriate:
1. Liquids of intermediate volatility
(liquids having a true vapor pressure under actual storage conditions of
greater than 1.5 psia (78 mmHg) but not greater than 11.1 psia (570 mmHg))
shall be stored in vessels equipped with a floating roof or a vapor recovery
system or an equivalent control system. A floating roof may be a double-deck,
or flexible single-deck, pontoon-type cover which rests upon and is supported
by the stored liquid, and shall be equipped with a closure seal or seals to
close the space between the roof edge and the tank wall. All tank gauging or
sampling devices shall be airtight except when sampling or tank gauging is
performed.
2. Liquids of high
volatility (liquids having a true vapor pressure under actual storage
conditions of greater than 11.1 psia (570 mmHg)) shall be stored in vessels
equipped with vapor recovery systems or equivalent vapor control systems. A
vapor recovery system includes a system of collecting vapors and gases so as to
prevent their emissions to the atmosphere. All tank gauging or sampling devices
shall be airtight except when sampling or tank gauging is performed.
3. Other equipment of equal efficiency for
purposes of air pollution control as may be approved by the Director.
(c) Load any VOCs into any
gasoline tank truck or trailer having a capacity in excess of two hundred (200)
gallons from any terminal or bulk storage facility unless such terminal or
facility is:
1. equipped with:
(i) a vapor collection system or its
equivalent, properly installed, in good working order, with a loading arm
equipped with a vapor collection adaptor of pneumatic, hydraulic, or other
mechanical means which will provide a vapor-tight seal between the adaptor and
the hatch; or
(ii) a loading system
which will result in a submerged fill either with a submerged fill pipe or by
loading from the bottom, and with loading lines equipped with fittings which
make vapor-tight connections and which will close automatically when
disconnected; and
2. for
hatch-loading, equipped with a means to prevent liquid organic compound
drainage from the loading device when it is removed from the hatch of any
transport vessel or transport container.
(3) This Rule shall not apply to crude
petroleum produced, separated, treated, or stored in the field.
