Sec.  65.84  Operating requirements.

    (a) Closed vent systems or process piping. An owner or operator of a 
transfer rack shall operate it in such a manner that emissions are 
routed through the equipment specified in either paragraph (a)(1) or (2) 
of this section.
    (1) A closed vent system which routes the regulated material vapors 
to a control device as provided in Sec.  65.83(a)(1) and (2).
    (2) Process piping which routes the regulated material vapors to a 
process or a fuel gas system as provided in

Sec.  65.83(a)(4) or to a vapor balance system as provided in Sec.  
65.83(a)(3).
    (b) Control device operation. Whenever regulated material emissions 
are vented to a control device used to comply with the provisions of 
this subpart, such control device shall be operating.
    (c) Tank trucks and railcars. The owner or operator shall load 
regulated material only into tank trucks and railcars that meet one of 
the following two requirements and shall maintain the records specified 
in Sec.  65.87:
    (1) Have a current certification in accordance with the U.S. 
Department of Transportation (DOT) pressure test requirements of 49 CFR 
part 180 for tank trucks and 49 CFR 173.31 for railcars; or
    (2) Have been demonstrated to be vapor-tight within the preceding 12 
months as determined by the procedures in Sec.  65.85(a). Vapor-tight 
means that the pressure in a truck or railcar tank will not drop more 
than 750 pascals (0.11 pound per square inch) within 5 minutes after it 
is pressurized to a minimum of 4,500 pascals (0.65 pound per square 
inch).
    (d) Pressure relief device. The owner or operator of a transfer rack 
subject to the provisions of this subpart shall ensure that no pressure 
relief device in the loading equipment of each tank truck or railcar 
shall begin to open to the atmosphere during loading. Pressure relief 
devices needed for safety purposes are not subject to paragraph (d) of 
this section.
    (e) Compatible system. The owner or operator of a transfer rack 
subject to the provisions of this subpart shall load regulated material 
only to tank trucks or railcars equipped with a vapor collection system 
that is compatible with the transfer rack's closed vent system or 
process piping.
    (f) Loading while systems connected. The owner or operator of a 
transfer rack subject to this subpart shall load regulated material only 
to tank trucks or railcars whose collection systems are connected to the 
transfer rack's closed vent systems or process piping.
