    Facility vapor connection means the point in a facility's vapor 
collection system where it connects to a vapor collection hose or the 
base of a vapor collection arm.
    Inerted means the oxygen content of the vapor space in a tank 
vessel's cargo tank is reduced to 8 percent by volume or less in 
accordance with the inert gas requirements of 46 CFR 32.53 or 46 CFR
