PART 154--FACILITIES TRANSFERRING OIL OR HAZARDOUS MATERIAL IN BULK--Table 
of Contents
 
                    Subpart E--Vapor Control Systems
 
Sec. 154.850  Operational requirements.

    (a) A facility must receive vapors only from a vessel which has its 
certificate of inspection or certificate of compliance endorsed in 
accordance with 46 CFR 39.10-13(e).
    (b) The following must be performed not more than 24 hours prior to 
each transfer operation:
    (1) All alarms and automatic shutdown systems required by this part 
must be tested; and
    (2) The analyzers required by Sec. 154.820(a), Sec. 154.824 (d) and 
(e) of this subpart must be checked for calibration by use of a span 
gas.
    (c) The position of all valves in the vapor line between the 
vessel's tanks and the facility vapor collection system must be verified 
prior to the start of the transfer operation.
    (d) A tank barge overfill control system that meets the requirements 
of 46 CFR 39.20-9(b) must not be connected to an overfill sensor circuit 
that exceeds the system's rated cable length, inductance, and 
capacitance.
    (e) When vapor is being received from a vessel with inerted cargo 
tanks, the remotely operated cargo vapor shutoff valve required by Sec. 
154.810(a) of this subpart must not be opened until the pressure at the 
facility vapor connection exceeds the pressure on the downstream side of 
the remotely operated cargo vapor shutoff valve.
    (f) The initial cargo transfer rate must not exceed the rate agreed 
upon at the pre-transfer conference required by Sec. 156.120(w) of this 
chapter and 46 CFR 39.30-1(h).
    (g) The cargo transfer rate must not exceed the maximum allowable 
transfer rate as determined by the lesser of the following:
    (1) A transfer rate corresponding to the maximum vapor processing 
rate for the vapor control system, as specified in the facility 
operations manual required by Sec. 154.300 of this chapter; or

    (2) The vessel's maximum transfer rate determined in accordance with 
46 CFR 39.30-1(d).
    (h) While transferring cargo to a vessel connected to a vapor 
control system, compressed air or gas may be used to clear cargo hoses 
and loading arms, but must not be used to clear cargo lines.
    (i) If one of the two analyzers required by Sec. 154.824(d) of this 
subpart becomes inoperable during a transfer operation, the operation 
may continue provided the remaining analyzer remains operational; 
however, no further transfer operations may be started until the 
inoperable analyzer is replaced or repaired.
    (j) Whenever a condition results in a shutdown of the vapor control 
system, the person in charge shall immediately terminate cargo loading.
    (k) If it is suspected that a flare in the vapor control system has 
had a flare-back, or if a flame is detected on the flame arrester 
required by Sec. 154.828(c)(2) of this subpart, the transfer operation 
must be stopped and not be restarted until the flame arrester has been 
inspected and found to be in satisfactory condition.
