inspector;
    (4) Remove all passengers from the vessel when the sea valves are 
being examined, if required by the Officer in Charge, Marine Inspection 
(OCMI);
    (5) Allow access to all internal areas of the hull for examination, 
except internal tanks that carry fuel (unless damage or deterioration is 
discovered or suspect), sewage, or potable water. Internal sewage and 
potable water tanks may be examined visually or by non-destructive 
testing to the satisfaction of the attending marine inspector; and
    (6) Meet the requirements in Sec. 176.650 of this part.

by the OCMI.
    (c) If the AHE reveals significant deterioration or damage to the 
vessel's hull plating or structural members, the OCMI must be 
immediately notified. The OCMI may require the vessel be drydocked or 
otherwise taken out of service to further assess the extent of damage or 
to effect permanent repairs if the assessment or repairs cannot be 
completed to the satisfaction of the OCMI while the vessel is 
waterborne.
