b.  If there is a large sewage leakage from the ship to the pier, the
discharging CHT system is put into the holding phase. In cases where the
emergency lasts for a prolonged period, the ship's discharge system can be
placed in the overboard mode.
c . In the absence of the shore crew, a man from the ship's crew is
stationed on the pier to guide passersby away from the spill area.
d.  Upon arrival of the shore crew, one man takes over the task of
guiding passersby away from the spill area; the other investigates the source
of the problem, and determines what must be done immediately to cut off the
sewage flow onto the pier, if it is continuing.
e. If the spill occurs while the shore crew is on the pier connecting
or disconnecting a sewage hose, one man warns passersby away from the spill
area. The other man investigates the source of the problem, and takes imme-
diate action to stop the flow of sewage onto the pier.
f.  When the flow of sewage onto the pier has been stopped, one man
continues to warn passersby, while the other flushes down the spill area of
the pier with salt water from the harbor; care should be taken to flush
solids from drain gratings located in the spill area.
g.  If the pier sewer riser and hose exteriors have been soiled by the
spill, they should be flushed off, then washed with a detergent solution and
,
brush.
8.2.4 OPTIONAL DISINFECTION PROCEDURE.  The following steps should be taken
in the event that a decision is made to disinfect the spill area:
a. After the spill area has been flushed thoroughly with salt water,
the area can be disinfected in one of two ways:
(1) Dry phenolic compound solution is aspirated from a tank on
the transport vehicle into salt water, which is used for flushing.
(2) The dry disinfectant is mixed in a pail of water and poured
over the spill area.
b.  If no disinfectant is available at the time of the spill, a liquid
detergent solution may be aspirated from the tank on the truck or applied
directly to the spill area for cleaning after the initial flushing.
c. After a period of at least 15 minutes (an allowance time for action
by the disinfectant or detergents), the entire spill area is flushed off
once again into the harbor.  After the final flushing, the area may be opened
for use, and the shore crew may depart.
8.2.5 HOSE FAILURES.  During the above steps, it may be necessary to replace
a defective hose or hoses as part of the corrective measures.  The ship's
CHT system should have been placed in the holding mode either before or after
arrival of the shore crew. After the initial flushing of the spill area, the
