b. Crew members must be properly trained in the use of the EGCS and the system must be kept in good working order, with maintenance up to date and monitoring devices fully operational.

c. The EGCS approval documents, as well as operational and maintenance records for the EGCS must be maintained on board the vessel and made available for inspection upon Port State Control Officer (PSCO) request.

d. While the discharge of wash water from EGCS is currently permitted in Australian waters, vessel owners, operators and Masters are encouraged to avoid discharging wash water within Australian port limits.
