4.3.1 A report on alleged deficiencies or on alleged contravention of the discharge
provisions relating to the provisions of MARPOL should be forwarded to the flag State as soon
as possible, preferably no later than 60 days after the observation of the deficiencies or
contravention. Such reports may be made in accordance with the format in appendices 13 or
16, as appropriate. If a contravention of the discharge provisions is suspected, then the
information should be supplemented by evidence of violations which, as a minimum, should
include the information specified in parts 2 and 3 of appendices 3 and 4 of these Procedures.
4.3.2 On receiving a report on alleged deficiencies or alleged contravention of the discharge
provisions, the flag State and, where appropriate, the RO through the flag State Administration,
should, as soon as possible, inform the Party submitting the report of immediate action taken
in respect of the alleged deficiencies or contravention. That Party and the Organization should,
upon completion of such action, be informed of the outcome and details, where appropriate,
be included in the mandatory annual report to the Organization.
