Part 140 sets out the permitted operational discharges into the sea of cargo residues from noxious liquid substances carried in bulk by chemical tankers. The rules set limits on total quantity and concentration of discharges, and specifies minimum water depths and distance from land. More stringent discharge conditions apply to those substances that are categorised as most harmful to the marine environment.

The Part also contains requirements for the carriage of uncategorised noxious liquid substances from New Zealand.

The rules further provide for the reporting of non-operational discharges of noxious liquid substances to the appropriate coastal authorities.

Part 140 gives effect to standards found in Regulations 6 and 13 of Annex II of MARPOL 73/78 and to Protocol I of that instrument.
