Cargo Bilge water on bulk carriers can be divided into 2 types – 1. Water containing cargo residues harmful to the marine environment (HME) and; 2. Water containing cargo residues non-harmful to the marine environment (NON-HME). Discharge requirements for NON-HME Cargoes
1. Outside special areas
Discharge allowed greater than or equal to 12NM (vessel enroute)

2. Within Special Areas
Discharge is prohibited

However, there is an exception, discharge is ONLY ALLOWED when both the loading port (next port) and the discharge port (last port), is within special area and NO part of the voyage lies outside the special area AND that both port of loading and discharge does not have shore reception facilities. Due to this reason most of the bulk carriers have now dedicated SLOP tanks so that such wash water can be stored.

Discharge requirements for HME Cargo wash water-
HME cargo wash water – discharge is prohibited both in Special area and outside special area. Such wash water is required to be landed ASHORE ONLY.
