The discharge into the sea of substances in Category A as defined in Regulation 3(1)(a) of this Annex or of those provisionally assessed as such or ballast water, tank washings, or other residues or mixtures containing such substances shall be prohibited. If tanks containing such substances or mixtures are to be washed, the resulting residues shall be discharged to a reception facility until the concentration of the substance in the effluent to such facility is as at or below 0.1 % by weight and until the tank is empty, with the exception of Phosphorus, yellow or white for which the residual concentration shall be at 0.01 % by weight. Any water subsequently added to the tank may be discharged into the sea when all the following conditions are also satisfied: |
| (a) |
the ship is proceeding en route at a speed of at least 7 knots in the case of self-propelled ships or at least 4 knots in the case of ships which are not self-propelled; |

| (e) |
the discharge is made at a distance of not less than 12 nautical miles from the nearest land and in a depth of water of not less than 25 metres. |
| (4) |
The discharge into the sea of substances in Category D as defined in Regulation 3(1)(d) of this Annex, or of those provisionally assessed as such, or ballast water, tank washings, or other residues or mixtures containing such substances shall be prohibited except when all the following conditions are satisfied: |

| (6) |
The discharge into the sea of substances which have not been categorized, provisionally assessed, or evaluated as referred to in Regulation 4(1) of this Annex, or of ballast water, tank washings, or other residues or mixtures containing such substances shall be prohibited. |
