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 which the States bordering the special area shall provide in accordance with Regulation 7 of this Annex, until the concentration of the substance in the effluent to such facility is at or below 0,05 % by weight and until the tank is empty, with the exception of phosphorus, yellow or white, for which the residual concentration shall be 0,005 % by weight. Any water subsequently added to the tank may be discharged into the sea when all the following conditions are satisfied: 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; the discharge is made below the waterline, taking into account the location of the seawater intakes; and 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 m. The discharge into the sea of substances in Category B as defined in Regulation (3)(1)(b) 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: the tank has been prewashed in accordance with the procedure approved by the (flag State) Administration and based on standards developed by the (IMO) and the resulting tank washings have been discharged to a reception facility; 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; the procedures and arrangements for discharge and washings are approved by the (flag State) Administration. Such procedures and arrangements shall be based upon standards developed by the (IMO) and shall ensure that the concentration and rate of discharge of the effluent is such that the concentration of the substance in the wake astern of the ship does not exceed 1 part per million; the discharge is made below the waterline, taking into account the location of the seawater intakes; and 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 m. The discharge into the sea of substances in Category C as defined in Regulation 3(1)(c) 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: 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; the procedures and arrangements for discharge are approved by the (flag State) administration. Such procedures and arrangements shall be based upon standards developed by the (IMO) and shall ensure that the concentration and rate of discharge of the effluent is such that the concentration of the substance in the wake astern of the ship does not exceed 1 part per million; the maximum quantity of cargo discharged from each tank and its associated piping system does not exceed the maximum quantity approved in accordance with the procedures referred to in subparagraph (b) of this paragraph which shall in no case exceed the greater of 1 m^(3) or 1/3000 of the tank capacity in m^(3); the discharge is made below the waterline, taking into account the location of the seawater intakes; and 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 m. Ventilation procedures approved by the (flag State) administration may be used to remove cargo residues from a tank. Such procedures shall be based upon standards developed by the (IMO). Any water subsequently introduced into the tank shall be regarded as clean and shall not be subject to paragraphs 7, 8 or 9 of this Regulation. The discharge into the sea of substances which have not been categorised, 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. Nothing in this regulation shall prohibit a ship from retaining on board the residues from a Category B or C cargo and discharging such residues into the sea outside a special area in accordance with paragraphs 2 or 3 of this Regulation, respectively.
