tank from which a Category A or Category B or Category C substance has been
unloaded shall not be required to be washed and the resultant washings
discharged before the ship leaves the port of unloading as required by those

        substance compatible with it and the tank will not be washed or
        ballasted before such reloading;

   (b)  (i) the tank is neither to be washed nor ballasted at sea; and

        (ii)   the requirements for washing and discharge will be complied
               with in respect of that tank at another port; and

        (iii)  it has been confirmed in writing to the satisfaction of the
               Director, or if the port is not in Hong Kong, of the government
               or other proper authority of the state in which the port is
               situated, that an adequate reception facility will be available
               for the purpose at that other port; or

   (c)  the substance is one for which cleaning by ventilation is stated to be
        appropriate in the ship's Procedures and Arrangements Manual or is
        approved by the Director. (Enacted 1987)
