(L.N. 177 of 1991)(4) No discharge into the sea shall contain chemicals or other substances in quantities or concentrations which are hazardous to the marine environment or chemicals or other substances introduced for the purposes of circumventing the conditions of discharge prescribed by this regulation. (5) Insofar as any oil or oily mixture has not been unloaded as cargo and may not be discharged into the sea in compliance with paragraph (2) of this regulation, it shall be retained on board and shall only be discharged into reception facilities. Cap 413A reg 14 Oil discharge monitoring and control system and oily-water separating and oil filtering equipment (1) Subject to paragraph (4) of this regulation, every ship of 400 GRT and above but less than 10000 GRT to which these Regulations apply shall be fitted with oil filtering equipment complying with paragraph (5). Any ship to which these Regulations apply which carries ballast water in its bunker fuel tanks shall comply with paragraph (2) of this regulation (notwithstanding that the ship is of less than 10000 GRT) or regulation 24(2). (2) Subject to paragraph (4), every ship of 10000 GRT and above to which these Regulations apply shall be fitted with oil filtering equipment complying with paragraph (6), and with arrangement for an alarm and for automatically stopping any discharge of oily mixtures when the oil content of the effluent exceeds 15 parts per million. (3) Subject to paragraph (4) of this regulation- (a) paragraphs (1) and (2) shall not apply to a ship engaged exclusively- (i) on voyages within the special areas; or (ii) on voyages within the waters of Hong Kong, if- (A) the Director is satisfied that the ship is fitted with a holding tank having a volume adequate for the total retention on board of the oily bilge water; (B) all oily bilge water is retained on board for subsequent discharge to reception facilities; (C) the Director is satisfied that adequate reception facilities are available to receive such oily bilge water at the place of discharge; (D) the IOPP or HKOPP Certificate issued in respect of the ship is endorsed to the effect that the ship is exclusively engaged on voyages of a type specified in sub-sub-paragraph (i) or (ii); and (E) the quantity, time and port of the discharge are recorded in the Oil Record Book; or (L.N. 177 of 1991)(b) ships of less than 400 GRT (other than an oil tanker) shall be equipped so far as practicable and reasonable, (in the case of Hong Kong ships to the satisfaction of the Director), with installations to ensure the storage of oil or oily mixtures on board and their discharge to reception facilities, or to ensure the discharge of such mixtures is in accordance with regulation 12.(4) For existing ships delivered before 6 July 1993 the requirements of this regulation shall not apply until 6 July 1998, so long as these ships operate with oily-water separating equipment (100 ppm equipment) complying with paragraph (7). (5) The oil filtering equipment referred to in paragraph (1) shall be of a design approved as being in accordance with the specification set out in Schedule 3 and shall be such as to ensure that any oily mixture discharged into the sea after passing through the system shall have an oil content which does not exceed 15 ppm. (6) The oil filtering equipment referred to in paragraph (2) shall be- (a) of a design approved as being in accordance with the specification set out in Schedule 3; (b) adequate to ensure that the oil content of any oily mixture discharged into the sea after passing through the system does not exceed 15 ppm; (c) provided with alarm arrangements in accordance with the specification set out in Schedule 3 to indicate when the level of 15 ppm is being exceeded; and (d) provided with arrangements such as will ensure that any discharge of oily mixture is automatically stopped when the oil content of the effluent exceeds 15 ppm.(7) The oily-water separating equipment referred to in paragraph (4) shall be of a design approved as being in accordance with the specification set out in Schedule 3 and shall be such as to ensure that any oily mixture discharged into the sea after passing through the system shall have an oil content of not more than 100 ppm. (7A) (Repealed L.N. 641 of 1994) (8) The oil discharge monitoring and control system referred to in paragraph (4) shall be of a design approved as being in accordance with the specification set out in Schedule 3. The system shall be fitted with a recording device to provide a continuous record of the oil content of the discharge of effluent or oily mixtures in ppm. This record shall be identifiable as to time and date and shall be kept for at least 3 years. The monitoring and control system shall come into operation when there is any discharge of effluent into the sea and shall be such as to ensure that any discharge of oily mixture is automatically stopped when the oil content of the effluent exceeds 100 ppm. On any failure of the monitoring and control system the discharge shall be stopped and the failure shall be noted in the Oil Record Book. The defective unit shall be made operable before the ship commences its next voyage unless it is proceeding to a repair port. |
