Application
Unless expressly provided otherwise, the provisions of this Annex shall apply to all ships certified to carry noxious liquid substances in bulk.
Regulation 6 Categorization and listing of noxious liquid substances and other substances
For the purpose of the regulations of this Annex, noxious liquid substances shall be divided into four categories as follows:
Category X:
Noxious liquid substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a major hazard to either marine resources or human health and, therefore, justify the prohibition of the discharge into the marine environment
Category Y:
Noxious liquid substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a hazard to either marine resources or human health or cause harm to amenities or other legitimate uses of the sea and therefore justify a limitation on the quality and quantity of the discharge into the marine environment.
Category Z:
Noxious liquid substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a minor hazard to either marine resources or human health and therefore justify less stringent restrictions on the quality and quantity of the discharge into the marine environment;
Other substances:
Substances indicated as OS (Other substances) in the pollution category column of chapter 18 of the International Bulk Chemical Code which have been evaluated and found to fall outside category X, Y or Z of this Annex. At present, considered to present no harm to marine resources, human health, amenities or other legitimate uses of the sea when discharged into the sea from tank cleaning or deballasting operations.
Regulations 8 Surveys
Ships carrying noxious liquid substances in bulk shall be subject to the surveys specified below:
1. An initial survey
before the ship is put in service or before the Certificate required (An International Pollution Prevention Certificate for the Carriage of Noxious Liquid Substances in Bulk) is issued for the first time. It shall include a complete survey of its structure, equipment, systems, fittings, arrangements and material in so far as the ship is covered by this Annex. This survey shall be such as to ensure that the structure, equipment, systems, fittings, arrangements and material fully comply with the applicable requirements of this Annex.
2. A renewal survey
at intervals specified by the Administration, but not exceeding 5 years. The renewal survey shall be such as to ensure that the structure, equipment, systems, fittings, arrangements and material fully comply with applicable requirements of this Annex.
3. An intermediate survey
within 3 months before or after the second anniversary date or within 3 months before or after the third anniversary date of the Certificate. The intermediate survey shall be such as to ensure that the equipment and associated pump and piping systems fully comply with the applicable requirements of this Annex and are in good working order. Such survey shall be endorsed on the certificate.
4. An annual survey
within 3 months before or after each anniversary date of the Certificate. It includes a general inspection of the structure, equipment, systems, fittings, arrangements and material in order to ensure that they have been maintained and remain satisfactory for the service. Such survey shall be endorsed on the certificate.
5. An additional survey
shall be made after any important repairs or renewals. The survey shall be such as to ensure that the necessary repairs or renewals have been effectively made, that the material and workmanship of such repairs or renewals are in all respects satisfactory and that the ship complies in all respects with the requirements of this Annex.
Regulation 9 Issue or endorsement of Certificate
An International Pollution Prevention Certificate for the Carriage of Noxious Liquid Substances in Bulk shall be issued, after an initial or renewal survey to any ship intended to carry noxious liquid substances in bulk and which is engaged in voyages to ports or terminals under the jurisdiction of other Parties to the Convention.
Such Certificate shall be issued or endorsed either by the Administration or by any person or organization duly authorized by it. In every case, the Administration assumes full responsibility for the Certificate.
Regulation 10 Duration and validity of Certificate
An International Pollution Prevention Certificate for the Carriage of Noxious Liquid Substances in Bulk shall be issued for a period specified by the Administration which shall not exceed 5 years.
Regulation 11 Design, construction, equipment and operations
The design, construction, equipment and operation of ships certified to carry noxious liquid substances in bulk shall be in compliance with the provisions identified in chapter 17 of the International Bulk Chemical Code, to minimize the uncontrolled discharge into the sea of such substances.
Regulation 12 Pumping, piping, unloading arrangements and slop tanks
Every ship constructed on or after 1 January 2007 shall be provided with a pumping and piping arrangement to ensure that each tank certified for the carriage of substances in category X, Y or Z does not retain a quantity of residue in excess of 75 liters in the tank and its associated piping.
Ships certified to carry substances of category X, Y or Z shall have an underwater discharge outlet (or outlets).
The underwater discharge outlet (or outlets) shall be located within the cargo area in the vicinity of the turn of the bilge and shall be so arranged as to avoid the re-intake of residue/water mixtures by the ship’s seawater intakes.
Regulation 13 Control of discharges of residues of noxious liquid substances
The discharge into the sea of residues of substances assigned to category X, Y or Z or ballast water, tank washings or other mixtures containing such substances shall be prohibited unless such discharges are made in full compliance with the applicable operational requirements contained in this Annex.
Before any prewash or discharge procedure is carried out in accordance with this regulation, the relevant tank shall be emptied to the maximum extent
Discharge standards
- 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 through the underwater discharge outlet(s) not exceeding the maximum rate for which the underwater discharge outlet(s) is (are) designed
- The discharge is made at a distance of not less than 12 nautical miles from the nearest land in a depth of water of not less than 25 metres
Regulation 14 Procedures and Arrangements Manual
Every ship certified to carry substances of category X, Y or Z shall have on board a Manual approved by the Administration. The Manual shall have a standard format in compliance with this Annex. In the case of a ship engaged in international voyages on which the language used is not English, French or Spanish, the text shall include a translation into one of these languages.
The main purpose of the Manual is to identify for the ship’s officers the physical arrangements and all the operational procedures with respect to cargo handling, tank cleaning, slops handling and cargo tank ballasting and deballasting which must be followed in order to comply with the requirements of this Annex.
Regulation 15 Cargo Record Book
- Every ship to which this Annex applies shall be provided with a Cargo Record Book, whether as part of the ship’s official log-book or otherwise, in the form specified to this Annex.
- In the event of an accidental discharge of a noxious liquid substance or a mixture containing such a substance or a discharge, an entry shall be made in the Cargo Record Book stating the circumstances of, and the reason for, the discharge.
- Each entry shall be signed by the officer or officers in charge of the operation concerned and each page shall be signed by the master of the ship
- The Cargo Record Book shall be kept in such a place as to be readily available for inspection. It shall be retained for a period of three years after the last entry has been made.
- The competent authority of the Government of a Party may inspect the Cargo Record Book on board any ship to which this Annex applies while the ship is in its port, and may make a copy of any entry in that book and may require the master of the ship to certify that the copy is a true copy of such entry.
Regulation 17 Shipboard marine pollution emergency plan for noxious liquid substances
Every ship of 150 gross tonnages and above certified to carry noxious liquid substances in bulk shall carry on board a shipboard marine pollution emergency plan for noxious liquid substances approved by the Administration.
Such a plan shall be based on the Guidelines developed by the Organization [Resolution MEPC.138(53)] and written in a working language or languages understood by the master and officers. The plan shall consist at least of:
- The procedure to be followed by the master or other persons having charge of the ship to report a noxious liquid substances pollution incident.
- The list of authorities or persons to be contacted in the event of a noxious liquid substances pollution incident
- A detailed description of the action to be taken immediately by persons on board to reduce or control the discharge of noxious liquid substances following the incident.
