APPENDIX 5 - RESOLUTION MEPC.115 (51) - Adopted on April 1, 2004

Regulation 11: Wastewater discharge

1 Subject to the provisions of rule 3 of this Annex, the discharge of wastewater into the sea is prohibited, except in the following cases.

1 the ship discharges crushed and disinfected sewage by means of a system approved by the Administration in accordance with regulation 9.1.2 of this annex at a distance of more than 3 nautical miles from the nearest land, or sewage which is not crushed or disinfected at a distance of more than 12 nautical miles from the nearest land, it being understood that in any case the sewage which has been stored in the holding tanks should not be discarded instantly but at a moderate rate when the vessel is underway and going at a speed of at least 4 knots; the discharge rate must be approved by the administration on the basis of standards developed by the Organization; or

.2 the ship operates an approved sewage treatment plant which has been certified by the administration as meeting the operating requirements referred to in regulation 9.1.1 of this annex, and

BLUE PAVILION

“The marina should have an environmental policy and plan. The plan should include references to water management, waste and energy use, health and safety issues, and use of environmentally friendly products whenever possible ".

"Bilge water pumping facilities must be available in the marina ... The facilities must be easily accessible to all potential users."

"Toilet tank waste reception facilities should be present in the marina. Toilet tank waste reception facilities may consist of a permanent toilet pumping station, a mobile toilet pumping facility. or a sludge pumping van ... The facilities must be easily accessible to boat owners ".

"The water in the marina must be visually clean, free from any traces of pollution, for example oil, rubbish, sewage or other traces of pollution."

THE DIFFERENT TYPES OF POLLUTION REFERRED TO IN THE REGULATION

OIL POLLUTION

Small and medium-scale pollution caused by leaks of refined petroleum products (eg bilge water, refueling). Oil pollution is the most visible because it causes an oil reflection on the water which reduces the penetration of light and the oxygenation of the water.

SOLID WASTE

Solid waste represents a direct risk for flora and fauna. The impact is particularly harmful when they are not biodegradable.

For example, fish, birds and marine mammals die from the ingestion of plastic objects.

WASTE

Wastewater, whatever its origin, can have many negative effects:

  • Coloration of the water due to suspended solids, resulting in a decrease in

light penetration

  • Eutrophication of water by nutrients, causing accelerated growth

algae and resulting in reduced oxygen levels in the water

  • Introduction of pathogenic organisms that can transmit diseases to

the man

WATER FROM THE DUMP

Bilge water is found on almost all ships. Depending on the design and function of the vessel, bilge water may contain water, oil, detergents, solvents, chemicals, particles and other materials. Some of these substances can be persistent organic pollutants.

SECURITY / FIRE FIGHTING

The port is responsible for the safety of its users, and must therefore be prepared for a number of actions such as

  • Rescue of a person who has fallen into the water

  • Fight against the fire

  • First aid
