The Bonn agreement is a European environmental agreement. 1. In the absence of agreement on the financial arrangements governing pollution control measures by parties that could be concluded on a bilateral or multilateral basis or in joint action to combat pollution, the parties bear the costs of their respective pollution control measures covered in paragraphs (a) or (b): the agreement was revised in 1983 to include the European Union and 2001 to allow Ireland to join. 1. The contracting parties provide for the fulfilment of the secretarial tasks relating to this agreement, taking into account existing arrangements under other international agreements relating to the prevention of marine pollution in the same region as this agreement. A contracting party that needs assistance in the fight against pollution or the likely occurrence of pollution at sea or on its coast may seek assistance from other contracting parties. Contracting parties requesting assistance determine the type of assistance they need. Contracting parties who are invited to assist under this section do everything in their power to provide the assistance available to them, particularly in the case of pollution from pollutants other than hydrocarbons, to take into account the technological means at their disposal. BAOAC was developed on the basis of a series of scientific experiments and studies within the framework of the Bonn Agreement. The method has been specially designed for aerial surveillance and the use of trained operators to detect and assess oil pollution at sea by an aircraft or helicopter. Based on a visual observation of oil pollution, the method can only be used during the day and during periods of good visibility.

Estimates of the volume of an oil spill at sea are not possible from a floating platform (or dock in a port). However, floating units can make approximate estimates of certain stages of the BAOAC and assess the severity of a slick visible from the water. Therefore, certain elements of the BAOAC method can (as far as possible) be used wisely from a floating platform, always taking into account the uncertainties necessarily associated in this case. Code one. „Sheen“ for all oil layers 0.04 to 0.3 m thick, the sunlight being more reflected by oil than by surrounding water. In particular, codes 4 and 5 (along with real oil paintings) contain considerable amounts of oil on a small area and are therefore, in most cases, considered slicks that can be fought at sea. The other codes for thinner oil layers, which often cover the largest areas of an oil spill, contain too little oil to be a reasonable prospect, even if dispersants are used. RR 2004 report: Comparison of three diesel samples 3. The contracting parties establish a standard form for the declaration of pollution in accordance with paragraph 1. 3. The termination takes effect one year after it is received by the custodian government. 2.

These States and the European Economic Community may become parties to this agreement, either through the signing of ratification, acceptance or approval, or by signing, subject to ratification, acceptance or approval, followed by ratification, acceptance or approval. This agreement applies where the likely presence or presence of hydrocarbons or other pollutants that pollute or threaten to pollute the sea in the North Sea region under Article 2 of this agreement poses a serious and imminent threat to the shoreline or related interests of one or more of the contracting parties.
