A new regulation aimed at reducing the discharge of sewage along the Norwegian coast has now been sent out on the right ring. The goal is to have the new rules in place by March 1, 2020.
On behalf of the Ministry of Climate and Environment, the Norwegian Maritime Directorate has prepared a proposal for new regulations for the discharge of sewage, which has now been sent out on the right.
The purpose is to prevent the discharge of sewage and contribute to less sewage discharge along the Norwegian coast, especially in inland waters with less electricity and less water exchange
The potential for sewage discharges is great, and the proposal will entail a monthly reduction of sewage emissions and help to protect the environment and health, says Bjørn E. Pedersen, Department Director of the Norwegian Maritime Directorate.
In Norwegian waters, emission requirements are less stringent than those laid down in the international regulations in MARPOL Annex IV, which say that the limit for sewage emissions is at 12 nautical miles, ie 22 224 meters from land. Furthermore, it is a requirement in MARPOL Annex IV that all vessels covered by the regulations must be equipped with sewage treatment plants, grinding / disinfecting plants and / or collection tanks. For painted and disinfected sewers, the boundary is at three nautical miles.
In Norway, impure sewage can be discharged 300 meters from land along large parts of the coast. This is due to the fact that many municipalities lacked sewage treatment plants when the regulations were introduced, in addition to generally good circulation in the water bodies along the coast.
In Norway, the rules in MARPOL Appendix IV apply only to ships in foreign trade on the lines from Lindesnes to the Swedish border. One now proposes to make emission requirements in MARPOL Annex IV applicable both to ships in international and domestic shipping, throughout the Norwegian waters
