La Tier III è applicabile solo per l’area ECA degli USA e non per le altre aree ECA?
Confermiamo che attualmente il limite Tier III deve essere applicato solo nelle aree ECA degli USA.
La frase presente nel sito “As 1st January 2016 a marine diesel engine that is installed on a ship constructed on or after this date shall comply with the Tier III NOx standards if the ship is operating within ECAs or at least shall comply with Tier II NOx Standard if it is operating outside ECAs.” è stata sviluppata come indicato nell’AnnexVI al paragrafo 5.1.
Il “paragraph 6” citato nel 5.1 rimanda al regolamento di qualifica delle aree ECA presente nell’ “appendix III“ dello stesso Annex VI, il quale non indica le aree ECA.
Nella parte successiva del nostro articolo, abbiamo indicato le attuali aree ECA e per quali inquinanti queste sono designate:
“And what about ECAs? Emission Control Areas (ECAs) are sea areas in which stricter controls were established to minimize airborne emissions (SOx, NOx, ODS, VOC) from ships as defined by Annex VI of the 1997 MARPOL Protocol which came into effect in May 2005. As of 2011 existing ECAs include the Baltic Sea(SOx, adopted 1997; enforced 2005) and the North Sea (SOx, 2005/2006 adopted July 2005; enforced 2006), the North American ECA, including most of US and Canadian coast (NOx & SOx, 2010/2012) and the US Caribbean ECA, including Puerto Rico and the US Virgin Islands (NOx & SOx, 2011/2014)”.
Questo è confermato dal seguente articolo IMO:
Resta comunque in vigore il limite Tier II per tutte le restanti aree.
