| 摘要： | On January 1 of this year, the final version of the California Harbor Craft emissions rule issued by the California Air Resources Board (CARB) took effect. It gave operators of harbor craft, including commercial tugboats, tow-boats and ferries until December 2024 to have all their boats operated with Tier 4 engines outfitted with diesel par-ticulate filters (DPFs), attachments designed to burn particulate matter (soot) before it exits into the atmosphere. (Fishing boats are exempt.) The problem is DPFs for marine diesel engines don't exist, and there is no prospect of their being introduced anytime soon. Even if they did exist, the rule's aggressive timeline doesn't give enough time for the Coast Guard and maritime class societies to examine them to make sure they are safe to operate. When a certified marine engine is modified, its safety, efficiency, operability and even insurability can be affected. |
