Reply #20: No more than the thousands of other boats and ships that litter the sea floor.

My understanding is that the ship went down pretty far offshore, so they're probably not that concerned about spillage. Once you get out a certain distance, the sea itself will break any fuel slick up before it reaches land. Fuel oil spills are fairly small in the grand scheme of things, and they tend to leak slowly which gives the ocean plenty of time to break it down before it does any real damage.

Bunker oil spills can be a concern when they happen in a closed bay, such as the spill in SF a few weeks ago, or when they happen close to shore, where the ocean cannot break the oil up before it reaches land, but it doesn't sound like that's the case here.
