The Environmental Protection Agency (EPA) has changed the deadline for promulgation of the second set of air emission standards for large marine diesel engines
(those at or above 30 liters per cylinder) from April 27, 2007 to December 17, 2009. The reason for the delay is to allow for further negotiations of international standards at IMO. The delay will also provide time for consideration of the state of technology for deeper emission reductions.
