EPA has adopted exhaust emission standards for marine diesel engines installed in a variety of marine vessels ranging in size and application from small recreational vessels to tugboats and large ocean-going vessels.

These domestic emission standards apply for engines installed on U.S. vessels.

Additional international requirements may apply for engines installed on U.S. vessels that operate in foreign ports and waters and for foreign vessels.
