Rule Summary

EPA is finalizing technical corrections to the national diesel fuel regulations that will allow fuel suppliers to distribute distillate diesel fuel that complies with the 5,000 ppm international sulfur standard for ships instead of the fuel standards that otherwise apply to distillate diesel fuel in the United States. Fuel meeting the 5,000 ppm global sulfur cap may not be used inside of Emission Control Area (ECA) boundaries. These amendments will help facilitate smooth implementation of the 2020 global marine fuel standard.
