 CAA vapor control and recovery standards for cleaning fuel tanks and conducting other operations in regulated port areas and emissions standards for so-called “ Category 3” marine diesel engines operating in U. S. waters. On December 22, 2009, the EPA adopted final emission standards for Category 3 marine diesel engines equivalent to those adopted in the amendments to Annex VI to MARPOL. As a result, the most stringent engine emissions and marine fuel sulfur requirements of Annex VI will apply to all vessels regardless of flag entering U. S. ports or operating in U. S. waters, and to all U. S. flagged vessels regardless of location. The emission standards apply in two stages: near-term standards for newly-built engines, which have applied since the beginning of 2011, and long-term standards requiring an 80% reduction in NOx by 2030, which has applied from the beginning of 2016, requiring the use of emission control technology. In January 2021, the EPA expanded the availability of a proven, modern inspection method for finding and correcting air pollution leaks at large liquid storage tanks. These amendments allow owner/ operators of certain large tanks known as Volatile Organic Liquid Storage Vessels to conduct less cumbersome "in service" inspections of the tanks, without emptying and degassing the storage tank.

  IMO Emission Control Areas.  

As of 1 January 2020, all vessels subject to MARPOL operating in ECAs (defined above) must use fuel with a sulfur content of 0.10%. Those areas comprise: (1) the Baltic Sea area, (2) the North Sea area, (3) the North American Emission Control Area, (4) the United States Caribbean Sea Emission Control area, and (5) the Mediterranean Sea Emission Control Area as further defined in MARPOL (effective 1 May 2025).

Pursuant to MEPC 82 (held in December 2024): (6) the Canadian Artic Emission Control Area and (7) the Norwegian Sea (as each defined in MARPOL) will also be included as ECAs, from 1 March 2026. To comply with said limits, MARPOL Annex VI allows the vessel's Administration (aka flag state) to allow the use of any " fitting, material, appliance or apparatus to be fitted in a ship …" so long as at least as effective in terms of emissions reductions as those requirements, including EGCS (aka scrubbers). The 2021 EGCS
