.1is prohibited except when the emission of nitrogen oxides (calculated as the total weighted emission of NOX) from the engine is within the following limits, where n = rated engine speed (crankshaft revolutions per minute):
.1 3.4 g/kWh when n is less than 130 rpm;
.2 9 ·n(–0.2) g/kWh when n is 130 or more but less than 2,000 rpm;
.3 2.0 g/kWh when n is 2,000 rpm or more;
when:
.2 that ship is constructed on or after 1 January 2016 and is operating in the North American Emission Control Area or the United States Caribbean Sea Emission Control Area;
when:
.3 that ship is operating in an emission control area designated for Tier III NOX control under paragraph 6 of this regulation, other than an emission control area described in paragraph 5.1.2 of this regulation, and is constructed on or after the date of adoption of such an emission control area, or a later date as may be specified in the amendment designating the NOX Tier III emission control area, whichever is later.
5.2 The standards set forth in paragraph 5.1.1 of this regulation shall not apply to:
.1 a marine diesel engine installed on a ship with a length (L), as defined in regulation 1.9 of Annex I to the present Convention, of less than 24 metres when it has been specifically designed, and is used solely, for recreational purposes; or
.2a marine diesel engine installed on a ship with a combined nameplate diesel engine propulsion power of less than 750 kW if it is demonstrated, to the satisfaction of the Administration, that the ship cannot comply with the standards set forth in paragraph 5.1.1 of this regulation because of design or construction limitations of the ship; or
.3 a marine diesel engine installed on a ship constructed prior to 1 January 2021 of less than 500 gross tonnage, with a length (L), as defined in regulation 1.19 of Annex I to the present convention, of 24 m or over when it has been specifically designed, and is used solely, for recreational purposes
