Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Use the values in this table unless the engine is an engine
					 certified to on-road standards.
Engines certified to on-road standards shall use the
					 standard to which the engine is certified. Engines certified to FEL and
					 flexibility engines shall still use the emission factors in the table
					 below.
Replacement engines produced per title 13, CCR, section
					 2423(j) shall use
					 the engine model year of the engine replaced. For an engine certified to an
					 emission standard lower than that shown in these tables for its model year, the
					 emission standard to which the engine is certified may be used, provided that
					 the certification Executive Order or certificate number is provided along with
					 the initial and annual reporting required by section
					 2449(g)(1) and
					 2449(g)(2).
If the model year of an engine is unknown because it is
					 missing a serial number, manufacturer's build code, and/or an engine family
					 number, and the engine manufacturer or authorized representative is unable to
					 determine the model year of the engine by examining the engine's build and
					 components, such an engine shall be treated as a 1969 model year engine. If a
					 manufacturer can bracket the model year of an engine (for example that an
					 engine was built between 1987 and 1994) by examining the engine's build and
					 components, the earliest date the engine could have been manufactured shall be
					 used as the model year of that engine (in the example, 1987).
