Appendix A
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).
