§ 1036.625 In-use compliance with CO2 family emission limits (FELs).

Section 1036.225 describes how to change the FEL for an engine family during the model year. This section, which describes how you may ask us to increase an engine family's CO₂ FEL after the end of the model year, is intended to address circumstances in which it is in the public interest to apply a higher in-use CO₂ FEL based on forfeiting an appropriate number of emission credits. For example, this may be appropriate where we determine that recalling vehicles would not significantly reduce in-use emissions. We will generally not allow this option where we determine the credits being forfeited would likely have expired.
