Family emission limit (FEL)

Family emission limit (FEL) means one of the following:
(1) For NOX emissions, family emission limit means a NOX emission level declared by the manufacturer to serve in place of an otherwise applicable emission standard under the ABT program in subpart H of this part. The FEL serves as the emission standard for the engine family with respect to all required testing.
(2) For greenhouse gas standards, family emission limit means an emission level that serves as the standard that applies for testing individual certified engines. The CO2 FEL is equal to the CO2 FCL multiplied by 1.03 and rounded to the same number of decimal places as the standard.
