(a) A manufacturer may use averaging to offset an emission exceedance of a nonroad engine family caused by an FEL above the applicable emission standard. Credits used in averaging may be obtained from credits generated by another engine family in the same model year, credits banked in the three previous model years, or credits obtained through trading.

(b) Credits scheduled to expire in the earliest model year must be used first, before using other available credits.
