§ 89.205-96 - Banking.

(a) A manufacturer of a nonroad engine family with an FEL below the applicable standard for a given model year may bank credits in that model year for use in averaging and trading in the following three model years. Credits not withdrawn within the three model years after they are banked are forfeited.

(b) A manufacturer of a nonroad engine family may bank credits up to one calendar year prior to the effective date of mandatory certification. Such engines must meet the requirements of subparts A, B, D, E, F, G, H, I, J, and K of this part.

(c) A manufacturer may bank actual credits only after the end of the model year and after EPA has reviewed the manufacturer's end-of-year reports. During the model year and before submittal of the end-of-year report, credits originally designated in the certification process for banking will be considered reserved and may be redesignated for trading or averaging in the end-of-year report and final report.

(d) Credits declared for banking from the previous model year that have not been reviewed by EPA may be used in averaging or trading transactions. However, such credits may be revoked at a later time following EPA review of the end-of-year report or any subsequent audit actions.
