# §1051.705. How do I average emission levels?

- (a) As specified in subpart B of this part, certify each vehicle to an FEL, subject to the FEL caps in subpart B of this part.
- (b) Calculate a preliminary average emission level according to [§ 1051.720](/cfr/40/1051.720.md) for each averaging set using projected U.S.-directed production volumes from your application for certification, excluding vehicles described in [§ 1051.701(d)(4)](/cfr/40/1051.701.md?p=d-4).
- (c) After the end of your model year, calculate a final average emission level according to [§ 1051.720](/cfr/40/1051.720.md) for each type of recreational vehicle or engine you manufacture or import. Use actual U.S.-directed production volumes, excluding vehicles described in [§ 1051.701(d)(4)](/cfr/40/1051.701.md?p=d-4).
- (d) If your preliminary average emission level is below the allowable average standard, see [§ 1051.710](/cfr/40/1051.710.md) for information about generating and banking emission credits. These credits will be considered reserved until we verify them in reviewing the end-of-year report.
- (e) If your average emission level is above the allowable average standard, you must obtain enough emission credits to offset the deficit by the due date for the final report required in [§ 1051.730](/cfr/40/1051.730.md). The emission credits used to address the deficit may come from emission credits you have banked or from emission credits you obtain through trading.
