Sec.  89.202  Definitions.



    The definitions in subpart A of this part apply to this subpart. The 

following definitions also apply to this subpart:



[[Page 69]]



    Averaging for nonroad engines means the exchange of emission credits 

among engine families within a given manufacturer's product line.

    Banking means the retention of nonroad engine emission credits by 

the manufacturer generating the emission credits for use in future model 

year averaging or trading as permitted by these regulations.

    Emission credits represent the amount of emission reduction or 

exceedance, by a nonroad engine family, below or above the emission 

standard, respectively. Emission reductions below the standard are 

considered as ``positive credits,'' while emission exceedances above the 

standard are considered as ``negative credits.'' In addition, 

``projected credits'' refer to emission credits based on the projected 

applicable production/sales volume of the engine family. ``Reserved 

credits'' are emission credits generated within a model year waiting to 

be reported to EPA at the end of the model year. ``Actual credits'' 

refer to emission credits based on actual applicable production/sales 

volume as contained in the end-of-year reports submitted to EPA. Some or 

all of these credits may be revoked if EPA review of the end-of-year 

reports or any subsequent audit action(s) uncovers problems or errors.

    Trading means the exchange of nonroad engine emission credits 

between manufacturers.
