                   TITLE 40--PROTECTION OF ENVIRONMENT
 
         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 89--CONTROL OF EMISSIONS FROM NEW AND IN-USE NONROAD COMPRESSION-IGNITION 
ENGINES--Table of Contents
 
          Subpart C--Averaging, Banking, and Trading Provisions
 
Sec. 89.202  Definitions.

    The definitions in subpart A of this part apply to this subpart. The 
following definitions also apply to this subpart:
    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.
