         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 91--CONTROL OF EMISSIONS FROM MARINE SPARK-IGNITION ENGINES--Table of 
Contents
 
          Subpart C--Averaging, Banking, and Trading Provisions
 
Sec. 91.202  Definitions.

    The definitions in subpart A of this part apply to this subpart. The 
following definitions also apply to this subpart:
    Averaging for marine SI engines means the exchange of emission 
credits among engine families within a given manufacturer's product 
line.
    Banking means the retention of marine SI engine emission credits by 
the manufacturer generating the emission credits for use in future model 
year averaging or trading as permitted by these regulations.
    Eligible sales means marine SI engines sold for purposes of being 
used in the United States and include any engine introduced into 
commerce in the U.S. to be sold for use in the U.S.
    Emission credits represent the amount of emission reduction or 
exceedance, by a marine SI engine family, below or above the applicable 
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.
    Point of first retail sale means the point at which the engine is 
first sold directly to an end user. Generally, this point is the retail 
boat or engine dealer. If the engine is sold first to a boat or vessel 
manufacturer for installation

[[Page 312]]

in a boat or vessel, the boat or vessel manufacturer may be the point of 
first retail sale if the boat or vessel manufacturer can determine if 
the engine is or is not exported once they have sold the boat or vessel. 
If the boat or vessel manufacturer cannot determine if the engine is or 
is not exported once they have sold the boat or vessel, the engine is 
presumed to not be exported, unless the engine manufacturer can 
demonstrate otherwise. Engine manufacturers must include engines in 
their average if the engine is exported and subsequently imported into 
the United States installed in a boat or vessel and introduced into 
United States commerce.
    Trading means the exchange of marine engine emission credits between 
manufacturers.
