40 CFR 91.202 - Definitions.
The definitions in subpart A of this part apply to this subpart. The following definitions also apply to this subpart:
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.
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 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.
