PART 1039_CONTROL OF EMISSIONS FROM NEW AND IN-USE NONROAD 

COMPRESSION-IGNITION ENGINES--Table of Contents

 

       Subpart H_Averaging, Banking, and Trading for Certification

 

Sec.  1039.705  How do I generate and calculate emission credits?



    The provisions of this section apply separately for calculating 

emission credits for NOX, NOX+NMHC, or PM.

    (a) Calculate positive emission credits for an engine family that 

has an FEL below the otherwise applicable standard. Calculate negative 

emission credits for an engine family that has an FEL above the 

otherwise applicable standard.

    (b) For each participating engine family, calculate positive or 

negative emission credits relative to the otherwise applicable emission 

standard. Round calculated emission credits to the nearest kilogram 

(kg), using consistent units throughout the following equation:



Emission credits (kg) = (Std - FEL) x (Volume) x (AvgPR) x (UL) x 

    (10-3)



Where:



Std = the emission standard, in grams per kilowatt-hour, that applies 

under subpart B of this part for engines not participating in the ABT 

program of this subpart (the ``otherwise applicable standard'').

FEL = the family emission limit for the engine family, in grams per 

kilowatt-hour.

Volume = the number of engines eligible to participate in the averaging, 

banking, and trading program within the given engine family during the 

model year, as described in paragraph (c) of this section.

AvgPR = the average maximum engine power of all the engine 

configurations within an engine family, calculated on a sales-weighted 

basis, in kilowatts.



[[Page 528]]



UL = the useful life for the given engine family, in hours.



    (c) In your application for certification, base your showing of 

compliance on projected production volumes for engines whose point of 

first retail sale is in the United States. As described in Sec.  

1039.730, compliance with the requirements of this subpart is determined 

at the end of the model year based on actual production volumes for 

engines whose point of first retail sale is in the United States. Do not 

include any of the following engines to calculate emission credits:

    (1) Engines exempted under subpart G of this part or under 40 CFR 

part 1068.

    (2) Exported engines.

    (3) Engines not subject to the requirements of this part, such as 

those excluded under Sec.  1039.5.

    (4) [Reserved]

    (5) Any other engines, where we indicate elsewhere in this part 1039 

that they are not to be included in the calculations of this subpart.
