The provisions of this section apply separately for calculating emission credits for NOX or PM.
Emission credits = (Std-FEL) * (1.341) * (UL) * (Production) * (Fp) * (10-3 kW-Mg/MW-g).
Where:
Std = the applicable NOX or PM emission standard in g/bhp-hr (except that Std = previous FEL in g/bhp-hr for locomotives that were certified under this part to an FEL other than the standard during the previous useful life).
FEL = the family emission limit for the engine family in g/bhp-hr.
UL = the sales-weighted average useful life in megawatt-hours (or the subset of the engine family for which credits are being calculated), as specified in the application for certification.
Production = the number of locomotives participating in the averaging, banking, and trading program within the given engine family during the calendar year (or the number of locomotives in the subset of the engine family for which credits are being calculated). Quarterly production projections are used for initial certification. Actual applicable production/sales volumes are used for end-of-year compliance determination.
Fp = the proration factor as determined in paragraph (d) of this section.
