Minimum number = [(T-O1-F)/(T-F)-0.05] * P
Where:
T = The total number of 2008-2010 model year engines at or above 37 kW and below 56 kW that you use in equipment you produce.
O1 = The number of engines from the 2008-2010 model years certified under Option #1 of Table 3 of § 1039.102 that you use in equipment you produce.
F = The number of 2008-2010 model year engines at or above 37 kW and below 56 kW that you use in equipment you produce under the flexibility provisions of § 1039.625 .
P = The total number of 2012 model year engines at or above 37 kW and below 56 kW that you use in equipment you produce.

Table 2 of § 1039.104 -Alternate FEL Caps
Maximum engine power | PM FEL cap, g/kW-hr | Model years for the alternate PM FEL cap | NOX FEL cap, g/kW-hra | Model years for the alternate NOX FEL cap |
19 [LESS THAN EQUAL TO]kW [LESS THAN]56 | 0.30 | b 2012-2015 | ||
56 [LESS THAN EQUAL TO]kW [LESS THAN]130c | 0.30 | 2012-2015 | 3.8 | d 2012-2015 |
130 [LESS THAN EQUAL TO]kW [LESS THAN EQUAL TO]560 | 0.20 | 2011-2014 | 3.8 | e 2011-2014 |
kW [GREATER THAN]560f | 0.10 | 2015-2018 | 3.5 | 2015-2018 |
a The FEL cap for engines demonstrating compliance with a NOX + NMHC standard is equal to the previously applicable NOX + NMHC standard specified in appendix I of this part (generally the Tier 3 standards).
b For manufacturers certifying engines under Option #1 of Table 3 of § 1039.102 , these alternate FEL caps apply to all 19-56 kW engines for model years from 2013 through 2016 instead of the years indicated in this table. For manufacturers certifying engines under Option #2 of Table 3 of § 1039.102 , these alternate FEL caps do not apply to 19-37 kW engines except in model years 2013 to 2015.
c For engines below 75 kW, the FEL caps are 0.40 g/kW-hr for PM emissions and 4.4 g/kW-hr for NOX emissions.
d For manufacturers certifying engines in this power category using a percentage phase-in/phase-out approach instead of the alternate NOX standards of § 1039.102(e)(1) , the alternate NOX FEL cap in the table applies only in the 2014-2015 model years if certifying under § 1039.102(d)(1) , and only in the 2015 model year if certifying under § 1039.102(d)(2) .
e For manufacturers certifying engines in this power category using the percentage phase-in/phase-out approach instead of the alternate NOX standard of § 1039.102(e)(2) , the alternate NOX FEL cap in the table applies only for the 2014 model year.
f For engines above 560 kW, the provision for alternate NOX FEL caps is limited to generator-set engines.
