aOwners and operators of stationary non-certified SI engines may choose to comply with the emission standards in units of either g/HP-hr or ppmvd at 15 percent O2.

bOwners and operators of new or reconstructed non-emergency lean burn SI stationary engines with a site rating of greater than or equal to 250 brake HP located at a major source that are meeting the requirements of 40 CFR part 63, subpart ZZZZ, Table 2a do not have to comply with the CO emission standards of Table 1 of this subpart.

cThe emission standards applicable to emergency engines between 25 HP and 130 HP are in terms of NOX + HC.

dFor purposes of this subpart, when calculating emissions of volatile organic compounds, emissions of formaldehyde should not be included.
