∗ – JJJJ applicable if the date that engine is ordered (or the engine was modified or reconstructed) after June 12, 2006 AND the manufacture date is after the listed date.
Engine <500 HP must perform an intial performance test within 8760 hours of startup to demonstrate compliance.
Engine ≥ 500 HP must perform an intial performace test within 8760 hours of startup to demonstrate compliance, and then every 8,760 hours or 3 years, whichever comes first.
For all engines,you must keep a maintenance plan and records of conducted maintenance and must, to the extent practicable, maintain and operate the engine in a manner consistent with good air pollution control practice for minimizing emissions.
Provided as a guide only. Reader should refer to 40 CFR 60, Subpart JJJJ for actual requirements.
