Stationary Spark Ignition Internal Combustion Engines (SI ICE) -  Subpart JJJJ

Applicability: eCFR Subpart JJJJ [ecfr.gov]

This subpart applies to:
  1. Manufacturers of SI ICE with a maximum engine power ≤ 19 kW (25 HP) that are manufactured on or after July 1, 2008.
  2. Manufacturers of stationary SI ICE with a maximum engine power >19 kW (25 HP) that are gasoline fueled or that are rich burn engines fueled by liquified petroleum gas (LPG), where the date of manufacture is:
    1. On or after July 1, 2008; or
    2. On or after January 2009, for emergency engines.
  3. Manufacturers of stationary SI ICE with a maximum engine power >19 kW (25 HP) that are not gasoline fueled or that are not rich burn engines fueled by LPG, where the manufacturer participates in the voluntary manufacturer certification program that is part of this subpart where the date of manufacture is:
    1. On or after July 1, 2007: engines with a maximum power of ≥ 500 HP, except lean burn engines with a maximum power of 500 ≤ HP < 1,350;
    2. On or after Jan 1, 2008: lean burn engines with a maximum power of 500 ≤ HP < 1,350;
    3. On or after July 1, 2008: engines with a maximum power of < 500 HP; or
    4. On or after Jan 1, 2009: emergency engines
  4. Owners or operators of SI ICE that commenced construction after June 12, 2006, where the SI ICE are manufactured:
    1. On or after July 1, 2007: engines with a maximum power of ≥ 500 HP, except lean burn engines with a maximum power of 500 ≤ HP < 1,350;
    2. On or after Jan 1, 2008: lean burn engines with a maximum power of 500 ≤ HP < 1,350;
    3. On or after July 1, 2008: engines with a maximum power of < 500 HP; or
    4. On or after Jan 1, 2009: emergency engines with a maximum power of > 19 kW (25 HP).
  5. Owners or operators that modify or reconstruct their SI ICE after June 12, 2006.
The date that construction commences is the date the engine is ordered by the owner or operator. The installation date is the date the engine is installed at the plant site.

Alcohol-based fuels (i.e. ethanol, methanol) have the same requirements as gasoline fuel.

Not subject to this subpart:
  1. Any CI ICE being tested at a CI ICE test cell/stand.
  2. Any CI ICE used for national security (see fact sheet below).
  3. Temporary replacement engines that are certified nonroad engines and are on-site for less than 1 year.
