New Source Performance Standards for Stationary Spark Ignition Internal Combustion Engines
Rule Summary
Stationary engines use pistons that alternately move back and forth to convert preassue inro rotating motion. They are used in a variety of applications from generating electricity to powering pumps and compressors in power and manufacturing plants. They are also used in the event of an emergency such as fire or flood.
A spark ignition (SI) engine, or gasoline engine, is a type of engine in which the fuel-air mixture in the combustion chamber is ignited by a spark from a spark plug.
The key pollutants EPA regulates from these sources includes nitrogen oxides (NOx), carbon monoxide (CO), and volatile organic compounds (VOC).
The New Source Performance Standards (NSPS) for Stationary Spark Ignition Internal Combustion Engines is outlined in the Code of Federal Regulations under 40 CFR Part 60 Subpart JJJJ.
