New Source Performance Standards for Stationary Compression Ignition Internal Combustion Engines (40 CFR Part 60 Subpart IIII) Applicability to natural gas industry A compression ignition (CI) engine, or diesel engine, is a type of engine in which the fuel injected into the combustion chamber is ignited by a heat resulting from the compression of gases inside the cylinder. Stationary engines are used in a variety of applications from generating electricity to powering pumps and compressors. They are also used in the event of an emergency such as fire or flood. You are subject to this rule if you are an owner or operator of a regulated SI internal combustion engine that was manufactured after July 1, 2008. Compliance information Owners and operators of CI engines must meet standards that vary depending on whether the engine is a pre-2007 model or 2007 model or later. Also, the standards vary depending on whether the engine is an emergency or non-emergency engine. The emission standards are found in §60.4204 and §60.4205. US EPA.
