Control of Emissions from Marine Spark Ignition and Small SI Engines, Vessels, & Equipment, Draft Regulatory Impact Analysis.
The Environmental Protection Agency is proposing requirements to reduce emissions of hydrocarbon (HC) and oxides of nitrogen (NOx) from nonroad small park ignited engines below 19kW ("Small SI engines") and marine spark ignited engines ("Marine SI engines"). This proposed rule includes exhaust and evaporative emission standards for these engines as well as related gasoline fuel tanks and fuel lines.
