September 4, 2008, Final Rule: Control of Emissions of Air Pollution from New Nonroad Spark-Ignition Engines, Equipment, and Vessels

EPA has finalized a new emission control program to reduce hydrocarbon emissions from small spark-ignition engines by about 35 percent. The new exhaust emissions standards will take effect in 2011 or 2012, depending on the size of the engine. The final rule also includes new standards to reduce evaporative emissions from these fuel systems. These standards will reduce the harmful health effects of ozone and carbon monoxide from these engines.

This page provides consumer information, regulations, guidance, and compliance fee and certification data for ten categories of nonroad spark-ignition engines, ranging from lawn and garden equipment through airport service equipment. For the homeowner, there is information about maintaining a yard and lawn, while minimizing air pollution from spark-ignition engines. For additional information about our emission standards, see our Fact Sheet: Final Emission Standards for New Nonroad Spark-ignition Engines, Equipment, and Vessels | PDF Version (xx pp, xxK, EPA420-F-08-013).

I’m sure lawnmowers are a significant contributer to global warming cooling climate change. Thank baby Jesus the EPA is there to save us.
