Regulations for Emissions from Vehicles and Engines

Direct Final Rule for Amendments to the Phase 2 Requirements for Spark-Ignition Nonroad Engines at or Below 19 Kilowatts

Rule Summary

EPA adopted Phase 2 requirements for spark-ignition nonroad handheld engines at or below 19 kilowatts in April 2000. The Phase 2 requirements are being phased-in between 2002 and 2007. Based on initial experience with the Phase 2 program for handheld engines, we are adopting several amendments intended to provide additional compliance flexibility to engine manufacturers to smooth the transition to the Phase 2 requirements. The amendments contain two revisions intended to increase flexibility in the averaging, banking, and trading program as it applies to handheld engines.
