Regulations for Emissions from Small Equipment & Tools
EPA has adopted emission standards to control both exhaust and evaporative emissions from small spark-ignition engines. Phase 3 exhaust emissions standards took effect in 2011 or 2012, depending on the size of the engine. Evaporative emission standards address fuel permeation through fuel-system components in addition to fuel venting during engine operation.
