Phase 2 Emission Standards for New Nonroad Spark-Ignition Handheld Engines At or Below 19 Kilowatts: Summary and Analysis of Comments.

摘要

On January 27, 1998, the US Environmental Protection Agency (EPA) published in the Federal Register a Notice of Proposed Rulemaking (NPRM) for emission standards for new nonroad spark ignition (SI) engines at or below 19 kilowatts (kW). The purpose of the small SI engines NPRM, as required by section 213(a)(3) of the amended Clean Air Act, is to regulate emissions from a category of new nonroad engines and vehicles that, in EPA's judgment, cause or contribute to air pollution in areas that failed to attain the National Ambient Air Quality Standards (NAAQS) for ozone or carbon monoxide.
