What is the Nonroad SI Safety Study?
This technical study assesses the incremental impact on safety of applying the advanced emission control technology expected to meet the new emission standards that EPA is considering for particular subcategories of nonroad engines and equipment, focusing on the risk of fire and burn to consumers. The study will be part of the rulemaking record for the upcoming proposed standards and satisfies the provisions of section 205 of PL 109-54, which requires EPA to assess potential safety issues, including the risk of fire and burn to consumers, associated with the proposed emission standards for nonroad SI engines under 50 horsepower (hp).
