https:/crsreports.congress.gov March 14, 2018New Residential Wood Heaters: Potential Impacts from Delaying Federal Emission StandardsOn March 7, 2018, the House passed H.R. 1917, which would, among other things, delay the effective date of federal emission standards for new residential wood heaters promulgated by the U.S. Environmental Protection Agency (EPA) in 2015. House and Senate hearings in late 2017 highlighted concerns about inadequate time to demonstrate compliance with emission standards by the 2020 deadline. Others have expressed concerns about the air quality impacts of delaying the 2020 deadline. The legislation also raises questions about state- and local-level impacts. For example, one witness testified that a delay could negatively affect jurisdictions in which wood smoke emissions already make it difficult to meet federal air quality standards. This In Focus explores how the legislation might interact with state- and local-level emission standards.
