HI HB256

Requires waste-to-energy facility owners and operators to comply with EPA emission standards under 40 CFR Part 60 as they existed on December 31, 2024, preventing any federal rollback of environmental protections

Applies to multiple EPA subparts covering municipal waste combustors of various sizes and construction dates, including general provisions, emissions guidelines, and performance standards

Allows stricter emission limits to supersede the December 2024 baseline if imposed by updated federal regulations or state air pollution control permits issued by the Department of Health

Takes effect December 31, 2050, and sunsets on June 30, 2027 (note: the effective date appears to be a drafting anomaly as it occurs after the repeal date)
