HI HB1546

Requires the Department of Health to adopt regulations prohibiting engine exhaust and evaporative emissions from new small off-road engines, applicable to engines produced on or after January 1, 2024, or as soon as feasible.

Department must consider emissions levels in Hawaii, zero-emission equipment development timelines, electricity demand impacts, and commercial and residential user needs when determining technological feasibility of regulations.

Establishes that one hour of commercial leaf blower operation emits as much reactive organic gases and oxides of nitrogen as driving 1,100 miles in a new passenger vehicle, contributing to ozone formation, air quality degradation, and climate warming.

Department of Health must submit a report to the legislature by December 31, 2023, with recommendations for funding commercial rebates or incentive programs to support transition to zero-emission small off-road equipment.

Aims to achieve 100 percent zero emissions from off-road equipment in Hawaii by 2030, where feasible and cost-effective, consistent with federal law.
