Downey, CA Environmental Rules: Gas Leaf Blower Ban (2026)

(a) (1) By July 1, 2022, the state board shall, consistent with federal law, adopt cost-effective and technologically feasible regulations to prohibit engine exhaust and evaporative emissions from new small off-road engines, as defined by the state board. Those regulations shall apply to engines produced on or after January 1, 2024, or as soon as the state board determines is feasible, whichever is later. (2) In determining technological feasibility pursuant to paragraph (1), the state board shall consider all of the following: (A) Emissions from small off-road engines in the state. (B) Expected timelines for zero-emission small off-road equipment development. (C) Increased demand for electricity from added charging requirements for more zero-emission small off-road equipment. (D) Use cases of both commercial and residential lawn and garden users. (E) Expected availability of zero-emission gener[ators]. Small off-road engines (SORE), which are used primarily in lawn and garden equipment, emit high levels of air pollutants, including oxides of nitrogen (NOx), reactive organic gases (ROG), and particulate matter (PM). In 2020, California daily NOx and ROG emissions from SORE were higher than emissions from light-duty passenger cars. SORE emitted an average of 16.8 tons per day of NOx and 125 tons per day of ROG.
