Summary
Downey regulates leaf blower noise under its general noise ordinance. Gas-powered leaf blowers must comply with the 85 dBA construction equipment limit and operate only during permitted hours.
Existing law imposes various limitations on the emissions of air contaminants for the control of air pollution from vehicular and nonvehicular sources. Existing law assigns the responsibility for controlling vehicular sources of air pollution to the State Air Resources Board. This bill would require the state board, by July 1, 2022, consistent with federal law, to 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. The bill would require the state board to identify and, to the extent feasible, make available funding for commercial rebates or similar incentive funding
