Arizona's state-level GLB regulation is frozen in amber from a 2007–08 "Brown Cloud" PM-10 era. ARS § 49-457.01 (enacted via HB 2798, effective March 31, 2008) prohibits blowing landscape debris into public roadways, restricts leaf-blower use to stabilized surfaces, and requires triennial ADEQ-approved training for paid operators — applicable in counties ≥2M population (Maricopa) or EPA-designated PM-10 nonattainment (Pinal, Pima partial). It is a fugitive-dust statute, not a fuel-source rule. Executive Order 2007-03 (Governor Napolitano, February 2007) bans gas-powered landscape equipment on state property in Maricopa/Pima/Pinal counties (effective June 30, 2007); not rescinded but not actively audited. Maricopa County Rule P-25 (February 2008) requires Area A municipalities to prohibit government-fleet leaf-blower operation on High Pollution Advisory days except in vacuum mode. HB 2686 (2020, Ducey) preempts municipalities from "codes or ordinances that could have the effect of restricting a person's or entity's ability to use the services of a utility provider" — drafted in response to Berkeley CA's natural-gas ban. While it does not explicitly name lawn equipment, the preemption shadow is real enough that any Arizona charter-city gas-specific GLB ordinance would face a plausible state-law challenge. AG Opinion I18-004 (Brnovich, 2018) further constrains charter-city noise authority against state-recognized equipment specifications. No AZ GLB/SORE bill has been filed in any of the 53rd–57th Legislatures (2017–2026).
