HB 2013: exceptional events; air quality; wildfires

Sponsor: Representative Fink, LD 27

Vetoed by the Governor

Overview

Directs the Arizona Department of Environmental Quality (ADEQ), if a wildfire occurs on federally managed land, to file an exceptional event demonstration to the Environmental Protection Agency (EPA).

History

Exceptional events are unusual or naturally occurring events that can affect air quality but are not reasonably controllable using techniques that tribal, state or local air agencies may implement in order to attain and maintain the National Ambient Air Quality Standards (NAAQS). Exceptional events may include wildfires, high wind dust events, prescribed fires, stratospheric ozone intrusions and volcanic and seismic activities.

The Clean Air Act authorizes events that are designated as exceptional events to be excluded from air quality monitoring data for the purposes of determining attainment of the NAAQS. For an event to be designated as an exceptional events, tribal, state or local air agencies may prepare and submit an exceptional event demonstration and submit it to the EPA for consideration (EPA).

Provisions

1.   Requires the ADEQ, if a wildfire occurs on federally managed land that affects the state, to submit an exceptional event demonstration to the EPA. (Sec. 1)

2.   Specifies that a wildfire, for the requirement for the ADEQ to submit an exceptional event demonstration, must be larger than 25,000 acres and be attributable to smoke or land damage.
