Revises provisions relating to air quality. (BDR 53-961)

The bill now specifically targets 'wildfire smoke' and applies only to employees who 'occasionally, frequently or constantly perform critical tasks outdoors,' replacing the broader language regarding general poor air quality and all employees.

The threshold for requiring employer action was changed from a single limit of 150 to a tiered system covering an Air Quality Index of 150 or more but less than 200, and 200 or more.

Air quality monitoring requirements were updated to prioritize AirNow as the primary source, with specific fallback options for other agencies, and monitoring must occur as conditions change during each shift.

The list of exempt employers was expanded to include operators of mines and commercial truck drivers, in addition to emergency service providers and small businesses.

Changed from requiring employers to directly establish safety programs to requiring the Administrator to adopt regulations first, then requiring employers to comply with those regulations.

Added requirement for employers to establish a communications system that informs employees about air quality exposure and allows them to report symptoms.

Added specific air quality index thresholds (150-200 and 200 or more) that the Administrator must regulate for exposure reduction measures.

Maintained existing exemptions for mine operators, commercial truck drivers, emergency service providers, and employers with 10 or fewer employees.

Added provision prohibiting regulations from imposing additional liability on employers for insurance purposes.
