Air Sensor Grant Clarification and Efficiency Act of 2025

Generated by VFA SI Solutions

Improve air quality monitoring by allowing existing Clean Air Act grants to be used for purchasing air sensors, without creating new programs or authorizations.

Bipartisan rationale: Honors Democratic priorities by expanding tools for air quality monitoring, particularly in underserved communities, and by requiring public data access. Honors Republican priorities by avoiding new spending, limiting federal expansion to a narrow clarification, and including a sunset provision to ensure accountability and review.

Funding: Existing appropriations for Clean Air Act Not specified; cap is the exis Sunset 5y Oversight: Environmental Protection Agenc Enforcement: Standard grant compliance procedures
