Environment (Air Quality)

LD 1407 directs Maine's Board of Occupational Safety and Health to develop indoor air quality standards for buildings where public sector workers (such as teachers, government employees, and healthcare staff in public facilities) work. The bill requires the board to establish standards covering specific pollutants including carbon monoxide, mold, volatile organic compounds, and aerosols, with aerosol rules meeting or exceeding ASHRAE Standard 241 (2023). The board must publish proposed rules by February 15, 2026, under routine technical rule procedures. These standards will apply exclusively to public-sector workplaces, not private buildings.

LD 1887 requires Maine's Department of Education to amend school construction rules to set air quality and ventilation standards specifically for newly built public schools. This replaces a prior requirement that applied to all public schools, focusing the new standards solely on new construction (not existing schools). The updated rules must be adopted by January 4, 2026, and will apply to all new public school buildings completed between July 1, 2022, and July 1, 2026.
