This bill establishes a task force aimed at improving indoor air quality in highly-impacted communities, including schools, long-term care facilities, correctional facilities, early childhood education facilities, public housing, and privately-owned residential buildings. The task force will be chaired by the commissioner of public health and will include representatives from various sectors, such as environmental justice organizations, health boards, labor unions, and experts in environmental health and indoor air pollution. The task force is required to convene within 30 days of the bill's passage and must submit a final report with recommendations within one year, including draft recommendations for public review at least 30 days prior to the final report's release.

Additionally, the bill mandates the Department of Public Health, in consultation with the Department of Environmental Protection, to create regulations for indoor air quality assessments that monitor exposure to ultrafine particulate matter and black carbon in existing and proposed buildings. These regulations will be based on the best available science regarding health risks and will include standard procedures for air dispersion modeling and public reporting mechanisms. The Department of Public Health is required to finalize these regulations by July 31, 2027.
