Requires the Pollution Control Agency commissioner to prepare cumulative impact analysis for air emissions permits in "highly impacted areas" and consider past and current pollution from all sources on the environment and residents.

Allows residents (200+ individuals) to petition for cumulative impact analysis of projects without air permits; commissioner must respond within 30 days with timeline and political subdivisions cannot issue final approval until analysis is completed.

Requires demolition permits from the commissioner for structures of a certain size (amount unspecified in bill) in highly impacted areas, with analysis of cumulative pollution from demolition and planned redevelopment.

Defines "highly impacted area" as a first-class city in Hennepin County meeting five criteria: within half mile of EPA superfund site for arsenic contamination; majority low-income persons of color and American Indians; disproportionate childhood lead poisoning/asthma rates; experienced air quality alert days in 2007-2008; located near heavily trafficked highways and one-way streets; and COVID-19 pandemic vulnerabilities related to health disparities.

Becomes effective the day following final enactment.
