MN SF4520

Requires the Pollution Control Agency commissioner to analyze cumulative environmental pollution effects before issuing air emissions permits for facilities in designated "highly impacted areas" in first-class cities in Hennepin County.

Requires cumulative impact analysis when air permits are not required if a petition signed by residents is submitted before a project receives final approval, with the commissioner responding within a specified timeframe.

Prohibits demolition of buildings containing 200,000 or more square feet in highly impacted areas until the commissioner analyzes cumulative pollution effects from demolition and any planned redevelopment.

Defines "highly impacted area" as a location within a first-class city in Hennepin County meeting six criteria: proximity to EPA superfund site with arsenic contamination, majority low-income persons of color and American Indians, disproportionate childhood health problems, history of air quality alerts (February 2007-2008), proximity to heavy traffic corridors, and increased COVID-19 vulnerabilities based on documented racial health disparities.

Allows the commissioner to require mitigation provisions in permits and prohibits political subdivisions from issuing final project approval when a cumulative impact petition has been submitted until the commissioner completes analysis or determines significant emissions are unlikely.
