AZ SB1429

Requires the Department of Environmental Quality to adopt a list of burdened communities (census tracts in bottom 33% of state for median household income) within 120 days and update periodically.

Prohibits the department from granting permits for new facilities or expansions in burdened communities unless the applicant prepares an environmental impact report, transmits it 30 days before a public hearing, and conducts a public hearing in a convenient location with notice published in at least two local newspapers 21 days in advance.

Requires the department to wait at least 60 days after the public hearing before issuing a permit decision and allows denial if the cumulative impacts from the new facility combined with existing conditions would pose unreasonable health or environmental risks to residents.

Directs the department to assess community support demonstrated through the public hearing, letters, and any municipal ordinances or resolutions when deciding whether to grant or deny a permit.

Defines "burdened community" by income, "cumulative impacts" as combined past and present emissions affecting a geographic area, and specifies which facilities are covered (electric generators over 10 megawatts, landfills, sewage treatment plants over 50 million gallons per day, waste facilities, and medical waste incinerators).
