Maricopa County can now enforce tighter air pollution rules for solvent cleaning and crematories

The US environmental regulators have approved new air quality rules for Maricopa County, Arizona. This means the county can now enforce stricter limits on pollution from solvent cleaning, architectural coatings, incinerators, burn-off ovens, and crematories.

Local governments often struggle to enforce environmental rules without federal backing. This approval means Maricopa County's air quality department has the legal authority to fine businesses that exceed these new pollution limits. It shifts the burden of compliance directly onto specific local businesses, rather than leaving it to broader state or federal oversight.
