Arizona dry cleaners can now use more petroleum solvents without violating air quality rules

US environmental regulators are proposing to approve new definitions for petroleum solvents used in dry cleaning in Maricopa County, Arizona. This change means dry cleaners can use a wider range of these solvents without violating local air quality limits on volatile organic compounds.

Local air quality rules often rely on specific definitions for chemicals. When those definitions are too narrow, businesses might struggle to comply, or they might be forced to use more expensive alternatives. This update gives dry cleaners more flexibility in the types of solvents they can use, potentially lowering their operating costs.
