Arizona farmers must now control dust from their fields and feedlots

US environmental regulators are approving new rules for Arizona to control dust pollution. This means farms in Pinal County will have to change how they manage crops and animal operations to reduce airborne dust.

For years, agricultural operations have often been exempt from air quality rules that apply to other industries. This approval means that specific farming practices in Arizona will now be regulated like other sources of pollution. It sets a precedent for how states can address agricultural emissions under federal clean air laws.
