A Phoenix-area sand and gravel operation will pay a civil penalty of $150,000 for dust violations, federal environmental regulators said Wednesday.
Fisher Sand and Gravel is also required to take steps to minimize the generation of dust from its south Phoenix plant, according to a consent decree with the Environmental Protection Agency.
The actions stem from inspections by the EPA and Maricopa County Air Quality Department in 2010 that identified 17 violations at Fisher's locations in Buckeye, Sun City and Phoenix.
Those violations included failing to spray water during earthmoving operations and failing to clean up dirt tracked more than 50 feet beyond a site.
Steps the company must take include installing water spray bars to control dust at its Phoenix location and submitting detailed compliance reports.
The EPA says dust is a public health concern because particulate matter affects the respiratory system.
