The U.S. Environmental Protection Agency says Navajo Mesa Farms agreed to pay about $6,000 to settle four violations from 2013 and 2016.

The company has an office in Farmington and grows potatoes on tribal land.

The EPA says the company didn’t post pesticide safety information for workers or indicate a buffer zone for fumigants that would keep bystanders from the area.

The agency says the company also didn’t check that workers’ respirators fit properly.

The settlement agreement was finalized late last month.
