Anheuser-Busch has agreed to pay $537,000 in penalties and conduct a safety review of all 11 of its breweries that use anhydrous ammonia, the U.S. Environmental Protection Agency said.

The settlement, which includes the company’s brewery in Merrimack, resolves violations of the Clean Air Act’s chemical accident prevention requirements and the Emergency Planning and Community Rightto-Know Act, the agency said in a news release.

The safety review also will occur at facilities located in California, Colorado, Texas, Ohio, Florida, New York, Virginia, Georgia and Missouri.

“Accidental releases of anhydrous ammonia are dangerous and can be deadly,” said Acting Assistant Administrator Larry Starfield for EPA’s Office of Enforcement and Compliance Assurance, in a statement.

Between 2016 and 2019, the EPA said it conducted inspections at Anheuser-Busch’s facilities in Merrimack, Fort Collins, Colorado, and Fairfield, California.

The EPA also investigated an ammonia release that occurred in 2018 at Anheuser-Busch’s Fort Collins facility and injured two employees, the agency said.
