In 2019, City Council passed the Baltimore Clean Air Act, which forced private waste incinerators to cut down on pollutants. But the incinerator operators sued, and a federal judge in March ruled in their favor. The city filed a request for the 4th U.S. Circuit Court of Appeals to reconsider that decision. Since then, the city has been in settlement negotiations with incinerator operators, a fact that alarms environmentalists, said Mike Ewall of Energy Justice Network, which advocates for shutting down incinerators.
