SEATTLE (AP) — A century-old Seattle barrel company has been indicted in what prosecutors are calling a long-running pollution conspiracy. The U.S. indictment made public Wednesday says Seattle Barrel and Cooperage used a hidden drain to pump caustic wastewater directly into the King County sewer system. Prosecutors say the waste can wind up in waters that are home to protected salmon, orcas and other species. Seattle Barrel is blaming a former employee who was fired nine months ago. The company says it didn’t encourage or permit that worker’s actions. The former employee hasn’t been charged. The indictment names Seattle Barrel’s owner, whose grandfather founded the company in 1916.
