The company proposing to build the Rosemont Mine is raising the possibility of challenging the U.S. Army Corps of Engineers’ authority to regulate washes on the site if the Corps denies a permit to build the project.
Federal jurisdiction over those washes hasn’t been questioned since Rosemont Copper first announced its plans to build the $1.5 billion project a decade ago. The company, now owned by Toronto-based Hudbay Minerals Inc., applied for a Clean Water Act permit for the project back in 2011 and announced its intention to apply in 2008.
