Federal officials will not impose tighter enforcement on the Lucky Friday Mine in Shoshone County after Hecla Mining Co. made safety improvements there.
The Mine Safety and Health Administration warned Hecla last November that the company might receive a notice of a "potential pattern of violations of mandatory health or safety standards" that could lead to more enforcement.
Separate accidents there in 2011 left two miners dead and seven workers briefly trapped 5,900 feet underground. Mining was halted in early 2012, and more than 200 employees and contractors were laid off in response to a federal order to rehabilitate the mine's main shaft. Because of that work and additional safety training for workers, the agency decided the notice is not required, Hecla President and CEO Phillips S. Baker Jr. says. Operations recently resumed.
