mining permit modifications

LANSING, MI (AP)--   Mining companies would be able to modify onsite facilities without an environmental permit amendment under legislation that has passed the Michigan House. 

Lawmakers voted 63-45 on Tuesday to advance the bill to grant companies more flexibility in moving and adjusting their mining sites and buildings. The proposed change would allow mining companies to modify the facilities provided they give Michigan's Department of Environmental Quality a 30-day notice and if the changes don't add environmental risk.
