Madison, WI (NNCNOW.com) --- The Wisconsin Department of Natural Resources says it needs more data and details from Gogebic Taconite before it can approve bulk sampling activity in the proposed mine area of the Penokee Range. The DNR sent a letter back to Gogebic Taconite after they reviewed the company's Bulk Sample Plan, saying the proposal will require a storm water discharge permit. The DNR went on to say that the company may need further permits, but their submitted plan lacks enough detail to say for sure. In the letter, the DNR says it needs more information from G-tac, including what kind of explosives would be used, air emission estimates, a wetland inventory for the site and anti-erosion and anti-pollution measures. G-tac is currently considering the development of an open pit mine along a four-mile stretch east of the community of Mellen which straddles the boundary between Iron and Ashland counties.
