MARQUETTE, Mich. (AP) - State regulators say they’ve approved revisions to a surface water discharge permit for the Eagle Mine’s Humboldt Mill in the Upper Peninsula.

The Michigan Department of Environmental Quality says Wednesday that the permit safeguards wetlands and the middle branch of the Escanaba River.

The DEQ placed a draft permit on public notice in December and held a public hearing in January. The agency says revisions made in response to public comment include cutting the total authorized flow in half, from 2.8 million gallons per day to 1.4 million gallons per day.

The Mining Journal of Marquette reports the authorized flow is double the previous limit of 720,000 gallons per day.

Production of nickel and copper began last fall at the mine in northwestern Marquette County.
