Ace Ethanol LLC and John S. Olynick Inc. will pay $61,000 for alleged federal Clean Water Act violations at the company´s Stanley, Wis., plant.

The U.S. Environmental Protection Agency alleges the companies filled in 7,900 square feet of wetlands near the Stanley facility without obtaining a permit. The wetlands are located next to a Wolf River tributary.

The Clean Water Act requires companies to get a permit from the U.S. Army Corps of Engineers to fill in U.S. waters, including wetlands such as marshes, bogs and swamps.
