A company that's installed an experimental power plant in the Mississippi River near Hastings says it will conduct new studies on the potential impacts of the project.
The plant creates power from a turbine that's suspended underwater.
The Mississippi National River and Recreation Area, part of the National Park Service, asked the federal government to reconsider the permit for the project.
The Park Service says there hasn't been enough study to find out how fish and eagles and other wildlife might be affected.
Mark Stover is Vice President of Hydro Green Energy, the company that installed the turbine. He says it's committed to doing the studies.
"We want to perform these studies, and more important, we want to get this information out to the public, no other developer has committed to doing that, and our studies as of today are costing us over $500,000, and that's not an easy for an innovative start-up company to do," Strover said.
The Federal Energy Regulatory Commission is giving itself more time to decide whether to respond to the Park Service concerns.
