Corps takes comment on Duke app for Gibson coal plant

The U.S. Army Corps of Engineers office in Louisville, Ky., will be taking comment until Sept. 2 on a Section 404 Clean Water Act application from Duke Energy for new landfill work for scrubber waste at the coal-fired Gibson power plant in Indiana.

This permitting covers associated wetlands of unnamed tributaries to the Wabash River at the Gibson Station facility, west of Princeton in Gibson County, Ind. A portion of this project includes a request for after the fact permitting for wetland impacts that have been completed without proper Corps authorization. Borrow activities were discovered occurring within jurisdictional wetlands as part of a landfill cover operation. When notified of the violation, Duke Energy ceased the borrow activity within the subject wetlands and prepared an application for Corps authorization.

The project impacts result from a truck/scrapper/shovel  operation to remove borrow material from the wetland and adjacent agricultural areas to provide earthen cover material for both the Gibson Station Flue Gas Desulfurization landfill and the East Ash Pond closure project.

Gibson is a five-unit, 3,145-MW facility that was built between 1976 and 1982. Unit 5 is co-owned by the Wabash Valley Power Association and Indiana Municipal Power Agency. All five units have SO2 scrubbers.
