Site descriptionInterstate Power and Light’s (a subsidiary of Alliant Energy) Lansing Generating Station is in Lansing, Iowa on the Mississippi River in Allamakee County. The facility was originally constructed in 1948, with four coal-fired units and a net capacity of 339-MW at its peak. Three units have since been retired, with Unit 4 the last one remaining. Unit 4 is planned for retirement by the end of 2022. The plant has two unlined ash ponds and an unlined ash landfill. The ash ponds were constructed in the 1970's, and the landfill was constructed in the mid-1980's. Groundwater beneath the site generally flows toward the west-northwest. Lansing’s Upper Ash Pond is scheduled to be closed by October 17, 2023 by a combination of CCR removal, consolidation, and in-place closure with a cap.
