MidAmerican Energy’s Walter Scott Jr Energy Station is in Bluffs, Iowa on the banks of the Missouri River in Pottawattamie County. Opened in 1954, at its peak this plant could produce a combined 1,779-MW of electricity. In 2015, MidAmerican Energy retired Units 1 and 2 in the wake of a 2013 lawsuit settlement between MidAmerican Energy and the Sierra Club. Closure and post-closure plans have been put in place for Plant Walter Scott Jr’s CCR surface impoundment. Plant Walter Scott Jr’s South Surface Impoundment and Monofill are regulated under the CCR rule.
