Site description

Otter Tail Power Company’s Plant Hoot Lake is located in Otter Tail County, MN, along the banks of an unnamed creek. Plant Hoot Lake began operations in 1959 and operated two coal-fired units with a combined generating capacity of 129 MW. Plant Hoot Lake is scheduled to be converted to run completely on natural gas by 2020. This plant currently operates a singular CCR Landfill that is regulated under the CCR rule.
