On March 2, 2020, OG&E received approval of the final closure certification for the CCR impoundment located at Muskogee Generating Station from Oklahoma Department of Environmental Quality. As a result, this facility no longer has the reporting requirements of the fugitive dust plan, ground water monitoring and annual reports associated with operating a CCR regulated impoundment.
