Mingo Logan Coal Co. v. EPA

Mingo Logan applied to the Corps for a permit under section 404 of the Clean Water Act (CWA), 33 U.S.C. 1344, to discharge dredged or fill material from a mountain-top coal mine in West Virginia into three streams and their tributaries. The Corps issued the permit to Mingo Logan, approving the requested disposal sites for the discharged materials. Four years later, the EPA invoked its subsection 404(c) authority to “withdraw” the specifications of two of the streams as disposal sites, thereby prohibiting Mingo Logan from discharging them. Mingo Logan then filed this action challenging the EPA’s withdrawal of the specified sites. The court reversed the district court’s grant of summary judgment to Mingo Logan and concluded that the EPA had post-permit withdrawal authority. Accordingly, the court remanded for further proceedings.
