CINCINNATI - A federal judge in Kentucky did not err in dismissing claims brought by two environmental groups challenging the U.S. Army Corps of Engineers' decision to provide a mining company with a permit under the Clean Water Act (CWA), a Sixth Circuit U.S. Court of Appeals panel ruled March 7, finding that the Corps properly considered the environmental impact of the company's operations (Kentuckians for the Commonwealth, et al. v. U.S. Army Corps of Engineers, et al., No. 13-6153, 6th Cir.; 2014 U.S. App. LEXIS 4267).
