Designation of Critical Habitat for the Vermilion Darter: Proposed rule.

We, the U.S. Fish and Wildlife Service, propose to designate critical habitat for the vermilion darter (Etheostoma chermocki) under the Endangered Species Act of 1973, as amended. We propose to designate as critical habitat approximately 21.0 kilometers (13.0 stream miles) in 5 units. The proposed critical habitat is located within the Turkey Creek watershed in Jefferson County, Alabama.
