Two environmental groups and a tribe said Oct. 1 they plan to sue the federal government for not responding fast enough to a petition to protect a minnow in western Utah.

The notice to sue focuses on the least chub, a minnow native to the Bonneville Basin.

Environmental groups asked the U.S. Fish and Wildlife Service in June 2007 to protect the fish under the Endangered Species Act. The agency did not respond within the required 12 months, the groups said.
