From Reuters:

A U.S. conservation group has sued the federal government over its approval of a major solar power plant in the California desert, the latest in a string of challenges to the nation's renewable energy goals from the environmental community.

According to court papers, the non-profit Western Watersheds Project alleged U.S. regulators approved Brightsource Energy's 370-megawatt Ivanpah solar energy plant without conducting adequate environmental reviews, and asked the court to order the defendants to withdraw their approvals.

The complaint names the U.S. Department of the Interior, the Bureau of Land Management and the Fish and Wildlife Service, as well as the agencies' heads and other staffers, as defendants. None was immediately available for comment.
