Solar Tower Project, Halfway Done, Clears Court Hurdle

Just days after marking the halfway point — and peak of employment — in the construction of the 392-megawatt Ivanpah concentrating solar plant, the project’s developers got some good news: work can continue at the desert site near the California/Nevada state line.

Courthouse News Service reported that the 9th U.S. Circuit Court of Appeals upheld a lower court decision denying a preliminary injunction sought by the environmental group Western Watersheds Project. The group claims the Department of the Interior, Bureau of Land Management and Fish and Wildlife Service haven’t complied with federal environmental laws in permitting the project, most notably in failing to protect the threatened desert tortoise.

In its decision [PDF], a three-judge panel of the court said the district court “properly weighed the environmental harm posed by the Ivanpah Solar Electric Generating System project against the possible damage to project funding, jobs, and the state and national renewable energy goals that would result from an injunction halting project construction.”

In January 2011, Western Watersheds sued to stop construction of the plant on “5.4 square miles of high quality habitat” for the desert tortoise. A federal judge denied a temporary restraining order soon after the suit was filed, then later said no to a preliminary injunction.

However, in April 2011, the BLM itself halted construction on two of the three units of the plant after determining that the developers – headed up by BrightSource Energy and NRG Energy, with Google also an investor – “reached, and in some categories, just exceeded the incidental take limit for further construction activities within Ivanpah 2, and Ivanpah 3.” Federal law defines “take” to mean “to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct.”

The problem was that there were a lot more tortoises on the site than had been originally estimated.

So in June 2011, a new Biological Opinion that included “new stipulations for translocating tortoise as well as new requirements for protecting them from predators and increased monitoring and fencing” was issued by the government, allowing work to resume.

The latest ruling doesn’t end the legal battle over Ivanpah; according to Courthouse News, both sides – Western Watersheds and the developers – have filed motions for summary judgment on the case. Then again, with the project motoring along, that might soon be moot.
