IVANPAH DRY LAKE, Calif. (AP) — Workers at a state-of-the-art solar plant in the Mojave Desert have a name for birds that fly through the plant's concentrated sun rays — "streamers," for the smoke plume that comes from birds that ignite in midair

Federal wildlife investigators who visited the BrightSource Energy plant last year and watched as birds burned and fell, reporting an average of one "streamer" every two minutes, are urging California officials to halt the operator's application to build a still-bigger version.

The investigators want the halt until the full extent of the deaths can be assessed. Estimates per year now range from a low of about a thousand by BrightSource to 28,000 by an expert for the Center for Biological Diversity environmental group.

The deaths are "alarming. It's hard to say whether that's the location or the technology," said Garry George, renewable-energy director for the California chapter of the Audubon Society. "There needs to be some caution."

The bird kills mark the latest instance in which the quest for clean energy sometimes has inadvertent environmental harm. Solar farms have been criticized for their impacts on desert tortoises, and wind farms have killed birds, including numerous raptors.

"We take this issue very seriously," said Jeff Holland, a spokesman for NRG Solar of Carlsbad, California, the second of the three companies behind the plant. The third, Google, deferred comment to its partners.

The $2.2 billion plant, which launched in February, is at Ivanpah Dry Lake near the California-Nevada border. The operator says it is the world's biggest plant to employ so-called power towers.

More than 300,000 mirrors, each the size of a garage door, reflect solar rays onto three boiler towers each looming up to 40 stories high. The water inside is heated to produce steam, which turns turbines that generate enough electricity for 140,000 homes.

Sun rays sent up by the field of mirrors are bright enough to dazzle pilots flying in and out of Las Vegas and Los Angeles.

Federal wildlife officials said Ivanpah might act as a "mega-trap" for wildlife, with the bright light of the plant attracting insects, which in turn attract insect-eating birds that fly to their death in the intensely focused light rays.

Federal and state biologists call the number of deaths significant, based on sightings of birds getting singed and falling, and on retrieval of carcasses with feathers charred too severely for flight.

Ivanpah officials dispute the source of the so-called streamers, saying at least some of the puffs of smoke mark insects and bits of airborne trash being ignited by the solar rays.

Wildlife officials who witnessed the phenomena say many of the clouds of smoke were too big to come from anything but a bird, and they add that they saw "birds entering the solar flux and igniting, consequently become a streamer."

U.S. Fish and Wildlife officials say they want a death toll for a full year of operation.

Given the apparent scale of bird deaths at Ivanpah, authorities should thoroughly track bird kills there for a year, including during annual migratory seasons, before granting any more permits for that kind of solar technology, said George, of the Audubon Society.

The toll on birds has been surprising, said Robert Weisenmiller, chairman of the California Energy Commission. "We didn't see a lot of impact" on birds at the first, smaller power towers in the U.S. and Europe, Weisenmiller said.

The commission is now considering the application from Oakland-based BrightSource to build a mirror field and a 75-story power tower that would reach above the sand dunes and creek washes between Joshua Tree National Park and the California-Arizona border.

The proposed plant is on a flight path for birds between the Colorado River and California's largest lake, the Salton Sea — an area, experts say, is richer in avian life than the Ivanpah plant, with protected golden eagles and peregrine falcons and more than 100 other species of birds recorded there.

U.S. Fish and Wildlife Service officials warned California this month that the power-tower style of solar technology holds "the highest lethality potential" of the many solar projects burgeoning in the deserts of California.

The commission's staff estimates the proposed new tower would be almost four times as dangerous to birds as the Ivanpah plant. The agency is expected to decide this autumn on the proposal.

While biologists say there is no known feasible way to curb the number of birds killed, the companies behind the projects say they are hoping to find one — studying whether lights, sounds or some other technology would scare them away, said Joseph Desmond, senior vice president at BrightSource Energy.

BrightSource also is offering $1.8 million in compensation for anticipated bird deaths at Palen, Desmond said.

The company is proposing the money for programs such as those to spay and neuter domestic cats, which a government study found kill over 1.4 billion birds a year. Opponents say that would do nothing to help the desert birds at the proposed site.

Power-tower proponents are fighting to keep the deaths from forcing a pause in the building of new plants when they see the technology on the verge of becoming more affordable and accessible, said Thomas Conroy, a renewable-energy expert.

When it comes to powering the country's grids, "diversity of technology ... is critical," Conroy said. "Nobody should be arguing let's be all coal, all solar," all wind, or all nuclear. "And every one of those technologies has a long list of pros and cons."

Finding a fix for dying Salton Sea

After years of inaction by state, lawmaker wants to put regional group at helm

NORTH SHORE — As state lawmakers held their first summit in more than four years on the looming death of the Salton Sea, Sonia Herbert gazed out the window at the North Shore Beach & Yacht Club marina, where squawking seabirds swooped across the glassy sea surface, fishing for tilapia.

Like most of the 60 people who attended Monday's hearing, Herbert, who has lived in Bombay Beach since the 1970s, fears the worst: that time is running out on efforts to repair the sea and sustain its wildlife, and that overwhelming public health and economic crises will follow.

“All we've seen is studies, studies, studies and nothing has been done,” a visibly frustrated Herbert told Assemblyman V. Manuel Pérez and two Assembly budget committee members. “What's going to happen if we don't do something?”

The state remains broke, and its preferred $9 billion sea restoration plan has languished since 2007.

Sticker shock over the restoration cost has led to political paralysis, but Pérez, a Coachella Democrat whose district includes the sea, has called its restoration his top priority for the rest of his legislative tenure.

At the hearing, which Pérez's office organized, he listened to county supervisors, residents and environmental advocates call for the state to relinquish control and to let locals settle on the best plan to restore the sea and the best way to pay for it.

“The sea needs help and it needs it now. The answer isn't big brother riding to the rescue, because he's not coming. There is no rescue,” Imperial County Supervisor Gary Wyatt told Pérez and two other Assembly members, Republican Brian Jones of Santee and Democrat Richard Gordon of Menlo Park.

“We need to drive this train,” said Wyatt, quoting longtime Riverside County Supervisor Roy Wilson, who died in 2009.

Wyatt and others pushed public-private partnerships on new geothermal and solar energy projects at the sea as a realistic way to tap dollars for Salton Sea restoration.

Wyatt proposed taking a 7,000-acre former military test site at the sea's south shore, now controlled by the federal Bureau of Land Management, and converting it into a renewable energy depot that he said could provide 700 megawatts of power and produce at least $40 million a year in restoration funds.

Unlike redevelopment funds, that money would be exempt from state seizure, Wyatt said after the meeting.

“The interest is here, not there,” Riverside County Supervisor John Benoit said, referring to Sacramento. “What we need is the authority. If we fix this sea… the economic advantages to this area (are) nearly unlimited.”

Pérez said he hoped the hearing would help drum up support in the Legislature for his AB 939 bill, a proposal to switch the authority from the state's Salton Sea Restoration Council — a body that has never met — and place it in the hands of the local Salton Sea Authority, a joint-powers authority of the local counties and local water districts, along with some state presence.

“I'm optimistic that we can find a way if we work together and there's a political will from all levels of government including grassroots,” Pérez said. “Part of the reason why we have not been able to move forward is we're all moving in so many different directions. We need to find consensus to what the issues of the Salton Sea are.”

As runoff from irrigation and other water transfers evaporate, the Salton Sea's salinity has risen while its mass has shrunk. By the end of this decade, its retreat will be even more dramatic.

Created by flooding in 1905 and without a new source of water to replenish it, California's largest lake will grow uninhabitable to fish and the thousands of migratory birds that feed on them.

The exposed lakebed and the dust it generates could be disastrous in an area that already has one of the nation's highest rates for youth asthma, officials say. It also would damage agriculture and tourism.

State budget analysts at the hearing Monday reported that tens of millions of dollars in state bond funds from Propositions 50 and 84 have been spent on proposals for the sea's multi-billion-dollar fix, though exactly where the money went wasn't made clear.

“We've spent more than half our bond money … We don't have much to show for it, frankly,” said Kimberley Delfino, California program director of the national nonprofit Defenders of Wildlife.

“This is shameful and frightening,” Delfino said. “When you've lost 95 to 98 percent of the wetlands in California, the birds don't have any other place to go. The situation at the Salton Sea is grim and the stakes are high. We need a new governance structure, now. There isn't a lot of time left.”

As for the immediate next step, Pérez said he hopes for a meeting between Defenders of Wildlife, the Salton Sea Authority, the state's Legislative Analyst's Office, and other stakeholders.

“The sea still has its strong supporters, fighters and believers,” Wyatt said. “There are ways to make the revenues happen.”

Don’t Mince Birds

Wind power for Los Angeles faces down a new foe

It began with a fanfare that fast became a public-relations nightmare; it has been stalled for nearly a year awaiting impact reports. And just when it seemed poised to go forward in advance of a mayoral election that could be decided by a handful of environmentalist votes, the Pine Tree Wind Farm has hit yet another obstacle: the defenders of the hundreds of songbirds that some ornithologists believe fly through the proposed 22,000-acre site in the Mojave Desert every year.

“It’s a prime location on the north-south migration pattern every fall and spring,” says Garry George, first vice president and conservation chair of the Los Angeles Chapter of the Audubon Society. “Flycatchers, warblers, vireos, those kinds of birds.” An environmental impact report (EIR) published in July 2004 acknowledged potential harm to red-tailed hawks, but estimated that Pine Tree’s 80 turbines would kill only four raptors per year (the average among all North American wind farms is 2.19 deaths per year) — not much impact to a healthy population. But there’s no evidence in the EIR that anyone even observed a single songbird. “They visited only one time and only for an hour during the birds’ peak migration period, which is April 15th to May 30th,” George says. “How could they conclude it wasn’t harmful to songbirds if they weren’t there when most birds come through?”

A proposed $162 million project that would supply clean energy to 120,000 Los Angeles homes, the Pine Tree Wind Farm could help the DWP meet a goal of 20 percent renewable energy by 2017, as set by the Los Angeles City Council last year. The DWP’s own Web site boasts that the project will reduce the utility’s carbon-dioxide emissions “by more than 210,000 tons each year.”

That obviously thrills clean-energy advocates, who say the DWP has been notoriously sluggish on clean power. “The DWP’s mantra is to build dirty coal plants out of state,” says Rhonda Mills, director of special projects for the Center for Energy Efficiency and Renewable Technologies (CEERT). “They prefer to diminish visibility in national parks in Utah than put any effort into wind or solar. For us this wind farm is a very promising project compared to what we’ve built in the last 30 years.

“But that doesn’t mean you do it at the expense of everything,” Mills cautions. “It means that you do it right, with all the reports in place.”

George agrees. “We don’t object to wind power in general; we just want them to do all the studies.”

Bird enthusiasts have found little comfort in the histories of other California wind farms, such as the Altamont Pass Wind Resource Area in eastern Alameda and Contra Costa Counties. In addition to killing anywhere from 800 to 1,200 birds of prey a year, including the protected golden eagle, Altamont’s mills also chew up some 3,000 meadowlarks and nearly 400 burrowing owls. The Center for Biological Diversity has filed suit against several companies managing the wind farm alleging unfair business practices (Wind Turbine Prometheus, which will develop Pine Tree with General Electric turbines, is not among them). Even the California Energy Company has recommended retiring the facility’s most lethal turbines.

“Wind turbine owners are not doing enough to mitigate bird and bat mortality,” says K. Shawn Smallwood, an independent ecologist specializing in minimizing bird kills on wind farms who worked on the Pine Tree draft EIR. “What the wind industry is doing right now is denying there’s a problem,” he says. “That’s too bad, because there’s a way to make wind power truly green. They just won’t do it.”
