The Geysers getting credit for a cleaner Russian River

Valuable scrap that contains iron is separated so it can be turned back into steel. Hunks of aluminum, copper and other alloys are pulled out for reprocessing.
But the leftovers -- bits of glass, fiber, rubber, engine fluids, dirt and plastics -- are getting new attention from state toxic substance regulators, and the $500-million-a-year shredding industry is fighting back.
For years, auto-shredding companies have been hauling tons of these treated leftovers, known in the industry as fluff, to municipal landfills under a state variance granted more than 20 years ago.
State officials now say they are concerned that residue from heavy metals in the fluff could seep from landfills into groundwater, while airborne metal-laden particles could endanger workers at recycling plants and dumps and people living in neighborhoods near such facilities.
The industry maintains that the 700,000 tons of material it delivers to landfills each year pose no threat to health or safety.
A change in state policy, if finalized, could mean that fluff may need to be transported under more strict conditions to special hazardous waste disposal sites, according to the state Department of Toxic Substances Control.
"We are of the opinion that the way cars are made is quite a bit different than 20 years ago," said Colleen Heck, a department senior staff counsel. "We're seeing increased amounts of lead, zinc and cadmium in the waste stream, so we think it's no longer appropriate to allow them to operate" the same way they have in the past.
The department, which originally put the shredding industry on notice of a likely change in September, has twice granted extensions. The current deadline for making a final decision is June 30.
Recyclers dismiss the health concerns as baseless. They fear that being subjected to more stringent regulation could double or triple disposal costs, according to an industry-sponsored economic analysis. The proposed rules unintentionally could create more pollution by spurring recyclers to truck their fluff to distant, out-of-state dumps that have no restrictions on what they take.
"Given the ranges of exposure we are seeing, it doesn't cause any threats to human health or the environment," said Margaret Rosegay, an attorney for the
Current fluff disposal standards already are the toughest in the nation, Rosegay said.
Recyclers say they treat the fluff by coating it with cement during a chemical reaction that "fixes" the heavy metals and prevents seeping or leaching.
After treatment, the fluff is hauled to landfills, where it is spread 6 inches deep over each day's dumpings to tamp down odors and keep birds, rats and other animals from getting at the garbage.
Treated fluff is an economical alternative to using sometimes scarce dirt to cover landfills, recyclers argue.
Environmental groups, which applaud the department's push for more stringent shredding standards, question the safety of using treated fluff as landfill daily cover.
"If you put hazardous waste on a landfill, it will ultimately make its way into our water supply," said Bill Magavern,
To underscore his concern, Magavern noted that the San Pedro auto shredding plant and another facility in
The search warrant signed by a Los Angeles County Superior Court judge asked for information about a reported explosion that damaged an air pollution control system and allowed the discharge of allegedly hazardous particles. The warrant also looked for evidence of the illegal transportation of hazardous waste to an unpermitted facility.
The district attorney's office confirmed that the search warrant was served but declined to comment on its continuing investigation.
The investigation is based on the testimony of "disgruntled former employees" of a predecessor of SA Recycling, said Robert Hoffman, an attorney for the company. The probe has nothing to do with the state's proposal to increase regulation of auto shredder fluff, he said.
Hoffman, who was a top lawyer at the Department of Toxic Substances Control in the 1990s, is part of a team of attorneys, lobbyists and political strategists mounting a campaign in both the regulatory arena and the Legislature to forestall the proposed change in disposal regulations.
The industry is backing a bill by Sen. Lou Correa (D-Santa Ana), whose district is home to SA Recycling, that would prohibit the toxics department from tightening controls on fluff until after the California Environmental Protection Agency delivers a report on the issue to lawmakers in December 2010.
Correa, who received $3,600 in campaign contributions from SA Recycling in 2007 and 2008, said his bill would ensure that any proposed rule changes would be studied jointly by all
That coordination already is taking place, said BreAnda Northcutt, a spokeswoman for Cal/EPA, which oversees Toxic Substances Control as well as the boards that deal with air and water quality.
Toxic Substances Control "has been collaborating with Cal/EPA departments," Northcutt said. "They've also worked with local agencies and landfills to help them better understand the changes."#

The Geysers getting credit for a cleaner Russian River

The biggest reason the
The steam fields, which convert wastewater into steam to generate electricity, consumed 65 percent of the highly treated effluent generated by
Before The Geysers' wastewater-to-electricity project was completed in late 2003, most of that effluent would have gone down the river during winter months.
"I had a gut feeling when the city picked The Geysers project it would be a really good thing," said Brenda Adelman of Guerneville, a river activist. She has been at the forefront of demands by river residents that the city dramatically reduce its river discharges.
"It's turned out better than I anticipated. It's so much better putting it there than in the river," she said.
Since the $300 million project, a partnership between the city and Calpine Corp., became operational, the city has pumped 21 billion gallons of effluent from its
Dennis Gilles, Calpine's senior vice president, said the effluent now generates 96 megawatts of steam-generated electricity, or about 10 percent of the 1,000 megawatts the geothermal area generates.
That's enough to power 96,000 homes or the combined daily residential needs of
Gilles said the wastewater has done one more important thing: It has re-energized the steam fields, which literally had been losing steam because of the lack of sufficient rainwater to replenish underground aquifers.
"It's been a win-win," said Gilles, whose company spent more than $100 million to develop a series of injection wells, distribution pipelines, storage and generating facilities to handle the flows within the 30-square-mile steam field area, the largest concentration of steam fields on Earth.
The city originally signed a contract to provide Calpine with 11 million gallons of wastewater a day, or 4 billion gallons a year, but upped that amount two years ago when it reached a new agreement.
That contracts require the city to provide Calpine with 12.6 million gallons of effluent on average per day but calls for a gradual increase up to 16 million gallons, or 6 billion gallons a year, over the next two to three decades.
By then, Gilles expects the increased flows will produce up to 150 megawatts of electricity, roughly enough to power the residential needs of all of
