New Study: Fracking Pollution Poses Major Threat to California’s Air, Water

Scientists’ Warnings Come Too Late to Shape State’s Weak Fracking Regulations

July 15, 2015

SACRAMENTO, Calif.— A study released today by the California Council on Science and Technology warns that fracking and other oil extraction techniques emit dangerous air pollution and threaten to contaminate California’s drinking water supplies. Millions of Californians live near active oil and gas wells, which exposes them to the air pollutants indentified in the report.

The troubling findings come a week after Gov. Jerry Brown’s oil officials finalized new fracking regulations that do little to address such public health and water pollution risks.

“This disturbing study exposes fatal flaws in Gov. Brown’s weak fracking rules,” said Hollin Kretzmann of the Center for Biological Diversity. “Oil companies are fouling the air we breathe and using toxic chemicals that endanger our dwindling drinking water. The millions of people near these polluting wells need an immediate halt to fracking and other dangerous oil company practices.”

Last week the state’s Department of Conservation began implementing new fracking regulations and finalized an assessment of fracking’s health and environmental risks, even though the science council had not finished evaluating fracking’s dangers. The science council is an independent, nonprofit organization that advises California officials on policy issues.

Today’s report concludes that fracking in California happens at unusually shallow depths, dangerously close to underground drinking water supplies, with unusually high chemical concentrations. That poses a serious threat to aquifers during the worst drought in California history.

Air pollution is also a major concern. In the Los Angeles area, the report identifies 1.7 million people — and hundreds of daycare facilities, schools and retirement homes — within one mile of an active oil or gas well. Atmospheric concentrations of pollutants near these oil production sites “can present risks to human health,” the study says.

But Gov. Brown’s new fracking regulations do not address deadly air pollutants like particulate matter and air toxic chemicals. A recent Center analysis found that oil companies engaged in extreme oil production methods have used millions of pounds of air toxics in the Los Angeles Basin.

Among the science council’s other disturbing findings:

  • California places no limits on how close oil and gas wells can be to homes, schools or daycare facilities, which can expose people to dangerous air pollution from fracking and other oil extraction procedures.
  • Serious concerns are raised over the oil industry’s disposal of fracking waste fluid and produced water into open pits and the use of oil waste fluid to irrigate crops.
  • The health and water pollution impacts of fracking chemicals that could be present in oil waste that’s dumped into open pits “would be extremely difficult to predict, because there are so many possible chemicals, and the environmental profiles of many of them are unmeasured.”
  • Wildlife habitat can be fragmented or lost because of fracking and other oil development – and fracking-related oil development in California “coincides with ecologically sensitive areas” in Kern and Ventura Counties.
  • Confirmation that many oil industry wastewater injection wells are close to active faults — a practice has triggered earthquakes in other states. The science council identified more than 1,000 active injection wells within 1.5 miles of a mapped active fault — and more than 150 are within 656 feet.

“These troubling findings send a clear message to Gov. Brown that it’s time to ban fracking and rein in our state’s out-of-control oil industry,” Kretzmann said. “California should follow the example set by New York, which wisely banned fracking after health experts there concluded this toxic technique was just too dangerous.”

SACRAMENTO, Calif – A new report says hydraulic fracturing can contaminate groundwater when the excess water is not properly disposed of, but is not linked to earthquakes in California.

In January, a study by the Seismological Society of America linked a series of earthquakes in Ohio to fracking, and there have been similar claims in other states as well.

The new study released Thursday comes from the California Council on Science and Technology and the Lawrence Berkeley National Laboratory. Jane Long, the lead scientific researcher, says hydraulic fracturing poses some safety concerns but they’re manageable.

“A lot of things people were concerned about are things that are not as big a problem as they think they are,” says Long. “And some of the practices are things that need to change and need more attention.”

The report says the oil companies should phase out percolation ponds used to dispose of excess water because toxic fracking chemicals can get into the aquifer. And it recommends companies put aside about a third of the chemicals currently in use because there’s not enough data about them.

The Center for Biological Diversity points to the finding that oil operations can pollute the air in their immediate vicinity. Long is optimistic that the report will spur further reforms.

“Some of them are going to be recommendations that will be very easy to act on right away and I think they will be acted on and some of them are going to require some process,” she says.

The report was required by the 2013 passage of State Senate Bill 4, which established new safety measures for fracking, rules that went into effect on July 1.

The head of the California Department of Conservation, Mark Nechodom, abruptly resigned Thursday following an outcry over oil companies injecting their wastewater into Central Valley aquifers that were supposed to be protected by law.

Nechodom, who had led the department for three years, announced his resignation in a brief letter to John Laird, secretary of the California Natural Resources Agency. The Conservation Department is part of the resources agency.

“I have appreciated being part of this team and helping to guide it through a difficult time,” Nechodom wrote.

Nechodom did not give a reason for his departure. But a division of the Conservation Department that regulates oil-field operations has come under intense criticism for letting oil companies inject wastewater into aquifers that could have been used for drinking or irrigation.

A spokeswoman for the Natural Resources Agency said she could not comment on Nechodom’s reasons for leaving, calling it a personnel issue. Jason Marshall, the Conservation Department’s chief deputy director, will lead the department while a permanent replacement is sought.

The department’s Division of Oil, Gas and Geothermal Resources for years improperly issued hundreds of wastewater injection permits into aquifers that should have been protected by the federal Safe Drinking Water Act, a problem detailed in a Chronicle investigation in February.

By the division’s most recent count, 452 disposal wells went into aquifers whose water, if treated, could have been used for drinking or irrigation. Another 2,021 wells pumped wastewater or steam into aquifers that also contain oil, with the injections helping to squeeze more petroleum from the ground.

California oil fields typically contain large amounts of water that must be separated from the petroleum and disposed of, usually by pumping it back underground. But oil companies can inject their “produced water” only into aquifers that have been specifically approved for wastewater storage by the federal Environmental Protection Agency.

The division has shut down 23 injection wells deemed to pose the greatest threat and has committed to closing the rest in stages over the next two years. So far, the injections have not been found to have contaminated any wells used for drinking water.

The injections, and the division’s schedule for closing them, have prompted lawsuits, including one filed this week that named Nechodom as a defendant. That suit, filed on behalf of Central Valley farmers, alleges Nechodom, Gov. Jerry Brown and oil companies engaged in a conspiracy to circumvent the law.

Before Brown picked him to lead the Conservation Department, Nechodom had been a senior policy adviser for the U.S. Department of Agriculture. He had also served as a senior climate science policy adviser to the chief of the U.S. Forest Service.

Until this year, however, he might have been best known as the husband of former California Secretary of State Debra Bowen, who completed her term in 2014 after revealing that she was battling severe depression that left her unable to work on many days.

Exxon seeks to use trucks to haul oil after pipeline break

SANTA BARBARA, Calif. —An oil company wants to use tanker trucks to haul oil through Santa Barbara County while a pipeline that spilled crude into the Pacific Ocean last month is out of commission.

Exxon Mobil officials have told county officials they want to use a fleet of 5,000-gallon tankers for the job, the Los Angeles Times reported Friday.

Kevin Drude, head of the county’s energy division, said the company proposes to have trucks use Highway 101 daily, around the clock at a rate of eight trucks an hour to get the oil moving to refineries.

Exxon Mobil normally moves crude from three offshore platforms through more than 10 miles of pipeline owned by Plains All American Pipeline.

The movement has been stopped since the pipe ruptured on May 19 and released up to 101,000 gallons west of Santa Barbara. Thousands of gallons flowed down a culvert under Highway 101 and into the ocean at Refugio State Beach.

The trucking proposal is seen as risky by environmentalists.

“We don’t want another disaster,” said Linda Krop, chief counsel for the Santa Barbara-based Environmental Defense Center.

Glenn Russell, county planning and development director, said his staff will review the proposal and make a decision by Monday. He said he expects a similar request from another oil company, Freeport-McMoRan, which has also been affected by the pipeline shutdown.

Cleanup and investigations into corrosion that resulted in the failure of the pipe have been underway since the spill and there’s no timetable for putting the pipeline back in service.

Exxon Mobil would use the trucks until the pipeline is operational again, said company spokesman Richard Keil.

“We need to move our product by truck to serve the energy needs of Californians and the demands of the refineries we supply,” he said.

Exxon reduced oil production from 30,000 to 8,500 barrels a day and is storing the crude in tanks at Las Flores Canyon near the coast highway.

Russell said the company now has two weeks’ worth of storage space left.

A conspiracy involving Gov. Jerry Brown, state regulators, Chevron Corp. and the oil industry let petroleum companies inject their wastewater into California aquifers despite the devastating drought, a lawsuit filed Wednesday alleges.

The suit claims that Brown in 2011 fired California’s top oil regulator under pressure from the industry after she started subjecting some of the oil companies’ operations to greater scrutiny, particularly requests to dispose of oil field wastewater underground. Brown then replaced her with someone who promised to be more “flexible” with the oil companies, according to the complaint.

Federal officials have since determined that oil companies have injected billions of gallons of their wastewater into aquifers that should have been protected by law, aquifers that could be used for drinking or irrigation. California regulators have now pledged to end the practice, although some of the injection wells may be allowed to keep pumping until 2017.

“California is experiencing the greatest drought of this generation, and protecting fresh water is of paramount concern,” said R. Rex Parris, lead attorney representing Central Valley farmers on the suit, which was filed in U.S. District Court for the Central District of California.

California’s oil reservoirs contain large amounts of salty water that must be separated from the petroleum and disposed of, usually by pumping it underground. Oil production companies can’t extract oil without some way of handling the left-over water, also known as “produced water.” The urge to boost California oil production prompted the conspiracy, Parris said.

“The fundamental goal of the … conspiracy was to preserve and expand the ability to inject underground chemicals and toxic waste, thereby expanding their oil production and maximizing profits, including tax revenues,” he said.

The governor’s office declined to comment on the suit Wednesday, as did the state’s oil regulating agency, the Division of Oil, Gas and Geothermal Resources. The division is named as a defendant in the suit, as are Chevron, Occidental Oil, two oil industry associations and several state and local officials. A Chevron spokesman said protecting water resources is one of the company’s core values.

The suit marks the latest twist in a long-building problem that burst into the open last year when the division abruptly shut down several wells that it feared could be injecting oil-field wastewater into aquifers already used for irrigation or drinking. Since then, the number of injection wells closed by the state has increased to 23. But the division insists it has not yet found any drinking or irrigation wells that have been tainted by the injections.

The lawsuit argues, however, that at least one Central Valley farmer lost an orchard to contamination from the oil industry’s produced water. Mike Hopkins, one of the plaintiffs in the suit, had to tear out 3,500 cherry trees whose leaves kept shriveling up and turning brown. Tests of the water showed unusually high levels of salt and boron. A former wastewater injection well lay across a rural road from his Kern County orchard.

Much of the suit involves a 2011 episode that until this year received little attention outside Sacramento and the Central Valley’s oil fields.

Oil companies and their political allies complained that the division under its supervisor at the time, Elena Miller, had bogged down the process of applying for underground injection permits. In addition to wastewater disposal, California oil companies need the permits to inject steam or water into aging oil fields as a way of flushing out more petroleum.

Miller had held the position since 2009 and was considered an outsider by the industry. According to the suit, Miller insisted that the law required oil companies to submit detailed engineering and geological studies for each proposed injection well before the division could issue a permit.

The industry balked and took its complaints directly to the governor, urging Brown to fire Miller. A few Central Valley politicians had already done the same. Some environmentalists, meanwhile, had criticized Miller for what they considered her hands-off approach to hydraulic fracturing.

Chevron spokesman Kurt Glaubitz said Wednesday that the company had not urged Brown to remove Miller.

In November 2011, Brown removed Miller. She was replaced by Tim Kustic, who according to the suit dropped the requirement that the companies submit the disputed studies before receiving injection permits. Kustic is also named as a defendant in the suit.
