California regulators on Thursday closed 33 oil company wells that had injected wastewater into potentially drinkable aquifers protected by federal law.

The new closures bring to 56 the number of oil-field wastewater injection wells shut down by the state after officials realized they were pumping oil-tainted water into aquifers that potentially could be used for drinking or irrigation.

All but two of the latest closures are in Kern County, in California’s drought-stricken Central Valley. One lies in Ventura County, another in northern Los Angeles County. Officials with California’s Division of Oil, Gas and Geothermal Resources spent Friday verifying that they had, in fact, closed. Of the 33, only 21 had been actively injecting wastewater before Thursday.

“This is part of our ongoing effort to ensure that California’s groundwater resources are protected as oil and gas production take place,” said Steven Bohlen, the division’s supervisor.

California’s oil fields contain large amounts of salty water that comes to the surface mixed with the oil. It must be separated from the petroleum and disposed of, often by injecting it back underground. Much of the water is pumped back into the same geologic formation it came from. But enough left-over water remains that companies must find other places to put it.

Fears of contamination

The division, part of California’s Department of Conservation, for years issued oil companies permits to inject their left-over water into aquifers that were supposed to be off-limits, protected by the federal Safe Drinking Water Act.

The problem, detailed in a Chronicle investigation earlier this year, raised fears of water contamination in a state struggling through a historic, four-year drought.

So far, however, no drinking water supplies have been found to be tainted by the injections.

Still, some environmentalists expressed outrage that so few wells had been closed.

The division has identified 178 wells that were injecting into legally protected aquifers with relatively high water quality, defined as those with a maximum of 3,000 parts per million of total dissolved solids. More than 2,000 other wells inject into aquifers that would be harder to use for drinking water, either because they are too salty or because they also contain oil.

“This is too little, too late to protect our water,” said Kassie Siegel, director of the Climate Law Institute at the Center for Biological Diversity. “With each passing day the oil industry is polluting more and more of our precious water.”

The division reported Friday, however, that not all 178 wells required closure. Some had already been shut down by their operators, while others had been converted into wells for extracting oil — not dumping wastewater.

An oil industry trade group noted that all of the wells closed Thursday had received state permits, even if the state now acknowledges that those permits should never have been issued.

“Both regulators and producers are committed to protecting underground water supplies, and today’s announcement reinforces the seriousness of that commitment,” said Catherine Reheis-Boyd, president of the Western States Petroleum Association.

Safeguarding water supplies

“California’s oil and natural gas producers are committed to operating their wells in a manner that continues to safeguard public water supplies,” she said.

Revelations that the division allowed injections into relatively fresh groundwater supplies touched off a political firestorm, triggered lawsuits, and led Bohlen to launch a reorganization of his staff.

More well closures will likely follow. Under regulations adopted this year, wells injecting into aquifers with water quality between 3,000 and 10,000 total dissolved solids must cease injections by Feb. 15, 2017, unless granted an exemption from the federal Environmental Protection Agency.

    Fired regulator: Governor pushed to waive oil safeguards

    Fired regulator: Governor pushed to waive oil safeguards

    SAN FRANCISCO (AP) — California’s top oil and gas regulators repeatedly warned Gov. Jerry Brown’s senior aides in 2011 that the governor’s orders to override key environmental safeguards in granting oil industry permits would violate state and federal laws protecting groundwater from contamination, one of the former officials has testified.

    Brown fired the regulators on Nov. 3, 2011, one day after what the official says was a final order from the governor to bypass provisions of the federal Safe Drinking Water Act and grant permits for oilfield injection wells. Brown later boasted publicly that the dismissals led to a speed up of oilfield permitting.

    In a newly filed court declaration, Derek Chernow, Brown’s former acting director of the state Department of Conservation, also alleged that former Gov. Gray Davis urged fellow Democrat Brown in a phone call to fire Chernow and Elena Miller, the state’s oil and gas supervisor.

    Brown’s spokesman, Evan Westrup, labeled the allegations “baseless.”

    “The expectation – clearly communicated – was and always has been full compliance with the Safe Drinking Water Act,” Westrup said Thursday.

    This year, however, the state acknowledged that hundreds of the oilfield operations approved after the firings are now polluting the state’s federally protected underground supplies of water for drinking and irrigation.

    The U.S. Environmental Protection Agency has given the state until 2017 to resolve what state officials conceded were more than 2,000 permits improperly given to oil companies to inject oilfield production fluid and waste into protected water aquifers. An earlier AP analysis of the permits found state records showed more than 40 percent of those were granted in the four years since Brown took office.

    Chernow’s declaration, obtained by The Associated Press, was contained in an Aug. 21 court filing in a lawsuit brought by a group of Central Valley farmers who allege that oil production approved by Brown’s administration has contaminated their water wells. The lawsuit also cites at least $750,000 in contributions that oil companies made within months of the firings to Brown’s campaign for a state income tax increase.

    Westrup denied the oil companies’ support for Brown’s tax-increase campaign was related to the firings, saying, “the governor’s focus is doing what’s best for California, and that’s what informs his decisions.”

    Robert Stern, former general counsel of the state’s ethics agency and the architect of a 1970s state political reform act, said there was nothing illegal about Brown receiving the oil industry contributions for his tax campaign unless they were explicitly in return for firing the oil regulators.

    Chernow’s statement describes for the first time the alleged back story of the controversial permit approvals. He declined to comment to the AP and Miller did not respond to interview requests.

    Brown’s boasting about the firings to speed up permitting is at odds with his image as a leading proponent of renewable energy and reduced fossil fuel consumption. That reputation led to a recent meeting with Pope Francis to discuss climate change.

    Westrup said an ongoing effort by Brown to reduce consumption of fossil fuels in the state by up to 50 percent and the oil industry’s fight against elements of Brown’s climate-change campaign shows “where the administration stands and what it’s fighting for.”

    The firings occurred as the governor was scrambling to drum up energy sources, jobs and business and to win support for the ultimately successful statewide vote on tax increases to tackle state budget woes.

    Today, with the state in the fourth year of drought and a state of emergency declared by Brown, protecting the adequacy and purity of water supplies for farms and cities is a paramount priority.

    In the declaration in the farmers’ case, Chernow said he and Miller were under intense pressure from the oil industry as well as the Brown administration to relax permitting standards for injection wells that oil companies use to pump production fluid and waste underground.

    Chernow testified he was in the office of John Laird, Brown’s secretary of Natural Resources, in early October 2011 when Laird took a call from Brown. Laird told Chernow that Brown said he had just received a call from Davis, then acting as legal counsel for Occidental Petroleum, the country’s fourth-biggest oil Company.

    Brown said Davis and Occidental had demanded Brown fire Chernow and Miller over what Occidental complained was the slow pace of issuing drilling permits, according to Chernow.

    Davis declined to comment Thursday.

    A few weeks later, on Nov. 2, 2011, Chernow and Miller received a call from Brown’s energy adviser, Cliff Rechtschaffen, who urged the regulators to “immediately fast-track” approval of new oilfield permits, according to Chernow’s filing.

    Miller replied that what Brown aides and the oil industry were pressing for “violated the Safe Drinking Water Act, and that the EPA agreed” with that conclusion, Chernow said. In response, according to Chernow, Rechtschaffen told them “this was an order from Governor Brown, and must be obeyed.”

    Chernow and Miller were fired the following day.

    Memos sent to Department of Conservation staff the next month – obtained through state public records laws by lawyers for the farmers – allegedly detail some ways state oilfield regulators were told they could now bypass some federally mandated environmental reviews and approve permits.

    The state, under increasing pressure from the EPA, this year and last ordered the shutdown of 23 improperly permitted oilfield wells posing the most immediate threat to nearby water wells.

    Current officials in the Department of Conservation said they believe the actual number of flawed permits granted under Brown is lower than the 46 percent the state records show, but they have not provided alternate figures.

    The state improperly issued permits, they said, because of misunderstandings and poor record-keeping, rather than willful decisions by Brown’s administration.

    The safeguards at issue in the alleged permitting dispute were a “very fundamental” part of the federal Safe Drinking Water Act’s protections against oilfield contamination, said David Albright, manager of the EPA’s California groundwater office, this week.

    California “has a huge amount of work to do” to bring its regulation of oilfield injection wells into compliance with federal law, said Jared Blumenfeld, the regional EPA administrator in California. Blumenfeld cited a “sea change” over the past year in state compliance efforts, however.

    Executives of Occidental and Aera Energy at the time thanked Brown for his involvement in the oilfield permitting process, as Occidental CEO Steven Chazren noted in a January 2012 call with financial analysts, two months after top regulators were fired.

    That month, Occidental became the first major oil company to come out in support of the Brown’s tax measure and donated the first of $500,000 to Brown’s campaign for the tax referendum. A month later, Aera donated $250,000.

    Margita Thompson, a spokeswoman at what is now the independent California spin-off of Occidental, California Resources Council, said that all the farmers’ allegations were “wholly without merit.” Cindy Pollard, spokeswoman for Aera, said the company often donates to revenue-raising state campaigns. “Aera’s contributions were not quid pro quo,” she said.

      Exclusive: Pennsylvania Family Dealing with Water Contamination Linked to Fracking Industry

      The Chichura family has flammable well water, most likely due to a fracking job gone wrong in Pennsylvania’s Susquehanna County. Their water well, along with those of four of their neighbors, was allegedly contaminated with methane in the fall of 2011, shortly after Cabot Oil started drilling operations near their home.

      The Pennsylvania Department of Environmental Protection (DEP) confirmed the Chichuras had methane in their water on September 21, 2011, and advised them to equip their well with a working vent to avoid a possible ignition.

      The contamination of wells is not an anomaly. The DEP identified 245 sites potentially contaminated by the fracking industry between 2008 and 2014.  …(continued)

      Texas Family’s Water Well Explodes, Burns 4-Year Old, Father and Grandfather — and Fracking to Blame, Lawsuit Alleges

      A family in Texas, including a four-year old, her parents and her grandfather, were severely burned when their water well ignited into a massive fireball after methane from nearby fracked wells contaminated their water supply, a newly filed lawsuit against EOG Resources and several related companies alleges.

      Cody Murray, a 38-year old who previously worked in the oil and gas industry, suffered burns to his face, arms, neck and back that were so severe that he was left permanently disabled, no longer able to drive because the nerve damage has left him unable to grip steering wheels or other objects. Cody’s young daughter, who was over 20 feet away from the pump house when it ignited, suffered first and second degree burns, as did Jim Murray, Cody’s father.

      The cause of the blast? Nearby fracked wells, the lawsuit alleges.  …(continued)

        CCST Report: Fracking pollution poses major risks

        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.”

        Report: Fracking Risk to CA is Aquifer Contamination, Not Quakes

        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.
