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.

    KQED: Routes revealed for BNSF trains hauling volatile crude oil in California

    Repost from KQED Science
    [Editor: Of great interest for many in California, but lacking any comment on the Union Pacific rail line that transports freight to Benicia and over the Benicia Bridge to Contra Costa County and the East Bay.  Latest on the Union Pacific line as of 6/27/14: The Riverside Press Enterprise reports that “Union Pacific submitted a letter May 29 to the state office, saying the company was “compiling and reviewing the data.”  – RS]

    Revealed: Routes for Trains Hauling Volatile Crude Oil in California

    State officials have released routing information for trains carrying a volatile grade of crude oil through California.

    The newly released information reveals that tank cars loaded with oil from the Bakken formation, a volatile crude that has a history of exploding, rumble through downtown Sacramento and through Stockton about once a week. Before they get there, they travel along the Feather River, a major tributary of the Sacramento and a key source of drinking water. They pass through rural Northern California counties — Modoc, Lassen, Placer, Plumas, Yuba and Butte — before reaching their destination in Contra Costa County.

    This is the first time that information about the trains’ routing in California and their frequency has been made public. About once a week, a Burlington Northern Santa Fe (BNSF) train enters the state from Oregon, headed for the Kinder Morgan rail yard in Richmond. Each train is carrying a million gallons or more of Bakken crude.

    “The purpose of the information is really to give first responders better awareness of what’s coming through their counties,” says Kelly Huston, a deputy director at the Governor’s Office of Emergency Services.

    The notifications (shown below) provided by BNSF to the state list the counties through which the trains pass, and the average number of trains per week. They’re retrospective, reporting what’s already happened, rather than looking ahead to what trains could be coming.

    “Right now the information, because it’s not very specific, is being used as an awareness tool,” said Huston.

    An emergency order issued by the federal Department of Transportation requires railroads to notify emergency responders about large shipments of Bakken crude. BNSF had asked the OES to sign a non-disclosure agreement, which state officials refused to do. After keeping the notifications secret from the public for a few weeks, the state decided to release them on Wednesday, following the lead of other states that had already done so.

    “We think it is very important that those responsible for security and emergency planning have such information to ensure that proper planning and training are in place for public safety,” Roxanne Butler, a spokeswoman for BNSF, wrote in an email. “But we also continue to urge discretion in the wider distribution of specific details.”

    The DOT issued the order after a series of fiery derailments involving Bakken crude in Alabama, North Dakota and Virginia, among other states. Last July, a train carrying oil from the Bakken exploded in a town in Quebec, killing 47 people.

    “We want the rail companies to do everything they can to ensure public safety,” said Diane Bailey of the Natural Resources Defense Council. She says there are three things that would help assuage her concerns: safer rail cars, slower speed limits, and making sure the trains are always staffed.

    Butler said the railroads themselves have also pushed to phase out the DOT-111 railcars that have been involved in the accidents. “The rail industry also implemented a number of additional safety operating practices several months ago to reduce the risk of moving crude by rail,” she wrote, “including lower speed limits and had addressed the train securement issue in August of 2013 as part of the Federal Railroad Administration’s emergency order.”

    California lawmakers have introduced bills that would provide more money for oil spill response, and require more information from railroads about hazardous materials. The recently-passed California budget includes a fee on oil entering California by rail, which would help fund the state’s Office of Oil Spill Prevention and Response. It also provides more money to the California Public Utilities Commission for rail safety inspectors.

    Transporting crude oil by rail is a burgeoning business, thanks to an oil boom in North Dakota. In 2013, more than 6 million barrels of crude oil came into California by rail. In 2008, there were none.
