In California, Farmers Rely on Oil Wastewater to Weather Drought

The wet, white noise of gushing water rises above a background track of twangy guitar. Water is tumbling out of a pipe into a holding pond that looks as though it has sat nearly empty for ages, its sandy sides the color of parched desert. It looks like the California of recent headlines: drought so bad the ground is blowing away. Except now, here, in this promotional video for Chevron, there is water. Lots of it.

“The sound of that water is music to my ears,” David Ansolabehere, the general manager of the Cawelo Water District in Kern County, says in the video, gazing out over the rapidly filling pond. “Chevron is being environmentally conscious, and this is a very beneficial program, and it’s helped a lot of our farmers, helped our district, tremendously.”

The oil fields of Kern County, where Chevron is the largest producer, pump out more oil than those of any other county in the United States. It also happens to be one of the country’s most prolific agricultural counties, producing over $6 billion in crop value every year. But after three years of strangling drought, all that agriculture is on life support.

That’s where Chevron comes in. For every barrel of oil Chevron produces in its Kern River oil field, another 10 barrels of salty wastewater come up with it. So Chevron is selling about 500,000 barrels of water per day, or 21 million gallons, back to the Cawelo Water District—the local water district that delivers water to farmers within a seven-mile slice of Kern County—at an undisclosed amount, but “essentially ‘at cost,’” according to Chevron spokesman Cameron Van Ast. In a time when freshwater in the Central Valley is selling at up to 10 times the typical cost, it’s a good deal for farmers.

The wastewater Chevron is selling flows, without municipal treatment (though the oil products are removed), to 90 local farmers who spread it on their citrus, nut and grape crops. The Cawelo Water District might first mix the wastewater with freshwater, or it might not, depending on what crop the wastewater will be used on—and on how much freshwater is available at the time. In the midst of a drought, there is less freshwater, so the water the farmers get is saltier than in a wet year. But the farmers understand that using the salty wastewater on their crops is an emergency measure. If all goes as planned, when the rains come back the excess salt will be flushed through the soil.

But it’s a risky dance; over time, high sodium can change the properties of the soil, making it impermeable, unable to take in any more water. Trees would start to get “salt burn.” Their leaves would turn yellow, and yields would decline. Eventually, the soil becomes barren.

Ansolabehere says the wastewater mixture sent to farmers is rigorously monitored to keep from salting the soil to that degree. It is tested quarterly for salts and boron, he says. “The only reason this program works is because [Chevron’s] production water is of very good quality,” he says. “So maybe we’ll have a little salt buildup. But the next rain will flush it out.”

But the National Weather Service doesn’t foresee much rain in the immediate future. In fact, drought conditions may “intensify.”

For local farmers, dwindling water is a noose slowly tightening. Most take relief wherever they can get it, but not Tom Frantz. “I would rather let my trees die” than use the Chevron water, he says. Frantz is a small-time almond farmer who lives about six miles from the oilfields where the wastewater is pumped into mixing basins. His 36 acres are a speck in the shadow of much larger operations; vast orange groves, pistachio trees, rows and rows of almond trees. But Frantz knows farming. He’s been in Kern County, just west of the town Shafter, for all of his 65 years. His grandparents were farmers a few miles away. His parents farmed, too. There’s a generation below him, he says, who look as if they’ll take it up soon.

In normal years, Frantz depends on groundwater pumped from wells, as well as “surface water,” the water held in municipal reservoirs that flows in frigid streams from the melting snowpack in the Sierra Nevada mountains. But with the Sierra snowpack this winter at a paltry 6 percent of its typical heft, there won’t be much to melt. Chevron’s wastewater is an option, but Frantz knows what all farmers know: You can’t grow food with salty water for very long.

“It’s just not sustainable at all to use salty water, no matter how much you dilute it…. We can farm here a long time, if we’re careful about the salts that we apply,” he says. “I’ve seen the farms that have saltier groundwater, and they have severe difficulties after 50 years. That’s very low levels of salts that’ll do that.”

Frantz has little confidence in how oil industry wastewater is regulated in his area, and he is concerned by what still isn’t known about the contents of the wastewater. Recently, there was a scandal over news that state oil and gas officials for years let oil companies inject drilling and fracking wastewater into hundreds of wells in protected aquifers. The water was laden with the benzene, a carcinogen, according to a Los Angeles Times investigation. “What it shows me is that we have to look out for ourselves,” Frantz says.

California doesn’t have statewide regulations for recycling wastewater for agriculture. Instead, nine regional water boards issue permits to local water districts. Once a year, the Cawelo Water District is required to send data about the salt and boron content to the Central Valley Water Board, according to Clay Rodgers, the board’s assistant executive officer. But the district isn’t obligated to test for other components, like heavy metals, arsenic, radioactive materials and chemicals that might be used in the drilling process. Ansolabehere says Cawelo has tested for radioactive elements “a couple of times” over the past 20 years, since “it’s very expensive” to test for, and it isn’t required by the board. Those tests have not turned up any positive results.

Chevron, for its part, says testing last month showed no heavy metals or chemical toxins were present in the water above maximum allowable levels. The arsenic levels were high, however, but “issues related to the arsenic concentrations in the water were fully addressed in the process of obtaining the permit from the Central Valley Regional Water Quality Control Board,” Chevron said in a statement. “Protection of people and the environment is a core value for Chevron, and we take all necessary steps to ensure the protection of our water resources.”

The Central Valley Regional Water Quality Control Board came to the conclusion that the high arsenic in the waste water was acceptable because most of the arsenic appeared in models to get “tied up” in the soil as it made its way down to the water table, says Rodgers. In other words, the Board sees no threat of tainting the groundwater with arsenic, because it largely stays in the soil. But no monitoring is in place to see if that arsenic is building up to unsafe levels in the agricultural soils themselves.

Little to no independent scientific research has been done on this type of water and how it interacts with crops, soil and surrounding bodies of water. Some scientists say there are too many unknowns associated with the wastewater from oilfields. If it is being used on food, and to irrigate land that lies above drinking water aquifers, we need to know more about it, they say—especially in light of the fact that, as Rodgers notes, the Central Valley hopes to expand its use for farm irrigation during the drought.

“There might not be a single risk out there with this practice. But the biggest risk that we have right now is that we just don’t know,” says Seth Shonkoff, an environmental public health scientist and a visiting scholar at the University of California, Berkeley. “So until we know, we definitely have reason for concern. We know that there are compounds being put down oil and gas wells that you would not want in your food.”

To Shonkoff’s knowledge, no scientist has ever published a study on what compounds from the oil development process—examples he gives are methanol, biocides and surfactants—might be in oilfield wastewater used on crops. Chevron says these constituents are kept separate from the water delivered to farmers.

Avner Vengosh, a Duke University geochemist, is serving on an expert panel for the U.S. Geological Survey while it begins to look into the quality of produced oil-field water from Kern County. His data are “only preliminary,” but he has found “high levels of vanadium, chromium and selenium” in the samples of wastewater he has tested (although he was unable to say if the water was produced from Chevron’s operations or another of the many operators in the area). Those levels are consistent with data from oil- and gas-produced water from other basins in the U.S., according to Vengosh.

Vanadium, a metal, is classified as “possibly carcinogenic” by the International Agency for Research on Cancer. Certain forms of chromium and selenium, both heavy metals, are associated with myriad health problems, including cancer, from chronic high exposure. Ansolabehere says the Cawelo Water District tested for chromium and selenium once, last year, and found none. It has never tested for vanadium. None of these metals are required to be tested for by the Central Valley Water Board.

Could the crops be absorbing these metals? The California Department of Food and Agriculture says it doesn’t have the jurisdiction to look. The Central Valley Water Board doesn’t sample crop residues where the water is used, either.

For Vengosh, what is most worrisome is the possibility that the water is seeping through the farmland into the water table. “It would end up in underlying groundwater. If the groundwater is moving to a drinking water source, you would end up with that in the drinking water eventually,” he says.

No matter how tough the drought gets, Frantz says, he won’t be taking the Chevron water. “It just doesn’t make sense to ruin something,” he says. “To get through years like this, we have to take some land out of production.”

But for Roy Pierucci, a farmer who manages a 160-acre pistachio farm that falls within the Cawelo Water District, the unknowns about the Chevron water won’t deter him from using it. If the water contains some as of yet unknown elements, “it would be a risk we’d be willing to take,” he says, without hesitation. He’s been using the Chevron water for 10 years and has never seen a problem with his crops. (Pierucci was featured in the Chevron promotional video, though he wasn’t paid for the appearance—he says he participated because he values what the company does for the water district.)

“I’ve really never asked what the analysis of the water is. I just know it’s available. There hasn’t been any complaints about it. I don’t think they recommend drinking it,” Pierucci says. “If [the drought] keeps up year after year, I think it would be a concern. I think the salt levels would be higher. They blend it for a reason.”

The Chevron water is vital to Pierucci’s operation, but it isn’t a game changer. “It’s not going to save us,” he says. Three years of brutal drought have left his pistachio trees teetering on the edge of survival. If the drought persists another two or three years, he says, he’ll have to start ripping out his trees and reducing the number of acres he irrigates. On another property he manages, where there is no pumping well on-site, he imagines he’ll be pulling out trees within a year. “You can’t chase water forever. Sooner or later you’re going to lose.”

Crude oil train shipments dwindle in California, for now

Crude oil train shipments dwindle in California, for now

A year ago, California officials nervously braced for an influx of milelong trains carrying volatile crude oil to refineries in the Valley and on the coast – trains similar to the one that exploded two years ago in Canada, killing 47 people.

The trains never arrived. Although tank cars full of oil now roll daily through cities in the Midwest and East, provoking fears of crashes and fires, the number of oil trains entering California has remained surprisingly low, state safety regulators say, no more than a handful a month. In recent weeks, they appear to have dwindled to almost nothing.

The reasons appear to be mainly economic.

“Crude oil shipments from out of state have virtually stopped,” said Paul King, rail safety chief at the California Public Utilities Commission. “Our information is that no crude oil trains are expected for the rest of this month.”

Most notably, the BNSF Railway recently stopped running a 100-car train of volatile oil from the Bakken region of North Dakota through the Feather River Canyon and midtown Sacramento to the Bay Area. The trains, several a month, carried an estimated 3 million gallons of fuel each.

Bakken oil, a lighter type of crude, similar to gasoline, has gained a fearsome reputation since it entered the national scene a few years ago. A string of Bakken train explosions around the country prompted the federal government to issue a warning last year about the oil’s unusual volatility and launch efforts to write stiffer regulations on rail transport, including a proposal to require sturdier tank cars for oil.

Two more Bakken train derailments and explosive fires recently in West Virginia and Illinois triggered a new round of complaints that the federal government is dragging its heels in finalizing those regulations.

The BNSF train through Sacramento was believed to be the only train in California carrying 100 cars of Bakken oil. PUC rail safety deputy director King said his commission’s rail monitors have been told by owners of a Richmond oil transfer station in the Bay Area that refiners stopped the shipments in November as global oil prices dropped.

California Energy Commission fuels specialist Gordon Schremp said lower prices for other types of oil have made Bakken marginally less marketable in California, although that could easily change in the future.

Other projects, like a Valero Refining Co. plan to run two 50-car oil trains daily through Sacramento beginning this spring to its Benicia plant, have not yet gotten off the ground, in part because of political opposition. Under pressure from state officials, including Attorney General Kamala Harris, Benicia recently announced it is redoing part of its environmental and risk analysis of the Valero rail project. Valero has said it intends to ship lighter fuels, but has declined to say whether those will be Bakken.

State safety officials said the slowdown provides a bit more time to provide hazardous-materials training for more firefighters, as well as to put together a state rail-bridge inspection program and to upgrade disaster and waterway spill preparedness. But state officials said they still feel like they’re playing catch-up as they prepare for existing and future potential rail hazards.

“This apparent reprieve may seem helpful, but we still have substantial amounts of … hazardous materials traveling across California’s rail lines,” said Kelly Huston, deputy director of the state Office of Emergency Services. “It only takes one train to create a major disaster.”

Oil prices have begun rising again, and state officials say they expect Bakken shipments to Richmond and potentially elsewhere to be back on track at some point. “We don’t have any concrete info about when it will resume,” the PUC’s King said. “When prices come up, it is likely to resume, and that could be in months.”

Federal emergency rules require railroads to report to states when they run trains carrying more than 1 million gallons of Bakken crude, and then again when that amount changes by 25 percent or more. BNSF sent the state Office of Emergency Services a brief notice on Wednesday acknowledging it had not shipped more than 1 million gallons of Bakken on any train in the last week. The notice does not say how long ago the shipments stopped or when they may resume.

BNSF officials have contended in letters to the state that shipping information is proprietary and should be kept secret. A BNSF spokeswoman declined this week to discuss shipments with The Sacramento Bee, writing in an email, “Information regarding hazardous material shipments is only provided to emergency responders.”

King of the PUC said his monitors estimate that eight or more non-Bakken crude oil trains had been entering the state monthly from Canadian and Colorado oil fields recently, headed to refineries or transfer stations. The Canadian oil, called tar sands, is not considered as explosive as Bakken, but two tar-sands trains derailed and exploded in recent weeks in Ontario, creating fires that lasted several days.

The national concern about crude oil rail shipments follows a boom in domestic oil production, notably in North Dakota, where hydraulic-fracturing advances have freed up immense deposits of shale oil. Lacking pipeline access, North Dakota companies have turned to trains to ship the oil mainly to East and Gulf Coast refineries and to Washington state. Crude by rail shipments in the United States skyrocketed from 9,500 carloads in 2008 to 436,000 in 2013, according to congressional data.

California continues to produce a sizable amount of its own oil in Kern County and receives marine shipments from Alaska and foreign sources. Still, a recent state energy-needs analysis estimates the state could receive as much as 23 percent of its oil via train or barge from continental sources, including North Dakota, Canada, Texas and other Western states, in the coming years. That estimate is based on plans by refineries in Benicia, San Luis Obispo and Kern County to build rail facilities that can accommodate large crude transports.

Hundreds of illicit oil wastewater pits found in Kern County

Hundreds of illicit oil wastewater pits found in Kern County

Water officials in Kern County discovered that oil producers have been dumping chemical-laden wastewater into hundreds of unlined pits that are operating without proper permits.

Inspections completed this week by the Central Valley Regional Water Quality Control Board revealed the existence of more than 300 previously unidentified waste sites. The water board’s review found that more than one-third of the region’s active disposal pits are operating without permission.

The pits raise new water quality concerns in a region where agricultural fields sit side by side with oil fields and where California’s ongoing drought has made protecting groundwater supplies paramount.

Clay Rodgers, assistant executive officer of the water board’s Fresno office, called the unregulated pits a “significant problem” and said the agency expects to issue as many as 200 enforcement orders.

State regulators face federal scrutiny for what critics say has been decades of lax oversight of the oil and gas industry and fracking operations in particular. The Division of Oil, Gas and Geothermal Resources has admitted that for years it allowed companies to inject fracking wastewater into protected groundwater aquifers, a problem they attributed to a history of chaotic record-keeping.

“The state doesn’t seem to be willing to put the protection of groundwater and water quality ahead of the oil industry being able to do business as usual,” said Andrew Grinberg of the group Clean Water Action.

The pits — long, shallow troughs gouged out of dirt — hold water that is produced from fracking and other oil drilling operations. The water forced out of the ground during oil operations is heavily saline and often contains benzene and other naturally occurring but toxic compounds.

Regional water officials said they believe that none of the pits in the county have linings that would prevent chemicals from seeping into groundwater beneath them. Some of the pits also lack netting or covers to protect migrating birds or other wildlife.

Currently, linings for pits are not required, though officials said they will consider requiring them in the future. Covers are mandated in some instances.

The pits are a common site on the west side of Bakersfield’s oil patch. In some cases, waste facilities contain 40 or more pits, arranged in neat rows. Kern County accounts for at least 80% of California’s oil production.

The facilities are close to county roads but partially hidden behind earthen berms. At one pit this week, waves of heat rose from newly dumped water, and an acrid, petroleum smell hung in the air.

Rodgers said Thursday that the agency’s review found 933 pits, or sumps, in Kern County. Of those, 578 are active and 355 are not currently used.

Of the active pits, 370 have permits to operate and 208 do not. All of the pits have now been inspected, he said.

The possible existence of hundreds of unpermitted pits came to light when regional water officials compared their list of pit operators to a list compiled by the Division of Oil, Gas and Geothermal Resources. The oil regulator’s list contained at least 300 more waste pits than water officials had permitted, Rodgers said.

His staff began inspecting the wastewater sites in April. Initial testing of water wells has not revealed any tainted water, he said.

The pits are an inexpensive disposal method for an enormous volume of water that is forced out of the ground during drilling or other operations, such as fracking. Rodgers said that just one field, the McKittrick Oil Field, produces 110,000 barrels of wastewater a day. According to figures from 2013, oil operations in Kern County produce 80 billion gallons of such wastewater — an amount that if clean would supply nearly a half-million households for a year.

More than 2,000 pits have been dredged over decades of oil operations in Kern County, according to water board records. Oil field companies have not always properly disposed of water, Rodgers said. As recently as the 1980s, it was customary to dump wastewater into drainage canals that line the San Joaquin Valley’s agricultural fields.

But using unlined pits to dispose of wastewater is becoming less common. Some states ban the practice, and many in the oil and gas industry do not consider it effective.

The water board’s long-term plan to address the problem includes requiring remediation of some abandoned pits so that contaminants left behind don’t pollute the air, Rodgers said.

In pits located near clean water sources, Rodgers said, operators will be required to install monitor wells to test water quality. The companies will pay for the testing and provide the results to water officials.

The water board will publish a series of general orders that he said will more tightly control the operation of wastewater pits.

“Our goal is to protect water quality,” Rodgers said. “Our goal is not to shut anybody down, but by the same token, they do not own the waters beneath them. Those waters are for the public good.”

The Fight to Stop a Boom in California’s Crude by Rail

The Fight to Stop a Boom in California’s Crude by Rail

By Tara Lohan, 01/08/2015

Ed Ruszel’s workday is a soundtrack of whirling, banging, screeching — the percussion of wood being cut, sanded and finished. He’s the facility manager for the family business, Ruszel Woodworks. But one sound each day roars above the cacophony of the woodshop: the blast of the train horn as cars cough down the Union Pacific rail line that runs just a few feet from the front of his shop in an industrial park in Benicia, California.

Most days the train cargo is beer, cars, steel, propane or petroleum coke. But soon, two trains of 50 cars each may pass by every day carrying crude oil to a refinery owned by neighboring Valero Energy, which is hoping to build a new rail terminal at the refinery that would bring 70,000 barrels a day by train — or nearly 3 million gallons.

And it’s a sign of the times.

Crude-by-rail has increased 4,000 percent across the country since 2008 and California is feeling the effects. By 2016 the amount of crude by rail entering the state is expected to increase by a factor of 25. That’s assuming the industry gets its way in creating more crude-by-rail stations at refineries and oil terminals. And that’s no longer looking like a sure thing.

Valero’s proposed project in Benicia is just one of many in the area underway or under consideration. All the projects are now facing public pushback–and not just from individuals in communities, but from a united front spanning hundreds of miles. Benicia sits on the Carquinez Strait in the northeastern reaches of the San Francisco Bay Area. Here, about 20 miles south of Napa’s wine country and 40 miles north of San Francisco, the oil industry may have found a considerable foe.

A recent boom in “unconventional fuels” has triggered an increase in North American sources in the last few years. This has meant more fracked crude from North Dakota’s Bakken shale and diluted bitumen from Alberta’s tar sands.

Unit trains are becoming a favored way to help move this cargo. These are trains in which the entire cargo — every single car — is one product. And in this case that product happens to be highly flammable.

This is one of the things that has Ed Ruszel concerned. He doesn’t think the tank cars are safe enough to transport crude oil in the advent of a serious derailment. If a derailment occurs on a train and every single car (up to 100 cars long) is carrying volatile crude, the dangers increase exponentially. In 2013, more crude was spilled in train derailments than in the prior three decades combined, and there were four fiery explosions in North America in a year’s span, the worst being the derailment that killed 47 people and incinerated half the downtown in Lac Megantic, Quebec in July 2013.

Public Comments

In Benicia, a Draft Environmental Impact Report (DEIR) regarding the Valero project was released in June 2014 and promptly slammed by everyone from the state’s Attorney General Kamala Harris to the local group Benicians for a Safe and Healthy Community because it left out crucial information and failed to address the full scope of the project.

One of the biggest omissions in Valero’s DEIR was Union Pacific not being named as an official partner in the project. With the trains arriving via its rail lines, all logistics will come down to the railroad. Not only that, but the federal power granted to railroad companies preempts local and regional authority.This preemption is one of the biggest hurdles for communities that don’t want to see crude-by-rail come through their neighborhoods or want better safeguards.

The DEIR also doesn’t identify exactly what kind of North American crude would be arriving and from where. Different kinds of crude have different health and safety risks. Diluted bitumen can be nearly impossible to clean up in the event of a spill and Bakken crude has proved more explosive than other crude because of its chemical composition. It’s likely that some of the crude coming to Valero’s refinery would be from either or both sources.

Public comments on the DEIR closed on Sept. 15, and now all eyes are on the planning department to see what happens next in Benicia.

But the Valero project is just the tip of the iceberg in California.

In nearby Pittsburgh, 20 miles east of Benicia, residents pushed back against plans from WestPac Energy. The company had planned to lease land from BNSF Railway and build a new terminal to bring in a 100-car unit train of crude each day. The project is currently stalled.

But Phillips 66 has plans for a new rail unloading facility at a refinery in Nipomo, 200 miles south of the Bay Area in San Luis Obispo County, that would bring in five unit trains of crude a week, with 50,000 barrels per train.

Further south in Kern County in the heart of oil country, Plains All American just opened a crude by rail terminal that is permitted for a 100-car unit train each day. Another nearby project, Alon USA, received permission from the county for twice as much but is being challenged by lawsuits from environmental groups.

Closer to home, unit trains of Bakken crude are already arriving to a rail terminal owned by Kinder Morgan in Richmond. Kinder Morgan had been transporting ethanol, but the Bay Area Air Quality Management District allowed Kinder Morgan to offload unit trains of Bakken crude into tanker trucks.

With all this crude-by-rail activity, some big picture thinking would be helpful. As Attorney General Kamala Harris wrote about the Benicia project, “There’s no consideration of cumulative impacts that could affect public safety and the environment by the proliferation of crude-by-rail projects proposed in California.”
