When the United Kingdom voted to leave the European Union last month, the seaside town of Port Talbot in Wales eagerly went along with the move. Brexit was approved by some 57 percent of the town's residents.

Now some of them are wondering if they made the wrong decision.

The June 23 Brexit vote has raised questions about the fate of the troubled Port Talbot Works, Britain's largest surviving steel plant — a huge, steam-belching facility that has long been the town's biggest employer.

Next In Line For A Fracking Boom, California Looks At The Rules

Dec 20, 2012
Originally published on December 20, 2012 10:18 pm

The controversial drilling technique known as hydraulic fracturing has created an oil and gas boom around the country. In states like Texas, Pennsylvania and Colorado, there's been heated debate about rules that protect groundwater and public health.

California is now wading into that arena with the release of the state's first fracking regulations. The state's earthquake-prone geology, however, could bring particular concerns.

Fracking itself isn't new. The technology behind it, though, has changed.

"We don't do things the way we used to do them," says Ben Shepperd, who heads the Permian Basin Petroleum Association, a regional trade group in West Texas.

"In the '20s, a frack job was once you drill a hole, you drop TNT down the hole and crack the rock that way. That was an old-fashioned frack job," he says standing next to a towering rig that's drilling a new oil well on the outskirts of Midland.

Fracking technology has come a long way. Oil companies now drill horizontally underground along a layer of oil-saturated shale rock. Then they crack the rock by injecting water mixed with sand and chemicals at high pressure.

The West Texas oil industry went bust 30 years ago, but it's currently booming. Shepperd says companies are spending $1 billion a month on drilling in the region.

Next in line for a fracking boom could be California, which is sitting on one of the largest shale oil resources in the country.

"There's a high degree of public interest in this, a high degree of legislative interest in this," says Jason Marshall of California's Department of Conservation.

The state's newly proposed rules are similar to others' in many ways, he says. Drillers would have to pressure test wells and monitor them during and after fracking. But there are new requirements, like looking for old oil wells around fracking sites that could create leaks. "So we are leading in a number of these areas," he says.

Not everyone agrees. "I think we were late to this game," says Bill Allayaud of the non-profit Environmental Working Group. He says just a few years ago, California state regulators were slow to admit that fracking was going on at all.

"They said we don't need to frack here. We don't need to get gas out of the ground that way," he says. "But it turns out we've been getting oil out of the ground that way for decades."

Drillers weren't required to report fracking to the state, but under the proposed rules, they would be. Regulators would then make that information public online.

But Allayaud says landowners near oil wells would have to keep checking that website, because oil companies wouldn't be required to contact them directly.

"Why not?" he asks. "If this stuff is so safe, you're saying you're not polluting anyone's groundwater, let them know in advance so if they want to do their own water quality testing, more power to them."

Like in other states, drillers would have to say what chemicals are in their fracking fluid — unless it's considered a trade secret. Tupper Hull of the Western States Petroleum Association says that information is propriety.

"There's a reason we protect trade secrets and it's not to benefit oil companies," he says. "It's to benefit consumers and to ensure we've got a very competitive marketplace."

Recently, though, concerned lawmakers in Texas have said their trade secret rule is so heavily used, it's become a loophole.

And then there's one more issue: "It takes a big fault to make a big earthquake," and California has plenty of those, says Mark Zoback, a geophysicist at Stanford University.

The risk of a big earthquake from fracking itself is relatively low. But there could be an issue with the fracking wastewater. Drillers often dispose of it by injecting it underground, which builds up pressure.

"You don't inject into existing faults, especially big ones," Zoback says.

California regulators say the fracking rules don't address that because it's handled in existing wastewater rules, but Zoback says the state will have to increase its scrutiny.

"You know it's not [whether] hydraulic fracturing is good or hydraulic fracturing is bad," he says. It's whether "hydraulic fracturing is safe or hydraulic fracturing is unsafe."

California's geology is so complex, says Zoback, that safety has to be considered on a site by site basis.

You're listening to ALL THINGS CONSIDERED from NPR News.

The technique known as hydraulic fracturing has created an oil and gas boom around the country. And the rapid rise of fracking has state governments grappling with how to regulate it. Well, now California has released its first fracking regulations.

...of fracking has state governments grappling with how to regulate it. Now, California has released its first fracking regulations.

Lauren Sommer of member station KQED in San Francisco reports on how practices around the country have influenced California's new rules.

LAUREN SOMMER, BYLINE: If you've heard anything about hydraulic fracturing, you've probably heard about places like West Texas. Thirty years ago, its oil industry went bust. Now, it's booming.

BEN SHEPPERD: We don't do things the way they used to do it.

SOMMER: Ben Shepperd heads the Permian Basin Petroleum Association, a regional trade group in West Texas. He's standing next to a towering rig that's drilling a new oil well on the outskirts of Midland.

SHEPPERD: In the '20s, a frack job was once you drill a hole, you drop TNT down the hole and crack the rock that way.

SOMMER: Shepperd says fracking technology has come a long way. Now, oil companies drill down and then turn the equipment and drill horizontally along a layer of oil-saturated shale rock. Then they crack the rock by injecting water mixed with sand and chemicals at high pressure. Some of that mixture comes back up with the oil and creates wastewater.

There's a heated debate about regulating this process to protect groundwater and public health. Now, California could be next in line for a fracking boom. The state is sitting on one of the largest shale oil resources in the country, the Monterey Shale.

JASON MARSHALL: There's a high degree of public interest in this, a high degree of legislative interest in this.

SOMMER: Jason Marshall of California's Department of Conservation says the newly proposed rules are similar to other states in many ways. But there are new requirements, like looking for old wells around fracking sites that could create leaks.

MARSHALL: So we are leading in a number of these areas.

BILL ALLAYAUD: I think we were late to this game.

SOMMER: Bill Allayaud is with the nonprofit Environmental Working Group. He says just a few years ago, state regulators were slow to admit that fracking was going on at all.

ALLAYAUD: They said, we don't need to frack here. We don't need to get gas out of the ground that way. But it turns out we've been getting oil out of the ground that way for decades.

SOMMER: Drillers weren't required to report fracking to the state. But under the proposed rules, they would be. Regulators would then post that information online at least three days before fracking takes place.

But Allayaud says landowners near oil wells would have to keep checking that website because oil companies wouldn't be required to contact them directly.

ALLAYAUD: Why not? If this stuff is so safe, let them know in advance so if they want to do their own water quality testing, more power to them.

SOMMER: Like in other states, drillers would have to say what chemicals are in their fracking fluid, unless it's considered a trade secret. Tupper Hull of the Western States Petroleum Association says it's proprietary information.

TUPPER HULL: There's a reason we protect trade secrets, and it's not to benefit oil companies. It's to benefit consumers and ensure that we've got a very competitive marketplace.

SOMMER: The industry makes this argument a lot, so much so that recently concerned lawmakers in Texas have said trade secret claims are so heavily used, it's become a gaping loophole.

And then there's one other issue.

MARK ZOBACK: It takes a big fault to make a big earthquake.

SOMMER: California has plenty of those, says Mark Zoback, a geophysicist at Stanford University. The risk of a big earthquake from fracking itself is relatively low. But there could be an issue with fracking wastewater. Drillers often dispose of it by injecting it underground, which builds up pressure.

ZOBACK: You don't inject into preexisting faults, especially big ones.

SOMMER: California regulators say the fracking rules don't address that because it's handled in existing wastewater rules. But Zoback says the state will have to increase its scrutiny.

ZOBACK: You know, it's not hydraulic fracturing is good or hydraulic fracturing is bad, hydraulic fracturing is safe or hydraulic fracturing is unsafe.

SOMMER: California's geology is so complex, says Zoback, that safety has to be considered on a site-by-site basis.
