I agree with John Derrig’s letter of Feb. 10, saying we need to stop burning fossil fuels: “Leave it in the ground, OK?” This is what the world’s best climate scientists are telling us we must do to avoid “catastrophic” climate change (IPCC). But how, exactly, do we make a fast, smooth transition to clean energy?
There’s a simple, realistic solution to global warming, which will also be good for our economy: A win-win. Most major economists support it, including eight Nobel Prize winners.
It uses conservative, free-market principles, not government regulations, and it’s revenue-neutral. It won’t hurt consumers or taxpayers.
We can put an increasing carbon pollution fee on all fossil fuels, that’s returned, 100 percent, to every American, every month in equal amounts. As fossil fuels become increasingly more expensive than clean energy, people will use their carbon fee rebate to buy renewables. Middle-class and lower-income Americans will come out ahead financially.
And recent REMI report projects this would create 2.8 million U.S. jobs and increase GDP $75-80 billion annually.
It’s worked in British Columbia for six years. The Economist has pronounced it “A success” (“The Evidence Mounts” July 31. 2014).
The United States can tax imports from China and other carbon polluters to make them cut emissions. Return that import tax money to all Americans, and we can afford products made in the United States.
Federal study: Oklahoma more at risk of big damaging quakes because of increase in small ones

SAN JOSE, California (AP) — Small earthquakes shaking Oklahoma and southern Kansas daily and linked to energy drilling are dramatically increasing the chance of bigger and dangerous quakes, federal research indicates. This once stable region is now just as likely to see serious damaging and potentially harmful earthquakes as the highest risk places east of the Rockies such as New Madrid, Missouri, and Charleston, South Carolina, which had major quakes in the past two centuries. Still it’s a low risk, about a 1 in 2,500 years’ chance of happening, according to geophysicist William Ellsworth of the U.S. Geological Survey. “To some degree we’ve dodged a bullet in Oklahoma,” Ellsworth said after a presentation to the American Association for the Advancement of Science. But, he added, “This is not to say we expect a large earthquake tomorrow.” During the 90-minute session on human-induced earthquakes, three quakes larger than 3.1 magnitude hit northern Oklahoma. Federal records show that since Jan. 1, Oklahoma has had nearly 200 quakes that people have felt. These quakes started to increase in 2008 and made dramatic jumps in frequency in June 2013 and again in February 2014, Ellsworth said. They are mostly in areas with energy drilling, often hydraulic fracturing, a process known as fracking. Many studies have linked the increase in small quakes to the process of injecting wastewater deep underground because it changes pressure and triggers dormant faults. Until now, those quakes were mostly thought of as nuisances and not really threats. But Ellsworth’s continuing study, which is not yet published, showed the mere increase in the number of tiny temblors raises the risk of earthquakes that scientists consider major hazards. That’s generally above a magnitude 5 with older buildings and a magnitude 6 for modern ones, Ellsworth said. “The more small earthquakes we have it just simply increases the odds we’re going to have a more damaging event,” Ellsworth said. A 2011 earthquake in Prague, Oklahoma, was a 5.7 magnitude, causing some damage and hurting two people. Some studies said that was a side effect of the drilling process, but other scientists are not convinced. Experts at the science session said Ellsworth’s finding of a higher risk for big quakes makes sense. “We are worried about this, no question about it,” said Rex Buchanan, interim director of the Kansas Geological Survey. Not all states with fracking and wastewater injections are seeing increased quakes and not all those with increased quakes, such as Texas and Ohio, are at a higher risk for major quakes, Ellsworth said. Arkansas and Ohio, for example, are also now seeing fewer man-made quakes, he said. Much depends on geology and how the wastewater is injected, said Stanford University geophysics professor Mark Zoback. He said industry and regulators can be smarter about where they inject wastewater and where they do not, and can avoid many of these problems.
State plan gives firms until Oct. 15 to stop injecting tainted water

Oil companies in California must stop injecting wastewater from their operations into potentially drinkable aquifers by Oct. 15, according to a plan by state regulators who allowed it to happen for years.
In a proposal submitted to the federal Environmental Protection Agency, regulators promised to painstakingly review wells at risk of contamination, ensuring the injections did not taint aquifers already used for drinking water or irrigation in the drought-plagued Central Valley.
The plan — from California’s Division of Oil, Gas and Geothermal Resources — comes in response to revelations that, for decades, the division granted oil companies permits to inject leftover water from their operations into aquifers that the federal government wanted protected. Now, with California heading into a fourth year of drought, that water may be difficult for humans to use.
A Chronicle analysis found that the state allowed oil companies to drill 171 wastewater injection wells into aquifers that could have been tapped for crops or people. Of those wells, 140 are still in use, according to the division. Injection into those wells must stop by mid-October unless specifically approved by the EPA, according to the plan.

February deadline
An additional 253 wells breached lower-quality aquifers still considered off-limits by the EPA, from which water could have been used with more extensive treatment. Oil companies must cease using these wells by Feb. 15, 2017, barring an exemption from the EPA.
The EPA, which helped uncover the practice in 2011, had given the division until Feb. 6 to submit plans for fixing the problem. The EPA has threatened to seize control of regulating the oil industry’s underground injection wells in California if the state doesn’t do a better job protecting groundwater supplies from contamination. (Although the division’s plan is dated Feb. 6, it was released to the public on Monday.)
“Our goal is to make sure the state is up to the job,” said Jared Blumenfeld, regional administrator for the EPA, in an interview before the division submitted its plans. “Frankly, if it got to the level where we needed to take (control) back, we would. That’s never been off the table. But I think we’re fairly far from needing to do that.”
The time frame for reform has already drawn fire from environmentalists. But both state and federal regulators say the oil industry will need time to comply. If the division is forced to shut down some wells to protect drinking water supplies, the oil companies will have time to find other ways to deal with the waste.
“This is a problem that we worked ourselves into over 30 years, and it’s not a problem that can be solved in a year,” said the division’s new supervisor, Steven Bohlen, appointed by Gov. Jerry Brown last year.
Problem’s roots
The problem dates to 1983, when the EPA gave the division authority to enforce the federal Safe Drinking Water Act in California’s oil fields.
The state’s oil reservoirs typically contain large amounts of briny water mixed with the crude. Companies must separate the oil from the water and get rid of the water, which is usually too laden with minerals and hydrocarbons to be used for drinking and irrigation. In addition, oil-extraction techniques such as hydraulic fracturing use freshwater that becomes tainted in the process and needs disposal .
Companies inject much of the leftover water back into oil reservoirs. But some of it is pumped into salty underground aquifers that have no oil.
The 1983 agreement listed by name aquifers that the oil industry would be able to use with a simple permit from the division. But in a bizarre snafu, there were two signed versions of the agreement, one of which listed 11 aquifers not found on the other.
The division started issuing permits for injection wells drilled into those aquifers, even though they didn’t previously contain oil and weren’t viewed by the EPA as suitable for wastewater disposal. Under the agreement, the EPA has final say on which aquifers the oil industry can and can’t use.
The state even authorized oil companies to inject into a handful of aquifers already in use for drinking and irrigation, leading to the emergency closure of eight injection wells last year. Officials have now tested nine nearby drinking wells for contamination and found none. But aquifers tainted with chemicals are difficult and expensive to clean, and state water regulators say they can’t be certain that contamination won’t eventually turn up in those drinking water supplies.
Onus on oil firms
In the future, oil companies will need to build a case for why specific aquifers should be considered suitable for wastewater disposal, according to the division’s proposal. The companies will submit their data to the division and the State Water Resources Control Board for review. If those two state agencies agree, they will — together — ask the EPA to allow injections into those aquifers.
As for the 11 aquifers compromised by the 1983 bureaucratic mix-up, injections there will be phased out by mid-February 2017, unless the EPA decides to let them continue.
Revised Oil-Train Safety Rule Said to Delay Upgrade Deadline
by Jim Snyder, February 12, 2015
(Bloomberg) — The Obama administration revised its proposal to prevent oil trains from catching fire in derailments, giving companies more time to upgrade their fleets but sticking with a requirement that new tank cars have thicker walls and better brakes.
The changes, described by three people familiar with the proposal who asked not to be identified because the plan has not been made public, are in proposed regulations the U.S. Transportation Department sent to the White House last week for review prior to being released.
The administration is revising safety standards after a series of oil-train accidents, including a 2013 disaster in Canada that killed 47 people when a runaway train derailed and blew up. Earlier this month a train carrying ethanol derailed and caught fire outside of Dubuque, Iowa. No one was hurt.
Companies that own tank cars opposed the aggressive schedule for modifying cars in the DOT’s July draft, saying it would have cost billions of dollars and could slow oil production. That plan gave companies two years to retrofit cars hauling the most volatile crude oil, including from North Dakota’s booming Bakken field.
Railroads and oil companies fought the brake requirement and proposed a standard for the steel walls that was thinner than suggested by the agency.
‘Too Long’
Karen Darch, the mayor of the Chicago suburb of Barrington, Illinois, and an advocate for safer cars, said she was encouraged that the rules included stronger tank cars and upgraded brakes. She disagreed with adding years to the retrofit deadline.
“Taking more time on something that’s already taken too long is problematic,” Darch said Thursday in a phone interview.
Officials in the President Barack Obama’s Office of Management and Budget could change the proposal before the final version is released, probably in May. Darius Kirkwood, a spokesman at the Pipeline and Hazardous Materials Safety Administration, the Transportation Department unit that wrote the rule, said he couldn’t comment on a proposed rule.
“The department has and will continue to put a premium on getting this critical rule done as quickly as possible, but we’ve always committed ourselves to getting it done right,” Transportation Secretary Anthony Foxx said this month in a statement about the timing of the safety rule.
Rolling Deadlines
The current proposal would require companies to first upgrade tank cars known as DOT-111s, which safety investigators have said are prone to puncture in rail accidents, according to one of the people. Cars with an extra jacket of protection would remain in use longer before undergoing modifications, according to one of the people.
A newer model known as the CPC-1232, which the industry in 2011 voluntarily agreed to build in response to safety concerns, would have a later deadline than the DOT-111s for modification or replacement, three people said.
The CPC-1232s have more protection at the ends of the cars and than the DOT-111s and a reinforced top fitting.
The draft rule also would require that new tank cars be built with steel shells that are 9/16th of an inch thick, the people said. The walls of the current cars, both DOT-111s and CPC-1232s, are 7/16th of an inch thick.
A joint proposal from the American Petroleum Institute and the Association of American Railroads argued to set the tank-car shell thickness at half an inch, or 8/16ths.
Company Lobbying
Railroads and oil companies also lobbied against a proposal that the trains have electronically controlled pneumatic brakes, which are designed to stop all rolling cars at a same time.
The Association of American Railroads in June told Transportation Department officials that the electronic brakes would cost as much as $15,000 for each car and have only a minimal safety impact.
Trains often haul 100 or more tank cars filled with crude. These trains have increasingly been used to haul crude as oil production has boomed in places, like North Dakota, that don’t have enough pipelines.
Rail shipments of oil surged to 408,000 car loads last year from 11,000 in 2009.
