The U.S. Environmental Protection Agency will propose regulations aimed at cutting methane emissions from the oil and gas sector by up to 45 percent over the next decade from 2012 levels…

The regulations on methane are one part of the Obama administration’s strategy to curb greenhouse gases and combat climate change and come just two weeks after the president unveiled a sweeping rule to slash carbon emissions from the country’s power plants.

The proposal that will be unveiled on Tuesday aims to reduce oil and gas industry methane emissions by up to 45 percent from 2012 levels by 2025, a goal it first announced in January, one source said.

The rules are intended to put the United States on course to meet its pledge to the United Nations climate change talks to cut its greenhouse gas emissions 26-28 percent below 2005 levels by 2025…

The U.S. boom in natural gas and oil production has raised concerns about leaks and venting of methane throughout the production process – from wells to transmission. So far, programs aimed at preventing those leaks have been voluntary.

Methane is the main component of natural gas, but when it is released into the atmosphere, it becomes a potent greenhouse gas…

Industry groups have said blah, blah, blah and requiring companies to buy that extra equipment is costly blah, blah, blah, blah

…Advocates for stricter methane rules have said capturing methane is mutually beneficial for oil and gas companies, and would save them money in the long run.

Detecting those leaks and capturing the methane with technology that is currently on the market can save companies money and help them produce oil and gas more efficiently, they say.

Honestly, the oil and gas industry is so accustomed to passing along the slightest cost to consumers you’d think they wouldn’t utter a peep over a regulation like this. Especially, since they’d be recapturing product they can sell along.

Expenses really aren’t anything special to this crew. I always recall taking a phone call from a driller in the Persian Gulf, BITD. He needed a couple hundred dollars worth of repair parts for a pile driver. Now.

He’d already ordered the parts over the phone from the warehouse of the firm I worked for and just wanted me to handle our portion of expedited delivery. I personally walked to the warehouse – put the two boxes of parts on a hand truck and wheeled them back to the front door of our office where a taxi was waiting.

I rode with them to the New Orleans International Airport where a chartered jet freighter was waiting with the door open. I set the two boxes of parts inside. The jet took off for DuBai.

Nothing else on board but those two boxes of parts.

Feds allow million$ of natural gas to be wasted by oil/gas-field managers

Significant amounts of natural gas on federal lands are being wasted, costing taxpayers tens of millions of dollars each year and adding to harmful greenhouse gas emissions, a GAO investigation has found.

The nonpartisan Government Accountability Office also said the Bureau of Land Management failed to conduct production inspections for hundreds of high-priority oil and gas wells — roughly 1 out of 5 — to ensure full payment of royalties to the U.S.

The report…is the latest to highlight substantial gaps in oversight. An AP review of government records last May found the agency, which manages oil and gas development on federal and Indian lands, had been overwhelmed by a boom in a new drilling technique known as hydraulic fracturing, or fracking.

The GAO report said it had been urging BLM, an agency of the Interior Department, to update guidelines for the burning or venting of natural gas since at least 2010, when it found 40 percent of it could be captured economically and sold. BLM has yet to do so, although agency officials now say they are in the process of putting together various orders and a proposed rule for comment later this year.

Until then, government investigators called BLM’s management of oil and gas “high-risk” for waste and fraud.

“The Interior Department has known for at least a decade that companies have been wasting natural gas from oil and gas wells on public lands,” said Sen. Ron Wyden, D-Ore. “Venting and flaring natural gas from these wells hurts the environment and speeds up global warming, and it shortchanges the taxpayers.”

He joined Reps. Peter DeFazio, D-Ore., and Raul Grijalva, D-Ariz., the top Democrat on the House Committee on Natural Resources, in calling on the department to redouble efforts to stem waste, rather than give “drilling companies a pass to let millions of taxpayer dollars evaporate into thin air.”…

Much of the vented gas is methane, a greenhouse gas roughly 25 times more potent than carbon dioxide. Using EPA estimates, the GAO concluded that capturing the vented gas would be the equivalent of removing 3.1 million cars from the road or closing four average-sized coal-fired power plants…

Yup. BLM has one guaranteed excuse. No way any ethical human being expects any regulation of fossil fuel production to come out of Congress. That includes regulations for safety, environment and, of course, fiscal responsibility. Ignoring responsibility for the fallout from any American process generating profit is one of the areas where Congress exceeds world records for incompetence.

But, Ron Wyden makes a serious point. The role of inept has been a Romulan cloak of invisibility draped around the shoulders of federal bureaucrats for way too long. From the Bush League on through Uncle Obama’s clean-hands-approach to governance – beancounters have taken precedence over accomplishment. The kind of people who think they qualify as Olympians for their ability to jog in place have been in charge too long.

Abandoned oil wells still spewing methane into the air we breathe


Just in the first oil boom state, Pennsylvania — 200K/1 million abandoned oil wells

Some of the millions of abandoned oil and natural gas wells in the United States are still spewing methane, marking a potentially large source of unrecorded greenhouse gas emissions, according to a study released on Monday.

Researchers at Princeton University measured emissions from dozens of abandoned wells in Pennsylvania in 2013 and 2014 and found they were emitting an average of 0.27 kg (0.6 lbs) of methane per day, according to the study published in the Proceedings of the National Academy of Sciences.

“These measurements show that methane emissions from abandoned oil and gas wells can be significant,” according to the study. “The research required to quantify these emissions nationally should be undertaken so they can be accurately described and included in greenhouse gas emissions inventories.”

The U.S. Environmental Protection Agency is mulling whether to issue mandatory standards for reducing methane emissions from the oil and gas sector as part of President Barack Obama’s broad climate action plan.

Presuming Barack Obama isn’t interned at Gitmo by the incoming Republican-dominated Congress.

Environmental groups have told the EPA that directly targeting methane rather than secondary volatile organic compounds, which the agency currently regulates, is more effective and can help the United States make steeper greenhouse gas emission cuts.

The history of extractive industries – whether mining or well-drilling – is one of the worst serial crimewaves in the United States. Between abandoned mines, wells ignored because their production of crap hydrocarbons isn’t sufficiently profitable – it is a tale of poisonous dangers left to rot.

If North Dakota oil wells had a mirror image aboveground…

More than 11,000 oil wells have been drilled in North Dakota since 2006, covering the state’s agricultural landscape. In all, almost 40,000 miles of well bores have been drilled underground to connect the fracking operations to surface wells. Laid end to end, they would circle the Earth about one and a half times.

On Sunday, The New York Times published a monthslong investigation by Deborah Sontag and Robert Gebeloff into North Dakota’s conflicted relationship with its booming oil industry. In the process of reporting that article, we obtained the locations of every oil drilling line of every well in the state.

The precise depths and directions of these remain out of sight for a very obvious reason: The drilling lines are underground. Here, we change that.

The illustrations shown here are accurate in every respect except one: We changed the vertical direction of each oil well bore to go above ground instead of below it. Otherwise, every bore line is shown precisely how it’s described by North Dakota’s Department of Mineral Resources.

Makes you feel all warm and fuzzy over lowered gasoline prices we’re all getting to enjoy. Why worry about air pollution when you can get in your car and drive to every sale in every brick-and-mortar store in your county over the weekend?

However – given my personal experience working for some of these profit-hungry creeps now awash in dollars as much as they are in oil – I could drive you into North Dakota blindfolded. And with the windows open in my pickup, you could tell when we were entering that oil field by the smell of what used to be clean air.

Did you ever realize how bad a comet smells?

Researchers describe the scent coming off 67P/Churyumov-Gerasimenko as reminiscent of rotten eggs and a horse stable.

They had outfitted Rosetta with a sort of artificial nose — an instrument called ROSINA — that can analyze gas vapors and replicate smell. Among other trace chemicals, Chury offers a powerful punch of hydrogen sulfide, ammonia, formaldehyde and hydrogen cyanide.

The strong presence of rotten egg (hydrogen sulfide) and horse stable (ammonia) smells are accented by notes of alcohol (methane) and vinegar (sulfur dioxide). In case that wasn’t gross enough, the hyrdogen cyanide and carbon disulfide offer a hint of sugared almonds.

Researchers say it’s the first time they’ve really gotten a good whiff of a comet.

“We’ve never been that close to a comet,” Kathrin Altwegg, the researcher who manages the ROSINA instrument from a lab at the University of Bern in Switzerland…

The comet — which Rosetta tried to anchor to with the exploratory craft called Philae — is 250 million miles from the sun. But it’s getting closer. And that’s bad news for astronomers with a weak stomach.

“The closer the comet gets to the sun, the more of its ice will evaporate, and the gas emissions will get more intense,” Altwegg explained to Deutsche Welle.

Sounds like the next time Earthlings sneak up on a comet and land on it to research its composition – we might include a little gas-powered engine in addition to solar panels to power the research vehicle. Something that runs on horse farts.

New Mexico is Ground Zero for methane contaminating our air

One small “hot spot” in the U.S. Southwest is responsible for producing the largest concentration of the greenhouse gas methane seen over the United States – more than triple the standard ground-based estimate — according to a new study of satellite data by scientists at NASA and the University of Michigan…

In each of the seven years studied from 2003-2009, the area released about 0.59 million metric tons of methane into the atmosphere. This is almost 3.5 times the estimate for the same area in the European Union’s widely used Emissions Database for Global Atmospheric Research.

…Researchers used observations made by the European Space Agency’s…SCIAMACHY instrument. SCIAMACHY measured greenhouse gases from 2002 to 2012. The atmospheric hot spot persisted throughout the study period. A ground station…operated by…Los Alamos National Laboratory, provided independent validation of the measurement…

Research scientist Christian Frankenberg of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, first noticed the Four Corners signal years ago in SCIAMACHY data…

The study’s lead author, Eric Kort of the University of Michigan, Ann Arbor, noted the study period predates the widespread use of hydraulic fracturing, known as fracking, near the hot spot. This indicates the methane emissions should not be attributed to fracking but instead to leaks in natural gas production and processing equipment in New Mexico’s San Juan Basin, which is the most active coalbed methane production area in the country.

“The results are indicative that emissions from established fossil fuel harvesting techniques are greater than inventoried,” Kort said. “There’s been so much attention on high-volume hydraulic fracturing, but we need to consider the industry as a whole…”

Phew! Where do we start?

The study includes time spent with Governor Bill the Democrat and Governor Susana the Republican. Both played kissy-kissy with our oil and gas industry. Sure, different levels of public blather; but, when push comes to shove, neither did a damned thing about oversight or regulation.

We shouldn’t be waiting for a Euro satellite or the coneheads up on the Hill to be telling us the air we breathe is being polluted. Everyone in the Four Corners knows it. Polluters, whether from the PNM power plants to gas and oil producers know it. They don’t care. And We The People – haven’t much of any elected officials really interested in acting on our behalf.

What could we have done? What can we do, now? How about a Green Party that actually tries to build political power instead of trotting out Ralph Nader every four years to tell us we’re screwed? Anyone concerned about quality of life already knows that. The rest of the population wallows in ignorance and ain’t reading Mother Jones. Most of our elected officials only respond to money and vested interests forking it over.

It’s time to stop the electoral posturing, put an end to political masturbation. That only perpetuates the absolute failure of any Green Party in the GOUSA. Our sister and brothers around the world enjoy our dissertations – and chuckle at how useless American environmentalists are at getting things done.

Aside from the Walt Disney theory of history which relies on electing a hero at the top – proven false most recently by the flop named Obama – reliance on the purportedly liberal wing of the two political parties we think is all we’re allowed is the broader example of being co-opted. Democrats respond to enviro fervor by saying, “Right on, y’all — vote for us and we’ll carry your banner to victory!” And then do nothing. Today’s Republicans do nothing by definition.

Nope. With continued polarization in this country – even if it’s based on the ignorance of perception – small victories, grassroots strength where possible, can provide the political power to make an independent difference. A Progressive swing vote in a gridlocked state legislature means a helluva lot more than buying TV time for this year’s self-chosen mellowed-out 60’s radical.

There are any number of city councils, state legislatures and eventually the bowels of Congress where program-based electoral campaigns can win the small victories which enable ecology gadflies to ally with other minorities to make a difference in how this state and this nation are run. And that includes the basic responsibility for oversight and regulation that restores our environment for future generations.

Microbes may have been responsible for the largest mass extinction of species in history


MIT professor of geophysics Daniel Rothman stands next to part of the Xiakou formation in China

A team of researchers from MIT may have found new evidence to shed light on the cause of the most devastating mass extinction in the history of our planet. The event, estimated to have taken place around 252 million years ago, was responsible for the extinction of roughly 90 percent of all life on Earth.

The team’s research indicates that the catastrophic event was in fact triggered by the tiniest of organisms, a methane-releasing microbe called Methanosarcina. New evidence suggests that at the time of the extinction, the microbes appeared in massive numbers across the world’s oceans, spreading vast clouds of the carbon-heavy gas methane into the atmosphere. This had the effect of altering the planet’s climate in a way that made it inhospitable to most other forms of life inhabiting Earth at that time.

It was previously believed that the mass extinction, known as the end-Permian extinction, was due to either vast amounts of volcanic activity, a devastating asteroid strike or prolific all-consuming coal fires. Any of these events could have caused the mass deaths, however there are inconsistencies in the evidence that point away from the traditional theories and towards the new findings presented by the researchers from MIT…

Although the team does not believe that…heightened levels of volcanism were responsible for the extinction itself, they do believe that it could have been the catalyst. The sudden and devastating increase in carbon-containing gases present during the end-Permian extinction is put down to a massive bloom of Methanosarcina. However, for this bloom to take place, the microbes would require an abundant source of carbon and nickel, both of which were discovered in a new analysis of sediments in China, and could have been distributed widely through a volcanic eruption.

The case for Methanosarcina being responsible for the extinction is further strengthened by the team’s findings that, at the time of the end-Permian extinction, the microbes had undergone a genetic transfer from another microbe. This is what gave the Methanosarcina the ability to produce methane at such a prolific rate.

With the catalyst of volcanic activity, the Methanosarcina were able to spread across our planet’s oceans unchecked. This allowed the microbes to produce vast quantities of carbon-containing methane, by harvesting the now carbon- and nickel-rich water. The release of said methane would have had the effect of raising the carbon dioxide levels in the waters, causing ocean acidification, irrevocably altering the ecosystem.

Let us hope no natural occurrence allows us to experiment firsthand with the hypothesis.

Of course, if such a cataclysm initiated, we can count on the usual assembly of know-nothings to stand around – doing their best to interfere with any attempt to save the species of Earth – while the rest of us die trying.

Signs of “new normal” in Earth’s climate apparent in hot 2012

Last year was one of the 10 hottest on record, with sea levels at record highs, Arctic ice at historic lows and extreme weather in various corners of the globe signaling a “new normal,” scientists said Tuesday in the 2012 State of the Climate report.

Meant to be a guide for policymakers, the report did not attribute the changes in climate to any one factor, but made note of continued increases in heat-trapping greenhouse gases including carbon dioxide, methane and nitrous oxide…

The report’s data indicate “new normal” conditions that can inform planning decisions, instead of relying on models that “count on the future being statistically a lot like the past,” Kathryn Sullivan said at a news briefing.

Global surface temperatures – land and water – were the eighth or ninth warmest, depending on which data set was used, since recordkeeping began in the late 1800s, the report found.

However, in the decade leading up to 2012, global temperatures actually declined by .05 degree C, according to Thomas Karl, director of NOAA’s National Climatic Data Center. Karl said the 50-year trend indicates global temperatures have consistently increased about .15 degree C per decade.

The recent decrease in temperatures has been noted by climate change skeptics who question the impact of human activities, such as the burning of fossil fuels that emit carbon dioxide, on climate.

However, other changes detailed in the report paint a more complex picture:

– Sea levels reached a record high, after a sharp decrease in 2011 possibly linked to the Pacific Ocean phenomenon La Nina, which can have a cooling effect;

– Arctic sea ice shrank to its smallest summer minimum since satellite records began 34 years ago, while Antarctic sea ice reached a record high;

– More than 97 percent of the ice sheet covering Greenland melted at least a bit in the summer of 2012, four times greater than the 1981-2010 average;

– Average sea surface temperatures rose, but not much, making 2012 among the 11th warmest years on record;

– Ocean heat was near record high levels in the upper half-mile of the water, and temperatures also increased in the deep ocean.

The State of the Climate report is being published as a supplement to the August Bulletin of the American Meteorological Society and is available online.

I suggest reading the whole report. Something in there for everyone, amateur or professional, scientist or advocate for science.

It will bore the crap out of “skeptics” who normally rely on ideologues who tell them what to believe.

Dairy powers itself with cow poop — including 42 tractor-trailers

Here at one of the largest dairy farms in the country, electricity generated using an endless supply of manure runs the equipment to milk around 30,000 cows three times a day.

For years, the farm has used livestock waste to create enough natural gas to power 10 barns, a cheese factory, a cafe, a gift shop and a maze of child-friendly exhibits about the world of dairy, including a 3D movie theater.

All that, and Fair Oaks Farms was still using only about half of the five million pounds of cow manure it vacuumed up from its barn floors on a daily basis. It burned off the excess methane, wasted energy sacrificed to the sky.

But not anymore.

The farm is now turning the extra manure into fuel for its delivery trucks, powering 42 tractor-trailers that make daily runs to raw milk processing plants in Indiana, Kentucky and Tennessee. Officials from the federal Department of Energy called the endeavor a “pacesetter” for the dairy industry, and said it was the largest natural gas fleet using agricultural waste to drive this nation’s roads.

As long as we keep milking cows, we never run out of gas,” said Gary Corbett, chief executive of Fair Oaks, which held a ribbon-cutting event for the project this month and opened two fueling stations to the public…

The American Gas Association estimates there are about 1,200 natural gas fueling stations operating across the country, the vast majority of which are supplied by the same pipelines that heat houses.

But the growing market is also drawing interest from livestock farmers, landfill management companies and other industries handling methane-rich material that, if harnessed, could create a nearly endless supply of cleaner, safer, sustainable “biogas,” while reducing greenhouse gas emissions.

To be sure, no one is pretending that waste-to-energy projects will become a major part of the larger natural gas vehicle market. But supporters say it could provide additional incentive to make biogas systems, which have lagged behind other sustainable energy solutions, more commercially viable.

RTFA. Partnerships are growing between dairy farmers and NatGas industry providers. They say we’ll be surprised how much they will grow over the next five years.

I’m ready to be surprised. In fact, I’m looking forward to it.

Did dinosaurs fart themselves into extinction?


 
Some scientific findings are just too good to leave alone, even if you don’t know if they can ever be confirmed: Such is the case for a study saying that plant-eating dinosaurs could have emitted enough digestive methane to warm Earth’s climate 150 million years ago.

“It is known that the time of these dinosaurs was warmer than now,” said David Wilkinson…lead author of a paper on the subject appearing in the journal Current Biology. “This is explained usually by an enhanced greenhouse effect, mainly carbon dioxide. If we are correct, then methane from sauropods may have been a contributor to this greenhouse effect.”

Methane is a more potent greenhouse gas than carbon dioxide, and modern-day livestock are thought to be responsible for about a quarter of the methane released in the United States. Some say that the belches and flatulence of cattle, pigs and sheep are a significant contributor to the warming effect caused by greenhouse-gas emissions. So why wouldn’t it have been the same in the age of giant plant-eating dinosaurs, when global biomass density was at least several times what it is today..?

He and his colleagues ran the numbers, using what they saw as conservative estimates for the total amount of dinosaur biomass and methane production rates per kilogram of body mass. They came up with a figure of 520 million tons of methane emitted per year, which is more than total modern-day methane emissions from all sources, natural and industrial. The current estimate for total methane emission is around 500 million tons a year, with 50 to 100 million tons of that coming from ruminant animals such as cows and goats, Wilkinson said…

Biologists have found that most of the modern-day methane emissions from livestock come from belching rather than flatulence. Was it the same for dinosaurs? “We have no particular view which end of the sauropod the methane came out,” Wilkinson told me. “Could be either or both…”

“What our simple calculations show is that, yes, it could. It’s a real possibility. But we don’t show that it did happen,” he said. “That would require much more work, and indeed it may be impossible to completely prove this without a time machine.”

Perhaps we might send some sort of device back through — eventually. It needn’t have a human pilot. Just a sensor-sniffer of sorts.
