How Underground Sensors in Texas Will Help NASA Predict Drought and Floods

Soil moisture meters across the state could one day help predict weather patterns across the state.

From StateImpact Texas:

Stanley Rabke’s family has lived and worked on their Hill Country ranch since 1889. Generations of Rabkes have struggled with the extremes of Texas weather, but one storm sticks out in Stanley’s memory: it came after the drought of the 1950s.

“It rained and rained and rained,” he says. “Back then we raised turkeys, we lost thousands of turkeys that washed away in the creek.”

The disaster underscores an irony of life in Texas. “You hope and pray that you’re going to get a good rain, [but] on the other side of it, you hope you don’t get a flood,” says Rabke.

A quick walk from where the turkeys met their fate, some new technology that will help manage that risk is being installed — soil monitoring sensors in the ground.

Keystone XL or Not, Canadian Crude Already Shipping Out From U.S.

While efforts to build out the Keystone XL pipeline have stalled in Congress, Canadian crude oil is still being shipped internationally from the Texas Gulf Coast.

Congress’ attempts to force approval of the Keystone XL pipeline have re-ignited debate over the project, which would allow more crude oil to flow from the tar sands of Canada to refineries on the Gulf Coast.  It’s also re-ignited debate over what could happen to that oil once it gets to Texas.

President Obama and opponents of the pipeline say it will be used as a funnel to export Canadian crude to international markets. TransCanada, the company building the pipeline, has been unequivocal when asked about that.

Climate Deal Puts Spotlight on Carbon Capture Technology

The deal that the U.S. and China have struck to curb carbon emissions has been hailed as a breakthrough by many concerned with climate change, and panned by politicians opposed to President Obama. But it's also captured the interest of a group of researchers -- some in Texas -- who specialize in carbon capture and sequestration technology.

The deal is short on specifics. But it commits the U.S. and China to continue investing in carbon capture, use and storage. That’s technology that filters CO2 from coal power plants and then pumps the carbon underground. Texas has been doing it for decades to get oil out of the ground in a process called enhanced oil recovery.

“It’s always poor form for Texas to do too much boasting, but the source of expertise for injecting CO2 for enhanced oil recovery lies mostly in Texas," says Susan Hovorka, a senior researcher scientist at UT’s Bureau of Economic Geology, who works on carbon sequestration.

  This week Denton, Texas became the first city in the state to ban fracking within its city limits. The ban passed with nearly 59 percent of the vote.

Many in Denton worry about how fracking and associated activities impact their health and quality of life.  But opponents say the ban is bad for the economy. The drilling industry, which pumped hundreds of thousands of dollars into the campaign against the ban, is concerned with the precedent Denton could set for other Texas towns.

Just hours after the vote, the Texas Oil and Gas Association (TxOGA) filed a legal challenge to the ban, as did the Texas General Land office with a suit.

There may be more legal challenges on the way.

The TxOGA lawsuit asserts that "the public policy of Texas is to encourage the full and effective exploitation of our mineral resources," says Tom Phillips, a lawyer with Baker Botts who is working on the challenge.

Decker Decommissioning Faces Complex Hurdles

From The Austin Monitor:

A key Austin Energy reserve fund that would be used to pay for the potential decommissioning of the Decker Lake gas generation plant has no money that could be used in that effort, according to Austin Energy.

Utility spokesman Carlos Cordova told the Austin Monitor in an email that a City Council-approved Austin Energy fiscal policy for funding such a decommissioning of a non-nuclear plant “should occur four years before the start of plant closure.”

Cordova continued: “The amount to set aside should be based upon a decommissioning study of the plant site. There are currently no funds in that decommissioning reserve and a decommissioning study has not been done. Council resolution 20140828-157, which includes replacing Decker with 600 megawatts of contracted utility-scale solar, will require funding of this reserve in the near future.”

Austin Energy officials would not hazard a guess at the full cost of decommissioning the plant. However, should the utility elect to replace the facility, it has estimated the cost of the construction of new transmission lines to be in the neighborhood of $150 million.

Voters Cast Ballots in First Ever Push to Ban Fracking in Texas

From StateImpact Texas:

For Cathy McMullen, the reasons to ban fracking in Denton are as obvious at the drilling rig that sits on the corner of Masch Branch and Hampton Road on the northwest side of town. It’s big, it’s noisy, and she believes it vents toxic emissions into the community. The site is, however, not very close to any houses.

“I’ll show you where this exact same thing was sitting by someone’s home,” she says.

Austin Energy Offers Solar Expansion as City Zeroes in on Carbon-Free Goal

Austin Energy offered a plan to bring 500 megawatts of solar power to the utility and retire the coal-powered Fayette Power Plant in an effort to reach the city's goal of becoming carbon-neutral.
Austin Monitor

Austin Energy officials presented City Council members Tuesday with a new proposal for a generation mix that would approach the renewable energy numbers suggested by a July task force report.

Though no solid generation plan has been presented — let alone approved — the utility’s latest suggestion would bring in 500 new megawatts of solar power, retire the coal-powered Fayette Power Plant by 2025 and retire the Decker gas generating facility by 2019, though a new gas facility could well replace it.

It Will Take an Insane Amount of Rain Before the Highland Lakes Recover

From StateImpact Texas:

Central Texas is having a pretty decent year, rain-wise. We’re sitting just below normal. And it’s been a good week, too: early Thursday, one part of Austin got over seven inches of rain.

So much rain fell over downtown Austin that the statue of Stevie Ray Vaughan along Lady Bird Lake looked like he was walking on water. It brought back memories of the Halloween floods last fall — back then Stevie was standing in water waist-deep. But these big rain events all have something in common: They really haven’t fallen where we need them most.

Aside from the month of August, this summer has been relatively cool as far as Texas summers go.

With that reprieve from stifling heat came an unanticipated gap in revenue for utility providers, and it's forced Austin Energy – which earns nearly half of its revenue in the hottest months of the year – to reexamine its budget.

Research Links Drilling Activities to Water Contamination in North Texas

For years, some residents of Parker County in North Texas have believed that nearby gas drilling was responsible for high levels of methane in neighborhood water wells. Research published today in the Proceedings of the National Academy of Sciences appears to back that up.

The study looked at water contamination in Texas and Pennsylvania. It suggests that faulty cement jobs on drilling wells could be at fault in North Texas. Cement is poured between the rock wall and the steel tubing of oil and gas wells to block contaminants.

“We think either there isn’t enough cement in this location or more likely there are cracks or imperfections in that cement. That’s what allowed the strong gas to move up through the well and then out into peoples drinking water,” says Robert Jackson, a professor of environmental sciences at Stanford, who co-authored of the study.

El Nino Flies Under the Radar in Summer, But Could It Still Bring a Wetter Texas Winter?

El Nino hasn't brought the wet summer promised by some meteorologists, but it could bring Texas rains this fall and winter.
Huma Munir/KUT News

Earlier this year Lower Colorado River Authority meteorologist Bob Rose, liked what he was seeing in the forecast.  

“I’m optimistic that we will get into a pattern of above normal rainfall this fall continuing into next winter and possibly into next spring as well,” he said in April.

Bur since this April things changed.

After much ado, the El Nino predicted by many meteorologists hasn’t quite showed itself in the form rainfall yet. While there’s still a chance it could strengthen before the summer’s end, it’s not likely it will meet its initial forecasted fury.

Why Closing a Power Plant Could Be Part of Austin's Water Solution

The city is moving to shut down Decker Power Plant to lower citywide emissions.
Mose Buchele/KUT

From StateImpact Texas:

The funny thing about Walter E. Long Lake is that most people don't know it exists.

The lake, tucked into a rural-feeling part of Northeast Austin is big, by Austin standards. It can hold more water than Austin's two central city lakes -- Lake Austin and Lady Bird Lake -- combined. It was created to host a power plant, which it's done for for nearly 50 years. That's how it got its other name: Decker Lake.

But last week, Austin's city council approved a plan to wean Austin off Decker Power Plant electricity, opting to shutter the plant to lower citywide carbon emissions. If that happens, the lake could serve as Austin’s new city reservoir.

From StateImpact Texas: 

After a surge in earthquakes across Texas over the last several years, state regulators are considering their options. On Monday, the House Subcommittee on Seismic Activity heard some of those options.

Many of the quakes are likely caused by wastewater disposal wells, where the liquid waste from oil and gas drilling is pumped back into the ground. The Railroad Commission of Texas is the agency that regulates the state’s oil and gas industry, and it is proposing new rules for those wells.

LCRA Delays Vote on Water Plan

Extreme drought and releases to farmers have lowered levels in Lakes Buchanan and Travis (pictured) in Central Texas. Now a state agency is saying more study is needed into how the reservoirs are managed.

Water from the Highland Lakes is important to everyone in Central Texas — from urban Austinites to rural rice farmers downstream. Wednesday, the board of the Lower Colorado River Authority was set to vote on a much-delayed plan to manage that water, but the authority's board postponed that vote to gather more public input. 

The proposed plan, which would ensure that more water stays in the lakes in times of drought, is widely supported by upstream stakeholders, namely the City of Austin.  But it’s unpopular downstream with agricultural interests that would likely see themselves cut off from water more often. The plan must ultimately be approved by the Texas Commission on Environmental Quality

This is an Ozone Action Day

First declaration for the 2014 ozone season
Jeff Heimsath for KUT News

For the first time since September, state officials have declared today an Ozone Action Day in the Austin-area. The declaration means weather conditions are expected to be conducive to lower-than-normal air quality.

The Air Quality Index is forecast to bad enough to affect sensitive groups, such as those with asthma or heart disease, elderly people and children. The general public should be okay. 

The U.S. Environmental Protection Agency sets a minimum standard for ozone of 75 parts per billion. 

“Our standard last year, we ended the 2013 ozone season at 73 parts per billion, so we’re actually okay, for now, but EPA expects to announce a new ozone standard in December of this year,”  Clean Air Force of Central Texas director Sarah Holland says.

During Drought, a Once-Mighty Texas Rice Belt Fades Away

In the floodplain, several inches of fine silty mud sit atop thick, heavy clay. The clay is the finest dust eroded by the river, carried until this point then deposited as the river spreads out across the prairie. The silt is a thick rich mixture of sediment.

From StateImpact Texas: 

In 2012, some farming districts on the Lower Colorado River were cut off from water for irrigation for the first time. Reservoirs were too low to flood tens of thousands of rice fields. Some asked, “Why would anyone be farming rice in Texas in the first place?”

The answer is long, and it begins with the fact that parts of Texas haven’t always been dry. For farmers like Ronald Gertson, who remembers driving a tractor through rice fields as a child, recent years have been hard to bear.

“It’s just unbelievable that it’s been so bad that we have had three unprecedented years in a row, and I recognize some experts say we could have a couple of decades like this. I hope and pray that’s not the case,” says Gertson, a rice farmer, chair of numerous water-related committees and, in recent years, unofficial spokesman for the Texas Rice Belt. “If that is the case then yeah, this whole prairie is going to change.”

But it has already changed.

The U.S. is in the middle of an oil drilling boom that few people saw coming. After decades of decline, crude oil production is rising again. Technologies such as hydraulic fracturing in places such as North Dakota are getting a lot of attention. But the Gulf of Mexico still accounts for more than one-fifth of domestic oil production.
