WASHINGTON | Mon Dec 31, 2012 10:34am EST

WASHINGTON (Reuters) - Regardless of who takes the reins, the U.S. Environmental Protection Agency will likely face continued legal battles in President Barack Obama's second term as it tries to finalize pollution rules for power plants, analysts said.

EPA Administrator Lisa Jackson, who spearheaded the Obama administration's regulation of carbon emissions, said on Thursday she will step down after almost four years.

Her tenure was marked by opposition from industry groups and Republican lawmakers to the EPA's first-ever crackdown on carbon emissions, as well as other anti-pollution measures.

Analysts said whoever succeeds Jackson will probably face a spate of lawsuits to challenge rules that the EPA will finalize governing power plants, industrial sources and oil and gas production.

"This is shaping up to be four years of litigation," said Christopher Guith, vice president for policy at the U.S. Chamber of Commerce's Energy Institute.

Given the partisan divide, Guith said, legislators would struggle to draft laws that could serve as alternatives to the EPA's pending suite of carbon and air regulation.

"As we look to an even more divided Congress, the action will be in the federal courts," he said.

The U.S. Court of Appeals for the District of Columbia circuit, which hears most challenges to federal environmental rules, is likely to be busy as industry groups and states bring their cases against the EPA's rules after they are finalized.

The court sided with the agency in most of the recent challenges, most notably upholding its decision to use the Clean Air Act to regulate carbon dioxide emissions.

David Doniger, policy director of the Natural Resources Defense Council's Climate and Clean Air Program, said this could bolster the EPA as it tackles rules that may be more controversial than those rolled out under Jackson.

"The agency has a very good batting record on the clean air side. Carbon and climate (regulations) have come through completely unscathed," he said.

CARETAKER ADMINISTRATOR?

After the EPA was a political lightning rod during the first Obama administration, the president is likely to seek out a safe, possibly internal choice as Jackson's successor, or to avoid the confirmation process altogether.

"There are just so many arrows pointed at this agency," said Susan Tierney, managing principal and energy and environment specialist at Boston-based Analysis Group

Bob Perciasepe, deputy EPA administrator, will take over on an interim basis and could continue in that role indefinitely.

He previously worked at the EPA during the Clinton administration, specializing in water and air quality. Before rejoining the agency, Perciasepe was a top official at the National Audubon Society, a major conservation group.

Tierney said she expects the EPA to stay the course on its current agenda, especially as the agency faces some court-ordered deadlines to finalize rules, such as for coal ash, industrial waste from coal-fired plants and ozone standards.

PRIORITY ON CLIMATE CHANGE?

Some environmentalists have criticized Obama for being too timid on climate issues during his first term. But in his acceptance speech on election night in November the president gave a nod to climate change, raising hopes for more activism.

The White House may lean on the EPA to tackle one of the largest sources of U.S. greenhouse gas emissions, the current fleet of power plants, said Jeremy Symons, senior vice president at the National Wildlife Federation.

"The president has made clear that climate change is one of his top three priorities for the second term, so that means EPA needs to do its job," Symons said.

This, he said, means the agency needs to finalize the rules for new power plants and the standards for limiting carbon emissions from existing power plants.

The NRDC's Doniger said once the EPA meets an April 2013 legal deadline to finalize the greenhouse gas rules for new power plants, it will then have to address standards for existing plants.

The EPA has to start promptly in the beginning of the second term, said Doniger, because the rulemaking process is "a multistep process that will take time."

The controversial task will almost certainly trigger lawsuits because the rules will target a large number of domestic power plants and could jeopardize electric reliability.

"It's high stakes litigation when you are talking about bringing 40 percent of generation under regulations. That's disastrous," the Chamber's Guith said.

Guith said that while the EPA does have the authority to regulate carbon dioxide using the Clean Air Act, its rules are too difficult for industry - forcing the litigation.

"This EPA has been so aggressive in pushing the envelope by way of the compliance timeline that it has made itself more vulnerable to lawsuits," he said.

The EPA may also face legal challenges from environmental groups and certain states. The NRDC, the Environmental Defense Fund and the Sierra Club joined a group of nine states led by New York that threatened to sue the EPA last year to propose air pollution standards for oil and gas drilling.

They said that the drilling, transportation and distribution resulted in a significant release of methane, a potent greenhouse gas that is not regulated by federal rules.

Doniger said the group is trying to negotiate a timeline with the EPA to set a rule but could sue the agency if it doesn't agree a schedule by February.

Farmer Gail Wright is pictured next to a water pump which he says he is likely to shut down because the Ogallala Aquifer no longer provides adequate water near Sublette, Kansas, November 26, 2012. Residents of the Great Plains over the last year or so have experienced storms reminiscent of the 1930s Dust Bowl. Experts say the new storms have been brought on by a combination of historic drought, a dwindling Ogallala Aquifer underground water supply, climate change and government farm programs.

LIBERAL, Kansas | Sun Dec 30, 2012 9:16am EST

LIBERAL, Kansas (Reuters) - Real estate agent Mark Faulkner recalls a day in early November when he was putting up a sign near Ulysses, Kansas, in 60-miles-per-hour winds that blew up blinding dust clouds.

"There were places you could not see, it was blowing so hard," Faulkner said.

Residents of the Great Plains over the last year or so have experienced storms reminiscent of the 1930s Dust Bowl. Experts say the new storms have been brought on by a combination of historic drought, a dwindling Ogallala Aquifer underground water supply, climate change and government farm programs.

Nearly 62 percent of the United States was gripped by drought, as of December 25, and "exceptional" drought enveloped parts of Kansas, Colorado, Oklahoma, Texas, and New Mexico, according to the U.S. Drought Monitor.

There is no relief in sight for the Great Plains at least through the winter, according to Drought Monitor forecasts, which could portend more dust clouds.

A wave of dust storms during the 1930s crippled agriculture over a vast area of the Great Plains and led to an exodus of people, many to California, dramatized in John Steinbeck's novel "The Grapes of Wrath."

While few people believe it could get that bad again, the new storms have some experts worried that similar conditions - if not the catastrophic environmental disaster of the 1930s - are returning to parts of Texas, Oklahoma, New Mexico, Kansas and Colorado.

"I hope we don't talk ourselves into complacency with easy assumptions that a Dust Bowl could never happen again," said Craig Cox, agriculture director for the Environmental Working Group, a national conservation group that supports converting more tilled soil to grassland. "Instead, we should do what it takes to make sure it doesn't happen again."

Satellite images on December 19 showed a dust storm stretching over an area of 150 miles from extreme southwestern Oklahoma across the Panhandle of Texas around Lubbock to extreme eastern New Mexico, said Jody James, National Weather Service meteorologist in Lubbock. Visibility was reduced to half a mile in places, stoked by high winds, he said. At least one person was killed and more than a dozen injured in car crashes.

"I definitely think these dust storms will become more common until we get more measurable precipitation," James said.

'DIRTY 30S'

The Great Plains is a flat, semi-arid, area with few trees, where vast herds of buffalo once thrived on native grasses. Settlers plowed up most of the grassland in the late 19th and early 20th centuries to create the wheat-growing breadbasket of the United States, encouraged by high commodity prices and free "homestead" land from the government.

The era known as the "Dirty 30s" - chronicled by Ken Burns in a Public Broadcasting Service documentary that aired in November - was when a 1930s drought gripped the Great Plains and winds carried away exposed soil in massive dust clouds.

Bill Fitzgerald, 87, a farmer near Sublette, Kansas, remembers "Black Sunday" on April 14, 1935, when a clear, sunny day in southwest Kansas turned black as night by mid afternoon because of a massive cloud of dust that swept from Nebraska to the Texas panhandle.

"My older brother and I were in my dad's 1927 or '28 Chevy truck a mile north and a mile west of the house and we saw it rolling in," Fitzgerald said. "It was about 10 p.m. when it cleared enough for us to go home."

Farming practices have vastly improved since the 1930s. Farmers now leave plant remnants on the top of the soil and less soil is exposed, to preserve moisture and prevent erosion.

Irrigation beginning in the 1940s from the Ogallala aquifer, a huge network of water under the Great Plains, also made land less vulnerable to dust storms.

DRYING UP

But the Ogallala aquifer is drying up after years of drawing out more water than was replenished.

Many farmers have had to drill deeper wells to find water. Others are giving up on irrigation altogether, which means they can no longer grow crops of high-yielding and lucrative corn. They will instead grow wheat, cotton or grain sorghum on dry land, which depends completely on natural precipitation in an area that typically gets 20 inches of rain a year or less.

Near Sublette, Kansas, farmer Gail Wright said he would probably give up irrigating two square miles of his land and would plant wheat and grain sorghum instead of corn because of the diminishing aquifer. Drilling deeper wells would cost $120,000 each, Wright said.

"When we drilled those wells in the 1960s and 70s, we were doing 1,500 or 1,600 gallons per minute," said Wright. "Now, they are down to anywhere from 400 to 600 gallons per minute. We probably pumped out 200 feet of water."

Another farmer in Sublette, 79-year-old Lawrence Withers, whose family farms land his grandfather settled in 1887, is resigned to a future without irrigation.

"We have pumped 170 feet off the aquifer, that's gone. There's just a little tick of water at the bottom," he said.

The Ogallala supplies water to 176,000 square miles (456,000 square km) of land in parts of eight states from the Texas panhandle to southern South Dakota. That amounts to about 27 percent of all irrigated land in the nation, according to the U.S. Geological Survey.

The volume of water in the aquifer stood at about 2.9 billion acre feet in 2009, a decline of about 9 percent since 1950, according to the Geological Survey. About two-and-a-half times as much water was drawn out in the 14 years ended 2009 as during the prior 15-year period, data shows.

The water may run out in 25 years or less in parts of Texas, Oklahoma and southwest Kansas, although in other areas it has 50 to 200 years left, according to the Geological Survey.

Rationing has been imposed on irrigation in the region but it may be too little too late.

"It's a situation where across the Plains the demand far exceeds the annual recharge," said Mark Rude, executive director of the Southwest Kansas Groundwater Management District.

RECORD DROUGHT

The worst drought in decades has exacerbated the situation. The semi-arid area around Lubbock, which typically gets about 19 inches of rain a year, received less than 6 inches in 2011, the lowest ever recorded. This year was better but still far below normal at 12.5 inches, meteorologist James said.

Climate change is also having an impact on the region, said atmospheric scientist Katharine Hayhoe, co-director of the Climate Science Center at Texas Tech University in Lubbock.

"It is definitely hotter in the summer and drier in the summer because of climate change," she said.

The average annual temperature in Lubbock has increased by one full degree over the last decade, according to National Weather Service data, and the average amount of rainfall has fallen during summer months by about .50 inch over the decade.

Some say government policies are making things worse.

Federal government subsidized crop insurance pays farmers whether they produce a crop or not, encouraging farmers to plant even in a drought year.

Another subsidized U.S. government program that pays farmers to take sensitive marginal land out of crop production and put it into grassland is gradually shrinking.

In a possible case of history repeating itself, high commodity prices are encouraging farmers to break up the land and plant crops when the 10-year conservation contracts with the government expire, said environmentalist Cox. This is similar to what happened in the 1920s when vast areas of grassland were plowed up.

The government also has imposed restrictions on how much land can go into conservation reserves to save money at a time of massive U.S. budget deficits, he said.

The amount of land in conservation reserves has declined by more than 2.3 million acres over the last five years in five states of the Great Plains - Texas, Oklahoma, Kansas, Colorado and New Mexico, according to U.S. Agriculture Department data.

If most of that land is plowed up for crops it could lead to more dust storms in the future.

"I think you are probably going to see increased erosion if that happens," said Richard Zartman, Chairman of the Plant and Soil Science Department at Texas Tech, adding that it was unlikely to get as bad as the Dust Bowl days.

China expands pollution monitoring to biggest cities

BEIJING | Sun Dec 30, 2012 12:43am EST

BEIJING (Reuters) - China plans to release hourly air pollution monitoring data in 74 of its biggest cities starting on New Year's Day, state media said on Sunday, in a sign of increasing responsiveness to quality-of-life concerns among prosperous urban people.

Choking pollution and murky grey skies in Chinese cities is a top gripe among both Chinese and expatriates.

Microscopic pollutant particles in the air have killed about 8,600 people prematurely this year and cost $1 billion in economic losses in Beijing, Shanghai, Guangzhou and Xi'an, according to a study by Beijing University and Greenpeace that measured the pollutant levels of PM2.5, or particles smaller than 2.5 micrometers in diameter.

The new monitoring will include not only PM2.5, but also sulfur dioxide, nitrogen dioxide, ozone and carbon monoxide, the Xinhua news agency said, citing a Friday announcement by the Ministry of Environmental Protection.

Data will be collected from 496 monitoring stations, it said.

First Beijing, then other cities have become more public about their air quality data since the U.S. embassy in Beijing began publishing hourly data from a pollution monitor installed on embassy grounds in Beijing.

The embassy's monitor often diverged with official air quality readings, adding to public pressure for the city to come clean about the state of its air.

The United States has extended its monitoring program to its consulates in China.

Sunday was a clear and sunny winter day in Beijing, with the levels of ozone and PM2.5 declared "moderate" or "good", according to embassy data. The Beijing Municipal Environmental Monitoring Center (www.bjmemc.com.cn) rated PM10 concentrations as "excellent".

Many Chinese cities have removed belching smokestacks and coal-burning factories from their centers in the past few years, but a rise in the number of cars during the same period has created new air quality problems.

After Jackson, EPA faces big decisions on U.S. fracking boom

NEW YORK | Fri Dec 28, 2012 12:01am EST

NEW YORK (Reuters) - The past four years of U.S. environmental regulation was marked by a crackdown on emissions that angered coal miners and power companies. Over the next four, the new head of the Environmental Protection Agency will have to decide whether to take on an even larger industry: Big Oil.

Following Lisa Jackson's resignation on Wednesday, her successor will inherit the tricky task of regulating a drilling boom that has revolutionized the energy industry but raised fears over the possible contamination of water supplies.

The controversial technique at the center of the boom, hydraulic fracturing, involves injecting millions of gallons of water laced with chemicals deep into shale rocks to extract oil and gas. It has become a flashpoint issue, putting the EPA -- charged with safeguarding the nation's water -- in the middle of a fight between environmentalists and the energy industry.

Both sides now eagerly await a major EPA research project into fracking's effects on water supplies due in 2014, as well as final rules on issues including the disposal of wastewater and the use of 'diesel' chemicals in the process.

It is unclear who will take the role, but the incoming chief may have a "huge impact" on the oil and gas industry, says Robert McNally, a White House energy adviser during the George W. Bush administration who now heads the Rapidan Group, a consulting firm.

On the one hand, energy industry and big manufacturers are warning the EPA not to impede a drilling boom that offers the promise of decades' worth of cheap energy. Meanwhile, environmentalists are pressing President Barack Obama to ensure the drilling bonanza is not endangering water resources.

"This administration clearly needs contributors to economic growth for its economic legacy as much as it needs to add to its environmental legacy," said Bruce Bullock of the Maguire Energy Institute at Southern Methodist University in Dallas.

"This appointment could be key in seeing which of those two legacies is more important."

There are many contenders for the role, but no clear front-runner as yet. But Obama is unlikely to win Congressional approval for a heavy-handed regulator, and there is no suggestion of a stringent crackdown.

Even Jackson, who suffered withering criticism from big industry and Republicans for her efforts to curb pollution and limit greenhouse gas emissions, has cautiously condoned the practice as safe, while acknowledging the need for greater study and, in some cases, oversight.

"(Fracking technology) is perfectly capable of being clean," Jackson said in February. "It requires smart regulation, smart rules of the road."

Jackson's successor may now be charged with refining those rules, and both energy companies and fracking critics are anxious about the outcome.

Industry body Independent Petroleum Association of America said the EPA has "hindered development" of oil and gas for four years, and looks forward to a new chief who will promote energy drilling "hand in hand" with environmental regulation.

Executive director of the Sierra Club environmental group Michael Brune says the EPA has "unfinished business" in addressing things such as the release of methane emissions during fracking.

APPETITE TO REGULATE

Some analysts say Obama will not risk the economic stimulus of cheaper, domestic energy by pushing for tougher regulations. The oil sector is one of the few bright spots in the U.S. economy; natural gas prices are near their lowest in a decade, a boon for manufacturers, and U.S. oil output is the highest in 18 years.

"Even before (Jackson's resignation) there didn't seem to be much of an appetite in the White House to regulate shale drilling on a federal level in the next couple of years," says Nitzan Goldberger, U.S. energy policy analyst with Eurasia Group.

But big drillers such as ExxonMobil and Chesapeake who have plowed billions of dollars into shale fields are watching carefully for any sign of new rules or oversight that could drive up costs, or limit access.

While fracking technology has been around for decades, it has only gained widespread use across dozens of states in recent years. The EPA, like many groups, has struggled to keep up with the expansion, according to Government Accountability Office reports released earlier this year.

After years in which states were mostly responsible for regulating onshore drilling, the new EPA administrator will be pressed to take a more central role. A Gallup poll this year showed drinking water contamination is the leading environmental concern among Americans.

A year ago, in the first U.S. government report of its kind, the EPA drew a potential link between water contamination in rural Pavillion, Wyoming and fracking, based on samples of ground water from the area. That study has been contested, and subsequent research has been inconclusive.

A firmer word on the impact may not emerge until 2014, when the EPA is expected to release the first exhaustive in-depth government study on the long-term effects of fracking on drinking water, commissioned by Congress over two years.

DIESEL, WASTEWATER AND FLARING

The debate rages over a diverse range of issues.

While fracking was exempted from the Federal Clean Water Act in 2005, operations that used diesel fuel, which contains a number of toxic chemical compounds, were not exempted.

However, what exactly constitutes "diesel" has been a bone of contention among oil firms and environmental groups.

"The question is how to define "diesel" - broadly or narrowly," says consultant McNally.

"It's a big issue especially for Bakken producers," he said, referring to the region of North Dakota where crude oil output has more than tripled in two years.

The EPA published a draft definition in May, which met with criticism from the industry and some legislators, but it will fall to the new administrator to set a final definition.

Under Jackson, the EPA also said it would begin to regulate the millions of gallons a day of wastewater that is withdrawn from wells after the fracking process, probably in 2014. This is usually trucked offsite and sometimes re-injected elsewhere, although increasingly it is being reprocessed for further use.

And eventually, the EPA could face pressure to backtrack on previous initiatives. In April, the agency relented to pressure from the industry, giving drillers until January 2015 to end the practice of "flaring" excess natural gas from wells that were not connected to pipelines. It had initially proposed that firms cease almost immediately.

For Jackson's successor, a central question is whether the EPA takes a broader role in the industry, or, as Jackson hinted a year ago, allows state officials to call most the shots when it comes to drilling:

"It's not to say that there isn't a federal role, but you can't start to talk about a federal role without acknowledging the very strong state role."

New routes for ships off California may help endangered whales

LOS ANGELES | Fri Dec 28, 2012 5:26pm EST

LOS ANGELES (Reuters) - Several endangered whale species may get a new lease on life when some cargo shipping lanes off the California coast are shifted next year.

Routes due to be changed by June 2013 are used by ocean-going cargo vessels, tugboats and automobile carriers near San Francisco Bay, the Channel Islands in central California and the ports of Los Angeles and Long Beach, environmental officials said on Friday.

The shipping channels overlap with whale feeding and migration areas, and several blue whales and fin whales have been killed by ships, they said.

"The issue really struck home for us" with those deaths, said Michael Carver, the U.S. National Oceanic and Atmospheric Administration (NOAA) deputy superintendent of Cordell Bank National Marine Sanctuary in northern California.

The changes will not reduce the risk to zero, said Sean Hastings, a resource protection coordination with NOAA's Channel Islands National Marine Sanctuary.

Financial incentives to get vessels to slow down on their approach to the California coast are also being considered, Hastings said, adding that boats are now asked to voluntarily slow down but they are not doing it.

The Cordell sanctuary and other protected patches of ocean near San Francisco and the Channel Islands are habitats for blue, humpback and fin whales, which are protected by the U.S. Endangered Species Act.

In 2007, four blue whales were believed to have been killed by ships near the Channel Islands, according to NOAA, and five whales were killed off the coast of San Francisco and in nearby areas in 2010.

This year, a fin whale was struck by a ship and died off the coast of San Francisco and a vessel is believed to have killed another fin whale that washed ashore in Malibu, near Los Angeles, NOAA said.

In November, the International Maritime Organization, which governs shipping worldwide, said it had adopted changes to lanes off the coast of California to reduce whale strikes by ships. One of the proposals, for example, involves moving a shipping lane near the Channel Islands north by one mile to avoid a whale feeding area, Hastings said.

Carver said the U.S. Coast Guard would consult with the shipping industry and the public before the lane adjustments take effect.

West Antarctica warming fast, may quicken sea level rise: study

OSLO | Mon Dec 24, 2012 1:56pm EST

OSLO (Reuters) - West Antarctica is warming almost twice as fast as previously believed, adding to worries of a thaw that would add to sea level rise from San Francisco to Shanghai, a study showed on Sunday.

Annual average temperatures at the Byrd research station in West Antarctica had risen 2.4 degrees Celsius (4.3F) since the 1950s, one of the fastest gains on the planet and three times the global average in a changing climate, it said.

The unexpectedly big increase adds to fears the ice sheet is vulnerable to thawing. West Antarctica holds enough ice to raise world sea levels by at least 3.3 meters (11 feet) if it ever all melted, a process that would take centuries.

"The western part of the ice sheet is experiencing nearly twice as much warming as previously thought," Ohio State University said in a statement of the study led by its geography professor David Bromwich.

The warming "raises further concerns about the future contribution of Antarctica to sea level rise," it said. Higher summer temperatures raised risks of a surface melt of ice and snow even though most of Antarctica is in a year-round deep freeze.

Low-lying nations from Bangladesh to Tuvalu are especially vulnerable to sea level rise, as are coastal cities from London to Buenos Aires. Sea levels have risen by about 20 cms (8 inches) in the past century.

The United Nations panel of climate experts projects that sea levels will rise by between 18 and 59 cms (7-24 inches) this century, and by more if a thaw of Greenland and Antarctica accelerates, due to global warming caused by human activities.

GLACIERS

The rise in temperatures in the remote region was comparable to that on the Antarctic Peninsula to the north, which snakes up towards South America, according to the U.S.-based experts writing in the journal Nature Geoscience.

Parts of the northern hemisphere have also warmed at similarly fast rates.

Several ice shelves - thick ice floating on the ocean and linked to land - have collapsed around the Antarctic Peninsula in recent years. Once ice shelves break up, glaciers pent up behind them can slide faster into the sea, raising water levels.

"The stakes would be much higher if a similar event occurred to an ice shelf restraining one of the enormous West Antarctic ice sheet glaciers," said Andrew Monaghan, a co-author at the U.S. National Center for Atmospheric Research.

The Pine Island glacier off West Antarctica, for instance, brings as much water to the ocean as the Rhine river in Europe.

The scientists said there had been one instance of a widespread surface melt of West Antarctica, in 2005. "A continued rise in summer temperatures could lead to more frequent and extensive episodes of surface melting," they wrote.

West Antarctica now contributes about 0.3 mm a year to sea level rise, less than Greenland's 0.7 mm, Ohio State University said. The bigger East Antarctic ice sheet is less vulnerable to a thaw.

Helped by computer simulations, the scientists reconstructed a record of temperatures stretching back to 1958 at Byrd, where about a third of the measurements were missing, sometimes because of power failures in the long Antarctic winters.
