A step too far for the Appalachian Trail
by William V. DePaulo, Esq. via EC 29 Aug '19

29 Aug '19

https://www.politico.com/agenda/story/2019/08/29/appalachian-trail-dominion… The Trump administration wants Congress to change the law to allow a massive pipeline to cross the trail on federal lands. Congress should say no. By JONATHAN JARVIS *Jonathan Jarvis served as the 18th director of the National Park Service from 2009 to 2017.* 08/29/2019 05:05 AM EDT <https://www.politico.com/agenda/> Dominion Energy wants to run a massive pipeline across America’s treasured Appalachian National Scenic Trail and some of the least developed wildlands remaining in the East. This isn’t just a bad idea, it’s an unprecedented one. Dominion, the Virginia-based power giant that serves customers in 18 states, wants to do something that has *never* been done in the half century since the iconic hiking path was enshrined in law: force a pipeline across the Appalachian Trail on federal land managed by the Forest Service. To get its way, the company must persuade lawmakers to overturn a federal court decision and change a law that has protected important parts of the trail for almost 50 years. Congress should say no. The conservation of the American landscape is a deeply patriotic tradition to which I have dedicated my life. I grew up in the Shenandoah Valley of Virginia where my experiences along the Appalachian Trail and in the Blue Ridge Mountains fostered my love of the outdoors and my career in conservation. I climbed every mountain within sight of my home and fished every river. From 2009 to 2017, I served as director of the National Park Service, capping 40 years at the agency working to ensure—as Congress required when it passed the National Park Service Organic Act in 1916—that our national parks remain “unimpaired for the enjoyment of future generations.” The Appalachian Trail has been one of the jewels of our national park system since its creation in 1968. Every year, it draws millions of visitors, offering the opportunity to explore scenery and solitude from Georgia to Maine. Lands adjacent to the trail also provide important habitat for wildlife and plants. Like the creation of the trail itself, conservation has traditionally transcended politics. As a nation, we have decided to set aside some areas as national parks or designated wilderness and establish an American vision of conservation that resonates around the world. The writer and historian Wallace Stegner called our national parks “absolutely American” and “the best idea we ever had.” But that bipartisan idea is now under threat from an administration working aggressively to undo legal protections for our public lands. One of those threats is Dominion’s irresponsible route for the Atlantic Coast Pipeline, a pipeline that would carve its way across the Appalachian Trail, the Blue Ridge Parkway and two national forests. To be sure, many roads, powerlines and even pipelines already cross the trail along its 2,190-mile route, which winds its way across private, state and federal land. But as I and other trail hikers know, the national parks and forests where the trail runs are special. Their mountain vistas offer some of the most scenic and undeveloped wildland hiking in the East. Dominion’s pipeline would permanently affect the trail experience on these protected federal lands, carving up a largely forested mountain landscape with a cleared right-of-way the width of a multi-lane highway. To achieve its goal, Dominion has courted Trump appointees eager to promote the administration’s energy-at-any-cost agenda. Two years ago, it looked like Dominion might get its way. In January 2018, the Forest Service gave the company a permit to cross the Appalachian Trail on national forest land, but a coalition of conservation groups quickly challenged the decision in federal court. Eleven months later, the court concluded that, under federal law, the Forest Service did not have legal authority to allow the crossing and invalidated the permit. Dominion wants to overturn this court decision in Congress. The court relied on a federal law known as the Mineral Leasing Act, which since 1973 has prohibited oil and gas pipelines from crossing all units of the national park system, including Appalachian Trail segments on federal land. Almost five decades ago, Congress understood that pipelines presented extraordinary risks—including the effects of heavy construction, spills and explosions—that have no place alongside the natural beauty that our park system protects. Dominion wants lawmakers to upend that protection, changing the law to allow the Atlantic Coast Pipeline to cross the trail on national forest land. Congress should not roll back this longstanding protection for the Appalachian Trail on federal lands. Dominion has other options to cross the trail, and it must work with property owners, local communities and state and federal agencies to find an alternative route that will protect the trail’s integrity. America’s national park system is truly magnificent, a testament to our best instincts and aspirations as a nation, and it deserves the full protection that Congress has afforded it. William V.

One person was killed and more than 20 were injured in the sudden string of explosions caused by gas leaks in Lawrence, Andover and North Andover as blackish-gray clouds of smoke rolled across rooftops and flames shot into the sky. Leonel Rondon, 18, was killed while he sat in a car in the driveway of a home in Lawrence, the authorities said. A chimney fell onto the car, they said, when the home, on Chickering Road, exploded. Across the region, residents returned from work to find their homes burning and neighbors standing outside with no clear sense of what to do. Firefighters and other emergency workers raced from block to block, urging residents to evacuate to shelters that were hastily being opened. Along some blocks, the smell of gas hung in the air, and cellphones buzzed with evacuation warnings. ADVERTISEMENT “It looked like Armageddon, it really did,” Michael Mansfield, the fire chief of Andover, who has worked as a firefighter for almost four decades, told a CBS station in Boston. “There were billows of smoke coming from Lawrence behind me. I could see plumes of smoke in front of me from the town of Andover. It looked like an absolute war zone.” The string of explosions, fires and reports of gas odor — at least 70 of them, although officials were still trying to account for all of the damage late Thursday — came suddenly, beginning shortly before 5 p.m., without warning and without an immediate explanation from officials. But natural gas, and the possibility that gas had become overpressurized in a main, was the focus of many local authorities. Earlier in the day, a local gas company, Columbia Gas of Massachusetts, had announced <https://www.columbiagasma.com/en/about-us/newsroom/news/2018/09/13/improvin…> that it was “upgrading natural gas lines in neighborhoods across the state.” Late Thursday, the company issued a statement <https://www.columbiagasma.com/en/about-us/newsroom/news/2018/09/14/incident…>: “Columbia Gas crews are currently responding to reports of multiple fires in Lawrence. Our thoughts are with everyone affected by today’s incident.” Image Dan Rivera, the mayor of Lawrence, said it may take days to ensure that homes are safe to enter.CreditCJ Gunther/Epa-Efe, via Rex With three communities that are home to more than 100,000 people involved, the aftermath was chaotic, confusing and shifting by the minute. In some neighborhoods, firefighters found themselves putting out one fire, only to find another breaking out next door or down the block. Images from Lawrence showed several housing complexes bursting with flames and thick smoke billowing as firefighters rushed to the scenes. ADVERTISEMENT Annie Wilson, 73, was home alone in her third-floor apartment in south Lawrence when she smelled smoke. She opened her back door and smoke poured into the house. She ran out the front, and her parakeets flew away as she tried to rescue them. Fire quickly consumed the building. Ms. Wilson said she lost everything, including her husband’s ashes, which were in an urn, all her family photographs and all her clothes. “It was just crazy,” said Jessica Wilson, 43, Ms. Wilson’s daughter-in-law. “People were walking in the street with bags, kids were crying, there were sirens all over the place.” In the long hours after the fires, sections of the communities turned dark and silent, with power turned off and people told to leave. More than 18,000 customers were without electricity at one point on Thursday night. Long lines of traffic jammed the roads out of some towns. Traffic was crammed, too, near roads to shelters that were opened to those left homeless. Some exits off the major interstate highways were closed, and officials said the area’s schools would be shuttered on Friday. Thousands of people were left to sort out what to do. Some people said they were told to leave only if they smelled gas; others said they were told to leave regardless. Residents said they were uncertain whether to stay or go, and when they might return. “What we need folks to do is that if it’s happening in your home, you have a funny smell, just evacuate, come out to the street,” Mayor Dan Rivera of Lawrence told WBZ-TV <https://boston.cbslocal.com/2018/09/13/lawrence-fires-explosions-gas-main/> . The worst part, said Maria Santana, who was at home in Lawrence when she smelled gas, was that the explosions came without warning and that no one in authority seemed to have any idea of what was happening. A school not far from her home that her children and grandchildren had attended was damaged, she said. ADVERTISEMENT “We didn’t know anything then and we still don’t know anything,” she said. “We don’t even know how we’re standing up right now.” Image Natural gas, and the possibility that gas had become overpressurized in a main, was the focus of many local authorities on Thursday evening.CreditCarl Russo/The Eagle-Tribune, via Associated Press Maureen Taylor, 55, had been putting a roast in the oven at her Andover home when something seemed strange: The gas stove made the usual clicking noises, but it would not light. “I wasn’t getting any gas,” she said. “It was very bizarre.” A minute or so later, her phone buzzed with an alarm telling her to evacuate. “I’m very lucky that the stove didn’t go off,” she said. On her way to a senior center for shelter, Ms. Taylor saw two homes in her neighborhood burning. Officers were gathered on the streets. At the senior center, Ms. Taylor said she was surrounded by dozens of other people who wondered what would come next. “They’re worried about getting home,” she said. “They’re worried about their animals. Because really we were just given a few minutes to evacuate, and we keep hearing new information about whether we’re going to go back tonight or not.” As the night wore on, leaders of the three towns suggested that residents who had been evacuated needed to stay away — at least for now. No timeline for cleanup and safety checks was set, they said, and no one had a real sense of how much damage had been done. Mr. Rivera said the affected properties in Lawrence were south of the Merrimack River. He warned people not to return to their homes on Thursday evening, and that it may take days to ensure that homes are safe to enter. ADVERTISEMENT “If you are out of the house, stay away from your properties until we have made it safe for everyone,” Mr. Rivera said. “If you have not evacuated, you have just got to go. Trust us when we tell you that if you stay in your home, you will be at risk.” Gov. Charlie Baker said public safety officers and government officials are focused on trying to make sure that people are safe and that communities make it through the night safely, despite the loss of power and lingering fears over gas. Later, he said, he will turn his attention to what caused the explosion. “We’ll get to the question about what happened,” he said. Katharine Q. Seelye reported from Lawrence, Mass.; Farah Stockman from Cambridge, Mass.; Jacey Fortin from New York; and Monica Davey from Chicago. Andrew R.

WV Economic Growth (?) and Natural Gas
by William V. DePaulo, Esq. via EC 17 Aug '18

17 Aug '18

Ted Boettner, Dean Baker: Is WV's economic 'comeback' real? (Gazette Opinion) - By Ted Boettner and Dean Baker - 10 hrs ago - (0) <https://www.wvgazettemail.com/opinion/gazette_opinion/op_ed_commentaries/te…> *Local journalism makes a difference* Your support makes that possible — subscribe today <https://www.wvgazettemail.com/subscriptions> [image: Slide1.jpeg] Over the last few months there has been a flurry of op-eds and articles from big corporations and Republican lawmakers arguing that state budget cuts and low-wage policies like “Right-to-Work” are resulting in a booming economy in our state. Some have gone so far to say West Virginia is “America’s Comeback Kid.” West Virginia’s economy is growing in some sectors — most notably natural gas — but it is performing poorly compared to other states and has yet to recover from the Great Recession that begin more than 10 years ago. Let’s dig into the numbers. First, let’s look at our economic recovery from the Great Recession, which began in December 2007 and officially ended in June of 2009. Altogether, West Virginia has about 9,000 fewer jobs and has seen its labor force shrink by 34,000 from December 2007 to June 2018. Only one other state in the country (Wyoming, another energy state) has had slower job growth over this period. West Virginia also had a larger reduction in its workforce than any other state. The state’s economic growth – or change in real (inflation adjusted) Gross Domestic Product (GDP) – was about 9.1 percent from 2007 to 2017, less than 1 percent annually, compared to the U.S. average of 13 percent. Meanwhile, West Virginia is one of 13 states with an unemployment rate higher today than at the start of the Great Recession. As of June 2018, West Virginia had the third highest unemployment rate in the nation at 5.3 percent. Over the last year, employment has grown by 0.9 percent in the Mountain State, which was below the U.S. average and slower than most states. While West Virginia’s real GDP over the last two years has grown relatively fast compared to other states, this is almost entirely fueled by the rise in natural gas prices, which have grown by about 66 percent or $1 per thousand cubic feet over the last two years. The rise in natural gas prices has unleashed a pipeline building construction boom along with more natural gas production – growing from 1.3 trillion to 1.6 trillion cubic feet of production over the last two years. West Virginia’s real GDP grew by $1.8 billion over the last year. However, $1.4 billion or 78 percent of this growth was from the mining sector that includes natural gas extraction, coal mining, and other mining. The growth in natural gas extraction and metallurgical coal production is not only the central reason for the strong GDP growth over this period but it is mostly likely responsible for West Virginia’s relative strong earnings growth over the last year. This means that West Virginia’s politicians can’t really take credit for the growth of the last two years, unless they want to claim responsibility for the jump in world energy prices that gave us $3.00 a gallon gas. The loss of oil exports from Venezuela and Iran has far more to do with recent growth than the end of “Obama’s war on coal” While state and local public policy can impact economic growth – especially over the long-run (think infrastructure, education, higher education) – its effects are typically small in the short run outside of a burst of deficit spending (which has to be paid back over the medium-run) or a big infusion of federal money. For example, the expansion of Medicaid to working adults has increased federal spending in West Virginia by $900 million per year while the Trump tax cuts — that mostly go to the wealthy — will cut taxes by over $1 billion per year in West Virginia. Other factors that play a big role in state economic growth are climate, proximity to national markets, energy prices, the availability of raw materials and natural resources, and the composition of each state’s economy. The state is also largely at the mercy of national and global economic trends, such as economic recessions caused by housing and tech bubbles, or tight monetary policy through interest-rate hikes. Most people and businesses look for a good quality of life, sound infrastructure, world-class schools, and a place where they can make money. While jobs and our labor market are beginning to rebound, it is important that we have a clear understanding of the evidence and data before asserting that state or federal policies over the last several years are responsible for the recent economic growth. West Virginia’s economy still has a long way to go before it gets back to where it was over a decade ago and most of our economic growth is tied up in volatile industries where the benefits largely go out of state and the work is insecure. Over the last decade, most West Virginia households have seen no income gains from the state’s economic growth. If policymakers want to grow the state’s economy so it benefits everyone, not just a few, they will need to put more money, power, and skills in the hands of working families. This could include targeted tax cuts for low-income families, investing more in higher education and public broadband, raising the minimum wage, paid sick days for all, using severance taxes to build a sustainable future, and creating a paid family leave program. These policies not only keep more money inside our state, but they also provide a foundation for broader growth and prosperity.

Generation I wells used 3-5 millions gallons of water and 1-2 hundred pounds of sand per foot of lateral; gen II Wells, 5-10 million gallons, 500-1000 pounds of sand per foot; current gen III Wells, 10-30 million gallons, a ton of sand, and the laterals are now longer than 2 miles long. EIA forecasts a million more such wells in the next 20 years: you do the math. Might as well just transport The Fingerlakes and much of Wisconsin underground.

The Marcellus region (Pennsylvania and West Virginia) had the > lowest increase in water use (20%), from a median value of 23,400 m3 per > well in 2011 to 27,950 m3 per well in 2016, while the Permian Basin > (Texas and New Mexico) had the largest increase in water use (770%), from > 4900 m3 per well in 2011 up to 42,500 m3 per well in 2016. Median > water-use volumes varied largely among regions, with the Bakken region > using the least water (21,100 m3 per well in 2016) and the Permian basin > using the most water (42,500 m3 per well in 2016). One exception is the > Haynesville region, where water use per well decreased with time (*Fig. 2* > <http://advances.sciencemag.org/content/4/8/eaar5982#F2>). Horizontal > drilling requires producers to drill vertically to a target depth and then > curve the well horizontally through shale formations, maximizing the > surface area producing oil and gas.

We show below that > the hydrocarbon extraction intensity has similarly increased during this > period. Parallel to the increase in lateral lengths of the horizontal wells > and hydrocarbon extraction yields through time, the water use has also > increased. The relative increase in lateral length (0 to 80%) was, however, > significantly lower than the increase in water use (14 to 770%). There are > two exceptions to this observation: (i) in the Marcellus region, the > increase in lateral length (20%) was equal to the increasing water use > (25%); (ii) oil-producing wells in the Permian basin, where lateral length > increase (79%) and water-use increase (770%) were both higher than those in > the other studied regions. When water use per well is normalized to the > length of lateral section of the horizontal well, in almost every case, we > observed an increase in water use per length of the horizontal well.

https://www.popsci.com/fracking-fresh-water New fracking wells are using hundreds of times more water than their predecessors The change between 2011 and 2018 is stark. By Kat Eschner <https://www.popsci.com/authors/kat-eschner> 1 hour ago [image: water flowing over rocks] Fresh water is important to life, and industries. EcoPic <https://depositphotos.com/4563348/stock-photo-flowing-water.html> Over the last few years, fracking operations have gotten more efficient at removing oil and natural gas from the ground—this according to a new study <http://advances.sciencemag.org/content/4/8/eaar5982> published today in the journal Science Advances. That’s good news for the fossil fuels industry, which is getting more than ever out of a given well—but might be bad news for fresh water. The story isn’t the same everywhere. Ever since oil and gas prices decreased in 2014, the number of fracking wells being drilled annually across the country has gone down. But the size and output of the new wells that are being drilled has increased dramatically, because of a method known as horizontal drilling that maximizes the amount of surface area underground for the oil to flow through. Another thing has skyrocketed: the amount of water used in each well. In some places, says study author Avner Vengosh, “this net increase per well caused overall increase” in water usage for fracking in regions where it is practiced. The increase was as much as a whopping 770 percent in the Permian region of West Texas. There, for gas-producing wells, water use went from from about 350 gallons per foot of well in 2011 to 2335 gallons per foot of well in 2016. But in others, such as the Marcellus region of Pennsylvania and West Virginia, the amount of water used overall for fracking stayed about the same even though wells got bigger, because there were fewer of them. The early numbers come from a paper Vengosh and others at Duke published <https://pubs.acs.org/doi/abs/10.1021/acs.estlett.5b00211> in 2015. That study established a baseline, says Vengosh–but when graduate student Andrew Kondash, the new paper’s first author, started looking at the water figures for 2015-2016, the numbers were much, much higher. This led the team to doubt their original data, Vengosh says. But some more work revealed that it was true—water use per well had gone up substantially, even as the number of wells dropped. To figure this out, Kondash looked at water usage data for six major shale deposits across the country. They evaluated how many wells had been drilled, how much water was used in each, and how much wastewater was produced. The totals here represent fracking’s “water footprint”–the fresh water that needs to go in for fracking to take place, and the water mixed with chemicals, sand and—sometimes <https://pubs.acs.org/doi/abs/10.1021/es402165b?journalCode=esthag>—radioactive isotopes that seeps out with the natural gas or oil. “It has been shown that the overall water withdrawal for hydraulic fracturing is negligible compared to other industrial water uses on a national level,” the study reads. Total industrial use is estimated <https://pubs.usgs.gov/circ/1441/circ1441.pdf> at almost 15 million gallons of water per day, for uses ranging from auto manufacturing to mining. “On a local scale, however, water use for [fracking] can cause conflicts over water availability, especially in arid regions such as western United States, where water supplies are limited.” Freshwater availability might be the limiting factor of fuel extraction in the Permian Basin of West Texas, says Vengosh. The oilfields there are predicted <https://www.houstonchronicle.com/business/energy/article/Permian-will-outpa…> to produce historic amounts of crude oil in the next few years—but without the freshwater to do it via fracking, says Vengosh, that wouldn’t be possible. “The water use is part of the system that cannot be mitigated in any way,” he says. The demand for fresh water could promote innovation in fracking technologies. “In many places, the amount of water that’s recycled has gone up” in recent years, says McGill University’s civil engineer Mary Kang, who studies groundwater and fracking. Kang was not involved in the current project. It’s possible that innovation might make water recycling more efficient, says Vangosh. The increased water use means there’s the other factor, he says. “Now they need to deal with a much larger volume of wastewater.” A current common way to deal with it is to pump it into deep wastewater wells, rather than recycling it. That deals with the immediate problem for each individual well, but little is known about the long-term effects. Wastewater injection wells have been linked to increasing numbers of earthquakes <https://www.popsci.com/wastewater-injection-oklahoma-earthquake> in Oklahoma. “Water is not just some uniform resource,” says Kang. Water accessibility and quality are highly variable between locations—and there are parts of the water supply we still don’t really understand yet, like the deep groundwater that she studies. This new study gives everyone from industry to environmentalists a new baseline for figuring out how much water will be used in fracking, and is likely to prompt at least some to reevaluate their water budgets. But the grand total left in those water budgets, and the speed at which they’ll be consumed still remains to be seen. 860 Court Street, North Suite 300 Lewisburg, WV 24901 Tel 304-342-5588 Fax 866-850-1501 william.depaulo(a)gmail.com

MANCHIN, CAPITO AND McKINNEY ASK FERC TO REISSUE PERMITS FOR ACP AND MVP

https://www.wvgazettemail.com/news/politics/manchin-capito-mckinley-weigh-i… Manchin, Capito, McKinley weigh in on stopped pipelines - By Kate Mishkin Staff writer <https://www.wvgazettemail.com/users/profile/Kate%20Mishkin> - 2 hrs ago - (0) <https://www.wvgazettemail.com/news/politics/manchin-capito-mckinley-weigh-i…> Three members of West Virginia's congressional delegation have weighed in on two controversial natural gas pipelines, urging federal regulators to keep building them. In a letter dated Monday <https://www.documentcloud.org/documents/4757076-Manchin-Capito-McKinley-Pip…>, Sens. Joe Manchin, D-W.Va., Shelley Moore Capito, R-W.Va., and Rep. David McKinley, R-W.Va. urged the Federal Energy Regulatory Commission to allow construction to resume on the Atlantic Coast Pipeline and Mountain Valley Pipeline as quickly as possible. Construction on both natural gas pipelines was recently halted after the 4th Circuit Court of Appeals ruled that various federal agencies had skirted environmental protections when they approved the projects. FERC issued a stop work order on the Mountain Valley Pipeline late on Aug. 3, and then ordered a halt to the Atlantic Coast Pipeline exactly one week later, on Aug. 10. Environmental and citizen groups called the decision to stop work on both pipelines, at least until federal agencies can issue new permits and resolve the environmental problems, a victory. But in their letter, the lawmakers focused on the jobs and tax revenue that's now on hold. "We write to bring our concerns to your attention, as well as to encourage FERC and the relevant permitting agencies to quickly reconsider, correct and reissue the necessary permits for these projects," they wrote. None of the lawmakers responded to an interview request Tuesday, though. Reps. Alex Mooney and Evan Jenkins didn't sign the letter but their constituents have written to FERC about the pipelines. Mooney wasn't available for a comment, but a spokeswoman for Jenkins responded in an email. "I understand that many people have concerns about these pipelines, but I am confident that FERC and the pipeline developers will find an environmentally-friendly way to move these projects forward in a manner that is fair to landowners.” Jenkins said through a spokeswoman. Gov. Jim Justice, who, in June, said he'd "determine what role the state may play in expediting the construction" of the Mountain Valley Pipeline, also did not respond to a request for comment. Both pipelines will cross all three congressional districts -- the 300-mile-long Mountain Valley Pipeline from Wetzel County, West Virginia to Pittsylvania County, Virginia, and the 600-mile-long Atlantic Coast Pipeline from Harrison County, West Virginia to eastern North Carolina. In the letter, the lawmakers pointed to natural gas as a solution to the state's economic challenges. "We strongly encourage you to work with the permitting agencies in question to resolve the outstanding issues as quickly as possible in a manner that allows for re-issuance of these permits and recommencement of construction," the letter says. "We also ask that you consider amending or lifting the stop work orders on these projects to ensure that the shortest possible portions of the proposed routes are affected by these delays." FERC tapped the brakes on the Mountain Valley Pipeline <https://www.documentcloud.org/documents/4757123-FERC-MVP-Stop-Work-Order.ht…> after an appeals court vacated the Bureau of Land Management’s decision to grant a right of way and the U.S. Forest Service’s decision to allow a right of way and construction through the Jefferson National Forest. In the unanimous decision, Judge Stephanie Thacker wrote that American citizens put their faith in the Forest Service "to protect and preserve this country's forests, and they deserve more than silent acquiescence to a pipeline company's justification for upending large swaths of national forestlands." Then, the appeals court issued an order pulling a right-of-way permit for the National Park Service that authorized construction of the Atlantic Coast Pipeline <https://www.documentcloud.org/documents/4742097-FERC-ACP-stop-work-order.ht…> across the Blue Ridge Parkway and issued a longer explanation for its May 15 decision to pull the U.S. Fish and Wildlife's Incidental Take Statement for the pipeline. On Friday, FERC issued an order stopping that pipeline, too. Per FERC's order, Mountain Valley Pipeline has submitted a 16-page temporary stabilization plan that suggests, among other things, that pipe should be lowered into the ground to avoid UV exposure. The Atlantic Coast Pipeline hasn't yet submitted its stabilization plan. Reach Kate Mishkin at kate.mishkin(a)wvgazettemail.com, 304-348-4843 or follow @katemishkin on Twitter.
