Sabic Innovative Plastics adds “cogeneration” facility freeing up considerable Vectren capacity

April 26, 2017 – by John Blair, valleywatch.net editor

Sabic Innovative Plastics, (Formerly GE Plastics) in Mt. Vernon, IN has decided to partially wean itself from the Vectren grid by building their own electrical and steam generation plant onsite. Their action frees up considerable capacity for Vectren, which still provides back up electricity for the giant plastics manufacturing facility east of Mt. Vernon.

For years and prior to the construction of the cogeneration plant, Sabic burned coal to generate steam used in the manufacture of a broad range of plastics including Lexan and Ultem. Sabic claims the cogeneration plant will create substantial environmental improvements in the region including a 35% reduction in Carbon Dioxide emissions and a 43% reduction in their “non-hazardous” waste primarily consisting of coal ash which previously had to be landfilled offsite. Sabic officially stopped using coal in January of this year.The cogeneration unit is fueled with natural gas from a new thirty mile pipeline which transverses the Ohio River running from Robards, KY.

One interesting fact we learned today was that the plant has about 25% higher generating capacity in the winter than in the summer due solely to ambient air temperature. In the winter, the plant is capable of producing more than 100 Megawatts while summer capacity is rated at 80 megawatts.

The plant originally began operations in 1960 by General Electric Company to produce a single product, Lexan but was purchased by Sabic in 2011.

In November, Vectren announced the pending retirement of their Warrick County facility Culley 2 as well their Posey County AB Brown plant, a move partially facilitated by the construction go the cogeneration plant.

It’s Time to Give Air Quality the Attention It Deserves

March 22, 2017 – by Bob Henson in the Wunderblog of Weather Underground.com

Each day of every year, a quiet disaster unfolds in households and hospitals across the world. More than 10,000 lives are lost worldwide every 24 hours as a direct or indirect consequence of poor air quality. Bad air takes its toll quietly, with no need for the oversized drama of a hurricane or tornado. Sometimes air quality becomes so dangerous that it can’t be ignored. Much of the time, though, dangerous air goes about its dirty work with little attention from policymakers and the public.

The World Health Organization (WHO) has dubbed air pollution “the world’s largest single environmental health risk.” It is high time we treated the life-threatening aspects of dirty air, and the life-sustaining properties of a clean atmosphere, with the full appreciation they ought to have.

Here at Weather Underground, we are taking steps in this direction by bringing air quality sensors into our 250,000-strong network of personal weather stations. We believe there is great power in being able to measure the quality of the air in one’s own neighborhood and to share that information with the world at large.  

We are also ramping up our coverage of air pollution issues here at Category 6. Along with occasional guest authors, Jeff Masters and I will be exploring the many facets of air quality, including its effects on people and ecosystems and how it intersects with both weather and climate. For example, Jeff will soon be posting an overview of the health hazards posed by poor air quality. This topic was highlighted on March 6 by a distressing report from the World Health Organization: Each year, respiratory infections linked to indoor and outdoor air pollution and second-hand smoke take the lives of some 570,000 children under the age of 5. That’s roughly 10% of all deaths in that age group each year.

For both children and adults, the air indoors can be just as dangerous as the air outdoors. Each year more than 4 million people die prematurely as a consequence of household air pollution—largely the result of inefficient, smoke-belching cookstoves that are used routinely in developing nations. This toll is even higher than the WHO’s estimate of 3 million premature deaths a year from outdoor air pollution.

Even the most pristine places can be touched by the global spread of air pollution. In Antarctica, scientists have found traces of lead trapped within ice cores. Using isotopes (variations in the number of neutrons within an element), researchers were able to track the heavy-metal pollution to industrial activity in Australia as far back as the late 1800s.

Today, as much as 25% of the sulfate and mercury pollution along the U.S. West Coast comes from emissions from coal-fired power plants in China. These pollutants take just five to eight days to cross the Pacific on the prevailing upper-level westerly winds.

Clean Coal is elusive and very expensive

March 1, 2017 – by David Schlissel, IEEFA. Editor’s note: Valley Watch and our colleagues, Citizens Action Coalition and Sierra Club have challenged the Edwardsport plant since 2006 before the IURC and IDEM. Sadly, we failed to stop the plant. David Schlissel has served as our “expert before the IURC on several of the “dockets.”

Construction Delays and Budget Overruns; Productivity Problems; High Operating Costs

If the “clean coal” integrated gasification combined cycle (IGCC) technology promoted at home and abroad by the U.S. utility industry sounds too good to be true, it’s because it is.

That’s why Moody’s Investors Services warned the other day that it might downgrade the creditof Mississippi Power Company because of the declining competitiveness of the company’s  Kemper County IGCC plant.

IGCC is experimental and expensive and may well always remain so. It aims to merge three separate procedures into one unified but exceptionally complicated operation.

Step one turns coal into what’s known as synthetic gas, or “syngas,” which is said to be more environmentally friendly to burn than coal itself. Step two removes carbon dioxide from the syngas (rather than taking it out “post-combustion,” as is traditional in coal-fired generation). Step three fires the gas and generates electricity.

Two IGCC plants have been built in the U.S. in recent years: Edwardsport Generating Station in Indiana and Kemper County Energy Facility in Mississippi. Each is a distinctive first-of-their-kind plant placed into production on a commercial scale at huge costs to ratepayers—by Duke Energy, which owns Edwardsport, and by Mississippi Power, the Southern Company subsidiary that runs Kemper.

PROMOTED AS THE FUTURE OF CLEAN POWER GENERATION IN AMERICA, NEITHER HAS LIVED UP TO ITS HYPE. 

Duke’s Edwardsport plant is an imposing place at night. unfortunately, it has never worked as Duke promised and has become, instead a real lemon for the company’s ratepayers who are stuck with the bill because the Indiana Utility Regulatory Commission gave Duke a blank check to spend as much as they wished knowing that ratepayers would pay in the end.. Photo © BlairPhotoEVV

Both Edwardsport and Kemper have proven far more expensive to build than originally proposed.

Edwardsport, which began construction in 2008 with an estimated budget of $1.985 billion, cost $3.55 billion in official construction costs by the time Duke began to put it online in 2013. That cost overrun, big as it is, actually understates the full price of the plant because it doesn’t include the more than $600 million Duke was allowed by regulators in Indiana to charge customers ahead of activation.

Kentucky Regulators, Industry Reps Privately Rewrote Coal Ash Rules

January 17, 2017 – by Erica Peterson, WFPL Radio

Kentucky’s Energy and Environment Cabinet has finalized a controversial plan to let the state’s utilities virtually self-regulate the storing of hazardous coal ash near power plants.

As details about the plan emerged over the past few weeks, Cabinet Secretary Charles Snavely defended the rules and the process, saying it included “full public participation.”

But documents obtained by WFPL News show the process was far from public and instead included more than a year of backroom meetings — under both former Gov. Steve Beshear and Gov. Matt Bevin — with representatives of the utility industry. During that time, documents show the regulations were significantly revised and weakened.

J. Tyler Franklin | wfpl.org

When regulators began meeting with representatives of the utility industry in September 2015, the regulations they had drafted (left) were extensive. By the time they submitted the drafts to the Legislative Research Commission in October 2016 (right), the regulations were weakened.

Environmental attorney Tom FitzGerald of the Kentucky Resources Council, who has spent more than 44 years working in the state, and oftentimes on workgroups with members of industry and regulators to craft regulations, said to his knowledge, such one-sided input from industry is unprecedented in recent years.

“I think it’s unconscionable, and I think it does not reflect well on how little value [the regulators] place on public involvement in the development of regulations that are intended to protect the public,” FitzGerald said.

Representatives from the Energy and Environment Cabinet declined an interview request. In response to emailed questions, spokesman John Mura defended the cabinet’s regulatory process.

“As a part of the pre-KRS 13A deliberative process of regulation development, it is common for the state to informally discuss regulatory matters with the regulated sector that are directly impacted by those regulations,” Mura wrote.

There is an easy way for Trump to show he is serious about unity

January 20, 2017 – by John Blair, valleywatch.net editor

I have a suggestion for President Trump. If he is serious about wanting to bring the country “together,” then there is one simple thing he can do to accomplish that. 

He could nominate Judge Merrick Garland today without hesitation and with that easy gesture, he would show deference to all of America as he outlined in his short speech today. 

After all, Garland already has support of the Senate Judiciary Committee Chairman, Orrin Hatch, who called Garland a perfect person for President Obama to nominate back about this time last year only to renege when Senate Majority figure head, Mitch McConnell decided that no one Obama might nominate is crazy enough. 

A Trump nomination of Garland would show that he is intent on following his own Inaugural Address depicting unity of all Americans. If Trump nominates one of the crazies on the list of potentials he released last summer, we could all be in for the ride of our lives. and that is no way to unify America.

Kentucky Environmental Agency claims that “media” is misleading the public on Coal Ash issue

After being the target of critical editorials in Kentucky’s two largest newspapers, Kentucky’s Energy and Environment Cabinet fired back Thursday with an internet posting that argues its proposed rules for coal combustion waste actually strengthen – not weaken – protection of the environment and public health.

The Naturally Connected blog from the Kentucky Department for Environmental Protection also takes aim at the media, arguing news coverage and editorials “mislead readers about the rules’ intent and potential effect on the health and welfare of Kentuckians.” By incorporating new regulations on the management of coal-burning wastes from the U.S. Environmental Protection Agency, Kentucky DEP argues, “the proposed state regulations would maintain and in some cases increase environmental and public protections, not diminish them.”

But one of the state’s top environmental attorneys quickly countered that it is state officials who are misleading the public with Orwellian arguments along the lines of “war is peace” and “ignorance is strength.”

Attorney Tom FitzGerald, director of the Kentucky Resources Council and an expert on Kentucky waste laws, called the state’s argument “pure sophistry,”  which means the use of fallacious arguments, especially with the intention of deceiving.

The new EPA based rule came after decades of fighting nationally over how ash and scrubber sludge should be handled. Coal ash contains contaminants like mercury, cadmium and arsenic, according to the EPA, and without proper management, these contaminants can pollute waterways, groundwater, drinking water, and the air.

►CJ EDITORIAL: Kentucky shouldn’t ease coal ash rules
►H-L EDITORIAL: Don’t weaken coal ash rules

Kentucky, among the nation’s biggest coal-burning waste generators, argues that the proposed regulations will require managing dust and storm water as well as monitoring groundwater and other requirements. DEP went on to say the agency “has and will exercise its authority to inspect these facilities to ensure compliance, investigate citizen complaints, and take enforcement action as necessary.” Continue reading

December 20, 2016-by John Blair valleywatch.net editor

On December 16, Vectren Corporation the monopoly electric utility that serves much of southwest Indiana released is latest Integrated Resource Plan outlining its plan to meet their electric customers’ power needs twenty years ahead to 2036. The plan was met with praise from Valley Watch and others who care about the enormous level of coal pollution in the Tri-State region centered in Evansville. 

This is the timeline that Vectren proposes for retiring much of their coal fleet. Screen Shot from Vectren IRP

In brief, Vectren proposes to retire three of their four wholly owned coal units by 2024 and to “exit” its contractural operating agreement with Alcoa in Warrick County on a coal unit there. They also announced their intention to build a new Combined Cycle natural gas plant to make up for the lost generation capacity by shutting down the coal units.

A Terrifying Superbug Just Showed Up on a US Farm for the First Time

The bacteria found in a hog operation is resistant even to some of our most powerful antibiotics.

December 7, 2016 – by Tom Philpott in Mother Jones

More than 70 percent of the antibiotics consumed in the United States go to livestock farms, one of the main triggers driving a rising crisis of antibiotic resistance in human medicine.

On Tuesday, researchers from Ohio State University published an alarming findingin a peer-reviewed journal: On a US hog farm, they found bacteria that can withstand a crucial family of antibiotics. Carbapenems, as they are known, are a “last line of defense” against bacterial pathogens that can resist other antibiotics, the paper notes. Worse still, the gene that allowed the bacteria to resist carbapenems turned up in a plasmid—small chunks of DNA found in bacterial cells. Plasmid-carried genes bounce easily from one bacterial strain to another, meaning that carbapenem resistance is highly mobilemaking it more likely to find its way into bacterial pathogens that infect people.

If this news sounds depressingly familiar, it’s because something very similar happened with another last-ditch antibiotic, colostin. About a year ago, Chinese researchers alarmed global public health authorities when they found a “plasmid-mediated” strain of colistin-resistant E. coli on a Chinese hog farm. As predicted, it quickly went global, and it turned up in the United States in a patient in May, as well as in a pig intestine identified by US Department of Agriculture researchers. In September, Rutgers and Columbia University researchers found a strain of E. coli with plasmid-carried resistance to colostin and carbapenems. The new Ohio State study marks the first time plasmid-borne carbapenem resistance has been found on a US farm, though it has turned up in livestock operations in Asia and Europe, the researchers write.

Air pollution is not only causing long-term damage to the planet and human health, but it is already killing millions of people worldwide. In an editorial published November 14, 2016 in STATDavid Hunter, Vincent L. Gregory Professor in Cancer Prevention at Harvard T.H. Chan School of Public Health, and Francesca Dominici, professor of biostatistics and senior associate dean for research, call for actions that would mitigate climate change in the future—and alleviate the immediate health burdens from air pollution.gas mask

One in eight deaths worldwide each year is linked to air pollution, according to the World Health Organization. This translates to approximately 7 million people—far more than the number of deaths due to HIV/AIDStuberculosis, and malaria combined. In addition, air pollution contributes to disabling conditions in millions of people including asthma, chronic obstructive pulmonary disease, and heart disease and stroke.

Cutting back on burning fossil fuels and biomass would have immediate health benefits, and also meet climate change mitigation goals, the authors wrote. They urge delegates at the United Nations convention on climate change in Marrakech this month, and the incoming U.S. administration, to take this into consideration. “Even climate change skeptics who deny the scale of future environmental impact should not tolerate of the millions of deaths currently caused by air pollution today,” they wrote.

This is where we live. Do you know someone with cancer, or maybe its a heart attack or a stroke. It could be just a chronic but life threatening condition like asthma. Or, as recently studies have indicated, air pollution induced Alzheimers disease.

Whatever it is, the reason could well be the enormous level of pollution we are forced to breathe each day just so other places can flip the switch and completely lack the understanding that they are causing us severe health problems.

Kentuckians can handle the truth, the coal truth and nothing but the truth

October 28, 2016 – Editorial in the Lexington Herald Leader

Give Gov. Matt Bevin’s environmental secretary credit. When asked about the prospects for Eastern Kentucky’s coal industry, he was honest — unlike all the misleading political ads and mailings that are bombarding Kentuckians.

What Secretary Charles Snavely said was important, but how he prefaced it is even more enlightening in this election season.

When asked by a lawmaker at a meeting in February if there is hope for a coal-industry rebound in Central Appalachia, Snavely said, “I regret you ask me that question in a public forum because if you ask me a question, I’m going to give you the answer.”

OK. He seems to be saying Kentuckians can’t handle the truth. But why? What myth is it so important to perpetuate?

Snavely, a mining engineer and former coal-company executive, went on to say that he sees no rebound for Eastern Kentucky’s coal jobs anytime soon.

He based his prediction on world economic conditions, cheap natural gas and an uncertain regulatory environment that discourages electrical utilities from building new coal-fired capacity.

Plus, thermal (the kind for power production) coal from Eastern Kentucky has a unique market disadvantage. Because the remaining seams are thin, it costs more to mine, which means it can’t compete on price with coal from other regions, including the Illinois Basin, Wyoming, Montana and even Northern Appalachia — all of which produce cheaper coal than Eastern Kentucky.

That honest opinion from a Republican governor’s appointee echoes what a utility executive told the Kentucky Governor’s Conference on Energy and Environment in Lexington last month.

Natural gas is expected to overtake coal this year as the country’s No. 1 source of power and could continue to underprice coal for the next 20 to 50 years. Kentucky Power chief Greg Pauley said that because natural gas and wind energy are “the price winners,” demand for coal isn’t coming back “no matter who is elected in November.” Continue reading

After nearly thirty years, Evansville Courier Press recognizes the need for safe air in SW Indiana

October 9, 2016 – by the Editorial Board of the Evansville Courier Press. Editor’s Note: Valley Watch has tried many times over the years to get the Evansville Courier & Press to look at the facts regarding the behemoth power plants located in the area and their relationship to  the region’s poor health performance. Finally, after  recent reports by the Center for Public Integrity, The Weather Channel and USA Today, The ECP published this editorial on October 9, 2016AEP Rockport 2

EDITORIAL

Indiana needs to clean air polution 

We seldom are trendsetters in Indiana. And for the most part that’s OK. But sometimes our reluctance to accept change has serious consequences, including harming our health and our quality of life.

That’s certainly been true with our slow, downright stubborn, refusal to more aggressively cut our dependence on coal as our primary fuel source for generating electricity.

Nationwide, coal is used to produce only 33 percent of the electricity consumed in America’s homes and businesses. In Indiana, we still burn coal to generate about 85 percent of our electricity. Only three states — West Virginia, Kentucky and Wyoming — are more dependent than Indiana on coal.

To hear Indiana’s top political and business leaders tell it, the state has little choice but to continue its heavy reliance on coal. To do otherwise, they say, would risk wrecking the state’s manufacturingdependent economy because the cost of electricity would surge.

Perhaps. But then why have neighboring states such as Ohio and Michigan, also centers of manufacturing, been able to significantly reduce their reliance on coal? Is Indiana’s economy really less able to adapt to change than our neighbors?

Those questions arise out of an enlightening new investigation by the Center for Public Integrity, the USA TODAY Network and the Weather Channel. Their report found that about one-third of all industrial air pollution in the United States is produced at 22 sites. Four of them, all coal-fired power plants, are in southwest Indiana, near Evansville. The health consequences for Hoosiers, and for our neighbors in other states, are serious. Air pollution significantly increases the risk of cancer, heart attacks and respiratory illnesses, such as asthma.

So yes, the average cost for electricity is a bit cheaper in Indiana than in Ohio — 11.33 cents per kilowatt hour versus 12.47 cents. But how much do we lose from higher health care costs and insurance rates? How many years of productivity are lost because workers are burdened by chronic illnesses?

Even more important, how many lives have been cut short because our state has been slow to further reduce air pollution? Continue reading

Valley Watch president, John Blair addresses a rally on coal ash in Louisville six years ago today

September 28, 2016 – by John Blair, valleywatch.net editor.

Six years ago today, a hearing was held in Louisville to take testimony from the public on whether to regulate coal ash. Today, the rule is being implemented and should go far in making areas around coal plants safer for people to live and work. 

This video shows me, John Blair, speaking to a rally on the steps of EON, the parent company of Louisville Gas & Electric Company.

Air pollution from power plants may be linked to Alzheimers Disease, others

September 5, 2016 – by Damian Carrington in TheGuardian

Toxic nanoparticles from air pollution have been discovered in human brains in “abundant” quantities, a newly published study reveals.

The detection of the particles, in brain tissue from 37 people, raises concerns because recent research has suggested links between these magnetite particles and Alzheimer’s disease, while air pollution has been shown to significantly increase the risk of the disease. However, the new work is still a long way from proving that the air pollution particles cause or exacerbate Alzheimer’s.

“This is a discovery finding, and now what should start is a whole new examination of this as a potentially very important environmental risk factor for Alzheimer’s disease,” said Prof Barbara Maher, at Lancaster University, who led the new research. “Now there is a reason to go on and do the epidemiology and the toxicity testing, because these particles are so prolific and people are exposed to them.”

Air pollution is a global health crisis that kills more people than malaria and HIV/Aids combined and it has long been linked to lung and heart disease and strokes. But research is uncovering new impacts on health, including degenerative brain diseases such as Alzheimer’s, mental illness and reduced intelligence.

The new work, published in the Proceedings of the National Academy of Sciences, examined brain tissue from 37 people in Manchester, in the UK, and Mexico, aged between three and 92.

It found abundant particles of magnetite, an iron oxide. “You are talking about millions of magnetite particles per gram of freeze-dried brain tissue – it is extraordinary,” said Maher.

“Magnetite in the brain is not something you want to have because it is particularly toxic there,” she said, explaining that the substance can create reactive oxygen species called free radicals. “Oxidative cell damage is one of the hallmark features of Alzheimer’s disease, and this is why the presence of magnetite is so potentially significant, because it is so bioreactive.”
