The salary reduction was blamed partially on a drop in power sales as a result of a slumping economy. But the TVA also did away with performance bonuses for top executives, including Kilgore – a wise move considering the nation’s largest utility is facing millions in lawsuits from residents affected by last year’s coal ash spill and at least $1 billion more from a massive cleanup of the land damaged by the spill.

“It has been a very difficult year,” said TVA chairman Mike Duncan at the utility’s last board meeting.

The TVA says Kilgore took the biggest hit in salary reduction among staff at the utility, and now earns 45 percent less than the average top executive at other utilities, according to a study conducted by the TVA. Kilgore receives a base salary of $875,000 per year plus a $300,000 annual retention bonus for the next four years.

While a handful of top executives will have to forgo performance raises this year, the remaining 12,000 TVA staffers are still eligible for raises in 2010.

The TVA reported to the U.S. Securities and Exchange Commission that it earned $726 million on revenues of $11.3 billion during fiscal year 2009, compared to $817 million on revenues of $10.4 billion the previous year.

Several years ago coal ash from power plants was given a non-hazardous rating. Since then, technology has improved the quality of the smoke released into the air from coal-firing plants. The toxins that used to escape into the air are now kept in the ash left behind. Tests have shown that coal ash contains dangerous toxins such as arsenic, lead, chromium, manganese and barium, which have been linked to serious health conditions such as cancer, liver damage and neurological complications.

Environmentalists have tried over the years to have coal ash reclassified as a hazardous material, but little was done to push that effort until last year when a coal impoundment pond in east Tennessee breached, sending a massive wave of coal ash on to a neighboring community. The 1.1 billion gallons that spilled out toppled houses, destroyed property and contaminated the nearby Emory River. Several residents were displaced, but it is the health risk that concerns many of the people affected by the spill. Some have reported respiratory problems and heightened anxiety. Others, including a young child, have tested positive for heavy metal in their bloodstream.

Environmentalists and activists are urging the EPA to carefully consider how it will categorize both wet and dry coal ash impoundments. “Both pose a threat to human health and the environment so it doesn’t make sense to create that dichotomy (between wet and dry ash storage regulation),” said Lisa Evans, an attorney with Earthjustice, in an interview with the Tennessean.“We would not think that would be a protective scheme, with the many cases where dry disposal has caused contamination of groundwater and surface water.”

Indiana

An investigation into the cause of the TVA spill has sent a ripple of new standards for coal ash impoundments throughout the country, including a survey conducted by the EPA of all electric utilities. The EPA found nearly 600 ash ponds. The most ponds were found in Indiana, with 53 ponds. Kentucky came in close second with 44 ponds. The survey also found significant deficiencies in the way some of the impoundment ponds have been inspected, though which ponds and where were not disclosed.

In 2000, the EPA deemed coal ash a nonhazardous material, and thus it did not fall under federal inspections. Inspections are left up to state regulators. Since 2000, improved pollution controls keep more and more toxins from leaving smokestack, thus increasing the amount of toxins in the coal ash. Coal ash contains arsenic, lead, chromium, manganese and barium, all of which have been shown to contribute to serious health conditions such as cancer, liver damage and neurological complications.

The Obama administration has promised to adopt national standards for the handling of coal combustion wastes including coal ash ponds, though no time line has yet been set. The EPA says it will analyze the findings of the survey. A report will be made public by the first of next year.

“If these sites are so hazardous and if the neighborhoods nearby could be harmed irreparably, then I believe it is essential to let people know,” said Senate Environment and Public Works Chairwoman Barbara Boxer, in a letter to three different executive-branch agencies. “In that way, they can press their local authorities who have responsibility for their safety to act now to make the sites safer.”

The EPA, which is now overseeing coal ash ponds around the country, first refused to reveal the sites after an April House committee hearing. Last week, Boxer held a press conference to say that the EPA had once again to refused publicly identify where those impoundment ponds are located.

Coal ash contains dangerous toxins such as arsenic, lead, chromium, manganese and barium, which have been linked to serious health problems such as cancer, liver damage and neurological complications.

More than 125 million tons of coal ash combustion waste is produced in power plants in the United States and most of it is stored in dry landfills or above-ground coal slurry ponds. In 2000, that material was classified by the EPA as non-hazardous and thus was exempt from government regulations. Since then, improved pollution controls have kept toxins from leaving smokestacks but have made the coal ash even more dangerous. Yet, the coal ash plants have evaded regulation. The December coal ash spill at Kingston has shown how serious and disastrous a coal ash spill can be. As a result, the EPA is taking steps to regulate the coal ash industry. But critics, like Boxer, say the EPA should be more forthcoming about the information it obtained.

“The public’s right to know about threats in their communities is critically important,” she said.

Cancer rates

The EPA screening study conducted in 2002 was not made public until March 4, 2009. Numerous attempts to get the information made public through the Freedom of Information Act to the EPA during the Bush Administration were denied or released with the risk estimates blacked out. The data finally made public after seven years shows that cancer risk is substantially higher for up to one out of every 50 Americans living near wet ponds used to dispose of ash and scrubber sludge from coal-fired power plants across the United States.

The analysis focuses on 100 landfills and 110 surface impoundments examined by the EPA that lack effective synthetic liners to prevent leaks as the EPA found unlined and clay-lined waste units present far greater risks to both human health and ecosystems. These high-risk coal ash dump sites are in more than 35 states.

According to the report: “Can living next to one of these dumpsites increase your risk of getting cancer or other diseases? The U.S. Environmental Protection Agency (EPA) thinks so, especially if you live near one of those wet ash ponds, or surface impoundments, that dot the landscape near large coal plants, the pond has no protective liner, and you get your drinking water from a well … (N)earby residents have as much as a 1 in 50 chance of getting cancer from drinking water contaminated by arsenic, one of the most common, and most dangerous, pollutants from coal ash. And that’s not all. That same risk assessment says that living near ash ponds increases the risk of damage to the liver, kidney, lungs and other organs as a result of being exposed to toxic metals like cadmium, cobalt, lead, and other pollutants at concentrations far above levels that are considered safe. In addition, the danger to wildlife and ecosystems is simply off the charts, with one contaminant—boron—expected to leach into the environment at levels two thousand times thresholds generally considered to be safe.”

However, the method for the regulation of coal ash has come under scrutiny after a Tennessee Valley Authority (TVA) impoundment pond failed last December and dumped more than a billion gallons of coal ash sludge over 300 acres of an east Tennessee community, destroying homes and damaging property in its wake. Both residents and environmentalists began asking questions about the toxic material that had poured into the neighboring Emory River and heaped as much as nine feet high in some areas.

Since 2000, improved pollution controls have kept toxins from leaving smokestacks and thus have increased the amount of toxins in coal ash, says Rhon Jones, Toxic Torts Section Head with Beasley Allen law firm. The material may contain arsenic, lead, chromium, manganese and barium which can contribute to dangerous health conditions such as cancer, liver damage and neurological complications, to name a few.

Many residents in the area already have complained of respiratory problems and half reported experiencing increased stress and anxiety. “In addition, EPA has improved testing which reveals toxins are leaching into groundwater more than originally thought,” Jones adds.

To date, EPA has found groundwater contaminated with heavy metals from coal ash dumps at 63 sites. An independent report asserts that nearly 100 coal ash dumps across the United States pose similar or even greater potential dangers than the TVA Kingston plant, Jones says.

“On March 9, 2009, EPA sent a survey to the 163 utilities that manage approximately 300 coal ash ponds in the U.S. The survey calls for plant operators to provide information about coal ash pond design, engineering, and inspections and to list any spills or unauthorized releases within the last decade. While a step in the right direction, EPA’s survey does not ask for information on whether the coal ash ponds are lined, whether the ponds have water collection systems to catch toxins leached from the ash, or whether groundwater monitors are in place near the ponds,” Jones says.

After survey results are reviewed, EPA plans to follow up with on-site visits and order improvements where the ponds are found to be unsafe.

In response to the December 22, 2008 coal ash spill in Kingston, Tennessee, the EPA committed to propose new regulations governing coal combustion waste by the end of 2009. The EPA also committed to act immediately to prevent accidents such as the TVA spill in Kingston.

“The Kingston, Tennessee, spill and others like it show the need for strict standards on how this waste is disposed. In addition to EPA’s renewed interest in regulating coal ash disposal, the U.S. Congress is looking into the spill,” Jones says. “Hopefully, these actions by EPA and Congress will either increase safety near these facilities, require alternative methods of disposal, or both.”

The engineers concerns about the stability of the pond walls are detailed in documents released earlier this year by the TVA. The documents were requested by the Tennessee Department of Environment and Conservation (TDEC) in an effort to pinpoint why the pond breach occurred in the first place.

The documents show that the dikes making up the coal ash pond were in frequent need of maintenance and re-engineering. TVA officials made decisions based on opinions of both in-house engineers and consulting engineers. The pond’s most recent stability inspection – which showed nothing that would indicate failure – occurred just two months before the spill.

So far, the utility has spent more than $68 million cleaning up the mess, and that cost is expected to rise to as high as $825 million. The utility also has spent $11 million to buy out property from locals affected by the spill. Additional expenses are expected to cover litigation, penalties and settlements.

The TVA launched a massive cleanup effort which includes dredging the Emory River to remove the ash and spreading grass seed over the affected land to keep the ash from flying about. The cleanup operation is costing the TVA about $1 million per day and is expected to ring in between $525 million and $825 million before the cleanup is complete and the land is restored.

The TVA also admitted publicly that it should have been more forthcoming about the possible dangers of the coal ash from the beginning. Since then, the utility has made efforts to keep the public informed of cleanup efforts through community meetings and the media.

Regardless, the cleanup has come under scrutiny by both environmental groups and community members who want more oversight and environmental studies performed.

The spill caught the attention of lawmakers and environmentalists alike, who are debating how such coal ash ponds should be regulated by the government after the disastrous coal ash spill at a Tennessee Valley Authority (TVA) plant in Kingston, Tennessee last December. That spill dumped more than a billion gallons of the toxic sludge onto a rural neighborhood, destroying homes and damaging property in its wake.

The TVA continues to clean up that mess, which could cost the utility between $525 million and $825 million. The effects on wildlife and humans are yet to be played. Coal ash may contain high concentrations of selenium, sulfate, arsenic, iron and manganese which can lead to serious health problems such as cancer, liver damage and neurological complications.

Environmental activists and lawmakers are pushing the government to step up regulation of coal ash plants. In a letter to the Cumberland Times-News, Joy M. Oakes with the National Parks Conservation Association in Arlington, Virginia wrote, “There are about 300 coal waste storage sites in the U.S., many much larger than the ones operated by the New Page Corporation, which currently are not subject to any meaningful federal regulation. New regulations to manage coal waste must avert risks to our health, and the health of our national parks, so that our children and our grandchildren may continue to enjoy these treasured places.”

President

According to Kentucky.com, “The Department of Energy will soon announce whether it will use $1 billion in stimulus funds to resurrect FutureGen, a proposal to create in Illinois the world’s first coal-fired power plant designed to capture and bury carbon emissions underground.” The Bush administration decided against building the plant because it would cost more than $1.8 billion. The Government Accountability Office says that price tag is more like $1.3 billion. Proponents of “clean coal” argue that  not building that plant put the effort back a decade.

Renewable resources are front-and-center with lawmakers these days, after a Tennessee Valley Authority (TVA) coal ash pond failed last December, dumping more than a billion gallons of toxic coal ash sludge on to an east Tennessee community. Previously unregulated by the federal government, coal ash ponds and storage units will soon have to follow standards outlined by the Environmental Protection Agency (EPA) for regulating coal ash.

The economic stimulus plan has $3.4 billion for the coal industry, as opposed to $16.8 billion for renewable energy and efficiency programs. The Obama administration also is says it will implement a program that would cap companies’ carbon emissions.

As part of the campaign, protestors will march Saturday along Palm Canyon in Palm Springs and ask Congress to “quit coal and other fossil fuels and support a clean energy economy,” according to the report. “It is a major source of air and water pollution and leaves in its wake huge, toxic waste piles of ash.”

The protest comes two and a half months after the Tennessee Valley Authority (TVA) Kingston, Tennessee coal ash impoundment failed, dumping 2.2 million pounds of toxic coal ash on to 300 acres of property in rural east Tennessee. Coal ash contains toxins such as arsenic and lead, which contribute to serious health issues such as cancer, liver damage and neurological complications. Residents in the area already have reported experiencing breathing problems since the spill occurred.

The utility is shelling out a million dollars daily to clean up the mess, which destroyed homes and damaged property. Total cleanup costs are expected to ring in between $525 million and $825 million, according to the TVA. The utility also has vowed to convert the coal ash ponds at its Kingston plant to dry ash storage, which will take up to two years to complete.

The Obama administration backed up the promise by vowing to propose new regulations governing coal combustion waste by the end of the year and acting immediately to ensure more dangerous spills do not happen again, according to the New York Times.

The EPA’s Office of Resource Conservation and Recovery is deciding now whether to regulate the waste as hazardous or nonhazardous. In 2000, the material was classified as nonhazardous, but because of better pollution controls, the ash has become more dangerous. Coal ash contains toxins such as arsenic, lead, chromium, manganese and barium. Those materials can lead to serious health problems such as cancer, liver damage and neurological complications.

Residents who live hear the Kingston, Tennessee plant have already complained of breathing problems and some have even tested positive for high levels heavy metal.

TVA is undergoing a million-dollar-a-day cleanup program that is expected to total between $525 million and $825 before it is restored.

The coal industry has long opposed regulation, saying the move will cost billions each year. Activist groups say regulation is necessary to ensure the safety of those living near the plants. EPA has raised concerns from improved tests that show more toxins than previously thought leaching from the ash into groundwater, according to the report.

SOURCE: Coal Ash Spill › Obama administration vows to propose regulations for coal ash

Converting the coal ash ponds to dry ash storage will take about 18 to 24 months to complete. Meantime, TVA will continue working on cleaning up the mess made by the coal ash pond that failed. That cleanup effort is expected to ring in as high as $825 million. TVA has vowed to make the area affected by the spill “as good, if not better than before” the spill occurred. It also will continue to support regulators in the monitoring of water, soil and air.

TVA also is working with state Environment and Conservation for a safe way to remove the ash in the main channel of the Emory River. Once removed, that ash will be temporarily placed on a ball field and at another site at the Kingston plant.

The cleanup will be “developed and reviewed by an interagency team” including the U.S. Army Corps of Engineers, the Tennessee Department of Environment and Conservation, Tennessee Department of Health, the Tennessee Wildlife Resources Agency, the U.S. Fish and Wildlife Service and Roane County officials. TVA also is developing a community involvement cleanup plan.

The practice of utilities selling coal ash byproducts is not unusual. The Tennessee Valley Authority (TVA) recently released a report stating that it sells about a third of the 7 million tons of fly ash, bottom ash, gypsum and boiler slag generated in its plants each year. Those byproducts have been mixed into concrete for roads in bridges and in blocks for buildings. The gypsum has been used in wallboard, granules for roofing shingles and grit for sandblasters. The byproducts even have been used as filler material for recreation areas, ball fields and industrial parks, according to the Atlanta Journal Constitution.

Yes, this is the same type of toxic material that spilled on to 300 acres of rural east Tennessee last December when one of the utility’s coal ash ponds failed, destroying nearby homes and causing hundreds of millions of damage to property. Environmentalists say the damage to wildlife and plant life is still to be determined, and many locals who live near the site have already suffered health problems. The coal ash contains toxins such as arsenic, lead, chromium, manganese and barium, which have been associated with serious health problems such as cancer, liver damage and neurological complications.

So it comes as little surprise that the Chinese drywall containing coal ash byproducts is also making people sick. The lawsuit alleges that the drywall emits one of several sulfur compounds giving homes made of it a foul odor. Some say those fumes also may cause respiratory health problems, headaches, dry eyes and nosebleeds. The long term affects of exposure are yet to be determined.

Other problems caused by the Chinese drywall include corrosion of air condition coils, putting homes at serious risk for electrical fires.

The class action lawsuit names the Knauf Group, PKT’s parent company; Banner Supply, a Miami-based materials supply company; and Rothchilt International, Ltd. , an export company in China. Legal experts believe many more lawsuits will follow.

An Associated Press report found that there are 162 power plants in the county that have coal ash ponds. Those ponds store anywhere from 500 tons to 653,300 tons of coal ash. While coal ash has stayed somewhat below the environmental issues radar, its safety has come into question recently after the December 2008 spill in Kingston.

That spill fell on 300 acres of rural community, destroying houses, damaging property and pouring into nearby rivers. While cleanup efforts are underway, there is much debate surrounding the safety of the land, water and air. Coal ash contains dangerous toxins that can cause serious health concerns such as cancer, liver damage and neurological complications.

The TVA spill has spurred environmental and industry officials in other parts of the country to take a closer look at coal ash ponds at other sites. According to the Gillette News Record report, industry officials in Wyoming say coal ash ponds there are not in jeopardy of leaking or spilling, adding that the TVA incident likely was the result of bad engineering and not the lack of federal regulation.

Despite the reassurance, the Environmental Protection Agency (EPA) has vowed to study the issue and decide whether regulation is necessary. Environmental groups continue to argue that regulating the giant toxic ponds are a must for human safety.

“It was a catastrophe,” said Tom Kilgore, TVA president, referencing an internal memo that was obtained by the Associated Press that downplayed the incident by changing the description from “catastrophic” to “sudden, accidental.” The memo was also edited to remove references of a public health risk, instead choosing to call the spill an “acute threat” to fish.

The spill has caused heartache to both the TVA and residents in the area. When the December coal ash pond spilled over, it destroyed homes and damaged property. The environmental damage has yet to be determined. Several property owners have filed suit against the utility and just last week, TVA announced that its has cut incentive programs for all employees, including senior management. TVA also is facing mounting cleanup costs as much as $1 million a day, which is expected to total as high as $825 million. How it will pay for the cleanup is still unclear. TVA said after insurance payments are made it will consider options that include raising customers’ rates.

In an effort to improve its credibility and garner more respect from the communities in which it serves, TVA has hired an outside consultant to lead an investigation into the cause of the massive spill. The utility also is inspecting ash storage areas at its other coal-fired plants, in particular the coal ash ponds like that in Kingston that failed.

SOURCE: Coal Ash Spill › TVA calls coal ash spill disaster a ‘catastrophe’

The coal ash spill is being touted as the worst environmental disaster in TVA’s history. Not only were homes destroyed and property damaged by the massive outpour, the material that was dumped on to the land and flowed into the river contains dangerous toxins that could pose a possible health hazard not only to animals and plants in the area, but also to humans.

A massive cleanup is underway, ringing in at about $1 million per day. Estimates on the total cost of the cleanup could be as high as $825 million. Some environmentalists say it is almost impossible to completely rid the area of toxins, suggesting the spill site be converted to an independent educational and research center. However, TVA officials say they would rather continue to follow the cleanup plan rather than consider turning the damaged land into a research site.

While the proposed legislation is a step in the right direction, activists say it doesn’t solve the whole problem. “The issue of keen importance is fly ash needs to be regulated at the federal level as a hazardous waste,” said Sarah McCoin, a member of the newly formed Tennessee Coal Ash Survivors Network.

The massive spill is considered one of the worst environmental disasters, destroying homes and damaging property. The toll on wildlife, plant life and, ultimately, human life, is yet to be determined. Cleanup efforts are expected to cost TVA between $525 million and $825 million depending on how many times the waste will have to be moved and how fast crews can dredge the Emory River.

How the utility will pay for cleaning up the mess is yet to be determined. TVA officials say insurance should cover some of the mounting costs, but other options may also need to be considered, such as disposing of assets, using debt and raising power rates. The latter option likely will come with some criticism.

Last fall the utility’s board approved a 20 percent electric rate hike – the highest in almost 20 years – due to escalating fuel costs. As a small tradeoff, TVA lowered its fuel charge by 6 percent in January and said it will cut another 7 percent effective April 1, resulting in a savings of about $4 to $9 in TVA residential customers’ power bills.

TVA provides electricity to about 8.8 million million customers in Tennessee and parts of Mississippi, Alabama, Kentucky, Georgia, North Carolina and Virginia, according to the report.

Coal ash contains toxins such as arsenic, lead, barium, chromium and manganese. These toxins have been associated with serious health conditions such as cancer, liver damage and neurological complications. When the coal ash spilled from the Kingston TVA plant, it poured over property and into nearby rivers. While the contaminants are being cleaned from the ground and waterways, some scientists worry that long term effects on wildlife and plant life could ultimately affect human life.

Indiana has 13 coal ash ponds in 13 different counties. The largest, containing nearly 900,000 tons of ash, is located in Gibson County. Gibson is located in the southwestern part of the state and has a population of about 35,000.

Indiana’s coal-fired power plants export about 24 percent of the electricity they generate. Environmentalists have raised concerns about the serious health concerns associated with coal combustion, including asthma, chronic bronchitis, lung cancer, stroke and sudden infant dath syndrome. According to the report, Indiana has the third highest emissions of sulfur dioxide, which has been strongly associated with human deaths.

The Duke tests revealed high amounts of arsenic and radioactive radium in the toxic sludge at the spill site, findings that throw up red flags about the “safety of storing ash” and emphasize the need for caution in the cleanup process.

According to the Nicholas School of the Environment at Duke, water near the site tested fairly clean, with only trace amounts of arsenic present in samples taken two miles downstream from the spill. The sludge and ash, however, contain two radioactive forms of radium, which is highly carcinogenic to humans.

“As the sludge dries out, the ash picked up by the wind as dust will be carried into the atmosphere. Once there, this dust can be inhaled by people, where it can be deposited on the linings of their lungs giving them unwelcome doses of radioactivity and toxic metals,” writes Bill Chameides, Dean of the Nicholas School at Duke.

The possibility of airborne particulates of radium and other toxic substances arising from the sludge is why the cleanup must be conducted with extreme care. It’s also why the presence of some 1,300 coal ash dump sites throughout the country is so dangerous.

Chameides says that the spill and the cleanup effort are “something for the folks in Roane County to think about.” Even more alarming, however, is how the Kingston spill highlights a much broader concern about the safety of coal. These concerns “go well beyond the Kingston plant to all the coal-fired power plants and their coal ash dumping sites throughout the United States,” Chameides writes.

“Is dangerous particulate matter being liberated from them regularly? And if so, what risks might they pose to the people living near these plants?”

A recent article in the New York Times reported that of the 1,300 coal ash dump sites in the U.S., more than 60 had leakage and contaminated the surrounding water.

The government, however, seems to be downplaying the concerns that the Duke scientists raise.

Avner Vengosh, associate professor of earth and ocean sciences at Duke, and graduate student Laura Ruhl collected ash and water samples from part of the Emory River three weeks after the spill occurred.

Their tests of the solid ash samples found significantly higher levels of radium-228 and radium-226 than the EPA reported to have found: 8 picocuries per gram compared with an average of 5-6 picocuries per gram reported by the EPA.

Vengosh and Ruhl also found 95 parts per billion of arsenic in the inlet tested, but lower concentrations downstream. Ten parts per billion is the EPA standard for safe drinking water.

TVA acknowledged the difference between Duke’s radiation and arsenic levels and those recorded by the TVA.

“We still take the Duke report very seriously and will have the site rechecked,” a TVA spokesperson told WSMV of Nashville.

In 2003 and 2006, two small leaks occurred at the Kingston plant, which raised the interest of the Tennessee Department of Environment and Conservation. That agency asked TVA to provide more information about the leaks but did not require a new storage system.

A TVA spokesman says the two smaller leaks were not related to December’s pond failure, and in both cases repairs were made to the ponds to stop the slow leaks. A 2008 inspection report of the Kingston ponds indicated that there were no structural problems with the ponds. However, officials say that the report indicated that TVA was irresponsible for not realizing that the previous spills pointed toward a serious stability problem.

Coal ash ponds are not regulated by the Environmental Protection Agency (EPA) because the EPA doesn’t consider the coal ash to be hazardous material. Federal agents oversee coal mines but don’t regulate the burning power plants. Some experts say states have done a poor job of monitoring the coal ash ponds.

Tennessee Gov. Phil Bredesen said he is working to provide stronger oversight of the coal ash ponds in his state. Other states where TVA has coal ash ponds or landfills include Alabama and Kentucky.
