Frozen Towns "Experiment" With Salt Replacements

Shouldn't public officials be the ones to think about the long-term consequences of decisions like this?

Soaring rock-salt prices are prompting communities across the U.S. to try novel alternatives for clearing snow and ice, including molasses, garlic salt and a rum-production byproduct that smells like soy sauce.

Rock-salt prices normally surge in January and February, when communities running low on salt resort to buying the de-icing compound on the open market. But after last year's fierce winter taxed supplies, state and local government officials ordered tens of thousands of tons more salt ahead of this season. The high demand pushed salt prices to $60 to $120 per ton in many places, from last year's range of $30 to $50 a ton.

The jump in prices comes as communities are struggling with budgets tightened by shrinking tax revenue, thanks to the recession. The current bout of winter weather, which already has battered cities and states nationwide, threatens to strain budgets even more.

But wait, what do we have here? They're using "non-toxic" ash from coal-fired power plants as a mixture, the same ash we established as toxic just a few days ago. When the roads dry up and all those particulates get kicked up into the air, you don't suppose people might, oh, I don't know, inhale them?

Many towns are testing new methods to make their ice-fighting more efficient. Officials in Indiana and other states are equipping salt trucks with computers that, based on current air and ground temperatures and other metrics, tell drivers how much salt to drop and for how long.

This past summer, engineers in Ohio's Hamilton County sought bids to supply about 15,000 tons of salt. The county rejected the first set of bids, which were about 50% higher than the $40 a ton the county paid last year. Two more rounds resulted in quotes of as much as $157 a ton, which would have exceeded the county's entire $1.5 million budget for snow and ice removal, said Ted Hubbard, the chief deputy county engineer.

The county decided to try to make the 11,000 tons of salt it had on hand last for a winter of de-icing 1,500 miles of road lanes. To stretch it, Mr. Hubbard's department has been mixing its salt with gritty, non-toxic ash left over from coal-fired power plants.

"When the sun shines on it, it helps attract radiation, therefore it helps melt the snow," Mr. Hubbard said. "We're sort of experimenting." Mr. Hubbard said the ash mixture doesn't melt the snow as fast, but it does add traction to the roads.

"Sort of experimenting." Yeah, you could say that.

Everything the EPA Never Wanted You To Know About Ash Toxins

Well, my goodness. It looks as though the people in the path of that massive ash spill are going to be, um, immunologically challenged!

Yes, despite offical assurances, it turns out there's all kinds of nasty stuff in the sludge. And surprise, surprise - the EPA knew, because they'd already released a study:

The risk assessment examined 181 coal combustion waste disposal sites throughout the country and found that unlined coal ash waste ponds pose a cancer risk 900 times above what the government considers "acceptable." The report also found that coal ash disposal sites release toxic chemicals and metals such as arsenic, lead, boron, selenium, cadmium, thallium, and other pollutants at levels that endanger human health and the environment.

"Clean" coal, huh?

Coal Ash Spill is Much Larger Than First Described

The environmental disaster first disclosed a few days ago is growing much bigger than authorities described:

A coal ash spill in eastern Tennessee that experts were already calling the largest environmental disaster of its kind in the United States is more than three times larger than initially estimated, according to an updated survey by the Tennessee Valley Authority.

Officials at the authority initially said that about 1.7 million cubic yards of wet coal ash had spilled when the earthen retaining wall of an ash pond at the Kingston Fossil Plant, about 40 miles west of Knoxville, gave way on Monday. But on Thursday they released the results of an aerial survey that showed the actual amount was 5.4 million cubic yards, or enough to flood more than 3,000 acres one foot deep.

The amount now said to have been spilled is larger than the amount the authority initially said was in the pond, 2.6 million cubic yards.

But don't worry, we don't know for sure that it will kill the victims:

Mr. Moulton said on Friday that the levels exceeded safety limits for drinking water, but that both metals were filtered out by water treatment processes.

Mercury and arsenic, he said, were “barely detectable” in the samples.

The ash pond was adjacent to the Emory River and near a residential area, where three houses were destroyed by the tide of muddy ash. Water sampled several miles downstream from the spill was safe to drink, but its iron and manganese content exceeded the secondary drinking water standards set by the Environmental Protection Agency, which govern taste and odor but not potential health effects, Mr. Moulton said.

Neither the authority nor the E.P.A. has released the results of tests of soil or the ash itself. Authority officials have said that the ash is not harmful, and the authority has not warned residents of potential dangers, though federal studies show that coal ash can contain dangerous levels of heavy metals and carcinogens.

“You’re not going to be endangered by touching the ash material,” said Barbara Martocci, a spokeswoman for the T.V.A. “You’d have to eat it. You have to get it in your body.”

The Tennessee Department of Environment and Conservation also released a statement saying there was no indication of risk unless the ash was ingested.

"Ingested." You mean, as in "inhaled"? Because it seems to me it will be almost impossible for residents to avoid breathing it in. Oh well. Thanks, BushCo!

I hope the new Democratic Congress and the corporate media continue to do their bit for more "clean coal"!
