From NOAA:

...WIDESPREAD HEAVY RAINFALL POSSIBLE FROM LATE TONIGHT THROUGH WEDNESDAY MORNING...

.A STRENGTHENING LOW PRESSURE SYSTEM OVER THE LOWER MISSISSIPPI RIVER VALLEY WILL SPREAD WIDESPREAD RAINFALL OVER THE REGION TONIGHT. SOME OF THIS RAINFALL MAY BE HEAVY AT TIMES BEGINNING AFTER MIDNIGHT TONIGHT...AND CONTINUING THROUGH WEDNESDAY MORNING. BY WEDNESDAY MORNING...WIDESPREAD TOTAL RAINFALL AMOUNTS OF THREE TO FOUR INCHES WILL BE POSSIBLE ACROSS MOST OF THE WATCH AREA.

Has anyone else noticed that NOAA is pronounced "Noah"? This kind of rain is exactly what we don't need. A group of TCWN folks and I toured the spill area today and saw lots of water backed up in the coves. Here's hoping the amphibious excavators got channels cut through the ash piles that are blocking the normal water flow out of the coves. If not, it could complicate the cleanup by pushing ash further down the lake.

Trenches mostly cut...

...perhaps finished by this hour. Pumps in place 3 different places that can pump about 8K gal/min.

To where are the pumps going to pump ?

Good Questtion. If Rb doesn't know i guarantee he will find the answer for you.

Lala - you're way too kind :-)

I THINK they will pump back from the slews/or sludge filled slews out into the river channel.

RB

The idea is to prevent the slews which are backed up by the sludge for silling up and breaking through the sludge dams and creating a mass flow of sludge filled water out into the main channel. The pumps are intended to take rainwater past the sludge dams into the regular main channels and relieve the pressure until a new channel can be cut to restore normal flow. As of my tour yesterday, there were several feet of water backed up into the slews.

Exactly, WC...

... That's why the folks working for TVA were still working on that issue last night, in anticipation of the rain. Fortunately, the worst that could have happened rain-wise didn't. Hopefully it won't. But we're not out of the woods yet.

RB

OK, I understand

Ok, I understand a little better now. It is the diversion that was not quite clear. You know how inquiring minds simply want to know.

The idea is to prevent the

O, I see. The plan is to bypass all the controls for keeping more ash plumes out of the Emory River and put it directly into the river. Brilliant! Now it can be truthfully said that TVA is intentionally polluting the river with more coal waste runoff. Does anybody have the email address for Erin Brokovich or Bobby Kennedy? I can't wait to tell them this. Or maybe I should tell Sierra Club they just filed this notice:

Massive Coal Ash Spill Leads to Challenge of Tennessee Valley Authority

Local Residents, Environmental Advocates: “Coal is Not Clean”

Knoxville, Tenn.: A coalition of local residents and environmental groups has put the Tennessee Valley Authority (TVA) on notice today for its negligence surrounding the tragic December 22 coal ash spill at the Kingston Fossil Plant in Roane County, Tennessee. In collaboration with dozens of neighbors whose property was directly affected by the spill, the groups Appalachian Center for the Economy and the Environment, Earthjustice, Public Justice, and Sierra Club are requesting that a federal court oversee the cleanup and remediation and that the responsible parties compensate local residents.

“This catastrophic spill was a colossal tragedy, and the Tennessee Valley Authority could have avoided this disaster had it taken its responsibilities seriously,” said Bruce Nilles, Director of Sierra Club’s National Coal Campaign. “This massive spill reminds us that coal is not clean, and coal is not cheap.”

On December 22, 2008, an earthen dam for a coal ash waste impoundment failed at the Kingston Fossil Plant, releasing hundreds of millions of gallons of coal ash sludge and contaminated water into the Emory and Clinch Rivers and onto more than 300 acres of nearby land. Most of this potentially toxic waste remains in or near those waters. The spill left behind piles of coal ash waste that will continue to leach and channel toxic chemicals into those two rivers and other groundwater whenever it rains.

Environmental Protection Agency (EPA) testing found more than 100 times the maximum Arsenic level allowed by the federal government in the Emory River near the spill site. The metals in this coal ash sludge may also become airborne as particulates when the ash dries out.

“We need to remember that TVA operates ten other coal-fired power plants, each with its own ash waste disposal problems,” said Axel Ringe, Sierra Club Tennessee Chapter Vice Conservation Chair. “Although TVA deservedly gets primary blame for this disaster, all the agencies involved must improve the oversight and permitting processes.”

The Tennessee River is the source of drinking water for the City of Kingston, Tennessee, and the Watts Bar Reservoir downstream is used by several communities for their drinking water supply. This poses a substantial health risk to persons who consume contaminated water, eat contaminated fish, or breathe airborne dust.

“We are talking about an environmental crisis of epic proportions,” said Earthjustice attorney Lisa Evans, who is representing Sierra Club in the case. “Not to mention the slow-motion disaster taking place at coal ash dumps all over the country, where 130 million tons of this toxic waste pile up each year and threaten to seep into drinking water supplies.”

“This spill has contaminated the land and water near the spill and threatened the health of dozens of families who own property, use the river, and breathe the air near the plant,” says Mary Parker, a Nashville attorney (and former President of Public Justice) who is representing dozens of local residents whose property is affected by the spill. “The TVA needs to clean up this mess and compensate the residents for their losses.”

The groups sent the TVA a formal notice of intent to sue today. The Sierra Club is represented by Joe Lovett with the Appalachian Center for the Economy and the Environment, Jim Hecker with Public Justice, Lisa Evans and Deborah Goldberg at the nonprofit environmental law firm Earthjustice. Mary Parker at Parker & Crofford represents the local residents.

The Sierra Club's National Coal Campaign is working to ensure coal is mined responsibly, burned cleanly and does not contribute to global warming. This involves addressing the entire coal cycle, including mountaintop removal mining and its devastating impact on communities. Sierra Club supports efforts to invest in clean energy solutions. This coal ash spill is a painful reminder that there is no such thing as “clean coal.” For more information, visit (link...).

The plan is reasonable and sound given the mess we're in. It is to allow the water to flow out of the slews through the spill, yeah some of it will move down stream but nowhere near what would move if the dam formed by the ash cloggin the stream channels in the slews were to back up, overflow, and burst.

This stuff takes time. I looked at the short term plan and I think it is sound within the limits of what can humanly be done.

Having said all that, I fully support a move to require the true costs of coal to be invested up front. We are laboring under the mistaken perception that coal provides cheap energy and that's simply a myth if you count the cradle to grave environmental costs. Part of the settlement should include a rational plan to phase out coal as an energy source within a very short term.

WhitesCreek: "The plan is reasonable and sound given the mess we're in. It is to allow the water to flow out of the slews through the spill...."

And as it flows through the spill it will pick up more coal waste. So the plan is to intentionally route the water through the contaminated spill zone rather properly routing it to sediment and erosion control BMP's.

It should be routed through a wet detention BMP, where it won't collect more pollution. The plan is the opposite of reasonable. It is a method that intentionally pollutes the river with more coal waste.

Like there's time...

... with all this rain coming down to do anything other than a quick fix right now... right...

That is the problem with

That is the problem with human made disasters that could have been avoided. We are all left with very poor choices and and those poor choices often lead to rushed actions that make the situation worse rather than better.

By the way, where is TVA putting the waste they are cleaning up? Could it be they are putting back into yet another unlined earthen dam structure?

Oh wait, first I should ask if they have cleaned up any of the solid coal waste from the river yet? Or are they still working on clearing the railroad track so they burn more coal and make more coal combustion waste (CCW)?

Why don't you wave your

Why don't you wave your magic wand and make one of those things happen for us?

Frankly, as long as the water flowing through the ash is alkaline, the problem is minimized to the extent it can be for now.

I don't mean to say it's nonexistent. Anyone who looked at the situation knew this was going to happen as a result of the original event. the flow is channelized which will expose it to minimal new ash and hold leachate as low as possible. Some further leaching will happen but I'm comfortable with what is being done as the best possible at this point in time. It simply takes time to transport the massive equipment that has to be pulled off other jobs and get trained operators in place with a coherent operating plan.

A better question might be,

A better question might be, why didn't TVA make it happen? They are responsible for cleaning up the tragic mess they made. Maybe magic wands may exist in the fondly remembered fairy tales of childhood, but they don't exist in the real world.

I honestly would like an answer to my very simple question: How many loads of solid coal waste have been removed from the Emory River?

WRK

I totally agree that there's fault to be placed. I've done that myself..

But right now, we have to make sure that there's no blowout of the spill caused damming of the coves and slews. I love alligators and am against draining swamps, but there's an analogy you might give some though to.

We share common goals, but differ at this point on how to achieve them.

Hmmmm...I thought everyone's

Hmmmm...I thought everyone's goal was to clean up the mess as quickly and as safely as possible. Routing rainwater through the ash where it picks up more contaminates and then intentionally pumping it to the mainstem of the river bypassing containment structures doesn't achieve the goal of cleaning up the mess as safely as possible. It simply adds more coal ash waste to river.

The issue is more than clean-up...

... Based on hydrologists' predictions of possible river stages and flooding today, the issues enlarged to include imminent flooding and preparations to prevent that. So what if there was no place for runoff to go (no trenches to river)? And the water level rose several feet? And people whose land was covered with fly ash sludge experienced the water rise to levels that now the fly ash directly contaminates their wells when it hadn't before? That would only create MORE issues for somebody to have to clear up, and they would be issues having to do with new health issues that weren't there before.

When flooding is a high possibility, it doesn't matter who made the issues over what period of time. You have to do what is necessary for the short term.

Ever heard the saying "When you're up to your a$$ in alligators, it's hard to remember your primary objective was to drain the swamp."?

It applies here.

RB

Why are you trying so hard

Why are you trying so hard to find fault with what is going on, WRK? If you have something constructive to offer, let's have it. We're open to ideas.

You seem to be intentionally misunderstanding what is going on here.

These coves are the outlets for creeks that are currently swollen with rainwater. They were dammed by the spill and water is backing up behind them. If they are not allowed to flow they will build up until the ash dam eventually breaks and a smaller than the first one but still massive flow of mud will head out to the main channel. In the mean time farms and houses behind the ash dams are being flooded as the backed up water rises.

A temporary channel has to be constructed that will keep the flow in a narrow channel that won't disturb any more ash than necessary. Then it flows into a temporary impondment constructed of the ash and mud that has pipes through it so that the flow out to the main channel is regulated and as much ash as possible can settle out in the temp pond.

It could take a year or more to physically restore the natural channels.
