Ash Pond Breach: Liability and Compensation

When an ash pond embankment gives way and fly ash slurry pours onto fields, homes, roads or into a river, the power plant that owns the pond is liable for the damage without anyone having to prove how the dyke failed. Under sections 15 and 17 of the NGT Act and the polluter pays principle, the plant must compensate people who lost crops, land, livestock, houses or health, remove the ash and restore the land and water. Claims before the NGT can be made within 5 years. The most important work, though, happens in the first few weeks, before the ash is spread around and the evidence disappears.

This guide is for villagers, farmers and fishing communities hit by an ash pond breach, and for plant operators who want to understand their exposure. It explains why breaches happen, who pays, how losses are assessed and proved, what the tribunal tends to order, and the mistakes that cost people their claims.

It sits under our main guide on thermal power and fly ash pollution. If ash is being trucked out and dumped rather than escaping from a pond, read fly ash dumping rules and complaints.

The essentials

An ash pond breached and flooded our fields. Who is liable?

The power plant that owns the ash pond. An ash pond is part of the plant's own waste disposal system: the plant decided where to build it, how high to raise the dykes, how much slurry to pump in and how to maintain it. When it fails, the plant answers for what flows out. A breach is an accident in the sense of section 17 of the NGT Act, so the tribunal applies the principle of no fault, and section 20 requires it to apply the polluter pays principle.

That means you do not have to prove that the dyke was poorly built or that warnings were ignored, although proof of that strengthens the case and affects how the tribunal views the plant. You have to show that the breach happened, that the slurry came from that pond, and what damage it did. Usually the first two are not disputed. The fight is about the third.

If the pond was operated by a contractor, or the plant blames heavy rain, the plant's liability to the villagers does not change. Rain is the reason ash ponds must be designed with freeboard and spillways in the first place. Whether the plant can recover money from its contractor is its own business.

Why do ash ponds breach?

Ash ponds are large earthen enclosures into which ash is pumped as slurry. The water drains or evaporates and the ash settles. Over the years, as the pond fills, plants often raise the embankments in stages, sometimes building the new dyke partly on settled ash. Each raising adds load, and an embankment that was stable at one height may not be at the next.

The common triggers are heavy monsoon rain that overtops the dyke, seepage that weakens the embankment from inside, poor drainage of decant water, overfilling because the plant is short of disposal space, and lack of maintenance on old ponds that are no longer in active use. The fly ash utilisation notification pushes plants to empty legacy ponds over time, but until that happens the old ponds remain a risk.

Villagers living near a pond often see the warning signs first: wet patches and seepage at the foot of the dyke, cracks, slumping slopes, grey water leaking into fields. If you see these, complain in writing to the State Board and the plant, with photographs. If a breach happens later, that complaint is strong evidence that the plant was warned.

What to do in the first weeks after an ash pond breach

Claims are won or lost on what is recorded before the ash is cleared. This sequence works for one farmer or a whole village.

The NGT has taken up some ash pond breaches on its own after news reports. Even then, villagers should file their losses in that case, because the tribunal can only order compensation to people whose losses are before it.

What losses can be claimed, and what proves them?

Each head of loss needs its own evidence. A single lump-sum figure for the whole village rarely survives scrutiny.

Our land is under a foot of ash. Is money enough?

Usually not, and you should ask for restoration as well as compensation. Section 15 covers restitution of property damaged and restitution of the environment, which lets the tribunal direct the plant to remove the deposited ash, restore the topsoil where needed and return the land to cultivable condition, under the supervision of the district administration and the State Board.

Insist on removal rather than levelling. Plants sometimes propose to spread and plough the ash into the soil, which is cheaper and makes the problem look smaller. Whether that is acceptable depends on depth, soil type and what testing shows, and it should be decided by the joint committee with soil testing, not by the plant's contractor on a tractor. Farmers who accept ploughing-in without testing may find yields depressed for years.

Compensation should cover every season the land is out of use, not only the crop that was standing on the day of the breach. If removal and restoration take a year, the claim should include the lost crops for that year, based on the farmer's past yields and current market rates.

The ash has dried and is now blowing into our houses. What can we do?

This is the second wave of harm and it is often worse than the flood. Wet slurry stays put; dry ash lifts in every breeze and settles on houses, food, water stored in open vessels and the crops on fields the breach never reached. Children and older people with breathing problems suffer first.

Ask the State Board and the district administration in writing for immediate dust control: water sprinkling, covering of deposits with soil or sheets, and a removal schedule that starts with ash near houses and schools. Ask for an ambient air monitor in the village while the ash is being handled. Keep doctors' prescriptions for coughs, eye irritation and breathing trouble that start after the breach, because those records support a health claim later.

If removal is slow and the dust continues, that is a ground to go back to the tribunal, or to file if no case is pending, asking for supervised removal with deadlines.

The slurry reached the river. Who can claim for that?

When slurry enters a river or canal, the damage spreads well beyond the villages next to the pond. Fish die, the water turns grey, water supply intakes downstream may have to shut, and fishing communities lose their income. Restoration of the river and compensation for those livelihoods are both within section 15.

Fisherfolk often miss out because their losses are not tied to land records. A fishing cooperative or a village group can apply as a representative body under section 18, with a list of members and their usual catch and income. Records of a fishing society, licences, sale receipts and photographs of the fish kill help.

Ask the State Board to sample water and sediment at several points downstream and to keep sampling over the following weeks. If drinking water supplies are affected, ask the district administration for alternative supply. Our guide on drinking water contaminated by industry deals with that side, and the guide on oil spill compensation covers similar claims by fishing communities.

What does the NGT usually order after an ash pond breach?

The usual first step is a joint committee, typically the State Board, CPCB and the District Magistrate, sometimes with a technical expert on dam or embankment safety, to report on the cause of the breach, the area affected, the losses and the work needed. The tribunal often directs the plant to deposit an interim amount with the DM at an early stage so that relief reaches families without waiting for the final assessment.

Final directions commonly include removal of ash from fields and water bodies on a timeline, restoration of land, compensation to identified victims through the district administration, environmental compensation for damage to the environment, a dyke safety review of all the plant's ash ponds, and conditions on using the breached pond until it is made safe. The tribunal may also call on the State Board to explain why earlier warning signs were not acted on.

Parties can object to the joint committee's report, and villagers should, if their losses have been undercounted or their area left out. Our guide on objecting to a joint committee report explains how. Interim deposits are worth asking for at the first hearing; see our guide on interim relief in the NGT.

Mistakes that weaken ash pond breach claims

The biggest is waiting. Within weeks, ash is cleared from roads, spread on fields, washed downstream by rain or covered by the next crop. Families who did not photograph the damage or get their names on the revenue survey then struggle to prove anything. The second is accepting a small payment with a full and final settlement clause, often handed out in the first days when people are desperate.

Others include claiming a round figure for the whole village with no breakdown, leaving out tenants and sharecroppers who lost crops on land they do not own, ignoring livestock and fishing losses because they are hard to document, and filing only against the plant while ignoring the regulators whose inaction may have contributed.

In ash pond cases Advocate B.K. Singh has worked on, the families who recovered fair amounts were the ones whose losses were recorded field by field in the first fortnight, with khasra numbers and photographs, and who objected promptly when an official survey left them out. Advocacy at the hearing cannot make up for losses that were never recorded.

Is there a deadline for claiming after an ash pond breach?

Yes. A compensation claim under section 15 must be filed within 5 years of the date the cause of action first arose, and the tribunal can allow up to 60 more days for sufficient cause. For a breach, time usually runs from the breach itself, though continuing damage such as ash left on land can raise arguments about a continuing cause. Our guide on NGT time limits explains how these periods are counted.

Five years sounds long, but evidence fades much faster. Most claims that fail on time were not too late in law; they were too late in practice, because by then the survey was closed, the ash was ploughed in and nobody could prove which field had been buried. Villages in coal belts such as Singrauli have seen this happen; our page on environmental cases in Singrauli covers the local picture.

Can the State Board be held responsible too?

The board is not liable to pay compensation the way the plant is, but its conduct is relevant and it can be made a respondent. If villagers complained about seepage or cracks before the breach and the board did not inspect, or if the plant's consent was renewed despite known problems with the pond, the tribunal can direct the board to explain, tighten monitoring and act against the plant.

Ask by RTI for the plant's consent conditions on ash pond management, the board's recent inspection reports, and any complaints it received about the pond. Ask the environment ministry's regional office for the plant's environmental clearance conditions and compliance reports on ash pond safety. Gaps in those records often explain how the breach was allowed to happen.

We operate ash ponds. What reduces our exposure?

Regular embankment safety inspections by qualified engineers, kept on record, with action taken on what they find. Maintained freeboard and working spillways and decant systems before every monsoon. Monitoring of seepage and piezometric levels. An emergency plan that the district administration knows about, including warning villages downstream. And a steady reduction of legacy ash under the utilisation notification, so that old ponds are emptied rather than raised again.

If a breach happens, report it at once, stop pumping into the affected pond, start containment and cooperate with the district administration on relief. Do not try to settle with villagers through full and final forms in the first days; tribunals view that poorly and it rarely holds. Our guide on defending an NGT case against your industry sets out how to respond once proceedings begin.
