Fly Ash Dumping: Rules for Power Plants and Complaints

Dumping fly ash on farmland, village commons, ponds, riverbanks or roadsides is not allowed. Under the fly ash utilisation notification of 31 December 2021, coal and lignite power plants must put their ash to approved uses such as bricks, cement, roads, embankments and the controlled filling of mine voids and low-lying land, and they pay environmental compensation when they fall short. Ash that is simply tipped on open land is pollution, not utilisation. You can complain to the State Pollution Control Board and the District Magistrate, and if they do not act, the NGT can order removal, restoration and compensation.

This guide deals with one problem: fly ash leaving a power plant and ending up where it should not. It explains what the rules allow, who is responsible when a contractor dumps ash, what a landowner who accepted ash should know, how to complain, and what plants should do to stay clear of these cases.

For the wider picture of living near a coal plant, start with our guide on thermal power and fly ash pollution. If ash has escaped in bulk from a breached embankment, read liability for an ash pond breach instead.

The essentials

Is it legal to dump fly ash on agricultural land or open plots?

No. Fly ash from a coal plant can be used only in the ways the notification and the guidelines under it allow. Dumping it loose on farmland, on village grazing land, beside a highway or into a pond is not one of those uses. It is disposal, and it is the very thing the utilisation rules were written to stop.

The confusion comes from the fact that some land filling is permitted. Ash can be used to reclaim low-lying areas and fill mine voids, under conditions. Contractors exploit that. They tell a farmer that his low field will be raised for free, or tell the panchayat that a pond will be made into a playground, and then bring hundreds of truckloads of ash with no approval, no soil cover and no protection for water. That is still illegal dumping.

The test is simple enough to apply on the ground. Is there an identified, approved project that the ash is going into, such as a road embankment under construction, a brick plant, or a filling site with permission? Or is ash just being unloaded where nobody will object? If it is the second, you have a valid complaint.

What does the 2021 fly ash notification require power plants to do?

The notification of 31 December 2021, issued under the Environment (Protection) Act, makes every coal and lignite thermal power plant responsible for utilising the fly ash it generates in an environmentally sound way, over a defined compliance cycle. It also requires the old ash accumulated in ash ponds, often called legacy ash, to be utilised progressively over a set period.

Plants that do not meet their utilisation obligation pay environmental compensation calculated on the unutilised quantity, and the money is meant to be used for safe disposal and ash management. The notification lists the approved uses and sets out obligations on construction agencies and other users to use ash-based products. Plants report their generation and utilisation figures to the regulators, and those figures can be compared with what is happening on the ground.

Two practical points matter for complaints. First, the duty is on the plant, so the plant cannot discharge it by handing ash to anyone who will cart it away. Second, the utilisation figures are only as good as the end uses behind them. Ash that was dumped on a field but recorded as used for land filling inflates the plant's figure, and exposing that is part of what a good complaint does.

Which uses of fly ash are allowed, and when do they become dumping?

This is a practical guide, not a list from the notification. Always check the current notification and guidelines for the exact conditions.

The contractor dumped the ash. Is the power plant still responsible?

Generally yes. The plant generates the ash and carries the utilisation duty, so boards and the NGT start with it. A plant that hands ash to a transporter without checking the end use, or pays for transport to a site it never verified, is treated as responsible for where the ash ends up. That is the polluter pays principle in its plainest form.

Others can be made liable too. The transport contractor who dumped it, the person who arranged the site, and the landowner who allowed it can all be respondents and can all be directed to pay or to remove the ash. In practice the tribunal often directs the plant to remove the ash within a deadline and leaves it to recover the cost from its contractor.

Plants sometimes argue that once ash leaves the gate, it is the buyer's problem. That argument has little force when the delivery challans carry the plant's name, the trucks run the same route every day, and the plant's utilisation report counts the ash as used. Tracing those links is usually what decides liability.

I allowed ash to be filled on my land. Am I in trouble?

Possibly, and it is better to deal with it early. Many farmers accept ash because a contractor promises to level a low field or pays a small sum per truck. If there was no approved project and no permission, the filling is unlawful and the landowner can be directed to stop it and, along with the plant and contractor, to restore the land. The land may also become harder to cultivate and harder to sell.

If you are in this position, stop further filling at once and keep every paper the contractor gave you: agreements, receipts, phone numbers, truck numbers. Those show that you were approached by a contractor working for a particular plant, which matters when liability is shared out. A landowner who comes forward and helps trace the ash is usually treated very differently from one who defends the dumping.

Anyone buying land near a power plant should check whether it was filled with ash, because restoration orders follow the land. Our guide on environmental due diligence before buying a site covers the checks worth doing.

How to complain about fly ash dumping

Fly ash dumping is easy to prove if you collect the right details while the trucks are still coming. Once the ash is spread and covered, it gets much harder.

One clear complaint from a farmer whose field is next to the dump is enough to start this. A panchayat resolution helps where the dumping is on common land.

What evidence works best in a fly ash dumping complaint?

Evidence that links the ash to a source. Photographs of a grey heap prove there is a grey heap, but a list of truck numbers seen over two weeks, matched with the plant's transport records, proves where it came from. The board can obtain those records from the plant; your job is to give it the vehicle numbers and the dates.

Next comes evidence of harm. Crops coated in ash, a pond turned grey, a hand pump giving cloudy water, dust in houses when the wind blows across the dump. Photographs with dates, revenue records of the land, and water test reports from an accredited laboratory all help. Our guide on using photos, lab reports and RTI replies as evidence explains how to make that material usable before the tribunal.

Finally, the paper trail. Copies of your complaints with diary numbers, and any reply or inspection report, show that the authorities knew and did nothing. That is what makes an NGT application against the regulators as well as the plant credible.

Fly ash is being dumped into a pond, river or drain. What then?

That is a more serious violation and should be reported as urgent. Ash in a water body breaks the Water Act as well as the fly ash rules, can smother aquatic life and turns water used by cattle and people turbid. If the water body is a village pond recorded in revenue records, filling it may also be an encroachment that the district administration must remove.

Ask the State Board to sample the water and the sediment, and ask the DM to stop the filling and restore the pond. Our guides on illegal filling of a lake or pond and restoring an encroached village pond cover the land side of the problem.

Where ash slurry is being discharged into a nala from the plant itself, through a pipeline or an overflowing pond, the complaint is about the plant's consent conditions and discharge standards, and the board should inspect the outfall. That is a different case from trucks dumping ash on land, and the complaint should say which it is.

Trucks are spilling fly ash on the road. Who acts?

Fly ash should move in covered or closed vehicles so that it does not blow off along the route. Uncovered trucks, overloaded tippers and ash spilling at every speed breaker are a common complaint in villages along plant routes. The State Board can direct the plant to enforce covered transport, and the traffic police and transport department can act against vehicles.

Record a few examples with vehicle numbers and dates, and send them to the board and the district administration together. The plant can be asked to impose conditions on its transporters and to clean the road. Residents along the route can also ask for regular water sprinkling, which joint committees have recommended where ash dust along roads was shown.

If ash is building up on the roadside because trucks unload it there for later pick-up, that is a dumping site in its own right and should be reported as one. Temporary heaps have a way of becoming permanent once a transporter loses a contract.

Ash is piling up at a brick plant or user unit near us. Is that covered?

Yes. A brick or block plant that uses fly ash is doing exactly what the notification encourages, but it still has to store the ash properly. Large open heaps of dry ash beside a kiln, with nothing to stop the wind lifting them, are a source of dust for neighbouring fields and houses, and the unit's consent from the State Board usually carries conditions on storage and dust control.

Complain about the storage, not the use. Ask the board to inspect and direct covered storage, wind barriers and water sprinkling. If the unit is taking far more ash than it can use and the surplus is being spread on nearby land, that is dumping again, and both the unit and the plant that supplied it can be asked to explain. Our guide on brick kiln pollution rules covers the wider rules for kilns.

What do the board and the NGT usually order in fly ash dumping cases?

The board can issue directions under section 5 of the EP Act or the relevant provisions of the Air and Water Acts, which can include stopping dumping, removing ash, and in serious cases restricting the plant's operations. It can also assess environmental compensation. In practice, boards often issue a show-cause notice to the plant first and inspect the site with revenue officials.

Before the NGT, the usual course is a joint committee report on the dumping sites, followed by directions to remove ash within a deadline, restore the land or pond, pay environmental compensation and put in place a system for tracking ash to its end use. Where farmers have lost crops or land, compensation for them can be ordered under section 15.

When Advocate B.K. Singh takes up a fly ash dumping complaint for villagers, he asks for removal and restoration first and compensation second, because a tribunal can supervise removal with a deadline, while compensation alone leaves the ash where it is. He also asks for the plant to disclose its end users, so that other dumping sites come to light.

We run a power plant. How do we avoid fly ash dumping cases?

Know where every truck goes. Contracts with transporters and users should name the end use and the site, require proof of delivery, and allow the plant to inspect. Spot checks on delivery sites cost far less than defending an NGT case about ash that appeared on fields with your challans attached.

Keep the utilisation figures honest. Reporting ash as utilised for land filling without an approved site behind it is the fastest way to turn a contractor's dumping into the plant's own violation. If utilisation is falling short, it is safer to report the shortfall and pay the compensation than to overstate the figures.

If a show-cause notice or an environmental compensation demand arrives, reply on facts and documents within time and ask for a hearing. Our page on environmental compensation demands explains how such amounts are examined.
