Illegal Change of Land Use Causing Pollution

When land is used for something its zoning does not allow, such as a dyeing unit in a residential colony, a ready mix concrete plant on farmland or a scrap yard in a village abadi, and that use causes pollution, you can attack it on two fronts. The land use violation goes to the development authority, municipal body or revenue authority, which can seal or stop the use. The pollution goes to the State Pollution Control Board, which can refuse or withdraw consent and order closure. The NGT can step in when the pollution raises a substantial environmental question and the authorities fail to act.

This guide is for residents and villagers living next to a unit that should not be where it is, and for owners of small units who have been told their premises are in a non-conforming area. It explains how land use permission (CLU) and pollution consent fit together, why one does not replace the other, and which authority to approach for what. For the general route to complain about pollution near your home, see our guide on pollution near your home.

Land use disputes about builders and lost green spaces are covered separately in our guide on construction on a green belt or park. This page is about polluting activities in the wrong place.

The essentials

A factory is running in our residential area and polluting. Is that illegal?

Usually, yes, on two counts. Master plans and zoning regulations divide land into residential, commercial, industrial, agricultural and other uses, and say which activities are permitted in each. Running a factory in a residential zone beyond the limited household activities a plan may allow is a violation of the plan and the building permission. If the factory pollutes, it also needs consent to establish and consent to operate from the State Pollution Control Board, and it may not have them, because boards generally will not grant consent to an industry located where the land use does not permit it.

The typical cases are familiar to anyone in urban India. Jeans washing and dyeing units in the lanes of urban villages, discharging coloured water into the drain. Plastic and e-waste processing in residential buildings, with burning at night. Metal workshops and electroplating units in houses. Car washing and service stations in residential plots. Dairies with dozens of cattle in colonies. On the edge of cities, ready mix plants, hot mix plants, brick kilns, crushers and godowns with DG sets on agricultural land without conversion.

Both violations are actionable, and they reinforce each other. A complaint that points out that the unit is in a residential zone, has no CLU and has no consent from the board is far harder to ignore than a complaint about smoke alone.

CLU and pollution consent: why one does not replace the other

A change of land use (CLU) is a planning permission. It is granted by the town and country planning department or development authority, and for agricultural land it is often combined with a conversion or declaration of non-agricultural use under the state's revenue law. It answers one question: may this land be used for this purpose? It says nothing about whether the activity meets emission and effluent standards.

Pollution consent under section 25 of the Water Act and section 21 of the Air Act is an environmental permission. It answers a different question: may this unit discharge effluent and emissions, on what conditions? Most boards ask applicants to show that the land use permits the activity before granting consent to establish, and many have siting norms for particular industries. Consent requirements depend on the CPCB category (red, orange, green or white), and some categories have been exempted or simplified by recent notifications, so check the current rule. Our page on industry categories explains them.

The practical point: a unit with a CLU but no consent is still operating illegally if it needs consent. A unit with a consent obtained by misstating its land use is exposed to having that consent revoked. And a unit with neither has no legal footing at all. When Advocate B.K. Singh is asked to look at a polluting unit in a residential area, he asks for the board's consent file before anything else, because the land use declaration the unit made on its application often settles the case.

Common land use and pollution violations, and who acts

How to complain about a polluting unit in the wrong zone

Run the land use and pollution complaints in parallel. Each authority will try to say the problem belongs to the other, so give each one its own complaint.

Does the pollution board check land use before giving consent?

In most states, yes. Consent applications ask for details of the site and its permitted land use, and boards generally refuse consent to establish where the land use does not permit the industry, or where state siting norms (distance from habitation, schools, water bodies) are not met. For some categories, such as stone crushers, hot mix plants and brick kilns, siting rules are set by the state, so check your state's current norms rather than relying on a figure from another state.

In Delhi, industrial activity in residential areas beyond what the master plan permits has long been a target of both sealing and refusal of consent, and the DPCC treats industries in non-conforming areas with suspicion. Elsewhere, enforcement is patchier, and many units in non-conforming areas simply never apply for consent. That is itself a violation if the unit falls in a category that needs consent, and the board can direct closure and stopping of electricity and water supply under section 33A of the Water Act and section 31A of the Air Act.

If the unit does hold a consent, read the application. A unit that declared its site as industrial when the zoning says residential has misstated a material fact, and that is a ground to ask the board to revoke the consent. Our page on consent to establish explains what boards ask for.

Industrial activity on agricultural land without conversion

On the edges of cities and along highways, agricultural land is often used for plants and yards without conversion or CLU. Each state's revenue law says how agricultural land may be put to non-agricultural use, usually through a declaration or conversion order by the revenue authority, and planning laws in controlled areas require a CLU from the town planning department. Without these, the use is unauthorised, and the revenue authority can take action under the state law.

These sites tend to be the worst polluters, because they are set up cheaply and temporarily: a hot mix plant for a road contract, a crusher for a season, a dumping yard for construction waste. Residents should complain to the tehsildar or SDM about the unauthorised use, to the State Board about the absence of consent, and to the DM about the nuisance. Village common land (gram sabha or shamlat land) used for such plants raises additional issues; see our guide on projects on common or ecological land.

Banquet halls, DG sets and late-night noise from commercial misuse

Not all land use problems involve factories. Banquet halls, party lawns, restaurants and gyms in residential areas cause a different kind of pollution: amplified music late at night, DG sets running for hours, parking spilling into lanes and kitchen smoke. Where the activity is not permitted in the zone, the municipal body or development authority can act on the misuse. The noise itself falls under the Noise Pollution (Regulation and Control) Rules 2000, which bar loudspeakers and public address systems between 10 pm and 6 am except in closed premises, and set a night limit of 45 dB(A) in residential areas.

For night noise, the police are the first call, and the DM or SDM is the authority under the Noise Rules. DG sets need to meet noise and emission norms, and large ones may need consent from the board. Our guide on DG set noise in a housing society or market covers that complaint, and the same land use argument strengthens it.

What each authority can actually do

Knowing the powers helps you ask for the right thing in each complaint.

Can the NGT act on an illegal change of land use?

The NGT acts on the pollution, not the zoning as such. If the unit discharges effluent, emits smoke, burns waste, runs DG sets or makes noise in breach of the Water Act, Air Act or the EP Act rules, that is a substantial environmental question within section 14, and the tribunal can direct the board to inspect, order closure, and assess environmental compensation on the polluter pays principle. It will often direct the land use authority to act too, because the two problems are linked.

A pure land use dispute, with no pollution, belongs to the planning authority and the High Court. A shop running in a residential house, without pollution, is a planning matter. A dyeing unit in the same house, draining dye into the colony sewer, is both. When residents frame the NGT application around the pollution and use the land use violation as supporting context, the tribunal engages. When they ask it to enforce zoning alone, it usually declines.

In practice, the NGT often forms a joint committee of the State Board, the DM and the municipal body to inspect and report. For clusters of units in non-conforming areas, such as an urban village full of washing units, it may direct a survey and action against all of them rather than the one named in the application. Our guide on construction in a no-development zone covers a related situation.

What to collect before you complain

Running a small unit in a non-conforming area? Your options

If your unit is in a residential or agricultural zone and you have received a notice from the board or the authority, the safest long-term course is relocation to a conforming industrial area. Some states and cities have, from time to time, notified schemes to redevelop or regularise clusters of industry in non-conforming areas. Check whether one applies to your location before spending money on a defence.

Do not apply for consent with a misleading land use declaration. It may get you a certificate, but it gives the board a clear ground to revoke it later, and it damages your position before the NGT. If a closure direction has been issued, our page on replying to a closure notice explains the options, including showing compliance and asking for time to relocate.

Mistakes people make in land use and pollution complaints

• Complaining to only one authority. The board says it is a zoning issue and the authority says it is a pollution issue. Send each one its own complaint.
• Not checking the consent file. The land use the unit declared to the board is often the strongest piece of evidence.
• Asking the NGT to enforce zoning alone. Frame the application around the pollution, with the zoning violation as support.
• Accepting a temporary closure. Units sealed by day often reopen at night. Keep a log and report each reopening.
• Relying on another state's siting norms. Distance rules for crushers, hot mix plants and kilns vary by state.
