Crusher, Sand & Stone Aggregate Rules in Nepal: Siting Standards & Chure Ban

Sand, gravel (locally called 'giti'), pebbles and crushed stone are the backbone of Nepal's construction boom, feeding roads, bridges, hydropower and housing. These aggregates are extracted from riverbeds and quarries and then processed at crusher plants that break boulders into usable sizes. Because the activity is lucrative and revenue-generating for local governments, it has expanded rapidly, often faster than regulators can control.

Unregulated riverbed mining has real costs: it lowers riverbeds, undermines bridge foundations and embankments, dries up springs, destroys aquatic habitat and worsens flooding. Nowhere are these risks sharper than in the Chure (Siwalik) hills, a young, loose, easily eroded range that recharges the aquifers of the densely populated Tarai plains below. This is why the rules combine two things: siting standards for where crusher plants may operate, and outright bans on extraction in sensitive zones.

The core rules are scattered across a government working standard, environmental law and a series of Supreme Court orders rather than a single statute. This page pulls those threads together for contractors, journalists, activists and local officials who need to know the current riverbed mining rules Nepal, the crusher distance from river Nepal requirements, and the status of the Chure ban.

The central framework is the 'Standard for Extraction, Sale and Management of Stone, Gravel and Sand' (Dhunga, Giti ra Balua Utkhanan, Bikri tatha Byabasthapan Sambandhi Mapdanda), issued by the Government of Nepal on 20 July 2020 (roughly Shrawan 2077 BS). It replaced earlier scattered directives and set minimum siting distances that crusher and stone-processing industries must maintain from sensitive features.

Under the 2020 standard, crusher industries were generally required to sit at least 500 metres away from rivers, streams, highways, motorable (concrete) bridges and historically or religiously important lakes and reservoirs. Larger buffers applied to more sensitive receptors: roughly two kilometres from dense human settlements, forests, protected areas, and archaeological, religious and cultural sites, as well as educational and health institutions. Extra buffers also applied to high-tension electricity transmission lines and to the international border.

Critically, the standard prohibited extraction and collection of stone, pebbles and sand from within forests, national parks and other protected areas, and from the Chure region. It also laid out how much material may be taken from a riverbed, requiring extraction to follow the natural flow and avoid deepening the bed, so that mining does not permanently damage the channel. These distances and bans are the reference point against which 'illegal' crusher operations are judged.

In May 2022 the government amended the 2020 standard, sharply reducing several buffer distances and, for the first time, setting separate rules for hill and Tarai districts. Media reporting summarised the changes as allowing crusher plants 'even closer to rivers, forests and villages.' In hill districts, the buffer from rivers and from the highway right-of-way was cut from 500 metres to 200 metres, and buffers from forests, bridges, settlements, schools, hospitals and heritage sites were cut from about two kilometres to 500 metres.

In the Tarai the river buffer stayed at 500 metres, but buffers from forests and bridges dropped to 500 metres and buffers from large settlements and cultural/educational/health sites dropped from two kilometres to about one kilometre. The amendment also relaxed other limits: reporting indicated the required distance from high-tension electricity lines was halved from 200 metres to 100 metres, and the buffer from the international border was reduced from two kilometres to one kilometre.

The amendment triggered immediate controversy from conservationists who argued it prioritised the crusher business over public safety and the environment. Advocates Padam Bahadur Shrestha, Raju Phuyal and Rakesh Kumar Shah filed a writ petition asking the Supreme Court to strike down the relaxed provisions, arguing they endangered rivers, settlements and heritage.

In June 2022 the Supreme Court issued a short-term interim (stay) order halting implementation of the amended, relaxed distances, following the writ petition against the changes. The order effectively kept the stricter 2020 buffers in force while the case proceeded, and it reinforced the message that siting distances cannot simply be diluted by administrative decision when public health and environmental rights are at stake.

This was not the court's first intervention in the sector. In June 2021 (18 June 2021), a Constitutional Bench issued an interim order stopping the government's budget policy for fiscal year 2021/22 that had proposed extracting and exporting sand, pebbles and stones to reduce the trade deficit. The bench cited Article 30 of the Constitution of Nepal (2015) the right to live in a clean and healthy environment and Article 51(g) on the sustainable use of natural resources with inter-generational balance.

Courts have also acted on specific rivers. In July 2021 the Supreme Court issued an interim order to protect the Kaligandaki River halting extraction of materials and removal of sacred shaligram stones which reporting says remained in effect for years before the underlying petition was decided. Together these rulings show a consistent judicial line: the constitutional right to a clean environment constrains how far the state and contractors can push extraction.

The Chure or Siwalik range is a young, geologically fragile chain of hills running east to west across southern Nepal, rising to around 1,200 metres and covering roughly 12–13 percent of the country's land area. It acts as a natural sponge, capturing monsoon runoff and recharging the groundwater that sustains the Tarai's farms and towns. Because the rock and soil are loose and easily eroded, over-extraction of boulders and sand from Chure rivers accelerates erosion, dries springs and pushes floods and sediment onto downstream communities.

Concern over 'excessive exploitation' and the export of construction materials to India led the government to move against Chure extraction and export around 2014 (2071 BS). The President Chure-Tarai Madhesh Conservation Development Board (PCTMCDB), a dedicated body based in Khumaltar, Lalitpur, coordinates conservation of the Chure across dozens of districts from Ilam in the east to Kanchanpur in the west. The 2020 working standard cemented the position by explicitly prohibiting extraction and collection of stone, gravel and sand from the Chure region.

The Chure extraction ban has remained politically contentious. Successive budgets and business lobbies have floated reopening quarrying and exporting Chure aggregates to cut the trade deficit, while conservationists, the courts and the constitution have pushed back. As of the 2020s, the standard's ban on extraction from the Chure, forests and protected areas remains the governing rule, even as enforcement on the ground is widely reported to be weak.

Extraction and crusher projects also fall under Nepal's environmental clearance regime, governed by the Environment Protection Act, 2019 (2076 BS) and the Environment Protection Rules, 2020 (2076 BS), which replaced the 1996 Act and 1997 Rules. Under this system, projects are screened by scale and sensitivity: larger or more sensitive projects require a full Environmental Impact Assessment (EIA), medium projects require an Initial Environmental Examination (IEE), and low-impact activities may need neither.

For riverbed and quarry extraction, the applicable thresholds and the requirement for an IEE or EIA are set out in the schedules of the Environment Protection Rules, 2020; the exact quantity or area thresholds should be checked against the current schedule and any location-specific rules, because projects in or near forests and protected areas face stricter scrutiny. Approval typically involves scoping, a report, public consultation and clearance from the relevant ministry or provincial authority before extraction can lawfully begin.

In practice, environmental approval, the siting standard and local revenue contracts (the 'thekka' awarded by local governments) are supposed to work together. Reporting over the years has repeatedly found gaps enthusiasm for revenue, weak monitoring and political protection allowing extraction that breaches distances, EIA conditions or the Chure/forest bans. Contractors should therefore treat both an environmental clearance and compliance with the siting standard as prerequisites, not formalities.

Even where the rules are clear, enforcement is uneven. Investigations have documented crusher plants operating within the banned buffers metres from rivers, highways and settlements as well as continued extraction from the Chure and from protected rivers despite court orders. Weak monitoring, overlapping jurisdiction between federal, provincial and local governments, and the sheer profitability of aggregates all contribute to persistent violations.

Some provinces have moved to issue their own crusher rules to tailor siting and licensing to local conditions, and a federal bill to consolidate the 'management and regulation of construction materials' has been discussed to bring coherence to a framework currently spread across a working standard, environmental law, mines and minerals rules and local governance provisions. Until such a law is enacted, the 2020 standard (with the stricter buffers reinstated by the courts), the EPA/EPR 2020, and Supreme Court orders remain the operative rules.

For anyone operating or scrutinising a crusher or riverbed extraction site, the practical checklist is: confirm the site sits outside forests, parks and the Chure; verify the required distances from rivers, highways, bridges, settlements, schools, transmission lines and the border; secure the correct IEE or EIA clearance; and hold a valid extraction contract from the local authority. Because specific figures have shifted with amendments and court rulings, always confirm the current standard and any interim orders before relying on a distance.
