Environment Pollution Law Nepal 2026: EPA 2076 & EIA Guide

Nepal's environmental law is built around a single screening question — does this proposed activity need an environmental study before it can begin, and if so, at what tier? The Environment Protection Act 2076 (2019) sets out three tiers of pre-approval study (Brief Environmental Study, Initial Environmental Examination, full Environmental Impact Assessment), graduates the penalty for skipping the required tier, and gives the Department of Environment under the Ministry of Forests and Environment the power to enforce against violators. The framework sits under the Constitution Article 30 fundamental right to a clean and healthy environment and is supplemented by the Penal Code 2074 environmental-offence overlay where pollution amounts to a crime.

This guide covers the operational framework for industries, developers, NGO compliance officers and lawyers advising on environmental matters in Nepal. Which projects need which tier of study, what the penalty for skipping it actually costs, who regulates, what the EIA process looks like, and where the criminal-law overlay kicks in for serious pollution offences.

Our civil and corporate practice handles environmental compliance, EIA / IEE preparation review, defence in EPA 2076 enforcement actions, and public-interest litigation on pollution under the Constitution Article 30. The recurring pattern in defence work is the project that started construction without the required study because the developer assumed a lower-tier screening was sufficient. By the time the Department of Environment issues a notice the project is partially built and the penalty exposure is in the seven-figure range. Getting the screening tier right at the proposal stage is the highest-leverage piece of legal work in any project that affects land, air, water or biodiversity in Nepal.

What does the Environment Protection Act 2076 actually do?

The Environment Protection Act 2076 (2019) replaced the predecessor Act of 2053 and sits at the centre of Nepal's environmental regulatory framework. Its core mechanisms:

1. Project screening — every proposed activity that may affect the environment is classified into one of three tiers (Brief Study, IEE, or EIA) based on Schedule 1 of the Environment Protection Rules 2077
2. Pre-approval study — the proponent prepares the relevant tier of environmental study and submits it for review and approval before implementation
3. Approval and conditions — the Department of Environment (or relevant authority for IEE) reviews, may approve with conditions, may require modifications, or may reject
4. Implementation monitoring — the proponent implements the approved Environmental Management Plan, conducts ongoing monitoring, and submits periodic reports
5. Enforcement — the Department investigates violations, issues notices, levies fines, suspends or revokes approval where warranted
6. Pollution control — independent of project-screening, the Act prohibits pollution that significantly harms public life, health or the environment, and pollution that violates government-set standards

Industries operating without the required environmental study, projects breaching their approved Environmental Management Plan, and dischargers exceeding pollution standards all fall within the Act's enforcement perimeter.

The three tiers of environmental study

The Environment Protection Act 2076 read with the Environment Protection Rules 2077 classifies every proposal into one of three tiers based on Schedule 1 of the Rules. Schedule 1 lists project types and capacity thresholds that trigger each tier. The general principle:

The capacity thresholds and project-type lists in Schedule 1 are detailed and technical; the determination of which tier applies to a specific project requires reading the Schedule against the project's exact specifications. Hydropower projects, for instance, fall into different tiers based on capacity in megawatts; manufacturing projects fall into different tiers based on output, raw-material handling and effluent generation. Skipping the determination at the project-design stage is the most expensive procedural mistake in environmental compliance.

The EIA process — what happens at Tier 3?

For Tier 3 projects requiring a full Environmental Impact Assessment, the EPA 2076 read with the Environment Protection Rules 2077 prescribes a structured multi-stage process:

1. Screening — confirmation that the project requires an EIA based on Schedule 1
2. Scoping document — preparation and approval of the scope of the EIA, identifying the environmental issues to be assessed
3. EIA report preparation — detailed assessment of environmental impacts (air, water, soil, biodiversity, social), proposed mitigation measures, and the Environmental Management Plan
4. Public consultation — exposure of the EIA to public comment with formal hearings in the project-affected area
5. Technical review — review by the Department of Environment with expert consultation
6. Decision — approval (with or without conditions), modification requirement, or rejection by the relevant authority (Ministry / Cabinet for major EIAs)
7. Implementation and monitoring — proponent implements the Environmental Management Plan, conducts ongoing monitoring, submits periodic reports to the Department of Environment
8. Enforcement — Department investigates breaches, issues notices, levies fines or revokes approval where warranted

The IEE process at Tier 2 follows a similar but lighter structure with reduced public-consultation requirements and faster review timelines. The Brief Study at Tier 1 is the lightest track and typically does not require formal public hearings.

Constitutional right to a clean environment — Article 30

Article 30 of the Constitution of Nepal 2072 (2015) guarantees every citizen the right to live in a clean and healthy environment as a fundamental right. Crucially, Article 30 also gives the citizen the right to compensation from the polluter for damage caused. The combination is significant — the right is enforceable through writ jurisdiction at the Supreme Court (Article 133) or High Court (Article 144), and writ petitions on public-interest environmental issues have been a meaningful vehicle for environmental enforcement in Nepal.

Recent and well-known examples include writ litigation on Kathmandu Valley air pollution, illegal sand mining in the Terai rivers, and unauthorised construction in environmentally sensitive areas. The constitutional framework operates alongside the EPA 2076 administrative framework — proponents face both regulatory enforcement by the Department of Environment and potential public-interest litigation by affected citizens or NGOs.

Penal Code 2074 environmental offences

The Muluki Penal Code 2074 (2017) supplements the EPA 2076 with criminal-side environmental offences. Conduct that significantly harms public life, health or the environment can attract criminal liability in addition to the EPA 2076 administrative penalty. The Penal Code provisions cover:

• Polluting drinking water sources — public-health-focused offences against contamination of community water supply
• Air-pollution offences — discharges that significantly harm public health
• Noise pollution — nuisance-level noise affecting communities
• Hazardous-substance handling — improper handling, storage or disposal of toxic substances
• Damage to public natural resources — illegal extraction, encroachment on rivers, lakes, forests

The Penal Code overlay is particularly relevant in cases involving wilful pollution (a factory deliberately discharging untreated effluent, an operator dumping hazardous waste in a community area) where the conduct is more than an administrative non-compliance. Where the same conduct triggers both EPA 2076 and Penal Code charges, the prosecutor frames parallel cases and the court determines the applicable sentence on conviction.

The Department of Environment — practical compliance

The Department of Environment under the Ministry of Forests and Environment is the central regulator for the EPA 2076 framework. Its operational role:

• EIA review — technical review of EIA reports, recommendations to the approving authority (Ministry / Cabinet for major EIAs)
• IEE approval — direct approval authority for many IEE-tier projects
• Enforcement — investigation of complaints, issue of notices, levy of fines, suspension or revocation of approvals
• Pollution monitoring — air-quality, water-quality, noise monitoring against government-set standards
• Public engagement — receiving complaints from citizens and NGOs about non-compliant projects or pollution
• Coordination — works with provincial environment bodies and the Ministry on policy implementation

Practical advice for proponents: engage with the Department early in the project-design phase, get the screening tier determined correctly before any commitment to construction, and treat the Environmental Management Plan as a binding operational document not a check-the-box compliance artefact. Most enforcement cases involve gaps between the approved Plan and actual operations.

Public-interest litigation under Article 30

The combination of Constitution Article 30 with the writ jurisdiction of the Supreme Court (Article 133) and the High Court (Article 144) gives Nepali citizens and civil-society organisations an enforcement route independent of the Department of Environment. Affected citizens or NGOs can file a writ petition seeking:

• Mandamus — directing the Department of Environment to act on a non-compliant project
• Prohibition — restraining further work on a project pending environmental compliance
• Compensation — under the Article 30(2) right to compensation from the polluter for damage caused
• Direction to formulate or amend rules — particularly for systemic regulatory gaps

Public-interest writ litigation has been central in several high-profile environmental matters in Nepal. The procedural framework for writs is covered in our writ procedure guide.
