Who Oversees Safety Inside Nepal's Hydropower Tunnels?

Ask a simple question about a hydropower tunnel in Nepal and the answer comes back in pieces. Who answers for what happens inside a headrace tunnel? Depending on which part you mean, it is the Department of Electricity Development, the Department of Labour and Occupational Safety, a rural municipality, or the environment ministry. None of them has anyone standing at the adit at shift change. That split is the story behind tunnel safety here, and it explains why a serious accident is so hard to pin on any one authority.

The paperwork that gets a tunnel started

A hydro project starts with a survey licence and later a generation licence from the Department of Electricity Development (DoED), the licensing body under the Ministry of Energy, Water Resources and Irrigation. The recommendation from the local body is part of that licence application file, not a separate permit issued at the end. A municipality or rural municipality has to recommend the applicant before DoED processes the file, but the licence itself does not come from the local body. Larger or more sensitive projects also need an environmental decision: an EIA cleared through the Ministry of Forests and Environment, smaller ones at provincial or local level. Our explainer on how hydropower licensing works in Nepal walks through the full sequence. The question here is narrower: which of those offices is responsible for the people underground?

DoED supervises the licence, not the workers

Everything DoED does concerns the project as a technical and commercial proposition. Are licence conditions being met? Is construction following the approved design? Are generation and commercial terms honoured? That is real oversight and it can be enforced. But it is not workplace inspection. Nobody at DoED is tasked with walking an underground face, checking ventilation or counting who is on shift. Expecting that office to behave like a safety inspectorate misunderstands what it was built to do.

The Department of Labour and Occupational Safety holds the actual power

Statutory workplace safety authority sits with the Department of Labour and Occupational Safety (DoLOS), under the Ministry of Labour, Employment and Social Security and working through district labour offices. An inspector can enter a construction workplace, tunnels included, examine records, speak to workers, issue notices and remediation orders, and pursue prosecution where the law has been broken. That mandate covers tunnels as much as factories.

The gap is operational, not legal. Project sites sit hours or days from the district headquarters, and inspectors are few and spread thin across the districts. Whether a headrace tunnel gets visited depends less on what the law allows and more on whether anyone can physically get there.

Local government, and the missing single owner

Municipalities and rural municipalities hold their own inspection and coordination powers over workplaces, sanitation and business activity inside their boundaries, and the ward office is often the closest government office to the adit. Add the district labour office, DoED and the environment ministry, and a project answers to several authorities at once.

We could not find a dedicated tunnel safety code in Nepal, or an inspectorate set up specifically for underground works. What does exist is a set of obligations that were plainly not written with a tunnel face in mind: occupational safety duties under the Labour Act 2074 (2017) and its Rules, management plans under environment law, and the technical conditions DoED attaches to a generation licence alongside the construction standards used on Nepal Electricity Authority projects. Each is real. None of them puts an inspector at the face continuously, which is where the risk concentrates.

The environmental plan is the closest thing to an audit trail

An approved IEE or EIA carries a management plan covering spoil disposal, slope stability, water management, dust control and community safety, monitored by the Ministry of Forests and Environment or the provincial environment division. It is not a tunnel safety document. It is a standing written commitment all the same, one a journalist or a family member can request, and it creates a paper record of what the project said it would do.

Who is responsible on site

The developer is the principal employer. Excavation is usually contracted out, sometimes through several layers, and employer-side duties such as insurance and accident provisions sit with whoever employs the worker of record. The Labour Act 2074 and the Labour Rules 2075 require a safety officer and a safety committee once a workplace crosses the workforce threshold set in those Rules. The number matters less than the principle: the duty attaches to the employer, not to the site in general.

Explosives run through a separate regime again. Storage and blasting permission comes through the District Administration Office and the Ministry of Home Affairs, not through DoED.

What actually goes wrong underground

The hazards in Nepal's headrace, tailrace and adit excavations are not exotic. Roof collapse and rockfall in weak or fractured rock. Poor ventilation letting gases and dust build up. Water inrush from an unexpected aquifer or a monsoon-fed fracture. Mishandled explosives. Long tunnels bored through steep, geologically young terrain on compressed schedules multiply all four.

After a death on site

Police respond to an unnatural death and open a report. The body goes for post-mortem at a district hospital. Police may pursue a negligence case. Under the Labour Act, the employer also has to notify the labour office of a workplace accident, and that office holds the file and can mediate between the family and the employer. These threads run in parallel rather than in sequence, which is part of why the process feels opaque from outside.

What a family can actually do

Start at the district labour office, which mediates. If mediation fails, the claim can go to the labour court. A civil damages claim against the contractor and the developer remains available separately. Workers registered as contributors to the contribution-based social security scheme can claim medical and accident benefits, including dependent-family protection. Registration is the weak link: a construction worker who was never enrolled falls back on the labour office, the courts and direct negotiation with the employer.

Who holds which record

DoED holds the project register. The Ministry of Forests and Environment or the provincial environment division holds the approval decision and the management plan. The district labour office holds inspection and incident files. The police hold their report, the district hospital holds the post-mortem, and the Social Security Fund holds the contribution record. Knowing which office holds what turns a closed door into a specific request.

None of this is a story about villains. Steep terrain, long headrace tunnels, compressed construction schedules, layered subcontracting and a largely unregistered daily-wage workforce combine to put tunnels at the sharp end of a hydro project. The rules that exist are split across three systems, so after an accident the practical questions are always the same: which office holds the record, and who is willing to act on it.

Safety, inspection and benefit rules are set in law and revised from time to time. Readers should confirm current terms with the issuing office.
