Pipeline Approval Process in India: PESO Requirements, Documents & Steps

• The Pipeline Approval Process in India requires prior regulatory approval for the route, design, construction and working of petroleum pipelines under the applicable safety framework.
• For petroleum pipelines covered by the Petroleum Rules, 2002, PESO reviews technical drawings, route details, design calculations, testing arrangements and safety provisions before approval.
• Depending on the pipeline and product, additional requirements from PNGRB, environmental authorities, land-owning agencies and other competent authorities may also apply.

Introduction

Some months back, there was an industrial project which sought guidance from the compliance team while the pipeline engineering of the project was almost complete. The route had been identified, procurement process had begun and civil work was under way. The situation seemed simple in that the project engineers had assumed that regulatory approval could follow engineering.

However, when it comes to pipelines carrying petroleum, such an assumption could be quite costly.

Pipeline approval process does not only involve submission of drawings to the government agency in question. Such factors as route identification, right-of-way, design basis, petroleum type, pressure conditions, construction methods, testing processes, safety systems and operation processes should all tally.

According to the Petroleum Rules, 2002, no petroleum pipeline subject to the provisions of Part V shall be laid except upon prior written approval of the Chief Controller for route, design, construction and working. Moreover, the applicant must submit a project report covering drawings, calculations, codes, construction and testing information, route information, petroleum classification and maintenance arrangements.

Therefore, the best strategy is to deal with the approval issues during the design process and not after making construction decisions.

What Is the Pipeline Approval Process in India?

PESO ( Petroleum and Explosives Safety Organisation) is the regulation process that assesses whether the proposed pipeline route, design, method of construction and operation meet the necessary safety standards.

With regards to the petroleum pipelines covered under Petroleum Rules, 2002, the responsibility of PESO in respect of approval of design and route of pipelines transporting petroleum is described as a Head Office responsibility. This is evident from the present day SOP of PESO, where “Approval / alteration of design route of pipelines transporting petroleum” is one of the approvals undertaken at Head Office level.

This process typically entails:

1. Identifying the applicable regulatory framework.
2. Preparing the pipeline project report and engineering documents.
3. Finalising the proposed route and right-of-way information.
4. Preparing design calculations and technical drawings.
5. Submitting the application and prescribed documents.
6. Regulatory scrutiny and clarification, where required.
7. Construction and testing in accordance with approved arrangements.
8. Inspection and submission of as-built documentation.
9. Commissioning permission or applicable final regulatory clearance.

The exact requirements can change according to the product, pipeline type, location, route and applicable regulations.

Which Authority Approves Petroleum Pipelines in India?

The Petroleum and Explosives Safety Organisation or the PESO is the main safety organisation concerned with the approval of petroleum pipelines within its ambit, as per the Petroleum Rules, 2002.

The organisation claims that its role with respect to the Petroleum Rules includes transport of petroleum through pipeline and inspection of premises with regard to safety considerations.

However, an important aspect which is frequently ignored is that PESO approval and PNGRB approval are not essentially the same approval.

This is because PNGRB provides rules for authorisation and technical aspects relating to natural gas pipelines and petroleum and petroleum products pipelines. Currently, PNGRB has different regulations for authorisation, technical & safety standards and integrity management for petroleum product pipelines.

Thus, it is better to identify each type of approval at the beginning of any project.

---

When Is PESO Pipeline Approval Required?

Approval under PESO takes on special significance when the pipeline is being used to transport petroleum under the Petroleum Rules, 2002.

Section V of the Petroleum Rules relates specifically to transport through pipelines. Rule 87 covers the definition of scope, and Rule 89 requires written prior approval for the route, design, construction, and operation of the pipeline.

The project should first determine its applicability before freezing engineering.

This is especially true for:

• Cross-country petroleum pipelines
• Petroleum product transfer pipelines
• Pipelines connecting terminals
• Pipelines connecting storage facilities
• Industrial petroleum transfer systems where the applicable rules require approval
• Pipelines associated with petroleum installations
• Alterations to an already approved petroleum pipeline

The applicability should be determined from the actual product, pipeline configuration, location and regulatory framework rather than from the pipeline’s name alone.

Pipeline Approval Process: Step-by-Step

Step 1: Identify the Product and Regulatory Scope

The first question to ask is “What kind of substance will the pipeline contain?” rather than asking “What kind of application do we need to file?”

Petrol, diesel, crude oil, other petroleum products, and natural gas might each be subject to different laws. PNGRB laws might apply in the case of a natural gas pipeline, whereas laws related to Petroleum Rules and PESO might apply for a petroleum pipeline.

Step 2: Finalise the Pipeline Route

Route planning is one of the most sensitive parts of the Pipeline Approval Process.

It is incumbent upon the applicant to prove the alignment of the line, as well as ensure that the land, easements, and right-of-way necessary are available. Rule 88 under the Petroleum Rules stipulates that the pipeline and all associated facilities may not be constructed without acquiring the necessary land, easements and rights to enable construction and access to inspect, maintain, repair, replace, and patrol the facility.

This means that the route map must not be regarded as a mere map of location It must clearly indicate the alignment, crossing points, terminals, stations, valves, and other significant elements.

Step 3: Prepare the Comprehensive Project Report

The project report forms the technical backbone of the application.

PESO’s Petroleum Rules require a comprehensive project report accompanied by necessary drawings and calculations, including references to recognised codes followed for the design and construction. The report must also provide information about testing, route, petroleum class and provisions for maintenance and patrolling A strong project report should explain the engineering logic of the project rather than merely reproduce design data.

Step 4: Prepare Engineering Drawings and Calculations

The technical package may include:

• Pipeline alignment drawings
• Route maps
• Pipeline profile drawings
• Piping and instrumentation diagrams
• Station layouts
• Valve locations
• Crossing details
• Design calculations
• Wall thickness calculations
• Pressure calculations
• Corrosion protection methodology
• Safety system details
• Testing procedures
• Emergency arrangements

One practical issue seen in regulatory applications is inconsistency between different drawings. For example, the valve location shown on the route drawing may differ from the P&ID, or the pipeline length may differ between the project report and as-built documents.

Such inconsistencies are avoidable if the engineering document set is reviewed as one package.

Step 5: Select and Reference Applicable Codes

A pipeline is not approved merely because it has been designed by an experienced engineering team The project should clearly identify the recognised technical codes and standards followed for design, materials, fabrication, testing and operation.

For petroleum and petroleum product pipelines, PNGRB’s technical and safety regulations refer to requirements covering design, materials and equipment, piping components, fabrication, installation, testing, corrosion control, operation, maintenance and safety. The regulations also reference ASME B31.4 for relevant pipeline engineering requirements, subject to the modifications specified by the regulations.

The applicable code should be stated clearly in calculations and engineering documents.

Step 6: Submit the Application to the Competent Authority

After the technical package is completed, the application can be submitted through the applicable regulatory mechanism The submission should be internally checked before filing.

A useful internal review covers:

• Applicant details
• Pipeline ownership
• Product classification
• Route information
• Pipeline length
• Design pressure
• Diameter
• Material specification
• Engineering drawings
• Design calculations
• Testing methodology
• Safety arrangements
• Right-of-way documents
• Applicable permissions
• Project report

This stage is where a technical compliance review can prevent avoidable regulatory queries later.

Documents Required for Pipeline Approval

The exact document list depends on the project and approval stage. PESO’s published FAQ gives examples of documents required for commissioning permission, including as-built schematic drawings, as-built route maps, station layouts, P&IDs, profile maps, EIA and QRA documentation, HAZOP reports, right-of-way notifications, permissions from concerned authorities, crossing permissions, feasibility and thickness calculations, corrosion protection methodology, prescribed schedules, independent safety audit reports and inspection-related documents.

A project may therefore need documents such as:

Document	Purpose
Comprehensive Project Report	Explains the complete pipeline proposal
Route Map	Establishes alignment and important locations
Pipeline Design Drawings	Demonstrates engineering configuration
Design Calculations	Supports technical design decisions
P&ID	Shows process and control arrangement
Pipeline Profile	Shows elevation and route characteristics
Right-of-Way Documents	Demonstrates route access and legal rights
Crossing Permissions	Supports road, railway, waterway or other crossings
EIA Documentation	Addresses environmental considerations where applicable
QRA Report	Evaluates major risk scenarios
HAZOP Report	Reviews process hazards
Corrosion Protection Details	Demonstrates corrosion-control methodology
Testing Records	Establishes construction and integrity verification
Independent Safety Audit	Provides an independent compliance review
As-Built Drawings	Reflects the pipeline actually constructed

Not every project will require every document at the same stage.

---

What Happens During Technical Scrutiny?

Once submitted, the authority examines whether the proposal is technically and legally consistent with applicable requirements.

The review can cover:

• Pipeline route
• Design parameters
• Construction methodology
• Safety distances and arrangements
• Pressure conditions
• Material selection
• Valve and isolation arrangements
• Corrosion control
• Testing arrangements
• Emergency response provisions
• Maintenance and patrolling arrangements

If clarification is requested, the applicant needs to respond with technically consistent information.

A common mistake is to answer a regulatory query by changing one drawing without checking the rest of the project documents. That can create a second inconsistency.

The better approach is to identify the underlying issue, correct the source document and update all dependent drawings and calculations.

---

Is Inspection Required for Pipeline Approval?

Inspection requirements depend on the stage and nature of the project.

For commissioning-related requirements, PESO’s published FAQ lists a PESO inspection report among the documents associated with commissioning permission. It also refers to independent safety audit reports and compliance with recommendations Inspection is therefore not something that should be considered only after construction.

Before inspection, the project team should verify that:

• Approved design matches the constructed system.
• Safety systems are installed.
• Valves and fittings correspond with approved drawings.
• Testing records are available.
• As-built drawings are complete.
• Crossing permissions are documented.
• Route markers and other required arrangements are in place.
• Audit observations have been addressed.

---

Pipeline Commissioning: What Comes After Construction?

The approval process does not necessarily end when physical construction is completed.

PESO’s FAQ specifically identifies an extensive set of as-built and compliance documents for pipeline commissioning permission. These include as-built route and schematic drawings, station layouts, profile maps, environmental documentation, QRA and HAZOP reports, permissions, crossing records, thickness calculations, corrosion protection methodology, safety audit information and inspection documentation.

This distinction matters.

Approved design drawings describe what was authorised; as-built drawings demonstrate what was actually constructed If those two do not match, the project may face additional scrutiny before commissioning.

---

What Is the Fee for Pipeline Approval?

PESO’s published FAQ states a fee of ₹5,000 for a new pipeline and its route and ₹2,000 for amendment in the pipeline and its route. It also states that multiple cross-country pipelines laid on the same route can be included in a single approval application, although separate fees apply for each pipeline.

However, government fees are only one component of the project’s compliance cost.

Businesses should separately account for engineering documentation, surveys, testing, safety studies, environmental compliance, route permissions, inspection preparation and professional consultancy, where applicable.

A low application fee does not mean that the overall compliance exercise is inexpensive.

---

How Long Does the Pipeline Approval Process Take?

There is no universal approval timeline that can responsibly be promised for every pipeline project.

The duration depends on:

• Complexity of the route
• Pipeline length
• Product being transported
• Quality of technical documents
• Completeness of land and crossing permissions
• Regulatory queries
• Engineering changes
• Inspection requirements
• Environmental and other statutory permissions
• Applicant response time

For this reason, project planning should build regulatory approval into the engineering schedule from the beginning.

Waiting until construction is nearly complete can create a serious project bottleneck.

---

Common Reasons for Delay or Objection

Inconsistent Drawings

Different pipeline lengths, valve locations or station configurations across drawings can lead to questions.

Incomplete Route Documentation

Missing right-of-way or crossing information can weaken the application.

Poor Design Calculations

Calculations should clearly establish the basis of important engineering decisions.

Unclear Code References

The application should identify the recognised codes and standards used for the pipeline.

Construction Deviations

If the constructed pipeline differs materially from the approved design, additional review may become necessary.

Incomplete As-Built Records

Commissioning documentation needs to represent the actual installed pipeline.

Treating PESO as the Only Approval

Depending on the project, PNGRB and other statutory authorities may have separate jurisdiction.

---

PESO and PNGRB: What Is the Difference?

This is one of the most important distinctions for project owners.

PESO primarily addresses safety and regulatory approvals within its assigned petroleum and hazardous-material framework, while PNGRB has separate statutory functions relating to petroleum and natural gas pipelines, including authorisation and technical/safety regulations.

PNGRB currently publishes separate regulatory frameworks for natural gas pipelines and petroleum and petroleum products pipelines. Its petroleum-product pipeline framework includes authorisation regulations as well as technical and safety standards and integrity-management requirements.

Therefore, a pipeline project should begin with an approval matrix identifying every applicable authority.

Practical Advice for Businesses Planning a Pipeline

From a compliance perspective, the best time to review the Pipeline Approval Process is before the final route and engineering design are frozen.

A project owner should ask five questions at the beginning:

1. What product will the pipeline carry?
2. Which regulatory framework applies?
3. Which authorities need to approve or authorise the project?
4. What route and land permissions are required?
5. What documents will be needed at commissioning?

These questions appear basic, but they prevent a surprisingly large number of project-level problems.

Diligence Certification recommends treating regulatory approval as part of project engineering rather than as a separate administrative activity. This allows route, drawings, safety studies and documentation to be developed around the applicable requirements from the beginning.

How Diligence Certification Can Help

The Pipeline Approval Process involves engineering information as well as regulatory documentation. For many businesses, the difficulty is not preparing one particular document but making sure the entire submission tells one consistent technical story.

Diligence Certification can support businesses with:

• Regulatory applicability assessment
• PESO approval planning
• Document checklist preparation
• Technical document coordination
• Route and layout documentation review
• Application preparation
• Regulatory query coordination
• Inspection-readiness support
• Commissioning documentation
• Amendment and compliance support

The exact scope depends on the pipeline, product, route and regulatory requirements.

For a project involving petroleum or hazardous materials, early compliance planning is generally more economical than redesigning a pipeline after construction decisions have been made.

---

Conclusion

The Pipeline Approval Process should be treated as a project-engineering requirement, not as paperwork to be completed at the last stage.

For petroleum pipelines, the Petroleum Rules, 2002 establish the requirement for prior approval of the route and the design, construction and working of the pipeline. PESO’s current guidance also makes clear that technical documentation, inspection and commissioning records are important parts of the regulatory process.

At the same time, some projects may fall under additional PNGRB requirements or require permissions from environmental, land, road, railway or other authorities.

If your company is planning a new petroleum pipeline, modifying an existing route or preparing for commissioning, Diligence Certification can help map the applicable approvals, organise the documentation and coordinate the compliance process.
