A manufacturing plant may spend several crores on machinery, electrical systems and production infrastructure, but one incorrectly located diesel tank can delay the entire commissioning schedule.
This often happens when a business installs a petroleum storage tank before checking the applicable petroleum class, safety distance, District Authority NOC and PESO layout approval requirements.
For example, a company planning to store 60 KL of high-speed diesel cannot treat the tank as ordinary utility equipment. The installation may require prior layout approval under Rule 131, a No Objection Certificate under Rule 144, tank testing, a safety certificate and a valid PESO License for Petroleum Storage in India before petroleum is stored.
The Petroleum Rules classify petroleum according to flash point, storage capacity and storage method. Even a Class C petroleum installation below 45,000 litres may require a one-time approval or prior report to PESO.
Petroleum storage compliance should therefore begin before finalising the plant layout, ordering the tank or starting civil construction.
A PESO petroleum storage licence is a statutory safety approval for storing regulated petroleum products in tanks, containers, service stations, industrial installations and other approved premises.
PESO stands for the Petroleum and Explosives Safety Organisation. It functions under the Department for Promotion of Industry and Internal Trade and administers important safety laws covering petroleum, compressed gases, gas cylinders and explosives.
For petroleum storage, the principal legal framework includes:
The licence does not only mention the company name. It is connected to a specific site, approved drawing, petroleum class, storage capacity, tank arrangement and operating method.
A licence granted for one 50 KL diesel tank cannot automatically be used for an additional 30 KL tank. Similarly, a licence for storing one petroleum class should not be used for another petroleum product without checking its flash point and obtaining the required amendment.
The following figures are important for planning a petroleum storage project:
These numbers should be treated as regulatory planning points. The final requirement depends on the actual petroleum product, installation, tank design and licence form.
Petroleum storage creates a combination of fire, explosion, leakage, vapour, static-electricity and occupational-safety risks.
A minor leak from a tank, flange, pump or unloading hose can contaminate soil and drains. Vapour accumulation near an ignition source can cause a serious fire. An unsafe tanker movement route can also create risks for workers and surrounding properties.
PESO approval helps ensure that the installation has been planned with appropriate safety controls before petroleum is stored.
The approval process examines matters such as:
Petroleum storage compliance is also commercially important. Fuel suppliers, insurers, lenders, auditors and industrial customers may ask for proof that the storage installation is legally approved.
Petroleum is classified according to its flash point. Flash point is the lowest temperature at which the product gives off enough vapour to ignite under specified test conditions.
The product name alone should not be used for classification. The applicant should check the Safety Data Sheet, certificate of analysis or recognised laboratory test report.
| Petroleum class | Flash-point range | General risk level |
|---|---|---|
| Class A | Below 23°C | Highly flammable |
| Class B | 23°C or above but below 65°C | Flammable |
| Class C | 65°C or above but below 93°C | Combustible petroleum |
| Outside A, B and C | 93°C or above | Generally outside this three-class licensing structure |
Petrol generally falls within Class A because of its low flash point. Many industrial fuels and solvents may fall under Class B. Certain heavier petroleum products may fall under Class C.
However, the classification must always be confirmed from the actual product data.
Before preparing the application, the business should collect:
Licence applicability depends on the petroleum class, quantity and manner of storage.
The Petroleum Rules contain limited exemptions for small quantities. These exemptions should not be treated as permission to ignore fire safety, pollution-control requirements or local approvals.
| Storage arrangement | General licence position |
|---|---|
| Class A up to 30 litres and not intended for sale | Petroleum storage licence may not be required, subject to conditions |
| Class B up to 2,500 litres and stored otherwise than in bulk | Petroleum storage licence may not be required |
| Class C up to 45,000 litres in bulk | Full storage licence may not be required, but PESO prior report or one-time approval is relevant |
| Class A above 30 litres and up to 300 litres | District Authority licence in Form XII may apply |
| Class B above 2,500 litres and up to 25,000 litres in non-bulk storage | District Authority licence in Form XIII may apply |
| Industrial tank installation | Form XV generally applies |
| Service-station tanks connected to dispensing pumps | Form XIV generally applies |
| Larger non-bulk petroleum storage | Form XVI may apply |
| Mobile on-site refuelling | Form XIX may apply |
A factory should not divide one planned storage requirement into several smaller tanks merely to claim an exemption. PESO may evaluate the total installation, operational arrangement and actual purpose of the storage.
The following factors must be examined together:
Choosing the correct form is one of the most important stages of the application.
Many applications are delayed because the applicant files a Form XIV case for an industrial installation that should have been assessed under Form XV.
| Licence form | Main purpose |
|---|---|
| Form XII | Import and storage of limited quantities of Class A petroleum |
| Form XIII | Import and non-bulk storage of limited quantities of Class B petroleum |
| Form XIV | Storage in tanks connected to pump equipment used for fuelling motor vehicles |
| Form XV | Import and storage of petroleum in an installation |
| Form XVI | Storage of petroleum otherwise than in bulk above specified quantities |
| Form XVIII | Decanting kerosene from a mechanically propelled vehicle into containers |
| Form XIX | Mobile refuelling of aircraft, heavy machinery, vehicles or stationary equipment |
Form XIV is commonly associated with retail outlets and service-station type arrangements.
Form XV is commonly relevant where an industrial plant, depot or commercial facility stores petroleum in fixed tanks as part of an installation.
Before selecting the licence form, the applicant should answer:
| Regulation or rule | Main requirement | Numerical timeline | Key risk |
|---|---|---|---|
| Petroleum Act, 1934 | Lawful storage and compliance with licence conditions | Before regulated storage begins | Prosecution and confiscation |
| Petroleum Rules, 2002 | Design, construction, licensing and operation | Continuous compliance | Licence refusal or cancellation |
| Rule 131 | Prior approval of specifications and plans | Before construction | Tank relocation or civil rework |
| Rule 144 | NOC from District Authority | Decision within 3 months | PESO application delay |
| Rule 126 | Tank testing certificate | Before licence grant where applicable | Tank cannot be commissioned |
| Rule 130 | Safety certificate | Before grant or amendment | Technical rejection |
| Rule 146 | Approval before alteration | Before changes are made | Existing licence becomes inadequate |
| Rule 148 | Licence renewal | Apply at least 30 days before expiry | Late fee or fresh application |
| Rule 152 | Suspension or cancellation | On contravention | Storage operation may stop |
| Petroleum Amendment Rules, 2024 | Updated fees, NOC and inspection provisions | Effective from 4 March 2024 | Use of outdated procedures |
The applicant should first obtain the Safety Data Sheet and verify the flash point.
This step determines whether the product falls under Class A, Class B or Class C. It also affects the safety distances, firefighting system, electrical classification and licence fee calculation.
Incorrect product classification can result in a discrepancy letter or rejection.
The classification file should contain:
The company should prepare a complete storage schedule rather than mentioning only the total fuel requirement.
For example, a total storage capacity of 60 KL may consist of:
Each arrangement can affect the layout, interdistance, dyke design and operational risk.
The storage schedule should mention:
The proposed tank area should be reviewed before civil work begins.
A site may appear suitable because open land is available, but it may still fail due to proximity to a factory building, electrical room, road, neighbouring property, school, hospital or other protected work.
The feasibility study should examine at least:
Rule 131 requires prior approval of the specifications and plans for applicable petroleum storage premises.
The drawing should be prepared to scale and should clearly show the proposed petroleum facilities.
Construction should not begin merely on the basis of an internal engineering drawing.
A Rule 131 plan generally includes:
Most new petroleum storage installations requiring a PESO licence also need an NOC from the District Authority.
The District Authority may consult departments dealing with land records, police, traffic, fire safety, town planning and road access.
Under Rule 144, the NOC application should be decided as expeditiously as possible and no later than 3 months after receipt.
The NOC process may examine:
A mismatch between the PESO plan and the District Authority plan can cause avoidable delays.
The application is generally filed through the National Single Window System and the linked PESO module.
The applicant must select the correct approval, transaction and licence form.
A complete application should include the required forms, plans, NOC, land documents and fee payment.
The online filing normally covers:
After receiving plan approval, the company may proceed with construction in accordance with the sanctioned drawing.
The civil contractor and equipment supplier should receive a controlled copy of the approved layout.
Unapproved deviations should not be made to save space or reduce construction cost.
Common deviations include:
Even a technically safe change may require prior approval and licence amendment.
The tank must be tested by a recognised competent person or approved third-party inspection agency, where applicable.
The testing process helps verify tank integrity, installation quality and compliance with approved specifications.
Rule 126 and Rule 130 documents may be required before the final licence is granted.
The certification file can include:
After reviewing the final documents, PESO may grant the licence with an approved drawing attached.
The licence should be kept available at the premises.
The company must operate only within the approved:
The exact documents depend on the licence form and project configuration.
For an industrial Form XV installation, the principal documents normally include:
Depending on the industry, the applicant may also require:
PESO approval and SPCB approval are separate.
PESO primarily examines petroleum and fire-explosion safety. The SPCB examines air pollution, water pollution, waste, effluent and environmental controls.
The licence fee for Forms XIV, XV and XVI is linked to the licensed capacity and petroleum class.
For each petroleum class, the fee is generally calculated as:
Suppose a company proposes to store 80 KL of one petroleum class.
The indicative calculation would be:
Where 2 different petroleum classes are stored, the fee may be calculated separately for each class according to the schedule.
The Petroleum Amendment Rules, 2024 also prescribe separate fees for certain transactions.
| Transaction | Government fee |
|---|---|
| Prior approval of specifications and plans under Rule 131 | ₹2,000 |
| Prior report for Class C storage under Rule 140 | ₹2,000 |
| Approval for addition or alteration | ₹2,000 |
| Licence amendment | ₹2,000 |
| Licence transfer | ₹2,000 |
| Import permission for an ISO tank container | ₹5,000 |
Government fees do not include expenses for:
There is no single guaranteed timeline for every petroleum storage project.
PESO issued an internal direction for applications to be processed within a 21-day target, subject to complete documentation and compliance.
However, the total project timeline can be longer because the application involves several stages.
| Activity | Indicative duration |
|---|---|
| Product classification | 2 to 5 working days |
| Site-feasibility review | 5 to 15 working days |
| Technical drawing preparation | 7 to 20 working days |
| Rule 144 NOC | Up to 3 months |
| PESO scrutiny of a complete file | Target of 21 days |
| Construction and tank installation | Project-specific |
| Testing and safety certification | 5 to 15 working days |
| Final licence grant | Case-specific |
A properly planned project may complete the documentation and licensing sequence smoothly.
A project with unsuitable land, incorrect drawings or an already installed tank may take several additional months.
There is no universal 3-metre, 6-metre or 9-metre rule that applies to every petroleum tank.
The required distance depends on:
For certain larger installations, the interdistance between Class A or Class B tanks and a Class C tank should not be less than 6 metres.
However, this figure should not be copied into every project without checking the applicable table and approved licence form.
The layout design should separately assess:
Petroleum storage licences generally operate on a calendar-year basis.
Eligible licences may be renewed for a period of up to 3 calendar years where there is no violation of the Petroleum Act, Petroleum Rules or licence conditions.
The renewal application should normally reach the licensing authority at least 30 days before the licence expires.
Where the renewal application is submitted late, additional fees may apply.
If the application reaches the authority more than 30 days after expiry, the case may not qualify for ordinary renewal and a fresh licence application may become necessary.
The compliance team should track:
A valid licence does not permit unlimited changes to the installation.
Rule 146 requires prior approval before making alterations to licensed premises.
A licence amendment may be required when the company proposes to:
The company should compare the physical site with the approved licence drawing at least once every year.
A tank installation that no longer matches the approved drawing can face suspension, cancellation or operating restrictions.
The following composite case study reflects a common compliance problem faced by industrial projects.
A mid-sized food-packaging company was setting up a new manufacturing unit in Gujarat. The plant had a connected electrical load of nearly 2 MW and required 3 large diesel generators for emergency backup.
The engineering team planned one 60 KL high-speed diesel tank. The plant head believed the diesel tank was a minor utility item and approved the purchase before consulting a petroleum-safety professional.
The supplier fabricated the tank, and the civil contractor completed the foundation near the utility block.
By the time the compliance team started the PESO application, the company had already spent approximately ₹22 lakh on the tank, foundation, piping, pumps and unloading area.
During the technical review, 4 major issues were identified.
First, the product SDS indicated that the diesel had to be assessed within the applicable petroleum class based on its flash point. The original project file did not contain any formal classification record.
Second, the 60 KL industrial storage arrangement required a proper Form XV evaluation. The team had initially started preparing documents similar to a service-station Form XIV application.
Third, the tank was positioned too close to an electrical room. The tanker unloading route also blocked access to one of the emergency exits.
Fourth, Rule 131 plan approval and the Rule 144 NOC had not been obtained before construction.
The plant head, finance team and contractor then had to work together to correct the project.
The company shifted the tank foundation by approximately 11 metres, redesigned the unloading bay, modified the pipeline route and added a more suitable emergency-access path.
The corrective civil and mechanical work cost approximately ₹6.5 lakh. The project also lost nearly 7 weeks because the generator system could not be commissioned with permanent fuel storage.
The compliance file was subsequently completed with:
The company ultimately received the required approval, but the plant head later acknowledged that a pre-construction compliance review costing a small fraction of the corrective expense could have prevented the delay.
The most important lessons from the case were:
Operating without the required licence can expose a business to more than a small statutory fine.
The licensing authority may suspend or cancel the licence where the licensee violates the Petroleum Act, Petroleum Rules or licence conditions.
The Petroleum Act also contains provisions for prosecution and confiscation of petroleum and receptacles in specified cases.
Commercial consequences may include:
The Petroleum Act contains legacy monetary penalties that may appear comparatively small. However, the actual business loss from shutdown, accident, reconstruction and delayed production can reach several lakhs or crores.
Environmental penalties may also arise separately where petroleum leakage, contaminated soil, hazardous waste or water pollution is involved.
Under the amended Environment Protection Act framework, general penalties may range from ₹10,000 to ₹15 lakh in applicable cases, with additional daily penalties for continuing contraventions.
Company-related environmental penalties may range from ₹1 lakh to ₹15 lakh, depending on the applicable provision.
These environmental penalties should not be confused with the primary PESO licensing provisions. A single incident may create liability under multiple laws.
A petroleum storage consultant should become involved before the tank is purchased or the plant layout is frozen.
The consultant should not only upload an application. The role should include technical planning, document review and coordination between different approvals.
Professional support may include:
Early professional review can prevent errors that are difficult to correct after civil construction.
A PESO License for Petroleum Storage in India is not a simple registration certificate. It is a technical approval connected to the petroleum class, storage quantity, land, tank design, safety distance, District Authority NOC and sanctioned layout.
Important numerical limits such as 30 litres for limited Class A exemption, 2,500 litres for certain Class B non-bulk storage and 45,000 litres for Class C storage should be interpreted carefully.
Class C storage below 45 KL may not require a full storage licence, but the applicable PESO prior-report or one-time approval should still be completed.
Industrial projects should begin the licensing process before tank procurement. Rule 131 approval should be obtained before construction, while the Rule 144 NOC process may take up to 3 months.
The cost of early compliance is normally much lower than the cost of shifting a tank, modifying a dyke, changing the tanker route or delaying factory commissioning.

Licence applicability depends on the diesel flash point, quantity and storage method. Industrial bulk storage commonly requires a Form XV assessment and PESO approval.
A full storage licence may not be required for Class C petroleum up to 45,000 litres. However, the prescribed one-time approval or prior-report process with PESO remains relevant.
Form XV is used for importing and storing petroleum in an installation. It is commonly applicable to industrial petroleum tanks, depots and fixed storage facilities.
PESO has a 21-day internal scrutiny target for complete applications. However, the Rule 144 District Authority NOC may take up to 3 months, and the total timeline depends on construction, testing and document completeness.
