PESO Services for Dahej Industries
Dahej sites typically engage more than one rule set. The starting exercise is a map: which parts of the installation fall under which rules, and in what sequence the approvals need to arrive.
Petroleum Class A
Below 23°CHexane, benzene, toluene, naphtha. The Inflammable Substance Act, 1952 also brings acetone, ethyl alcohol and methyl alcohol under the Petroleum Rules.
Petroleum Class B
23°C to below 65°CDiesel (HSD), kerosene (SKO) and mineral turpentine. Usually held as utility or captive fuel stock rather than process input.
Petroleum Class C
65°C to below 93°CFurnace oil and light diesel oil — typically boiler and thermic fluid heater feedstock.
Alongside the Petroleum Rules, 2002, expect the SMPV(U) Rules, 2016 for pressure vessels, cryogenic tanks and bulk gas; the Gas Cylinder Rules, 2016 for cylinder storage and filling; and the Explosives Rules, 2008 where regulated explosive products are held. Electrical equipment in hazardous areas requires separate approval from the Chief Controller of Explosives, with zone classification governing permitted protection types.
For Gujarat applicants the PESO field office is the Vadodara Circle Office, headed by a Joint Chief Controller of Explosives.
Chemical & Petrochemical Licensing
Dahej’s industrial base spans petrochemicals, bulk chemicals, fertilisers, industrial gases and port-linked storage and handling. Two characteristics shape the licensing work.
Phased commissioning
Large sites come up in stages, and the licensing position changes with each phase. An approval obtained for phase one does not extend to phase two, and a drawing approved against the original layout will not describe the site after expansion. Planning the filings against the construction programme avoids a scramble at each commissioning date.
Interconnected installations
Tank farms connected to jetties, pipelines running between units, shared utilities and common corridors. Where an installation crosses a boundary or serves more than one operation, the licensing responsibility needs establishing early rather than assumed.
PESO’s published list of petroleum requiring a licence includes benzene, toluene, hexane, xylene, styrene and naphtha alongside motor spirit, high speed diesel, aviation turbine fuel, kerosene, light diesel oil and furnace oil — a range that covers most of what moves through this belt.
Hazardous Material Storage
Bulk storage assessment at Dahej scale covers the tankage, the transfer arrangements and the areas around them:
- Tank schedule. Capacity, construction, product class and test status for every tank on the plot.
- Bunding. Capacity relative to the tankage served, construction and drainage.
- Distances. To protected works, boundaries and between tank groups, driven by class and quantity.
- Transfer arrangements. Jetty connections, pipelines, loading and unloading bays and their area classification.
- Fire protection. Provisions matched to the product and quantity, including foam and water systems where required.
- Cryogenic and gas installations. Assessed under the SMPV(U) Rules with their own distance and fitting requirements.
On published quantity thresholds. Figures circulating on consultant pages are frequently out of date. Verify any threshold against the current rules for your class and storage mode before relying on it.
Documents & Application
PESO has moved to a paperless process, with applications routed through the National Single Window System. PESO’s published document on disposal timelines states that online applications are auto-inwarded four times a day and are to be processed within 21 days. Read that figure for what it is — a departmental processing timeline, not a promise of when your licence arrives. Elapsed time is governed almost entirely by how often the file goes back for clarification.
- Company constitution and incorporation documents, with signatory authorisation
- Land allotment, lease or occupancy documents, including SEZ or PCPIR documentation where applicable
- Site plan, key plan and layout drawings showing protected works and inter-unit distances
- Tank and vessel schedules with capacities, construction details and test certificates
- Vessel design calculations and material test certificates for SMPV installations
- Material list with classification, flash point and quantity
- Piping, transfer and jetty connection arrangements
- Electrical area classification and equipment approval status
- Safety and test certificates by a recognised competent person
- NOC from the District Authority for gas storage where required, and other applicable clearances
- Existing licences with approved drawings, for renewal or amendment
For SMPV installations, collect the vendor document pack at purchase. Chasing design calculations and material certificates from a fabricator after commissioning is the commonest reason a large-site application stalls.
Inspection & Safety
Where inspection applies, the installation is examined against the submitted drawings and schedules:
- A tank or vessel relocated during construction, never reflected in the approved drawing
- Stored quantities that have crept above the licensed figure
- Safety fittings replaced with a different make or specification
- Electrical equipment in a classified area whose approval status nobody has checked
- Distances on the drawing that do not survive a tape measure
- A site team that has never seen the drawing filed on their behalf
On phased sites there is an additional risk: an inspection covering the whole plot when only part of it was included in the approved drawing. Keeping the drawing current through each commissioning phase avoids that.
What a consultant can and cannot do. We prepare the file, brief your site team and draft replies to departmental observations. We have no role in how an inspection is conducted and no influence over its outcome. A One Consultant is a private consultancy — not a government body, and not appointed or authorised by one. Our practice does not extend to GPCB, CPCB or Drug Department matters.
Renewal & Amendments
Renewal timing varies by rule set, and misinformation circulates freely here. A documented example: under the SMPV(U) Rules, licences are granted or renewed for a maximum of three years ending 31st March, and the last date for receipt of a renewal application at the renewing office is 2nd March of the expiry year. Other rule sets carry their own validity periods and cut-off dates — check yours against your licence document rather than assuming the SMPV position applies.
For a Dahej site holding licences under several rule sets, the practical discipline is a single register carrying every licence, its rule set, its expiry, its renewal cut-off and its approved drawing reference. Tracking each licence within the department that operates the equipment is how cut-offs get missed.
Amendment applies when tankage or vessels are added or replaced, a different product enters an existing installation, transfer arrangements change, the layout is modified, or the company name, constitution or occupancy changes. Under the SMPV(U) Rules a licence cannot be transferred between companies.
Dahej Industrial Support
We work across the Dahej belt from our office at GIDC Char Rasta in Vapi, and across the wider Bharuch district including Ankleshwar, Panoli, Jhagadia, Valia and Sayakha. Many groups operate at more than one of these locations, and there is real value in having the licence register for all of them held in one place.
A One Consultant has worked on industrial licensing since 1999. Our client list includes Sun Pharma, Aarti Industries, Meghmani Organics, Polycab, Hindalco, Alok Industries, Zentiva and Jesons Industries.
We prepare and file. We do not approve, have no influence over departmental decisions, and do not handle GPCB, CPCB or Drug Department matters.
FAQs
Can one application cover a whole Dahej site?
No. Different rule sets require separate applications with their own forms, drawings and renewal dates. A site with solvent tankage, pressure vessels and cylinder storage needs three, even though they should be assessed together.
We are commissioning in phases. How should licensing be sequenced?
Plan the filings against the construction programme rather than reacting at each commissioning date. An approval obtained for one phase does not extend to the next, and the drawing needs updating as each phase completes.
Who is responsible for a shared pipeline or jetty connection?
That needs establishing early rather than assumed. Where an installation crosses a boundary or serves more than one operation, licensing responsibility should be documented before commissioning, not negotiated afterwards.
What documentation should we get from a vessel vendor?
Design drawings and calculations, manufacturer's certificate, material test certificates, hydrostatic and other test certificates, and safety fitting details. Make the pack a purchase order condition — obtaining it years later is considerably harder.
Do we need an NOC for bulk gas storage?
Under the SMPV(U) Rules, storage of compressed gases other than non-flammable, non-toxic gases requires a no-objection certificate from the District Authority. Its lead time sits outside the licensing process, so start it first.
How do we keep track of several licences?
A single register carrying every licence, its rule set, expiry, renewal cut-off and approved drawing reference. Tracking each licence within the department that operates the equipment is how cut-offs get missed.
Does an SEZ or PCPIR location change the PESO position?
The PESO framework applies on its own terms. Location documentation differs, and SEZ or PCPIR allotment papers form part of the application, but the licensing requirements follow the material, quantity and installation as elsewhere.
How long does an application take?
PESO's published timeline states that online applications through the National Single Window System are auto-inwarded four times a day and processed within 21 days. On large sites the practical schedule is usually set by collateral approvals and documentation readiness rather than by that timeline.
