PESO Approval Documents
Checklist (Excel)

PESO (Petroleum and Explosives Safety Organisation) is the Indian regulatory authority that licenses storage, handling, transport, and import of petroleum, compressed gases, explosives, and pressure vessels. PESO operates under the Department for Promotion of Industry and Internal Trade and administers the Petroleum Act 1934, the Petroleum Rules 2002, the Gas Cylinder Rules 2016, the Static and Mobile Pressure Vessels (SMPV) Unfired Rules 2016, and the Explosives Act 1884. You need a PESO licence to store Class A, Class B, or Class C petroleum above threshold quantities, to operate LPG storage, to manufacture or fill gas cylinders, and to operate cross-country petroleum pipelines.

A PESO approval dossier typically requires the application form in the prescribed format, site plan and layout drawing showing inter-distances, plot plan with hazardous area classification, vessel datasheets and manufacturer certificates, design calculations certified by a chartered engineer, fire fighting layout and water demand calculation, electrical area classification drawing, no-objection certificate from the District Magistrate, no-objection certificate from the State Fire Authority, environmental clearance where applicable, insurance documents, and the licence fee challan. The exact list varies by licence type (Petroleum Class A versus SMPV versus Gas Cylinder). See the PESO compliance workflow.

Pathnovo, an engineering document intelligence platform, auto-prepares a PESO approval dossier by ingesting the project document set (plot plan, P&IDs, equipment list, datasheets, hazardous area classification, fire layout, design calculations) and mapping every PESO required document to the source it must be generated from. Missing or inconsistent inputs are flagged with the PESO rule reference (Petroleum Rules 2002, SMPV Rules 2016, or Gas Cylinder Rules 2016) so the applicant can correct upstream before formal submission. Typical dossier preparation drops from 8 weeks manual to 2 weeks auto-prepared. See the PESO standard reference.

PESO (Petroleum and Explosives Safety Organisation) is the umbrella regulatory body. CCOE (Chief Controller of Explosives) is the senior statutory office within PESO that issues operating licences for petroleum storage, tank farms, and explosive installations. In practice, the CCOE signs the final operating licence for major Class A and Class B petroleum installations, while PESO sub-offices in Nagpur, Faridabad, Kolkata, Chennai, and Mumbai handle regional approvals. A typical Class A petroleum installation goes through PESO regional review followed by CCOE final licensing. See the CCOE compliance workflow and the CCOE approval documents checklist.

OISD 118 layout compliance is a prerequisite for PESO licensing. The PESO application requires a layout drawing showing Class A, Class B, and Class C inter-distances per the Petroleum Rules 2002, and the OISD 118 Chapter 3 inter-distance table is the de-facto basis used by PESO inspectors during pre-licence inspection. A site that fails OISD 118 Chapter 3 inter-distance will not get a PESO licence. The checklist cross-references OISD 118 compliance status per equipment, so layout gaps are caught before PESO submission. See the OISD 118 compliance checklist.

PESO approval timing depends on licence type and PESO sub-office workload. A typical Class A petroleum storage licence under the Petroleum Rules 2002 takes 4 to 9 months from application to operating licence, with site inspection between months 2 and 5. SMPV licences for static pressure vessels typically take 2 to 4 months. Licence validity is 3 years for most petroleum and SMPV licences, with renewal application required at least 90 days before expiry. The checklist tracks both application status and renewal due date so no licence lapses.

For major Class A and Class B petroleum installations (refineries, large tank farms, LPG terminals), the PESO regional approval feeds directly into the CCOE operating licence application. Most of the documents in the PESO dossier (site plan, layout drawing, vessel datasheets, manufacturer certificates, fire layout, hazardous area classification, NOCs) are re-used in the CCOE application with the addition of CCOE-specific items (storage shed approval, operating procedure manual, emergency response plan). The checklist cross-references CCOE application status per document, so the PESO and CCOE dossiers stay aligned.
