CTO Renewal Checklist — Every Document You Need

This is the document list. If you want the process — timelines, the XGN steps, what happens at inspection — read the full CTO renewal guide instead. This page exists to be worked through, item by item, until every box is ticked.

Core documents

The non-negotiables. A renewal application without these is not an application.

• Existing consent order — every page, including the conditions annexure. Not the first page with the number on it.
• Previous CTE and every amendment issued since.
• Application form on XGN, filed against your existing unit profile — never a fresh registration.
• Consent fee challan for the correct capital investment slab, under both the Water Act and the Air Act.
• Authorisation letter or board resolution for whoever signs.
• Factory licence, current.
• Udyam registration, where applicable.

Land and premises

• GIDC allotment letter or lease deed, or clear title for private land.
• Site plan showing the ETP, storage areas, stacks and discharge points.
• NA permission, where the land was previously agricultural.
• Local body NOC — Panchayat, Nagarpalika or Corporation.
• CETP membership certificate, current, if your estate has a common plant. A lapsed membership holds the whole renewal hostage.

Monitoring and lab data

Twelve months of it. This is the section that most often has holes, because monitoring is easy to skip in a busy month and impossible to reconstruct afterwards.

• ETP inlet and outlet analysis — every month of the consent period, from a NABL-accredited lab.
• STP outlet analysis, where you have one.
• Stack emission reports for every source listed in your consent — boiler, thermic fluid heater, DG set, process stacks.
• Ambient air quality reports, typically required for Red-category units.
• Noise monitoring, where your consent specifies it.
• NABL accreditation certificate of the lab that did the work — check it was valid on the sampling date, not just today.
• Exceedance explanations. Where a parameter went over, the corrective action, dated. Reporting an exceedance with a fix is a compliance record; hiding it is a concealment finding.

Water and utilities

• Water source permission — GWSSB connection, borewell permission, or GIDC water supply agreement.
• Flow meter readings at ETP inlet and outlet, twelve months.
• Water consumption records reconciled against your consented water balance.
• Electricity bills, twelve months.

Hazardous and solid waste

• Hazardous waste authorisation, current.
• Form 3 register for the consent period.
• Form 10 manifests for every consignment moved off site.
• Form 4 annual returns for each year of the consent period.
• TSDF membership certificate or co-processing agreement, with the facility's authorisation number.
• Authorised recycler invoices, where waste went for recycling.
• Storage area photographs — impervious flooring, secondary containment, roofing, signage.

These four documents must tell the same story: Form 3, Form 10, Form 4, and Part D of your Form-V. Any two disagreeing is a finding, and reconciling them at 30 days is not possible.

Statutory returns

• Form-V for every year of the consent period. A gap in the series is one of the first things looked at — see the Form-V filing guide.
• Form 4 hazardous waste returns, all years.
• EC compliance reports, six-monthly, where you hold an EC.
• OCEMS uptime record, where OCEMS applies. Downtime is itself a compliance question.

Financial

• CA certificate of capital investment in plant and machinery — this sets your fee slab, so it must be current, not the 2019 figure.
• Audited financials, where asked.
• Bank guarantee, where one was a condition of the existing consent — with its status.

Compliance with existing conditions

The part that is not a document, and the part that decides the renewal. Your existing consent carries conditions. Renewal is partly an assessment of whether you honoured them.

• Go through the conditions annexure line by line.
• For each condition: is it done? Where is the evidence?
• Where a condition was not complied with — a flow meter never installed, a green belt never planted — decide now how you address it. Not at inspection.
• Prepare a condition-wise compliance statement. Nobody asks for this and it changes the tone of the entire scrutiny.

If anything changed

Renewing on stale unit data is one of the most common and most expensive mistakes. If any of these changed since the last consent, it is an amendment, not a renewal — and it needs disclosing here rather than being quietly carried over:

• Production capacity increased
• A product added or discontinued
• The manufacturing process changed
• A new emission source — boiler, DG set, thermic fluid heater
• The ETP scheme modified
• Water source or consumption materially changed
• A new hazardous waste stream appeared
• The occupier or the entity changed

A consent that does not describe your actual factory surfaces at the worst possible moment — during an inspection, in front of the officer, with the drawings in their hand.

Before you hit submit

• Every scan legible — an officer who can't read your ETP report raises a query rather than squinting.
• Files named clearly. `CTO_Renewal_ETP_Reports_Apr25-Mar26.pdf`, not `scan_0043.pdf`.
• Fee slab checked against the current schedule, not last cycle's.
• Unit profile on XGN matches reality.
• Filed against the existing unit, not a duplicate registration.
• Application number noted, and someone named as owner of the response to any query.
• Calendar reminder to check the portal weekly — queries do not phone you.

General information, not legal advice. Environmental regulation changes, and how a rule applies depends on your unit's category, location and consent conditions. Verify anything decision-critical against the current GPCB or CPCB position, or take professional advice.
