Hazardous waste authorisation in Tamil Nadu
Who this applies to
- The waste matches a process in Schedule I, or a constituent and concentration in Schedule II. Using a hazardous raw material is not, by itself, the test.
- You move waste across a State or across a border. Schedule III and the transboundary rules are a further test, and a domestic authorisation is not an import licence.
- E-waste, batteries, plastic packaging, tyres, biomedical waste, solid waste or construction waste may be a different rule. Do not fold them into this authorisation.
What the authorisation is
The Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016 cover generation, collection, storage, packaging, transport, use, treatment, processing, recycling, recovery, pre-processing, co-processing, utilisation, sale, transfer and disposal of scheduled hazardous and other waste. TNPCB grants the handling authorisation in Tamil Nadu. Import and export follow the allocation in the Rules, which can bring in MoEFCC, DGFT and Customs, and a DGFT permission answers a different question from a TNPCB authorisation.
Utilisation under rule 9 follows a Central Pollution Control Board standard operating procedure or another approved route, and the waste, its source, the process and the end use all have to match that route.
None of this is the same obligation as holding a hazardous chemical. A raw material is not a waste until the classification tests say it is.
Amendment rules made in 2025 add, from 1 April 2026, extended producer responsibility for scrap of non-ferrous metals: aluminium, copper, zinc and their alloys. If you make, sell or recycle products of those metals, check whether you are a producer, manufacturer or recycler under that new chapter of the Rules. It is a separate obligation from this authorisation.
What it costs to get wrong
Handling, storing, dumping, mixing, transporting or importing scheduled waste without the authorisation the Rules require can lead to action under the Environment (Protection) Act, an order to remediate, and action under your consent. This page does not state a fine. A lapsed consent to operate causes its own problem, because it can block both the authorisation and the electronic manifest.
The process
Classify the waste
Start by matching the process to Schedule I. Where that does not settle the classification, test constituents and concentration under Schedule II. A transboundary movement also needs the Schedule III category.
Apply in Form 1
TNPCB's guide requires Form 1 through OCMMS. Expect to provide a valid consent to operate, process and input-output data, storage arrangements and safeguards, an emergency response plan, and agreements with an authorised recycler, utiliser or treatment facility together with those counterparties' current approvals. A renewal also needs evidence of past compliance and the annual returns.
Under rule 6 the authorisation is valid for five years, and the renewal application goes in three months before it expires. TNPCB's summary of the Rules gives 120 days for a decision, but none of these periods helps an incomplete application, so check the Rules as amended on the date you file.
Receive Form 2, then move waste only as authorised
The authorisation issues in Form 2 after inspection and technical review. From then on, store waste in compatible, labelled containers within the quantity and time authorised, move it on the prescribed manifest only to a facility authorised for that stream, and keep Form 3 records that reconcile generation, dispatch and stock.
File Form 4, and amend before the waste changes
Form 4 is the annual return to TNPCB, due by 30 June for the preceding April to March (rule 20(2)). Its content differs for generators, for treatment-facility operators, and for recyclers, co-processors and users. Renewing your consent does not file Form 4.
Apply to amend before you add a waste category, raise the quantity, change storage, start utilisation, or change the disposal route.
Common failure points
- Calling a raw material a hazardous waste without a waste classification.
- Skipping Schedule II where Schedule I does not answer the question.
- Sending waste to a recycler authorised for a different stream.
- Importing other waste on a domestic TNPCB authorisation alone.
- Assuming every waste stream needs the same extended-producer-responsibility registration. EPR for a centrally portalised stream is its own filing.
