Pollution Consent (CTE/CTO) for a Factory in Gujarat: GPCB Process and Documents

A factory in Gujarat needs two consents from the Gujarat Pollution Control Board (GPCB): Consent to Establish (CTE) before you build, and a Consolidated Consent and Authorisation (CC&A) before production starts. They come under the Water Act and Air Act. Red, orange and green units apply; a listed set of white-category sectors is exempt. Validity and fees are set by the Board, so confirm them for your category.

Which consent do you need, and at what stage?

Section 25 of the Water Act and section 21 of the Air Act require prior consent to set up and then to operate an industrial plant. In Gujarat GPCB combines the two Acts, and the hazardous-waste authorisation, into one document, the CC&A. The sequence is fixed:

• Before construction: CTE. Where a project needs environmental clearance under the EIA Notification 2006, GPCB lists the clearance and the EIA report among the documents to file with the application.
• After construction, before production: CC&A, once the effluent treatment, air pollution control and stack arrangements in the CTE conditions are in place and the Board has inspected.
• On expansion or change of process: an amendment. A new line, a boiler or a DG set that changes the pollution load is not covered by the earlier consent.

White-category sectors need neither. The Central Government exempted 86 white-category sectors from consent under the Water Act (G.S.R. 762(E), 17 October 2025) and under the Air Act (G.S.R. 761(E) of the same date). The list includes assembly of air coolers or conditioners with repair and servicing, completely dry electrical and electronic assembly, and engineering and fabrication units with a dry process and no heat treatment, metal surface finishing or painting. If your plant adds a paint shop or a heat-treatment furnace, it leaves the white list. GPCB publishes an updated list of white-category sectors on its site; check your activity against it.

How does the GPCB process run?

A GPCB process-flow sheet for CTE directs applicants to the Single Window System and the Board's website carries an online consent login. The same sheet, which is undated and from the ease-of-doing-business exercise, quotes 120 working days for the whole process excluding the applicant's own delays. Treat that as historic and ask the regional office for the current time limit.

Which documents does GPCB ask for?

A GPCB circular dated 5 June 2025 revised the list of documents that go with consent applications to match the central ease-of-doing-business changes. It covers fresh CTE and CC&A applications, and says that for renewals and amendments only the documents that have changed need to be filed.

The older CTE checklist on GPCB's site is longer and asks for items that your design team will have to produce: a site plan showing nearby residences, water bodies and highways, a layout showing vents, stacks, chimneys and emission points, drainage and effluent disposal, an effluent treatment flow diagram, a break-up of water use with a water balance, and, for boilers, the steam generation details. Because a circular says the newer list replaces earlier ones, ask the Board which list applies on the day you file.

How long is consent valid, and what changes in 2026?

We could not open the GPCB notices on CC&A validity, and the Board's pages list them without text, so confirm validity for your category with the regional office. The central position has moved. The Control of Water Pollution (Grant, Refusal or Cancellation of Consent) Guidelines, 2025 were amended by G.S.R. 63(E) on 23 January 2026. The amendment says a consent to operate, once granted, remains valid until cancelled, lets the State fix a one-time fee for a chosen period of 5 to 25 years, and treats consent to establish as deemed granted for micro and small units in notified industrial estates on a self-certified Form I. It also says applications will move to a single online portal run by the Central Pollution Control Board once that portal is operational.

The Water Act amendment of 2024, under which those guidelines are made, applies to Himachal Pradesh, Rajasthan and the Union Territories, and to any other State whose Assembly adopts it by resolution. GPCB lists the amendment among its Acts and Rules, but we could not confirm how the Gujarat Assembly has dealt with it. A compliance-vendor note reports that GPCB has replaced CC&A renewal with an extension fee; we could not verify this from the Board. Ask the Board for the notice that applies to your unit.

Where does the MEP design touch the consent?

Most consent files stall on drawings and numbers, not on forms. The water balance must match the plumbing design and the cooling tower make-up. The effluent or sewage treatment plant in the layout must match the one that is built. DG set stacks, boiler chimneys and process vents need heights and locations on the drawing. A fire-fighting tank and a rainwater system change the water balance as well. Keep the MEP and consent drawings on one revision. For the national picture, see our guide to SPCB consent (CTE and CTO), and for the other pre-start factory approvals see the approvals overview and our note on factory licence and DISH approval.

How Secured Engineers helps

Design is in-house, so the water balance, stack details, STP layout and electrical load are drawn together. Fire NOC, CEIG and DISCOM net-metering filings are done in-house. MEPF and solar can sit under one contract. We work from our Noida (Delhi NCR) and Ludhiana offices, across 535+ projects in 18+ states, and 89.77% of our clients return. For pollution consent, our role is the engineering inputs and drawings that the file needs, alongside your environmental consultant.

If you have a CTE or CC&A file in progress, send the layout, the process flow and the water balance, and we will check the drawings against the checklist before they go in.
