Pollution NOC (CTE / CTO)
Most industrial units need two consents from the Uttar Pradesh Pollution Control Board under the Water and Air Acts: a Consent to Establish (CTE) before construction, and a Consent to Operate (CTO) before production. The category of your industry decides the depth of scrutiny.
Pollution categories
The Central Pollution Control Board classifies industrial sectors by their pollution potential. State boards apply this classification.
Red
Highest pollution potential. Detailed scrutiny, strict siting conditions and closer monitoring.
Orange
Moderate pollution potential. Consent conditions on effluent, emissions and waste handling.
Green
Lower pollution potential. Simpler consent process, typically with longer validity.
White
Practically non-polluting sectors. Consents are generally not required, though an intimation may be.
CTE and CTO in practice
- 1
Confirm the category
We map your product and process to the CPCB category list. Process choices (for example, the type of boiler fuel or effluent treatment) can change the category, so this is checked before the design is frozen.
- 2
Consent to Establish
Applied before construction with the site plan, process description, water balance, effluent and emission control plan and project cost.
- 3
Consent to Operate
Applied after the control systems are installed and before trial production, demonstrating compliance with CTE conditions.
- 4
Ongoing compliance
Renewals, annual returns, hazardous waste authorisation where applicable, and responses to inspections.
Timelines
CTE and CTO are notified Nivesh Mitra services with a 120-day timeline, counted from a complete application. Because this is one of the longest approvals, it should be filed as soon as the site and process are fixed.
