Pollution Control Board NOC (CTE & CTO)

Setting up or running a unit? Many businesses need Pollution Control Board consent. We assess your category and obtain your Consent to Establish and Consent to Operate.

What it is

Businesses whose operations can affect the environment need consent from the State Pollution Control Board under the Water and Air Acts — a Consent to Establish (CTE) before setting up, and a Consent to Operate (CTO) before running. Units are classified (white/green/orange/red) by pollution potential, which decides the requirements. Many tenders and other licenses also ask for a valid PCB consent.

Who should register

Manufacturing units, factories, workshops, hotels and other establishments with environmental impact.
