What is a Pollution Control Board Licence?

A Pollution Control Board (PCB) Licence is a mandatory environmental clearance issued by the Assam Pollution Control Board (APCB) under the Water (Prevention and Control of Pollution) Act, 1974 and the Air (Prevention and Control of Pollution) Act, 1981.

Any industrial, manufacturing, or commercial unit that generates pollution (air, water, noise, or hazardous waste) must obtain PCB consent before establishing or operating in Assam.


⚠️ Legal Consequences

Operating without APCB consent can result in heavy penalties, closure orders, criminal prosecution, and cancellation of business licences. Ensure compliance before starting operations.
