Pollution Control Board Registration in Tamil Nadu - Process, Fees
Before starting any manufacturing entity in Tamil Nadu, Occupiers are required to complete Tamil Nadu Pollution Control Board registration. It is considered important due to the increased pollution index.
Earlier, it was handled under the Water (Prevention and Control of Pollution) Act, 1974. The Government of Tamil Nadu established the Tamil Nadu Prevention and Control of Water Pollution Board on February 27, which was renamed the Tamil Nadu Pollution Control Board (TNPCB).
The Board inspects, gathers, and disseminates data about water, air, and noise pollution, along with enacting the standards for sewage effluent and emissions entrusted to it. TNPCB spreads awareness in Tamil Nadu through training institutes, awareness units, and initiating environmental awareness programs.
Business who fails to get approval for establishment or operating a manufacturing entity are prone to engaging in legal and court cases. TNPCB can issue immediate closure of the unit and utility discontinuation.
