Let our experts help you obtain TNPCB NOC hassle-free

TNPCB (Tamil Nadu Pollution Control Board) was formed on 27th February 1982. The Board grants TNPCB consent certificates to new industries in two stages. Consent to establish (CTE) is granted based on the site's suitability before the industry starts the construction activities. Consent to operate (CTO) is granted after the installation of pollution control measures by the facility to satisfy the standards.

Tamil Nadu Pollution Control Board (TNPCB) - Overview

The Tamil Nadu Prevention and Control (P&C) of Water Pollution Board was established by the Government of TN in pursuance of the Water (P&CP) Act, 1974 (Central Act 6 of 1974). It was later renamed Tamil Nadu Pollution Control Board (TNPCB) in 1983. Besides the Acts stated above, the Board enforces the norms of the Environment (Protection) Act (EPA), 1986 and the rules made under these Acts. The Board, therefore, issues TNPCB NOC to the state's commercial activities, industries or projects.

TNPCB operates with its 38 District Offices (DO), eight Zonal Offices (ZO) and Head Office (HO) in Chennai. The Chairman leads the Board office, the Joint Chief Environmental Engineers lead the ZO, District Environmental Engineers lead the DO, and Assistant Environmental Engineers lead the 3 AEE offices. Five flying squads also function at Erode, Chennai, Salem, Vellore and Tiruppur. The Environmental Engineers lead these squads. To assist in the Scientific and Analytical side, the Board has set up eight Districts and eight Advanced Environmental Labs.

TNPCB is implementing the Pollution Control Legislations, Notifications and Rules framed therein. In discharging the duties endowed to it, the Board collects, examines and disseminates info concerning air, water and land pollution, and sets standards for trade effluent/sewage and emissions.

To grant TNPCB consent certificates, the following process is followed. The field officers of the Board examine every industry under their jurisdiction periodically to assess the adequacy of treatment measures given to treat the gaseous and effluent emission.

TNPCB takes legal actions, issues show cause notices and instructs for the stoppage, closure of power and water supply etc., against erring agencies/industries for non-compliance with pollution control legislations, standards and conditions.

TNPCB has entitled the power to the field officers for close examination. The District Environmental Engineers/Joint Chief Environmental Engineer are entrusted to renew/issue TNPCB consent certificates to green, orange, and red small-category industries. They are also assigned to issue show-cause notices to all industries.

The State Board plays a catalytic role in implementing Common Effluent Treatment Plants (CETPs) for small-scale units such as textile dyeing units, tanneries, etc., situated in clusters. TNPCB is following the practical steps for the safe disposal of hazardous waste. The Board has completed the inventory of hazardous waste-producing units and identified locations for hazardous waste disposal.

Additionally, the State Board creates environmental awareness in Tamil Nadu via the Environmental Awareness Cell, Environmental Training Institute, Environmental Awareness Programme, etc.

State Pollution Control Board, Odisha Consent to Establish (CTE)

As per norms of the Water (P&CP) Act, 1974 and Air (P&CP) Act, 1981, all new proposing projects (Developmental and Industrial) must obtain "Consent to Establish (CTE)" (popularly termed as SPCB NOC ) from the Board. SPCB-O CTE is obtained by applying to Board with specified fees, necessary documents, and information via online services.

Industry categorisation

The industries are categorised as Orange, Red, Green and White depending upon the pollution and hazard capacity of industrial activities. The industrial projects are further classified into Category A, B and C, depending on the investment and pollution capacity.
