Understanding CPCB and Polluting Industries Classification

The Central Pollution Control Board (CPCB) is a statutory organization in India, established in 1974 under the Water (Prevention and Control of Pollution) Act, 1974. It was later entrusted with the powers and functions under the Air (Prevention and Control of Pollution) Act, 1981. The CPCB plays a crucial role in controlling pollution levels across the country.

One of the key functions of the CPCB is to classify industries based on their potential to pollute the environment. This classification helps in setting priorities for monitoring, inspection, and enforcement of environmental regulations. The industries are broadly categorized based on factors like consumption of water, generation of wastewater, generation of hazardous waste, and emissions into the atmosphere.

Based on the pollution potential, the CPCB has categorized industries into different groups. For the purpose of regulation and monitoring, a specific number of categories of large and medium scale industries were identified as significantly polluting.

The Central Pollution Control Board (CPCB) has identified 17 categories of large and medium industries as polluting industries. These specific categories are considered to have a high potential for generating pollution and therefore require stringent environmental controls and regular monitoring by regulatory bodies.

This classification into 17 categories is a significant aspect of India's industrial environmental regulation framework, helping focus efforts on the most impactful sectors.

Additional Information on CPCB and Industrial Pollution Control

Apart from the 17 categories of large and medium polluting industries, CPCB also uses a four-colour system (Red, Orange, Green, White) to classify industries based on their Pollution Index (PI). This PI indicates the pollution potential of an industrial sector. The classification is as follows:

• Red Category: Industries with PI score of 60 and above. These are the most polluting industries (the 17 categories often fall under this).
• Orange Category: Industries with PI score between 41 and 59. These have moderate pollution potential.
• Green Category: Industries with PI score between 21 and 40. These have low pollution potential.
• White Category: Industries with PI score below 20. These are non-polluting industries.

This comprehensive classification system helps regulatory bodies like CPCB and State Pollution Control Boards (SPCBs) manage environmental clearances, consents, and monitoring activities effectively, ensuring better pollution control across different industrial sectors in India.
