Industries planning to set up new units or expand existing facilities can apply online for Consent to Establish under the Air (Prevention and Control of Pollution) Act, 1981. The service requires applicants to provide details of proposed activities, emission sources, and pollution control equipment. Authorities review the information to ensure compliance with air quality regulations before granting approval. This process helps regulate industrial emissions, promotes environmentally responsible development, and ensures that businesses adopt proper pollution control measures from the beginning.
