The Statutory Framework Under Water & Air Pollution Control Acts
Under Section 25 of the Water (Prevention and Control of Pollution) Act and Section 21 of the Air Act, no industrial plant or commercial establishment with significant effluent discharge or emission sources can operate without valid Consent to Operate (CTO) from the State Pollution Control Board. Operating without an active consent constitutes a cognizable offense.
Category Lifespans: Red (5 Yr), Orange (10 Yr), Green (15 Yr)
Pollution control boards classify operations into Red (heavily polluting), Orange (moderately polluting), Green (lightly polluting), and White (exempt) categories. Validity lifespans typically range from 5 years for Red category manufacturing plants to 10 or 15 years for Orange and Green installations, requiring meticulous long-horizon tracking.
Mandatory Prerequisites: Stack Monitoring, ETP/STP Reports & Form 5
A CTO renewal cannot be submitted overnight. It requires uploading certified stack emission test results, effluent treatment plant (ETP/STP) treated water lab reports from MoEF-recognized laboratories, and copies of the latest annual Environmental Statement (Form V). Gathering these audit reports takes at least 45 to 60 days.
