Manufacturing plants, hotels, and healthcare centers face immediate power disconnection and closure if their Consent to Operate (CTO) lapses. Here is how EHS teams manage emission and effluent clearances.

Under the Water (Prevention and Control of Pollution) Act (1974) and the Air (Prevention and Control of Pollution) Act (1981), any commercial establishment or manufacturing facility generating wastewater, air emissions, or hazardous waste must obtain statutory permissions from the State Pollution Control Board (SPCB).
The regulatory process operates in two distinct phases: Consent to Establish (CTE) is a one-time capital permit granted prior to construction or equipment installation. Once construction is complete and pollution abatement systems (ETP, STP, bag filters) are installed, the facility must secure Consent to Operate (CTO). Unlike CTE, CTO is a recurring operational license that must be renewed continuously throughout the operating life of the facility.
The Central Pollution Control Board (CPCB) classifies industrial sectors based on a standardized Pollution Index (PI) score:
| Category | Pollution Index Score | Typical Industries | Standard CTO Lifespan |
|---|---|---|---|
| Red Category | PI Score 60 and above | Chemicals, Pharmaceuticals, Tanneries, Steel, Distilleries | 5 Years (Intense oversight) |
| Orange Category | PI Score 41 to 59 | Food processing, Electroplating, Hotels (> 20 rooms), Casings | 10 Years |
| Green Category | PI Score 21 to 40 | Small assembly units, Bakeries, Dry warehousing, Garments | 15 Years |
| White Category | PI Score up to 20 | Solar power, Wind power, Bio-fertilizers | Exempt from CTO (Intimation only) |
A CTO renewal application cannot be submitted without comprehensive environmental test results:
Because State Pollution Control Boards mandate on-site inspections by Regional Officers (RO) before approving renewals, applications must be submitted on state online portals at least 120 days prior to expiration. Failing to apply within this window results in immediate late fee surcharges and forfeiture of deemed-consent protections.
Using RenewOS, Environmental Health & Safety (EHS) leaders receive automated alerts at 150, 120, and 60 days to schedule testing laboratory sample collections and prepare board filings with zero downtime risk.
