No industrial or commercial project in India can legally operate without obtaining permission from the State Pollution Control Board (SPCB) or Pollution Control Committee (PCC). Every industry — whether classified under the Red, Orange, Green, or White category — must comply with the Consent Management System as per the Water (Prevention and Control of Pollution) Act, 1974, the Air (Prevention and Control of Pollution) Act, 1981, and the Environment (Protection) Act, 1986.
Under this system, industries must secure a Pollution Control Board NOC, which includes:
- ✅ Consent to Establish (CTE) – before starting construction or installation.
- ✅ Consent to Operate (CTO) – before beginning operations or production.
- ✅ Consolidated Consent and Authorisation (CCA) – combined approval for consent and waste authorisation (applicable in certain states).
Operating without these Pollution NOCs is considered illegal. The SPCB has the authority to disconnect electricity and water supply, impose penalties, and even order closure of non-compliant industries.
This is where Pollution Consulting Services come in. At Simplicomp Tech LLP, we provide expert guidance and end-to-end support for CTE, CTO, and Pollution Control Board NOC approvals—helping industries navigate regulatory complexities efficiently and legally.
🧾 Types of Pollution Control Board NOCs
1. Consent to Establish (CTE) NOC
What It Is:
The CTE NOC is a pre-establishment clearance issued by the Pollution Control Board before construction or installation of any project or machinery begins.
Legal Basis:
- Section 25–27 of the Water Act, 1974
- Section 21 of the Air Act, 1981
Why It Matters:
Without obtaining a CTE approval, no industry can legally install pollution control devices like STP, ETP, chimneys, scrubbers, or other emission systems.
Documents Required for CTE Application:
- Land ownership/lease / allotment documents
- Capital investment certificate from Chartered Accountant
- Manufacturing process details & flowchart
- Design details of STP/ETP and Air Pollution Control Devices (APCDs)
- Forest NOC (if applicable under Aravali Notification)
- Wildlife NOC (if within 10 km of protected area)
- Environmental Clearance (EC) under EIA Notification, 2006 (if applicable)
- Site layout plans and maps
- Authorization letter / Board resolution
- CTE fees and security deposit
Validity of CTE:
- Red Category: 1–3 years
- Orange Category: 2–5 years
- Green Category: 1–10 years
2. Consent to Operate (CTO) NOC
What It Is:
The CTO NOC is the operation-stage clearance required before an industry begins production. It ensures that all pollution control systems are installed and functioning as per norms.
Legal Basis:
- Water Act, 1974
- Air Act, 1981
- Environment Protection Act, 1986
Why It Matters:
Industries must demonstrate that pollution control equipment (ETP, STP, scrubbers, filters, ESPs) are working effectively before they can legally operate.
Documents Required for CTO Application:
- Land/lease/allotment documents
- Balance sheet and investment details
- Manufacturing process & flow diagram
- Pollution control equipment details (STP, ETP, APCDs)
- Forest and Wildlife NOCs (if applicable)
- Environmental Clearance (EC) copy
- Site layout and green belt plan
- Water/effluent analysis report
- Borewell Groundwater NOC (CGWA) if using groundwater
- Proposal for online emission & effluent monitoring systems
- CTO fees and authorization letter
Validity of CTO:
- Red Category: 1–3 years
- Orange Category: 1–5 years
- Green Category: 1–15 years
3. Consolidated Consent and Authorisation (CCA)
What It Is:
In certain states like Uttarakhand (UEPPCB) and Gujarat, industries are issued a Consolidated Consent and Authorisation (CCA) which merges CTO and Hazardous Waste Authorization into a single approval.
Legal Basis:
- Water Act, 1974
- Air Act, 1981
- Environment Protection Act, 1986
Validity of CCA:
- Red Category: 1 year
- Orange Category: 5 years
This system reduces administrative complexity and ensures simplified pollution control compliance.
⚙️ Pollution NOC Process Flow
While procedures differ slightly between states, the general Pollution NOC process includes the following steps:
- Application Filing – Submit online application on respective SPCB portal.
- Document Upload – Attach all required technical, legal, and environmental documents.
- Scrutiny by Pollution Control Board – SPCB officials review the application.
- Inspection – Site visit and verification by Pollution Control Board officers.
- Approval / Conditional NOC – Grant of CTE, CTO, or CCA along with specific compliance conditions.
⚠️ Consequences of Non-Compliance
Operating without valid Pollution Control Board NOCs violates environmental laws and attracts strict enforcement actions.
- SPCB can seal operations, disconnect utilities, and impose penalties.
- Non-compliant industries face environmental compensation orders from the National Green Tribunal (NGT).
- Repeat violations may lead to legal prosecution and permanent closure.
