Getting a Pollution NOC (Consent to Establish/Operate) is a mandatory compliance step for manufacturing units in India under environmental laws. The application is addressed to the State Pollution Control Board (SPCB) or Pollution Control Committee (PCC), depending on the location of the unit. The process begins with identifying the industry category—Red, Orange, Green, or White—based on pollution potential. This NOC ensures your business meets statutory pollution control norms under India’s environmental framework. However, rules and regulations for compliance vary across the states.
Understanding Pollution NOC: CTE and CTO
Applying for Pollution NOC, in India, is a two-step consent process managed by the SPCB or PCC and guided by central laws:
Consent to Establish (CTE):
This is the initial NOC required before you can start construction or install machinery at your manufacturing site. It confirms that the proposed unit will meet pollution control norms once established.
Consent to Operate (CTO):
After you install your equipment and pollution control systems (like effluent treatment plants), you must obtain CTO before beginning production. This ensures your unit actually operates within environmental standards.
Classify Your Industry
Before applying, identify your industry’s pollution category:
- Red: Highly polluting
- Orange: Moderately polluting
- Green: Low polluting
- White: Non-polluting (usually exempt from full consent)
Red category approvals typically need renewal more frequently compared to Green category units.
Supporting documents required for pollution NOC
· Land ownership proof
· Project report
· Authorization letters
· Affidavit and undertaking
· Factory licence, trade licence, PAN, identity proofs
· Pollution control system details (ETP, STP, stack emissions, etc.)
The SPCB issues the Pollution NOC after carrying out a site inspection to verify compliance with environmental norms after the online submission through the SPCB portal.
Following details to submitted for pollution NOC
· Manufacturing process
· Raw materials used
· Water and air pollution control measures
· Waste disposal methods
· Detailed site layout plans
Some boards may also require reports on wastewater analysis, air emission estimates, and compliance strategies.
Online submission of application
Most SPCBs allow online submission of application through their respective Consent Management Systems:
- Filling of the application form for CTE and CTO:
Filling the application form for Consent to Establish (CTE) and Consent to Operate (CTO) requires precise disclosure of unit details, production capacity, and pollution control measures. - Uploading of all supporting documents:
Ensure that all the supporting documents are uploaded in clear, legible, and recommended formats. Incomplete or incorrect document uploads may lead to delays or rejection of the application.
- Payment of application and scrutiny fees (Vary from states to states. Also, size of industry.):
The prescribed application and scrutiny fees must be paid online while submitting the Pollution NOC application to the concerned Pollution Control Board. Payment confirmation is essential, as the application is processed only after successful fee submission.
Inspection and Evaluation
After submission, board officials will inspect your site to verify:
- Pollution control equipment installation
- Wastewater and emission control readiness
- Compliance with norms stated in the application
Based on this inspection and document review, the board may grant, modify, or refuse the NOC.
