OVERVIEW · 01
Mandatory Environmental Approval Before Project Setup
Consent to Establish (CTE) is a statutory approval required before setting up any industrial, commercial, or infrastructure project that may have an environmental impact.
The approval is issued by the respective State Pollution Control Board (SPCB) in accordance with guidelines laid down by the Central Pollution Control Board.
CTE ensures that the proposed project complies with environmental norms related to air emissions, wastewater discharge, and waste management before construction or installation begins.
WHEN REQUIRED · 02
When is CTE Required?
CTE must be obtained before the project starts. Without CTE, project setup is considered non-compliant and may face regulatory action.
Starting construction of a facility
Installing plant and machinery
Expanding an existing unit
Changing production processes or capacity
CATEGORIZATION · 03
Industry Categorization (Foundation of CTE)
Before applying, the unit must be categorized based on pollution potential.
High Pollution Industries
High pollution category projects require more detailed documentation and compliance planning.
Moderate Pollution
Moderate pollution industries require category-specific approvals and pollution-control planning.
Low Pollution
Low pollution units still require the correct categorization and applicable approval pathway.
APPLICATION · 04
Key Components of a CTE Application
CTE is not just a form — it is a technical evaluation of your project.
Detailed Project Report
- Nature of industry and process flow
- Installed capacity
- Raw materials and outputs
Land & Site Details
- Location and zoning compliance
- Land ownership or lease documents
- Site layout plan
Water & Wastewater Details
- Water consumption estimation
- Effluent generation and characteristics
- Proposed treatment method (ETP/STP)
Air Emission Details
- Sources of emissions
- DG sets, boilers, and processes
- Proposed control systems
Pollution Control Plan
- ETP and STP
- Air pollution control equipment
- Waste management systems
EXPERT INSIGHT · 05
What Most Businesses Miss
CTE is based on proposed systems, not actual installation.
If your design is wrong, CTO can be rejected later.
Underestimating pollution load can lead to compliance failure.
Poor planning can lead to expensive redesign later.
SYSTEM PLANNING · 06
Pollution Control Systems Planning
A strong CTE application includes proper system design.
Effluent Treatment Plant
ETP design for industrial wastewater and effluent treatment requirements.
Sewage Treatment Plant
STP design for wastewater treatment requirements from facilities and buildings.
Oil & Grease Interceptors
Planning for kitchen, hospitality, and wastewater oil-grease control.
Air Pollution Control
System planning for emissions, DG sets, boilers, and process air management.
Waste Management Solutions
Solid waste management planning aligned with site and approval requirements.
Approval Integration
System design aligned with technical documentation and site requirements.
PROCESS · 07

REJECTION · 08
Common Reasons for Rejection
Most rejections happen due to poor technical preparation.
Incorrect industry categorization
Incomplete DPR or technical details
Unrealistic pollution control plans
Missing system design
Non-compliance with zoning rules
