Consent to Establish (CTE)

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.

CTE is approval before setup. Documentation, pollution control planning, site details, DPR, water balance, and authority coordination must be correct from day one.

When is CTE Required?

CTE must be obtained before:

Starting construction of a facility

Installing plant and machinery

Expanding an existing unit

Changing production processes or capacity

Without CTE, project setup is considered non-compliant and may face regulatory action.

Industry Categorization (Foundation of CTE)

Before applying, the unit must be categorized based on pollution potential:

RED CATEGORY

High pollution industries

ORANGE CATEGORY

Moderate pollution

GREEN CATEGORY

Low pollution

The category determines: Approval requirements, Documentation level, Validity and conditions

Incorrect categorization leads to delays and rejection.

Key Components of a CTE Application

CTE is not just a form — it is a technical evaluation of your project.

Detailed Project Report (DPR)

• 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 Balance & Wastewater Details

• Water consumption estimation
• Effluent generation and characteristics
• Proposed treatment method (ETP/STP)

Air Emission Details

• Sources of emissions (DG sets, boilers, processes)
• Proposed air pollution control systems

Pollution Control Plan

• Effluent Treatment Plant (ETP)
• Sewage Treatment Plant (STP)
• Air pollution control equipment
• Waste management systems

This is one of the most critical parts of the application.

What Most Businesses Miss

CTE is based on proposed systems, not actual installation

This means:

If your design is wrong → CTO will be rejected later

Underestimating pollution load → compliance failure

Poor planning → expensive redesign later

This is where technical expertise matters.

Pollution Control Systems Planning

A strong CTE application includes proper system design.

Greenshield Enviro provides:

Effluent Treatment Plant (ETP) design

Sewage Treatment Plant (STP) design

Oil & Grease Interceptors

Air pollution control systems

Solid waste management solutions

Proper system planning improves approval success rate significantly.

CTE Approval Process

Greenshield Enviro follows a structured approval process covering industry assessment, technical documentation, application filing, authority review, and approval issuance.

Start CTE Process →

Industry Assessment

Identify category and applicable approvals.

Technical Documentation

Prepare DPR, layouts, and environmental data.

Application Filing

Submit application to SPCB/DPCC.

Authority Review

Evaluation based on pollution impact and compliance plan.

Approval Issuance

CTE granted with specific conditions to be followed.

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

Most rejections happen due to poor technical preparation.
