If your new unit is likely to discharge trade effluent, emit anything into the air, or handle hazardous waste, you need Consent to Establish (CTE) from the Maharashtra Pollution Control Board before you start construction. Not after the shed is up.
What CTE actually is
The MPCB issues a combined consent under the Water (Prevention and Control of Pollution) Act, 1974 and the Air (Prevention and Control of Pollution) Act, 1981, along with authorization under the hazardous waste rules where applicable. CTE is the first of these approvals. CTE means the Maharashtra Pollution Control Board's consent to establish your unit. It tells the Board what you plan to build, what you will discharge or emit, and what pollution control systems you will install. Consent to Operate (CTO) comes later, once the unit is built and the promised systems are actually in place.
Step 1: Confirm your category first
Before touching the application, confirm whether your activity falls under the Red, Orange, Green or White category. The category is based on the pollution potential of your process, and it decides your fees, the scrutiny level, and whether you need consent at all. White category units only need to intimate the Board. Everyone else needs CTE.
Step 2: Prepare the application and documents
Applications go through MPCB’s online consent portal. The typical document set includes proof of land possession or lease, an approved layout plan / Local body NOC, details of the manufacturing process with a flow diagram, water budget (source, consumption, and effluent quantity), details of proposed effluent and air pollution control systems, and capital investment proof. Units in MIDC areas also attach the MIDC allotment letter. If your project needs Environmental Clearance under the EIA Notification, 2006, that is a separate approval, and for the first CTO the Board will ask for a copy of it.
Step 3: Pay fees and submit
Consent fees are linked to your capital investment and category. The fee schedule is published on the MPCB website and changes from time to time, so check the current version rather than relying on an old quotation.
Step 4: Scrutiny, site visit and grant
The regional or sub-regional office scrutinises the application. Queries are raised online and every query resets your effective timeline, which is why a complete first submission matters more than a fast one. Depending on the category and location, a site inspection may be carried out. Once the Board is satisfied, CTE is granted with conditions. Read the conditions carefully. They become your compliance obligations, and they are checked when you apply for CTO.
Where applications get stuck
In our experience the usual culprits are incomplete details, wrong water budgets, mismatch between the layout plan and the described process, missing land documents. A clean, honest application moves faster than a clever one.
