Complete Guide to MPCB Authorisation for New Industries in Maharashtra

What is Maharashtra Pollution Control Board (MPCB)?

• The Maharashtra Pollution Control Board (MPCB) is a government organisation in the state of Maharashtra, India.
  
  

• MPCB’s job is to make sure that industries follow laws about pollution — that means making sure factories don’t dirty the air, water, or land in a harmful way. Nonconsultants.
  
  

• So, if you want to start a factory or a mill (for example a flour mill or paddy-processing unit) in Maharashtra, you must get approval from MPCB before you begin.
  
  

  
  

Why do you need MPCB Authorisation (Consent / Licence)?

• Before building or starting work on any industrial unit, the unit must obtain a legal permission from MPCB — known as Consent to Establish (CTE).
  
  

• Once the factory or unit is ready to operate (machines installed, pollution-control systems in place, etc.), you need another permission — Consent to Operate (CTO).
  
  

• If you start operations without these consents, you break the law. MPCB can force you to shut down the factory and even take legal action.
  
  

• These consents also ensure you plan and build pollution-control measures properly — like systems to manage wastewater, air emissions, waste, and other pollution risks.
  
  

Who gets affected — in simple words

If you are thinking of starting any of these in Maharashtra, you likely need MPCB permission:

• A flour mill business — where you grind wheat or other grains into flour.
  
  

• A paddy processing industry — where you clean, mill, polish, or package rice/paddy.
  
  

• Any other manufacturing or industrial business that may produce air pollution, waste water, or solid waste.
  
  

Special Cases: Flour Mill Business & Paddy Processing Industry

Flour Mill Business Set Up in India

• Generally, a flour mill uses grains (like wheat) and machines for grinding. Even though food-processing may seem “clean,” you still need to get permission (NOC / consent) from the local pollution-control board because there can be dust, waste, emissions, or wastewater.
  
  

• To run a flour mill, you often need: your business registration (proprietorship, partnership, company), registration with small-scale or medium-scale business registries (if applicable), and important licences like food-safety licences if you plan to sell flour.
  
  

Paddy Processing Industry Set Up

• Paddy processing means cleaning raw paddy (rice), removing husk, milling, polishing, packaging etc. This process can generate dust, husk waste, and sometimes wastewater.
  
  

• Because of that, such units must get formal permission — first CTE (before building), then CTO (before starting operations) — from MPCB or the relevant pollution-board.
  
  

• They may also need other licences: factory-licence (as per law in India), registrations (company or proprietorship), GST, registration under small/medium industry scheme, maybe import/export code if they export rice, food-safety licence, and so on.
  
  

What Documents & Steps Are Needed to Get MPCB Authorisation

Getting MPCB consent is like applying for permission — you need to show them the full plan of your factory so they can check if you will harm environment or not. Here’s how it works, step by step:

Step-by-Step Application Process

1. Register & Create Account Online
   
   

• Visit MPCB’s online portal (called “MAITRI / ec-MPCB”).
  
  

• Do a one-time registration. You’ll need details like industry name, address, owner’s name, contact number, etc.
  
  

2. Verify and Upload Basic Documents
   
   

• During registration, you must verify your mobile number (via OTP).
  
  

• Upload basic documents: identity proof of the authorized person (like Aadhaar or PAN), company’s registration certificate or partnership deed, and board resolution or list of directors/partners.
  
  

3. Apply for Consent to Establish (CTE)
   
   

• After registration, choose service “Consent to Establish — New”.
  
  

• Along with application form, you must submit detailed documents: site plan/layout plan, report of project (how you will build plant), details of machinery, capital investment (land + building + machines), plan for pollution control systems (air, water, waste), water-usage plan, waste discharge/emission points, etc.
  
  

• Also you need proof of land (ownership or lease), industry registration, sometimes NOC from local authorities (if required).
  
  

• Pay the consent/processing fees (fee depends on capital investment and category).
  
  

4. Application Review & Site Inspection by MPCB
   
   

• Once submitted, your application is reviewed. Documents are checked. Then a field officer from MPCB may visit your site to verify that everything is genuine (land, plan, pollution-control measures) before granting CTE.
  
  

• If everything is fine, MPCB approves your application and provides signed Consent to Establish certificate. Otherwise they may reject or ask for corrections.
  
  

5. Set up the Factory
   
   

• Once you have CTE, you can build the plant / install machinery / set up pollution-control systems as per plan.
  
  

6. Apply for Consent to Operate (CTO)
   
   

• After construction and installation are complete, but before you start actual production or trial runs, you must apply for CTO.
  
  

• For CTO, you need to submit proof that pollution-control measures are in place, layout plan, list of machinery, water treatment systems (if any), waste disposal arrangements, previous CTE copy, financial documents (like balance sheet or capital investment certificate), etc.
  
  

• Once your application is verified and you comply with all conditions, MPCB issues Consent to Operate. Then you can legally produce and sell goods from your factory.
  
  

7. Renew Consent When Needed
   
   

• Consent to Operate is valid for a certain period depending on category (e.g., Green/Orange/Red). You must apply for renewal before it expires.
  
  

• If you don’t renew, MPCB may order closure or impose fines.
  
  

Industry Categories — Pollution Potential & How MPCB Divides Them

MPCB classifies every industry into a “pollution category” based on how much pollution it may create. This classification decides how strict the rules and checks will be. 

• Green — Low pollution potential (least risky).
  
  

• Orange — Moderate pollution potential (medium risk).
  
  

• Red — High pollution potential (most risky).
  
  

• There is also a “White” or “Very Low” category for certain small/harmless businesses.
  
  

Usually, a flour mill or paddy processing unit falls in Green or Orange category (because these are food-processing units — not super-hazardous like chemical factories).

The pollution-category matters because it affects:

• How much paperwork you need
  
  

• How strict the pollution-control requirements are
  
  

• How often you need to renew consent
  
  

What Happens If You Don’t Get MPCB Authorisation

• If you start building or operating without CTE or CTO, you break the law.
  
  

• MPCB can force you to stop operations. They may order closure of the unit.
  
  

• You may also face heavy fines or other legal penalties (depends on how serious the violation is).
  
  

• Also, if you commit environmental damage — like dumping waste illegally or polluting water/air — you may need to pay for cleaning up and restoring the polluted area.
  
  

What else you need besides MPCB Consent

Setting up a business like a Flour Mill or Paddy-Processing unit involves more licences beyond MPCB consent. For example:

• Business registration — proprietorship / partnership / company.
  
  

• If you are dealing with food (like flour or rice), you might need a food-safety licence.
  
  

• Registration under MSME or small-scale industry schemes (if applicable).
  
  

• GST registration (for tax purposes).
  
  

• If exporting goods (like rice), you may need an Import Export Code (IEC).
  
  

• Factory licence (as per national rules, if your unit qualifies as a “factory”.
  
  

• Local-body permissions (if required), electricity-connection, building permissions, safety/health approvals, etc.

So, setting up a mill is not only about building machines — you must carefully ensure legal and environmental compliance.

Frequently Asked Questions (FAQs)

Q1. What is the difference between “Consent to Establish (CTE)” and “Consent to Operate (CTO)”?

• CTE is permission to build or set up the factory — given before construction starts.

• CTO is permission to run the factory — given only after setup is complete and pollution-control measures are in place. 

Q2. My business is a small flour mill — do I still need MPCB consent?
Yes. Even food-processing units like flour mills or rice/paddy processing generate dust, waste, emissions, or wastewater. So you must get both CTE and CTO before starting. 

Q3. How long does MPCB take to approve consent?
Typically, it can take up to 90 days (about 3 months) for MPCB to decide on a consent application — though the time may vary depending on complexity.

Q4. What if I start production without consent?
That is illegal. MPCB may order closure of your unit, impose fines or other legal penalties. You may also be responsible for cleaning or restoring any environmental damage.

Q5. Is MPCB consent enough — or do I need other licences too?
No — MPCB consent is just one part. For a business like flour mill or paddy processing, you also need business registration, factory licence (if applicable), food-safety licence (if handling food), GST, possibly export/import licence, and local-authority permissions.
