MPCB Consent to Establish & Operate — Maharashtra
Also known as: MPCB consent, pollution NOC, consent to establish, consent to operate, MPCB licence, CTE CTO Maharashtra
Most industries need consent from the Maharashtra Pollution Control Board (MPCB) under the Water and Air Acts — Consent to Establish (CTE) BEFORE you build, then Consent to Operate (CTO) BEFORE you start production. What applies depends on your pollution category (Red / Orange / Green / White); White-category, practically non-polluting activities are exempt. CTO is time-limited and must be renewed.

Common questions
Do I need MPCB consent for a small unit?
It depends on your pollution category. Red, Orange and Green categories need consent; White-category, practically non-polluting activities are exempt. Confirm your category on the MPCB classification.
What's the difference between CTE and CTO?
Consent to Establish (CTE) is needed before you build/install; Consent to Operate (CTO) before you start production, and it's granted only if you've implemented the pollution controls promised at CTE.
How long is Consent to Operate valid?
Commonly five years (up to ten for some categories), then renewable. Renew before expiry to keep operating.

- 15 July 2026 — Initial authoring: MPCB Consent to Establish & Operate (MH) under the Water/Air Acts — category-driven (Red/Orange/Green/White, White exempt), CTE-before-build / CTO-before-operate sequence, ~5-year CTO renewal. Category classification, fee schedule, timelines and White-exemption scope flagged heavily for verification against MPCB.
