A number buried in an RTI response can say more about a plant's real emissions than years of routine compliance filings. This one says a lot.
What the RTI Disclosure Shows
Records obtained through a Right to Information request by environmental activist Amit Gupta show that the state-run Deen Bandhu Chhotu Ram Thermal Power Project in Yamunanagar, Haryana, recorded particulate matter (PM) emissions of 1,939 mg/Nm³ from one of its units during a February 2026 inspection, against a legal limit of 50 mg/Nm³, a breach of roughly 38.8 times the permissible level. A second unit tested the same week came in closer to the limit, at 63.9 mg/Nm³. The Central Pollution Control Board (CPCB) has levied a penalty of ₹31.46 crore covering the violation period.
The plant, operated by Haryana Power Generation Corporation, comprises two 300-megawatt units commissioned in 2008 and is classified as a "highly polluting" Category C thermal facility under CPCB's own categorisation.
Why the Gap Is This Large
A PM reading 38.8 times the legal limit is not a marginal exceedance that slipped through a routine check. It typically points to either a malfunctioning or bypassed pollution control device, such as an electrostatic precipitator operating well below its rated efficiency, or ash-handling and combustion issues compounding each other inside an aging unit. Thermal plants built in the mid-2000s were not originally designed around today's tighter particulate norms, which is part of why retrofit compliance has been such a persistent problem across India's older coal fleet.
This is not an isolated finding for the region. A broader review of Delhi-NCR's thermal power plants by the Centre for Science and Environment has previously flagged widespread non-compliance with MOEFCC emission norms across the sector, with several plants missing nitrogen oxide and sulphur dioxide control deadlines as well.
What the Penalty Actually Changes
A ₹31.46 crore penalty is a meaningful cost, but penalties alone do not fix a precipitator or retrofit a bag filter. The compliance deadline originally set for particulate matter and nitrogen oxide controls at this plant has already passed, which is part of what makes an RTI disclosure like this one land as current news rather than old history: it surfaces, well after the fact, how far short of the standard the plant was actually running.
For any industrial or power facility carrying this kind of compliance gap, the practical fix is the same regardless of the penalty amount: properly sized, continuously monitored emission control equipment, verified against actual stack readings rather than design specifications. Continuous emission monitoring systems exist precisely to catch a gap like this before it becomes a multi-crore liability, rather than after.
Key Highlights
- A Yamunanagar thermal plant unit recorded PM emissions 38.8 times the legal limit during a February 2026 inspection
- CPCB has imposed a ₹31.46 crore penalty on the plant's operator
- The facility is a CPCB-classified "highly polluting" Category C thermal plant
- The finding came to light through an RTI disclosure, not a routine compliance announcement
