The clearest evidence that the old figure still governs is what operators write in their own filings. These are read directly from filed documents.
Read these across sectors with care. A percentage of a factory plot and a percentage of a mining lease are not the same measurement — a lease is mostly the mineral body, which is why mine figures sit so much lower without necessarily indicating under-compliance.
Dahanu Thermal Power Station, clinker grinding unit
32.5% → 35.5%- Operator
- Adani Power Limited
- Location
- Agwan, Dahanu, Palghar, Maharashtra
- Sector
- Thermal power and cement
- Plant area
- 351.58 ha
- Green belt
- 114.13 ha existing, rising to 124.82 ha
The filing states the intent to exceed “the 33 % area”, and commits 50.4% of the new grinding unit's own 21.20 ha footprint to plantation. Filed after the October 2025 memorandum reduced the national tiers — evidence that 33% remains the operative planning benchmark in Maharashtra. The site also sits inside the Dahanu Taluka Ecologically Fragile Area, a separate overlay from the critically polluted area regime.

Rain Cements limestone mine, capacity enhancement
6.3% → 7.9%- Operator
- Rain Cements Limited
- Location
- Revoor and Mellacheruvu, Suryapet, Telangana
- Sector
- Limestone mining
- Plant area
- 417.95 ha mine lease
- Green belt
- 26.26 ha developed, 6.57 ha further proposed
Far below the figures quoted for factory sites, and a caution against comparing the two. A mining lease is mostly the mineral body itself, so a percentage of lease area measures something quite different from a percentage of a plant plot. Afforestation runs at 2,000 saplings a year, with topsoil laid as the plantation bed. Monitoring is against CPCB and TSPCB guidelines.

Khairulabad Limestone Mine
0%- Operator
- Dalmia Cement (Bharat) Limited
- Location
- Khairulabad, Ariyalur, Tamil Nadu
- Sector
- Limestone mining
- Plant area
- 2.25 ha lease
- Green belt
- Nil on site
The land use table records green belt area as zero at every stage, because the entire 2.25 ha lease is the mine pit — the filing states the lease is compact and contiguous with adjoining leases, so a belt is not developed independently. The obligation is met instead through plantation of about 2,200 trees at 1,500 trees per hectare, phased at 500 a year against a 90% survival target, under Divisional Forest Officer guidance. A useful illustration that a small site with no spare land still carries the obligation — it simply moves off the plot.

Coromandel Limestone Mine, Chilamkur unit
~25%- Operator
- India Cements Limited
- Location
- Chilamkur, Kadapa, Andhra Pradesh
- Sector
- Limestone mining and cement
- Plant area
- 602.14 ha mining lease
- Green belt
- 146.25 ha over the lease period, 182.95 ha over the life of mine
Counts toward the belt: a 7.5 m safety zone along the entire lease boundary, 105 m either side of the railway line crossing the lease (68.28 ha), roadside planting, and reclaimed backfilled areas. 145,000 plants proposed against 12,900 already established over 11.08 ha. Species drawn from CPCB's guidance for cement plants.

Dalla Cement Works expansion
37% → 41.7%- Operator
- UltraTech Cement Ltd.
- Location
- Dalla, Sonebhadra, Uttar Pradesh
- Sector
- Cement
- Plant area
- 67.0 ha
- Green belt
- 25.0 ha existing, rising to 27.92 ha
53,000 saplings at 2,120 per hectare, being raised to 2,500 per hectare by gap filling. Budget of ₹110 lakh across existing and proposed work, about ₹3.94 lakh per hectare. Sonebhadra is a critically polluted area, which is consistent with the 40% figure.
