Down To Earth on 12 May 2026 published its Daily Court Digest summarising three major environment orders affecting India's biodiversity hotspots, mining belts and groundwater regime. First, the National Green Tribunal heard Oil India Limited's defence of its Extended Reach Drilling (ERD) project inside the eco-sensitive zone of Dibru-Saikhowa National Park in Assam; the company argued that the project was granted environmental clearance under Supreme Court and National Board for Wildlife oversight purely for research purposes with no commercial extraction. Second, the Central Pollution Control Board, in an inspection report placed before the NGT, found that hexavalent chromium (Cr VI) concentration in the treated effluent at the Kaliapani Chromite Mines of Jindal Stainless Limited in the Sukinda Valley of Odisha was 0.16 milligram per litre, more than three times the prescribed standard of 0.05 milligram per litre, with the effluent being discharged into the Dharamshala Nalla which meets the Brahmani river. Third, the NGT directed Ultratech Cement's Bichhapuri coal mine in Shahdol, Madhya Pradesh, to construct groundwater recharge structures in nearby villages and ensure regular drinking water supply to Senduri-Baigatola, Kalyanpur and Bicharpur villages where water service has been disrupted. Hexavalent chromium is a recognised carcinogen and Dibru-Saikhowa should not be described as a Ramsar Site; PIB lists Assam's Ramsar Site as Deepor Beel. The Sukinda Valley historically holds about 95 per cent of India's chromite reserves and has long been listed among the most polluted industrial zones in the world.
Daily Environment Court Digest of 12 May 2026 Shows NGT Hearing on Oil India ERD Drilling in Dibru-Saikhowa National Park, CPCB Finding of Hexavalent Chromium Above Limits at Sukinda Valley Mines and Direction to Ultratech Cement Bichhapuri Coal Mine on Groundwater Recharge
Down To Earths 12 May 2026 court digest covers NGT hearing on Oil India ERD drilling in Dibru-Saikhowa, CPCB finding of hexavalent chromium at 0.16 mg/L (limit 0.05 mg/L) at Sukinda Valley mines, and direction to Ultratech Bichhapuri coal mine to build groundwater recharge structures.

Practice MCQ from this story
SolveTap an option below. Correct or incorrect feedback appears instantly.
Consider the following two statements: 1. Dibru-Saikhowa National Park lies in the Tinsukia-Dibrugarh districts of Assam and is a Ramsar Site. 2. The Sukinda Valley in Odisha holds about 95 per cent of India's chromite reserves. Which of the statements given above is/are correct?
Only statement 2 is correct. Dibru-Saikhowa is in the Dibrugarh and Tinsukia districts of Assam and is listed by the Assam Environment and Forest Department as a biosphere reserve, but Assam's Ramsar site entry is Deepar Beel, not Dibru-Saikhowa. The Sukinda ultramafic complex in Jajpur district contributes nearly 95 per cent of India's chromite reserves.

Frequently asked questions
Where is the Sukinda Valley and why is it environmentally significant?
Sukinda Valley lies in the Jajpur district of Odisha. It holds about 95 per cent of Indias chromite reserves and has long been listed among the most polluted industrial zones in the world due to hexavalent chromium discharges.
What was the CPCB finding cited in the 12 May 2026 digest?
CPCB reported that hexavalent chromium concentration in the treated effluent at the Kaliapani Chromite Mines of Jindal Stainless Ltd was 0.16 mg/L, more than three times the prescribed limit of 0.05 mg/L, with discharge going into the Dharamshala Nalla which meets the Brahmani river.
Where is Dibru-Saikhowa National Park located?
Dibru-Saikhowa is in Tinsukia and Dibrugarh districts of Assam; it is a Ramsar Site and an Important Bird Area, and Oil Indias ERD drilling project has been heard by the NGT for its impact on the eco-sensitive zone.
What did the NGT direct for the Bichhapuri coal mine?
The NGT directed Ultratech Cements Bichhapuri coal mine in Shahdol, Madhya Pradesh, to construct groundwater recharge structures in nearby villages and ensure regular drinking water supply to Senduri-Baigatola, Kalyanpur and Bicharpur villages.
