NGT stays ‘illegal' concrete plant near SGNP
Mumbai: The Pune bench of the National Green Tribunal (NGT) on Wednesday issued an order prohibiting J Kumar Infraprojects Ltd from operating its ready mix concrete (RMC) plant in Thane. The plant, located within the eco-sensitive zone (ESZ) of the Sanjay Gandhi National Park (SGNP), manufactures girders for various ongoing metro rail projects. NGT stays 'illegal' concrete plant near SGNP The bench of justices Dinesh Kumar Singh and Dr Vijay Kulkarni passed the order on a petition filed by Vanshakti, a Mumbai-based nonprofit, which alleged that the RMC plant was functioning illegally, without due permissions, and its operations were destroying the ecology around the Chene and Bhayander Pada villages. In the petition, Vanshakti claimed that over 27 plots in the two forested villages were affected due to the RMC plant. The top soil had been cleared illegally to set up the plant, cement sludge had been dumped on site, and dust emanated constantly from the casting yard of the plant, directly affecting the ecology of the ESZ contiguous to the SGNP, the petition alleged. Transportation of raw materials and cement using multi-axle vehicles, dumpers and trucks further spread dust in the area and affected various sensitive flora and fauna, it noted. The petition further alleged J Kumar Infraprojects Ltd did not have requisite permissions for the plant as the Maharashtra Pollution Control Board (MPCB) had failed to provide to Vanashakti copies of applications by the company to establish and operate the plant as well as site inspection reports. The nonprofit had sought these documents in June 2024 under the Right to Information (RTI) Act, but in July 2024, the MPCB reverted saying the documents were not available on record. The chief conservator of forests and the director of SGNP told the NGT bench via affidavits that the RMC plant was indeed located in the ESZ of the national park. The SGNP's ESZ monitoring committee had inquired via a letter to J Kumar Infraprojects dated January 30, 2025 if the plant had the relevant permissions, the chief conservator of forests said in his affidavit. The committee was also contemplating action on the company under the Environment (Protection) Act, 1986, the affidavit mentioned. Advocate Zaman Ali, appearing for Vanshakti, sought a prohibitory order from the tribunal against the company. The tribunal, after hearing both sides, issued an interim order restricting the company from operating the RMC plant. It will adjudicate on the alleged illegality of the plant in due course. HT reached out to J Kumar Infraprojects' spokesperson for comments on the development, but there was no response from the company.

MOEF team to visit Mahadayi basin projects soon, say officials
A team of officials from the Union Ministry for Forests, Environment and Climate Change is likely to visit the proposed project sites in the Mahadayi river basin in Belagavi district and the adjoining Mhadei Wildlife Sanctuary in the next few days. Official sources said that the team is likely to include forest officials, engineers and hydrologists. Local officials are busy preparing for the visit, like creating multiple copies of documents including the detailed project report of the Bandori Nala Project and the copies of the land acquisition notices issues to farmers. The proposed visit has received contrasting reactions, however, with farmers and pro-Kannada groups in North Karnataka are welcoming it, but environmental activists in Goa and Karnataka opposing the project. The Kalasa - Bandori Nala agitation committee chairman Vijay Kulkarni said he was elated to learn of the visit. 'This means that the Union government has made up its mind to approve of the Karnataka government's plans to utilise Mahadayi basin waters for the development of North Karnataka. We knew this would happen, but it took some time,' he said. The Mahadayi river water diversion project, aimed at supplying water to drought-prone regions of northern Karnataka, has been a long-standing point of contention between Karnataka and Goa. The two lift irrigation projects involve diverting water from the west flowing Kalasa, Bandori, and Haltara streams, that are the tributaries of the Mahadayi into the east flowing Malaprabha. The Union government has approved the two detailed project reports submitted by the State government. However, the final approvals from the Central Wildlife Board and Ministry of Forests are pending. Karnataka argues the Mahadayi basin projects are drinking water projects and are hence exempted from environment impact assessment and public hearing. However, Goa has argued it is an irrigation project that would have irreversible negative impact on the fragile ecology of the western ghats and of Goa. It is in this background that the central team's inspection is seen as a crucial step in evaluating compliance with environmental norms before further approvals are granted. Farmers' associations in North Karnataka and Kannada organisations in Belagavi have expressed optimism about the visit, hoping it will accelerate the project's progress. 'This inspection is a positive step towards resolving the water crisis in our region. The Mahadayi project is essential for irrigation and drinking water needs,' said Uday Desai, a Karnataka Rajya Raitha Sangha leader. Pro-Kannada groups have also urged the central team to expedite clearances, emphasising the project's importance for the State's agrarian economy. We have also heard about the visit, but there is no official confirmation as yet. We would happily welcome the team if they are planning to approve the project, said Ashok Chandaragi, convenor of the central committee of Kannada organisations. Environmentalists, however, are worried. Members of the Paryavarni foundation and the `Save Mahadayi and Save Malaprabha' campaign have called for a rally on June 3, opposing the Mahadayi diversion projects. They have urged the State government to reconsider the projects, as they fear that they would lead to desertification of North Karnataka, that depends on the Khanapur forest region for rainfall. The Mahadayi basin projects would not only lead to submergence of over 50 hectares of forests, choke fresh water supply to the Bhimgad wildlife sanctuary in Karnataka and the Mhadei sanctuary in Goa, but also lead to reduced rainfall in Belagavi and North Karnataka, said Nitin Dhond, a member of the foundation. In a related development, the National Institute of Oceanography (NIO) has submitted a report stating that the Mahadayi project will have a 'minimal impact' on Goa's coastal ecology. The study, commissioned by the central government, claims that the water diversion will not significantly alter salinity levels or marine life in Goa's estuaries. However, Goan activists and some political leaders have dismissed these findings, alleging that the study overlooks long-term environmental risks.

Velsao fish deaths case: NGT disposes of petition
Representative image. Margao: The National Green Tribunal (NGT) disposed of a petition concerning fish mortality at Velsao Bay after noting that the Goa State Pollution Control Board (GSPCB) had already taken appropriate remedial actions against the culpable company. The case came before the western zone bench of the NGT. The petition sought an intervention regarding the mass fish deaths that occurred at Velsao Bay, which were attributed to the effluent discharge from Paradeep Phosphates Ltd (PPL), a fertiliser manufacturing company operating at Zuarinagar, Mormugao. Following a site inspection and the analysis of the water samples from the rivulet, the GSPCB determined that PPL's operations contributed to environmental damage. Subsequently, the board imposed environmental damage compensation of over Rs 12 lakh on the company for the violations. In addition to the monetary penalty, the GSPCB took preventive measures by securing a bank guarantee of Rs 25 lakh from PPL to ensure compliance with the conditions. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like The Highest Earning College Majors—2025 Edition Best Paying Degrees | Search Ads Learn More Undo According to the affidavit submitted by the GSPCB, it conducted a further inspection of the unit in Sep 2024.
