Byrnihat pollution has come under renewed scrutiny after a recent inspection found 28 of 37 industries in the industrial area violating environmental norms.
The inspection and subsequent action by the Meghalaya State Pollution Control Board (MSPCB) were placed before the Meghalaya High Court in a status report in August. The court is monitoring a public interest litigation concerning air pollution, industrial activity and pollution of the Umtrew River in Byrnihat.
Byrnihat pollution check finds widespread violations
The inspection findings indicate that non-compliance remains a significant concern among industries operating in and around Byrnihat. Of the 37 units assessed, 28 were found to have violated prescribed norms, highlighting gaps that regulators say require corrective action.
The violations relate to environmental compliance, including air quality and effluent standards. The MSPCB has issued show-cause notices, closure directions and other regulatory measures depending on the nature of the violations.
However, the inspection does not mean every industrial unit was found to be emitting above permissible limits at the same time. A joint site inspection on August 4 found that industries in the Export Promotion Industrial Park were continuously monitoring emissions, while recorded smoke emissions were within permissible limits during the inspection.
Action intensifies over Byrnihat pollution
The MSPCB has already taken action against several units. The High Court record says Umiam Distillation Private Limited received a closure notice on August 11 after failing to respond to a show-cause notice issued on July 28. The Board directed the unit to close until further orders.
Shyam Century Ferrous Limited was also directed to shut down following an earlier notice. Meanwhile, the consent to operate of Bodhi Premier LLP was suspended on August 5 after show-cause notices were issued.
CMJ Breweries was served a notice after discharged water failed to meet the prescribed limit under an Environment Protection Act notification.
Byrnihat pollution linked to air and water concerns
The High Court-appointed amicus curiae inspected the Umtrew River and reported extensive garbage dumping along the riverbank beneath the Byrnihat highway bridge.
Six industries were identified in the MSPCB status report as contributing to Umtrew River pollution. Four were classified as red-category units, while two were in the orange category. The industries named were Umiam Distillation, CMJ Breweries, Spy Agro Industries, Galeno Metallics, Nalari Ferro Alloys and Bodhi Premier.
The court has directed authorities to address domestic sewage, wastewater and solid-waste management along the river. It also called for stronger coordination between agencies because pollution sources cross administrative boundaries.
Health concerns add to Byrnihat pollution debate
The latest findings come as health concerns remain part of the wider Byrnihat pollution debate. The High Court report noted that acute respiratory illness cases recorded at the Byrnihat Primary Health Centre rose from about 1,800 in 2021 to 7,284 in 2025.
The court also recorded that around 410 chest X-rays were conducted between April 2025 and June 2026, with abnormalities found in about 273 patients. These figures do not by themselves establish that industrial pollution caused the illnesses, but they have added urgency to health monitoring.
A separate research study on the association between ambient air pollution and respiratory symptoms in Meghalaya has received approval, with Byrnihat identified as a priority area.
Stricter monitoring expected in Byrnihat
Byrnihat pollution remains a continuing regulatory challenge because the industrial area spans both sides of the Meghalaya-Assam border.
The Meghalaya State Pollution Control Board’s own monitoring data also show that air quality remains a concern. Byrnihat is also a notified non-attainment town under the National Clean Air Programme. In the second week of August, the EPIP monitoring station recorded an AQI of 109, classified as “Moderate”, while stations at 17th Mile and 15th Mile recorded 68 and 80 respectively.
The High Court has directed the MSPCB to submit a fresh status report on action taken against industries, including the outcomes of show-cause notices. The matter is scheduled to be considered again on September 10, when the court is expected to review the latest compliance report.
For residents and regulators, the findings underline the need for consistent enforcement rather than short-term action. With industrial compliance, river pollution, road dust and public health under scrutiny, Byrnihat pollution is likely to remain a major environmental issue in Meghalaya.
