Pollution Concerns at Assam Refinery
Subject: Environment and Ecology
Topic: Pollution Impact

Summary:

A refinery in Golaghat district, Assam, is under scrutiny for allegedly discharging hazardous waste into the Dhansiri River, which is a tributary of the Brahmaputra. Environmental activist Apurba Ballav Goswami has called for an investigation into the Numaligarh Refinery Limited (NRL) due to concerns about its compliance with pollution standards. His request, which was directed to the Central Pollution Control Board (CPCB), was based on a report provided by a private biosciences laboratory that tested a water sample from the NRL’s effluent treatment facility.

The laboratory findings showed that levels of biochemical oxygen demand (BOD), chemical oxygen demand (COD), and oil and grease exceeded the permissible limits set by the CPCB. Specifically, the reported levels were 18.0 mg/litre for BOD (compared to a limit of 15 mg/litre), 142.0 mg/litre for COD (with a limit of 125.0 mg/litre), and 11.5 mg/litre for oil and grease (against a limit of 10 mg/litre). These figures suggest a potential impact on the river's biodiversity and the health of local communities who depend on it.

Mr. Goswami detailed the ecological consequences of these violations, noting that the elevated BOD could lead to reduced oxygen levels vital for aquatic life, thereby threatening species like mahseer and catfish. The high COD reading could create toxic conditions harmful to aquatic organisms, impacting growth and reproduction. Moreover, the oil and grease can deplete oxygen exchange and obstruct aquatic plants, exacerbating the ecological strain.

In response to these allegations, NRL has denied any wrongdoing, suggesting that its effluents are treated properly, and any stormwater discharged does not reach the Dhansiri River directly but is monitored for compliance with pollution norms. They emphasized their commitment to adhering to environmental protection regulations and expressed willingness to cooperate with the CPCB for further investigations.

The NRL was established in 1993 with a refining capacity of nine million metric tonnes per annum and is a critical entity in the region's economy and environment.

Key Points:

  • Site of Concern: A refinery in Golaghat, Assam, is accused of discharging hazardous waste into the Dhansiri River.
  • Complaint Filed: Activist Apurba Ballav Goswami has requested the CPCB to probe the practices of Numaligarh Refinery Limited (NRL).
  • Pollution Analysis: A private lab report indicates that effluent discharge exceeds permissible standards, specific readings being:
    • 18.0 mg/litre BOD (limit: 15 mg/litre)
    • 142.0 mg/litre COD (limit: 125 mg/litre)
    • 11.5 mg/litre oil and grease (limit: 10 mg/litre)
  • Ecological Risks: High BOD levels can create hypoxic zones, impacting fish and aquatic life.
  • Toxicity Concerns: Elevated COD indicates harmful pollutants that can impair aquatic organisms' growth and reproduction.
  • NRL's Defense: NRL denies allegations, stating that effluents are treated and stormwater is monitored for compliance.
  • Cooperation Assured: NRL is open to investigations by the CPCB.
