SIVASAGAR: The Parivesh Suraksha Samity (PSS), a society for conservation and protection of nature and bio-diversity, submitted a memorandum to Sivasagar Deputy Commissioner against Oil and Natural Gas Corporation (ONGC) for allegedly causing air, noise and water pollution in the Geleky area. The organization demanded immediate steps from the district administration as the residents and animals of the surrounding areas allegedly suffer from many unknown diseases and their health is deteriorating due to the pollution. They blamed it all on ONGC for pollution in the area. The incessant flames that have been rising from the oil rigs made the environment more worse. To maintain the environment at the Geleky area, a tree planation drive was carried out by ONGC 10 years ago, which also failed with due course of time, stated the memorandum.
