The Navy and the Coast Guard carried out anti-pollution operations for the third consecutive day on Monday to check and neutralise the oil spill caused due to a collision between two cargo ships off the Mumbai coast. Arun Singh, Commandant (Operations), Coast Guard informed that MSC Chitra, a Panamian vessel which collided with another vessel, has tilted 80 degrees leading to further oil spill. A high-level meeting of Maharashtra Government Environment department and other concerned agencies has been convened today to assess the situation and steps to be taken to bring it under control. Meanwhile Mumbai Port Trust (MbPT) has appointed SMIT Salvage, a Netherlands-based company to control the oil-spill, a senior port official said. The official said currently, the company is working hard with 11 vessels to look after the operation there. Directorate General of Shipping's Chief Nautical Advisor M M Saggi said Coast Guard officials are working hard to find out the leakage as the oil-spill is a major concern as one of the vessels was carrying over 2,000 tonnes of oil. All coastal districts of Maharashtra are on high alert as the oil slick has spread to the Alibaug and Uran areas, and also close to Elephanta caves. Concerns are that it may also affect the mangrove belt along the coastline. The Coast Guard has said it will be tough to contain the oil-spill because of tidal conditions. Meanwhile Maharashtra Chief Minister Ashok Chavan today undertook an aerial survey of the oil spill off the Mumbai coast. He said the state government was taking all necessary steps to contain the spill and described it as a matter of concern. The Directorate General of Shipping has initiated an investigation into the incident. Deputy police commissioner Khaled Qaiser said that an FIR has been registered against captains and crew members of both the cargo ships under relevant sections of IPC and Environment Protection Act at the Yellow Gate police station. So far nobody has been arrested, the DCP said adding that all the crew members will soon be summoned to the police station for questioning.Meanwhile Additional Coast Guard Pollution Response Equipment has also been mobilised from Goa and assistance is also being taken from ONGC, JNPT and other agencies. The state administration, Pollution Control Board, Maharashtra Maritime Board and the Bombay History Natural Society have been kept on high alert for mobilisation of response resources for shore clean up.
