The country's hottest tourist destination, Goa, will go green as gas utility GAIL has suggested extending its proposed Dabhol-Bangalore pipeline to the state for supplying the environment-friendly fuel. The state-owned firm also plans to start supplying piped gas in kitchens of Karnataka and help launch CNG (compressed natural gas) services for automotive use in the state, according to chairman U D Choubey. Choubey made the proposal to clean up Goa's air during his February 5 meeting with chief minister Digambar Kamat in Panaji and suggested a similar service to Karnataka governor Rameshwar Thakur in Bangalore on Saturday. The GAIL board has already given an in-principle approval for laying the 730-km Dabhol-Bangalore gas pipeline at an estimated investment of Rs 2,500 crore. The proposal is to extend it to Goa by laying a spur line of about 120 km. Depending on the source and customers, the 30-inch Dabhol-Bangalore pipeline shall be designed to carry 16 million cubic metres per day of gas.
