Another reason given was that 'Talabira-II and III blocks needed to be developed together to extract an additional 30 million tonnes of coal which would have gone waste otherwise at the boundaries of each block'.
The third reason was that NLC and Mahanadi Coalfields Ltd can develop the two blocks together as one large mine through a Joint Venture (JV).
It noted that Birla had requested for allocation of Talabira-II to Hindalco reasoning that it was "the first applicant for it as long back as 1996" and that "the coal linkage granted earlier was not used as a bauxite mine lease relating to the aluminium plant had not materalised'.
