New Delhi: An Inter-Ministerial Group, with an expanded mandate to review the status of 90 coal blocks allotted since 1993 to private firms, met today in New Delhi. Sources say the panel might recommend that licences for about 60 of these blocks be cancelled as the firms they were allotted to have failed to develop them. Sources say allottees of these blocks have been called-in for presenting their case. The firms stand to lose their bank guarantees, if they have not achieved the required development of the coal blocks. A final recommendation by the committee is expected to reach the Coal Secretary by September 10.
