We are receiving third grade coal DVC tells CIL

Kolkata . Alleging that substandard supplies have been causing it huge losses, power major Damodar Valley Corporation (DVC) has approached Coal India Ltd (CIL) for improved quality of coal after 78 per cent test results of third-party sampling have reported grade slippage -- with shale and stones found in the coal, an official said. 
 
DVC and other power generation companies had entered into tripartite agreements with the Central Institute of Mining and Fuel Research (CIMFR), under the Council of Scientific and Industrial Research (CSIR), and coal companies last August for third-party sampling and analysis at the loading end, a DVC official said. 
 
The power producer, which procures about 20 million tonnes of coal annually, used to source coal from CIL subsidiaries Bharat Coking Coal Ltd (BCCL), Central Coalfields Ltd (CCL), Eastern Coalfields Ltd (ECL) and Mahanadi Coalfields Ltd (MCL).
